00:00:00 --> 00:00:02 Hello and welcome to today's edition of
00:00:02 --> 00:00:04 Astronomy Daily, the podcast that brings
00:00:04 --> 00:00:07 you the universe one story at a time.
00:00:07 --> 00:00:08 I'm Avery
00:00:08 --> 00:00:11 >> and I'm Anna. It's great to be with you.
00:00:11 --> 00:00:13 Today we're covering some of the most
00:00:13 --> 00:00:15 exciting and slightly worrying news from
00:00:16 --> 00:00:18 the world of space exploration.
00:00:18 --> 00:00:19 >> Absolutely. We're going to be talking
00:00:20 --> 00:00:22 about a communications breakdown at
00:00:22 --> 00:00:25 Mars, a 2 million km tail trailing our
00:00:25 --> 00:00:27 own planet, and a brand new mission
00:00:27 --> 00:00:30 control center for future rovers.
00:00:30 --> 00:00:32 >> Plus, we'll dive into what the James Web
00:00:32 --> 00:00:33 telescope might have found on an
00:00:33 --> 00:00:36 exoplanet, a new dual mode drone from
00:00:36 --> 00:00:38 China, and a rocket fairing nicknamed
00:00:38 --> 00:00:40 the Hungry Hippo.
00:00:40 --> 00:00:42 >> It's a busy lineup, so let's get right
00:00:42 --> 00:00:45 into it. Anna, why don't you start us
00:00:45 --> 00:00:47 off with the news from the red planet?
00:00:47 --> 00:00:49 >> Of course. Our first story is a bit
00:00:49 --> 00:00:52 tense. NASA has temporarily, well, we
00:00:52 --> 00:00:54 hope it's temporary, lost contact with
00:00:54 --> 00:00:57 its Maven Orbiter. Maven, which stands
00:00:57 --> 00:00:59 for Mars Atmosphere and Volatile
00:00:59 --> 00:01:02 Evolution, has been a workhorse at Mars
00:01:02 --> 00:01:03 since 2014.
00:01:03 --> 00:01:05 >> Right. And it's not just studying the
00:01:05 --> 00:01:07 atmosphere. It's a critical
00:01:07 --> 00:01:09 communications relay for the rovers on
00:01:09 --> 00:01:11 the surface like Curiosity and
00:01:11 --> 00:01:14 Perseverance. Losing contact is a big
00:01:14 --> 00:01:15 deal.
00:01:15 --> 00:01:17 >> Exactly. The spacecraft went silent
00:01:17 --> 00:01:19 after passing behind Mars from our point
00:01:19 --> 00:01:22 of view, which is a standard procedure.
00:01:22 --> 00:01:23 But when it should have reemerged and
00:01:24 --> 00:01:26 checked in, there was nothing. The team
00:01:26 --> 00:01:28 at the Jet Propulsion Laboratory is now
00:01:28 --> 00:01:30 working through procedures to try and
00:01:30 --> 00:01:31 reestablish a signal.
00:01:31 --> 00:01:33 >> Mhm. So, what does this mean for the
00:01:33 --> 00:01:36 rovers? Are they on their own for now?
00:01:36 --> 00:01:39 >> Well, thankfully NASA has redundancy.
00:01:39 --> 00:01:41 The Mars Reconnaissance Orbiter and the
00:01:41 --> 00:01:44 European Space Ay's Trace Gas Orbiter
00:01:44 --> 00:01:46 can also act as relays, so the rovers
00:01:46 --> 00:01:48 aren't completely cut off. But losing
00:01:48 --> 00:01:50 Maven reduces their data downlink
00:01:50 --> 00:01:52 capacity significantly.
00:01:52 --> 00:01:54 >> That makes sense. Spacecraft issues like
00:01:54 --> 00:01:57 this happen, and usually the engineers
00:01:57 --> 00:01:59 find a way. We're certainly hoping they
00:01:59 --> 00:02:01 get Maven back online soon.
00:02:01 --> 00:02:03 >> Fingers crossed. Now for our next story,
00:02:03 --> 00:02:05 let's come a little closer to home.
00:02:05 --> 00:02:07 Avery, this one sounds like something
00:02:07 --> 00:02:09 out of science fiction.
00:02:09 --> 00:02:12 >> It really does. A new NASA study has
00:02:12 --> 00:02:15 confirmed that Earth has a tail. Not a
00:02:15 --> 00:02:17 physical one, of course, but a magnetic
00:02:17 --> 00:02:20 one. A magneto tail to be precise. That
00:02:20 --> 00:02:23 stretches an incredible 2 million km
00:02:23 --> 00:02:25 into space.
00:02:25 --> 00:02:27 >> 2 million km. That's more than five
00:02:27 --> 00:02:29 times the distance to the moon. How is
00:02:30 --> 00:02:32 that even formed? It's created by the
00:02:32 --> 00:02:34 interaction between Earth's magnetic
00:02:34 --> 00:02:36 field and the solar wind, which is a
00:02:36 --> 00:02:38 constant stream of charged particles
00:02:38 --> 00:02:41 flowing from the sun. As the solar wind
00:02:41 --> 00:02:43 blows past Earth, it stretches our
00:02:43 --> 00:02:45 magnetic field out on the night side,
00:02:46 --> 00:02:47 just like a wind sock.
