00:00:00 --> 00:00:03 Anna: Welcome to Astronomy Daily, your
00:00:03 --> 00:00:06 regular update on everything happening in the
00:00:06 --> 00:00:08 cosmos. I'm Anna.
00:00:08 --> 00:00:11 Avery: And I'm Avery. We've got a jam packed episode
00:00:11 --> 00:00:13 today, starting with some big news from
00:00:13 --> 00:00:13 SpaceX.
00:00:14 --> 00:00:16 Anna: Uh, very big indeed. And the whole starship
00:00:16 --> 00:00:19 team and SpaceX in general need to be
00:00:19 --> 00:00:20 congratulated.
00:00:20 --> 00:00:22 Avery: That's right, Anna. SpaceX today made
00:00:22 --> 00:00:24 headlines with its highly successful
00:00:24 --> 00:00:27 suborbital mission of the final version 2
00:00:27 --> 00:00:30 Starship Super super heavy rocket. This
00:00:30 --> 00:00:32 incredible flight involved crucial testing of
00:00:32 --> 00:00:35 its heat shield and a simulated deorbit
00:00:35 --> 00:00:38 burn, marking a significant step forward.
00:00:38 --> 00:00:41 Anna: Indeed Avery, this suborbital flight
00:00:41 --> 00:00:44 of the final version 2 Starship Super
00:00:44 --> 00:00:47 Heavy was a resounding success. The
00:00:47 --> 00:00:49 heat shield test was flawless and the
00:00:49 --> 00:00:52 simulated deorbit burn performed
00:00:52 --> 00:00:54 exactly as planned. This
00:00:54 --> 00:00:56 incredible achievement paves the way for
00:00:56 --> 00:00:59 SpaceX to now move to version three
00:00:59 --> 00:01:02 for orbital missions, which is absolutely
00:01:02 --> 00:01:05 critical for programs like NASA's Artemis.
00:01:05 --> 00:01:07 A key technological hurdle for those
00:01:07 --> 00:01:10 ambitious missions will be in orbit
00:01:10 --> 00:01:13 propellant transfer. And this success brings
00:01:13 --> 00:01:14 that closer to reality.
00:01:15 --> 00:01:18 Avery: It's truly a testament to SpaceX's
00:01:18 --> 00:01:20 audacious approach to rocket development.
00:01:20 --> 00:01:23 This highly successful flight unequivocally
00:01:23 --> 00:01:26 validates their iterative test, learn
00:01:26 --> 00:01:29 and iterate philosophy. Unlike traditional
00:01:29 --> 00:01:31 aerospace programs that might spend years on
00:01:31 --> 00:01:34 ground testing, SpaceX gathers
00:01:34 --> 00:01:36 invaluable data from each flight,
00:01:36 --> 00:01:39 rapidly advancing the Starship program. The
00:01:39 --> 00:01:42 Starship system is designed to be fully
00:01:42 --> 00:01:44 reusable, a uh, game changer for reducing
00:01:44 --> 00:01:47 launch costs and enabling large scale
00:01:47 --> 00:01:50 missions to the moon and Mars. The sheer
00:01:50 --> 00:01:52 scale of Starship, beyond being the largest
00:01:52 --> 00:01:54 and most powerful rocket ever built,
00:01:55 --> 00:01:57 presents unprecedented engineering
00:01:57 --> 00:01:59 challenges. And this successful suborbital
00:01:59 --> 00:02:02 test is a crucial step in pushing the
00:02:02 --> 00:02:04 boundaries of what's possible in space
00:02:04 --> 00:02:06 transportation towards orbital missions.
00:02:07 --> 00:02:09 Anna: The sheer scale of Starship being the
00:02:09 --> 00:02:12 largest and most powerful rocket ever built
00:02:13 --> 00:02:15 truly cannot be overstated. When fully
00:02:15 --> 00:02:18 stacked, it stands nearly 400ft
00:02:18 --> 00:02:21 tall, dwarfing even the Saturn V rockets
00:02:21 --> 00:02:24 of the Apollo era. Its this immense capacity
00:02:24 --> 00:02:27 is what makes it so revolutionary. It's not
00:02:27 --> 00:02:29 just about reaching orbit, it's about
00:02:29 --> 00:02:32 delivering massive payloads, hundreds of
00:02:32 --> 00:02:35 tons to the moon and Mars and eventually
00:02:35 --> 00:02:38 transporting hundreds of people. This
00:02:38 --> 00:02:40 successful suborbital mission is a
00:02:40 --> 00:02:43 monumental step demonstrating critical
00:02:43 --> 00:02:45 capabilities that pave the way for a future
00:02:46 --> 00:02:49 where space travel is routine and ambitious
00:02:49 --> 00:02:51 multi planetary missions become a reality.
