Gentry Lee spent nearly five decades at NASA's Jet Propulsion Laboratory, and in that time he helped shape some of the most ambitious missions in the history of space exploration. A new documentary, “Starman,” chronicles his career and the big question that runs through it: is there life beyond Earth? Lee worked on every NASA mission to land on Mars, helped Carl Sagan bring the Universe to living rooms around the world with “Cosmos,” and oversaw dozens of active missions as Chief Engineer for the Solar System Exploration Directorate at JPL. Few people have had a front-row seat to the Space Age quite like him. In this episode, host Sarah Al-Ahmed sits down with Gentry at Planetary Society headquarters just one day after his retirement from JPL. He reflects on the colleagues who shaped him, the missions that changed our understanding of the Solar System, and why the search for life beyond Earth remains the most profound endeavor humanity has ever undertaken.

It's still time for another BIG and BRILLIANT adventure into the world of science on this week’s Science Quest! In Science in the News, NASA is rethinking its plans for landing astronauts on the Moon, scientists believe the history of writing might be thousands of years older than we once thought, and Frederick Wilkinson from Queen Mary University of London explains why a recent boom in sea turtle numbers might not be quite as good news as it sounds. It’s time for your questions too. Akiva wants to know why your tummy gets smaller when you breathe in, and John Bridges from Leicester University answers Nicolas' question: How are asteroids made? Dangerous Dan introduces us to something a little different this week: the super-Earth exoplanet TOI-1452b, a strange and fascinating world far beyond our Solar System. Then in Battle of the Sciences, Mark Grabowski from Liverpool John Moores University steps into the ring to make the case for palaeoanthropology, the science that studies ancient humans and our evolutionary ancestors. Plus, Harry and Terry stumble across the asteroid belt in this week’s Space Cadets adventure as they continue their accidental journey through space. What do we learn about? How asteroids form in space Why NASA is changing its plans for Moon missions Why the history of writing might be older than we thought Why a sea turtle population boom may not be entirely good news What happens to your body when you breathe in The strange super-Earth exoplanet TOI-1452b How scientists study ancient humans and our ancestors All that and more on this week’s Science Quest!Join Fun Kids Podcasts+: https://funkidslive.com/plusSee omnystudio.com/listener for privacy information.

A key question about the early history of the Solar System is whether the giant planets formed roughly at the distances from the Sun they presently occupy, or, as some theories predict, much closer to the Sun. The discovery of other solar systems with radically different configurations of planets has made this question more pressing, since it appears that the configuration of the Solar System might be atypical. In the podcast, Hal Levison explains why the Trojan asteroids of Jupiter offer us the best opportunity to discriminate between the various models of Solar System evolution. And that is why a spacecraft called Lucy is now well on its way to a rendezvous with these asteroids. Hal Levison is the Principal Investigator of the Lucy mission. He studies the dynamics of astronomical objects and, in particular, the formation and long-term behavior of solar system bodies. He is one of the original proponents of the Nice model (named after the city where it was conceived), a scenario that proposes the migration of the giant planets from an initial compact configuration closer to the Sun to their present positions. He is Chief Scientist in the Department of Space Sciences at the Southwest Research Institute in Boulder, Colorado.

Astronomers may have found the missing link in the story of the Milky Way's most common planets. In this SETI Live, host Moiya McTier is joined by exoplanet scientist John H. Livingston to explore a new discovery that helps connect the dots between small rocky worlds like Earth and the larger "sub-Neptunes" that dominate our galaxy. Using cutting-edge observations and statistical analysis, researchers have identified a population of planets that appears to bridge a long-standing gap in our understanding of planetary formation. For years, astronomers have known that planets of sizes between Earth and Neptune are incredibly common—but their origins and evolutionary paths have remained puzzling. This new result may finally clarify how these worlds form, evolve, and sometimes transform. What does this mean for: • How do planetary systems assemble? • Why does our Solar System look so unusual? • The search for habitable worlds beyond Earth? Join us as we break down the science, the methods, and the bigger implications for exoplanet research and the search for life.

