<v Speaker 1>with our soothing Bedtime Astronomie podcast. Each episode offers a

3
00:00:12.359 --> 00:00:16.320
<v Speaker 1>gentle journey through the stars, planets, and beyond, perfect for

4
00:00:16.399 --> 00:00:20.239
<v Speaker 1>unwinding after a long day. Let's travel through the mysteries

5
00:00:20.239 --> 00:00:22.440
<v Speaker 1>of the universe as you drift off into a peaceful

6
00:00:22.480 --> 00:00:29.600
<v Speaker 1>slumber under the night sky. Upcoming space launches New Glen

7
00:00:29.640 --> 00:00:35.880
<v Speaker 1>and Starship seven Blue Origin's New Glen pre launch overview.

8
00:00:37.799 --> 00:00:42.200
<v Speaker 1>Blue Origin, the space company founded by Jeff Bezos, has

9
00:00:42.240 --> 00:00:45.759
<v Speaker 1>been developing the New Glen Rocket, a heavy lift vehicle

10
00:00:45.880 --> 00:00:49.679
<v Speaker 1>named after the first American to orbit Earth, John Glenn.

11
00:00:50.920 --> 00:00:54.759
<v Speaker 1>This rocket represents a significant step for Blue Origin as

12
00:00:54.759 --> 00:00:58.159
<v Speaker 1>it ventures into the realm of orbital launches, aiming to

13
00:00:58.200 --> 00:01:02.159
<v Speaker 1>disrupt the dominance of competitors like SpaceX in the commercial

14
00:01:02.200 --> 00:01:06.359
<v Speaker 1>space sector. The New Glen Rocket is designed to be

15
00:01:06.439 --> 00:01:10.519
<v Speaker 1>partially reusable, with a first stage that lands vertically on

16
00:01:10.560 --> 00:01:14.799
<v Speaker 1>a sea platform, much like SpaceX's Falcon nine, but it's

17
00:01:14.879 --> 00:01:19.400
<v Speaker 1>engineered with the capability to fly humans, reflecting Blue Origin's

18
00:01:19.480 --> 00:01:24.040
<v Speaker 1>long term vision of making space more accessible for various missions,

19
00:01:24.079 --> 00:01:29.359
<v Speaker 1>including human spaceflight. The rocket stands at an impressive three

20
00:01:29.439 --> 00:01:33.640
<v Speaker 1>hundred and twenty feet tall ninety eight meters dwarfing its

21
00:01:33.640 --> 00:01:38.000
<v Speaker 1>suborbital counterpart, New Shepherd, and is built to accommodate a

22
00:01:38.040 --> 00:01:41.519
<v Speaker 1>wide range of payloads with its seven meter wide firing,

23
00:01:41.920 --> 00:01:46.359
<v Speaker 1>which is larger than many competitors in the industry. The

24
00:01:46.400 --> 00:01:50.159
<v Speaker 1>first stage is powered by seven B four engines which

25
00:01:50.239 --> 00:01:54.840
<v Speaker 1>use liquid oxygen and liquefied natural gas, offering a cleaner,

26
00:01:55.280 --> 00:02:01.319
<v Speaker 1>more sustainable alternative to traditional kerosene based engines. These engines

27
00:02:01.439 --> 00:02:06.599
<v Speaker 1>collectively produce around three eight million pounds of thrust at

28
00:02:06.640 --> 00:02:09.800
<v Speaker 1>sea level, making New Glen one of the most powerful

29
00:02:09.879 --> 00:02:14.719
<v Speaker 1>rockets in operation. The second stage uses two B three

30
00:02:14.879 --> 00:02:19.680
<v Speaker 1>U engines optimized for vacuum conditions, which together produced two

31
00:02:19.840 --> 00:02:25.080
<v Speaker 1>hundred and forty thousand pounds of thrust. The rocket's payload

32
00:02:25.120 --> 00:02:29.159
<v Speaker 1>capabilities are notable, with the capacity to send forty five

33
00:02:29.280 --> 00:02:33.039
<v Speaker 1>metric tons to low Earth orbit and thirteen metric tons

34
00:02:33.080 --> 00:02:37.639
<v Speaker 1>to geostationary transfer orbit, positioning it as a strong contender

35
00:02:37.719 --> 00:02:42.960
<v Speaker 1>for both commercial and governmental launches. Development of New Glen

36
00:02:43.000 --> 00:02:47.080
<v Speaker 1>began in earnest around twenty twelve, with the public unveiling

37
00:02:47.120 --> 00:02:51.479
<v Speaker 1>of its design in two thousand sixteen. The journey to

38
00:02:51.560 --> 00:02:55.400
<v Speaker 1>its first launch was marked by delays. Initially targeting at

