- Perseverance Rover's Potential Evidence of Life on Mars: NASA's Perseverance rover has uncovered what could be the strongest evidence yet for microbial life on Mars. The discovery of "leopard spots" on a rock in the Bright Jingle Formation contains organic carbon-rich material, clay minerals, and iron sulfide minerals that suggest biological processes akin to those of Earth microbes. While skepticism remains, the analysis indicates that these findings are most likely biological in origin, pending further examination through the Mars Sample Return mission.
- Risks of Asteroid Deflection Missions: A new study reveals that asteroid deflection missions might inadvertently increase the risk of Earth impacts. Researchers found that improper deflection could steer asteroids into gravitational keyholes, leading them onto collision courses with Earth. Sophisticated planning and probability maps are essential for safely redirecting asteroids, highlighting the complexity of such missions.
- James Webb Telescope's Massive Stellar Jet Discovery: The James Webb Space Telescope has captured astonishing images of an eight-light-year-long stellar jet originating from a massive protostar in the Sharpless 2284 Nebula. This discovery provides insights into the formation of massive stars and the dynamics of stellar jets, which scale with stellar mass.
- Pentagon's New Missile Defense Satellites: The Pentagon has launched 21 satellites for a new missile defense constellation, part of a plan to deploy 154 satellites in low Earth orbit. This innovative approach reduces costs significantly and enhances capabilities to detect modern threats like hypersonic weapons, marking a shift in military satellite economics.
- Nasa's Creative Helicopter Training: NASA has introduced a helicopter flight training course in the Colorado mountains to simulate lunar landing conditions for the Artemis missions. This hands-on training focuses on crew coordination and communication, preparing astronauts for the challenges of landing on the Moon amidst difficult terrain and lunar dust.
- Gaia Mission's Stellar Discoveries: The European Space Agency's Gaia mission has revealed complex star formation processes, identifying massive stellar streams in our galaxy. This groundbreaking data challenges previous notions of star formation, showing that it occurs in interconnected cascades triggered by supernovae, providing a deeper understanding of our galactic history.
- Artemis Gateway Updates: NASA has shared new details about the Gateway Lunar Space Station, which will serve as a hub for lunar missions and potentially a refueling stop for Mars expeditions. This initiative emphasizes international cooperation and in situ resource utilization, paving the way for humanity's expansion into the solar system.

00:00:00 --> 00:00:03 Anna: Welcome to Astronomy Daily. Your
00:00:03 --> 00:00:06 go to source for the latest discoveries and
00:00:06 --> 00:00:08 developments in space science. I'm
00:00:08 --> 00:00:11 Anna, and joining me as always, is my
00:00:11 --> 00:00:14 co host, Avery. Today we've got some
00:00:14 --> 00:00:17 absolutely fascinating stories to share with
00:00:17 --> 00:00:17 you.
00:00:17 --> 00:00:20 Avery: Hey everyone. Avery here and Anna. Uh,
00:00:20 --> 00:00:22 you're not kidding about fascinating. We're
00:00:22 --> 00:00:24 talking about what might be the best evidence
00:00:24 --> 00:00:27 yet for life on Mars. Some surprising risks
00:00:27 --> 00:00:30 with asteroid deflection missions. And NASA
00:00:30 --> 00:00:32 is getting creative with helicopter training
00:00:32 --> 00:00:35 in the mountains. Plus, the Pentagon just
00:00:35 --> 00:00:36 launched a bunch of satellites that could
00:00:36 --> 00:00:38 change missile defense forever.
00:00:38 --> 00:00:41 Anna: Right. It's like science fiction becoming
00:00:41 --> 00:00:44 science fact. Let's dive right into
00:00:44 --> 00:00:45 our biggest story today.
00:00:45 --> 00:00:48 The Perseverance rover has been busy on Mars,
00:00:48 --> 00:00:51 and the data it's sending back is absolutely
00:00:51 --> 00:00:54 mind blowing. We might be looking at the
00:00:54 --> 00:00:57 strongest evidence yet for microbial life on
00:00:57 --> 00:00:58 the red planet.
