00:00:07.200 --> 00:00:11.119
up on Spacetime, interstellar Comet three I Atlas far more
4
00:00:11.160 --> 00:00:14.960
alien than previously thought, NASA now looking at September to
5
00:00:15.080 --> 00:00:19.120
launch its new Roman Space telescope, and the European Space

00:00:19.160 --> 00:00:23.719
Agency's new Australian Dish finally commissioned. All that and more
7
00:00:23.760 --> 00:00:26.519
coming up on Spacetime.
8
00:00:27.239 --> 00:00:36.520
Welcome to space Time with Stewart Gary.
9
00:00:46.359 --> 00:00:48.920
A new study has found that interstellar Comet three I
10
00:00:49.039 --> 00:00:52.280
outlass must have originated in a much colder star system,
11
00:00:52.359 --> 00:00:55.520
one with lower levels of radiation than our own Solar system.
12
00:00:56.039 --> 00:00:58.880
The new findings were reported in the journal Nature Astronomy,
13
00:00:59.079 --> 00:01:02.359
based on the observer that three I Atlas is remarkably
14
00:01:02.439 --> 00:01:04.840
rich in a specific type of water called heavy water,
15
00:01:05.040 --> 00:01:08.519
which contains deuterium and isotope of hydrogen that contains a
16
00:01:08.599 --> 00:01:11.599
neutron in its nucleus. Water is made up of two
17
00:01:11.680 --> 00:01:14.560
hydrogen atoms and an oxygen atom, hence its H two
18
00:01:14.599 --> 00:01:18.640
a formula. In a typical water molecule, those hydrogen atoms
19
00:01:18.680 --> 00:01:21.239
have just one proton in their nucleus, orbited by an
20
00:01:21.280 --> 00:01:24.760
electron heavy water also exists on Earth, but in much
21
00:01:24.760 --> 00:01:27.680
lower quantities than what was observed in three I Outlas.
22
00:01:28.239 --> 00:01:31.120
The Steadies, lead author that we sell as Amanzana from
23
00:01:31.120 --> 00:01:33.799
the University of Michigan, says less than a year ago
24
00:01:33.920 --> 00:01:37.239
astronomers discovered a strange comet sawing through our skies that
25
00:01:37.400 --> 00:01:40.519
was not from our Solar system. Although we still don't
26
00:01:40.599 --> 00:01:43.159
know where this object three I Outlass came from, the
27
00:01:43.239 --> 00:01:46.439
new work will reveals some fresh insights about its birthplace.
28
00:01:46.879 --> 00:01:50.159
It's only the third interstellar object ever identified in our
29
00:01:50.239 --> 00:01:54.120
Solar system, and Xanas says the new observations showed that
30
00:01:54.159 --> 00:01:56.560
the conditions which led to the formation of our Solar
31
00:01:56.560 --> 00:01:59.799
system are very different from how planetary systems evolved in
32
00:01:59.799 --> 00:02:02.959
other parts of our galaxy. The amount of deterium in
33
00:02:03.000 --> 00:02:05.599
three Eye Outlas were some thirty times higher than that
34
00:02:05.680 --> 00:02:08.319
found in any comet in our Solar system, and forty
35
00:02:08.400 --> 00:02:11.759
times the value of what have found in assertions. These
36
00:02:11.840 --> 00:02:15.080
ratios tell astronomers about the conditions that were present when
37
00:02:15.080 --> 00:02:18.319
the celestial objects formed, and it allows them to compare
38
00:02:18.360 --> 00:02:21.280
the birthplace of three our Atlas with our own Solar system.
