1
00:00:00.200 --> 00:00:02.960
Welcome to Astronomy Daily, your daily dose of space and

2
00:00:03.000 --> 00:00:06.639
astronomy news. I'm Anna, and we've got a packed show

3
00:00:06.639 --> 00:00:09.279
for you today, filled with some incredible developments in the

4
00:00:09.320 --> 00:00:12.720
world of space exploration and astronomy. We'll be diving into

5
00:00:12.720 --> 00:00:17.039
SpaceX's latest preparations for their next Starship test flight, which

6
00:00:17.079 --> 00:00:19.679
promises to push the boundaries of what's possible with the

7
00:00:19.679 --> 00:00:23.480
world's largest rocket. We'll also check in on NASA's Jet

8
00:00:23.480 --> 00:00:28.039
Propulsion Laboratory as it faces challenges from the Los Angeles wildfires.

9
00:00:28.359 --> 00:00:30.679
And I'll tell you about a special opportunity to see

10
00:00:30.719 --> 00:00:35.200
Mars at its brightest this weekend. Plus, we've got fascinating

11
00:00:35.240 --> 00:00:38.520
stories about the world's first wooden satellite just deployed from

12
00:00:38.520 --> 00:00:42.039
the International Space Station and a rare double flash event

13
00:00:42.119 --> 00:00:45.880
observed from a super massive black hole that's got astronomers excited.

14
00:00:46.359 --> 00:00:51.039
Let's get started. SpaceX has just reached another milestone in

15
00:00:51.079 --> 00:00:55.159
their ambitious Starship program, successfully stacking their next vehicle for

16
00:00:55.240 --> 00:00:59.159
Flight seven at their Starbase facility in South Texas. The

17
00:00:59.200 --> 00:01:03.159
fully assembled Pocket now stands an impressive four hundred feet tall,

18
00:01:03.600 --> 00:01:06.879
maintaining its status as the largest and most powerful launch

19
00:01:07.000 --> 00:01:11.200
vehicle ever built. This upcoming mission, scheduled for Monday at

20
00:01:11.239 --> 00:01:15.000
five pm Eastern Time, isn't just another test flight. It

21
00:01:15.079 --> 00:01:19.200
represents a significant leap forward in Starship's development. The new

22
00:01:19.280 --> 00:01:23.799
vehicle features several crucial upgrades, including improvements to its flight computer,

23
00:01:24.200 --> 00:01:29.079
avionic systems, and heat shield design. One particularly interesting modification

24
00:01:29.280 --> 00:01:32.400
is the repositioning of the forward flaps, which have been

25
00:01:32.439 --> 00:01:34.760
moved away from the heat shield to better handle the

26
00:01:34.799 --> 00:01:40.319
intense temperatures during re entry. For the first time, SpaceX

27
00:01:40.359 --> 00:01:43.640
will attempt to deploy simulated Starlink satellites during the sixty

28
00:01:43.719 --> 00:01:48.840
six minute flight, marking an important step towards Starship's operational capabilities.

29
00:01:49.239 --> 00:01:51.920
They're also breaking new ground by reusing an engine on

30
00:01:51.959 --> 00:01:55.319
the Super Heavy Booster, the massive first stage powered by

31
00:01:55.359 --> 00:01:59.280
thirty three Raptor engines. Perhaps most exciting is the planned

32
00:01:59.319 --> 00:02:02.959
recovery attempt of the Super Heavy Booster. If conditions are right,

33
00:02:03.239 --> 00:02:05.799
SpaceX will try to catch the massive rocket using the

34
00:02:05.879 --> 00:02:11.719
launch tower's mechanical arms nicknamed the chopsticks. While they've demonstrated

35
00:02:11.719 --> 00:02:15.280
this capability before, during flight five, they're taking no chances.

36
00:02:15.759 --> 00:02:20.120
The catch will only proceed if all safety criteria are met. Otherwise,

37
00:02:20.400 --> 00:02:22.599
the booster will make a controlled splash down in the

38
00:02:22.599 --> 00:02:26.400
Gulf of Mexico. This mission could be the first of

39
00:02:26.479 --> 00:02:29.159
up to twenty five Starship launches planned for this year,

40
00:02:29.520 --> 00:02:34.560
showcasing SpaceX's accelerating pace of development. These tests are crucial

41
00:02:34.639 --> 00:02:38.280
not just for SpaceX's Mars ambitions, but also for NASA's

42
00:02:38.400 --> 00:02:42.199
Artemis program, as Starship has been selected to land astronauts

43
00:02:42.199 --> 00:02:46.680
on the lunar surface in twenty twenty seven. Next up,

44
00:02:46.840 --> 00:02:49.840
an update for you concerning the wildfires around Los Angeles.