fWotD Episode 3223: Galaxy Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles.The featured article for Monday, 2 March 2026, is Galaxy.A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. The word is derived from the Greek galaxias (γαλαξίας), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a thousand stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's centre of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.Galaxies are categorised according to their visual morphology as elliptical, spiral, or irregular. The Milky Way is an example of a spiral galaxy. In addition to shape, galaxies may be notable due to special properties, such as interacting with another galaxy, producing stars at an unusual rate, or having an active galactic nucleus. It is estimated that there are between 200 billion (2×1011) and 2 trillion galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances in the order of millions of parsecs (or megaparsecs). For comparison, the Milky Way has a diameter of at least 26,800 parsecs (87,400 ly). Its nearest large neighbour, the Andromeda Galaxy, is just over 750,000 parsecs (2.4 million ly) away.Most galaxies are gravitationally organised into groups, clusters and superclusters. The Milky Way is part of the Local Group, which it dominates along with the Andromeda Galaxy. The group is part of the Virgo Supercluster. At the largest scale, these associations are generally arranged into sheets and filaments surrounded by immense voids. While there are good models describing the formation of stars from gravitational condensation of dense clouds of gas, galaxy formation is less well understood. The process operates on the scale of a billion years. Galaxies occasionally collide during their lifetime.This recording reflects the Wikipedia text as of 01:31 UTC on Monday, 2 March 2026.For the full current version of the article, see Galaxy on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Mastodon at @wikioftheday@masto.ai.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm generative Matthew.

But the concept never truly disappears, and for good reason. Near-Earth asteroids, numbering in the millions, contain staggering quantities of precious metals, rare earth elements, and water ice. Ironically, those same materials — iron, gold, platinum, nickel, and dozens of others — were originally delivered to Earth by asteroids during the Late Heavy Bombardment period some four billion years ago. We're essentially talking about going back to the source. The three main asteroid types — carbonaceous (C-type), silicate (S-type), and metallic (M-type) — each offer distinct resources. Beyond metals, the abundance of water ice in the solar system could relieve pressure on Earth's increasingly stressed freshwater supply and fuel deep-space missions. Philosophically, the implications are profound. Thomas More and Nietzsche both wrestled with why scarcity drives human value systems. Flood the market with space-borne metals and the entire economic architecture built on scarcity begins to crumble. Orwell saw it too — abundance erodes hierarchy. The first trillionaires born from asteroid mining might find their wealth meaningless almost immediately after making it. But the darker scenarios deserve equal attention. Redistributing consumption off-world doesn't eliminate it. Space debris, environmental degradation beyond Earth, and the very real risk of exploitative labor structures in off-world operations — echoes of colonialism and indentured servitude — are not science fiction. They're logical extensions of human patterns. The enthusiasm may ebb and flow, but asteroid mining remains an inevitable chapter in humanity's story. The real question is what kind of story we choose to write around it. ______________________ Resources   ______________________ For more podcast Stories from Space with Matthew S Williams, visit: https://itspmagazine.com/stories-from-space-podcast Hosted by Simplecast, an AdsWizz company.

Could a single ancient impact have briefly transformed one of the Solar System’s darkest moons into a cryovolcanic world? When Voyager 2 flew past Uranus in 1986, it captured the only close-up images we have of Umbriel, a heavily cratered, charcoal-dark satellite long considered geologically inactive. But one feature stands out: a bright ring inside the 131-kilometer-wide Wunda crater. In this episode, Sarah Al-Ahmed speaks with Adeene Denton, NASA postdoctoral program fellow at the Southwest Research Institute, about her team’s new study published in the Journal of Geophysical Research: Planets. Using shock physics simulations, Denton and her colleagues reconstruct the impact that formed Wunda crater to determine what Umbriel’s interior must have been like at the time. Their modeling explores whether impact-induced cryovolcanism can explain the bright deposits observed on the crater floor. Then, in What’s Up, Bruce Betts, chief scientist of The Planetary Society, joins Sarah to break down one of the key mechanisms that keeps icy moons from freezing solid, tidal heating driven by orbital resonance.

