Crew-12 Spy Scandal, AI on Mars & Interstellar Comet's Last Secret?
Four astronauts are stuck in quarantine in Florida as weather keeps pushing back the Crew-12 launch — now targeting no earlier than Friday, February 13. We've got the full story, including the remarkable subplot involving a Russian cosmonaut who was quietly removed from the mission in December. Plus: interstellar comet 3I/ATLAS is on its way out of the solar system forever, but new data from NASA's SPHEREx and James Webb telescopes reveals it's been carrying a chemical cocktail from another star system — one that's unlike anything we've seen in our own comets. Also in today's episode: NASA let an AI drive the Perseverance rover on Mars for two days straight; new research suggests Earth may have hit a rare chemical jackpot during formation that made life possible; the Ring of Fire solar eclipse is just one week away; and Starship is back on track after the Booster 18 disaster, with Flight 12 targeting a March launch window. In This Episode • SpaceX Crew-12: Three launch scrubs, skeleton ISS crew, and the cosmonaut spy subplot • 3I/ATLAS farewell: SPHEREx detects alien chemistry; JWST finds record CO2-to-water ratio • AI drives Perseverance on Mars — 456 metres without human control • Earth's lucky chemistry: why phosphorus and nitrogen almost didn't make it to the surface • Ring of Fire annular solar eclipse — February 17 over Antarctica • Starship Flight 12: Booster 19 passes cryo tests, March launch window in sight Key Links • Full show notes & blog: astronomydaily.io • NASA Crew-12 mission blog: nasa.gov • NASA SPHEREx 3I/ATLAS data: science.nasa.gov • Universe Today — AI drives Perseverance: universetoday.com • Nature Astronomy — Earth habitability study: nature.com Subscribe & Connect Subscribe on Apple Podcasts, Spotify, or wherever you listen.

1
00:00:00.200 --> 00:00:05.639
Four astronauts, one rocket, and weather that just will not cooperate.
2
00:00:06.160 --> 00:00:09.720
The Crew twelve team is in quarantine in Florida, watching
3
00:00:09.759 --> 00:00:11.320
the forecast and waiting.
4
00:00:11.960 --> 00:00:14.800
A visitor from another solar system is heading for the
5
00:00:14.839 --> 00:00:18.440
exit and handing us a chemical blueprint of its home
6
00:00:18.519 --> 00:00:22.199
solar system on the way out. Plus a rover on
7
00:00:22.320 --> 00:00:25.719
Mars just took orders from an AI instead of a
8
00:00:25.800 --> 00:00:27.359
human for the very first time.
9
00:00:28.000 --> 00:00:31.600
All that plus a rare solar eclipse just days away,
10
00:00:32.039 --> 00:00:34.880
new research that could change how we search for life,
11
00:00:35.159 --> 00:00:39.399
and starship making a comeback after a dramatic setback. It's
12
00:00:39.399 --> 00:00:42.240
a big day. Welcome to Astronomy Daily.
13
00:00:42.640 --> 00:00:45.840
Let's get started. Anna take it away.
14
00:00:46.200 --> 00:00:49.960
Hello, and welcome to Astronomy Daily, your daily guide to
15
00:00:50.039 --> 00:00:51.119
what's happening out there.
16
00:00:51.399 --> 00:00:55.679
I'm Anna and I'm Avery. It is Wednesday, February eleventh,
17
00:00:55.840 --> 00:00:59.439
twenty twenty six. We have six stories to get through today,
18
00:00:59.520 --> 00:01:03.079
and it's one of those lineups where every single one
19
00:01:03.079 --> 00:01:04.159
of them earns its place.
20
00:01:04.799 --> 00:01:07.560
We're going to kick off with the ongoing Crew twelve
21
00:01:07.599 --> 00:01:11.120
drama at Cape Canaveral, then swing to deep Space for
22
00:01:11.159 --> 00:01:14.439
the latest from three I Slash Atlas, and then we've
23
00:01:14.480 --> 00:01:17.760
got a mars Ai story that genuinely made me stop
24
00:01:17.799 --> 00:01:21.599
and think, some fascinating new science about why Earth ended
25
00:01:21.680 --> 00:01:25.280
up being habitable at all, a rare solar eclipse just
26
00:01:25.439 --> 00:01:28.239
days away, and a big starship update.