00:00:58 --> 00:01:00 Avery: Okay, so tell me about these leopard spots,
00:01:00 --> 00:01:01 Anna, because when I first heard about this
00:01:01 --> 00:01:03 story, I thought someone was pulling my leg.
00:01:03 --> 00:01:05 Leopard spots on Mars?
00:01:05 --> 00:01:08 Anna: I know it sounds wild, but that's exactly
00:01:08 --> 00:01:11 what scientists are calling these speckled
00:01:11 --> 00:01:14 patterns on a rock called Shevia Falls
00:01:14 --> 00:01:16 in the Bright Angel Formation. And here's
00:01:16 --> 00:01:18 where it gets really interesting. These
00:01:18 --> 00:01:21 aren't just pretty patterns. The spots
00:01:21 --> 00:01:24 contain organic carbon rich material,
00:01:24 --> 00:01:27 which is already exciting. But there's so
00:01:27 --> 00:01:27 much more.
00:01:28 --> 00:01:30 Avery: More? Lay it on me. What else did
00:01:30 --> 00:01:31 Perseverance find in these spots?
00:01:31 --> 00:01:34 Anna: Well, they found clay minerals, which tells
00:01:34 --> 00:01:37 us water was definitely present when this
00:01:37 --> 00:01:39 rock formed. Then there's calcium
00:01:39 --> 00:01:42 sulfate, iron phosphate, and here's the
00:01:42 --> 00:01:45 kicker. Iron sulfide minerals,
00:01:45 --> 00:01:48 probably vivianite and grigite. These
00:01:48 --> 00:01:50 specific minerals are really important
00:01:50 --> 00:01:53 because they suggest biological processes
00:01:53 --> 00:01:56 similar to what we see with Earth microbes
00:01:56 --> 00:01:59 that literally breathe rust and sulfate.
00:01:59 --> 00:02:02 Avery: Wait, microbes that breathe rust? That sounds
00:02:02 --> 00:02:04 like something out of a superhero movie. How
00:02:04 --> 00:02:05 does that even work?
00:02:05 --> 00:02:07 Anna: It's actually pretty amazing. These
00:02:07 --> 00:02:10 microbes use iron and sulfate
00:02:10 --> 00:02:12 compounds instead of oxygen for their
00:02:12 --> 00:02:15 metabolism. They basically heat eat the rust
00:02:15 --> 00:02:18 and sulfate to survive. And the mineral
00:02:18 --> 00:02:20 signatures we're seeing on Mars are exactly
00:02:20 --> 00:02:23 what you'd expect to find as waste products
00:02:23 --> 00:02:25 from this kind of biological activity.
00:02:26 --> 00:02:28 Avery: Okay, but I have to ask the skeptical
00:02:28 --> 00:02:30 question here. Could there be non biological
00:02:30 --> 00:02:33 explanations for these patterns and minerals?
00:02:33 --> 00:02:36 Anna: That's exactly the right question to ask. And
00:02:36 --> 00:02:38 scientists have considered that non
00:02:38 --> 00:02:41 biological processes could theoretically
00:02:41 --> 00:02:44 create these minerals, but they would require
00:02:44 --> 00:02:46 extreme conditions. We're talking
00:02:47 --> 00:02:49 temperatures between 150 and 200
00:02:49 --> 00:02:52 degrees Celsius, or extremely high
00:02:52 --> 00:02:55 acidity. The problem is, when
00:02:55 --> 00:02:57 researchers analyzed the rocks, they found
00:02:57 --> 00:03:00 no evidence of these extreme conditions
00:03:00 --> 00:03:01 ever being present.
00:03:02 --> 00:03:04 Avery: So we're left with biology as the most likely
00:03:04 --> 00:03:07 explanation. But we're not popping champagne
00:03:07 --> 00:03:08 just yet. Right? What's the next step
00:03:09 --> 00:03:09 exactly?
00:03:09 --> 00:03:12 Anna: The samples need to be returned to Earth for
00:03:12 --> 00:03:15 definitive analysis. We need the full
00:03:15 --> 00:03:17 power of Earth based laboratories to really
00:03:17 --> 00:03:20 confirm what seeing. That's where missions
00:03:20 --> 00:03:23 like Mars Sample Return become absolutely
00:03:23 --> 00:03:26 crucial. We're potentially looking at one of
00:03:26 --> 00:03:29 the most significant scientific discoveries
00:03:29 --> 00:03:31 in human history, but we need those
00:03:31 --> 00:03:33 samples back home to be sure.