39
00:02:21.280 --> 00:02:24.479
When planets and comets were forming. It's proof that the
40
00:02:24.520 --> 00:02:27.000
conditions that led to the creation of our Solar System
41
00:02:27.199 --> 00:02:31.759
are not ubiquitous throughout space. Manzano and colleagues use the
42
00:02:31.840 --> 00:02:36.039
DMD Observatory in Arizona and Alma the Attakama Large Millimeta
43
00:02:36.080 --> 00:02:39.199
submillimeter array radio telescope in Chile to study some of
44
00:02:39.280 --> 00:02:42.639
the earliest gases emitted by the comet, and this marked
45
00:02:42.639 --> 00:02:45.039
the first time astronomers have been able to perform this
46
00:02:45.120 --> 00:02:49.800
type of analysis on an interstellar object. Apart from three Eyealys,
47
00:02:49.840 --> 00:02:53.199
the only confirmed interstellar objects ever detected passing through our
48
00:02:53.240 --> 00:02:56.879
Solar System were one I mail Maur and two IBORISEV
49
00:02:57.599 --> 00:03:02.360
and Birth have now left. This is space time still
50
00:03:02.360 --> 00:03:05.439
to come. NASA now looking at September to launch its
51
00:03:05.479 --> 00:03:09.639
new Roman space telescope, and the European Space agencies new
52
00:03:09.680 --> 00:03:13.319
Australian Dish finally commissioned. All that and more still to
53
00:03:13.319 --> 00:03:32.719
come on space time. NASA are now targeting September as
54
00:03:32.759 --> 00:03:35.400
the likely launch date for the new Nancy Grace Roman
55
00:03:35.479 --> 00:03:39.000
Space Telescope. That's much earlier than the May twenty twenty
56
00:03:39.039 --> 00:03:42.879
seven launch date originally slated. Roman is similar to NASA's
57
00:03:42.879 --> 00:03:46.159
famous Hubble Space Telescope, but it's designed to survey far
58
00:03:46.240 --> 00:03:49.960
greater fields of the sky at once. Instead of focusing
59
00:03:50.000 --> 00:03:53.199
on detailed images of individual galaxies like Hubble, Roman will
60
00:03:53.199 --> 00:03:55.960
look at wide swathes of the cosmos, trying to answer
61
00:03:56.039 --> 00:03:59.360
questions about how dark energy in dark matter, two of
62
00:03:59.360 --> 00:04:02.759
the most Mista series subjects in science today have affected
63
00:04:02.759 --> 00:04:06.800
the universe and its evolution. The Roman Space Telescope is
64
00:04:06.960 --> 00:04:10.080
very similar to Hubble. Hubble is based on the design
65
00:04:10.199 --> 00:04:13.400
of a CIA Keyhole KH nine or more likely KH
66
00:04:13.479 --> 00:04:16.439
eleven spy satellite, but modified to look out into the
67
00:04:16.519 --> 00:04:20.560
universe rather than down under the Earth's surface. Both Hubble
68
00:04:20.639 --> 00:04:24.079
and the Keyhole KH eleven spy satellites were built by Luckheed,
69
00:04:24.720 --> 00:04:27.959
and that's where the Roman Space Telescope comes in. Back
70
00:04:28.000 --> 00:04:30.959
in twenty eleven, the CIA found they had two spare
71
00:04:31.040 --> 00:04:34.439
KH eleven Keyhole spy satellites which were now surplus to
72
00:04:34.480 --> 00:04:38.839
the requirements, having been superseded by more advanced versions. They
73
00:04:38.879 --> 00:04:41.839
were stored at a special facility at Rochester in upstate
74
00:04:41.959 --> 00:04:45.040
New York and were costing the National Reconnaissance Office money
75
00:04:45.079 --> 00:04:48.199
to keep them in their special clean room environment, and
76
00:04:48.319 --> 00:04:51.560
so they were offered to NASA for free. NASA sent
77
00:04:51.600 --> 00:04:53.720
a bunch of astronomers to check them out, and the
78
00:04:53.800 --> 00:04:57.720
scientists were amazed at their capabilities, which fire exceeded anything
79
00:04:57.759 --> 00:05:01.959
at Baarburn science budget could afford. The two Keyhole satellites
80
00:05:02.000 --> 00:05:05.160
share the same two point four meter primary mirrors Hubble,
81
00:05:05.360 --> 00:05:08.120
but the mirrors are lighter and more high tech than Hubbles,
82
00:05:08.279 --> 00:05:10.399
with a broader field of view one hundred times that
83
00:05:10.519 --> 00:05:13.519
of Hubble. They have a shorter focal length than Hubble,
84
00:05:13.639 --> 00:05:15.600
making them about a meter and a half shorter than
85
00:05:15.639 --> 00:05:18.959
the famous Space telescope, A sort of stubby Hubble, I guess.