39
00:02:55.439 --> 00:02:59.319
<v Speaker 1>twenty twenty debut, but faced with challenges such as engine

40
00:02:59.319 --> 00:03:05.879
<v Speaker 1>development is These aspirations were repeatedly pushed back. However, with

41
00:03:06.000 --> 00:03:10.199
<v Speaker 1>rigorous testing and milestones like the successful hot fire test

42
00:03:10.280 --> 00:03:13.919
<v Speaker 1>of all seven four engines in December twenty twenty four,

43
00:03:14.319 --> 00:03:18.719
<v Speaker 1>Blue Origin has been pushing forward. The maiden flight of

44
00:03:18.759 --> 00:03:22.360
<v Speaker 1>New Glen, dubbed in G one, has been scheduled for

45
00:03:22.439 --> 00:03:26.840
<v Speaker 1>no earlier than January thirteenth, twenty twenty five, with a

46
00:03:26.919 --> 00:03:33.039
<v Speaker 1>three hour launch window opening at one am BST. This

47
00:03:33.159 --> 00:03:36.400
<v Speaker 1>mission will not deploy a satellite, but will instead carry

48
00:03:36.439 --> 00:03:40.240
<v Speaker 1>the Blue Ring Pathfinder, a test version of Blue Origin's

49
00:03:40.280 --> 00:03:45.560
<v Speaker 1>future space logistics platform, to validate its communication and operational

50
00:03:45.639 --> 00:03:50.199
<v Speaker 1>systems from orbit to ground. The launch from Cape Canaveral

51
00:03:50.280 --> 00:03:54.280
<v Speaker 1>Space four station's Launch Complex thirty six marks the first

52
00:03:54.319 --> 00:03:57.240
<v Speaker 1>time this pad has been used in nearly two decades,

53
00:03:57.680 --> 00:04:03.120
<v Speaker 1>highlighting Blue Origin's investment in a time space infrastructure. Despite

54
00:04:03.199 --> 00:04:08.680
<v Speaker 1>the anticipation surrounding this launch, Blue Origin has tempered expectations,

55
00:04:08.719 --> 00:04:12.000
<v Speaker 1>acknowledging that while the primary goal is to reach orbit,

56
00:04:12.520 --> 00:04:17.639
<v Speaker 1>success is not guaranteed. The company aims to recover the

57
00:04:17.680 --> 00:04:21.120
<v Speaker 1>first stage on a landing platform named Jacqueline in the

58
00:04:21.199 --> 00:04:25.680
<v Speaker 1>Atlantic Ocean, an ambitious goal for a first flight, underlining

59
00:04:25.720 --> 00:04:30.000
<v Speaker 1>their commitment to reusability to reduce the costs and environmental

60
00:04:30.040 --> 00:04:34.959
<v Speaker 1>impact of spaceflight. This mission's outcome will be crucial for

61
00:04:35.040 --> 00:04:39.079
<v Speaker 1>Blue Origin, not only proving the rocket's capabilities, but also

62
00:04:39.199 --> 00:04:44.000
<v Speaker 1>setting the stage for future launches, including national security missions,

63
00:04:44.399 --> 00:04:49.600
<v Speaker 1>Amazon's Project Kuyper, satellite deployments, and even supporting the construction

64
00:04:49.720 --> 00:04:55.480
<v Speaker 1>of Blue Origins proposed commercial space station orbital REEF. The

65
00:04:55.560 --> 00:04:58.720
<v Speaker 1>launch of New Glen is not just a technical milestone,

66
00:04:58.800 --> 00:05:03.240
<v Speaker 1>but a symbolic one, showcasing Blue Origin's readiness to compete

67
00:05:03.319 --> 00:05:05.759
<v Speaker 1>in the orbital launch market and to live up to

68
00:05:05.879 --> 00:05:09.399
<v Speaker 1>Jeff Bezos's vision of a future where heavy industry is

69
00:05:09.480 --> 00:05:13.800
<v Speaker 1>moved off Earth, preserving our planet while expanding human presence

70
00:05:13.879 --> 00:05:24.279
<v Speaker 1>in space. Starship Flight seven pre launch overview. The anticipation

71
00:05:24.439 --> 00:05:28.839
<v Speaker 1>for Starship Flight seven has been building, with SpaceX targeting

72
00:05:28.879 --> 00:05:33.319
<v Speaker 1>a launch date of January fifteenth, twenty twenty five. After

73
00:05:33.439 --> 00:05:36.879
<v Speaker 1>several delays attributed to weather conditions and the need for

74
00:05:37.000 --> 00:05:42.160
<v Speaker 1>final preparations. This seventh test flight of the Starship launch

75
00:05:42.240 --> 00:05:46.439
<v Speaker 1>system is not just another step in SpaceX's iterative process,

76
00:05:46.560 --> 00:05:49.639
<v Speaker 1>but a significant leap towards realizing the vision of a

77
00:05:49.680 --> 00:05:54.240
<v Speaker 1>fully reusable spacecraft capable of transporting humans and cargo to

78
00:05:54.399 --> 00:05:59.959
<v Speaker 1>destinations like the Moon, Mars, and beyond. The vehicle for FIS.