00:03:33 --> 00:03:35 Avery: Speaking of things that could go wrong, our
00:03:35 --> 00:03:38 next story is a real eye opener about
00:03:38 --> 00:03:40 asteroid deflection missions. Turns out
00:03:40 --> 00:03:42 trying to save Earth from an asteroid impact
00:03:42 --> 00:03:45 might accidentally put us in more danger if
00:03:45 --> 00:03:46 we're not extremely careful.
00:03:47 --> 00:03:50 Anna: This story really got my attention because it
00:03:50 --> 00:03:52 sounds counterintuitive. How can
00:03:52 --> 00:03:55 protecting Earth from an asteroid make things
00:03:55 --> 00:03:55 worse?
00:03:56 --> 00:03:58 Avery: It all comes down to something called
00:03:58 --> 00:04:00 gravitational keyholes. These are
00:04:00 --> 00:04:03 specific areas in space where a planet's
00:04:03 --> 00:04:05 gravity can alter an asteroid's trajectory
00:04:06 --> 00:04:08 in unexpected ways. Researcher Raheel
00:04:08 --> 00:04:11 Makadia and his team, building on results
00:04:11 --> 00:04:14 from the DART mission, discovered that if you
00:04:14 --> 00:04:16 hit an asteroid in the wrong spot or at the
00:04:16 --> 00:04:19 wrong angle, you could accidentally steer it
00:04:19 --> 00:04:21 through one of these keyholes.
00:04:21 --> 00:04:23 Anna: And then the planet's gravity takes over and
00:04:23 --> 00:04:26 potentially sends the asteroid on a collision
00:04:26 --> 00:04:28 course with Earth. That's terrifying. How do
00:04:28 --> 00:04:29 we avoid this?
00:04:30 --> 00:04:32 Avery: The solution is really sophisticated
00:04:32 --> 00:04:35 planning. Makadia's team has created what
00:04:35 --> 00:04:37 they call probability maps that show where
00:04:37 --> 00:04:40 asteroids are most likely to go after being
00:04:40 --> 00:04:42 deflected. They have to consider everything.
00:04:43 --> 00:04:46 The asteroid's shape, how fast it's rotating,
00:04:46 --> 00:04:48 its mass, even the topology of its surface.
00:04:49 --> 00:04:51 Every asteroid is different, so each one
00:04:51 --> 00:04:54 requires its own detailed analysis to
00:04:54 --> 00:04:56 find the safest impact zones.
00:04:56 --> 00:04:59 Anna: It's like cosmic billiards, but with the
00:04:59 --> 00:05:02 fate of humanity hanging in the balance. This
00:05:02 --> 00:05:04 research really shows how complex space
00:05:04 --> 00:05:06 missions can be. You can't just point a
00:05:06 --> 00:05:08 spacecraft at an asteroid and hope for the
00:05:08 --> 00:05:09 best.
00:05:09 --> 00:05:11 Avery: Exactly. And it makes the DART mission
00:05:11 --> 00:05:14 results even more valuable because now we
00:05:14 --> 00:05:17 have real world data about how these impacts
00:05:17 --> 00:05:17 actually work.
00:05:18 --> 00:05:20 Speaking of impressive space discoveries,
00:05:21 --> 00:05:23 let's talk about what the Webb Telescope has
00:05:23 --> 00:05:26 been up to lately. Anna. Uh, this stellar jet
00:05:26 --> 00:05:27 story is pretty incredible.
00:05:28 --> 00:05:30 Anna: Oh, wow. Yes. Webb captured images of
00:05:30 --> 00:05:33 this absolutely massive stellar jet and
00:05:33 --> 00:05:36 the Sharpless 2284 Nebula.
00:05:36 --> 00:05:38 We're talking about a jet that's eight light
00:05:38 --> 00:05:40 years long. To put that in perspective,
00:05:40 --> 00:05:43 that's almost twice the distance from our sun
00:05:43 --> 00:05:45 to the nearest star, Proxima Centauri.
