Welcome to Astronomy Daily, your go-to source for the latest in space exploration and astronomy news. I'm Anna, and today we're diving into some groundbreaking stories, from the Parker Solar Probe's historic solar approach to a rare astronomical event to wrap up the year.
Highlights:
- Parker Solar Probe's Record-Breaking Pass: NASA's Parker Solar Probe has achieved a remarkable feat by completing its closest ever pass to the Sun, breaking its own record. On December 24, the spacecraft flew just 3.8 million miles from the solar surface at an astonishing speed of 430,000 miles per hour, making it the fastest human-made object in history. This mission marks humanity's first direct investigation of a star, offering unprecedented insights into the Sun's behavior.
- Blue Origin's New Glenn Milestones: Blue Origin has reached two significant milestones with its New Glenn rocket. The company completed a successful integrated hot fire test of the launch vehicle, and the FAA granted a commercial launch license. New Glenn's first flight will carry the Blue Ring Pathfinder, paving the way for national security space launch missions and potential government contracts.
- Rare Astronomical Event: Black Moon: As December comes to a close, stargazers can look forward to a rare Black Moon on December 30th. This second New Moon of the month offers perfect conditions for observing celestial objects, with Venus, Saturn, and Jupiter visible in the night sky alongside the winter constellations.
- Sun's Christmas Light Show: On December 25, the Sun unleashed four powerful solar flares in a synchronized event known as sympathetic solar flares. While the resulting coronal mass ejection is expected to pass north of Earth, scientists remain hopeful for future aurora displays as solar activity continues.
- Mars Sample Return Mission Redesign: NASA is set to announce a major redesign of the Mars Sample Return Mission in early January. This decision aims to address timeline and budget concerns, with the goal of returning Martian samples to Earth before human missions to the Red Planet begin.

00:00:00.160 --> 00:00:02.879
Welcome to Astronomy Daily, your source for the latest space

2
00:00:02.879 --> 00:00:05.879
in astronomy news. I'm your host, Anna, and today we've

3
00:00:05.879 --> 00:00:09.039
got an exciting lineup of stories from Parker Solar Probe's

4
00:00:09.080 --> 00:00:12.359
historic solar approach to a rare astronomical event closing out

5
00:00:12.359 --> 00:00:14.800
the year. There's certainly a lot going on even though

6
00:00:14.800 --> 00:00:18.399
it's holiday time, so let's get started with today's history

7
00:00:18.440 --> 00:00:24.000
making news. First, in a remarkable achievement, NASA's Parker Solar

8
00:00:24.039 --> 00:00:27.719
Probe has just successfully completed its closest ever pass to

9
00:00:27.760 --> 00:00:32.200
the Sun, breaking its own previous record. On December twenty fourth,

10
00:00:32.439 --> 00:00:35.880
the spacecraft flew an astounding three point eight million miles

11
00:00:35.880 --> 00:00:39.439
above the solar surface, hurtling through the solar atmosphere at

12
00:00:39.479 --> 00:00:42.439
a blazing speed of four hundred and thirty thousand miles

13
00:00:42.439 --> 00:00:45.719
per hour, faster than any human made object in history.

14
00:00:46.560 --> 00:00:49.840
The mission teams received confirmation late on December twenty sixth,

15
00:00:49.840 --> 00:00:52.640
when it phoned home so to speak, that the spacecraft

16
00:00:52.679 --> 00:00:56.479
had successfully survived this extreme encounter and is operating normally.

17
00:00:57.039 --> 00:01:00.200
This incredible feat wasn't just a one time event. It's

18
00:01:00.240 --> 00:01:03.960
the first of several planned passes at this distance, setting

19
00:01:04.079 --> 00:01:07.680
up the Probe for unprecedented scientific observations of our star.

20
00:01:08.760 --> 00:01:11.480
The spacecraft has spent the last six years preparing for

21
00:01:11.560 --> 00:01:15.599
this moment, using seven strategic flybys of Venus to gradually

22
00:01:15.599 --> 00:01:19.840
adjust its orbit. Following its final Venus fly by in November,

23
00:01:20.040 --> 00:01:23.439
Parker Solar Probe reached its optimal trajectory, which will bring

24
00:01:23.519 --> 00:01:26.560
it close to the Sun every three months, near enough

25
00:01:26.599 --> 00:01:30.359
to study mysterious solar processes, but maintaining a safe distance

26
00:01:30.400 --> 00:01:34.040
from the Sun's intense heat and radiation. To survive these

27
00:01:34.079 --> 00:01:37.959
close encounters, the probe relies on a sophisticated carbon foam

28
00:01:37.959 --> 00:01:42.040
shield that protects it from temperatures exceeding one million degrees

29
00:01:42.040 --> 00:01:46.280
fahrenheit in the solar corona. While the shield itself heats

30
00:01:46.359 --> 00:01:50.280
up to around one thousand, eight hundred degrees fahrenheit, it

31
00:01:50.439 --> 00:01:54.000
keeps the scientific instruments behind it at a comfortable room temperature.