27
00:01:28.879 --> 00:01:31.040
Let's get into it so avery.
28
00:01:31.359 --> 00:01:34.359
As of this morning, the Crew twelve mission has now
29
00:01:34.400 --> 00:01:38.319
been pushed back to no earlier than Friday, February thirteenth.
30
00:01:38.719 --> 00:01:41.439
That is the third attempted launch date in less than
31
00:01:41.480 --> 00:01:41.840
a week.
32
00:01:42.439 --> 00:01:45.599
It really is. Weather has been the culprit each time.
33
00:01:46.040 --> 00:01:49.760
The teams originally had a window on Wednesday, eleventh, today,
34
00:01:50.159 --> 00:01:54.480
but conditions along the Dragon spacecraft flight path just weren't cooperating,
35
00:01:54.560 --> 00:01:58.319
so they waved it off. Then Thursday the twelfth got pushed.
36
00:01:58.920 --> 00:02:02.000
Now they're looking at Friday morning with a planned lift
37
00:02:02.000 --> 00:02:03.760
off at five point fifteen Eastern.
38
00:02:04.439 --> 00:02:07.519
And the reason there's so much urgency here isn't just
39
00:02:07.599 --> 00:02:11.400
that people are impatient. The International Space Station is currently
40
00:02:11.479 --> 00:02:15.000
running on what NASA is calling a skeleton crew. Preue
41
00:02:15.000 --> 00:02:18.360
eleven had to come home early back in January following
42
00:02:18.439 --> 00:02:21.400
a medical issue with one of the astronauts, and since
43
00:02:21.439 --> 00:02:26.080
then the station has been significantly understaffed. Prue twelve is
44
00:02:26.159 --> 00:02:27.719
the relief team.
45
00:02:27.520 --> 00:02:30.680
Which makes every weather delay feel a little more loaded
46
00:02:30.719 --> 00:02:33.439
than usual. The people up there are doing the work
47
00:02:33.439 --> 00:02:36.000
of a full crew with a much smaller team.
48
00:02:36.680 --> 00:02:40.039
So who's making this trip, Well, let's run through them
49
00:02:40.080 --> 00:02:44.439
one more time. Commander is NASA astronaut Jessica Meyer, a
50
00:02:44.520 --> 00:02:48.280
veteran of a previous long duration station mission and well
51
00:02:48.319 --> 00:02:51.800
known for conducting the first all female spacewalk back in
52
00:02:51.879 --> 00:02:56.120
twenty nineteen. Jill be joined by pilot Jack Hathaway, also
53
00:02:56.159 --> 00:02:58.280
from NASA on his first spaceflight.
54
00:02:58.919 --> 00:03:02.479
And then there are two men specialists, Sophie Adnot from
55
00:03:02.520 --> 00:03:07.120
the European Space Agency representing France and Andre Fedjaiyev from
56
00:03:07.199 --> 00:03:10.719
Russia's ros Cosmos. This will be fed Jaiev's second trip
57
00:03:10.759 --> 00:03:13.560
to the station. Once they dock, they're looking at an
58
00:03:13.599 --> 00:03:16.639
eight to nine month stay, longer than usual to cover
59
00:03:16.719 --> 00:03:19.080
the time loss by krue eleven's early departure.
60
00:03:19.680 --> 00:03:22.240
Now, there is a subplot to this mission that I
61
00:03:22.280 --> 00:03:24.520
think a lot of people may not have heard about.
62
00:03:25.000 --> 00:03:29.759
Back in December, Russia's ross Cosmos quietly removed cosmonaut aleg
63
00:03:29.960 --> 00:03:33.479
Artemiev from the Crew twelve mission. The official line was
64
00:03:33.479 --> 00:03:36.719
that he had transitioned to quote other work.
65
00:03:37.080 --> 00:03:39.520
Which is the kind of statement that immediately makes you
66
00:03:39.599 --> 00:03:41.520
want to know what the actual reason is.
67
00:03:42.280 --> 00:03:47.159
Right and investigative outlet The Insider reported that Artemiev was
68
00:03:47.240 --> 00:03:51.240
effectively expelled from the United States by a being accused
69
00:03:51.280 --> 00:03:56.719
of violating international traffic in arms regulations by allegedly photographing
70
00:03:56.879 --> 00:04:01.960
SpaceX engines, documents and other sense technologies with his phone
71
00:04:02.280 --> 00:04:04.039
and then exporting that information.
