Anna: Welcome to Astronomy Daily, your go to podcast
1
00:00:02.800 --> 00:00:05.200
for everything happening above our heads and beyond.
2
00:00:05.440 --> 00:00:08.200
I'm Anna and I'm thrilled to be your host as we
3
00:00:08.200 --> 00:00:11.160
explore the universe together. Today we've got a fascinating
4
00:00:11.160 --> 00:00:14.040
lineup of stories from the forefront of space exploration and
5
00:00:14.040 --> 00:00:16.760
astronomy. We'll be diving into some recent
6
00:00:16.760 --> 00:00:19.720
incidents, including a significant test anomaly
7
00:00:19.720 --> 00:00:22.320
for a key component of NASA's Space Launch System
8
00:00:22.640 --> 00:00:25.160
and the surprising legal challenges facing
9
00:00:25.160 --> 00:00:27.520
SpaceX over a Starship explosion.
10
00:00:28.350 --> 00:00:31.150
But it's not all about the dramatic events. We
11
00:00:31.150 --> 00:00:33.790
also have some truly captivating science to share,
12
00:00:34.270 --> 00:00:37.190
like the rare daytime fireball that may have impacted a
13
00:00:37.190 --> 00:00:40.110
home in Georgia and groundbreaking new research
14
00:00:40.270 --> 00:00:43.070
that might finally explain the mysterious differences
15
00:00:43.390 --> 00:00:46.030
between the near and far sides of our own
16
00:00:46.030 --> 00:00:48.430
moon. And for something a little different,
17
00:00:48.670 --> 00:00:51.430
we'll journey back in time to uncover the incredible
18
00:00:51.430 --> 00:00:54.350
true story of a con man who managed to fool
19
00:00:54.350 --> 00:00:55.710
the world as an astronaut.
20
00:00:55.870 --> 00:00:58.870
So settle in and let's get started on another exciting episode
21
00:00:58.870 --> 00:00:59.950
of Astronomy Daily.
22
00:01:01.690 --> 00:01:04.650
Delve into some significant news from the world of space exploration,
23
00:01:05.130 --> 00:01:07.610
specifically regarding NASA's Space Launch System,
24
00:01:07.930 --> 00:01:10.810
or SLS. On June 26,
25
00:01:10.810 --> 00:01:13.570
during a test firing in Utah, a new version of the
26
00:01:13.570 --> 00:01:16.090
solid rocket booster being developed for the SLS
27
00:01:16.170 --> 00:01:18.890
experienced an anomaly. This test was for
28
00:01:18.890 --> 00:01:21.810
Northrop Grumman's Booster Obsolescence and Life
29
00:01:21.810 --> 00:01:24.610
Extension, or bol, version of the five
30
00:01:24.610 --> 00:01:27.430
segment solid rocket booster. The booster,
31
00:01:27.430 --> 00:01:30.270
fixed horizontally, was undergoing a, uh, two minute
32
00:01:30.270 --> 00:01:33.190
firing simulating a real launch. A little over
33
00:01:33.190 --> 00:01:36.030
100 seconds into the test, observers noted exhaust
34
00:01:36.030 --> 00:01:38.990
appearing from the side of the nozzle, followed by debris
35
00:01:38.990 --> 00:01:41.670
scattering from that same area. Despite
36
00:01:41.670 --> 00:01:44.630
this, the motor continued to burn for the rest of
37
00:01:44.630 --> 00:01:47.310
the test. Initially, NASA and
38
00:01:47.310 --> 00:01:50.190
Northrop Grumman officials didn't publicly address the
39
00:01:50.190 --> 00:01:52.640
incident during their webcast. However,
40
00:01:53.040 --> 00:01:55.760
a few hours later, Jim Calborer,
41
00:01:55.920 --> 00:01:58.560
vice president of Propulsion systems at Northrop
42
00:01:58.560 --> 00:02:00.920
Grumman, released a statement confirming the
43
00:02:00.920 --> 00:02:03.840
anomaly. He noted that while the motor seemed
44
00:02:03.840 --> 00:02:06.720
to perform well through a harsh burn environment, the
45
00:02:06.720 --> 00:02:09.680
issue occurred near the end of the burn. Kalberer
46
00:02:09.680 --> 00:02:12.440
added that the company was pushing the boundaries of
47
00:02:12.440 --> 00:02:15.400
large solid rocket motor design and
48
00:02:15.400 --> 00:02:18.240
that this new, largest ever segmented
49
00:02:18.240 --> 00:02:21.090
solid rocket booster test provides valuable
50
00:02:21.090 --> 00:02:23.810
data for future developments. The
51
00:02:23.810 --> 00:02:26.570
bowl design is intended to be used for SLS
52
00:02:26.570 --> 00:02:29.530
missions starting with Artemis 9, projected for the
53
00:02:29.530 --> 00:02:32.530
2000-30s. Its key improvements include replacing
54
00:02:32.530 --> 00:02:35.410
the shuttle era steel casings with new carbon
55
00:02:35.410 --> 00:02:38.410
fibre composite designs using a uh, new propellant
56
00:02:38.410 --> 00:02:41.210
formulation and incorporating other advancements that
57
00:02:41.210 --> 00:02:44.130
boost its performance by over 10%. This
58
00:02:44.130 --> 00:02:46.770
would allow an additional 5 metric tonnes of payload for
59
00:02:46.770 --> 00:02:48.730
SLS missions heading to the moon.
60
00:02:49.730 --> 00:02:52.450
However, there's a degree of uncertainty about whether the bowl design
61
00:02:52.450 --> 00:02:55.450
will actually fly. NASA's fiscal year
62
00:02:55.450 --> 00:02:58.090
2026 budget proposal aims to cancel the
63
00:02:58.090 --> 00:03:00.370
SLS after the Artemis 3 mission.
64
00:03:01.090 --> 00:03:03.890
While a provision in the Senate's budget reconciliation bill
65
00:03:03.890 --> 00:03:06.610
could add funding for two more SLS missions
66
00:03:06.850 --> 00:03:09.850
through Artemis V, it doesn't clarify the vehicle's
67
00:03:09.850 --> 00:03:12.370
future beyond that. Interestingly,
68
00:03:12.770 --> 00:03:15.530
this isn't the first time a Northrop Grumman solid
69
00:03:15.530 --> 00:03:18.490
rocket booster has faced a nozzle issue in less than a
70
00:03:18.490 --> 00:03:21.050
year. Back in October 2024,
71
00:03:21.370 --> 00:03:23.850
a nozzle detached from one of the much smaller
72
00:03:23.850 --> 00:03:26.730
GEM3.6XL solid rocket boosters
73
00:03:26.970 --> 00:03:29.770
on the second launch of United Launch Alliance's Vulcan
74
00:03:29.770 --> 00:03:32.730
rocket. While that issue did degrade the booster's performance
75
00:03:32.810 --> 00:03:35.210
somewhat, it didn't prevent Vulcan from
76
00:03:35.210 --> 00:03:37.970
successfully completing its mission. ULA
77
00:03:37.970 --> 00:03:40.930
later confirmed in March that a manufacturing defect in
78
00:03:40.930 --> 00:03:43.890
one of the internal parts of the nozzle caused it to
79
00:03:43.890 --> 00:03:46.610
come off, and fixes to correct this problem
80
00:03:47.010 --> 00:03:49.570
were successfully confirmed in a test
81
00:03:49.570 --> 00:03:52.530
firing in February. These
82
00:03:52.530 --> 00:03:55.450
incidents highlight the complex and challenging
83
00:03:55.450 --> 00:03:57.850
nature of developing such powerful
84
00:03:57.850 --> 00:03:59.170
propulsion systems.
85
00:04:00.609 --> 00:04:03.290
Now let's turn our gaze from man made rockets to a natural
86
00:04:03.290 --> 00:04:06.250
phenomenon that recently put on quite a show. A large
87
00:04:06.250 --> 00:04:09.130
meteor created a spectacular, rare daytime fireball
88
00:04:09.130 --> 00:04:11.860
over the southeastern United States on a Friday at
89
00:04:11.860 --> 00:04:14.660
12:25pm Eastern Daylight Time. This
90
00:04:14.660 --> 00:04:17.460
wasn't just any meteor. It was so bright that it was
91
00:04:17.460 --> 00:04:20.260
even seen by the National oceanic and Atmospheric
92
00:04:20.260 --> 00:04:22.820
Administration's GOES 19 Earth observation
93
00:04:22.820 --> 00:04:25.420
satellite, using an instrument designed to map
94
00:04:25.420 --> 00:04:28.020
flashes of lightning from orbit. Daylight
95
00:04:28.020 --> 00:04:30.940
fireballs are truly uncommon, according to Robert
96
00:04:30.940 --> 00:04:33.700
Lunsford of the American Meteor Association. It
97
00:04:33.700 --> 00:04:36.660
takes a significantly large object, much bigger
98
00:04:36.660 --> 00:04:39.530
than your average pea sized meteor, to be bright enough to
99
00:04:39.530 --> 00:04:42.530
be visible during the day. He notes that we probably only
100
00:04:42.530 --> 00:04:45.450
see about one per month worldwide, meaning only about
101
00:04:45.450 --> 00:04:48.410
one in every 3,000 meteor reports occurs during
102
00:04:48.410 --> 00:04:51.370
daylight hours. This particular meteor was
103
00:04:51.370 --> 00:04:54.050
first spotted approximately 48 miles above Oxford,
104
00:04:54.050 --> 00:04:56.730
Georgia, hurtling through the atmosphere at around
105
00:04:56.730 --> 00:04:59.730
30,000 miles per hour. Experts
106
00:04:59.730 --> 00:05:02.370
suggest it might have been associated with the daytime
107
00:05:02.370 --> 00:05:05.290
Beta Taurid shower, which peaks in late June as
108
00:05:05.290 --> 00:05:08.130
Earth passes through debris from the ancient comet 2P
109
00:05:08.370 --> 00:05:11.170
Enker. What makes this event even more
110
00:05:11.170 --> 00:05:14.090
intriguing is the strong possibility that fragments of
111
00:05:14.090 --> 00:05:17.050
the meteor survived its fiery descent and
112
00:05:17.130 --> 00:05:20.010
impacted the ground. In the hours following
113
00:05:20.010 --> 00:05:22.650
the fireball, photos began circulating online,
114
00:05:23.210 --> 00:05:26.010
purportedly showing a hole punched through the roof of a home
115
00:05:26.010 --> 00:05:28.730
in Henry County, Georgia. The size of this
116
00:05:28.730 --> 00:05:31.610
meteor meant it had a better chance of producing fragments.
