Latest / Space News Today / Rocket Lab’s Hungry Hippos Arrive!| NASA Enlists Global Volunteers for Artemis II
Transcript
- 0:00Welcome to Astronomy Daily, your source
- 0:03for the latest space and astronomy news.
- 0:06I'm Anna.
- 0:07>> And I'm Avery. Thanks for joining us on
- 0:09this Saturday, January 24th, 2026.
- 0:13We've got some fantastic stories lined
- 0:16up for you today.
- 0:17>> We certainly do. From rocket development
- 0:20milestones to prehistoric lunar
- 0:22discoveries, today's episode is packed
- 0:25with celestial intrigue. Let's dive
- 0:28right in with our top story. Rocket
- 0:31Lab's ambitious Neutron rocket has hit a
- 0:34significant milestone even though it
- 0:36came with a bit of a bump in the road.
- 0:38Anna, what's the latest from Wallops
- 0:40Island? Well, Avery, it's a story of
- 0:43both triumph and setback. The good news
- 0:46first, Rocket Lab's innovative hungry
- 0:49hippo fairings have successfully arrived
- 0:52at Wallops Island, Virginia after a
- 0:54month-long sea journey from New Zealand.
- 0:57aboard the vessel Northstar Integrity.
- 1:00These aren't your typical payload
- 1:02fairings. They're part of Neutron's
- 1:04groundbreaking reusable system.
- 1:07>> Right. And what makes these hungry
- 1:09hippos so special?
- 1:11>> Great question. Unlike traditional
- 1:13fairings that are jettisoned and lost
- 1:15during flight, these clamshellike
- 1:18structures actually stay attached to the
- 1:20first stage as it returns home. They
- 1:23open to release the second stage and
- 1:26payload, then close back up for the ride
- 1:28home. It's a clever design that should
- 1:31help drive down launch costs through
- 1:33rapid reuse.
- 1:34>> That's fascinating engineering, but you
- 1:37mentioned a setback.
- 1:38>> Unfortunately, yes. While the fairings
- 1:41were making their journey, Rocket Lab
- 1:44experienced a tank rupture during
- 1:46qualification trials at their Middle
- 1:48River, Maryland facility. A first stage
- 1:51carbon composite tank failed during
- 1:54hydrostatic pressure testing. That's
- 1:56where they fill the structure with water
- 1:58and gradually increase pressure to
- 2:01verify it can handle operational loads.
- 2:04>> Ouch. How significant is that?
- 2:06>> Well, Rocket Lab was quick to emphasize
- 2:09that testing failures like this, while
- 2:12disappointing, are actually part of the
- 2:14rigorous development process for high
- 2:16performance rockets. They deliberately
- 2:19stress hardware to its limits and beyond
- 2:22to ensure reliability. The tank was
- 2:24found collapsed into a pile of debris.
- 2:27But the company maintains this is
- 2:29exactly why they test to find these
- 2:32issues on the ground rather than during
- 2:34flight.
- 2:35>> Silver lining thinking and the program
- 2:38moves forward.
- 2:39>> Absolutely. With the hungry hippo
- 2:41fairings now at Wallops, engineers can
- 2:44proceed with integration testing, fit
- 2:47checks, electrical interfaces, and
- 2:49eventually static fire preparations. The
- 2:52launch mount is already in place with
- 2:54the test stand ready for major testing
- 2:57with the rocket's second stage.
- 2:59>> Exciting times for commercial space
- 3:01flight. Now, speaking of major missions,
- 3:04NASA has some news about tracking the
- 3:06upcoming Artemis 2 mission, right?
- 3:08>> They do indeed. NASA has selected 34
- 3:12global volunteers from 14 different
- 3:15countries to track the Orion spacecraft
- 3:18during its journey around the moon. This
- 3:20is a significant expansion from the
- 3:22Aremis 1 mission which had only 10
- 3:25volunteers.
- 3:26>> So what exactly will these volunteers be
- 3:28doing?
- 3:29>> They'll be using their own equipment.
- 3:31Everything from established commercial
- 3:33service providers to university research
- 3:36facilities to individual amateur radio
- 3:39enthusiasts to passively track radio
- 3:42waves transmitted by Orion during its
- 3:45approximately 10day mission. We're
- 3:47talking about 47 ground assets spanning
- 3:50the globe.
- 3:51>> That's impressive international
- 3:53cooperation. Who made the cut?
- 3:55>> The list is quite diverse. Government
- 3:58agencies like the Canadian Space Agency
- 4:00and Germany's DLR are participating.
- 4:04Commercial companies include Goonhilly
- 4:06Earth Station in the UK, Kongsburg
- 4:09Satellite Services in Norway, and
- 4:11Intuitive Machines in Houston.
