Transcript
- 0:00Welcome to Astronomy Daily. I'm Anna.
- 0:03>> And I'm Avery. It's Friday, January
- 0:0623rd, and we've got an amazing lineup of
- 0:08space stories to close out your week.
- 0:10>> We certainly do. Today, we're exploring
- 0:13NASA's plans to send some very special
- 0:16keepsakes around the moon on Artemis 2,
- 0:19Blue Origin's latest new Glenn launch
- 0:22plans, and some fascinating new research
- 0:24about where Earth's water really came
- 0:27from. Plus, we'll dive into a rather
- 0:29urgent warning about the increasing
- 0:31dangers of space debris, uncover new
- 0:33insights about how super massive black
- 0:35holes grew so quickly, and learn how AI
- 0:38is helping scientists discover thousands
- 0:40of new exoplanets. Let's get started.
- 0:43>> Avery, as Artemis 2 preparations
- 0:46continue at Kennedy Space Center, NASA
- 0:49has revealed something really special
- 0:51they'll be taking along for the ride.
- 0:53And it's not just the four astronauts.
- 0:55Oh, I love when missions carry
- 0:57meaningful items. What are they
- 0:59bringing?
- 1:00>> This is fascinating. The official flight
- 1:02kit includes a piece of fabric from the
- 1:05original 1903 Wright flyer. It's a tiny
- 1:08swatch just 1 in square from the very
- 1:11first aircraft that made the powered
- 1:13flight at Kittyhawk. What's even cooler
- 1:16is that this same piece already flew on
- 1:18the space shuttle Discovery back in
- 1:201985.
- 1:22So, it's making its second journey to
- 1:24space. That's a beautiful connection
- 1:26between the beginning of powered flight
- 1:28and humanity's return to the moon. What
- 1:31else is in the flight kit?
- 1:32>> Bears an American flag with an
- 1:34incredible history. It flew on the very
- 1:36first shuttle mission, STS1, and the
- 1:40final shuttle mission, STS135.
- 1:43It also went up on SpaceX's first crude
- 1:46Dragon flight. Talk about bookending an
- 1:49era of space flight. That flag has seen
- 1:51some serious history. Is there anything
- 1:53connecting Artemis back to the Apollo
- 1:55program?
- 1:56>> Absolutely. They're flying a flag that
- 1:58was originally meant for Apollo 18, a
- 2:01mission that never happened. This will
- 2:04be its very first space flight, finally
- 2:06fulfilling its original destiny after
- 2:08all these years. There's also a photo
- 2:11negative from the Ranger 7 mission,
- 2:13which was the US first spacecraft to
- 2:16successfully reach the lunar surface
- 2:18back in the 1960s.
- 2:20>> It's like they're weaving together the
- 2:21entire story of American exploration.
- 2:24And knowing NASA, I bet they're
- 2:26including the public somehow.
- 2:27>> Of course, an SD card carrying millions
- 2:30of names, including ours, from the send
- 2:33your name to space campaign, will be
- 2:35aboard. NASA administrator Jared
- 2:38Isaacman put it beautifully when he
- 2:40said, "These artifacts reflect the long
- 2:42arc of American exploration and the
- 2:45generations of innovators who made this
- 2:47moment possible." With about 10 lbs of
- 2:50momentos in total, Artemis 2 will truly
- 2:53be carrying our collective history and
- 2:56dreams forward into the next chapter
- 2:58beyond Earth.
- 2:59>> What a perfect way to mark America's
- 3:01250th anniversary. Now, speaking of
- 3:04missions and launches, let's shift gears
- 3:06to Blue Origin and their New Glenn
- 3:08rocket.
- 3:09>> Blue Origin has announced their third
- 3:11New Glenn launch is scheduled for late
- 3:13February. And there's an interesting
- 3:16twist to this one.
- 3:17>> Let me guess, everyone expected them to
- 3:19fly their Blue Moon lunar lander next.
- 3:21Right.