117
00:05:32.090 --> 00:05:34.770
Scientists look for reports of sounds like thunder
118
00:05:34.770 --> 00:05:37.700
or something, sonic booms, which indicate that parts of
119
00:05:37.700 --> 00:05:40.580
the fireball made it down to the lower atmosphere
120
00:05:40.740 --> 00:05:43.060
and potentially all the way to the ground.
121
00:05:43.940 --> 00:05:46.900
This strongly suggests the photograph of the hole in the roof
122
00:05:47.060 --> 00:05:49.460
is indeed connected to this celestial
123
00:05:49.460 --> 00:05:52.420
visitor. And if verified, it wouldn't
124
00:05:52.420 --> 00:05:55.140
be the first time a daytime Beta Taurid left its mark.
125
00:05:55.940 --> 00:05:58.580
Lunsford mentioned a particularly large meteor
126
00:05:58.820 --> 00:06:01.650
believed to be linked to this annual shower that
127
00:06:01.650 --> 00:06:04.610
detonated in a powerful air burst just six miles
128
00:06:04.610 --> 00:06:07.570
over Russian Siberia in June 1908.
129
00:06:07.890 --> 00:06:10.610
That explosion, known as the Tunguska Event,
130
00:06:10.930 --> 00:06:13.610
ignited massive forest fires and flattened an
131
00:06:13.610 --> 00:06:16.330
estimated 80 million trees. It's a
132
00:06:16.330 --> 00:06:19.210
powerful reminder of the impact these space rocks can
133
00:06:19.210 --> 00:06:22.010
have even when they don't directly hit the
134
00:06:22.010 --> 00:06:24.610
surface from natural
135
00:06:24.610 --> 00:06:25.170
impacts.
136
00:06:25.330 --> 00:06:27.970
We now shift our focus to human made space endeavours.
137
00:06:28.490 --> 00:06:31.130
Specifically, the latest legal challenges faced by
138
00:06:31.130 --> 00:06:33.690
SpaceX. The Mexican president,
139
00:06:33.690 --> 00:06:36.610
Claudia Sheinbaum, has recently threatened to file
140
00:06:36.610 --> 00:06:39.370
a lawsuit against SpaceX, citing alleged
141
00:06:39.370 --> 00:06:42.290
contamination resulting from a starship explosion that
142
00:06:42.290 --> 00:06:45.290
occurred earlier this month. On June 18,
143
00:06:45.530 --> 00:06:48.450
SpaceX was conducting a test of the upper stage of
144
00:06:48.450 --> 00:06:51.330
its starship vehicle at its Starbase facility near
145
00:06:51.330 --> 00:06:54.300
Boca Chica beach in Texas. This test
146
00:06:54.300 --> 00:06:56.900
culminated in a dramatic fireball. While
147
00:06:56.900 --> 00:06:59.820
SpaceX stated on social media that there were no hazards to
148
00:06:59.820 --> 00:07:02.540
the surrounding communities, President Sheinbaum is
149
00:07:02.540 --> 00:07:05.140
contesting that claim. During a press
150
00:07:05.140 --> 00:07:08.020
conference, she indicated that a general review
151
00:07:08.020 --> 00:07:10.860
is underway of the international laws that are
152
00:07:10.860 --> 00:07:13.500
being violated. Specifically due to this
153
00:07:13.500 --> 00:07:16.380
perceived contamination, the Mexican
154
00:07:16.380 --> 00:07:19.140
government is looking to file the necessary lawsuits.
155
00:07:19.870 --> 00:07:22.270
It's worth noting the geographical context here.
156
00:07:22.910 --> 00:07:25.830
SpaceX's Starbase facility is located at the
157
00:07:25.830 --> 00:07:28.710
very southeastern tip of Texas, right along the
158
00:07:28.710 --> 00:07:31.670
Rio Grande river, which acts as the border between the
159
00:07:31.670 --> 00:07:34.630
United States and Mexico. Just across this border
160
00:07:34.630 --> 00:07:37.590
from Boca Chica and nearby Brownsville, Texas, lies the
161
00:07:37.590 --> 00:07:39.710
Mexican city of Heroica Matamoros.
162
00:07:40.590 --> 00:07:43.590
This isn't the first time SpaceX has faced environmental
163
00:07:43.590 --> 00:07:46.230
lawsuits or other legal challenges. In
164
00:07:46.230 --> 00:07:48.990
2023, a coalition of environmental
165
00:07:48.990 --> 00:07:51.830
groups sued the US Federal Aviation Administration,
166
00:07:52.390 --> 00:07:55.310
alleging that the agency hadn't properly analysed
167
00:07:55.310 --> 00:07:58.310
the potential damage Starship could inflict on the surrounding areas,
168
00:07:58.550 --> 00:08:00.870
which are, uh, home to protected bird species.
169
00:08:01.589 --> 00:08:04.190
More recently, in 2024, the
170
00:08:04.190 --> 00:08:07.030
Texas Commission on Environmental Quality reported that
171
00:08:07.030 --> 00:08:09.670
SpaceX had violated the Clean Water act by
172
00:08:09.670 --> 00:08:12.070
releasing pollutants into nearby bodies of water.
173
00:08:12.590 --> 00:08:14.830
Though SpaceX refuted these claims as
174
00:08:14.990 --> 00:08:17.590
factually inaccurate, past
175
00:08:17.590 --> 00:08:20.110
starship launches, and particularly explosions,
176
00:08:20.430 --> 00:08:23.430
have indeed left significant amounts of debris scattered across
177
00:08:23.430 --> 00:08:26.150
Boca Chica beach and its environs. The
178
00:08:26.150 --> 00:08:29.150
debut flight of Starship on April 20, 2023,
179
00:08:29.310 --> 00:08:32.030
saw the rocket's 33 first stage Raptor
180
00:08:32.030 --> 00:08:34.990
engines propel chunks of cement and other debris for
181
00:08:34.990 --> 00:08:37.750
miles. Local residents describe that launch
182
00:08:37.750 --> 00:08:40.540
as terrifying and likened it to an earthquake,
183
00:08:40.620 --> 00:08:42.940
with debris even crushing a nearby car.
184
00:08:43.500 --> 00:08:46.060
That flight also ended dramatically when SpaceX
185
00:08:46.060 --> 00:08:48.700
initiated its onboard flight termination system,
186
00:08:49.100 --> 00:08:52.060
causing the vehicle to explode about three minutes after
187
00:08:52.060 --> 00:08:55.019
liftoff, with fragments found along the shores.
188
00:08:55.019 --> 00:08:57.540
In the days that followed. To date,
189
00:08:57.540 --> 00:09:00.540
Starship's upper stage has exploded or crashed into
190
00:09:00.540 --> 00:09:02.940
the sea on eight of its nine test flights.
191
00:09:03.260 --> 00:09:05.900
Underscoring the experimental nature of these ambitious
192
00:09:05.900 --> 00:09:08.460
endeavours, these incidents highlight the
193
00:09:08.460 --> 00:09:10.940
ongoing environmental considerations as, uh, space
194
00:09:10.940 --> 00:09:13.380
exploration continues to push boundaries
195
00:09:14.660 --> 00:09:17.460
from the complexities of earthly legal battles in space.
196
00:09:17.860 --> 00:09:20.740
We now pivot to the ancient mysteries of our Moon,
197
00:09:21.140 --> 00:09:23.900
specifically the enduring puzzle of why its near
198
00:09:23.900 --> 00:09:26.860
side looks so different from its far side. For
199
00:09:26.860 --> 00:09:29.740
a long time, this was one of the Moon's most intriguing
200
00:09:29.740 --> 00:09:32.260
secrets. Until 1959,
201
00:09:32.720 --> 00:09:35.520
when the USSR's Luna 3 spacecraft first
202
00:09:35.520 --> 00:09:38.120
circled the Moon and sent back grainy black and white
203
00:09:38.120 --> 00:09:40.920
images, humans had never actually seen the lunar
204
00:09:40.920 --> 00:09:43.800
far side. What those images revealed was a stark
205
00:09:43.800 --> 00:09:46.800
contrast. The far side was heavily cratered, with
206
00:09:46.800 --> 00:09:49.600
far fewer of the dark volcanic plains known as
207
00:09:49.600 --> 00:09:52.480
maria that so distinctly mark the near side.
208
00:09:53.280 --> 00:09:56.200
This immediate visual difference prompted many questions
209
00:09:56.200 --> 00:09:58.930
about the Moon's formation and evolution. Was
210
00:09:58.930 --> 00:10:01.890
Earth's gravitational pull responsible? Or perhaps
211
00:10:01.890 --> 00:10:04.690
a difference in crustal thickness? Scientists
212
00:10:04.690 --> 00:10:07.610
realised the Moon wasn't a uniform body and the search
213
00:10:07.610 --> 00:10:09.570
for answers has continued ever since.
214
00:10:10.530 --> 00:10:12.970
Now, new research published in Nature
215
00:10:12.970 --> 00:10:15.450
Communications, led by Ji Jun Jing from
216
00:10:15.450 --> 00:10:18.170
Ihime University in Japan, offers a
217
00:10:18.170 --> 00:10:21.130
compelling explanation that points to trace amounts of certain
218
00:10:21.130 --> 00:10:24.010
minerals. The study focuses on chlorine and
219
00:10:24.010 --> 00:10:26.850
fluorine and their presence in lunar minerals and melts.
220
00:10:27.650 --> 00:10:30.130
It highlights that most near side lunar crust
221
00:10:30.130 --> 00:10:32.570
materials show an unusual enrichment in
222
00:10:32.570 --> 00:10:35.570
chlorine, a ah finding that doesn't quite fit with traditional
223
00:10:35.570 --> 00:10:38.490
models of primary crust formation. This anomaly,
224
00:10:38.490 --> 00:10:41.370
the researchers suggest, is likely due to a process
225
00:10:41.370 --> 00:10:42.770
called metasomatism.