00:02:47 --> 00:02:50 >> Right. And this tail isn't empty, is it?
00:02:50 --> 00:02:52 It's filled with plasma.
00:02:52 --> 00:02:55 >> Exactly. It's a plasma kale. and
00:02:55 --> 00:02:57 understanding its structure and dynamics
00:02:57 --> 00:02:59 is crucial for predicting space weather,
00:02:59 --> 00:03:01 which can affect our satellites and
00:03:01 --> 00:03:04 power grids. It's a stunning reminder of
00:03:04 --> 00:03:06 the complex invisible structures that
00:03:06 --> 00:03:09 dominate our corner of the cosmos.
00:03:09 --> 00:03:12 That's fascinating. From invisible tales
00:03:12 --> 00:03:14 to very visible new buildings, our next
00:03:14 --> 00:03:17 story takes us to NASA's Jet Propulsion
00:03:17 --> 00:03:19 Laboratory. They've just opened a new
00:03:19 --> 00:03:22 rover operation center, or ROC.
00:03:22 --> 00:03:24 >> Yeah, this is exciting. This isn't just
00:03:24 --> 00:03:27 a shiny new room with more computers.
00:03:27 --> 00:03:29 The ROC is designed to be the heart of
00:03:30 --> 00:03:32 future robotic missions to the moon and
00:03:32 --> 00:03:34 Mars. It's built to handle multiple
00:03:34 --> 00:03:36 missions simultaneously.
00:03:36 --> 00:03:38 >> And it incorporates some cutting edge
00:03:38 --> 00:03:41 technology, including advanced AI to
00:03:41 --> 00:03:43 help rover drivers plan their routes and
00:03:43 --> 00:03:45 analyze data more efficiently. They're
00:03:45 --> 00:03:47 also emphasizing partnerships with
00:03:47 --> 00:03:49 commercial space companies. That
00:03:49 --> 00:03:52 partnership piece is key. With programs
00:03:52 --> 00:03:54 like Artemis aiming to return humans to
00:03:54 --> 00:03:56 the moon and more ambitious Mars
00:03:56 --> 00:03:58 missions on the horizon, NASA needs a
00:03:58 --> 00:04:01 central hub that can coordinate between
00:04:01 --> 00:04:02 its own assets and those of its
00:04:02 --> 00:04:05 commercial partners. The ROC is that
00:04:05 --> 00:04:08 hub. It's basically mission control for
00:04:08 --> 00:04:11 the next generation of explorers.
00:04:11 --> 00:04:13 Speaking of next generation explorers,
00:04:13 --> 00:04:15 our next story comes from the James Webb
00:04:15 --> 00:04:17 Space Telescope, which is continuing to
00:04:17 --> 00:04:19 rewrite our understanding of distant
00:04:19 --> 00:04:20 worlds.
00:04:20 --> 00:04:23 >> I love a good JWST story. What has it
00:04:23 --> 00:04:24 spotted now?
00:04:24 --> 00:04:26 >> It's been looking at the Trappist 1
00:04:26 --> 00:04:28 system, which you'll remember as a
00:04:28 --> 00:04:30 system of seven rocky Earth-sized
00:04:30 --> 00:04:34 planets orbiting a small star. JWST
00:04:34 --> 00:04:37 focused on Trappist 1E, a planet in the
00:04:37 --> 00:04:39 habitable zone, and the data hints at
00:04:39 --> 00:04:41 the possibility of a methane rich
00:04:41 --> 00:04:42 atmosphere.
00:04:42 --> 00:04:45 >> Wow. Methane. On Earth, that's often
00:04:45 --> 00:04:47 associated with life, but the key word
00:04:47 --> 00:04:49 here is hints, right?
00:04:49 --> 00:04:52 >> Precisely. The data is still ambiguous.
00:04:52 --> 00:04:54 Scientists are quick to point out that
00:04:54 --> 00:04:56 methane can also be produced by
00:04:56 --> 00:04:58 geological processes, not just
00:04:58 --> 00:05:01 biological ones. The signal is also
00:05:01 --> 00:05:02 faint and could be an instrument
00:05:02 --> 00:05:05 artifact or something else entirely.
00:05:05 --> 00:05:07 >> So, it's not time to announce aliens
00:05:07 --> 00:05:08 just yet.
00:05:08 --> 00:05:11 >> Not just yet, but it is an incredibly
00:05:11 --> 00:05:14 tantalizing result. It shows that JWST
00:05:14 --> 00:05:16 is capable of detecting potential bio
00:05:16 --> 00:05:19 signatures on rocky exoplanets, which is
00:05:19 --> 00:05:21 exactly what it was designed to do. More
00:05:21 --> 00:05:23 observations are already planned to get
00:05:23 --> 00:05:25 a clearer picture.
00:05:25 --> 00:05:27 >> It's amazing to watch science unfold in
00:05:27 --> 00:05:30 real time. And while JWST looks out,
00:05:30 --> 00:05:32 other nations are looking at new ways to
00:05:32 --> 00:05:35 explore up close. Our fifth story is
00:05:35 --> 00:05:37 about a new type of Mars drone being
00:05:37 --> 00:05:39 developed in China.