- 3:22>> Exactly. But instead, they're launching
- 3:24a satellite for AS Space Mobile, making
- 3:28it the second commercial payload to fly
- 3:30on New Glenn. The Blue Moon Mark1 lander
- 3:33is currently being shipped to NASA's
- 3:35Johnson Space Center for vacuum chamber
- 3:37testing, and they haven't announced a
- 3:39launch date for that mission yet.
- 3:41>> So, what makes this particular launch
- 3:43notable?
- 3:44>> This will be the third new Glenn launch
- 3:46in just over a year, which is impressive
- 3:49considering the rocket spent a decade in
- 3:51development. But here's the really
- 3:53exciting part. They're reusing the
- 3:55booster from November's second flight.
- 3:58They successfully landed it on a drone
- 4:00ship in the ocean just like SpaceX does
- 4:02with Falcon 9.
- 4:04>> So, this demonstrates their reusability
- 4:07program is working. That's crucial for
- 4:09reducing launch costs. What else is Blue
- 4:12Origin working on?
- 4:13>> They've got some ambitious plans. In
- 4:16November, they revealed a Superheavy
- 4:18variant of New Glenn that will be taller
- 4:21than a Saturn 5 rocket on par with
- 4:24SpaceX's Starship. And just this week,
- 4:26they announced a satellite internet
- 4:28constellation called Terrowave that they
- 4:31plan to start deploying in late 2027.
- 4:34>> February is shaping up to be a busy
- 4:36month for space flight. NASA might
- 4:38launch Artemis 2 as early as February
- 4:416th. SpaceX is testing the third version
- 4:44of Starship and Crew 12 to the
- 4:46International Space Station is also
- 4:48scheduled. Speaking of busy orbital
- 4:50environments, that brings us to our next
- 4:52story about space debris. Avery, this
- 4:55next story is both fascinating and a bit
- 4:58alarming. A new study has introduced
- 5:01something called the crash clock. And
- 5:03according to their calculations, if
- 5:05satellite operators suddenly lost the
- 5:08ability to maneuver their spacecraft, we
- 5:10could see a catastrophic collision in
- 5:12just 5.5 days.
- 5:15>> Wait, 5.5 days? That's incredibly short.
- 5:19What's driving this?
- 5:21>> Mega constellations. The researchers
- 5:23found that close approaches between
- 5:25satellites, defined as two satellites
- 5:27passing within 1 kilometer of each
- 5:29other, now happen every 22 seconds
- 5:32across all low Earth orbit mega
- 5:35constellations. For Starlink alone, it's
- 5:37once every 11 minutes. Each Starling
- 5:40satellite performs an average of 41
- 5:43avoidance maneuvers per year.
- 5:45>> Those numbers are staggering. And you
- 5:48said 5.5 days. I thought I'd heard this
- 5:51was originally 2.8 days.
- 5:53>> Good catch. The team updated their model
- 5:56based on community feedback. The
- 5:58original calculation was 2.8 days, but
- 6:00after incorporating expert input, they
- 6:03revised it to 5.5 days for 2025 data. By
- 6:07comparison, back in 2018, before the
- 6:10mega constellation era really took off,
- 6:12it would have taken 164 days before a
- 6:16collision. So, we've gone from 164 days
- 6:19down to 5.5 days in just 7 years. What
- 6:23could cause operators to lose control
- 6:25like that?
- 6:26>> Solar storms are the main threat. When a
- 6:28coronal mass ejection hits Earth, it
- 6:31heats up the upper atmosphere, creating
- 6:33more drag on satellites and making their
- 6:35trajectories harder to predict. During
- 6:38the Ganon storm in May 2024, over half
- 6:41of all satellites in low Earth orbit had
- 6:43to use fuel for repositioning maneuvers.
- 6:46More seriously, solar storms can knock
- 6:49out satellites navigational and
- 6:50communication systems, leaving them
- 6:52unable to maneuver at all.
- 6:55>> And solar storms don't give us much
- 6:57warning, do they?
- 6:58>> Typically, just a day or two at most.
