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

00:08:15 --> 00:08:17 time as we take a dive into more mysteries
00:08:17 --> 00:08:18 from deep space.
00:08:19 --> 00:08:21 Anna: Until then, keep looking up.