32
00:01:54.920 --> 00:01:58.560
These close passes are already revolutionizing our understanding of the Sun.

33
00:01:59.239 --> 00:02:02.000
Previous approach have revealed that the outer boundary of the

34
00:02:02.040 --> 00:02:06.560
corona is more complex than expected, with unexpected wrinkles and valleys.

35
00:02:07.359 --> 00:02:10.439
The probe has also identified the origin of important solar

36
00:02:10.439 --> 00:02:14.280
wind structures and is helping scientists better understand how the

37
00:02:14.280 --> 00:02:17.879
solar wind accelerates as it leaves the Sun. This mission

38
00:02:17.919 --> 00:02:22.319
represents a historic moment in space exploration, marking humanity's first

39
00:02:22.360 --> 00:02:25.719
direct investigation of a star, and promises to unlock new

40
00:02:25.759 --> 00:02:28.560
mysteries about our son's behavior and its effects throughout the

41
00:02:28.560 --> 00:02:33.439
Solar System. Moving on, Blue Origin has just hit two

42
00:02:33.439 --> 00:02:36.680
major milestones in their journey towards launching their massive new

43
00:02:36.680 --> 00:02:41.080
Glen rocket. The company successfully completed an integrated hot fire

44
00:02:41.120 --> 00:02:44.759
test of the fully assembled launch vehicle at Launch Complex

45
00:02:44.840 --> 00:02:49.439
thirty six in Cape Canaveral, Florida. During this crucial twenty

46
00:02:49.439 --> 00:02:53.919
four second test, all seven B four engines operated flawlessly,

47
00:02:54.520 --> 00:02:58.439
including thirteen seconds at full thrust. This wasn't just a

48
00:02:58.479 --> 00:03:02.400
simple engine test. The demonstration involved the complete flight vehicle,

49
00:03:02.719 --> 00:03:06.240
including both first and second stages, along with test versions

50
00:03:06.280 --> 00:03:09.879
of the payload, faring and various other components. Teams conducted

51
00:03:09.960 --> 00:03:13.719
multiple days of preparation, including tanking tests with both liquid

52
00:03:13.800 --> 00:03:17.199
natural gas and liquid oxygen in the first stage and

53
00:03:17.280 --> 00:03:21.360
liquid hydrogen and oxygen in the second stage. Adding to

54
00:03:21.400 --> 00:03:25.879
this technical achievement, the Federal Aviation Administration has granted Blue

55
00:03:25.879 --> 00:03:28.800
Origin a Part four hundred and fifty Commercial Launch License

56
00:03:28.840 --> 00:03:32.800
for New Glen. This five year authorization marks a significant

57
00:03:32.840 --> 00:03:37.199
regulatory milestone, clearing the way for actual flight operations. New

58
00:03:37.240 --> 00:03:40.319
Glen stands an impressive three hundred and twenty one feet tall,

59
00:03:40.520 --> 00:03:43.680
with a first stage designed to land propulsively, similar to

60
00:03:43.719 --> 00:03:47.919
SpaceX's Falcon nine. Those seven B four engines that performed

61
00:03:47.919 --> 00:03:50.120
so well in the test are the same ones currently

62
00:03:50.159 --> 00:03:54.960
powering United Launch Alliance's Vulcan rocket, giving Blue Origin valuable

63
00:03:54.960 --> 00:03:58.960
flight experience with their engine design before New Glen's first launch.

64
00:04:00.000 --> 00:04:02.240
When New Glen does take flight, it will carry the

65
00:04:02.240 --> 00:04:05.680
Blue Ring Pathfinder as its first payload. This mission will

66
00:04:05.680 --> 00:04:08.360
serve as a crucial step in certifying the rocket for

67
00:04:08.439 --> 00:04:12.560
national security space launch missions, potentially opening the door to

68
00:04:12.680 --> 00:04:17.920
lucrative government contracts. With multiple vehicles already in production and

69
00:04:18.000 --> 00:04:22.279
a growing manifest of commercial and government customers, Blue Origin

70
00:04:22.360 --> 00:04:25.920
appears well positioned to join the ranks of major launch

71
00:04:25.959 --> 00:04:29.279
providers in the near future. You know how I keep

72
00:04:29.319 --> 00:04:31.519
telling you to get outside and look up, Well, it's

73
00:04:31.560 --> 00:04:35.120
about to pay off. Stargazers and astronomy enthusiasts are in

74
00:04:35.160 --> 00:04:37.120
for a treat as we approach the end of December

75
00:04:37.519 --> 00:04:40.920
with a rare astronomical phenomenon known as a black moon,

