S03E11: Starry Sojourns and Nuclear Dreams: Moon Bases and Black Hole Feasts

[00:00:00] Welcome to Astronomy Daily, The Podcast, your co-pilot on this interstellar voyage through the

[00:00:08] stars, planets and the black void beyond. You're tuned into the place where the vast

[00:00:13] expanse of space feels just a bit closer to home. So, fellow space enthusiasts prepare for

[00:00:20] liftoff. Fasten your seatbelts and let's dive headfirst into the cosmic news all around us.

[00:00:26] Join me as we chart a course through the latest developments in astronomy and space exploration.

[00:00:31] There won't be any light years between us and the universe as we bring the wonders of space

[00:00:36] right to your ears. Let's begin our journey across the cosmos. Here we go.

[00:00:46] After circling our planet for nearly 200 days, the international team aboard SpaceX

[00:00:52] crew 7 made their triumphant splashdown off the coast of Pensacola, Florida. Welcome back to Earth

[00:00:58] astronauts. This mission, under NASA's Commercial Crew Program, saw remarkable achievements forged in

[00:01:04] the microgravity far above us. Now let's paint a picture of this Odyssey. Picture four individuals from

[00:01:10] different corners of the earth. NASA's Jasmine Mogbelli, Esa's Andreas Mugansson, Jaxa's Satoshi Furukawa,

[00:01:18] and Roscosmos' Constantine Borosov. Together they've traveled an eye-watering 84 million miles,

[00:01:24] completing over 3,000 orbits around our home planet. Imagine watching sunrise and sunset 16 times a day.

[00:01:31] This was their life for 199 days. This mission was more than just a record long space flight.

[00:01:37] It became a beacon of international unity bringing together expertise from USA, Europe, Japan, and Russia.

[00:01:43] Their cooperative spirit didn't just keep them going, but also pushed the boundaries of what we

[00:01:48] thought was possible in space. Single spacewalks during this mission felt like small steps at the station,

[00:01:54] but were giant leaps in how we maintain our space outposts. And oh the science! These intrepid

[00:02:00] explorers didn't just gaze at the stars. They were hands-on with hundreds of experiments.

[00:02:05] Growing food in orbit? Check. Studying the human response to long-duration spaceflight? Check.

[00:02:12] Every bit of research on board was another crucial puzzle piece to our grand plans

[00:02:17] of establishing a human presence at the moon, Mars, and beyond.

[00:02:22] SpaceX's Dragon spacecraft, the sturdy vessel named Endurance, has completed its third mission,

[00:02:28] but it's not taking a break. After a pit stop at Cape Canaveral for a little TLC,

[00:02:33] Endurance will set off again, ever, the reliable space taxi. This safe return fires up the

[00:02:38] engines for NASA's Explorative Vision, reminding us that our species quest among the stars

[00:02:44] is a truly collaborative endeavor. As we embark on future journeys to new horizons,

[00:02:48] the Spirit of Crew 7 will continue to inspire, reminding us that when we unite, the universe unveils

[00:02:54] its wonders. In the cosmic wilderness, far from the comforting glow of our own Sun, an astronomical

[00:03:01] drama unfolds in the galaxy, NGC, 3,799, about 16 million light years away from Earth.

[00:03:10] The volatile spotlight centers on a supermassive black hole, a gravitational behemoth lurking

[00:03:15] at the heart of this distant galaxy. It's a scene of celestial catastrophe where a wandering star

[00:03:21] strayed too close to the black hole's clutches. What followed is both brutal and illuminating.

[00:03:27] A stellar feast, as the star is an exorably torn apart by the immense title forces.

[00:03:32] A process termed as a title disruption event. This cosmic phenomenon is akin to watching

[00:03:38] Mother Nature's own horror show, but through the chaos and destruction, it delivers valuable insights.

[00:03:44] Witnessing a star's death spiral into a black hole offers astronomers a rare opportunity

[00:03:49] to study these enigmatic giants whose whispers echo through the fabric of space-time

[00:03:54] and whose appetites shape the evolution of galaxies. The event, highlighted by an initial flare

[00:04:00] of brightness and a subsequent dimming, provides a real-life laboratory for us to observe the mechanics

[00:04:05] of black hole feasting. The doomed star's final moments send shockwaves of x-rays and light across

[00:04:11] the cosmos, a signal that triggers our telescopes and fuels our understanding. Each observation feeds

[00:04:18] a theory or hatches new questions about the nature of these dark space titans that straddle the line

[00:04:24] between the known and the unfathomable. Supernovas may be the common birth cries of stellar

[00:04:29] mass black holes. These smaller siblings of the supermassive variety are impressive,

[00:04:34] yet mere shadows of their gargantuan cousins that weigh millions to billions of times more than

[00:04:39] our sun. Supermassive black holes like the one in NGC 3799 are critical to the dynamics of galaxies.