00:05:45 --> 00:05:47 Avery: Eight light years long, that's mind boggling.
00:05:47 --> 00:05:50 What's creating this massive jet.
00:05:50 --> 00:05:52 Anna: It's streaming from a protostar, basically a
00:05:52 --> 00:05:55 baby star that's still forming. And this
00:05:55 --> 00:05:57 particular protostar weighs about 10 times
00:05:57 --> 00:06:00 more than our sun. The whole system is
00:06:00 --> 00:06:02 located about 15 light years away from
00:06:02 --> 00:06:05 us. What makes this discovery so special is
00:06:05 --> 00:06:07 that most protostellar jets we've observed
00:06:07 --> 00:06:10 before came from much smaller, low mass
00:06:10 --> 00:06:10 stars.
00:06:11 --> 00:06:13 Avery: So this is giving us insights into how
00:06:13 --> 00:06:15 massive stars form, which is still pretty
00:06:15 --> 00:06:16 mysterious, right?
00:06:16 --> 00:06:19 Anna: Absolutely. And there's another fascinating
00:06:19 --> 00:06:22 aspect. This discovery provides evidence
00:06:22 --> 00:06:24 that jets scale with stellar mass.
00:06:24 --> 00:06:27 Bigger star, bigger jet. Plus it's giving us
00:06:27 --> 00:06:29 insights into massive star formation and low
00:06:29 --> 00:06:32 metallicity environments, which are similar
00:06:32 --> 00:06:34 to conditions in the early universe. It's
00:06:34 --> 00:06:36 like getting a window into how the first
00:06:36 --> 00:06:39 massive stars formed billions of years ago.
00:06:40 --> 00:06:43 Avery: From massive stars to missile defense.
00:06:43 --> 00:06:45 Our next story takes us back down to Earth.
00:06:45 --> 00:06:48 Well, sort of. The Pentagon just launched
00:06:48 --> 00:06:50 21 satellites as part of a new missile
00:06:50 --> 00:06:53 defense constellation. Anna, uh, this sounds
00:06:53 --> 00:06:55 like something out of a Tom Clancy novel.
00:06:55 --> 00:06:57 Anna: It really does. They're calling it the
00:06:57 --> 00:07:00 proliferated Warfighter Space architecture.
00:07:00 --> 00:07:02 And these 21 satellites are just the
00:07:02 --> 00:07:05 beginning. The plan is to build 154
00:07:05 --> 00:07:08 operational satellites over the next nine
00:07:08 --> 00:07:10 months. But here's what's really interesting.
00:07:10 --> 00:07:13 They're completely changing the economics of
00:07:13 --> 00:07:14 military satellite.
00:07:14 --> 00:07:17 Avery: How so? I imagine military satellites are
00:07:17 --> 00:07:17 pretty expensive.
00:07:18 --> 00:07:20 Anna: Traditional military satellites in
00:07:20 --> 00:07:22 geosynchronous orbit cost over a billion
00:07:22 --> 00:07:25 dollars each. These new ones, 14
00:07:25 --> 00:07:28 to 15 million each. That's a massive cost
00:07:28 --> 00:07:31 reduction. They're operating in low Earth
00:07:31 --> 00:07:32 orbit instead of the much higher
00:07:32 --> 00:07:34 geosynchronous orbits. And they're designed
00:07:34 --> 00:07:37 to work as a network rather than individual
00:07:37 --> 00:07:38 super expensive satellites.
00:07:39 --> 00:07:42 Avery: So it's quantity over individual capability.
00:07:42 --> 00:07:44 What will these satellites actually do?
00:07:44 --> 00:07:46 Anna: They'll provide beyond line of sight
00:07:46 --> 00:07:49 communications using Link 16 tactical data
00:07:49 --> 00:07:51 networks, which is military communications
00:07:51 --> 00:07:53 standard. But more importantly, they're
00:07:53 --> 00:07:55 designed to detect modern threats like
00:07:55 --> 00:07:58 hypersonic weapons, which are notoriously
00:07:58 --> 00:08:00 difficult to track with traditional systems
00:08:00 --> 00:08:02 because of their speed and unpredictable
00:08:02 --> 00:08:03 flight packs.