- 4:14Universities like UC Berkeley, the
- 4:16University of Pittsburgh, and even
- 4:18Morehead State University in Kentucky
- 4:20are involved.
- 4:22>> What about amateur radio operators?
- 4:24>> Oh, yes, they're well represented. We've
- 4:27got individuals like Chris Swire from
- 4:29South Dakota and Dan Slater from
- 4:32California. Amateur radio organizations
- 4:35from Argentina, Germany, the
- 4:37Netherlands, and France are also
- 4:39participating. It's truly a global
- 4:42effort.
- 4:43>> And this data they collect, what's NASA
- 4:45doing with it?
- 4:46>> The volunteers will submit their
- 4:48tracking data to NASA for analysis. This
- 4:51helps the agency assess the broader
- 4:53aerospace community's tracking
- 4:55capabilities and identify ways to
- 4:57augment future moon and Mars mission
- 4:59support. Kevin Coggins, NASA's deputy
- 5:03associate administrator for space
- 5:04communications and navigation, called it
- 5:07a real step toward SCAN's commercial
- 5:10first vision.
- 5:11>> Building that public private ecosystem
- 5:13for deep space exploration.
- 5:15>> Exactly. Now, let's shift gears to some
- 5:19groundbreaking lunar research.
- 5:21Scientists analyzing samples from
- 5:24China's Chonga 6 mission have made a
- 5:26discovery that helps explain one of the
- 5:29moon's most puzzling features,
- 5:31>> the asymmetry between the near and far
- 5:33sides.
- 5:34>> Precisely. You know how the near side of
- 5:36the moon has all those dark maria, those
- 5:39vast volcanic planes that formed the man
- 5:42in the moon pattern we're all familiar
- 5:44with? The far side has barely any.
- 5:47>> I've always found that fascinating. What
- 5:49did they discover?
- 5:50>> Tong A6 brought back samples from the
- 5:53south pole atkin basin, which is one of
- 5:55the largest impact features in the
- 5:57entire solar system, about 1,600 miles
- 6:01wide and between 4.2 2 and 4.3 billion
- 6:05years old. Much older than the lunar
- 6:07maria which are around 3.6 billion years
- 6:10old.
- 6:11>> And what did these ancient samples
- 6:12reveal?
- 6:13>> The research team led by Hang Ton from
- 6:16the Chinese Academy of Sciences found
- 6:19something unusual in the basaltic rock
- 6:21samples, an abnormal ratio of potassium
- 6:25isotopes. Specifically, they found more
- 6:27of the heavier potassium 41 relative to
- 6:31potassium 39 compared to samples from
- 6:33the near side.
- 6:35>> What would cause that?
- 6:36>> After exploring several possibilities,
- 6:39cosmic ray irradiation, magma processes,
- 6:42meteoritic contamination, they concluded
- 6:45that this isotopic signature is a relic
- 6:48of the giant impact that formed the
- 6:50south pole atkin basin itself. So the
- 6:54impact actually changed the moon's
- 6:55chemistry.
- 6:56>> Not just changed it, it fundamentally
- 6:59altered it. The impact was so violent
- 7:02that it heated the moon's crust and
- 7:04mantle intensely, causing many volatile
- 7:07elements, including potassium, to
- 7:09evaporate and escape into space. The
- 7:11lighter potassium 39 isotope evaporated
- 7:15more easily than the heavier one,
- 7:17leaving behind this unusual ratio.
- 7:20>> That's incredible detective work. And
- 7:22this explains the lack of maria on the
- 7:24far side.
- 7:25>> Exactly. The reduction in volatiles
- 7:27would have suppressed magma formation,
- 7:30limiting volcanism on the far side. It
- 7:32shows how deeply that ancient impact
- 7:35affected the moon's interior and why
- 7:37isotopic analysis can provide windows
- 7:40into the conditions of such catastrophic
- 7:42events. This research was published in
- 7:45the proceedings of the National Academy
- 7:47of Sciences.
- 7:48>> Fascinating stuff. Now, here's something
- 7:50a bit more down to earth, even if it's
- 7:52going to space. Anna, tell us about the
- 7:55startup that's making space memorials
- 7:57affordable.
- 7:58>> This is a really interesting story,
- 8:00Avery. A startup called Space Beyond,
- 8:03founded by Ryan Mitchell, is planning to
- 8:05send up to 1,000 people's ashes to space
- 8:08in October 2027 for as little as $249,
- 8:13dramatically cheaper than traditional
- 8:15space memorial services that typically
- 8:18cost thousands of dollars.
- 8:20>> That's quite a price difference. How are
- 8:21they pulling this off?
