00:00:00.240 --> 00:00:03.240
Welcome to Astronomy Daily, a podcast where we dive into

2
00:00:03.279 --> 00:00:06.440
the latest space and astronomy news. I'm your host, Anna,

3
00:00:06.559 --> 00:00:09.720
ready to take you on a cosmic journey. In today's episode,

4
00:00:09.800 --> 00:00:13.960
we'll cover intriguing updates from NASA, the latest asteroid encounters,

5
00:00:14.320 --> 00:00:18.760
skywatching highlights for September, and fascinating experiments on the International

6
00:00:18.760 --> 00:00:21.920
Space Station. Get comfortable and prepare to explore the wonders

7
00:00:21.920 --> 00:00:24.559
of our universe. Let's kick things off with a story

8
00:00:24.559 --> 00:00:27.600
from the There's No Smoke Without firefile. There was quite

9
00:00:27.600 --> 00:00:30.480
a bit of drama recently between NASA and Boeing as

10
00:00:30.519 --> 00:00:33.240
tension brewed during meetings over how to bring back two

11
00:00:33.280 --> 00:00:38.079
astronauts currently stranded on the International Space Station. Originally, astronauts

12
00:00:38.079 --> 00:00:40.600
Butch Wilmore and Sunny Williams were scheduled for a brief

13
00:00:40.600 --> 00:00:44.119
week long mission in June. However, due to several technical

14
00:00:44.159 --> 00:00:48.479
malfunctions with Boeing Starliner capsule, that timeline has been extended

15
00:00:48.880 --> 00:00:52.159
and they're not expected to return until February twenty twenty five,

16
00:00:52.600 --> 00:00:55.679
when the space X Crew nine mission comes to the rescue.

17
00:00:55.880 --> 00:00:59.560
The Starliner capsule had several critical issues, including thruster malfunctions,

18
00:00:59.560 --> 00:01:03.320
and helium leaks, which understandably raise safety concerns for NASA.

19
00:01:03.880 --> 00:01:07.120
Despite Boeing's public confidence in their spaceship, the lack of

20
00:01:07.159 --> 00:01:10.879
their executives at recent NASA press briefings spurred rumors of

21
00:01:10.920 --> 00:01:13.680
a serious rift between the two giants of space travel.

22
00:01:14.200 --> 00:01:18.040
NASA's Steve Stitch, the program manager for the Commercial Crew program,

23
00:01:18.439 --> 00:01:21.519
admitted there was tension in the meetings, but he downplayed

24
00:01:21.560 --> 00:01:25.560
reports of shouting matches. Instead, he characterized the interactions as

25
00:01:25.560 --> 00:01:29.640
intense technical discussions where both sides were heavily invested in

26
00:01:29.680 --> 00:01:32.920
parsing out the details. One of the biggest sticking points

27
00:01:33.040 --> 00:01:35.840
was Boeing's belief in their predictive model for the thruster

28
00:01:35.959 --> 00:01:39.920
degradation of Starliner, a model that NASA's team found too

29
00:01:40.000 --> 00:01:43.159
uncertain to rely on. NASA was not willing to gamble

30
00:01:43.159 --> 00:01:46.599
with the lives of their astronauts given these uncertainties, so

31
00:01:46.840 --> 00:01:50.079
despite Boeing's attempts to persuade NASA of the capsule's reliability,

32
00:01:50.519 --> 00:01:52.920
the decision was made to enlist SpaceX to ferry the

33
00:01:52.920 --> 00:01:57.200
astronauts back safely. Nonetheless, Wilmore and Williams remain in good

34
00:01:57.239 --> 00:02:00.840
spirits and are maintaining regular contact with their family. They

35
00:02:00.879 --> 00:02:04.280
were even sent better fitting suits during a recent resupply mission,

36
00:02:04.680 --> 00:02:07.680
so they are no longer dependent on borrowed clothes. It's

37
00:02:07.719 --> 00:02:10.719
a good reminder of the cooperative spirit and resilience of