00:02:52 --> 00:02:54 Especially with version three now on the
00:02:54 --> 00:02:55 horizon.
00:02:55 --> 00:02:58 Reason for orbital flights moving on to other
00:02:58 --> 00:03:00 spacefaring nations. China successfully
00:03:00 --> 00:03:03 launched a ah, long March 2D rocket carrying
00:03:03 --> 00:03:06 the Hayong 3 satellite into orbit.
00:03:06 --> 00:03:09 This mission marks another advancement in
00:03:09 --> 00:03:10 China's growing space capabilities,
00:03:11 --> 00:03:13 particularly in Earth observation.
00:03:14 --> 00:03:17 Avery: The Hayong 3 satellite is designed for marine
00:03:17 --> 00:03:19 environmental monitoring, which is incredibly
00:03:19 --> 00:03:21 important for understanding our oceans,
00:03:22 --> 00:03:25 climate and coastal regions. These satellites
00:03:25 --> 00:03:27 provide vital data for everything from
00:03:27 --> 00:03:29 disaster prediction to resource management.
00:03:29 --> 00:03:31 It's a testament to the continued global
00:03:31 --> 00:03:34 investment in space based observation
00:03:34 --> 00:03:34 systems.
00:03:34 --> 00:03:37 Anna: Indeed, Avery, these Haiyang satellites
00:03:37 --> 00:03:39 are crucial for global climate science.
00:03:40 --> 00:03:42 They provide continuous, high resolution
00:03:42 --> 00:03:45 data on sea surface temperature, ocean
00:03:45 --> 00:03:48 color, sea ice distribution, and ocean
00:03:48 --> 00:03:51 dynamics. This information is vital
00:03:51 --> 00:03:53 not only for understanding changes in our
00:03:53 --> 00:03:56 planet's climate and its impacts on marine
00:03:56 --> 00:03:59 ecosystems, but also for practical
00:03:59 --> 00:04:02 applications such as monitoring marine
00:04:02 --> 00:04:04 pollution, supporting sustainable fisheries,
00:04:05 --> 00:04:07 and aiding in maritime disaster response,
00:04:07 --> 00:04:10 including tracking oil spills and predicting
00:04:10 --> 00:04:13 harmful algal blooms. China's investment
00:04:13 --> 00:04:16 in this satellite series demonstrates a clear
00:04:16 --> 00:04:19 commitment to expanding its capabilities in
00:04:19 --> 00:04:22 Earth observation, positioning itself as a
00:04:22 --> 00:04:24 key player in international efforts to
00:04:24 --> 00:04:26 monitor and protect our planet.
00:04:26 --> 00:04:29 Avery: Now for something a little more celestial and
00:04:29 --> 00:04:32 less man made. The Northern Taurids meteor
00:04:32 --> 00:04:35 shower is now gracing our skies, peaking
00:04:35 --> 00:04:38 around November 12. Known for its
00:04:38 --> 00:04:41 bright fireballs, the Taurids are sometimes
00:04:41 --> 00:04:43 referred to as the Halloween Fireballs
00:04:43 --> 00:04:46 due to their early November appearance.
00:04:47 --> 00:04:49 Anna: They certainly are a spectacle. Avery the
00:04:49 --> 00:04:52 Taurids originate from debris left behind by
00:04:52 --> 00:04:55 Comet 2P enke. What makes them
00:04:55 --> 00:04:57 unique is that we pass through two streams of
00:04:57 --> 00:05:00 debris each year, the Southern Taurids in
00:05:00 --> 00:05:02 late October and the Northern Torrids in
00:05:02 --> 00:05:05 early November. This year, experts were
00:05:05 --> 00:05:08 predicting a potentially stronger showing
00:05:08 --> 00:05:10 with more bright meteors than usual, as
00:05:10 --> 00:05:13 Jupiter's gravity has perturbed the stream,
00:05:13 --> 00:05:16 bringing denser pockets of debris closer to
00:05:16 --> 00:05:17 Earth's orbit.