00:08:03 --> 00:08:05 Avery: That makes sense. Having a distributed
00:08:05 --> 00:08:08 network of cheaper satellites means you're
00:08:08 --> 00:08:09 less vulnerable if you lose one or two.
00:08:10 --> 00:08:12 And finally, let's talk about NASA getting
00:08:12 --> 00:08:15 creative with astronaut training. Are they
00:08:15 --> 00:08:17 using helicopters in the Colorado mountains?
00:08:18 --> 00:08:20 Anna: This is such a clever training approach.
00:08:21 --> 00:08:24 NASA just certified a new helicopter flight
00:08:24 --> 00:08:26 training course in the Colorado mountains
00:08:26 --> 00:08:28 specifically designed to simulate lunar
00:08:28 --> 00:08:31 landing conditions for the Artemis missions.
00:08:31 --> 00:08:34 Astronauts Mark Vande Hei and Matthew Dominic
00:08:34 --> 00:08:36 were part of the certification process.
00:08:36 --> 00:08:39 Avery: I'm trying to picture this. How do mountains
00:08:39 --> 00:08:41 in Colorado simulate the moon?
00:08:42 --> 00:08:45 Anna: Great question. The mountainous terrain
00:08:45 --> 00:08:47 Creates similar visual allusions
00:08:48 --> 00:08:50 to what astronauts will experience when
00:08:50 --> 00:08:52 landing on the Moon. Without familiar
00:08:52 --> 00:08:54 reference points, it becomes really
00:08:54 --> 00:08:56 challenging to judge distances and
00:08:56 --> 00:08:59 altitudes accurately. Plus, the
00:08:59 --> 00:09:02 dusty conditions in some areas help
00:09:02 --> 00:09:04 simulate how lunar dust will interact
00:09:04 --> 00:09:07 with the lander's thrusters. Which is
00:09:07 --> 00:09:09 actually a major concern for lunar missions.
00:09:10 --> 00:09:13 Avery: Right, because lunar dust is extremely fine
00:09:13 --> 00:09:15 and gets kicked up by the rocket exhaust,
00:09:15 --> 00:09:17 which can create a total whiteout during
00:09:17 --> 00:09:20 landing. This real world flight training
00:09:20 --> 00:09:22 sounds way better than just using simulators.
00:09:22 --> 00:09:25 Anna: Exactly. And it's not just about individual
00:09:25 --> 00:09:28 piloting skills. The training focuses heavily
00:09:28 --> 00:09:30 on crew coordination and communication,
00:09:31 --> 00:09:33 which will be absolutely critical when
00:09:33 --> 00:09:35 they're trying to land on the moon. There's
00:09:35 --> 00:09:37 no room for miscommunication when you're
00:09:37 --> 00:09:39 piloting a lunar lander to the surface.
00:09:40 --> 00:09:42 Avery: It's amazing how NASA keeps finding
00:09:42 --> 00:09:44 innovative ways to prepare for these
00:09:44 --> 00:09:46 missions. From potential life on Mars to
00:09:46 --> 00:09:49 asteroid deflection challenges, from massive
00:09:49 --> 00:09:52 stellar jets to military satellites and lunar
00:09:52 --> 00:09:54 landing training. What a week for space news.
00:09:55 --> 00:09:57 Anna: It really has been incredible. And I think
00:09:57 --> 00:10:00 what strikes me most is how all these stories
00:10:00 --> 00:10:02 show us that space exploration is this
00:10:02 --> 00:10:05 perfect blend of cutting edge science,
00:10:05 --> 00:10:08 careful planning, and sometimes creative
00:10:08 --> 00:10:10 problem solving. Whether we're looking for
00:10:10 --> 00:10:12 life on Mars or training astronauts in
00:10:12 --> 00:10:15 Colorado mountains, it's all about pushing
00:10:15 --> 00:10:16 the boundaries of what's possible.
00:10:17 --> 00:10:19 Avery: Couldn't agree more, Ana. Um, that's all for
00:10:19 --> 00:10:22 today's episode of Astronomy Daily. Thanks
00:10:22 --> 00:10:23 for joining us on this journey through the
00:10:23 --> 00:10:25 latest space discoveries and developments.