76
00:04:41.399 --> 00:04:44.360
set to occur on December thirtieth at five twenty seven

77
00:04:44.439 --> 00:04:49.079
pm Eastern Time. While the term isn't officially recognized by astronomers,

78
00:04:49.480 --> 00:04:51.839
it refers to the second new moon occurring within a

79
00:04:51.879 --> 00:04:55.600
single calendar month, similar to how a blue moon describes

80
00:04:55.639 --> 00:04:58.879
a second full moon in a month. During a new moon,

81
00:04:59.240 --> 00:05:02.519
the Sun and moon and share the same celestial longitude,

82
00:05:02.519 --> 00:05:05.639
meaning the illuminated side of the Moon faces away from Earth,

83
00:05:06.079 --> 00:05:09.439
making it invisible to observers. While we can't see the

84
00:05:09.439 --> 00:05:13.199
moon itself. This absence of moonlight creates perfect conditions for

85
00:05:13.279 --> 00:05:16.639
viewing other celestial objects. The timing couldn't be better for

86
00:05:16.680 --> 00:05:20.399
winter stargazing in North America, where the typically drier air

87
00:05:20.839 --> 00:05:25.000
offers exceptional viewing conditions through telescopes. The night sky will

88
00:05:25.000 --> 00:05:29.480
be particularly active, with several planets visible to observers. Venus

89
00:05:29.519 --> 00:05:32.600
and Saturn will grace the southwestern sky in the evening hours,

90
00:05:33.000 --> 00:05:36.600
while Jupiter will be prominently positioned in the east, appearing

91
00:05:36.639 --> 00:05:41.040
near the bright star Aldebaran in Taurus. The winter constellations

92
00:05:41.040 --> 00:05:44.120
will be on full display, with Oriyan the Hunter taking

93
00:05:44.160 --> 00:05:47.439
center stage in the eastern sky. Look for the distinctive

94
00:05:47.480 --> 00:05:51.279
three stars of Orion's belt and the bright stars Beetlejuice,

95
00:05:51.279 --> 00:05:54.759
and Rigel marking his shoulder and foot. The hyed star

96
00:05:54.839 --> 00:05:57.759
cluster forming the face of Taurus the Bull will be

97
00:05:57.839 --> 00:06:01.600
visible above Orion, while Syrious, the brightest star in our

98
00:06:01.680 --> 00:06:05.600
night sky, will shine brilliantly as part of Canis Major below.

99
00:06:06.199 --> 00:06:08.879
For those willing to stay up later, Leo the Lion

100
00:06:08.920 --> 00:06:11.519
will rise in the east, marked by the bright star

101
00:06:11.600 --> 00:06:15.720
Regulus and its distinctive sickle shaped pattern of stars forming

102
00:06:15.759 --> 00:06:20.040
the Lion's main This moonless night offers an exceptional opportunity

103
00:06:20.079 --> 00:06:24.319
to observe these celestial wonders in all their glory. Enjoy

104
00:06:25.920 --> 00:06:28.879
in more news today about our Star. The Sun put

105
00:06:28.920 --> 00:06:30.639
on quite a Christmas light show this year, with our

106
00:06:30.680 --> 00:06:33.920
Star unleashing four powerful solar flares within just two and

107
00:06:33.920 --> 00:06:37.120
a half hours on December twenty fifth. The most significant

108
00:06:37.160 --> 00:06:40.639
of these eruptions was classified as an M seven three flare,

109
00:06:40.879 --> 00:06:43.639
bursting forth from a region known as AR three thousand,

110
00:06:43.720 --> 00:06:47.079
nine hundred thirty eight at ten fifteen pm Eastern Time.

111
00:06:47.800 --> 00:06:51.800
These synchronized explosions, known as sympathetic solar flares are quite

112
00:06:51.879 --> 00:06:56.079
rare and occurred across three different sunspot regions, AR three thousand,

113
00:06:56.199 --> 00:07:00.199
nine hundred thirty eight, AR three thousand, nine hundred thirty three,

114
00:07:00.319 --> 00:07:03.480
and AR three thy nine hundred and thirty six. What

115
00:07:03.600 --> 00:07:07.480
makes this event particularly interesting is that despite being spatially

116
00:07:07.519 --> 00:07:11.360
separated on the Sun's surface, these regions were actually connected

117
00:07:11.399 --> 00:07:15.639
by invisible magnetic loops, causing them to erupt in concert

118
00:07:15.800 --> 00:07:20.360
like a cosmic chain reaction. The National Oceanic and Atmospheric

119
00:07:20.399 --> 00:07:25.839
Administration's Solar Monitoring satellites captured these spectacular eruptions, which resembled

120
00:07:25.920 --> 00:07:29.600
festive twinkling lights on a cosmic scale. While these flares