- 7:01The study found that within 24 hours of
- 7:03losing maneuvering capability, there's a
- 7:0630% chance of a collision between
- 7:08tracked objects and a 26% chance of a
- 7:11collision involving a Starlink satellite
- 7:13specifically. Such collisions would be
- 7:15catastrophic, creating major debris
- 7:18generating events with high likelihood
- 7:20of secondary and tertiary collisions.
- 7:23That sounds like Kesler syndrome. The
- 7:26cascade effect where collisions create
- 7:28debris that causes more collisions.
- 7:30>> Exactly. Though the researchers want to
- 7:33be clear about something important. Lead
- 7:35author Sarah Theal emphasized they're
- 7:37not saying Kesler syndrome is days away.
- 7:40The crash clock only measures time to
- 7:42the first collision, not a runaway
- 7:45cascade. Bull Kesler syndrome would take
- 7:47decades or even centuries to develop.
- 7:50But the clock does show how reliant we
- 7:52are on errorless operations every single
- 7:55day.
- 7:56>> So it's more of a stress indicator for
- 7:58the orbital environment.
- 8:00>> Right. The team suggests the crash clock
- 8:03could serve as a key environmental
- 8:05indicator similar to how we use carbon
- 8:07emissions metrics for climate change.
- 8:10They're calling for improved debris
- 8:12mitigation, coordinated traffic
- 8:14management, and stronger space weather
- 8:16resilience measures to protect the
- 8:18technology modern society depends on.
- 8:22Now, let's shift from orbital concerns
- 8:24to lunar mysteries.
- 8:27>> For decades, Anna, scientists have
- 8:29assumed that Earth's water was delivered
- 8:31by asteroids and comets during the late
- 8:33heavy bombardment about 4 billion years
- 8:35ago. But new research from lunar samples
- 8:38is challenging that assumption.
- 8:39>> The Apollo samples are still teaching us
- 8:42new things after all these years. What
- 8:45did they find?
- 8:46>> Dr. Tony Gargano at the Lunar and
- 8:48Planetary Institute led a team that
- 8:50analyzed lunar rocks and regalith using
- 8:52high precision triple oxygen isotopes.
- 8:55They found that meteorites could only
- 8:57have supplied a small fraction of
- 8:58Earth's water, even by the most generous
- 9:01estimates. The lunar surface record sets
- 9:04a hard limit on volatile delivery.
- 9:06>> Why is the moon such a good record
- 9:08keeper for this?
- 9:10>> On Earth, tectonic plates constantly
- 9:12renew the surface, erasing traces of
- 9:14ancient impacts. But the moon is airless
- 9:16and hasn't had geological activity for
- 9:19billions of years. So, its geological
- 9:21records since the late heavy bombardment
- 9:23has been carefully preserved. It's like
- 9:25a cosmic history book that hasn't been
- 9:27edited. How did they approach the
- 9:29analysis differently from previous
- 9:31studies?
- 9:32>> Instead of focusing on metal loving
- 9:34elements like previous researchers,
- 9:36Gargano's team analyzed oxygen isotopes
- 9:39which make up the largest mass fraction
- 9:41of rocks. The oxygen triple isotope
- 9:44signature can separate two things that
- 9:46are often confused in lunar regalith.
- 9:48The addition of impactor material and
- 9:50the effects of impact induced
- 9:52vaporization on isotopic composition.
- 9:55And what did the oxygen isotopes tell
- 9:57them?
- 9:58>> They found that at least 1% of the
- 9:59moon's mass consists of impact related
- 10:02material, likely from carbonatous
- 10:04meteorites that partially vaporized on
- 10:06impact. From this, they calculated that
- 10:09only a tiny amount of water has been
- 10:11delivered to the Earth moon system since
- 10:13the late heavy bombardment compared to
- 10:15Earth's existing water.
- 10:16>> To put that in perspective, how much
- 10:18water does Earth have? Water covers over
- 10:2171% of Earth's surface, but it only
- 10:24accounts for about 0.023%
- 10:27of Earth's total mass. That still works
- 10:30out to roughly 1.466
- 10:33kg. That's 1.46 followed by 21.
- 10:38So even a tiny fraction of that is
- 10:40significant.