45
00:02:50.759 --> 00:02:55.319
In some concerning news from California, NASA's Jet Propulsion Laboratory

46
00:02:55.680 --> 00:02:59.080
has found itself uncomfortably close to the raging eaten fire

47
00:02:59.159 --> 00:03:03.080
that's been devastatdating neighborhoods north of Los Angeles. Thanks to

48
00:03:03.120 --> 00:03:07.080
the incredible efforts of firefighters, JPL itself remains untouched by

49
00:03:07.080 --> 00:03:10.199
the flames, but the impact on the JPL community has

50
00:03:10.240 --> 00:03:14.439
been severe. More than one hundred and fifty JPL employees

51
00:03:14.759 --> 00:03:18.199
have lost their homes completely in this disaster, with many

52
00:03:18.240 --> 00:03:21.879
more being forced to evacuate. The facility, which serves as

53
00:03:22.000 --> 00:03:26.599
NASA's primary center for planetary exploration and manages crucial missions

54
00:03:26.639 --> 00:03:30.080
like the perseverance and curiosity. Mars Rovers has had to

55
00:03:30.080 --> 00:03:33.960
temporarily close its doors. All but essential personnel have been

56
00:03:34.039 --> 00:03:37.719
ordered to work remotely through at least January seventeenth. The

57
00:03:37.759 --> 00:03:41.159
Eton Fire has already consumed around fourteen thousand acres of

58
00:03:41.240 --> 00:03:45.120
land and is currently only three percent contained. It's just

59
00:03:45.199 --> 00:03:48.919
one of several fires causing havoc in the Los Angeles area,

60
00:03:49.360 --> 00:03:51.680
with the Palisades Fire on the western side of the

61
00:03:51.680 --> 00:03:55.039
city having burned through more than twenty thousand acres and

62
00:03:55.080 --> 00:04:00.039
showing similar resistance to containment efforts. This situation highlights a

63
00:04:00.080 --> 00:04:03.439
growing challenge for major scientific facilities in areas prone to

64
00:04:03.520 --> 00:04:07.479
natural disasters. JPL's location at the foot of the San

65
00:04:07.560 --> 00:04:11.439
Gabriel Mountains, while ideal for many aspects of its operations,

66
00:04:11.840 --> 00:04:15.840
places it in a vulnerable position during California's increasingly severe

67
00:04:15.840 --> 00:04:21.439
fire seasons. Despite these challenges, the laboratory's essential operations continue

68
00:04:21.639 --> 00:04:25.920
demonstrating the resilience of our space exploration infrastructure even in

69
00:04:25.920 --> 00:04:30.480
the face of natural disasters. The dedication of first responders

70
00:04:30.519 --> 00:04:34.000
has been crucial in protecting this vital facility, which plays

71
00:04:34.040 --> 00:04:37.360
such an important role in our ongoing exploration of the

72
00:04:37.399 --> 00:04:42.040
solar system. While the laboratory itself remains safe, the human

73
00:04:42.079 --> 00:04:45.319
impact on the JPL community serves as a sobering reminder

74
00:04:45.399 --> 00:04:49.240
of the increasing challenges posed by natural disasters to our

75
00:04:49.319 --> 00:04:54.639
scientific institutions. Stargazers, you're in for a treat this weekend,

76
00:04:54.680 --> 00:04:57.680
as Mars is about to put on its most spectacular

77
00:04:57.759 --> 00:05:01.680
show of the year. This Sunday, January twelfth, the red

78
00:05:01.680 --> 00:05:04.639
planet will make its closest approach to Earth, and event

79
00:05:04.720 --> 00:05:08.720
astronomers call perigy. During this cosmic close up, Mars will

80
00:05:08.759 --> 00:05:11.439
appear larger and brighter in our night sky than at

81
00:05:11.480 --> 00:05:14.319
any other time in twenty twenty four. If you're planning

82
00:05:14.360 --> 00:05:17.439
to catch this celestial spectacle, the best viewing time will

83
00:05:17.480 --> 00:05:20.600
be around midnight, when Mars reaches its highest point in

84
00:05:20.639 --> 00:05:23.839
the southern sky. The planet will be visible for most

85
00:05:23.879 --> 00:05:27.000
of the night, first appearing in the northeastern sky during

86
00:05:27.040 --> 00:05:30.920
early evening and remaining observable until dawn begins to break

87
00:05:30.920 --> 00:05:34.839
the next morning. During this close approach, Mars will come

88
00:05:34.879 --> 00:05:38.079
within just zero point sixty four astronomical units of Earth

89
00:05:38.519 --> 00:05:41.560
that's about fifty nine point five million miles. While this

90
00:05:41.639 --> 00:05:44.560
might sound like quite a distance, it's actually quite close

91
00:05:44.600 --> 00:05:49.040
in astronomical terms. For perspective, Mars usually orbits at an