38
00:02:10.759 --> 00:02:14.639
the astronaut community despite the challenges they face. As for

39
00:02:14.680 --> 00:02:17.680
the Starliner capsule, it's scheduled to undock from the ISS

40
00:02:17.719 --> 00:02:20.400
soon and will execute a breakout burn to ensure a

41
00:02:20.439 --> 00:02:23.479
safe departure and return to Earth. This marks a crucial

42
00:02:23.479 --> 00:02:26.439
turning point for NASA and Boeing, one that likely sets

43
00:02:26.520 --> 00:02:29.560
the stage for how future collaborations and contracts will be handled.

44
00:02:30.000 --> 00:02:33.319
These developments remind us how intense and complex space missions

45
00:02:33.360 --> 00:02:37.319
can be, underscoring the high stakes and technical challenges inherent

46
00:02:37.400 --> 00:02:41.319
in human spaceflight. Next up some positive news, NASA's Europa

47
00:02:41.319 --> 00:02:44.319
Clipper mission is officially cleared for launch in October twenty

48
00:02:44.360 --> 00:02:47.520
twenty four, and excitement is building for what promises to

49
00:02:47.520 --> 00:02:52.360
be a groundbreaking exploration of one of Jupiter's most intriguing moons, Europa.

50
00:02:52.919 --> 00:02:56.919
This icy celestial body has long fascinated scientists due to

51
00:02:56.960 --> 00:03:00.759
its potential for harboring a subsurface ocean which contained twice

52
00:03:00.759 --> 00:03:04.080
as much water as all of Earth's seas combined, imagine

53
00:03:04.080 --> 00:03:08.960
the possibilities. Equipped with nine advanced instruments, including cameras, ground

54
00:03:09.039 --> 00:03:13.360
penetrating radar, and spectrometers, the Europa Clipper spacecraft is designed

55
00:03:13.400 --> 00:03:16.719
to delve deep into Europa's mysteries. It will carry out

56
00:03:16.840 --> 00:03:20.639
multiple close flybys of the Moon, allowing it to thoroughly

57
00:03:20.719 --> 00:03:24.240
examine the environment beneath the icy crust, as well as

58
00:03:24.280 --> 00:03:28.080
the Moon's composition and geology. One of the mission's primary

59
00:03:28.120 --> 00:03:31.240
goals is to assess whether there are regions beneath Europa's

60
00:03:31.240 --> 00:03:35.039
surface that could support life. The detailed exploration aims to

61
00:03:35.039 --> 00:03:38.960
deepen our understanding of Europa's potential for habitability and could

62
00:03:38.960 --> 00:03:42.080
have significant implications for the search for life beyond Earth.

63
00:03:42.599 --> 00:03:45.919
Launching atop a SpaceX Falcon heavy rocket from NASA's Kennedy

64
00:03:45.960 --> 00:03:48.800
Space Center in Florida, the Clipper will embark on a

65
00:03:48.879 --> 00:03:51.360
journey set to culminate in its arrival at Jupiter in

66
00:03:51.400 --> 00:03:54.520
twenty thirty Over the course of three years, between twenty

67
00:03:54.560 --> 00:03:57.719
thirty one and twenty thirty four, the spacecraft will perform

68
00:03:57.879 --> 00:04:02.199
nearly fifty flybys of Europa. This extended close encounter strategy

69
00:04:02.560 --> 00:04:05.919
will provide scientists with an unprecedented amount of data about

70
00:04:05.919 --> 00:04:10.000
this enigmatic moon. Initially, there were concerns about the spacecraft's

71
00:04:10.000 --> 00:04:14.800
ability to withstand the intense radiation environment surrounding Jupiter. Earlier

72
00:04:14.840 --> 00:04:18.279
tests revealed that its transistors, which control the flow of electricity,

73
00:04:18.360 --> 00:04:23.160
were failing at unexpectedly low radiation doses. However, recent tests