72
00:04:04.879 --> 00:04:09.360
So he was allegedly taking photos insite SpaceX facilities of
73
00:04:09.439 --> 00:04:13.319
proprietary rocket technology and sending it out of the country.
74
00:04:13.800 --> 00:04:17.000
That appears to be the allegation. He was replaced by
75
00:04:17.040 --> 00:04:21.199
Andre Fadyeev and Ross. Cosmos has said very little publicly,
76
00:04:21.759 --> 00:04:24.920
but it's a striking reminder that even in the cooperative
77
00:04:24.959 --> 00:04:29.120
world of the International Space Station, the geopolitical tensions of
78
00:04:29.120 --> 00:04:32.399
the wider world don't disappear at the door, and it
79
00:04:32.480 --> 00:04:37.040
raises interesting questions about what access international partners are given
80
00:04:37.079 --> 00:04:42.720
to commercial SpaceX facilities. These aren't NASA government sites anyway.
81
00:04:43.000 --> 00:04:45.800
The crew are in quarantine, the rocket is on the pad,
82
00:04:46.240 --> 00:04:48.680
and all eyes are now on the Florida forecast for
83
00:04:48.759 --> 00:04:51.439
Friday will update you the moment there's news.
84
00:04:52.000 --> 00:04:55.319
Our second story takes US to the outer Solar System,
85
00:04:55.399 --> 00:04:59.800
where interstellar comet three I atlass is continuing its fair
86
00:04:59.839 --> 00:05:03.680
way tour. And before it goes, it's been handing scientists
87
00:05:03.759 --> 00:05:06.680
some truly unexpected data just to.
88
00:05:06.639 --> 00:05:09.279
Set the scene. Three I at Lists was discovered in
89
00:05:09.360 --> 00:05:13.439
July twenty twenty five by a telescope in Chile, traveling
90
00:05:13.519 --> 00:05:16.560
far too fast on a trajectory that could impossibly have
91
00:05:16.600 --> 00:05:20.600
originated within our Solar System. It's only the third interstellar
92
00:05:20.639 --> 00:05:24.639
object ever confirmed to have passed through, after Omuamua in
93
00:05:24.680 --> 00:05:27.839
twenty seventeen and Borisov in twenty nineteen.
94
00:05:28.439 --> 00:05:32.839
Dasa's SPEARX telescope observed three I at Lists in December
95
00:05:32.879 --> 00:05:36.839
twenty twenty five, and the results have been remarkable. The
96
00:05:36.920 --> 00:05:41.399
comet's coma has become dramatically more active and chemically complex.
97
00:05:42.040 --> 00:05:48.160
B REX detected water, ice, carbon dioxide, carbon monoxide, organic compounds,
98
00:05:48.399 --> 00:05:52.480
and rocky material being ejected in chunks far larger than
99
00:05:52.480 --> 00:05:56.680
the fine dust grains you'd normally expect. The scientists described
100
00:05:56.680 --> 00:05:59.800
it as a cocktail of chemicals that haven't been exposed
101
00:05:59.800 --> 00:06:01.879
to space for billions of years.
102
00:06:02.360 --> 00:06:05.920
The James Web Space telescope added another layer, finding that
103
00:06:06.000 --> 00:06:09.040
the ratio of carbon dioxide to water in the coma
104
00:06:09.439 --> 00:06:12.240
is approximately eight to one, which is one of the
105
00:06:12.319 --> 00:06:16.319
highest CO two to water ratios ever measured in any comet.
106
00:06:16.879 --> 00:06:20.519
In our solar systems, comets water tends to dominate, so
107
00:06:20.720 --> 00:06:24.040
the implication is three i at lists may have formed
108
00:06:24.160 --> 00:06:27.439
much further from its home star than a typical cometwood
109
00:06:27.920 --> 00:06:31.519
near a CO two ice line. Its chemistry is essentially
110
00:06:31.560 --> 00:06:35.160
telling us something about the architecture of the planetary system
111
00:06:35.279 --> 00:06:35.920
it came from.
112
00:06:36.360 --> 00:06:40.079
There's also data on the comet spin. It rotates once
113
00:06:40.160 --> 00:06:44.279
every sixteen point one six hours, and researchers found it
114
00:06:44.360 --> 00:06:48.920
had strange wobbling jets in a rare sun facing anti tail.