226
00:10:43.490 --> 00:10:46.250
Metasomatism is a geological process where a
227
00:10:46.250 --> 00:10:48.930
rock's chemical composition is altered when new
228
00:10:48.930 --> 00:10:51.690
chemical elements are introduced, often by water or
229
00:10:51.690 --> 00:10:54.680
magma. M In the lunar context, the research
230
00:10:54.760 --> 00:10:57.320
indicates that gaseous chlorine compounds
231
00:10:57.480 --> 00:11:00.360
found their way into near side lunar rocks through this
232
00:11:00.360 --> 00:11:03.240
process, while farside samples don't show the same
233
00:11:03.240 --> 00:11:05.920
enrichment. Another key piece of this
234
00:11:05.920 --> 00:11:08.360
lunar puzzle is what's known as the Moon's creep
235
00:11:08.360 --> 00:11:11.200
terrain. This is a large region exclusively
236
00:11:11.200 --> 00:11:14.040
found on the Moon's near side, characterised by high
237
00:11:14.040 --> 00:11:17.000
concentrations of potassium, rare earth elements
238
00:11:17.080 --> 00:11:19.970
and phosphorus, hence the acronym
239
00:11:19.970 --> 00:11:22.450
creep. It's also known for its significant
240
00:11:22.610 --> 00:11:25.410
thorium concentrations. Creep is
241
00:11:25.410 --> 00:11:28.130
crucial to Understanding the moon's early evolution after its
242
00:11:28.130 --> 00:11:31.130
global magma ocean phase. While creep was
243
00:11:31.130 --> 00:11:34.050
likely widespread initially, it's now confined to this
244
00:11:34.050 --> 00:11:36.850
one region, possibly due to the massive impact
245
00:11:37.010 --> 00:11:40.010
that created the south pole Aitken Basin on the
246
00:11:40.010 --> 00:11:42.970
opposite side of the Moon. That impact might
247
00:11:42.970 --> 00:11:45.720
have generated a thermal anomaly and that drove the
248
00:11:45.720 --> 00:11:48.640
creep towards the near side. The new
249
00:11:48.640 --> 00:11:51.240
research suggests a strong connection between widespread
250
00:11:51.240 --> 00:11:54.160
chlorine vapour on the lunar near side and
251
00:11:54.160 --> 00:11:57.040
this lunar dichotomy. They hypothesise that
252
00:11:57.040 --> 00:11:59.960
this chlorine metasomatism is likely related to
253
00:11:59.960 --> 00:12:02.840
degassing caused by impacts or eruptions from the creep
254
00:12:02.840 --> 00:12:05.360
terrain. Chlorine is highly volatile and
255
00:12:05.360 --> 00:12:08.240
incompatible, meaning it doesn't easily fit into the
256
00:12:08.240 --> 00:12:10.640
crystal structure of minerals. As magma cools,
257
00:12:11.220 --> 00:12:14.140
so chlorine rich vapours released during volcanic eruptions or
258
00:12:14.140 --> 00:12:16.940
impact induced evaporation likely played a key role in
259
00:12:16.940 --> 00:12:19.700
transforming the moon's near side, the side we see most
260
00:12:19.700 --> 00:12:22.660
clearly. Conversely, the far side, untouched
261
00:12:22.660 --> 00:12:25.620
by these vapour related volcanic activities, may be more
262
00:12:25.620 --> 00:12:28.540
pristine, preserving information from the moon's very early
263
00:12:28.540 --> 00:12:31.460
magma ocean phase. While this research
264
00:12:31.540 --> 00:12:33.820
provides a strong hypothesis for the lunar
265
00:12:33.820 --> 00:12:36.700
dichotomy, the authors emphasise that more
266
00:12:36.700 --> 00:12:39.640
evidence is needed. This is where future missions
267
00:12:39.640 --> 00:12:42.320
come in. China has already landed two
268
00:12:42.320 --> 00:12:45.080
missions on the lunar far side, including the Chang'
269
00:12:45.080 --> 00:12:47.800
E6 mission, which successfully gathered
270
00:12:47.800 --> 00:12:50.400
samples. The authors believe that
271
00:12:50.400 --> 00:12:53.160
measurements of halogens in these Farside Chang'
272
00:12:53.160 --> 00:12:55.960
E6 samples could provide the crucial evidence
273
00:12:55.960 --> 00:12:58.080
needed to strengthen their explanation.
274
00:12:58.960 --> 00:13:01.680
It's a truly exciting prospect for lunar science
275
00:13:03.120 --> 00:13:05.960
from deep space. We now turn our attention back to
276
00:13:05.960 --> 00:13:08.440
Earth, specifically to a captivating,
277
00:13:08.440 --> 00:13:11.280
unbelievable but true story of a con man
278
00:13:11.360 --> 00:13:14.200
who for a time managed to fool the world into
279
00:13:14.200 --> 00:13:15.760
believing he was an astronaut.
280
00:13:17.840 --> 00:13:20.320
A cold January evening in 1989.
281
00:13:21.200 --> 00:13:23.880
Members of the Experimental Aircraft association of
282
00:13:23.880 --> 00:13:26.400
Boston are eagerly awaiting a special guest.
283
00:13:26.720 --> 00:13:29.560
The President introduces him as a master of the
284
00:13:29.560 --> 00:13:32.320
skies and space. Onto the stage
285
00:13:32.400 --> 00:13:34.960
strides US Marine Captain Robert J. Hunt,
286
00:13:35.280 --> 00:13:38.040
27 years old, handsome, with a confident
287
00:13:38.040 --> 00:13:41.040
air and dressed in a powder blue NASA flight suit
288
00:13:41.040 --> 00:13:43.920
complete with shining space patches. Hunt
289
00:13:43.920 --> 00:13:46.920
captivated the amateur pilots with fantastic tales of
290
00:13:46.920 --> 00:13:49.400
his life as a Marine fighter pilot bombing
291
00:13:49.400 --> 00:13:52.000
Gaddafi's Libya from his F A18 jet.
292
00:13:52.480 --> 00:13:55.000
But his most astonishing claims involved
293
00:13:55.000 --> 00:13:58.000
soaring above Earth aboard the space shuttle Atlantis
294
00:13:58.080 --> 00:14:00.720
on top secret missions for the Department of Defence.
295
00:14:01.520 --> 00:14:04.360
He even presented two blackened tiles which he
296
00:14:04.360 --> 00:14:07.120
claimed were scorched during his re entry. Despite
297
00:14:07.120 --> 00:14:10.080
some members suspicions like Joy Alexander, who found
298
00:14:10.240 --> 00:14:12.760
his thick New England accent and rude attitude
299
00:14:12.760 --> 00:14:15.480
unsettling for a NASA astronaut, most were
300
00:14:15.480 --> 00:14:18.400
spellbound. Hunt shook hands, scribbled autographs
301
00:14:18.400 --> 00:14:21.080
and left the aviation enthusiasts believing they had met a
302
00:14:21.080 --> 00:14:24.000
legend. But Robert J Hunt had never been
303
00:14:24.000 --> 00:14:27.000
to space. He didn't even have a pilot's licence, let
304
00:14:27.000 --> 00:14:29.750
alone a driver's licence. He was an imposter,
305
00:14:29.750 --> 00:14:32.110
and his incredible scam would soon make national
306
00:14:32.110 --> 00:14:35.030
headlines, leading to his arrest in less than a
307
00:14:35.030 --> 00:14:37.990
week. Hunt had been leading law enforcement on a cat
308
00:14:37.990 --> 00:14:40.910
and mouse chase for years, posing as a Marine,
309
00:14:41.230 --> 00:14:43.910
a baseball star, a senator and other prominent
310
00:14:43.910 --> 00:14:46.870
figures often escaping prosecution. It was
311
00:14:46.870 --> 00:14:49.390
only when he became an astronaut that he triggered a security
312
00:14:49.470 --> 00:14:51.790
panic, embarrassed politicians and
313
00:14:51.790 --> 00:14:54.720
captivated the nation. Hunt's obsession
314
00:14:54.720 --> 00:14:57.600
with space began at age 7. Watching the
315
00:14:57.600 --> 00:15:00.240
Apollo 11 moon landing. He felt a deep
316
00:15:00.240 --> 00:15:02.880
connection to astronauts like Neil Armstrong and Alan
317
00:15:02.880 --> 00:15:05.600
Shepard. As a teenager, he would sneak into
318
00:15:05.600 --> 00:15:08.600
Chelsea Naval Hospital, slip on discarded uniforms
319
00:15:08.760 --> 00:15:11.440
and salute himself in the mirror, dreaming of
320
00:15:11.440 --> 00:15:14.160
exploring distant planets. His
321
00:15:14.160 --> 00:15:16.840
father, Leo Hunt, a plumber who also
322
00:15:16.840 --> 00:15:19.600
pretended to be a military colonel, unknowingly
323
00:15:19.600 --> 00:15:22.460
influenced him and even writing a book about his alleged
324
00:15:22.460 --> 00:15:24.940
life in the military titled Colonel Chameleon.
325
00:15:25.420 --> 00:15:28.300
Robert Hunt claims his father taught him the art of deception,
326
00:15:28.300 --> 00:15:30.900
like when he sold sparrows painted yellow as
327
00:15:30.900 --> 00:15:33.660
canaries. Robert's first steps into
328
00:15:33.660 --> 00:15:36.659
grander deceptions came early. He claimed to join
329
00:15:36.659 --> 00:15:38.700
the Marine Corps on a delayed entry programme,
330
00:15:39.340 --> 00:15:41.700
was supposedly honourably discharged due to an
331
00:15:41.700 --> 00:15:44.700
administrative error, and then simply bluffed his way back into
332
00:15:44.700 --> 00:15:47.340
barracks, knowing the commands and structure.
333
00:15:47.820 --> 00:15:50.740
He even snuck onto Pease Air Force Base dressed as a
334
00:15:50.740 --> 00:15:53.460
second lieutenant, and was caught poking around Air Force
335
00:15:53.460 --> 00:15:56.460
Two, the Vice President's plane. This
336
00:15:56.460 --> 00:15:59.380
incident triggered an FBI investigation and ended his
337
00:15:59.380 --> 00:16:01.660
first marriage. His cons
338
00:16:01.740 --> 00:16:04.740
escalated. He married again, claiming to be
339
00:16:04.740 --> 00:16:07.580
a college graduate with a baseball contract. He
340
00:16:07.580 --> 00:16:10.580
even invented a spray on diaper cream called Love My
341
00:16:10.580 --> 00:16:13.220
Baby, falsely claiming a multi million dollar
342
00:16:13.220 --> 00:16:16.090
buyout was imminent. Using his wife's credit
343
00:16:16.090 --> 00:16:18.730
card, he rented limos and posed as a TV
344
00:16:18.730 --> 00:16:21.730
producer to cast a Super bowl commercial, only to be
345
00:16:21.730 --> 00:16:24.650
busted by police, who described him as a smooth talker.
