Latest / Space News Today / Wheelchair Astronaut, Cosmic Fireworks, and the Race to Mine the Moon
Transcript
- 0:00Welcome to Astronomy Daily, your source
- 0:02for the latest news from across the
- 0:04cosmos. I'm Avery.
- 0:06>> And I'm Anna. It's great to be with you
- 0:09today, Avery. We're talking about
- 0:11everything from the first wheelchair
- 0:12user heading to space to a star system
- 0:15that's getting ready to put on a
- 0:17celestial fireworks show.
- 0:19>> Absolutely. We'll also be diving into a
- 0:21new survey of our galactic neighbors, a
- 0:24surprising discovery about the sun, the
- 0:26new race to mine the moon, and the
- 0:28incredible tech being built to study the
- 0:30planet right next door. Let's get
- 0:33started. First up, a truly historic
- 0:36mission from Blue Origin. They're
- 0:37targeting December 18th for their NS-37
- 0:40mission, and it's a huge step forward
- 0:42for accessibility in space.
- 0:44>> It really is. On board the new Shepard
- 0:47vehicle will be Michaela Bentthouse, an
- 0:49aerospace engineer at the European Space
- 0:52Agency who is set to become the first
- 0:54wheelchair user to fly to space.
- 0:56>> That's just fantastic. And she's not
- 0:58just a passenger. She's an aerospace
- 1:00engineer herself. That adds another
- 1:03layer to this.
- 1:04>> Exactly. It's not just about tourism.
- 1:06It's about opening up the field of space
- 1:08exploration to talented professionals
- 1:10who might have been excluded in the
- 1:12past. It's a suborbital flight lasting
- 1:14about 10 minutes, but it sends a
- 1:16powerful message that space is for
- 1:18everyone.
- 1:19>> It really challenges the old right stuff
- 1:21astronaut mold. And she'll be joined by
- 1:23a pretty interesting crew, including
- 1:25investors and even a former top engineer
- 1:28from SpaceX, Hans Coningsman. And it's
- 1:31not just a symbolic gesture. The
- 1:33engineering that goes into making a
- 1:34spacecraft accessible for someone with
- 1:36different physical needs is non-trivial.
- 1:39It forces designers to rethink
- 1:41everything from seating and restraints
- 1:43to how crew members interact with the
- 1:45cabin in microgravity. These are
- 1:47solutions that could benefit all future
- 1:49astronauts.
- 1:50>> Mhm. A diverse group for a landmark
- 1:53flight. We wish the entire NS37 crew a
- 1:56safe and incredible journey. All right,
- 1:59let's shift our focus from low Earth
- 2:01orbit to our nearest galactic neighbors,
- 2:03the Magelenic clouds. A major new survey
- 2:06is about to give us an unprecedented
- 2:08look at these satellite galaxies.
- 2:10>> Ah, yes, the large and small mellic
- 2:13clouds. For listeners in the northern
- 2:15hemisphere, they might not be familiar,
- 2:16but they're a stunning site from
- 2:18southern latitudes. So, what's this new
- 2:21survey, the 101 MC all about?
- 2:24>> The key is the technology. It's a 5-year
- 2:26survey using the foremost instrument on
- 2:29the Vista telescope in Chile. Now past
- 2:31surveys have given us beautiful images
- 2:33which is called photometry measuring
- 2:36brightness and position. This one is all
- 2:38about spectroscopy.
- 2:40>> Right? So spectroscopy breaks down the
- 2:42star light into its component
- 2:44wavelengths like a fingerprint. What can
- 2:46that fingerprint tell us?
- 2:48>> It tells us so much more. We can learn a
- 2:50stars chemical composition, its
- 2:52temperature, how fast it's moving toward
- 2:54or away from us, and even how quickly
- 2:56it's spinning by gathering spectra for
- 2:59about half a million stars. This survey
- 3:01will create a detailed 3D map of the
- 3:03cloud's chemistry and motion.
- 3:05>> And that helps us understand how they're
- 3:07interacting with our Milky Way. Right.
- 3:09I've read about the Magelenic Stream,
- 3:11that huge river of gas being pulled from
- 3:14the clouds by our galaxy's gravity.
- 3:16>> Precisely. This data led by Dr. Laura
- 3:19Cullinine's group will give us the
- 3:20missing link to model that interaction
- 3:22accurately. It will help us piece
- 3:24together the history of this cosmic
- 3:26dance and predict the ultimate fate of
- 3:28these two small galaxies.