[00:04:48] They are at once architects and destroyers and their origins are still cloaked in mystery.

[00:04:54] So what does it mean for us, the onlookers from a distant world when we see a star being dismantled

[00:04:58] piece by piece? It means we're one step closer to unlocking the growth patterns of black holes.

[00:05:04] This event observed as a SAS-23BD with its exceptional proximity and uniquely energetic profile

[00:05:12] could be a harbinger of newfound understanding. As researchers peer over the data,

[00:05:17] a narrative forms, painting a picture of a universe more dynamic and interconnected than

[00:05:22] we ever imagined. We must keep our telescopes trained and our minds open for these stellar feasts

[00:05:28] are not just distant spectacles, they're beacons that ignite the human spirit of inquiry,

[00:05:33] send our intellects chasing after the shadows and push the boundaries of what we dare to comprehend

[00:05:38] about the monstrous yet majestic rulers of the dark black holes. Picture this, an astronomical

[00:05:44] titan in the Chilean desert, a single dish stretching across 50 meters like a giant ear tuned

[00:05:49] to the whispers of the universe. Welcome to the vision of Atlast, the Atacama large aperture sub-millimeter

[00:05:55] telescope. A gigantic leap forward is proposed one where we could dissect the universe's most

[00:06:00] guarded secrets and radio waves. While we've marveled at arrays like Alma, their limitations have

[00:06:06] astronomers dreaming bigger. The collective urge now is for a single vast dish, a behemoth capable

[00:06:11] of picking up signals that inner woven setups can't focus on as sharply. A single large dish like

[00:06:17] Atlast could capture details with a precision and depth that we've only imagined. From the fingerprints

[00:06:24] of distant galaxies to the life story of individual molecules, all laid out in the dialect of radio

[00:06:30] frequencies. But why radio waves? You might ask. It's the language in which a lot of the universe's

[00:06:36] most intriguing information is transmitted, especially when it comes to the colder or more energetic

[00:06:41] corners of deep space. Current telescopes have limitations. Their smaller apertures drown in noise,

[00:06:48] obscuring the extreme features only larger single dishes can clearly unveil. Atlast would not

[00:06:54] just be any ordinary large aperture radio antenna. It's 50 meters single dish design promises a max

[00:06:59] field of view of two degrees, providing unprecedented mapping speeds for extensive cosmic phenomena,

[00:07:06] and whereas current large dishes give us tantalizing glimpses, Atlast aims to fling open the

[00:07:11] cosmic curtains wide, allowing us to peer at the peak of galaxies' spectral energy distributions,

[00:07:18] or the intricate contours of interstellar medium with newfound clarity. This proposal isn't just

[00:07:23] about technological bravado, it's a meticulous blueprint, a detailed plan oozing with the potential

[00:07:29] to affect a multitude of scientific endeavors. The hope is that at last could survey the entirety

[00:07:34] of our Milky Way, scrutinize proto-planetary discs and even chase down the elusive signatures

[00:07:40] of complex organic molecules, those cosmic breadcrumbs potentially leading us to the origins of life.

[00:07:45] And while the challenges are as steep as its proposed location, Atlast is an embodiment of the

[00:07:50] scientific community's ambition, a facility designed to endure, adaptable, and driven by renewable

[00:07:56] energy. A testament to our ever reaching quest to comprehend the great tapestry of the cosmos,

[00:08:02] as astronomers look ahead to potentially break ground by the end of this decade,

[00:08:06] the Atacama Desert might just become our window into the cosmos's grandest tales,

[00:08:11] a cathedral dedicated to the heavens where the universe's most ancient lights are finally untangled

[00:08:17] in the sub-millimeter range. In the cosmic dance of space discovery, Atlast is more than just

[00:08:23] a step, it's a daring leap. And for all of us who gaze upward, yearning to understand what's

[00:08:29] out there, it is quite literally a vision for the future. Roscosmos and CNSA are leaping forward

[00:08:36] with an audacious vision that could light up lunar exploration in ways we've never seen before.

[00:08:41] They're talking nuclear, a nuclear reactor to be precise on the surface of the moon.

[00:08:47] Their goal? To energize a lunar base, turning it into a hub of scientific activity and cosmic

[00:08:52] discovery, and they've set their deadline for 2035. This shared lunar base with the potent name

[00:08:59] of the International Lunar Research Station introduces a bold new chapter in International Space

[00:09:05] Collaboration. It isn't just a sign of ambition, it's a declaration of the continued human urge to

[00:09:11] push into new frontiers. The base, once conjured into reality, will stand as a testament to human

[00:09:18] ingenuity. A beacon on the moonlit landscape that says, here we are and here we stay.