79
00:06:00.079 --> 00:06:04.000
<v Speaker 1>This mission combines a Block two Starship upper stage meln

80
00:06:04.040 --> 00:06:07.399
<v Speaker 1>as Ship thirty three with a Block one super heavy

81
00:06:07.439 --> 00:06:12.839
<v Speaker 1>booster Booster fourteen, illustrating both the evolution and the continuity

82
00:06:12.879 --> 00:06:18.000
<v Speaker 1>of SpaceX's development strategy. The journey to this launch has

83
00:06:18.040 --> 00:06:23.439
<v Speaker 1>been one of meticulous preparation and innovation. Ship thirty three,

84
00:06:23.920 --> 00:06:27.639
<v Speaker 1>the first of its kind and operational terms, introduces a

85
00:06:27.720 --> 00:06:33.519
<v Speaker 1>suite of upgrades over its predecessors. Its forward flaps, critical

86
00:06:33.560 --> 00:06:37.079
<v Speaker 1>for steering during re entry, have been redesigned to reduce

87
00:06:37.160 --> 00:06:42.120
<v Speaker 1>their exposure to the extreme heat of atmospheric reentry. These

88
00:06:42.199 --> 00:06:45.600
<v Speaker 1>flaps are not only smaller, but also positioned closer to

89
00:06:45.680 --> 00:06:48.800
<v Speaker 1>the tip of the vehicle, which reduces the complexity of

90
00:06:48.839 --> 00:06:54.800
<v Speaker 1>the underlying mechanisms and simplifies the protective tiling. This design

91
00:06:54.920 --> 00:06:57.920
<v Speaker 1>change aims to enhance the survival rate of the ship

92
00:06:57.959 --> 00:07:02.199
<v Speaker 1>through the re entry phase that has historically been challenging

93
00:07:02.279 --> 00:07:08.720
<v Speaker 1>for Starship prototypes. Moreover, the avionics of Ship thirty three

94
00:07:08.879 --> 00:07:13.839
<v Speaker 1>have undergone a complete overhaul. A more powerful flight computer

95
00:07:14.040 --> 00:07:17.079
<v Speaker 1>now resides at the heart of the ship's control systems,

96
00:07:17.480 --> 00:07:23.279
<v Speaker 1>complemented by integrated antennas that combine starlink GNSS and backup

97
00:07:23.399 --> 00:07:29.120
<v Speaker 1>RF communication functions. This setup promises not only better navigation,

98
00:07:29.360 --> 00:07:32.720
<v Speaker 1>but also real time streaming of high definition video and

99
00:07:32.759 --> 00:07:39.759
<v Speaker 1>telemetry data, offering unprecedented visibility into the spacecraft's performance. The

100
00:07:39.879 --> 00:07:45.639
<v Speaker 1>avionics upgrade extends to inertial navigation, star tracking sensors, and

101
00:07:45.720 --> 00:07:50.279
<v Speaker 1>smart batteries, ensuring that power and data are efficiently managed

102
00:07:50.319 --> 00:07:55.000
<v Speaker 1>across the vehicle. The propulsion system of Ship thirty three

103
00:07:55.160 --> 00:08:00.279
<v Speaker 1>has also seen significant enhancements. There's a twenty five percent

104
00:08:00.399 --> 00:08:04.399
<v Speaker 1>increase in propellant volume, made possible by a redesign of

105
00:08:04.439 --> 00:08:07.800
<v Speaker 1>the fuel feed line system for the vacuum raptor engines,

106
00:08:08.199 --> 00:08:12.399
<v Speaker 1>alongside vacuum jacketing of feed lines to minimize heat loss.

107
00:08:13.680 --> 00:08:17.920
<v Speaker 1>These changes are pivotal for extending mission durations and increasing

108
00:08:17.959 --> 00:08:22.199
<v Speaker 1>the payload capacity, setting the stage for more ambitious missions

109
00:08:22.240 --> 00:08:27.240
<v Speaker 1>in the near future. Starship Flight seven's mission profile is

110
00:08:27.319 --> 00:08:32.720
<v Speaker 1>perhaps the most ambitious yet for the first time, SpaceX

111
00:08:32.759 --> 00:08:36.879
<v Speaker 1>will attempt to deploy payloads in space, albeit with Starlink

112
00:08:36.919 --> 00:08:42.960
<v Speaker 1>simulator satellites. B Simulators similar in size and weight to