346
00:16:25.370 --> 00:16:28.010
After these setbacks, Hunt fled back to the
347
00:16:28.010 --> 00:16:30.770
military, using fake credentials to acquire flight
348
00:16:30.770 --> 00:16:33.730
uniforms and promoting himself from marine pilot to Captain
349
00:16:33.730 --> 00:16:36.410
Hunt, America's youngest Marine astronaut,
350
00:16:36.570 --> 00:16:39.130
complete with $20 Navy astronaut wings.
351
00:16:39.370 --> 00:16:42.250
He claimed to have bluffed his way into NASA astronaut
352
00:16:42.250 --> 00:16:44.830
training, undergoing physical evaluations at
353
00:16:44.830 --> 00:16:47.710
Johnson Space Centre and studying in Rocket City,
354
00:16:47.710 --> 00:16:50.630
Huntsville, Alabama. He even said he spent
355
00:16:50.710 --> 00:16:53.590
nine weeks with Morton Thiokol, the company that
356
00:16:53.590 --> 00:16:56.470
built solid rocket boosters. While none of
357
00:16:56.470 --> 00:16:59.150
these claims are verified, Hunt's narrative was
358
00:16:59.150 --> 00:17:01.990
detailed enough to convince many, including his fourth
359
00:17:01.990 --> 00:17:04.710
wife, Ann Sweeney, an optical engineer.
360
00:17:05.030 --> 00:17:07.790
He whisked her away on private jets and exotic
361
00:17:07.790 --> 00:17:10.619
vacations, paying with her corporate credit card.
362
00:17:11.179 --> 00:17:14.019
The pinnacle of his astronaut hoax came in December
363
00:17:14.019 --> 00:17:16.899
1988 when he travelled to Ireland to visit
364
00:17:16.899 --> 00:17:19.899
his brother in law on the Aer Lingus flight.
365
00:17:19.899 --> 00:17:22.539
He charmed the crew and was invited into the cockpit.
366
00:17:22.699 --> 00:17:25.339
Upon landing in Dublin, he was shocked to be greeted by
367
00:17:25.339 --> 00:17:27.979
smiling Irish government officials and a small
368
00:17:27.979 --> 00:17:30.819
band playing the national anthem. He didn't even go
369
00:17:30.819 --> 00:17:33.259
through customs. Hunt played along,
370
00:17:33.499 --> 00:17:36.130
giving speeches, accepting awards and
371
00:17:36.130 --> 00:17:39.050
sipping tea with Dublin's Lord Mayor, Ben Briscoe,
372
00:17:39.210 --> 00:17:41.930
who, despite his suspicions, politely let the spectacle
373
00:17:41.930 --> 00:17:44.850
continue. Hunt left Ireland with souvenirs
374
00:17:44.850 --> 00:17:47.810
and honorary Irish citizenship, claiming it
375
00:17:47.810 --> 00:17:50.529
all just got out of control. Back in the
376
00:17:50.529 --> 00:17:52.650
US his scheme began to unravel.
377
00:17:53.450 --> 00:17:56.450
American Express rejected a $5,000 charge for the
378
00:17:56.450 --> 00:17:58.970
private jet trip, alerting his wife's employer,
379
00:17:58.970 --> 00:18:01.700
Polaroid. Massachusetts State Trooper
380
00:18:01.700 --> 00:18:04.180
Andrew Palombo began investigating Hunt
381
00:18:04.420 --> 00:18:07.260
after a woman complained he had convinced her son to
382
00:18:07.260 --> 00:18:10.140
enlist, then demanded $4,000
383
00:18:10.140 --> 00:18:13.060
to use his Pentagon connections for a discharge.
384
00:18:13.620 --> 00:18:16.620
Palombo, a diligent and tough investigator,
385
00:18:16.620 --> 00:18:19.420
quickly discovered Hunt's military records showed only
386
00:18:19.420 --> 00:18:21.820
two months in the Marine Reserve, ending with a
387
00:18:21.820 --> 00:18:24.740
psychological evaluation. On January
388
00:18:24.820 --> 00:18:27.750
28, 1989, Palambo knocked on
389
00:18:27.750 --> 00:18:30.750
Hunt's door. A search of his home revealed military
390
00:18:30.750 --> 00:18:33.430
paraphernalia, flight jumpsuits, a NASA
391
00:18:33.430 --> 00:18:36.350
helmet, police badges and photos of Hunt wearing Korean War
392
00:18:36.350 --> 00:18:39.150
medals. His wife, Ann Sweeney, surrendered two
393
00:18:39.150 --> 00:18:42.150
scorched space shuttle tiles, which Palambo identified
394
00:18:42.150 --> 00:18:45.110
as ordinary floor tiles. Hunt was arrested for
395
00:18:45.110 --> 00:18:47.910
larceny. Palambo was relentless, discovering a
396
00:18:47.910 --> 00:18:50.670
fake doctor's ID and confirming that Hunt's military
397
00:18:50.670 --> 00:18:52.590
uniforms were acquired fraudulently.
398
00:18:53.510 --> 00:18:56.150
NASA and FBI determined that impersonating an
399
00:18:56.150 --> 00:18:59.030
astronaut wasn't illegal unless other crimes were involved.
400
00:18:59.110 --> 00:19:02.110
But Palambo logged Hunt's astronaut gear as evidence of
401
00:19:02.110 --> 00:19:04.990
his fraud. Ann Sweeney was devastated to
402
00:19:04.990 --> 00:19:07.990
learn her husband was a con man. It was almost like watching
403
00:19:07.990 --> 00:19:10.950
someone die, she told the Herald. Here was this
404
00:19:10.950 --> 00:19:13.750
person I thought I knew. And bit by bit, in the course of an
405
00:19:13.750 --> 00:19:16.550
hour, he just dissolved, just disappeared.
406
00:19:17.270 --> 00:19:20.070
She realised she had fallen victim to the ostrich effect,
407
00:19:20.560 --> 00:19:23.240
a psychological phenomenon where people bury their heads in the
408
00:19:23.240 --> 00:19:25.840
sand, operating under a truth bias,
409
00:19:26.240 --> 00:19:29.240
assuming others are honest. Hunt pleaded
410
00:19:29.240 --> 00:19:32.240
guilty to larceny and received a two year suspended sentence.
411
00:19:32.720 --> 00:19:35.720
After his release. In May 1989, he announced his
412
00:19:35.720 --> 00:19:38.480
candidacy for mayor of Revere, Massachusetts. But
413
00:19:38.480 --> 00:19:40.800
Trooper Palambo continued to pursue him.
414
00:19:41.200 --> 00:19:44.000
Hunt failed to pay restitution and skipped town, becoming a
415
00:19:44.000 --> 00:19:47.000
fugitive. Television crews interviewed his former wives who
416
00:19:47.000 --> 00:19:49.950
compared notes on set. His cons continued, leading him
417
00:19:49.950 --> 00:19:52.830
to pose as the head of Seal Team 6 at a US military
418
00:19:52.830 --> 00:19:55.470
base in San Francisco. There, he even
419
00:19:55.470 --> 00:19:57.950
berated an elderly man who questioned his authority,
420
00:19:58.350 --> 00:20:01.270
only to later realise it was Apollo astronaut Eugene
421
00:20:01.270 --> 00:20:03.590
cernan. Finally, in July
422
00:20:03.590 --> 00:20:06.590
1994, he was charged with false impersonation,
423
00:20:06.670 --> 00:20:09.150
pleaded guilty and served a year in prison.
424
00:20:10.030 --> 00:20:12.910
After his release, Hunt's cons persisted, with
425
00:20:12.910 --> 00:20:15.770
Palambo doggedly pursuing him until the trooper's death. And
426
00:20:15.840 --> 00:20:18.800
in 1998, with stricter security after
427
00:20:18.800 --> 00:20:21.760
911 and the Stolen Valour act of 2005
428
00:20:21.760 --> 00:20:24.640
making it illegal to falsely claim military decorations,
429
00:20:24.960 --> 00:20:27.960
Hunt's schemes became impossible. He finally
430
00:20:27.960 --> 00:20:30.640
hung up his fake uniforms and tried to rebuild his life,
431
00:20:30.960 --> 00:20:33.920
expressing regret for the hurt he caused his ex wives.
432
00:20:34.560 --> 00:20:37.280
While he maintained some incredible claims about flying real
433
00:20:37.280 --> 00:20:39.960
fighter jets, investigations by NASA and
434
00:20:39.960 --> 00:20:42.960
military records confirmed that Robert Hunt had no
435
00:20:42.960 --> 00:20:45.040
legitimate military or astronaut service.
436
00:20:46.230 --> 00:20:49.110
Today, Robert J. Hunt lives alone in New Hampshire, working
437
00:20:49.110 --> 00:20:52.110
in Construction. At 63, he reflects on
438
00:20:52.110 --> 00:20:54.910
his past. He once said, when I'm wearing a
439
00:20:54.910 --> 00:20:57.670
blue flight suit and everybody else is wearing a grey or green
440
00:20:57.670 --> 00:21:00.430
one, you stand out. Like, this guy is the super
441
00:21:00.430 --> 00:21:03.030
guru of pilots, so they all want to be your friend
442
00:21:03.910 --> 00:21:06.790
for a brief, extraordinary moment. Like the
443
00:21:06.790 --> 00:21:09.390
sparrows he once painted yellow, Hunt's
444
00:21:09.390 --> 00:21:12.210
deceptions allowed him to truly believe he could
445
00:21:12.210 --> 00:21:13.130
touch the stars.
446
00:21:15.130 --> 00:21:18.090
And with that incredible story, we're calling time
447
00:21:18.090 --> 00:21:20.690
on today's episode of Astronomy Daily. A final
448
00:21:20.690 --> 00:21:23.570

Bye.