74
00:04:23.160 --> 00:04:26.879
have confirmed that the transistors can endure the radiation expected

75
00:04:26.959 --> 00:04:31.600
during the mission, alleviating previous concerns and ensuring the spacecraft's

76
00:04:31.639 --> 00:04:35.160
operational integrity. Before the mission can proceed to its final

77
00:04:35.199 --> 00:04:37.879
launch preparations, it must pass a critical review known as

78
00:04:37.959 --> 00:04:42.199
Key Decision Point E, slated for September ninth. This milestone

79
00:04:42.199 --> 00:04:45.079
will determine if the Europa Clipper is ready to move forward,

80
00:04:45.439 --> 00:04:47.360
paving the way for what could be one of the

81
00:04:47.360 --> 00:04:50.480
most thrilling chapters in our quest to uncover the secrets

82
00:04:50.480 --> 00:04:53.079
of our Solar system. Stay tuned as we keep you

83
00:04:53.160 --> 00:04:56.319
updated on this incredible mission and its potential to rewrite

84
00:04:56.360 --> 00:04:59.360
our understanding of where life might exist beyond Earth. You

85
00:04:59.399 --> 00:05:02.040
know how I keep urging you to look up. Here's why.

86
00:05:02.480 --> 00:05:06.399
A small asteroid named twenty twenty four RW one recently

87
00:05:06.399 --> 00:05:08.199
put on a show as it burned up in Earth's

88
00:05:08.199 --> 00:05:11.920
atmosphere above the Western Pacific Ocean near Luzon Island in

89
00:05:11.959 --> 00:05:16.199
the Philippines. Discovered just hours before impact by research technologist

90
00:05:16.240 --> 00:05:20.279
Jacqueline Fazecas with the NASA funded Catalina Sky Survey twenty

91
00:05:20.279 --> 00:05:23.160
twenty four, RW one was only the ninth asteroid to

92
00:05:23.160 --> 00:05:26.399
be spotted prior to its impact with our planet. The asteroid,

93
00:05:26.399 --> 00:05:29.519
which measured about three feet in diameter, made its fiery

94
00:05:29.639 --> 00:05:33.680
entrance at approximately twelve forty six pm Eastern time. Videos

95
00:05:33.720 --> 00:05:36.920
posted on social media captured a bright green fireball streaking

96
00:05:36.959 --> 00:05:40.199
across the sky, visible from the east coast of the Philippines.

97
00:05:40.800 --> 00:05:44.839
This dazzling display captivated onlookers and provided a stunning example

98
00:05:44.879 --> 00:05:47.920
of the forces at play in our solar system. NASA's

99
00:05:47.920 --> 00:05:51.600
Planetary Defense Coordination Office confirmed that the impact was detected

100
00:05:51.600 --> 00:05:55.600
by multiple sensors. This event underscores the critical importance of

101
00:05:55.600 --> 00:05:59.720
planetary defense, that is, the effort to detect, track, and

102
00:05:59.759 --> 00:06:03.160
putotentially mitigate near Earth objects that might pose a collision risk.

103
00:06:03.720 --> 00:06:06.839
The successful identification and monitoring of twenty twenty four are

104
00:06:07.040 --> 00:06:10.240
W one demonstrate the strides being made by global space

105
00:06:10.279 --> 00:06:14.439
agencies to keep our planet safe and speaking of looking up,

106
00:06:14.839 --> 00:06:18.160
September is shaping up to be an extraordinary month for skywatchers,

107
00:06:18.439 --> 00:06:22.439
so grab your telescopes and binoculars for some spectacular celestial events.

108
00:06:22.759 --> 00:06:25.680
First up, we have an incredible harvest supermoon eclipse on

109
00:06:25.720 --> 00:06:29.560
September seventeenth. This full moon, also known as the Harvest Moon,

110
00:06:30.079 --> 00:06:32.519
is extra special this year as it coincides with a

111
00:06:32.560 --> 00:06:35.879
partial lunar eclipse. As the moon rises for those on

112
00:06:35.920 --> 00:06:38.399
the West coast of the United States, you'll notice a

113
00:06:38.439 --> 00:06:41.680
subtle bite taken out of it. Check the timing locally,

114
00:06:41.759 --> 00:06:43.639
but it's set to be visible for most of the night.