- 10:40>> Co-author Dr. Justin Simon from NASA
- 10:44summed it up well. The results don't say
- 10:46meteorites delivered no water, but they
- 10:49do make it very hard for late meteorite
- 10:51delivery to be the dominant source of
- 10:54Earth's oceans.
- 10:55>> This has interesting implications for
- 10:57lunar exploration, doesn't it?
- 10:59>> Absolutely. While meteorites may have
- 11:02delivered only a tiny fraction of
- 11:04Earth's water, their contribution could
- 11:06be crucial for the moon. Water ice in
- 11:09permanently shadowed regions is
- 11:11essential for establishing a sustained
- 11:13human presence, providing drinking
- 11:15water, irrigation, radiation shielding,
- 11:18and the means to make rocket propellant.
- 11:21As the researchers noted, that small
- 11:23amount of water delivered by impacts
- 11:26could be the single most important
- 11:28factor enabling humanity's expansion
- 11:31into space. From water on the moon to
- 11:34mysteries in the early universe, let's
- 11:36talk about super massive black holes.
- 11:38>> How did black holes get so big so fast?
- 11:42That's been one of astronomy's great
- 11:44mysteries, Avery. And researchers at
- 11:46Ireland's May University have found an
- 11:49answer.
- 11:50>> The James Webb Space Telescope has been
- 11:52finding these massive black holes in the
- 11:54early universe that shouldn't exist
- 11:56according to our previous models. Right.
- 11:58>> Exactly. These super massive black holes
- 12:01existed just a few hundred million years
- 12:04after the big bang and conventional
- 12:06theories said there wasn't enough time
- 12:08for them to grow so large. The May team
- 12:11led by PhD candidate Daxel Ma used
- 12:14state-of-the-art computer simulations to
- 12:17reveal what happened
- 12:18>> and what did they discover? The chaotic
- 12:21conditions in the early universe
- 12:23triggered these smaller black holes to
- 12:25undergo what they call a feeding frenzy,
- 12:28devouring material all around them. The
- 12:31dense gas-rich environments in early
- 12:33galaxies enabled something called
- 12:36superdington accretion.
- 12:38>> Super Edington accretion. That sounds
- 12:41intense. What is it?
- 12:42>> It's when a black hole eats matter
- 12:45faster than what's considered normal or
- 12:47safe. Normally, when matter falls into a
- 12:50black hole that quickly, it should blow
- 12:53the food away with radiation pressure.
- 12:55But somehow, in these early dense
- 12:58environments, the black holes kept
- 13:00eating anyway, growing incredibly fast
- 13:04into tens of thousands of times the mass
- 13:07of our sun.
- 13:08>> So, they found the missing link between
- 13:10the first stars and later super massive
- 13:12black holes.
- 13:14>> Yes, black holes come in two main seed
- 13:17types. light seeds, which start at only
- 13:19about 10 to a few hundred times the mass
- 13:22of our sun, and heavy seeds, which can
- 13:24start at up to 100,000 solar masses.
- 13:28Previously, astronomers thought you
- 13:30needed those rare heavy seeds to explain
- 13:33super massive black holes. But this
- 13:35research shows that common light seed
- 13:38black holes can grow at extreme rates
- 13:40under the right conditions.
- 13:42>> Dr. John Regan from the team put it
- 13:44perfectly when he said, "Heavy seeds are
- 13:46somewhat exotic and may need rare
- 13:48conditions to form, but their
- 13:50simulations show that garden variety
- 13:52stellar mass black holes can grow at
- 13:54extreme rates in the early universe."
- 13:56>> This has implications beyond just
- 13:59understanding the past. The research
- 14:01team noted that future gravitational
- 14:03wave observations from the LISA mission
- 14:06scheduled to launch in 2035 may be able
- 14:09to detect the mergers of these tiny
- 14:12early rapidly growing baby black holes.
- 14:15It's exciting to think we might actually
- 14:17observe these processes directly. From
- 14:20black holes to exoplanets, let's close
- 14:22with our final story about AI hunting
- 14:24for new worlds. Anna, we found over
- 14:276,000 exoplanets so far with more than
- 14:30half discovered using data from NASA's
- 14:32Kepler and test missions, but there's
- 14:34still a treasure trove of data waiting
- 14:36to be analyzed. And that's where
- 14:38artificial intelligence comes in.