- 8:23>> It's all about smart use of existing
- 8:25infrastructure. They're using a Cubsat,
- 8:28one of those miniature cube- shaped
- 8:30satellites that will launch as a ride
- 8:32share payload on a SpaceX Falcon 9
- 8:34rocket. The ride share model has really
- 8:37democratized access to space.
- 8:39>> And Ryan Mitchell, he's got some serious
- 8:42space credentials. Right.
- 8:44>> Absolutely. He worked on NASA's space
- 8:46shuttle program and spent nearly a
- 8:48decade at Blue Origin. The idea actually
- 8:51came to him while attending a family
- 8:53member's ash spreading ceremony. He
- 8:55thought, "How could I do this better?"
- 8:57And thus, Space Beyond was born.
- 9:00>> But there must be some limitations with
- 9:02such an affordable service.
- 9:04>> There are customers can only send about
- 9:071 g of ashes, a practical limit due to
- 9:10weight considerations and the need to
- 9:12fit many customers remains in the Cubat.
- 9:15The satellite will only orbit for about
- 9:175 years before burning up in Earth's
- 9:19atmosphere. So, it's not forever. Though
- 9:22that fiery ending has a certain poetic
- 9:25quality to it.
- 9:26>> Mitchell certainly thinks so. Plus, the
- 9:28Cubat will be in a suns synchronous
- 9:30orbit at about 550 km altitude, meaning
- 9:34it'll fly over the entire globe. With
- 9:37modern spacecraft tracking services,
- 9:39families should be able to locate it and
- 9:41know when it's passing overhead.
- 9:44>> That's actually really touching. And
- 9:46importantly, they're not spreading the
- 9:48ashes in space. Right.
- 9:50>> Correct. Mitchell called that an almost
- 9:52nightmare scenario because the particles
- 9:54could create a debris cloud that could
- 9:56endanger other spacecraft. Since
- 9:59customers only send about a gram, they
- 10:01can do what they wish with the rest.
- 10:03>> Thoughtful approach to a sensitive
- 10:05service. Now, let's talk about something
- 10:07that might literally redefine astronomy.
- 10:10Anna, tell us about this massive
- 10:12potential exomoon.
- 10:14>> This one's mindbending, Avery.
- 10:17Astronomers using the gravity instrument
- 10:19on the Very Large Telescope in Chile
- 10:21have detected what might be an exomoon
- 10:24orbiting the gas giant HD206893b
- 10:29located 133 light years from Earth. But
- 10:32here's the kicker. This moon is so
- 10:35massive that it might force us to
- 10:37rethink the word moon even means.
- 10:40>> How massive are we talking?
- 10:42>> Get this. They estimate it could be as
- 10:44much as 40% the mass of Jupiter or about
- 10:48nine times the mass of Neptune. To put
- 10:50that in perspective, it's thousands of
- 10:52times heavier than any moon in our solar
- 10:55system. Anamine, Jupiter's largest moon
- 10:58and the biggest in our solar system, is
- 11:00thousands of times less massive than
- 11:02Neptune.
- 11:03>> Wow. So, how did they even detect
- 11:05something like this? Through a technique
- 11:08called astrometry, which precisely
- 11:10tracks the position of celestial bodies
- 11:12over time, the team led by Quentyn Crawl
- 11:15from the University of Cambridge
- 11:17observed a measurable wobble in HD
- 11:20206893b's
- 11:22motion, a back and forth movement with a
- 11:25period of about 9 months.
- 11:27>> And that wobble is the moon's
- 11:29gravitational tug.
- 11:30>> Exactly. PL explained that the wobble
- 11:33has a size comparable to the Earth moon
- 11:35distance, which is the exact signature
- 11:38you'd expect from an unseen companion.
- 11:40The potential moon's orbit is also
- 11:42tilted by roughly 60°, suggesting a
- 11:46turbulent history of gravitational
- 11:48interactions.
- 11:49>> So, at what point does something stop
- 11:51being a moon and become a binary
- 11:53companion?
- 11:54>> That's the milliondoll question. Crawl
- 11:57noted that at these masses, the
- 11:59distinction between a massive moon and a
- 12:01low mass companion becomes blurred.
- 12:03There's currently no official definition
- 12:06of an exomoon. So, astronomers generally
- 12:08refer to any object orbiting a planet as
- 12:11a moon.
- 12:12>> This could force a redefin
- 12:14>> potentially. Crawl suggested that as
- 12:17observational techniques improve, our
- 12:19definitions and understanding of what
- 12:21constitutes a moon will almost certainly
- 12:24evolve. He also pointed out that we're
- 12:26likely only seeing the tip of the
- 12:28iceberg. Just as the first exoplanets
- 12:31discovered were massive ones close to
- 12:33their stars because they were easiest to
- 12:35detect, the first exomoons we identify
- 12:37will be the most massive and extreme
- 12:40examples.