As critical infrastructure becomes an increasing target in both conventional and cyber warfare, countries are reassessing how vulnerable their national power grids really are. In tiny Israel the vulnerability is even more acute and the push for renewable energy is no longer just an environmental issue but a national security priority. Danny Denan, the CEO of GreenTops, told reporter Arieh O’Sullivan that more needs to be done to expand rooftop solar systems to reduce the risk of large scale blackouts during crises.

MIT physicist David Kaiser is one of those rare scientists who can make mind-bending physics feel like a great conversation over coffee — funny, generous, and genuinely thrilled by what we still don't know. And what he's working on is wild. What the if the universe is packed with invisible black holes smaller than an atom? Dave thinks the mysterious "missing stuff" that holds galaxies together might not be some exotic undiscovered particle — it could be tiny black holes that formed a split second after the Big Bang. If he's right, a handful of them could be cruising through our solar system right now, and we might be able to catch one in the act just by watching Mars wobble. We also dig into whether a rogue black hole might have flattened a Siberian forest in 1908, and rest assured, the residents of Brooklyn have nothing to worry about.

This show has been flagged as Clean by the host. This is a further look at the stories of the First Doctor, portrayed by William Hartnell, during the 1960s. The First Doctor, Part 4 Galaxy 4 This science fiction story is focused on the idea of not judging a book by its cover. The Tardis lands on a deserted, dying planet. They see a funny looking robot that Vicki calls a “Chumbley”. Then another one appears, and they investigate, but are rescued by three beautiful women who tell them they were in great danger, and take the three travelers back to their ship, where they meet the leader, Maaga, another beautiful woman. But somehow these women are odd and cold. They tell of how they met another ship from a evil race, the Rill, and that in a space battle the ships damaged each other and landed on this planet. Then later the travelers meet the Rill, who initially refuse to reveal their appearance because it would frighten the humans. Turns out they were very alien in appearance, but not at all evil, and it was the beautiful women who were evil. Mission to the Unknown This short little story takes place on the planet Kembel, and agents from Earth realize that the Daleks are here, and up to no good. This is really a prequel to The Daleks' Master Plan, and is notable as the only Doctor Who story in which none of the regular cast appears. The reason is that this is an extra episode slot given to the Doctor Who team late in the day, and the regular cast were already given vacation time off. So it is best to take this as Episode 0 of The Dalek's Master Plan, not as a stand-alone story. The original story has been lost, like so many episodes of early Doctor Who, but a very nice version was done by the University of Central Lancashire, and you can view it on YouTube. It is introduced by Edward de Souza, who played Marc Cory in the original, and is worth a look. They really did a good job. The Myth Makers This is another “historical” story, though instead of verified history it is historical legends at play here, in the form of the Seige of Troy by the Greeks. So you have all of the Homeric cast here: Achilles, Priam, Hector, Odysseus. The Doctor is taken for a God by Achilles, though Odysseus has his doubts. Vicki is captured by the Trojans and taken to Troy, calls herself Cressida, and is taken for a Goddess. Steven goes to Troy to try and free her, but is seen as a Greek, and so Vicki is now suspect. She falls in love with a son of Priam named Troilus, and you think something might happen here, particularly if you are familiar with play of Shakespeare called Troilus and Cressida. This story only has faint echoes of the play, preserving that Cressida is Greek and Troilus is Trojan. In this case it is Cressida staying with Troilus, so instead going back to the Tardis Vicki is now out. One more companion gone. This marked the departure of Verity Lambert as producer, and she was replaced by John Wiles. Wiles tried to implement changes, such as making the show a bit darker, but ran into opposition from both Hartnell and BBC Management, and resigned after producing four stories ( The Myth Makers through The Ark). And the popularity of other SF shows on television made a move to more SF and less history desirable. And as for Hartnell's opposition, it is notable that he had become quite identified with the role of The Doctor and was very proprietorial with it. This would come to pose problems later as his health declined. The Daleks' Master Plan This story arc takes twelve episodes, or thirteen if you add Mission to the Unknown, as you indeed should. The reason for such a long story arc is that Sir Huw Wheldon, the Director-General of the BBC at that time wanted a “monster length” Dalek story because his mother was a big Dalek fan. And this story has a lot going for