- 14:40>> I remember hearing about Exomminer back
- 14:42in 2021. Is that what this is about?
- 14:45>> Exactly. The team at NASA's AS research
- 14:48center created exomminer, which used AI
- 14:51to validate 370 new exoplanets from
- 14:55Kepler data. Now, they've released
- 14:57Exomminer Plus+ trained on both Kepler
- 15:00and test data, and the results are
- 15:02impressive.
- 15:03>> What can the new version do?
- 15:05>> On its initial run of test data, Exom
- 15:08Miner++ identified 7,000 targets as
- 15:11exoplanet candidates. These are signals
- 15:13that are likely to be planets, but
- 15:15require follow-up observations to
- 15:17confirm. The software sifts through
- 15:19observations of possible transits, those
- 15:22tiny dips in starlight when a planet
- 15:24passes in front of its host star, and
- 15:26predicts which ones are real planets
- 15:28versus other phenomena like eclipsing
- 15:30binary stars.
- 15:31>> And this is all open-source software.
- 15:34>> Yes, anyone can download it from GitHub
- 15:36and use it to hunt for planets in TESS's
- 15:38growing public data archive. Kevin
- 15:41Murphy, NASA's chief science data
- 15:43officer, emphasized that open-source
- 15:45software like Exom Minor accelerates
- 15:47scientific discovery. When researchers
- 15:49freely share their tools, it lets others
- 15:52replicate results and dig deeper into
- 15:54the data.
- 15:55>> What makes Exomminer Plus+ particularly
- 15:58effective?
- 15:59>> Miguel Martinho, the co-investigator,
- 16:01explains that when you have hundreds of
- 16:03thousands of signals like this, it's the
- 16:05ideal place to deploy deep learning
- 16:07technologies. Despite Kepler and TESS
- 16:10operating differently, TESS surveys
- 16:12nearly the whole sky looking for planets
- 16:14around nearby stars, while Kepler looked
- 16:17at a small patch of sky more deeply. The
- 16:19two missions produce compatible data
- 16:21sets. This allows Exomminer Plus+ to
- 16:24train on both and deliver strong
- 16:26results.
- 16:27>> Project lead Jameid again said it
- 16:29perfectly. With not many resources, they
- 16:32can make a lot of returns. What's next
- 16:34for the program? The team is working on
- 16:36giving the model the ability to identify
- 16:38transit signals themselves from raw data
- 16:41rather than just evaluating
- 16:42pre-identified candidates. And looking
- 16:45ahead, NASA's Nancy Grace Roman Space
- 16:47Telescope will capture tens of thousands
- 16:50of exoplanet transits starting in a few
- 16:52years. And all that data will be freely
- 16:54available, too. The advances made with
- 16:56Exomminer could help hunt for planets in
- 16:58Roman data as well.
- 17:00>> Exoplanet scientist John Jenkins summed
- 17:02it up beautifully. Open source science
- 17:05and open-source software are why the
- 17:07exoplanet field is advancing as quickly
- 17:09as it is. It's a great reminder of how
- 17:12collaboration and shared resources drive
- 17:14discovery.
- 17:15>> And that's all we have time for today.
- 17:18What a day of space news, Anna. From
- 17:20legacy keepsakes heading to the moon to
- 17:22urgent warnings about orbital debris to
- 17:25AI discovering thousands of new worlds
- 17:27>> and everything in between. New insights
- 17:30about Earth's water, the rapid growth of
- 17:32super massive black holes, and Blue
- 17:35Origin's expanding launch manifest.
- 17:37Space exploration continues to
- 17:39accelerate on multiple fronts.
- 17:41>> That's it for today's episode of
- 17:42Astronomy Daily. Thanks for joining us,
- 17:44and we'll see you tomorrow. Keep looking
- 17:46up.
- 17:47>> Clear skies, everyone. Astronomy day.
- 17:51The stories be told.
- 18:00Stories told.