00:05:39 --> 00:05:41 >> Mhm. We all remember the success of
00:05:41 --> 00:05:44 NASA's Ingenuity helicopter. This new
00:05:44 --> 00:05:46 concept takes that a step further.
00:05:46 --> 00:05:48 Chinese scientists are designing a drone
00:05:48 --> 00:05:50 that can both fly and roll on the
00:05:50 --> 00:05:51 Martian surface.
00:05:51 --> 00:05:54 >> Fly and roll. So, it's a transformer
00:05:54 --> 00:05:57 >> in a way. Yes. The idea is to conserve
00:05:57 --> 00:06:00 energy. Flying in Mars' thin atmosphere
00:06:00 --> 00:06:02 takes a lot of power. So, the drone
00:06:02 --> 00:06:04 would roll on its wheels for long
00:06:04 --> 00:06:06 distance travel across flat terrain and
00:06:06 --> 00:06:08 only use its rotors to fly over
00:06:08 --> 00:06:11 obstacles or explore hard-to-reach areas
00:06:11 --> 00:06:13 like canyons or cliffs.
00:06:13 --> 00:06:15 >> That's a very clever solution. It
00:06:15 --> 00:06:17 combines the endurance of a rover with
00:06:17 --> 00:06:19 the agility of a helicopter.
00:06:19 --> 00:06:21 >> It is. And the design could even allow
00:06:21 --> 00:06:23 it to enter and explore Martian lava
00:06:23 --> 00:06:26 tubes or caves, something no previous
00:06:26 --> 00:06:28 mission has been able to do. It's a
00:06:28 --> 00:06:30 concept that could dramatically expand
00:06:30 --> 00:06:32 our exploration capabilities on other
00:06:32 --> 00:06:33 worlds.
00:06:33 --> 00:06:35 >> That is a fascinating concept. It really
00:06:35 --> 00:06:37 shows how we're getting smarter about
00:06:37 --> 00:06:39 exploring other planets.
00:06:39 --> 00:06:41 >> It's certainly an exciting time in space
00:06:41 --> 00:06:42 innovation.
00:06:42 --> 00:06:44 >> All right, for our final story, let's
00:06:44 --> 00:06:46 talk about getting to space in the first
00:06:46 --> 00:06:48 place. This one involves Rocket Lab and
00:06:48 --> 00:06:51 a piece of hardware with a fantastic
00:06:51 --> 00:06:53 name, the hungry hippo fairing.
00:06:54 --> 00:06:56 >> I was waiting for this one. This is
00:06:56 --> 00:06:58 about their upcoming neutron rocket,
00:06:58 --> 00:07:00 which is designed to be fully reusable.
00:07:00 --> 00:07:02 The fairing is the nose cone that
00:07:02 --> 00:07:04 protects the satellite during launch.
00:07:04 --> 00:07:06 Typically, fairings are just jettisoned
00:07:06 --> 00:07:07 and fall into the ocean,
00:07:08 --> 00:07:10 >> right? Which is wasteful. SpaceX
00:07:10 --> 00:07:12 recovers theirs with nets on ships, but
00:07:12 --> 00:07:14 Rocket Lab has a totally different
00:07:14 --> 00:07:17 approach. The neutron's fairing isn't
00:07:17 --> 00:07:19 jettisoned at all. It's integrated into
00:07:19 --> 00:07:21 the first stage of the rocket.
00:07:21 --> 00:07:23 >> So, how does the satellite get out?
00:07:23 --> 00:07:25 >> This is the brilliant part. The fairing
00:07:25 --> 00:07:28 pedals open up like a giant clamshell or
00:07:28 --> 00:07:30 a hungry hungry hippo to release the
00:07:30 --> 00:07:33 payload. Then they close again before
00:07:33 --> 00:07:35 the entire first stage returns to Earth
00:07:35 --> 00:07:37 for a landing. Rocket Lab just completed
00:07:37 --> 00:07:40 successful tests of this mechanism.
00:07:40 --> 00:07:42 >> That's an elegant piece of engineering.
00:07:42 --> 00:07:44 It eliminates the entire process of
00:07:44 --> 00:07:46 fairing recovery at sea. It just comes
00:07:46 --> 00:07:48 back with the booster.
00:07:48 --> 00:07:50 >> It's a huge step towards rapid
00:07:50 --> 00:07:51 reusability, which is the key to
00:07:51 --> 00:07:54 lowering the cost of access to space. A
00:07:54 --> 00:07:56 very cool innovation to watch.
00:07:56 --> 00:07:58 >> And that's all the time we have for
00:07:58 --> 00:08:01 today's news roundup. From a silent
00:08:01 --> 00:08:03 orbiter at Mars to a hippo-like rocket
00:08:03 --> 00:08:06 here on Earth, it's been another busy
00:08:06 --> 00:08:07 time in space.
00:08:07 --> 00:08:10 >> It certainly has. Thank you all so much

00:08:20 --> 00:08:21 deep space.