92
00:05:49.079 --> 00:05:52.000
average distance of one point five astronomical units from the

93
00:05:52.040 --> 00:05:54.560
Sun and can be as far as two point six

94
00:05:54.639 --> 00:05:58.720
units from Earth at its most distant point. This weekend's

95
00:05:58.759 --> 00:06:02.519
close encounter is particularly special as it coincides with Mars's

96
00:06:02.519 --> 00:06:06.720
opposition on January sixteenth, when Earth will be directly between

97
00:06:06.759 --> 00:06:10.639
Mars and the Sun. This alignment means the Sun's full

98
00:06:10.639 --> 00:06:13.680
glare will illuminate the Martian surface as seen from Earth,

99
00:06:14.120 --> 00:06:18.120
making it an ideal time for observation. While Mars will

100
00:06:18.160 --> 00:06:21.600
be noticeably brighter than usual with a magnitude of dash

101
00:06:21.639 --> 00:06:24.600
one dot four comma, don't expect to see any surface

102
00:06:24.639 --> 00:06:27.759
details with your naked eye. It will still appear as

103
00:06:27.759 --> 00:06:30.839
a bright, reddish point of light in the sky. However,

104
00:06:31.040 --> 00:06:34.040
if you have access to binoculars or a telescope, this

105
00:06:34.199 --> 00:06:36.800
is an excellent opportunity to try spotting some of the

106
00:06:36.839 --> 00:06:40.720
red planet's famous surface features. This is the closest Mars

107
00:06:40.759 --> 00:06:43.560
has been to Earth since twenty twenty two, so make

108
00:06:43.600 --> 00:06:47.120
sure to take advantage of this rare viewing opportunity the

109
00:06:47.160 --> 00:06:49.560
next time Mars will appear this large and brighten our

110
00:06:49.560 --> 00:06:52.480
skies won't be for quite some time, making this weekend

111
00:06:52.560 --> 00:06:57.519
a must watch event for astronomy enthusiasts. In a groundbreaking

112
00:06:57.560 --> 00:07:01.879
development for sustainable space technology, the world's first wooden satellite

113
00:07:01.959 --> 00:07:05.879
has been successfully deployed from the International Space Station. This

114
00:07:06.000 --> 00:07:11.839
innovative spacecraft, named Lignosat, represents a fascinating experiment in using

115
00:07:11.879 --> 00:07:17.079
renewable materials for space exploration. Developed through a collaboration between

116
00:07:17.160 --> 00:07:21.800
Kyoto University and Japanese wood processing company Sumitomo Forestry, this

117
00:07:21.920 --> 00:07:25.439
tiny cube satellite measures just four inches on each side

118
00:07:25.680 --> 00:07:29.519
and is constructed primarily from magnolia wood. Over the next

119
00:07:29.560 --> 00:07:32.319
six months, it will put this natural material to the

120
00:07:32.439 --> 00:07:36.600
ultimate test in the harsh conditions of Earth orbit. The

121
00:07:36.720 --> 00:07:41.240
extreme environment of space presents some remarkable challenges for any material.

122
00:07:42.000 --> 00:07:45.439
During each ninety minute orbit, the satellite will experience dramatic

123
00:07:45.480 --> 00:07:48.600
temperature swings from a scorching two hundred and fifty degrees

124
00:07:48.680 --> 00:07:51.959
fahrenheit when facing the Sun to a frigid minus two

125
00:07:52.040 --> 00:07:55.199
hundred and fifty degrees in Earth's shadow. Add to that

126
00:07:55.360 --> 00:07:59.000
the constant bombardment of charged particles from solar wind, and

127
00:07:59.040 --> 00:08:01.639
you've got quite the endureance test for our wooden pioneer.

128
00:08:02.519 --> 00:08:05.800
But why would well, it turns out this isn't just

129
00:08:05.839 --> 00:08:09.000
about proving we can build satellites from trees. There's a

130
00:08:09.040 --> 00:08:14.079
serious environmental concern driving this innovation. Traditional satellites built primarily

131
00:08:14.160 --> 00:08:18.720
from aluminum alloys create potentially harmful metallic dust when they

132
00:08:18.759 --> 00:08:21.600
burn up during re entry. This debris can linger in

133
00:08:21.600 --> 00:08:25.439
our upper atmosphere, potentially affecting our climate. Wood being a

134
00:08:25.519 --> 00:08:29.439
natural material, could offer a more environmentally friendly alternative that

135
00:08:29.519 --> 00:08:33.519
simply burns away cleanly. The mission will carefully monitor how

136
00:08:33.559 --> 00:08:37.720
the wooden structure holds up against these space hazards, including

137
00:08:37.759 --> 00:08:40.960
whether Earth's magnetic field can penetrate the wooden body and

138
00:08:41.039 --> 00:08:45.759
interfere with its operations. If successful, this experiment could pave