- 3:30>> So, this isn't just about taking a
- 3:32picture. It's about conducting a census,
- 3:34a cosmic demographic survey. Are we
- 3:37looking at a timeline of years or
- 3:39decades before we can start drawing
- 3:41major conclusions from this data? The
- 3:43survey itself runs for 5 years, but
- 3:45initial data releases will likely happen
- 3:47along the way. The full impact will
- 3:49unfold over the next decade as theorists
- 3:52use this incredibly rich data set to
- 3:54refine their models of galaxy formation
- 3:56and evolution. It's a foundational
- 3:59project.
- 4:00>> From a cosmic dance to a cosmic U-turn,
- 4:03NASA's Parker Solar Probe has captured
- 4:06some incredible footage from its journey
- 4:08to touch the sun.
- 4:09>> This is genuinely surprising. During its
- 4:12closest approach, the probe observed a
- 4:15coronal mass ejection or CME. This is a
- 4:18massive eruption of solar material and
- 4:21magnetic fields from the sun.
- 4:23>> Mhm. And we usually think of CMEs as a
- 4:25one-way street blasting out into space.
- 4:28If they're aimed at Earth, they can
- 4:30cause geomagnetic storms and the aurora.
- 4:33>> That's the conventional picture. But
- 4:35Parker's images clearly show that not
- 4:37all the material escapes. A significant
- 4:40portion actually slows down, reverses
- 4:43course, and falls back toward the sun in
- 4:45these elongated blobs, which scientists
- 4:48are calling inflows.
- 4:50>> So, the sun is recycling its own
- 4:52magnetic fields. What does that mean for
- 4:54us? Does this change how we predict
- 4:56space weather?
- 4:57>> It could. Understanding this recycling
- 5:00process gives us a more complete model
- 5:02of the sun's magnetic activity. Better
- 5:05models mean better forecasts, which is
- 5:07vital for protecting our satellites,
- 5:09power grids, and astronauts from the
- 5:11most intense solar storms. This is the
- 5:14first time we've seen it so clearly, and
- 5:16it's a huge new piece of the solar
- 5:18puzzle.
- 5:19>> Okay. From solar physics to lunar
- 5:21politics, Anna, there's a new space race
- 5:24underway. But it's not about planting
- 5:26flags. It's about mining the moon.
- 5:29>> That's right. The ambition has moved
- 5:31from exploration to exploitation. We
- 5:33have nations and a growing number of
- 5:35private companies like Interoon and
- 5:37Astrobotic actively developing
- 5:40technologies to extract lunar resources.
- 5:42And the resources thereafter are
- 5:44incredibly valuable for future space
- 5:46travel. You have water ice which can be
- 5:48turned into rocket fuel and helium 3 for
- 5:51potential fusion reactors.
- 5:53>> The potential is enormous. The moon
- 5:56could become a critical staging post for
- 5:58the rest of the solar system. But this
- 6:00gold rush mentality is raising serious
- 6:02concerns. We're talking about the risk
- 6:05of environmental damage to a pristine
- 6:07world and the potential for geopolitical
- 6:09conflict over the most resourcerich
- 6:12areas.
- 6:13>> And we don't really have any rules for
- 6:14this, do we? The Outer Space Treaty of
- 6:171967 feels completely outdated.
- 6:20>> It's woefully insufficient. It says no
- 6:23nation can own the moon, but it's silent
- 6:25on whether a private company can own the
- 6:28resources it extracts. It's a huge legal
- 6:30vacuum. International bodies are trying
- 6:33to hash out new agreements like the
- 6:35Aremis Accords, but there's no global
- 6:38consensus yet.
- 6:39>> And that lack of consensus is the real
- 6:41danger. Without clear, internationally
- 6:44agreed upon rules, you risk a first
- 6:46come, first serve situation that could
- 6:48lead to disputes and even sabotage.
- 6:51Establishing a framework for peaceful,
- 6:53sustainable resource use is as critical
- 6:55as developing the technology to get
- 6:57there.
- 6:58>> Let's wish the policy makers well then.
- 7:01>> Indeed, we're essentially heading into a
- 7:03wild west scenario on the moon. This is
- 7:06a story we will definitely be following
- 7:08closely.