121
00:07:29.639 --> 00:07:34.000
were impressive, the resulting coronal mass ejection that's the supercharged

122
00:07:34.040 --> 00:07:37.360
plasma bubble that gets hurled into space, is expected to

123
00:07:37.439 --> 00:07:40.519
pass just north of Earth, meaning will likely miss out

124
00:07:40.519 --> 00:07:44.399
on any Aurora displays this time. However, there's still hope

125
00:07:44.399 --> 00:07:48.680
for some celestial fireworks before the year ends. Scientists are

126
00:07:48.680 --> 00:07:51.439
confident that the Sun will maintain its active state through

127
00:07:51.480 --> 00:07:55.199
the remainder of twenty twenty four. All it takes is

128
00:07:55.240 --> 00:07:57.959
one well aimed, powerful flare to treat us to a

129
00:07:58.000 --> 00:08:01.319
spectacular Aurora show as we approach the new year, so

130
00:08:01.399 --> 00:08:05.120
keep looking up. These Christmas flares serve as another reminder

131
00:08:05.160 --> 00:08:08.839
of our star's incredible power and unpredictability as we continue

132
00:08:08.879 --> 00:08:12.800
to monitor and study its dynamic behavior. The Sun's increasing

133
00:08:12.839 --> 00:08:17.040
activity gives scientists valuable opportunities to better understand these powerful

134
00:08:17.079 --> 00:08:21.680
solar phenomena and their potential impacts on Earth. In a

135
00:08:21.720 --> 00:08:26.279
significant development for Mars exploration, NASA Administrator Bill Nelson has

136
00:08:26.319 --> 00:08:29.720
revealed that a major announcement about the Mars Sample Return

137
00:08:29.800 --> 00:08:34.720
mission redesign is coming in early January. This highly anticipated

138
00:08:34.720 --> 00:08:37.960
decision aims to address the mounting concerns over the project's

139
00:08:37.960 --> 00:08:41.799
timeline and budget that have emerged in recent months. The

140
00:08:41.840 --> 00:08:45.879
original mission design, carrying an estimated price tag of eleven

141
00:08:45.919 --> 00:08:49.360
billion dollars and a sample return date of twenty forty,

142
00:08:49.919 --> 00:08:54.720
was deemed unsustainable by NASA leadership. Nelson emphasized that this

143
00:08:54.840 --> 00:08:59.440
timeline would conflict with NASA's broader Mars exploration goals, particularly

144
00:08:59.480 --> 00:09:01.960
since the agency plans to have astronauts on the red

145
00:09:02.000 --> 00:09:05.759
planet by the two thousand forties. The redesign effort has

146
00:09:05.799 --> 00:09:09.759
taken an innovative approach by actively involving private industry partners

147
00:09:10.200 --> 00:09:15.519
alongside NASA's traditional centers. Early indications suggest this strategy is

148
00:09:15.600 --> 00:09:20.279
yielding promising results, with proposals that could significantly reduce costs

149
00:09:20.320 --> 00:09:24.759
and accelerate the mission timeline. This shift in strategy comes

150
00:09:24.799 --> 00:09:28.440
after a comprehensive review by an independent review board highlighted

151
00:09:28.480 --> 00:09:32.559
serious concerns about the project's scope and feasibility. The mission's

152
00:09:32.559 --> 00:09:37.559
complexity is substantial, involving multiple spacecraft components, including a lander,

153
00:09:37.879 --> 00:09:41.120
a rocket to launch samples from Mars's surface, and an

154
00:09:41.279 --> 00:09:45.080
orbiter to transport the samples back to Earth. The urgency

155
00:09:45.120 --> 00:09:47.759
behind this redesign is driven by the fact that the

156
00:09:47.759 --> 00:09:52.840
Perseverance Rover is already on Mars, actively collecting and caching samples.

157
00:09:53.360 --> 00:09:57.279
These precious materials represent an unprecedented opportunity to study Mars's

158
00:09:57.320 --> 00:10:01.000
geological history and potential signs of ancient life, making the

159
00:10:01.039 --> 00:10:04.360
success of the sample return mission crucial for our understanding

160
00:10:04.399 --> 00:10:08.159
of the Red planet. NASA's leadership is optimistic that the

161
00:10:08.200 --> 00:10:12.279
new industry involved approach will provide a more practical path forward,

162
00:10:12.840 --> 00:10:15.679
ensuring these valuable Martian samples make it back to Earth

163
00:10:15.720 --> 00:10:19.480
for study before human missions begin The upcoming announcement is

164
00:10:19.519 --> 00:10:23.360
expected to detail significant changes to the mission architecture while

165
00:10:23.399 --> 00:10:28.600
maintaining its core scientific objectives. And that's it for today.

166
00:10:29.360 --> 00:10:32.559