86
00:05:19.439 --> 00:05:21.600
But it's that short of focal length, which means the
87
00:05:21.680 --> 00:05:24.879
KH elevens can image at higher resolution an area one
88
00:05:24.920 --> 00:05:28.079
hundred times bigger than Hubble's wide filled camera three, a
89
00:05:28.199 --> 00:05:31.800
visible infrared instrument that's become Hubble's most advanced and heavily
90
00:05:31.879 --> 00:05:35.720
used sensor, and by imaging areas one hundred times larger
91
00:05:35.720 --> 00:05:38.199
in a single shot, more galaxies and objects can be
92
00:05:38.199 --> 00:05:42.079
studded with a single image, Unlike Hubble. The secondary mirror
93
00:05:42.079 --> 00:05:44.920
on the KH eleven telescopes can be moved either by
94
00:05:44.959 --> 00:05:49.040
ground control or automatically using on board instruments. These can
95
00:05:49.079 --> 00:05:51.839
be used to bring an image into extremely fine focus.
96
00:05:52.439 --> 00:05:55.160
The secondary mirror is supported by six struts with servo
97
00:05:55.279 --> 00:05:58.720
motors on each. These servos can maneuver the struts to
98
00:05:58.759 --> 00:06:01.759
fine tune the secondarym in order to achieve the finest
99
00:06:01.800 --> 00:06:05.680
focus possible. Originally to be named Wide Filled Infrared Survey
100
00:06:05.720 --> 00:06:10.199
Telescope or w FIRST, ROMAN will also survey exoplanets. By
101
00:06:10.199 --> 00:06:12.680
the end of its five ye emission telescopes expected to
102
00:06:12.680 --> 00:06:16.800
amass more than twenty thousand terabytes of data. Scientists will
103
00:06:16.800 --> 00:06:18.680
be able to draw in it to identify and study
104
00:06:18.720 --> 00:06:22.560
one hundred thousand exoplanets, hundreds of millions of galaxies, billions
105
00:06:22.600 --> 00:06:25.800
of stars, and rare objects and phenomena, including some that
106
00:06:25.920 --> 00:06:30.079
astronomers have never witnessed before. The Roman Space Telescope will
107
00:06:30.160 --> 00:06:33.240
launch a board a SpaceX Falcon heavy rocket Space Launch
108
00:06:33.240 --> 00:06:36.040
Complex thirty nine A at the Kennedy Space Center in Florida.
109
00:06:36.639 --> 00:06:39.839
This report on the technology of this converted spy satellite
110
00:06:39.920 --> 00:06:41.480
from MASSERTV.
111
00:06:41.759 --> 00:06:45.160
NASA's Nancy Grace. Roman Space Telescope is designed to answer
112
00:06:45.199 --> 00:06:49.079
big questions about the universe. What is dark energy, which
113
00:06:49.079 --> 00:06:51.519
seems to be speeding up the expansion of the universe,
114
00:06:52.240 --> 00:06:55.040
how many planets exist among the stars, and what are
115
00:06:55.040 --> 00:06:59.040
they like. The Roman Space Telescope is similar to Hubble,
116
00:06:59.160 --> 00:07:03.319
but benefits from thirty years of technological development. It will
117
00:07:03.399 --> 00:07:06.360
view the sky on a scale never before accomplished from space.
118
00:07:07.759 --> 00:07:10.519
This is where Roman is closest to Hubble. It has
119
00:07:10.560 --> 00:07:13.480
the same size and type of main mirror, a two
120
00:07:13.560 --> 00:07:16.839
point four meterre precisely shaped piece of silver coated glass.