00:05:18 --> 00:05:20 Avery: Comet Tupianke is a fascinating
00:05:20 --> 00:05:23 object, a short period comet that
00:05:23 --> 00:05:26 completes an orbit around the sun in just
00:05:26 --> 00:05:29 3.3 years. This relatively
00:05:29 --> 00:05:32 frequent passage near the sun means it sheds
00:05:32 --> 00:05:34 a considerable amount of dust and debris,
00:05:35 --> 00:05:37 creating the two distinct streams that give
00:05:37 --> 00:05:40 us the Northern and Southern Taurids. What's
00:05:40 --> 00:05:43 particularly interesting is how Jupiter's
00:05:43 --> 00:05:46 immense gravitational pull can periodically
00:05:46 --> 00:05:49 sculpt and concentrate these debris streams,
00:05:49 --> 00:05:51 leading to years like this one where we might
00:05:51 --> 00:05:54 experience a higher frequency of brighter
00:05:54 --> 00:05:56 meteors or fireballs. These
00:05:56 --> 00:05:59 fireballs are essentially larger dust grains
00:05:59 --> 00:06:02 or small pebbles from the comet that burn up
00:06:02 --> 00:06:04 intensely as they enter Earth's atmosphere,
00:06:04 --> 00:06:07 creating a dazzling display for
00:06:07 --> 00:06:10 stargazers. Clear, dark skies away from city
00:06:10 --> 00:06:12 lights are always key, but
00:06:12 --> 00:06:15 understanding the radiant point in the
00:06:15 --> 00:06:17 constellation Taurus and checking for moon
00:06:17 --> 00:06:19 phase can also enhance the viewing
00:06:19 --> 00:06:22 experience. It's a beautiful reminder of the
00:06:22 --> 00:06:24 cosmic dust our planet constantly sweeps up
00:06:25 --> 00:06:28 as it journeys through space, shifting our
00:06:28 --> 00:06:28 gaze.
00:06:28 --> 00:06:30 Anna: Back to Historical Space Exploration
00:06:30 --> 00:06:33 NASA has opened pristine lunar samples from
00:06:33 --> 00:06:36 the Apollo 17 mission, which returned to
00:06:36 --> 00:06:39 Earth in 1972. These samples
00:06:39 --> 00:06:41 have been meticulously preserved in a vacuum
00:06:41 --> 00:06:44 seal for over 50 years, and scientists
00:06:44 --> 00:06:46 are now studying them with modern analytical
00:06:46 --> 00:06:47 techniques.
00:06:48 --> 00:06:51 Avery: This is a truly exciting development. These
00:06:51 --> 00:06:54 untouched samples offer an unparalleled
00:06:54 --> 00:06:57 opportunity to study the Moon's geology
00:06:57 --> 00:06:59 without any terrestrial contamination.
00:07:00 --> 00:07:02 Scientists are hoping to gain new insights
00:07:02 --> 00:07:05 into the Moon's formation, volcanic history,
00:07:05 --> 00:07:08 and the presence of volatile compounds, which
00:07:08 --> 00:07:10 could be crucial for future lunar missions
00:07:10 --> 00:07:13 and understanding the origins of water on the
00:07:13 --> 00:07:13 Moon.
00:07:14 --> 00:07:16 Anna: Scientists are particularly interested in the
00:07:16 --> 00:07:19 volatile compounds preserved within these
00:07:19 --> 00:07:22 vacuum sealed samples. Volatiles like water
00:07:22 --> 00:07:24 ice, trapped gases, and organic molecules
00:07:25 --> 00:07:27 can provide critical clues about the early
00:07:27 --> 00:07:30 solar system, including how water might have
00:07:30 --> 00:07:32 been delivered to both the Moon and Earth.
00:07:33 --> 00:07:35 The advanced analytical techniques available
00:07:35 --> 00:07:38 today, far more sophisticated than those of
00:07:38 --> 00:07:40 the Apollo era, allow for incredibly
00:07:40 --> 00:07:43 precise measurements of isotopic ratios and
00:07:43 --> 00:07:46 chemical compositions. This can help
00:07:46 --> 00:07:48 differentiate between different sources of
00:07:48 --> 00:07:50 lunar water, for example, distinguishing
00:07:50 --> 00:07:53 between cometary impacts and solar wind
00:07:53 --> 00:07:55 implantation. Furthermore,
00:07:56 --> 00:07:57 understanding the distribution and
00:07:57 --> 00:08:00 characteristics of these volatiles is
00:08:00 --> 00:08:02 paramount for future lunar habitats and
00:08:02 --> 00:08:05 resource utilization. If we can reliably
00:08:05 --> 00:08:07 extract water and other essential compounds
00:08:07 --> 00:08:10 from lunar soil, it dramatically reduces the
00:08:10 --> 00:08:13 cost and complexity of long duration
00:08:13 --> 00:08:15 missions, enabling a sustained human presence
00:08:15 --> 00:08:18 on the Moon and supporting deeper space
00:08:18 --> 00:08:18 exploration.