115
00:06:44.240 --> 00:06:47.000
Even though the difference in size and brightness compared to

116
00:06:47.040 --> 00:06:49.680
an average full moon is hard to detect with the

117
00:06:49.759 --> 00:06:53.959
naked eye, the supermoon always provides an impressive sight, and

118
00:06:54.000 --> 00:06:56.600
that's just the beginning. All month long, you can catch

119
00:06:56.680 --> 00:07:00.279
views of five planets Venus, Saturn, Jupiter, Mars, and Mars Mercury.

120
00:07:00.879 --> 00:07:03.560
Venus will be hanging low in the western sky shortly

121
00:07:03.600 --> 00:07:07.000
after sunset, gradually climbing higher as we move into the

122
00:07:07.079 --> 00:07:10.120
later months of the year. Saturn will be visible all night,

123
00:07:10.319 --> 00:07:12.800
starting in the southeastern sky at dusk and setting in

124
00:07:12.800 --> 00:07:15.800
the west by dawn. Jupiter and Mars are both early

125
00:07:15.839 --> 00:07:19.680
morning delights, rising around midnight or a bit afterward. Keep

126
00:07:19.680 --> 00:07:22.800
an eye out for Mercury too visible during morning twilight.

127
00:07:22.839 --> 00:07:24.920
In the first week of September. For those with a

128
00:07:24.959 --> 00:07:28.959
clear eastern view, mark your calendars for a couple of

129
00:07:29.040 --> 00:07:32.720
key dates. On September sixteenth, the Moon will lead Saturn

130
00:07:32.759 --> 00:07:35.879
across the sky, an awe inspiring sight for anyone with

131
00:07:35.920 --> 00:07:39.600
a clear southeastern horizon, and the following night, as the

132
00:07:39.600 --> 00:07:43.360
Moon journeys through the Pleiades, fans of this star cluster

133
00:07:43.439 --> 00:07:45.759
will get to see the Moon passing right in front

134
00:07:45.759 --> 00:07:49.519
of it, a striking spectacle for sure. Another event to

135
00:07:49.519 --> 00:07:52.120
look forward to is the International Observe the Moonnight on

136
00:07:52.160 --> 00:07:55.879
September fourteenth. Whether you're attending a local event or observing

137
00:07:55.879 --> 00:07:59.439
from your backyard, it's a wonderful opportunity to appreciate our

138
00:07:59.439 --> 00:08:03.079
closest life lestial neighbor. This year's event is uniquely special,

139
00:08:03.480 --> 00:08:06.360
as we'll get to observe the Marius Hills, volcanic domes,

140
00:08:06.399 --> 00:08:10.199
and cones of lunar terrain under ideal lighting conditions. Last,

141
00:08:10.199 --> 00:08:13.000
but certainly not least, there's a new NASA spacecraft to

142
00:08:13.000 --> 00:08:16.000
watch for in the night sky, the Advanced Composite Solar

143
00:08:16.040 --> 00:08:19.879
Sale System or ACS three. This satellite, now equipped with

144
00:08:19.920 --> 00:08:22.959
thirty foot solar sales, will be testing new propulsion technologies.