121
00:07:17.560 --> 00:07:19.920
The size of this mirror is partly how Roman matches
122
00:07:19.959 --> 00:07:23.720
Hubbles resolution. Roman's main camera is the Wide Field Instrument,
123
00:07:24.120 --> 00:07:26.480
which will take infrared pictures of the sky to study
124
00:07:26.560 --> 00:07:31.879
dark energy, observe galaxies and stars, and find exoplanets. Instead
125
00:07:31.879 --> 00:07:36.000
of Hubble's single first generation image sensor, the WFI incorporates
126
00:07:36.040 --> 00:07:39.639
eighteen third generation chips that allow it to take pictures
127
00:07:39.759 --> 00:07:43.639
capturing one hundred times greater sky area than Hubbles. Each
128
00:07:43.759 --> 00:07:47.000
three hundred megapixel image will enable scientists to study a
129
00:07:47.079 --> 00:07:51.399
large portion of the sky. At Roman's back is its
130
00:07:51.399 --> 00:07:54.839
primary means of communication with Earth, the high Gain antenna.
131
00:07:55.680 --> 00:07:58.439
This antenna will be responsible for sending nearly one point
132
00:07:58.519 --> 00:08:01.160
four terabytes of data to go round stations every day.
133
00:08:01.639 --> 00:08:04.000
That's the equivalent of four hundred and sixty hours of
134
00:08:04.040 --> 00:08:09.920
streaming video. Roman's critical systems, such as power and data handling,
135
00:08:10.360 --> 00:08:14.000
are located in six modules at the spacecraft's rear. These
136
00:08:14.040 --> 00:08:18.800
include six rotating reaction wheels that control where the spacecraft points,
137
00:08:18.839 --> 00:08:22.279
nearly one ton of propellant for larger movements, and a
138
00:08:22.360 --> 00:08:28.279
ten terabyte data recorder. Roman's other instrument is its coronagraph
139
00:08:28.319 --> 00:08:33.159
technology demonstration. A coronagraph blocks the star's light to capture
140
00:08:33.159 --> 00:08:36.480
the faint light from orbiting planets. It will be the
141
00:08:36.480 --> 00:08:39.919
first time a space telescope has used deformable mirrors to
142
00:08:40.000 --> 00:08:43.480
precisely control the incoming light and special masks to block
143
00:08:43.559 --> 00:08:47.879
only the starlight. This method will enable Roman to capture
144
00:08:47.879 --> 00:08:51.080
direct images of distant planets and even analyze the light
145
00:08:51.120 --> 00:08:54.519
that is reflected off their surfaces, allowing scientists to learn
146
00:08:54.559 --> 00:09:01.000
about their composition and atmospheres. The spacecraft's solar panels provide
147
00:09:01.039 --> 00:09:05.399
its power by converting sunlight into electricity. They also shade
148
00:09:05.399 --> 00:09:09.080
the spacecraft, helping to keep its instruments at their design temperatures.
149
00:09:09.960 --> 00:09:12.639
The solar panels will be able to provide four one
150
00:09:12.720 --> 00:09:16.720
hundred watts of power, enough to run two commercial microwave ovens.
151
00:09:18.200 --> 00:09:21.440
With all these systems working together and in partnership with
152
00:09:21.600 --> 00:09:25.879
powerful future telescopes, the Nancy Grace Roman Space Telescope will
153
00:09:25.879 --> 00:09:28.360
be able to usher in a new era of studying
154
00:09:28.399 --> 00:09:29.080
our universe.
155
00:09:31.279 --> 00:09:35.159
This is space time still to come. The European Space
156
00:09:35.200 --> 00:09:38.279
Agency is new Australian dish and later in the science
157
00:09:38.360 --> 00:09:42.000
report how climate change is affecting the health of people
158
00:09:42.000 --> 00:09:45.480
across Europe. Oh, that and more still to come on
159
00:09:45.559 --> 00:10:04.720
space time. European Space Agency has commissioned its second Australian
160
00:10:04.759 --> 00:10:08.519
Deep space communications dish at its new Nausea complex near Perth.
161
00:10:09.159 --> 00:10:13.600
The thirty five meter DSA four antenna will provide essential telemetry,
162
00:10:13.679 --> 00:10:16.919
tracking and command services to keep ease of spacecraft safely
163
00:10:16.960 --> 00:10:20.440
connected with mission managers back on Earth. The new dish
164
00:10:20.480 --> 00:10:23.960
features x K and KA banned download capabilities, as well
165
00:10:23.960 --> 00:10:26.840
as X band uplink with provision for K band plan
166
00:10:26.960 --> 00:10:31.440
for the near future. The antenna uses cryogenically cooled receivers
167
00:10:31.519 --> 00:10:34.240
operating at minus two hundred and sixty three degrees kelvin.