115
00:06:49.480 --> 00:06:52.759
Normally comet tails point away from the Sun, but three
116
00:06:52.800 --> 00:06:56.519
i at lists briefly had one pointing toward it, genuinely
117
00:06:56.600 --> 00:06:57.439
weird behavior.
118
00:06:57.759 --> 00:06:59.959
As of today, three iat list is in the con
119
00:07:00.000 --> 00:07:04.720
installation Gemini, fading beyond naked eye visibility. It's heading towards
120
00:07:04.759 --> 00:07:07.959
a Jupiter flyby in mid March before leaving the Solar
121
00:07:08.000 --> 00:07:11.480
system forever, and there's one more data release to watch for.
122
00:07:11.879 --> 00:07:15.839
Lisa's Juice spacecraft observed three iat lists back in November,
123
00:07:16.199 --> 00:07:19.160
but couldn't transmit the data while using its antenna as
124
00:07:19.160 --> 00:07:22.160
a heat shield. That data is expected to arrive here
125
00:07:22.199 --> 00:07:25.319
on Earth anytime now in February, so there could still
126
00:07:25.360 --> 00:07:26.800
be one more surprise.
127
00:07:26.480 --> 00:07:30.240
Coming when future generations ask what we learned about other
128
00:07:30.360 --> 00:07:33.560
solar systems in twenty twenty five and twenty twenty six,
129
00:07:34.000 --> 00:07:36.439
three I at lists is going to be a big
130
00:07:36.480 --> 00:07:37.279
part of the answer.
131
00:07:37.759 --> 00:07:41.040
Dave travels three IY slash at lists. Don't be a stranger,
132
00:07:41.279 --> 00:07:44.279
although I suppose by definition you always will be.
133
00:07:46.360 --> 00:07:50.560
Now, this next story is one I find genuinely fascinating
134
00:07:50.839 --> 00:07:55.560
because it sits right at the intersection of robotics, artificial intelligence,
135
00:07:55.839 --> 00:08:01.199
and the practical reality of exploring another planet. M NASA
136
00:08:01.240 --> 00:08:04.800
handed the wheel of the Perseverance Mars rover to an AI,
137
00:08:05.439 --> 00:08:11.240
not metaphorically literally, the AI generated the rovers driving waypoints,
138
00:08:11.439 --> 00:08:15.279
and the rover followed them without human control across two
139
00:08:15.399 --> 00:08:18.839
separate days, covering a total of four hundred and fifty
140
00:08:18.959 --> 00:08:19.680
six meters.
141
00:08:20.160 --> 00:08:22.720
And just to be clear, this isn't NASA hopping on
142
00:08:22.759 --> 00:08:26.399
a bandwagon. They have been working on autonomous rover navigation
143
00:08:26.639 --> 00:08:30.360
for years out of sheer necessity. Mars is so far
144
00:08:30.439 --> 00:08:33.559
away that a round trip radio signal takes around twenty
145
00:08:33.600 --> 00:08:37.399
five minutes. That means every driving instruction you send has
146
00:08:37.440 --> 00:08:41.759
a built in delay, and every unexpected obstacle requires another
147
00:08:41.919 --> 00:08:46.360
twenty five minutes to respond to. Autonomous navigation isn't a luxury,
148
00:08:46.519 --> 00:08:48.000
it's a practical requirement.
149
00:08:48.279 --> 00:08:52.720
So in this demonstration, the AI analyzed orbital images from
150
00:08:52.799 --> 00:08:56.840
the Mars Reconnaissance orbiter's high rise camera as well as
151
00:08:56.919 --> 00:09:02.559
digital elevation models. It identified how sand traps, boulder fields,
152
00:09:02.759 --> 00:09:07.720
bedrock rocky outcrops, and then generated a path defined by
153
00:09:07.720 --> 00:09:12.120
a series of waypoints to avoid them. From there, Perseverance's
154
00:09:12.240 --> 00:09:17.200
own onboard auto navigation system took over to actually execute
155
00:09:17.200 --> 00:09:17.879
the drive.