0
00:00:00.000 --> 00:00:02.800
Anna: Welcome to Astronomy Daily, your go to podcast
1
00:00:02.800 --> 00:00:05.200
for everything happening above our heads and beyond.
2
00:00:05.440 --> 00:00:08.200
I'm Anna and I'm thrilled to be your host as we
3
00:00:08.200 --> 00:00:11.160
explore the universe together. Today we've got a fascinating
4
00:00:11.160 --> 00:00:14.040
lineup of stories from the forefront of space exploration and
5
00:00:14.040 --> 00:00:16.760
astronomy. We'll be diving into some recent
6
00:00:16.760 --> 00:00:19.720
incidents, including a significant test anomaly
7
00:00:19.720 --> 00:00:22.320
for a key component of NASA's Space Launch System
8
00:00:22.640 --> 00:00:25.160
and the surprising legal challenges facing
9
00:00:25.160 --> 00:00:27.520
SpaceX over a Starship explosion.
10
00:00:28.350 --> 00:00:31.150
But it's not all about the dramatic events. We
11
00:00:31.150 --> 00:00:33.790
also have some truly captivating science to share,
12
00:00:34.270 --> 00:00:37.190
like the rare daytime fireball that may have impacted a
13
00:00:37.190 --> 00:00:40.110
home in Georgia and groundbreaking new research
14
00:00:40.270 --> 00:00:43.070
that might finally explain the mysterious differences
15
00:00:43.390 --> 00:00:46.030
between the near and far sides of our own
16
00:00:46.030 --> 00:00:48.430
moon. And for something a little different,
17
00:00:48.670 --> 00:00:51.430
we'll journey back in time to uncover the incredible
18
00:00:51.430 --> 00:00:54.350
true story of a con man who managed to fool
19
00:00:54.350 --> 00:00:55.710
the world as an astronaut.
20
00:00:55.870 --> 00:00:58.870
So settle in and let's get started on another exciting episode
21
00:00:58.870 --> 00:00:59.950
of Astronomy Daily.
22
00:01:01.690 --> 00:01:04.650
Delve into some significant news from the world of space exploration,
23
00:01:05.130 --> 00:01:07.610
specifically regarding NASA's Space Launch System,
24
00:01:07.930 --> 00:01:10.810
or SLS. On June 26,
25
00:01:10.810 --> 00:01:13.570
during a test firing in Utah, a new version of the
26
00:01:13.570 --> 00:01:16.090
solid rocket booster being developed for the SLS
27
00:01:16.170 --> 00:01:18.890
experienced an anomaly. This test was for
28
00:01:18.890 --> 00:01:21.810
Northrop Grumman's Booster Obsolescence and Life
29
00:01:21.810 --> 00:01:24.610
Extension, or bol, version of the five
30
00:01:24.610 --> 00:01:27.430
segment solid rocket booster. The booster,
31
00:01:27.430 --> 00:01:30.270
fixed horizontally, was undergoing a, uh, two minute
32
00:01:30.270 --> 00:01:33.190
firing simulating a real launch. A little over
33
00:01:33.190 --> 00:01:36.030
100 seconds into the test, observers noted exhaust
34
00:01:36.030 --> 00:01:38.990
appearing from the side of the nozzle, followed by debris
35
00:01:38.990 --> 00:01:41.670
scattering from that same area. Despite
36
00:01:41.670 --> 00:01:44.630
this, the motor continued to burn for the rest of
37
00:01:44.630 --> 00:01:47.310
the test. Initially, NASA and
38
00:01:47.310 --> 00:01:50.190
Northrop Grumman officials didn't publicly address the
39
00:01:50.190 --> 00:01:52.640
incident during their webcast. However,
40
00:01:53.040 --> 00:01:55.760
a few hours later, Jim Calborer,
41
00:01:55.920 --> 00:01:58.560
vice president of Propulsion systems at Northrop
42
00:01:58.560 --> 00:02:00.920
Grumman, released a statement confirming the
43
00:02:00.920 --> 00:02:03.840
anomaly. He noted that while the motor seemed
44
00:02:03.840 --> 00:02:06.720
to perform well through a harsh burn environment, the
45
00:02:06.720 --> 00:02:09.680
issue occurred near the end of the burn. Kalberer
46
00:02:09.680 --> 00:02:12.440
added that the company was pushing the boundaries of
47
00:02:12.440 --> 00:02:15.400
large solid rocket motor design and
48
00:02:15.400 --> 00:02:18.240
that this new, largest ever segmented
49
00:02:18.240 --> 00:02:21.090
solid rocket booster test provides valuable
50
00:02:21.090 --> 00:02:23.810
data for future developments. The
51
00:02:23.810 --> 00:02:26.570
bowl design is intended to be used for SLS
52
00:02:26.570 --> 00:02:29.530
missions starting with Artemis 9, projected for the
53
00:02:29.530 --> 00:02:32.530
2000-30s. Its key improvements include replacing
54
00:02:32.530 --> 00:02:35.410
the shuttle era steel casings with new carbon
55
00:02:35.410 --> 00:02:38.410
fibre composite designs using a uh, new propellant
56
00:02:38.410 --> 00:02:41.210
formulation and incorporating other advancements that
57
00:02:41.210 --> 00:02:44.130
boost its performance by over 10%. This
58
00:02:44.130 --> 00:02:46.770
would allow an additional 5 metric tonnes of payload for
59
00:02:46.770 --> 00:02:48.730
SLS missions heading to the moon.
60
00:02:49.730 --> 00:02:52.450
However, there's a degree of uncertainty about whether the bowl design
61
00:02:52.450 --> 00:02:55.450
will actually fly. NASA's fiscal year
62
00:02:55.450 --> 00:02:58.090
2026 budget proposal aims to cancel the
63
00:02:58.090 --> 00:03:00.370
SLS after the Artemis 3 mission.
64
00:03:01.090 --> 00:03:03.890
While a provision in the Senate's budget reconciliation bill
65
00:03:03.890 --> 00:03:06.610
could add funding for two more SLS missions
66
00:03:06.850 --> 00:03:09.850
through Artemis V, it doesn't clarify the vehicle's
67
00:03:09.850 --> 00:03:12.370
future beyond that. Interestingly,
68
00:03:12.770 --> 00:03:15.530
this isn't the first time a Northrop Grumman solid
69
00:03:15.530 --> 00:03:18.490
rocket booster has faced a nozzle issue in less than a
70
00:03:18.490 --> 00:03:21.050
year. Back in October 2024,
71
00:03:21.370 --> 00:03:23.850
a nozzle detached from one of the much smaller
72
00:03:23.850 --> 00:03:26.730
GEM3.6XL solid rocket boosters
73
00:03:26.970 --> 00:03:29.770
on the second launch of United Launch Alliance's Vulcan
74
00:03:29.770 --> 00:03:32.730
rocket. While that issue did degrade the booster's performance
75
00:03:32.810 --> 00:03:35.210
somewhat, it didn't prevent Vulcan from
76
00:03:35.210 --> 00:03:37.970
successfully completing its mission. ULA
77
00:03:37.970 --> 00:03:40.930
later confirmed in March that a manufacturing defect in
78
00:03:40.930 --> 00:03:43.890
one of the internal parts of the nozzle caused it to
79
00:03:43.890 --> 00:03:46.610
come off, and fixes to correct this problem
80
00:03:47.010 --> 00:03:49.570
were successfully confirmed in a test
81
00:03:49.570 --> 00:03:52.530
firing in February. These
82
00:03:52.530 --> 00:03:55.450
incidents highlight the complex and challenging
83
00:03:55.450 --> 00:03:57.850
nature of developing such powerful
84
00:03:57.850 --> 00:03:59.170
propulsion systems.
85
00:04:00.609 --> 00:04:03.290
Now let's turn our gaze from man made rockets to a natural
86
00:04:03.290 --> 00:04:06.250
phenomenon that recently put on quite a show. A large
87
00:04:06.250 --> 00:04:09.130
meteor created a spectacular, rare daytime fireball
88
00:04:09.130 --> 00:04:11.860
over the southeastern United States on a Friday at
89
00:04:11.860 --> 00:04:14.660
12:25pm Eastern Daylight Time. This
90
00:04:14.660 --> 00:04:17.460
wasn't just any meteor. It was so bright that it was
91
00:04:17.460 --> 00:04:20.260
even seen by the National oceanic and Atmospheric
92
00:04:20.260 --> 00:04:22.820
Administration's GOES 19 Earth observation
93
00:04:22.820 --> 00:04:25.420
satellite, using an instrument designed to map
94
00:04:25.420 --> 00:04:28.020
flashes of lightning from orbit. Daylight
95
00:04:28.020 --> 00:04:30.940
fireballs are truly uncommon, according to Robert
96
00:04:30.940 --> 00:04:33.700
Lunsford of the American Meteor Association. It
97
00:04:33.700 --> 00:04:36.660
takes a significantly large object, much bigger
98
00:04:36.660 --> 00:04:39.530
than your average pea sized meteor, to be bright enough to
99
00:04:39.530 --> 00:04:42.530
be visible during the day. He notes that we probably only
100
00:04:42.530 --> 00:04:45.450
see about one per month worldwide, meaning only about
101
00:04:45.450 --> 00:04:48.410
one in every 3,000 meteor reports occurs during
102
00:04:48.410 --> 00:04:51.370
daylight hours. This particular meteor was
103
00:04:51.370 --> 00:04:54.050
first spotted approximately 48 miles above Oxford,
104
00:04:54.050 --> 00:04:56.730
Georgia, hurtling through the atmosphere at around
105
00:04:56.730 --> 00:04:59.730
30,000 miles per hour. Experts
106
00:04:59.730 --> 00:05:02.370
suggest it might have been associated with the daytime
107
00:05:02.370 --> 00:05:05.290
Beta Taurid shower, which peaks in late June as
108
00:05:05.290 --> 00:05:08.130
Earth passes through debris from the ancient comet 2P
109
00:05:08.370 --> 00:05:11.170
Enker. What makes this event even more
110
00:05:11.170 --> 00:05:14.090
intriguing is the strong possibility that fragments of
111
00:05:14.090 --> 00:05:17.050
the meteor survived its fiery descent and
112
00:05:17.130 --> 00:05:20.010
impacted the ground. In the hours following
113
00:05:20.010 --> 00:05:22.650
the fireball, photos began circulating online,
114
00:05:23.210 --> 00:05:26.010
purportedly showing a hole punched through the roof of a home
115
00:05:26.010 --> 00:05:28.730
in Henry County, Georgia. The size of this
116
00:05:28.730 --> 00:05:31.610
meteor meant it had a better chance of producing fragments.