00:08:19 --> 00:08:22 And finally, as space exploration continues
00:08:22 --> 00:08:25 to accelerate, the issue of low Earth
00:08:25 --> 00:08:27 orbit, or leo, congestion is becoming
00:08:27 --> 00:08:30 increasingly critical. A recent study
00:08:30 --> 00:08:32 highlights the urgent need for international
00:08:32 --> 00:08:35 cooperation and sustainable practices to
00:08:35 --> 00:08:37 manage the ever growing number of satellites
00:08:37 --> 00:08:38 and debris in orbit.
00:08:39 --> 00:08:42 Avery: The study, conducted by a consortium
00:08:42 --> 00:08:44 of international space agencies and research
00:08:45 --> 00:08:47 institutions, underscores the
00:08:47 --> 00:08:50 escalating risk of collisions in leo.
00:08:50 --> 00:08:53 With thousands of active satellites and an
00:08:53 --> 00:08:56 ever increasing amount of space debris. The
00:08:56 --> 00:08:59 the potential for catastrophic cascade events
00:08:59 --> 00:09:02 known as the Kessler Syndrome, is a
00:09:02 --> 00:09:04 serious concern. Such events could
00:09:04 --> 00:09:07 render certain orbital altitudes unusable
00:09:07 --> 00:09:10 for decades, impacting vital services
00:09:10 --> 00:09:13 like gps, weather forecasting
00:09:13 --> 00:09:16 and global communication. The Kessler
00:09:16 --> 00:09:18 Syndrome is a particularly grim scenario
00:09:18 --> 00:09:21 where a single collision could trigger a
00:09:21 --> 00:09:24 chain reaction, creating so much debris
00:09:24 --> 00:09:27 that LEO becomes a perilous junkyard.
00:09:27 --> 00:09:30 Imagine losing access to satellite
00:09:30 --> 00:09:32 navigation, accurate weather predictions,
00:09:32 --> 00:09:35 and the very Internet connectivity that
00:09:35 --> 00:09:37 powers our modern world. It's not just
00:09:37 --> 00:09:40 about losing a few satellites. It's about
00:09:40 --> 00:09:43 jeopardizing the foundational infrastructure
00:09:43 --> 00:09:46 of our global society. This
00:09:46 --> 00:09:48 isn't a distant problem. The risks are
00:09:48 --> 00:09:51 increasing with every new satellite launch
00:09:51 --> 00:09:54 and every piece of debris generated.
00:09:54 --> 00:09:57 Urgent proactive measures are needed to
00:09:57 --> 00:10:00 prevent this cascading effect and preserve
00:10:00 --> 00:10:03 LEO as a vital resource for humanity.
00:10:04 --> 00:10:06 Addressing this critical issue requires a
00:10:06 --> 00:10:09 comprehensive multifaceted approach,
00:10:10 --> 00:10:12 encompassing stricter regulations on
00:10:12 --> 00:10:15 satellite launches, a universally
00:10:15 --> 00:10:17 adopted code of conduct for space operations
00:10:18 --> 00:10:20 and and significantly improve tracking of
00:10:20 --> 00:10:23 space debris, even down to centimeter
00:10:23 --> 00:10:26 sized fragments. Furthermore, the development
00:10:26 --> 00:10:29 and deployment of active debris removal
00:10:29 --> 00:10:31 technologies, which are still in their
00:10:31 --> 00:10:33 nascent stages, are becoming
00:10:33 --> 00:10:36 increasingly vital. International
00:10:36 --> 00:10:39 collaboration is not merely beneficial,
00:10:39 --> 00:10:41 it is absolutely paramount.
00:10:42 --> 00:10:44 Space is a shared global resource and
00:10:44 --> 00:10:47 the actions of any one nation or commercial
00:10:47 --> 00:10:50 entity can have far reaching consequences
00:10:50 --> 00:10:53 for all. Organizations like the United
00:10:53 --> 00:10:56 Nations Committee on the Peaceful Uses of
00:10:56 --> 00:10:58 Outer Space are actively working on
00:10:58 --> 00:11:01 establishing guidelines and best practices.