156
00:09:18.000 --> 00:09:22.080
And importantly, before those AI generated waypoints were sent to Mars,
157
00:09:22.279 --> 00:09:26.159
they were tested here on Earth using Perseverance's engineering twin,
158
00:09:26.639 --> 00:09:30.600
a full scale physical replica at JPL's Mars yard, So
159
00:09:30.799 --> 00:09:33.679
this wasn't a blind experiment. There was a safety net
160
00:09:33.720 --> 00:09:34.159
built in.
161
00:09:34.840 --> 00:09:38.679
The AI in question is built on Anthropics Claude, which
162
00:09:38.840 --> 00:09:42.000
regular listeners may know as the same AI that helps
163
00:09:42.039 --> 00:09:45.720
power this show. So there's a certain pleasing symmetry and
164
00:09:45.799 --> 00:09:48.000
reporting on that it really is.
165
00:09:48.200 --> 00:09:51.320
And the engineers are excited about what comes next. One
166
00:09:51.320 --> 00:09:53.840
of the current limitations is that the longer a rover
167
00:09:54.039 --> 00:09:58.879
drives without human relocalization, essentially humans checking in to confirm
168
00:09:58.919 --> 00:10:02.120
where it is on the map, the more positional uncertainty
169
00:10:02.159 --> 00:10:05.639
build up. Over six hundred and fifty five meters, that
170
00:10:05.759 --> 00:10:09.399
uncertainty can grow to around thirty three meters. The goal
171
00:10:09.559 --> 00:10:12.720
is to use AI to solve that relocalization problem too,
172
00:10:13.159 --> 00:10:17.360
so rovers can handle kilometer scaled drives entirely on their own.
173
00:10:17.679 --> 00:10:21.080
And beyond Mars. This matters for the whole future of
174
00:10:21.159 --> 00:10:26.039
deep space exploration. NASA's Dragonfly mission to Saturn's moon Titan
175
00:10:26.320 --> 00:10:30.080
will rely heavily on AI for autonomous navigation as it
176
00:10:30.159 --> 00:10:34.279
flies around in Titan's thick atmosphere. The further from Earth
177
00:10:34.320 --> 00:10:38.759
you go, the more critical autonomous systems become, because waiting
178
00:10:38.799 --> 00:10:41.559
twenty five minutes for a signal is one thing, but
179
00:10:41.679 --> 00:10:44.279
waiting hours or days is quite another.
180
00:10:45.000 --> 00:10:48.440
The vision the JPL team laid out is compelling intelligence
181
00:10:48.480 --> 00:10:51.279
systems not just at mission control here on Earth, but
182
00:10:51.399 --> 00:10:55.679
embedded in the rovers, helicopters, and drones themselves, trained on
183
00:10:55.759 --> 00:10:59.600
the collective knowledge of NASA's engineers and scientists. The Mars
184
00:10:59.679 --> 00:11:03.399
rover of twenty thirty five may look quite different from perseverance.
185
00:11:04.000 --> 00:11:06.679
Our next story is one of those pieces of research
186
00:11:06.759 --> 00:11:10.399
that sounds almost philosophical at first, but turns out to
187
00:11:10.480 --> 00:11:14.879
have very concrete scientific implications. A new study published in
188
00:11:15.000 --> 00:11:18.279
Nature Astronomy has found that life on Earth may be
189
00:11:18.480 --> 00:11:23.000
thanks to an extraordinarily lucky chemical accident during our planet's
190
00:11:23.000 --> 00:11:26.279
formation nearly four point six billion years ago.
191
00:11:27.080 --> 00:11:30.559
And when they say lucky, they mean it. The research
192
00:11:30.639 --> 00:11:34.960
suggests that two elements absolutely essential for life as we
193
00:11:35.039 --> 00:11:39.679
know it, phosphorus and nitrogen, only stayed accessible on Earth's
194
00:11:39.679 --> 00:11:43.799
surface because of a very precise and apparently quite rare
195
00:11:44.279 --> 00:11:47.320
balance of oxygen during the planet's earliest formation.
196
00:11:47.840 --> 00:11:51.120
Here's how it works. When a young rocky planet forms,
197
00:11:51.240 --> 00:11:55.399
it's initially molten, a churning ball of liquid rock. As
198
00:11:55.440 --> 00:11:59.320
heavy metals sink inward to form the core. Lighter materials
199
00:11:59.399 --> 00:12:03.919
stay near the surface during this chaotic stage called core formation.