139
00:08:45.799 --> 00:08:49.399
the way for a new generation of environmentally conscious satellites,

140
00:08:49.759 --> 00:08:53.960
potentially transforming how we approach spacecraft construction in an era

141
00:08:54.120 --> 00:08:58.440
of increasing orbital traffic. The timing couldn't be more crucial,

142
00:08:58.759 --> 00:09:01.720
as research suggests that the growing number of satellites in

143
00:09:01.840 --> 00:09:05.519
orbit could lead to concerning levels of aluminum oxide and

144
00:09:05.600 --> 00:09:09.480
other potentially harmful compounds in our upper atmosphere. This wooden

145
00:09:09.480 --> 00:09:12.279
satellite might just represent our first step toward a more

146
00:09:12.360 --> 00:09:16.440
sustainable future in space. Seems like a day doesn't go

147
00:09:16.480 --> 00:09:19.399
by without a black hole story, and today is no exception.

148
00:09:20.360 --> 00:09:25.240
Astronomers have recently witnessed a fascinating cosmic spectacle, a supermassive

149
00:09:25.279 --> 00:09:27.679
black hole that appears to be having seconds of its

150
00:09:27.679 --> 00:09:31.639
stellar meal. This rare event, known as ss N twenty

151
00:09:31.639 --> 00:09:34.840
two CI, has displayed two distinct flares of light as

152
00:09:34.840 --> 00:09:38.360
it consumes its unfortunate victim, located about four hundred eight

153
00:09:38.399 --> 00:09:41.840
million light years away from Earth. What makes this double

154
00:09:41.840 --> 00:09:45.879
flash event particularly intriguing is how normal it appears compared

155
00:09:45.919 --> 00:09:49.799
to other similar phenomena. The black hole at the center

156
00:09:49.879 --> 00:09:53.440
of this cosmic feast weighs in at around three million

157
00:09:53.519 --> 00:09:56.720
times the mass of our Sun, making it comparable to

158
00:09:56.799 --> 00:10:01.080
our own galaxies central black hole, Sagittarius Ace star, the

159
00:10:01.200 --> 00:10:04.600
unfortunate star being consumed, appears to be similar in size

160
00:10:04.679 --> 00:10:08.279
to our Sun. The current theory suggests this unusual double

161
00:10:08.320 --> 00:10:10.559
flare might be the result of what astronomers call a

162
00:10:10.639 --> 00:10:15.200
Hill's capture picture. This a pair of binary stars wandering

163
00:10:15.200 --> 00:10:18.519
too close to the black hole as they approach the

164
00:10:18.559 --> 00:10:22.879
immense gravitational forces separate the pair, flinging one star away

165
00:10:22.879 --> 00:10:25.480
to freedom, while the other becomes trapped in an elliptical

166
00:10:25.559 --> 00:10:28.720
orbit around the black hole like a cosmic dance partner

167
00:10:28.759 --> 00:10:32.519
it can escape. Each time this trap star swings close

168
00:10:32.559 --> 00:10:35.559
to the black hole, it undergoes partial destruction in a

169
00:10:35.600 --> 00:10:40.519
process colorfully known as spaghettification. The star gets stretched and squeezed,

170
00:10:40.960 --> 00:10:43.759
losing some of its material to the black hole's accretion disk,

171
00:10:44.360 --> 00:10:48.080
creating these brilliant flares we observe. The consistency between the

172
00:10:48.120 --> 00:10:51.960
two flares, separated by seven hundred and twenty days, suggests

173
00:10:52.000 --> 00:10:55.639
we're watching the same star being repeatedly torn apart. The

174
00:10:55.679 --> 00:10:58.759
best part, astronomers believe they know when the next act

175
00:10:58.799 --> 00:11:02.440
of this cosmic drama might have. If their calculations are correct,

176
00:11:02.919 --> 00:11:05.559
we should see a third flare in early twenty twenty six.

177
00:11:06.399 --> 00:11:10.480
This predictability is incredibly rare and valuable, giving scientists an

178
00:11:10.600 --> 00:11:14.799
unprecedented opportunity to prepare their observations in advance, rather than

179
00:11:14.840 --> 00:11:19.480
catching these events by chance. This celestial performance isn't just spectacular.

180
00:11:19.879 --> 00:11:23.519
It's helping us understand how super massive black holes interact

181
00:11:23.559 --> 00:11:27.840
with stars, and providing new insights into these mysterious cosmic giants,

182
00:11:28.159 --> 00:11:31.480
and who knows when twenty twenty six rolls around, this

183
00:11:31.600 --> 00:11:34.799
persistent Stellar survivor might have even more surprises in store

184
00:11:34.840 --> 00:11:39.639
for us. Well, that's all for today's episode of Astronomy Daily.