00:11:01 --> 00:11:04 But a, uh, more rapid implementation and
00:11:04 --> 00:11:07 robust enforcement mechanism across all
00:11:07 --> 00:11:10 spacefaring entities are urgently
00:11:10 --> 00:11:13 needed. Without concerted global effort,
00:11:13 --> 00:11:15 we risk creating a future where low Earth
00:11:15 --> 00:11:18 orbit becomes too hazardous, if not
00:11:18 --> 00:11:21 entirely unusable, for essential space
00:11:21 --> 00:11:23 operations that underpin much of our
00:11:23 --> 00:11:26 modern infrastructure and scientific
00:11:26 --> 00:11:26 advancement.
00:11:27 --> 00:11:29 Anna: The urgency of this situation cannot be
00:11:29 --> 00:11:32 overstated. Beyond the risk of direct
00:11:32 --> 00:11:34 collisions, there are concerns about light
00:11:34 --> 00:11:37 pollution from large satellite constellations
00:11:37 --> 00:11:39 interfering with astronomical observations,
00:11:40 --> 00:11:42 and even the potential for military implic
00:11:43 --> 00:11:45 if certain orbits become weaponized.
00:11:46 --> 00:11:48 Effective governance of outer space must
00:11:48 --> 00:11:51 evolve rapidly to keep pace with
00:11:51 --> 00:11:53 technological advancements. This includes
00:11:53 --> 00:11:55 developing clear legal frameworks for
00:11:55 --> 00:11:57 liability in the event of collisions,
00:11:58 --> 00:12:00 promoting data sharing on satellite positions
00:12:00 --> 00:12:03 and trajectories, and incentivizing private
00:12:03 --> 00:12:05 companies to adopt sustainable practices
00:12:06 --> 00:12:09 such as designing satellites for deorbiting
00:12:09 --> 00:12:10 at, uh, the end of their operational life.
00:12:11 --> 00:12:13 Without these collective efforts, the dream
00:12:13 --> 00:12:16 of a vibrant, accessible space economy could
00:12:16 --> 00:12:18 quickly turn into a nightmare of orbital
00:12:18 --> 00:12:21 debris, limiting humanity's reach beyond
00:12:21 --> 00:12:22 Earth for generations.
00:12:23 --> 00:12:25 Avery: The implications of unchecked LEO
00:12:25 --> 00:12:27 congestion are truly profound.
00:12:28 --> 00:12:30 Beyond the direct loss of satellite
00:12:30 --> 00:12:32 functionality, there is the long term
00:12:32 --> 00:12:35 environmental impact. Each collision
00:12:35 --> 00:12:37 creates thousands of new pieces of debris,
00:12:38 --> 00:12:40 exacerbating the problem and making future
00:12:40 --> 00:12:43 launches even riskier. This isn't just an
00:12:43 --> 00:12:45 inconvenience. It's a threat to our
00:12:45 --> 00:12:48 continued access to space, which has
00:12:48 --> 00:12:51 become indispensable for modern life,
00:12:51 --> 00:12:53 affecting everything from global commerce to
00:12:53 --> 00:12:55 disaster response.
00:12:55 --> 00:12:58 Anna: That's all for today's Astronomy Daily. We've
00:12:58 --> 00:13:00 covered a lot of ground, from the ambitious
00:13:00 --> 00:13:03 endeavors of SpaceX and their monumental
00:13:03 --> 00:13:06 Starship tests to China's significant
00:13:06 --> 00:13:08 advancements in Earth observation with the
00:13:08 --> 00:13:11 Hyong 3 satellite. We also
00:13:11 --> 00:13:13 delved into the dazzling spectacle of the
00:13:13 --> 00:13:16 northern torrid meteor shower, the
00:13:16 --> 00:13:18 invaluable scientific treasures unearthed
00:13:18 --> 00:13:21 from Apollo 17 lunar samples, and the
00:13:21 --> 00:13:24 critical ongoing need for managing low Earth
00:13:24 --> 00:13:27 orbit congestion. For the sustainability of
00:13:27 --> 00:13:30 our future in space, it's clear that the
00:13:30 --> 00:13:32 universe and our interaction with it
00:13:32 --> 00:13:34 continues to present both incredible
00:13:34 --> 00:13:37 opportunities and significant challenges,
00:13:38 --> 00:13:40 reminding us of the constant push for
00:13:40 --> 00:13:41 discovery and responsibility.
00:13:42 --> 00:13:45 Join us again tomorrow for more updates from
00:13:45 --> 00:13:48 the cosmos. Until then, keep looking up.