168
00:10:34.840 --> 00:10:37.320
By cooling the link between the physical antenna and the
169
00:10:37.360 --> 00:10:41.080
receiver to near absolute zero, background interference noise can be
170
00:10:41.159 --> 00:10:45.320
drastically reduced, thereby improving the antenna's ability that detects signals
171
00:10:45.360 --> 00:10:49.200
weaker than a whisper from billions of kilometers away. DSA
172
00:10:49.360 --> 00:10:52.559
four is also equipped with a twenty kilowatte radio transmitter.
173
00:10:53.120 --> 00:10:56.120
You see, radio waves weaken the further they travel, much
174
00:10:56.200 --> 00:10:58.879
like ripples spreading out on a pond, so signals sent
175
00:10:58.919 --> 00:11:02.879
to distant spacecraft often become extremely faint. Thanks to its
176
00:11:02.919 --> 00:11:06.559
powerful transmitter, DSA four can send commands that remain strong
177
00:11:06.600 --> 00:11:09.519
and easy for spacecraft to detect, even across the vast
178
00:11:09.600 --> 00:11:13.879
distances of the Solar System. DSA four is the newest
179
00:11:13.919 --> 00:11:17.200
member of ESA's s Track Network, a global system of
180
00:11:17.240 --> 00:11:20.360
ground stations that link satellites in orbit and beyond with
181
00:11:20.440 --> 00:11:24.879
the European Space Agency's Operations Center. They receive telemetry, a
182
00:11:24.960 --> 00:11:28.159
continuous stream of health, status and scientific data sent down
183
00:11:28.200 --> 00:11:32.720
by spacecraft. Performed tracking by precisely measuring a spacecraft's distance, velocity,
184
00:11:32.759 --> 00:11:36.559
and position using radio signals and transmit commands that control
185
00:11:36.679 --> 00:11:41.879
spacecrafts on board systems, adjusting trajectories and updating mission configurations.
186
00:11:42.480 --> 00:11:45.799
With DSA four now commissioned, the network includes four to
187
00:11:45.879 --> 00:11:49.039
thirty five meter deep space antennas and three near Earth
188
00:11:49.039 --> 00:11:53.559
stations as part of its core infrastructure. DSA four complements
189
00:11:53.679 --> 00:11:57.240
s tracks existing thirty five meter dishes, DSA one, which
190
00:11:57.240 --> 00:12:00.279
is also at New Nausea, DSA two, which is in Spain,
191
00:12:00.600 --> 00:12:04.879
and DSA three in Argentina. The other three ground stations
192
00:12:04.879 --> 00:12:07.799
in s TRAC's core network are used for tracking satellites
193
00:12:07.879 --> 00:12:10.360
or launches near Earth and use either four and a
194
00:12:10.399 --> 00:12:15.080
half or fifteen meter dishes in Caeru, French Guiana, Santa Maria, Portugal,
195
00:12:15.200 --> 00:12:19.320
and in Karuna, Sweden. After its inauguration back in October
196
00:12:19.360 --> 00:12:23.480
twenty twenty five, DSA four embarked on an intensive commissioning phase.