[00:09:24] But setting up shop on the moon isn't like flipping the switch on your home power grid.

[00:09:29] Traditional energy sources fall short in the harsh cold silence of space.

[00:09:34] That's where the nuclear reactor comes in, promising to deliver a steady and reliable

[00:09:38] power source vital for the sustenance of lunar bases. Think about it, no looming shadows or

[00:09:45] long nights will dim the lights of the ILRS as this reactor could turn out power continuously

[00:09:50] supporting life and science far from our blue home. It's not just about keeping the lights on,

[00:09:56] this nuclear reactor is envisioned to be fully automated. Picture this, machines building

[00:10:02] and managing a powerhouse on another world, a scenario plucked from science fiction becoming science

[00:10:07] fact. The technologies needed for this task are reportedly nearing readiness and that's huge.

[00:10:12] It implies a leap in our robotic capabilities hinting at a future where humans and machines

[00:10:17] tackle the cosmos hand in robotic hand. And before you ask, no, NASA astronauts likely won't be

[00:10:24] swinging by. Political tides on Earth ebb and flow and right now they're drawing clear

[00:10:29] distinctions in the lunar dust. Nevertheless, this project between Russia and China invites us to

[00:10:35] dream of what's to come. Lunar bases humming with the silent song of nuclear power, propelling humanity

[00:10:42] into a future as boundless as the night sky. The space launch system or SLS for intimits,

[00:10:48] NASA's behemoth rocket meant to escort humans beyond Earth's stratosphere and onwards to the moon

[00:10:54] is evolving. Just picture a caterpillar unfolding into a lunar soaring butterfly.

[00:11:00] This isn't just any butterfly though, it's the SLS block 1B, the upgraded sibling in the SLS

[00:11:06] family and it means serious celestial business. Imagine the SLS block 1, the beast that propelled

[00:11:12] Artemis 1 into the firmament now amplify that vision. SLS block 1B is set to make its grand

[00:11:18] debut with Artemis 4, boasting beefier configurations to shuttles us further and faster into space's vast

[00:11:24] frontier. It's a clear statement. NASA's not just dabbling in lunar visits, it's crafting a highway

[00:11:30] of rockets designed for consistent ambitious moonshots. John Honeycutt, the SLS program manager,

[00:11:37] has put it plainly, accentuating how SLS was congenitally faded to morph into heftier versions.

[00:11:44] Capable of launching more audacious missions to not only the moon but the far reaches of our solar system,

[00:11:50] their blueprint's been clear, start strong then reach for the cosmic shores built upon the triumphs

[00:11:56] of their Artemis predecessors. And gather round tech enthusiasts because we're not just talking

[00:12:01] brawn but brains too. The block 1B's brainy boost comes from the exploration upper stage or EUS,

[00:12:08] loaded with four engines replacing the interim ICPS's solitary one. This is the celestial locomotive

[00:12:14] expected to keep us chugging along for the first eight hours post launch. That's like comparing an

[00:12:19] energetic sprint to a marathon, the stakes just got higher and when you peer into SLS block 1B's toolkit

[00:12:26] you'll find a universal stage adapter bigger than a city apartment to fit payloads. Dream bigger

[00:12:32] think gateway modules for an orbital lunar outpost. It's a clarion call back ining to the days of

[00:12:37] building in moon orbit, gear by gear creating layovers for astronauts on route to lunar surfaces.

[00:12:43] Payloads those precious cargoes of lunar dreams get a hefty heave ho too, soaring from 59,000 pounds

[00:12:50] to a whopping 84,000 pounds. That's equivalent to hoisting more than six adult African elephants

[00:12:57] straight out of Earth's gravitational embrace. Here's the cosmic cherry on top, flexibility. SLS block

[00:13:04] 1B ensures we've got windows wide enough to seize launch opportunities twice daily. We're talking

[00:13:09] about a logistics revolution, a streamlined path to orbit and joy rides to the moon dance with more

[00:13:14] grace and less weight. The vision NASA is casting before us is clear as starlight. This agency is

[00:13:20] not just stepping on the gas, it's charting paths, constructing ladders and highways among the stars,

[00:13:26] set to land the next echelons of intrepid explorers upon our cratered neighbor. So when we think of NASA's

[00:13:32] Artemis expansion, it's more than a rocket. It's the heartbeat of a program, a pulsing symphony of

[00:13:37] science exploration and human aspiration. With SLS block 1B's powerful allure, NASA is pushing us to

[00:13:44] ride the fiery chariot, carving a trail that solidifies humanity's place amidst the timeless

[00:13:49] waltz of the cosmos. And just like that, our cosmic journey together across the expansive space wraps

[00:13:54] up. But fret not fellow stargazers for our shared curiosity is a star that never burns out.