00:10:26 --> 00:10:28 Anna: Keep looking up, everyone. The universe has
00:10:28 --> 00:10:31 so much more to show us. Until next time,
00:10:31 --> 00:10:33 this is Ana and Avery signing off from
00:10:33 --> 00:10:34 Astronomy Daily.
00:10:34 --> 00:10:37 Avery: Actually, Ana, before we wrap up, I wanted to
00:10:37 --> 00:10:40 touch on one more fascinating story that came
00:10:40 --> 00:10:41 across our desk this week.
00:10:41 --> 00:10:44 The European Space Agency just announced some
00:10:44 --> 00:10:46 remarkable findings from their Gaia mission
00:10:46 --> 00:10:49 about stellar merceries in our galaxy. It's
00:10:49 --> 00:10:50 really changing how we understand star
00:10:50 --> 00:10:51 formation.
00:10:51 --> 00:10:54 Anna: Oh, yes, the Gaia data is
00:10:54 --> 00:10:56 incredible. They've been mapping the
00:10:56 --> 00:10:58 positions and movements of over a billion
00:10:58 --> 00:11:01 stars. And what they're finding about stellar
00:11:01 --> 00:11:04 associations and how stars form and clusters
00:11:04 --> 00:11:07 is really rewriting the textbooks. Tell
00:11:07 --> 00:11:09 our listeners what makes this discovery so
00:11:09 --> 00:11:09 special.
00:11:10 --> 00:11:13 Avery: So what Gaia has revealed is that, uh, star
00:11:13 --> 00:11:14 formation is much more complex and
00:11:14 --> 00:11:16 interconnective than we previously thought.
00:11:17 --> 00:11:19 They've identified these massive stellar
00:11:19 --> 00:11:22 streams, Groups of stars that were born
00:11:22 --> 00:11:24 together and are still moving through space
00:11:24 --> 00:11:26 together even millions of years after their
00:11:26 --> 00:11:29 formation. Some of these streams stretch for
00:11:29 --> 00:11:31 hundreds of light years across our galaxy.
00:11:32 --> 00:11:34 Anna: That's mind blowing when you think about it.
00:11:34 --> 00:11:36 Our sun could have siblings scattered across
00:11:36 --> 00:11:38 the galaxy that we're just now discovering.
00:11:39 --> 00:11:41 But what does this tell us about how star
00:11:41 --> 00:11:44 formation actually works? I mean, this seems
00:11:44 --> 00:11:46 to challenge the idea that stars just form
00:11:47 --> 00:11:48 randomly throughout.
00:11:50 --> 00:11:52 Avery: Exactly. It's showing us that star formation
00:11:52 --> 00:11:55 happens in these cascade events. When one
00:11:55 --> 00:11:58 massive star explodes as a supernova, it
00:11:58 --> 00:12:00 triggers star formation in nearby gas clouds,
00:12:00 --> 00:12:03 which can then trigger more star formation
00:12:03 --> 00:12:05 and so on. It's like cosmic dominoes.
00:12:05 --> 00:12:08 And here's the really cool. By tracing these
00:12:08 --> 00:12:11 stellar streams backward in time, astronomers
00:12:11 --> 00:12:13 can actually map out the history of star
00:12:13 --> 00:12:16 formation in different regions of our galaxy.
00:12:16 --> 00:12:18 Anna: It's like having a time machine for galactic
00:12:18 --> 00:12:21 archaeology. And this connects beautifully to
00:12:21 --> 00:12:23 our earlier discussion about that massive
00:12:23 --> 00:12:26 stellar jet Webb observed. We're seeing the
00:12:26 --> 00:12:28 universe as this incredibly interconnected
00:12:28 --> 00:12:31 system where everything influences everything
00:12:31 --> 00:12:34 else across vast distances and
00:12:34 --> 00:12:35 timescales.