117
00:05:32.090 --> 00:05:34.770
Scientists look for reports of sounds like thunder
118
00:05:34.770 --> 00:05:37.700
or something, sonic booms, which indicate that parts of
119
00:05:37.700 --> 00:05:40.580
the fireball made it down to the lower atmosphere
120
00:05:40.740 --> 00:05:43.060
and potentially all the way to the ground.
121
00:05:43.940 --> 00:05:46.900
This strongly suggests the photograph of the hole in the roof
122
00:05:47.060 --> 00:05:49.460
is indeed connected to this celestial
123
00:05:49.460 --> 00:05:52.420
visitor. And if verified, it wouldn't
124
00:05:52.420 --> 00:05:55.140
be the first time a daytime Beta Taurid left its mark.
125
00:05:55.940 --> 00:05:58.580
Lunsford mentioned a particularly large meteor
126
00:05:58.820 --> 00:06:01.650
believed to be linked to this annual shower that
127
00:06:01.650 --> 00:06:04.610
detonated in a powerful air burst just six miles
128
00:06:04.610 --> 00:06:07.570
over Russian Siberia in June 1908.
129
00:06:07.890 --> 00:06:10.610
That explosion, known as the Tunguska Event,
130
00:06:10.930 --> 00:06:13.610
ignited massive forest fires and flattened an
131
00:06:13.610 --> 00:06:16.330
estimated 80 million trees. It's a
132
00:06:16.330 --> 00:06:19.210
powerful reminder of the impact these space rocks can
133
00:06:19.210 --> 00:06:22.010
have even when they don't directly hit the
134
00:06:22.010 --> 00:06:24.610
surface from natural
135
00:06:24.610 --> 00:06:25.170
impacts.
136
00:06:25.330 --> 00:06:27.970
We now shift our focus to human made space endeavours.
137
00:06:28.490 --> 00:06:31.130
Specifically, the latest legal challenges faced by
138
00:06:31.130 --> 00:06:33.690
SpaceX. The Mexican president,
139
00:06:33.690 --> 00:06:36.610
Claudia Sheinbaum, has recently threatened to file
140
00:06:36.610 --> 00:06:39.370
a lawsuit against SpaceX, citing alleged
141
00:06:39.370 --> 00:06:42.290
contamination resulting from a starship explosion that
142
00:06:42.290 --> 00:06:45.290
occurred earlier this month. On June 18,
143
00:06:45.530 --> 00:06:48.450
SpaceX was conducting a test of the upper stage of
144
00:06:48.450 --> 00:06:51.330
its starship vehicle at its Starbase facility near
145
00:06:51.330 --> 00:06:54.300
Boca Chica beach in Texas. This test
146
00:06:54.300 --> 00:06:56.900
culminated in a dramatic fireball. While
147
00:06:56.900 --> 00:06:59.820
SpaceX stated on social media that there were no hazards to
148
00:06:59.820 --> 00:07:02.540
the surrounding communities, President Sheinbaum is
149
00:07:02.540 --> 00:07:05.140
contesting that claim. During a press
150
00:07:05.140 --> 00:07:08.020
conference, she indicated that a general review
151
00:07:08.020 --> 00:07:10.860
is underway of the international laws that are
152
00:07:10.860 --> 00:07:13.500
being violated. Specifically due to this
153
00:07:13.500 --> 00:07:16.380
perceived contamination, the Mexican
154
00:07:16.380 --> 00:07:19.140
government is looking to file the necessary lawsuits.
155
00:07:19.870 --> 00:07:22.270
It's worth noting the geographical context here.
156
00:07:22.910 --> 00:07:25.830
SpaceX's Starbase facility is located at the
157
00:07:25.830 --> 00:07:28.710
very southeastern tip of Texas, right along the
158
00:07:28.710 --> 00:07:31.670
Rio Grande river, which acts as the border between the
159
00:07:31.670 --> 00:07:34.630
United States and Mexico. Just across this border
160
00:07:34.630 --> 00:07:37.590
from Boca Chica and nearby Brownsville, Texas, lies the
161
00:07:37.590 --> 00:07:39.710
Mexican city of Heroica Matamoros.
162
00:07:40.590 --> 00:07:43.590
This isn't the first time SpaceX has faced environmental
163
00:07:43.590 --> 00:07:46.230
lawsuits or other legal challenges. In
164
00:07:46.230 --> 00:07:48.990
2023, a coalition of environmental
165
00:07:48.990 --> 00:07:51.830
groups sued the US Federal Aviation Administration,
166
00:07:52.390 --> 00:07:55.310
alleging that the agency hadn't properly analysed
167
00:07:55.310 --> 00:07:58.310
the potential damage Starship could inflict on the surrounding areas,
168
00:07:58.550 --> 00:08:00.870
which are, uh, home to protected bird species.
169
00:08:01.589 --> 00:08:04.190
More recently, in 2024, the
170
00:08:04.190 --> 00:08:07.030
Texas Commission on Environmental Quality reported that
171
00:08:07.030 --> 00:08:09.670
SpaceX had violated the Clean Water act by
172
00:08:09.670 --> 00:08:12.070
releasing pollutants into nearby bodies of water.
173
00:08:12.590 --> 00:08:14.830
Though SpaceX refuted these claims as
174
00:08:14.990 --> 00:08:17.590
factually inaccurate, past
175
00:08:17.590 --> 00:08:20.110
starship launches, and particularly explosions,
176
00:08:20.430 --> 00:08:23.430
have indeed left significant amounts of debris scattered across
177
00:08:23.430 --> 00:08:26.150
Boca Chica beach and its environs. The
178
00:08:26.150 --> 00:08:29.150
debut flight of Starship on April 20, 2023,
179
00:08:29.310 --> 00:08:32.030
saw the rocket's 33 first stage Raptor
180
00:08:32.030 --> 00:08:34.990
engines propel chunks of cement and other debris for
181
00:08:34.990 --> 00:08:37.750
miles. Local residents describe that launch
182
00:08:37.750 --> 00:08:40.540
as terrifying and likened it to an earthquake,
183
00:08:40.620 --> 00:08:42.940
with debris even crushing a nearby car.
184
00:08:43.500 --> 00:08:46.060
That flight also ended dramatically when SpaceX
185
00:08:46.060 --> 00:08:48.700
initiated its onboard flight termination system,
186
00:08:49.100 --> 00:08:52.060
causing the vehicle to explode about three minutes after
187
00:08:52.060 --> 00:08:55.019
liftoff, with fragments found along the shores.
188
00:08:55.019 --> 00:08:57.540
In the days that followed. To date,
189
00:08:57.540 --> 00:09:00.540
Starship's upper stage has exploded or crashed into
190
00:09:00.540 --> 00:09:02.940
the sea on eight of its nine test flights.
191
00:09:03.260 --> 00:09:05.900
Underscoring the experimental nature of these ambitious
192
00:09:05.900 --> 00:09:08.460
endeavours, these incidents highlight the
193
00:09:08.460 --> 00:09:10.940
ongoing environmental considerations as, uh, space
194
00:09:10.940 --> 00:09:13.380
exploration continues to push boundaries
195
00:09:14.660 --> 00:09:17.460
from the complexities of earthly legal battles in space.
196
00:09:17.860 --> 00:09:20.740
We now pivot to the ancient mysteries of our Moon,
197
00:09:21.140 --> 00:09:23.900
specifically the enduring puzzle of why its near
198
00:09:23.900 --> 00:09:26.860
side looks so different from its far side. For
199
00:09:26.860 --> 00:09:29.740
a long time, this was one of the Moon's most intriguing
200
00:09:29.740 --> 00:09:32.260
secrets. Until 1959,
201
00:09:32.720 --> 00:09:35.520
when the USSR's Luna 3 spacecraft first
202
00:09:35.520 --> 00:09:38.120
circled the Moon and sent back grainy black and white
203
00:09:38.120 --> 00:09:40.920
images, humans had never actually seen the lunar
204
00:09:40.920 --> 00:09:43.800
far side. What those images revealed was a stark
205
00:09:43.800 --> 00:09:46.800
contrast. The far side was heavily cratered, with
206
00:09:46.800 --> 00:09:49.600
far fewer of the dark volcanic plains known as
207
00:09:49.600 --> 00:09:52.480
maria that so distinctly mark the near side.
208
00:09:53.280 --> 00:09:56.200
This immediate visual difference prompted many questions
209
00:09:56.200 --> 00:09:58.930
about the Moon's formation and evolution. Was
210
00:09:58.930 --> 00:10:01.890
Earth's gravitational pull responsible? Or perhaps
211
00:10:01.890 --> 00:10:04.690
a difference in crustal thickness? Scientists
212
00:10:04.690 --> 00:10:07.610
realised the Moon wasn't a uniform body and the search
213
00:10:07.610 --> 00:10:09.570
for answers has continued ever since.
214
00:10:10.530 --> 00:10:12.970
Now, new research published in Nature
215
00:10:12.970 --> 00:10:15.450
Communications, led by Ji Jun Jing from
216
00:10:15.450 --> 00:10:18.170
Ihime University in Japan, offers a
217
00:10:18.170 --> 00:10:21.130
compelling explanation that points to trace amounts of certain
218
00:10:21.130 --> 00:10:24.010
minerals. The study focuses on chlorine and
219
00:10:24.010 --> 00:10:26.850
fluorine and their presence in lunar minerals and melts.
220
00:10:27.650 --> 00:10:30.130
It highlights that most near side lunar crust
221
00:10:30.130 --> 00:10:32.570
materials show an unusual enrichment in
222
00:10:32.570 --> 00:10:35.570
chlorine, a ah finding that doesn't quite fit with traditional
223
00:10:35.570 --> 00:10:38.490
models of primary crust formation. This anomaly,
224
00:10:38.490 --> 00:10:41.370
the researchers suggest, is likely due to a process
225
00:10:41.370 --> 00:10:42.770
called metasomatism.