- 7:09>> Let's turn our gaze now to a different
- 7:11kind of cosmic event on the horizon.
- 7:13There's a star system called V Sagitta
- 7:15that astronomers are watching very, very
- 7:18closely. Right. This is a future
- 7:20headliner. So, V Sagitta is a binary
- 7:24system. Two stars orbiting each other.
- 7:26What makes this pair so special? It's
- 7:29what they call a cataclysmic variable.
- 7:31One star is a white dwarf, the
- 7:33incredibly dense collapsed core of a
- 7:35dead star. It's pulling in a stream of
- 7:38gas from its larger companion star, and
- 7:40it's doing so at an unprecedented
- 7:42accelerating rate. And when that stolen
- 7:45gas builds up on the surface of the
- 7:47super dense white dwarf, boom,
- 7:49>> boom is right. The immense pressure and
- 7:52temperature will ignite a runaway
- 7:54thermonuclear reaction, a nova.
- 7:57Astronomers predict this will happen in
- 7:59the coming years. And when it does, the
- 8:01system will brighten so dramatically it
- 8:03will likely be one of the brightest
- 8:05stars in our night sky, easily visible
- 8:07to the naked eye.
- 8:09>> That's incredible. But that's not even
- 8:11the grand finale, is it? Not at all.
- 8:14This process is causing the two stars to
- 8:16spiral closer and closer together.
- 8:19Eventually, they will collide and merge,
- 8:21triggering a full-blown supernova. The
- 8:24resulting explosion will be so
- 8:26mindbogglingly bright, it might even be
- 8:29visible during the daytime, an amazing,
- 8:32if violent, astronomical event in the
- 8:34making.
- 8:35>> Do we have a more precise prediction
- 8:38than in the coming years? Is this
- 8:40something we might see in our lifetimes?
- 8:42The models based on decades of
- 8:44observation of its accelerating orbital
- 8:46decay point to a date around 2083, plus
- 8:50or minus a decade. So yes, it's very
- 8:53likely to happen within the lifetime of
- 8:55many people listening today. It's a rare
- 8:57chance to watch a celestial forecast
- 8:59come true. For our final story, we're
- 9:02going from a system far away to the one
- 9:05right next door. We're talking about
- 9:07Proxima Centauri and its famous
- 9:09exoplanet Proxima B. That's right.
- 9:12Proxima B is our nearest exoplanet
- 9:15neighbor, which makes it a tantalizing
- 9:17target. But studying it is one of the
- 9:19greatest technical challenges in
- 9:21astronomy. The planet is completely lost
- 9:24in the glare of its host star.
- 9:26>> How bad is the glare?
- 9:28>> The star Proxima Centauri is about 10
- 9:31million times brighter than the light
- 9:33reflected by the planet. It's like
- 9:34trying to see a speck of dust on a flood
- 9:37light from a mile away. But a new
- 9:39instrument called Restredo is being
- 9:42built to do just that.
- 9:43>> Okay. So, how does Restredo pull off
- 9:46this magic trick?
- 9:47>> It's a combination of technologies. It's
- 9:49a spectrograph that will be installed on
- 9:51the very large telescope in Chile.
- 9:54First, it uses a coronagraph,
- 9:56essentially a tiny precise mask to
- 9:59physically block the light from the
- 10:00star. Then it uses a system of extreme
- 10:03adaptive optics with deformable mirrors
- 10:06to cancel out the blurring effect of
- 10:07Earth's atmosphere.
- 10:09>> And once the stars light is suppressed,
- 10:11what's the ultimate goal?
- 10:12>> The goal is to collect the faint light
- 10:15that has passed through or been
- 10:16reflected by the planet's atmosphere. By
- 10:18analyzing that light, Restredo can
- 10:21search for the chemical fingerprints of
- 10:23gases like oxygen, methane, or water
- 10:25vapor, potential bio signatures. It's
- 10:28one of our best chances yet to find out
- 10:30if the closest world beyond our solar
- 10:32system has an atmosphere and perhaps one
- 10:35that could support life.
- 10:36>> And that's a wrap on today's top
- 10:38stories. From new frontiers in human
- 10:40space flight to the cutting edge of
- 10:42exoplanet research, the universe never
- 10:45fails to amaze.
- 10:46>> It certainly doesn't. Thanks for tuning

- 10:51as we continue to explore the final
- 10:53frontier.