00:12:35 --> 00:12:37 Avery: Speaking of interconnected systems, Anna, I,
00:12:37 --> 00:12:40 uh, also wanted to mention the latest updates
00:12:40 --> 00:12:42 from the Artemis program. NASA just released
00:12:42 --> 00:12:45 some new details about the gateway Lunar
00:12:45 --> 00:12:47 Space Station and how it's going to serve as
00:12:47 --> 00:12:50 a st point not just for moon missions, but
00:12:50 --> 00:12:52 potentially as a refueling stop for missions
00:12:52 --> 00:12:55 to Mars. The engineering behind this is
00:12:55 --> 00:12:56 absolutely fascinating.
00:12:57 --> 00:13:00 Anna: Yes, the gateway concept is brilliant because
00:13:00 --> 00:13:02 it's essentially creating a permanent human
00:13:02 --> 00:13:05 presence in lunar orbit. What's really
00:13:05 --> 00:13:07 exciting is how they're planning to use in
00:13:07 --> 00:13:10 situ resource utilization, basically
00:13:10 --> 00:13:12 mining water ice from the moon's south pole
00:13:13 --> 00:13:15 to create rocket fuel. And this could make
00:13:15 --> 00:13:17 Mars missions exponentially more cost
00:13:17 --> 00:13:19 effective because you wouldn't have to carry
00:13:19 --> 00:13:21 all your fuel from m Earth.
00:13:21 --> 00:13:23 Avery: Right. Because escaping Earth's gravity well
00:13:23 --> 00:13:26 is so energy intensive. If you can refuel at
00:13:26 --> 00:13:28 the moon, you're essentially getting a head
00:13:28 --> 00:13:30 start toward Mars. And the international
00:13:30 --> 00:13:33 cooperation aspect is really encouraging too.
00:13:33 --> 00:13:36 We've got contributions from Canada, Europe,
00:13:36 --> 00:13:39 Japan and other partners. It feels like we're
00:13:39 --> 00:13:41 building the infrastructure for humanity's
00:13:41 --> 00:13:42 expansion into the solar system.
00:13:43 --> 00:13:46 Anna: And speaking of international cooperation, I
00:13:46 --> 00:13:48 have to mention the incredible success we're
00:13:48 --> 00:13:51 seeing with commercial space companies. Just
00:13:51 --> 00:13:53 this month, SpaceX conducted their most
00:13:53 --> 00:13:56 ambitious starship test yet. And we're
00:13:56 --> 00:13:58 seeing companies like Blue Origin and others
00:13:59 --> 00:14:01 really pushing the boundaries of what's
00:14:01 --> 00:14:03 possible. The cost of getting to space
00:14:03 --> 00:14:06 continues to plummet, which opens up so many
00:14:06 --> 00:14:08 possibilities for scientific research.
00:14:09 --> 00:14:11 Avery: Anna, uh, what an incredible journey we've
00:14:11 --> 00:14:13 taken our listeners on today. From the
00:14:13 --> 00:14:15 potential discovery of ancient life on Mars
00:14:15 --> 00:14:17 to the cutting edge engineering that's making
00:14:17 --> 00:14:20 space more accessible than ever before. It
00:14:20 --> 00:14:23 really shows how rapidly our understanding of
00:14:23 --> 00:14:24 the universe is expanding.
00:14:24 --> 00:14:27 Anna: Absolutely, Avery. And I think what's most
00:14:27 --> 00:14:30 exciting is that we're not just passive
00:14:30 --> 00:14:32 observers anymore. We're actively
00:14:32 --> 00:14:35 participating in this exploration. Whether
00:14:35 --> 00:14:37 through robotic missions, human spaceflight,
00:14:37 --> 00:14:39 or the incredible engineering achievements
00:14:39 --> 00:14:42 that are making it all possible, the future
00:14:42 --> 00:14:44 of space exploration has never looked
00:14:44 --> 00:14:45 brighter.
00:14:45 --> 00:14:47 Avery: Well said, Anna. Uh, that's a wrap for
00:14:47 --> 00:14:50 today's extended episode of Astronomy Daily.
00:14:50 --> 00:14:52 Thanks for joining us on this comprehensive
00:14:52 --> 00:14:54 look at the latest in space science and
00:14:54 --> 00:14:56 exploration. Until next time, keep looking
00:14:56 --> 00:14:57 up.