200
00:12:04.360 --> 00:12:08.279
The amount of oxygen present determines where other elements end up.
201
00:12:08.679 --> 00:12:12.879
The researchers from Etch Zurich found that oxygen levels need
202
00:12:12.960 --> 00:12:16.799
to fall within a surprisingly narrow range for both phosphorus
203
00:12:16.840 --> 00:12:20.639
and nitrogen to remain in the mantle and crust available
204
00:12:20.720 --> 00:12:21.720
for future life.
205
00:12:22.240 --> 00:12:25.679
To little oxygen and phosphorus bonds with iron and gets
206
00:12:25.759 --> 00:12:28.519
dragged into the core, taking away a key ingredient for
207
00:12:28.639 --> 00:12:33.080
DNA sell membranes and energy transfer. Too much oxygen and
208
00:12:33.200 --> 00:12:36.600
nitrogen is more easily lost to space. Either way, the
209
00:12:36.679 --> 00:12:40.639
chemistry needed for life never fully comes together. Earth hit
210
00:12:40.679 --> 00:12:43.600
this sweet spot, what the researchers are calling a chemical
211
00:12:43.639 --> 00:12:45.519
Goldilock zone precisely.
212
00:12:46.200 --> 00:12:49.759
The lead researcher, Craig Walton put it clearly, if Earth
213
00:12:49.759 --> 00:12:52.159
had had just a little more or a little less
214
00:12:52.200 --> 00:12:55.440
oxygen during core formation, there would not have been enough
215
00:12:55.440 --> 00:12:59.240
phosphorus or nitrogen for the development of life. They also
216
00:12:59.360 --> 00:13:03.200
modeled mar and found it likely had the wrong oxygen balance,
217
00:13:03.559 --> 00:13:06.879
more phosphorus in the mantle than Earth but less nitrogen,
218
00:13:07.279 --> 00:13:09.639
challenging conditions for life as we know it.
219
00:13:10.200 --> 00:13:13.480
This is a significant challenge to how we've traditionally thought
220
00:13:13.519 --> 00:13:17.159
about the search for life. The habitable zone, the region
221
00:13:17.200 --> 00:13:20.360
around a star where liquid water can exist on the surface,
222
00:13:20.720 --> 00:13:24.399
has been our go to framework, but this research suggests
223
00:13:24.480 --> 00:13:27.600
that even a planet in the perfect orbital position with
224
00:13:27.759 --> 00:13:32.600
liquid water could be fundamentally incapable of supporting life if
225
00:13:32.600 --> 00:13:35.200
its internal chemistry didn't form correctly.
226
00:13:35.720 --> 00:13:39.960
And here's the hopeful flip side. The oxygen conditions during
227
00:13:40.000 --> 00:13:43.440
planetary formation are linked to the chemistry of the host
228
00:13:43.480 --> 00:13:47.440
star itself, because planets form from the same material as
229
00:13:47.440 --> 00:13:51.519
their stars, So in principle, by looking at stellar chemistry
230
00:13:51.799 --> 00:13:55.240
we might be able to predict which planetary systems had
231
00:13:55.279 --> 00:13:58.399
the right conditions from the start. Walton's advice for the
232
00:13:58.399 --> 00:14:02.279
search look for solars systems with stars that resemble our
233
00:14:02.360 --> 00:14:03.039
own sun.
234
00:14:03.519 --> 00:14:06.399
It makes the Earth feel even more special and the
235
00:14:06.519 --> 00:14:10.720
universe feel a little more vast and empty. All right,
236
00:14:11.000 --> 00:14:15.879
from the philosophical to the spectacular. In exactly one week's time,
237
00:14:16.039 --> 00:14:19.759
on February seventeenth, an annular solar eclipse is going to
238
00:14:19.799 --> 00:14:23.279
sweep across the Southern Hemisphere. This is the so called
239
00:14:23.440 --> 00:14:26.679
ring of fire eclipse, where the Moon passes directly in
240
00:14:26.679 --> 00:14:29.320
front of the Sun, but because it's at a slightly
241
00:14:29.440 --> 00:14:32.799
greater distance from Earth than usual, it appears a little
242
00:14:32.879 --> 00:14:36.120
smaller than the Sun's disk. The result is a thin,
1
00:00:00.200 --> 00:00:05.639
2
00:00:06.160 --> 00:00:09.720