197
00:12:24.080 --> 00:12:27.200
This met months of fine tuning everything from the dish's
198
00:12:27.240 --> 00:12:31.000
surface to its ultra precise timing systems, combined to end
199
00:12:31.039 --> 00:12:33.720
to end testing was the first step to confirm the
200
00:12:33.720 --> 00:12:37.360
signals could pass through every component of the station. During
201
00:12:37.399 --> 00:12:40.799
this phase, engineers checked the performance of the antenna's mechanics,
202
00:12:40.960 --> 00:12:45.240
radio frequency stages, frequency and timing equipment, power systems, and
203
00:12:45.399 --> 00:12:49.320
back end modems. Once the technical checks were complete, engineering
204
00:12:49.320 --> 00:12:53.519
teams prepared the station for real life operations. They refined
205
00:12:53.519 --> 00:12:56.559
the control software and configured the ground system to work
206
00:12:56.600 --> 00:12:59.600
with the new antenna and integrated DSA four into ESA's
207
00:12:59.639 --> 00:13:03.799
schedule in network control workflows. In the final phase, teams
208
00:13:03.879 --> 00:13:07.159
track modible ISSA spacecraft to ensure they could all communicate
209
00:13:07.200 --> 00:13:10.200
with the new antenna, and Euclid was the first ESA
210
00:13:10.279 --> 00:13:14.080
spacecraft to be tracked once DSA four entered normal operations,
211
00:13:14.320 --> 00:13:17.360
marking the moment the antenna came alive as a working
212
00:13:17.480 --> 00:13:21.440
part of ESA's deep space network. Bringing a second deep
213
00:13:21.480 --> 00:13:25.399
space antenna online at the Australian site boosts issa's global coverage,
214
00:13:25.440 --> 00:13:28.799
providing greater availability and flexibility, as well as built in
215
00:13:28.840 --> 00:13:33.200
a redundancy. DSA four also brings the next generation xpand
216
00:13:33.200 --> 00:13:37.080
transmission features, which will expand the link configurations possible from
217
00:13:37.120 --> 00:13:41.279
new NAUSEA, providing capabilities and operational flexibility that are unique
218
00:13:41.320 --> 00:14:01.519
within the s TRACK network. This is Space time and
219
00:14:01.720 --> 00:14:03.440
time that to take another brief look at some of
220
00:14:03.480 --> 00:14:05.879
the other stories making news and science this week. With
221
00:14:06.039 --> 00:14:09.159
the Science Report, A new study has looked at how
222
00:14:09.200 --> 00:14:12.679
climate change is affecting the health of the people of Europe.
223
00:14:13.039 --> 00:14:15.840
The findings, reported in the lands At Medical Journal, found
224
00:14:15.919 --> 00:14:19.679
key issues have seen increases since the nineteen nineties including
225
00:14:19.679 --> 00:14:22.200
an increased length in the pollen season by between one
226
00:14:22.200 --> 00:14:25.399
and two weeks, a rise in heat related deaths, an
227
00:14:25.399 --> 00:14:28.759
increase in infectious diseases such as dengy fever, which is
228
00:14:28.799 --> 00:14:31.320
now spreading more easily thanks to the hotter weather, and
229
00:14:31.519 --> 00:14:36.039
increasing food insecurity linked to heat waves, especially among poorer Europeans.
230
00:14:36.639 --> 00:14:39.480
They also found deaths from breathing in polluted air from
231
00:14:39.519 --> 00:14:42.519
woodsmirk at home rose by four percent between the year
232
00:14:42.559 --> 00:14:46.759
twoenty and twenty twenty two. The finding show climate change
233
00:14:46.799 --> 00:14:49.399
is already harming people self in Europe, and the authors
234
00:14:49.480 --> 00:14:54.120
warned that these impacts will only get worse. A new
235
00:14:54.159 --> 00:14:57.879
study warns that agricultural soils exposed to glyphis sate might
236
00:14:57.919 --> 00:15:01.879
become breeding grounds for hospital grades superbugs. A report in
237
00:15:01.879 --> 00:15:06.440
the General Frontiers in Microbiology examined ninety eight bacterial strains
238
00:15:06.480 --> 00:15:10.240
from nature reserving buenas areas located near agricultural areas where
239
00:15:10.279 --> 00:15:14.480
glyphiscate is often used. They then tested these bugs against
240
00:15:14.519 --> 00:15:19.480
sixteen common antibiotics, finding significant resistance build up. The authors
241
00:15:19.480 --> 00:15:22.720
warned that antibiotic resistant bacteria could be entering the soil
242
00:15:22.759 --> 00:15:26.240
through untreated wastewater from hospitals, but may also find their
243
00:15:26.240 --> 00:15:29.759
way back to hospitals from soil through other environmental pathways.