113
00:08:43.039 --> 00:08:47.080
<v Speaker 1>the next generation Starlink satellites will be deployed to test

114
00:08:47.120 --> 00:08:52.960
<v Speaker 1>the Starship's payload deployment capabilities. The simulators will follow a

115
00:08:53.000 --> 00:08:57.679
<v Speaker 1>suborbital trajectory re entering and splashing down in the Indian Ocean,

116
00:08:58.080 --> 00:09:02.720
<v Speaker 1>providing critical data onto play oloinment mechanisms, re entry dynamics,

117
00:09:03.159 --> 00:09:07.799
<v Speaker 1>and the behavior of satellites. During these phases, bi flight

118
00:09:07.919 --> 00:09:11.720
<v Speaker 1>will also see the testing of new thermal protection systems,

119
00:09:11.759 --> 00:09:15.759
<v Speaker 1>with Starship deliberately missing some heat shield tiles to observe

120
00:09:15.879 --> 00:09:20.399
<v Speaker 1>how alternative materials and designs perform under the extreme conditions

121
00:09:20.399 --> 00:09:26.440
<v Speaker 1>of re entry. The super heavy booster Booster fourteen comes

122
00:09:26.480 --> 00:09:30.559
<v Speaker 1>with its own set of challenges and objectives. One of

123
00:09:30.600 --> 00:09:34.840
<v Speaker 1>the Raptor engines on this booster has previously flown, marking

124
00:09:34.879 --> 00:09:38.919
<v Speaker 1>the first instance of engine reuse in the Starship program.

125
00:09:39.639 --> 00:09:43.799
<v Speaker 1>This step towards reusability is crucial for reducing costs and

126
00:09:43.919 --> 00:09:50.320
<v Speaker 1>increasing the frequency of launches. After stage separation, Booster fourteen

127
00:09:50.440 --> 00:09:53.120
<v Speaker 1>will attempt to return to the launch site where it

128
00:09:53.159 --> 00:09:56.080
<v Speaker 1>will be caught by the chopstick arms of the launch tower,

129
00:09:56.480 --> 00:10:01.840
<v Speaker 1>a maneuver that was successfully demonstrated in a previous This

130
00:10:02.080 --> 00:10:06.080
<v Speaker 1>catch not only signifies progress and reusability, but also in

131
00:10:06.080 --> 00:10:10.639
<v Speaker 1>the rapid turnaround of launch hardware. The flight will further

132
00:10:10.720 --> 00:10:14.759
<v Speaker 1>test in space engine relight capabilities with one of Starship's

133
00:10:14.840 --> 00:10:18.960
<v Speaker 1>Raptor engines, aiming to validate the vehicle's ability to perform

134
00:10:19.120 --> 00:10:23.279
<v Speaker 1>orbital maneuvers or adjust its trajectory for precise landings or

135
00:10:23.360 --> 00:10:28.919
<v Speaker 1>rendezvous in space. The data from these tests, streamed back

136
00:10:29.000 --> 00:10:33.559
<v Speaker 1>via starlink, will allow SpaceX engineers to refine designs and

137
00:10:33.679 --> 00:10:39.320
<v Speaker 1>operational procedures learning from each second of flight. This mission,

138
00:10:39.840 --> 00:10:45.600
<v Speaker 1>set for January fifteenth, twenty twenty five, from Starbase, Texas,

139
00:10:46.120 --> 00:10:51.279
<v Speaker 1>encapsulates SpaceX's philosophy of rapid iteration, where each flight builds

140
00:10:51.360 --> 00:10:54.840
<v Speaker 1>upon the last, pushing the boundaries of what's possible in

141
00:10:54.879 --> 00:11:00.000
<v Speaker 1>space exploration and transportation. The live streaming of the EVAs,

142
00:11:00.679 --> 00:11:04.840
<v Speaker 1>coupled with the comprehensive data collection, will not only captivate

143
00:11:04.960 --> 00:11:09.720
<v Speaker 1>audiences worldwide, but also contribute significantly to the scientific and

144
00:11:09.840 --> 00:11:15.759
<v Speaker 1>engineering community's understanding of spacecraft dynamics, re entry, processes and

145
00:11:15.840 --> 00:11:21.919
<v Speaker 1>the practicalities of space based operations. Starship Flight seven, with

146
00:11:22.039 --> 00:11:26.000
<v Speaker 1>all its complexities and innovations, is more than a test flight.

147
00:11:26.559 --> 00:11:29.159
<v Speaker 1>It's a bold statement of intent for the future of

148
00:11:29.240 --> 00:11:33.200
<v Speaker 1>space travel, aimed at making the vastness of space accessible

149
00:11:33.320 --> 00:12:52.440
<v Speaker 1>and routine to do before