145
00:08:23.480 --> 00:08:26.279
These highly reflective sales make the spacecraft almost as bright

146
00:08:26.319 --> 00:08:29.000
as serious, and you can track its passages using the

147
00:08:29.079 --> 00:08:32.120

has earned him a reputation for groundbreaking discoveries. Aboard the

154
00:08:57.879 --> 00:09:01.480
International Space Station. Today were diving into some of Pettitt's

155
00:09:01.480 --> 00:09:05.600
most inventive science of opportunity experiments. One of Pettit's fascinating

156
00:09:05.600 --> 00:09:09.600
investigations involved freezing ice in the microgravity of space. He

157
00:09:09.679 --> 00:09:12.799
observed that, unlike on Earth, where gravity causes trapped air

158
00:09:12.840 --> 00:09:15.799
to accumulate in one spot inside the ice cube, water

159
00:09:15.840 --> 00:09:19.879
freezes differently in microgravity. Using a minus ninety degree celsius

160
00:09:19.919 --> 00:09:23.559
freezer on board the ISS and polarizing light, Pettit was

161
00:09:23.600 --> 00:09:27.120
able to capture and study these differences. His findings provide

162
00:09:27.200 --> 00:09:30.759
valuable insights into the behavior of fluids and the physical

163
00:09:30.799 --> 00:09:33.759
principles at play in the absence of gravity. Not one

164
00:09:33.840 --> 00:09:36.759
to overlook daily rituals, Pettit also devised a solution for

165
00:09:36.840 --> 00:09:40.960
drinking beverages more conveniently in space. Traditional methods involve sipping

166
00:09:41.039 --> 00:09:43.960
through a straw from sealed bags, an approach that left

167
00:09:44.039 --> 00:09:47.639
much to be desired. Using overhead transparency film, he created

168
00:09:47.679 --> 00:09:51.000
the prototype for the capillary beverage or space cup. This

169
00:09:51.240 --> 00:09:54.679
ingenious cup exploits surface tension and container shape to imitate

170
00:09:54.720 --> 00:09:57.720
the effects of gravity, making it easier and more enjoyable

171
00:09:57.720 --> 00:10:02.639
to sit beverages. Pettit's curiosity extended to planetary formation too.

172
00:10:03.279 --> 00:10:07.000
Using materials such as table salt, sugar, and coffee grounds,

173
00:10:07.320 --> 00:10:11.600
he examined how tiny particles clumped together in microgravity, an

174
00:10:11.639 --> 00:10:15.639
early and crucial step in planetary formation. By placing these

175
00:10:15.639 --> 00:10:19.919
particulate mixtures in plastic bags, filling them with air, and

176
00:10:20.000 --> 00:10:24.879
shaking them, he demonstrated how particles naturally aggregate due to

177
00:10:24.960 --> 00:10:30.519
electrostatic forces. These simple, yet profound observations are helping scientists

178
00:10:30.639 --> 00:10:34.679
understand the fundamental processes that lead to planet formation. He

179
00:10:34.720 --> 00:10:38.360
didn't stop there. Pettit also explored orbital motion using knitting

180
00:10:38.440 --> 00:10:41.519
needles rubbed with paper to charge them electrically. He then

181
00:10:41.559 --> 00:10:45.720
observed water droplets orbiting the needles, providing a fascinating analogy

182
00:10:45.720 --> 00:10:49.120
to charge particles in Earth's magnetic field and offering potential

183
00:10:49.120 --> 00:10:53.159
applications for future spacecraft systems. One of Pettit's most visually

184
00:10:53.200 --> 00:10:58.559
stunning contributions has been his astrophotography. Utilizing various techniques like

185
00:10:58.639 --> 00:11:03.120
time exposure and multiple cameras, he has captured exquisite images

186
00:11:03.159 --> 00:11:06.240
of Earth and star trails from the unique vantage of

187
00:11:06.279 --> 00:11:10.039
the space station. These images not only contribute to scientific research,

188
00:11:10.080 --> 00:11:15.320
but also inspire public fascination with space exploration. From freezing

189
00:11:15.360 --> 00:11:20.279
ice to capturing cosmic photos, Pettit's inventive experiments have significantly

190
00:11:20.440 --> 00:11:24.600
enriched our understanding of space science, proving that sometimes the

191
00:11:24.600 --> 00:11:27.960
best discoveries come from a keen sense of curiosity and

192
00:11:28.000 --> 00:11:31.240