226
00:10:43.490 --> 00:10:46.250
Metasomatism is a geological process where a
227
00:10:46.250 --> 00:10:48.930
rock's chemical composition is altered when new
228
00:10:48.930 --> 00:10:51.690
chemical elements are introduced, often by water or
229
00:10:51.690 --> 00:10:54.680
magma. M In the lunar context, the research
230
00:10:54.760 --> 00:10:57.320
indicates that gaseous chlorine compounds
231
00:10:57.480 --> 00:11:00.360
found their way into near side lunar rocks through this
232
00:11:00.360 --> 00:11:03.240
process, while farside samples don't show the same
233
00:11:03.240 --> 00:11:05.920
enrichment. Another key piece of this
234
00:11:05.920 --> 00:11:08.360
lunar puzzle is what's known as the Moon's creep
235
00:11:08.360 --> 00:11:11.200
terrain. This is a large region exclusively
236
00:11:11.200 --> 00:11:14.040
found on the Moon's near side, characterised by high
237
00:11:14.040 --> 00:11:17.000
concentrations of potassium, rare earth elements
238
00:11:17.080 --> 00:11:19.970
and phosphorus, hence the acronym
239
00:11:19.970 --> 00:11:22.450
creep. It's also known for its significant
240
00:11:22.610 --> 00:11:25.410
thorium concentrations. Creep is
241
00:11:25.410 --> 00:11:28.130
crucial to Understanding the moon's early evolution after its
242
00:11:28.130 --> 00:11:31.130
global magma ocean phase. While creep was
243
00:11:31.130 --> 00:11:34.050
likely widespread initially, it's now confined to this
244
00:11:34.050 --> 00:11:36.850
one region, possibly due to the massive impact
245
00:11:37.010 --> 00:11:40.010
that created the south pole Aitken Basin on the
246
00:11:40.010 --> 00:11:42.970
opposite side of the Moon. That impact might
247
00:11:42.970 --> 00:11:45.720
have generated a thermal anomaly and that drove the
248
00:11:45.720 --> 00:11:48.640
creep towards the near side. The new
249
00:11:48.640 --> 00:11:51.240
research suggests a strong connection between widespread
250
00:11:51.240 --> 00:11:54.160
chlorine vapour on the lunar near side and
251
00:11:54.160 --> 00:11:57.040
this lunar dichotomy. They hypothesise that
252
00:11:57.040 --> 00:11:59.960
this chlorine metasomatism is likely related to
253
00:11:59.960 --> 00:12:02.840
degassing caused by impacts or eruptions from the creep
254
00:12:02.840 --> 00:12:05.360
terrain. Chlorine is highly volatile and
255
00:12:05.360 --> 00:12:08.240
incompatible, meaning it doesn't easily fit into the
256
00:12:08.240 --> 00:12:10.640
crystal structure of minerals. As magma cools,
257
00:12:11.220 --> 00:12:14.140
so chlorine rich vapours released during volcanic eruptions or
258
00:12:14.140 --> 00:12:16.940
impact induced evaporation likely played a key role in
259
00:12:16.940 --> 00:12:19.700
transforming the moon's near side, the side we see most
260
00:12:19.700 --> 00:12:22.660
clearly. Conversely, the far side, untouched
261
00:12:22.660 --> 00:12:25.620
by these vapour related volcanic activities, may be more
262
00:12:25.620 --> 00:12:28.540
pristine, preserving information from the moon's very early
263
00:12:28.540 --> 00:12:31.460
magma ocean phase. While this research
264
00:12:31.540 --> 00:12:33.820
provides a strong hypothesis for the lunar
265
00:12:33.820 --> 00:12:36.700
dichotomy, the authors emphasise that more
266
00:12:36.700 --> 00:12:39.640
evidence is needed. This is where future missions
267
00:12:39.640 --> 00:12:42.320
come in. China has already landed two
268
00:12:42.320 --> 00:12:45.080
missions on the lunar far side, including the Chang'
269
00:12:45.080 --> 00:12:47.800
E6 mission, which successfully gathered
270
00:12:47.800 --> 00:12:50.400
samples. The authors believe that
271
00:12:50.400 --> 00:12:53.160
measurements of halogens in these Farside Chang'
272
00:12:53.160 --> 00:12:55.960
E6 samples could provide the crucial evidence
273
00:12:55.960 --> 00:12:58.080
needed to strengthen their explanation.
274
00:12:58.960 --> 00:13:01.680
It's a truly exciting prospect for lunar science
275
00:13:03.120 --> 00:13:05.960
from deep space. We now turn our attention back to
276
00:13:05.960 --> 00:13:08.440
Earth, specifically to a captivating,
277
00:13:08.440 --> 00:13:11.280
unbelievable but true story of a con man
278
00:13:11.360 --> 00:13:14.200
who for a time managed to fool the world into
279
00:13:14.200 --> 00:13:15.760
believing he was an astronaut.
280
00:13:17.840 --> 00:13:20.320
A cold January evening in 1989.
281
00:13:21.200 --> 00:13:23.880
Members of the Experimental Aircraft association of
282
00:13:23.880 --> 00:13:26.400
Boston are eagerly awaiting a special guest.
283
00:13:26.720 --> 00:13:29.560
The President introduces him as a master of the
284
00:13:29.560 --> 00:13:32.320
skies and space. Onto the stage
285
00:13:32.400 --> 00:13:34.960
strides US Marine Captain Robert J. Hunt,
286
00:13:35.280 --> 00:13:38.040
27 years old, handsome, with a confident
287
00:13:38.040 --> 00:13:41.040
air and dressed in a powder blue NASA flight suit
288
00:13:41.040 --> 00:13:43.920
complete with shining space patches. Hunt
289
00:13:43.920 --> 00:13:46.920
captivated the amateur pilots with fantastic tales of
290
00:13:46.920 --> 00:13:49.400
his life as a Marine fighter pilot bombing
291
00:13:49.400 --> 00:13:52.000
Gaddafi's Libya from his F A18 jet.
292
00:13:52.480 --> 00:13:55.000
But his most astonishing claims involved
293
00:13:55.000 --> 00:13:58.000
soaring above Earth aboard the space shuttle Atlantis
294
00:13:58.080 --> 00:14:00.720
on top secret missions for the Department of Defence.
295
00:14:01.520 --> 00:14:04.360
He even presented two blackened tiles which he
296
00:14:04.360 --> 00:14:07.120
claimed were scorched during his re entry. Despite
297
00:14:07.120 --> 00:14:10.080
some members suspicions like Joy Alexander, who found
298
00:14:10.240 --> 00:14:12.760
his thick New England accent and rude attitude
299
00:14:12.760 --> 00:14:15.480
unsettling for a NASA astronaut, most were
300
00:14:15.480 --> 00:14:18.400
spellbound. Hunt shook hands, scribbled autographs
301
00:14:18.400 --> 00:14:21.080
and left the aviation enthusiasts believing they had met a
302
00:14:21.080 --> 00:14:24.000
legend. But Robert J Hunt had never been
303
00:14:24.000 --> 00:14:27.000
to space. He didn't even have a pilot's licence, let
304
00:14:27.000 --> 00:14:29.750
alone a driver's licence. He was an imposter,
305
00:14:29.750 --> 00:14:32.110
and his incredible scam would soon make national
306
00:14:32.110 --> 00:14:35.030
headlines, leading to his arrest in less than a
307
00:14:35.030 --> 00:14:37.990
week. Hunt had been leading law enforcement on a cat
308
00:14:37.990 --> 00:14:40.910
and mouse chase for years, posing as a Marine,
309
00:14:41.230 --> 00:14:43.910
a baseball star, a senator and other prominent
310
00:14:43.910 --> 00:14:46.870
figures often escaping prosecution. It was
311
00:14:46.870 --> 00:14:49.390
only when he became an astronaut that he triggered a security
312
00:14:49.470 --> 00:14:51.790
panic, embarrassed politicians and
313
00:14:51.790 --> 00:14:54.720
captivated the nation. Hunt's obsession
314
00:14:54.720 --> 00:14:57.600
with space began at age 7. Watching the
315
00:14:57.600 --> 00:15:00.240
Apollo 11 moon landing. He felt a deep
316
00:15:00.240 --> 00:15:02.880
connection to astronauts like Neil Armstrong and Alan
317
00:15:02.880 --> 00:15:05.600
Shepard. As a teenager, he would sneak into
318
00:15:05.600 --> 00:15:08.600
Chelsea Naval Hospital, slip on discarded uniforms
319
00:15:08.760 --> 00:15:11.440
and salute himself in the mirror, dreaming of
320
00:15:11.440 --> 00:15:14.160
exploring distant planets. His
321
00:15:14.160 --> 00:15:16.840
father, Leo Hunt, a plumber who also
322
00:15:16.840 --> 00:15:19.600
pretended to be a military colonel, unknowingly
323
00:15:19.600 --> 00:15:22.460
influenced him and even writing a book about his alleged
324
00:15:22.460 --> 00:15:24.940
life in the military titled Colonel Chameleon.
325
00:15:25.420 --> 00:15:28.300
Robert Hunt claims his father taught him the art of deception,
326
00:15:28.300 --> 00:15:30.900
like when he sold sparrows painted yellow as
327
00:15:30.900 --> 00:15:33.660
canaries. Robert's first steps into
328
00:15:33.660 --> 00:15:36.659
grander deceptions came early. He claimed to join
329
00:15:36.659 --> 00:15:38.700
the Marine Corps on a delayed entry programme,
330
00:15:39.340 --> 00:15:41.700
was supposedly honourably discharged due to an
331
00:15:41.700 --> 00:15:44.700
administrative error, and then simply bluffed his way back into
332
00:15:44.700 --> 00:15:47.340
barracks, knowing the commands and structure.
333
00:15:47.820 --> 00:15:50.740
He even snuck onto Pease Air Force Base dressed as a
334
00:15:50.740 --> 00:15:53.460
second lieutenant, and was caught poking around Air Force
335
00:15:53.460 --> 00:15:56.460
Two, the Vice President's plane. This
336
00:15:56.460 --> 00:15:59.380
incident triggered an FBI investigation and ended his
337
00:15:59.380 --> 00:16:01.660
first marriage. His cons
338
00:16:01.740 --> 00:16:04.740
escalated. He married again, claiming to be
339
00:16:04.740 --> 00:16:07.580
a college graduate with a baseball contract. He
340
00:16:07.580 --> 00:16:10.580
even invented a spray on diaper cream called Love My
341
00:16:10.580 --> 00:16:13.220
Baby, falsely claiming a multi million dollar
342
00:16:13.220 --> 00:16:16.090
buyout was imminent. Using his wife's credit
343
00:16:16.090 --> 00:16:18.730
card, he rented limos and posed as a TV
344
00:16:18.730 --> 00:16:21.730
producer to cast a Super bowl commercial, only to be
345
00:16:21.730 --> 00:16:24.650
busted by police, who described him as a smooth talker.