- 12:41>> Finding exomoons is challenging. I
- 12:44imagine
- 12:45>> extremely the signals they produce are
- 12:47minute, often lost in the noise of their
- 12:50parent planet's data. The transit method
- 12:53that's revolutionized exoplanet
- 12:55discovery is less effective for moons
- 12:58because they produce light dips too
- 13:00faint to distinguish. But astrometry
- 13:03offers a new path forward, especially
- 13:05for detecting companions in far orbits
- 13:08where large stable moons are more likely
- 13:11to exist.
- 13:12>> This research was published in astronomy
- 13:15and astrophysics. It's been accepted for
- 13:18publication there and it's currently
- 13:19available as a pre- peer-reviewed paper
- 13:22on archive. If confirmed, this would not
- 13:24only expand our catalog of celestial
- 13:27bodies, but force astronomers to rethink
- 13:30one of the oldest definitions in
- 13:32planetary science.
- 13:34>> Incredible. And finally, Anna, we have a
- 13:36story that might rewrite history or at
- 13:39least rename a famous comet.
- 13:41>> That's right. New research suggests that
- 13:44Haley's comet might be wrongly named.
- 13:47Turns out an 11th century English monk
- 13:49named Elmer of Malmsbury understood the
- 13:52comet's periodic nature centuries before
- 13:55the British astronomer Edmund Haley.
- 13:58>> Wait, so Halley wasn't the first to
- 14:00figure this out? According to research
- 14:02by professor Simon Portiges wart and
- 14:05colleagues published in the book
- 14:07Doristad and everything after Ilmer
- 14:10witnessed Haley's comet twice in 989 CE
- 14:14and again in 1066 CE and realized it was
- 14:17the same comet returning.
- 14:20>> How do we know this?
- 14:21>> The events are described by the 12th
- 14:23century chronicler William of Malssbury.
- 14:26But this connection had gone unnoticed
- 14:28by scholars until now. The 1066
- 14:32appearance is actually depicted on the
- 14:34famous Bayou tapestry which illustrates
- 14:36the events of that year including the
- 14:39Norman conquest of England.
- 14:41>> So Ilmer must have been quite elderly to
- 14:43see it twice.
- 14:45>> Exactly. Given that the comet appears
- 14:47roughly 76 years, he would have been
- 14:50advanced in age when he witnessed it for
- 14:52the second time. And here's a
- 14:55fascinating detail. As was customary at
- 14:58the time when he saw it in 1066, the
- 15:01king was warned of impending disaster.
- 15:04The comet appeared during the brief
- 15:06reign of King Harold Godwinson, who died
- 15:09at the Battle of Hastings that October.
- 15:12>> Medieval people really did see comets as
- 15:14omens, didn't they?
- 15:16>> They did indeed. The research shows that
- 15:18comet appearances around this time were
- 15:21consistently associated with the deaths
- 15:23of kings, war, or famine in the British
- 15:26Isles. The researchers even found what
- 15:28might be historical fake news. A comment
- 15:31supposedly seen before the death of
- 15:33Archbishop Cydrich of Canterbury in 995,
- 15:36which wasn't actually recorded in the
- 15:38Chronicles, possibly an exaggeration to
- 15:41frighten people.
- 15:42>> So, what are the researchers calling
- 15:44for? They're arguing that Haley's comet
- 15:47should be given a different name since
- 15:48it had been observed twice and its
- 15:50periodicity understood centuries before
- 15:53Haley's work. Portuge's wart mentioned
- 15:56that while the research was fun to do,
- 15:58it was challenging working in such an
- 16:00interdisciplinary project alongside a
- 16:02historian. Nevertheless, they plan to
- 16:05carry out further research into periodic
- 16:07comet.
- 16:08>> It's amazing how interdisciplinary
- 16:10research can uncover these historical
- 16:12oversightes. It really is. And it shows
- 16:15that scientific discovery isn't always
- 16:18about new observations. Sometimes it's
- 16:20about looking at old records with fresh
- 16:23eyes. Well, that's all the time we have
- 16:25for today's episode. What a journey
- 16:27we've been on. From rocket fairings to
- 16:29ancient lunar impacts, affordable space
- 16:32memorials to massive exomoons, and
- 16:34historical comet discoveries.
- 16:37>> It never ceases to amaze me how much is
- 16:39happening in space and astronomy every
- 16:42single day. From cutting edge
- 16:44engineering to billion-year-old
- 16:45mysteries, there's always something new
- 16:47to learn.