346
00:16:25.370 --> 00:16:28.010
After these setbacks, Hunt fled back to the
347
00:16:28.010 --> 00:16:30.770
military, using fake credentials to acquire flight
348
00:16:30.770 --> 00:16:33.730
uniforms and promoting himself from marine pilot to Captain
349
00:16:33.730 --> 00:16:36.410
Hunt, America's youngest Marine astronaut,
350
00:16:36.570 --> 00:16:39.130
complete with $20 Navy astronaut wings.
351
00:16:39.370 --> 00:16:42.250
He claimed to have bluffed his way into NASA astronaut
352
00:16:42.250 --> 00:16:44.830
training, undergoing physical evaluations at
353
00:16:44.830 --> 00:16:47.710
Johnson Space Centre and studying in Rocket City,
354
00:16:47.710 --> 00:16:50.630
Huntsville, Alabama. He even said he spent
355
00:16:50.710 --> 00:16:53.590
nine weeks with Morton Thiokol, the company that
356
00:16:53.590 --> 00:16:56.470
built solid rocket boosters. While none of
357
00:16:56.470 --> 00:16:59.150
these claims are verified, Hunt's narrative was
358
00:16:59.150 --> 00:17:01.990
detailed enough to convince many, including his fourth
359
00:17:01.990 --> 00:17:04.710
wife, Ann Sweeney, an optical engineer.
360
00:17:05.030 --> 00:17:07.790
He whisked her away on private jets and exotic
361
00:17:07.790 --> 00:17:10.619
vacations, paying with her corporate credit card.
362
00:17:11.179 --> 00:17:14.019
The pinnacle of his astronaut hoax came in December
363
00:17:14.019 --> 00:17:16.899
1988 when he travelled to Ireland to visit
364
00:17:16.899 --> 00:17:19.899
his brother in law on the Aer Lingus flight.
365
00:17:19.899 --> 00:17:22.539
He charmed the crew and was invited into the cockpit.
366
00:17:22.699 --> 00:17:25.339
Upon landing in Dublin, he was shocked to be greeted by
367
00:17:25.339 --> 00:17:27.979
smiling Irish government officials and a small
368
00:17:27.979 --> 00:17:30.819
band playing the national anthem. He didn't even go
369
00:17:30.819 --> 00:17:33.259
through customs. Hunt played along,
370
00:17:33.499 --> 00:17:36.130
giving speeches, accepting awards and
371
00:17:36.130 --> 00:17:39.050
sipping tea with Dublin's Lord Mayor, Ben Briscoe,
372
00:17:39.210 --> 00:17:41.930
who, despite his suspicions, politely let the spectacle
373
00:17:41.930 --> 00:17:44.850
continue. Hunt left Ireland with souvenirs
374
00:17:44.850 --> 00:17:47.810
and honorary Irish citizenship, claiming it
375
00:17:47.810 --> 00:17:50.529
all just got out of control. Back in the
376
00:17:50.529 --> 00:17:52.650
US his scheme began to unravel.
377
00:17:53.450 --> 00:17:56.450
American Express rejected a $5,000 charge for the
378
00:17:56.450 --> 00:17:58.970
private jet trip, alerting his wife's employer,
379
00:17:58.970 --> 00:18:01.700
Polaroid. Massachusetts State Trooper
380
00:18:01.700 --> 00:18:04.180
Andrew Palombo began investigating Hunt
381
00:18:04.420 --> 00:18:07.260
after a woman complained he had convinced her son to
382
00:18:07.260 --> 00:18:10.140
enlist, then demanded $4,000
383
00:18:10.140 --> 00:18:13.060
to use his Pentagon connections for a discharge.
384
00:18:13.620 --> 00:18:16.620
Palombo, a diligent and tough investigator,
385
00:18:16.620 --> 00:18:19.420
quickly discovered Hunt's military records showed only
386
00:18:19.420 --> 00:18:21.820
two months in the Marine Reserve, ending with a
387
00:18:21.820 --> 00:18:24.740
psychological evaluation. On January
388
00:18:24.820 --> 00:18:27.750
28, 1989, Palambo knocked on
389
00:18:27.750 --> 00:18:30.750
Hunt's door. A search of his home revealed military
390
00:18:30.750 --> 00:18:33.430
paraphernalia, flight jumpsuits, a NASA
391
00:18:33.430 --> 00:18:36.350
helmet, police badges and photos of Hunt wearing Korean War
392
00:18:36.350 --> 00:18:39.150
medals. His wife, Ann Sweeney, surrendered two
393
00:18:39.150 --> 00:18:42.150
scorched space shuttle tiles, which Palambo identified
394
00:18:42.150 --> 00:18:45.110
as ordinary floor tiles. Hunt was arrested for
395
00:18:45.110 --> 00:18:47.910
larceny. Palambo was relentless, discovering a
396
00:18:47.910 --> 00:18:50.670
fake doctor's ID and confirming that Hunt's military
397
00:18:50.670 --> 00:18:52.590
uniforms were acquired fraudulently.
398
00:18:53.510 --> 00:18:56.150
NASA and FBI determined that impersonating an
399
00:18:56.150 --> 00:18:59.030
astronaut wasn't illegal unless other crimes were involved.
400
00:18:59.110 --> 00:19:02.110
But Palambo logged Hunt's astronaut gear as evidence of
401
00:19:02.110 --> 00:19:04.990
his fraud. Ann Sweeney was devastated to
402
00:19:04.990 --> 00:19:07.990
learn her husband was a con man. It was almost like watching
403
00:19:07.990 --> 00:19:10.950
someone die, she told the Herald. Here was this
404
00:19:10.950 --> 00:19:13.750
person I thought I knew. And bit by bit, in the course of an
405
00:19:13.750 --> 00:19:16.550
hour, he just dissolved, just disappeared.
406
00:19:17.270 --> 00:19:20.070
She realised she had fallen victim to the ostrich effect,
407
00:19:20.560 --> 00:19:23.240
a psychological phenomenon where people bury their heads in the
408
00:19:23.240 --> 00:19:25.840
sand, operating under a truth bias,
409
00:19:26.240 --> 00:19:29.240
assuming others are honest. Hunt pleaded
410
00:19:29.240 --> 00:19:32.240
guilty to larceny and received a two year suspended sentence.
411
00:19:32.720 --> 00:19:35.720
After his release. In May 1989, he announced his
412
00:19:35.720 --> 00:19:38.480
candidacy for mayor of Revere, Massachusetts. But
413
00:19:38.480 --> 00:19:40.800
Trooper Palambo continued to pursue him.
414
00:19:41.200 --> 00:19:44.000
Hunt failed to pay restitution and skipped town, becoming a
415
00:19:44.000 --> 00:19:47.000
fugitive. Television crews interviewed his former wives who
416
00:19:47.000 --> 00:19:49.950
compared notes on set. His cons continued, leading him
417
00:19:49.950 --> 00:19:52.830
to pose as the head of Seal Team 6 at a US military
418
00:19:52.830 --> 00:19:55.470
base in San Francisco. There, he even
419
00:19:55.470 --> 00:19:57.950
berated an elderly man who questioned his authority,
420
00:19:58.350 --> 00:20:01.270
only to later realise it was Apollo astronaut Eugene
421
00:20:01.270 --> 00:20:03.590
cernan. Finally, in July
422
00:20:03.590 --> 00:20:06.590
1994, he was charged with false impersonation,
423
00:20:06.670 --> 00:20:09.150
pleaded guilty and served a year in prison.
424
00:20:10.030 --> 00:20:12.910
After his release, Hunt's cons persisted, with
425
00:20:12.910 --> 00:20:15.770
Palambo doggedly pursuing him until the trooper's death. And
426
00:20:15.840 --> 00:20:18.800
in 1998, with stricter security after
427
00:20:18.800 --> 00:20:21.760
911 and the Stolen Valour act of 2005
428
00:20:21.760 --> 00:20:24.640
making it illegal to falsely claim military decorations,
429
00:20:24.960 --> 00:20:27.960
Hunt's schemes became impossible. He finally
430
00:20:27.960 --> 00:20:30.640
hung up his fake uniforms and tried to rebuild his life,
431
00:20:30.960 --> 00:20:33.920
expressing regret for the hurt he caused his ex wives.
432
00:20:34.560 --> 00:20:37.280
While he maintained some incredible claims about flying real
433
00:20:37.280 --> 00:20:39.960
fighter jets, investigations by NASA and
434
00:20:39.960 --> 00:20:42.960
military records confirmed that Robert Hunt had no
435
00:20:42.960 --> 00:20:45.040
legitimate military or astronaut service.
436
00:20:46.230 --> 00:20:49.110
Today, Robert J. Hunt lives alone in New Hampshire, working
437
00:20:49.110 --> 00:20:52.110
in Construction. At 63, he reflects on
438
00:20:52.110 --> 00:20:54.910
his past. He once said, when I'm wearing a
439
00:20:54.910 --> 00:20:57.670
blue flight suit and everybody else is wearing a grey or green
440
00:20:57.670 --> 00:21:00.430
one, you stand out. Like, this guy is the super
441
00:21:00.430 --> 00:21:03.030
guru of pilots, so they all want to be your friend
442
00:21:03.910 --> 00:21:06.790
for a brief, extraordinary moment. Like the
443
00:21:06.790 --> 00:21:09.390
sparrows he once painted yellow, Hunt's
444
00:21:09.390 --> 00:21:12.210
deceptions allowed him to truly believe he could
445
00:21:12.210 --> 00:21:13.130
touch the stars.
446
00:21:15.130 --> 00:21:18.090
And with that incredible story, we're calling time
447
00:21:18.090 --> 00:21:20.690
on today's episode of Astronomy Daily. A final
448
00:21:20.690 --> 00:21:23.570