it. The length means that you can do more character development. The story starts out with Steven recovering from a sword-thrust during the fall of Troy, and being attended by Katarina, a Trojan maiden, who is now in the Tardis. They arrive on the planet Kembel, and meet with Space Special Security agent Bret Vyon, played by Nicholas Courtney, who in a few years would become the beloved Brigadier Lethbridge-Stewart. Vyon tries to force the Doctor to take him to Earth so he can warn the planet, but the Doctor recognizes the Daleks and wants to find out more about their plans. And this brings us to one the most evil villains in Doctor Who, Mavic Chen. You see, the Daleks have assembled a group of villainous aliens to join together in conquering the Earth, and Mavic Chen is part of the group. He is also the idolized Guardian of the Solar System. So he is a traitor! Katarina, the Trojan maiden, sacrifices herself to save the others from a convict they meet on a prison planet. Another wonderful character is Sara Kingdom (played by Peggy Marsh), head of Space Special Security, who has been told by Mavic Chen that Vyon and the others are traitors, and who kills Vyon, who is in fact her brother! But they manage to convince her that Chen is the real traitor, and she joins them. In the middle of this story arc Christmas happened, and this resulted in the most absurd episode ever of Doctor Who, called The Feast of Steven, capped by the Doctor breaking the fourth wall. The episode is now among the missing. but you can find reconstructions on YouTube if you want to see the absurdity of it. And there is a re-appearance of The Meddling Monk. This is a sprawling story, but overall worth a look. Mavic Chen, played by Kevin Stoney, is delightfully evil, and Stoney would return to play another villain in the Troughton story The Invasion. and it is interesting to see Nicholas Courtney before he got the role he would always be identified with. Doctor Who would not do anything this large again until _The Flux_ in 2021, and frankly this story makes more sense. The Massacre of St. Bartholomew's Eve You will often see this as simply The Massacre, which is fine since there is no other story with a similar title. And after that massive science fiction story, another historical story. This involves the true story of Protestants in France being massacred by the Catholics, and the main feature worth calling our here is that William Hartnell plays two roles in this story. He is the Doctor, of course, but also the Abbott of Amboise, a leader among the Catholics looking to rid France of the Protestants. This idea of playing two parts became even more nicely done by Patrick Troughton later in Enemy of the World. In any case, this leads to confusion by Steven who thinks the Abbott is actually the Doctor. In the story a servant girl named Anna Chaplette is rescued, and this opens up the interesting possibility that she is the ancestor of Dodo (i.e. Dorothea) Chaplet, a companion who appears at the end. She witnesses a car crash, and barges into the Tardis thinking she can call the police. While the novelty of Hartnell playing two parts may stand out on first look, this story is really a showcase for Peter Purves, in his role of Steven Taylor. Because Hartnell is not on screen very much, Purves really has to carry the plot, and does so admirably. Hartnell was on vacation when the second episode was filmed, and so didn't appear at all. And his health problems were beginning cause problems which contributed to this situation. He was having a lot of trouble with remembering his lines, which is a real problem for an actor. He was not that old by current standards, as he was 58 when this story was produced, and as I am 73 as I write this, 58 seems more like late youth to me. The Ark The Tardis materializes on a spaceship in the far future. It is carrying the future of the human race to a new planet, Refusis 2, because the Earth is falling into the sun. But it also has an odd race called the Monoids, who have one eye. They are an alien race who came to Earth when their own planet was dying, and now they serve the humans. Unfortunately, the Tardis crew carries germs for which humans and Monoids on the Ark have no immunity, and sickness breaks out. One faction wants to kill the Doctor and his companions, but instead the Doctor finds a cure for the disease, and they leave on the Tardis. Then the Tardis materializes back on the Ark, but they discover that hundreds of years have passed. The Monoids have rebelled and taken over, and now the humans serve them. As the old saying has it, be kind to those you meet on the way up, for you will meet them again on the way down.

Caroline Smith is passionate about space rocks, whether they're samples collected from the surface of asteroids and the Moon and hopefully Mars one day soon, or meteorites, those alien rock fragments that have survived their fiery descents through our atmosphere to land here on Earth. She is Head of Collections and Principal Curator of Meteorites at the Natural History Museum, home to one of the finest meteorite collections in the world. Her interest in rocks began while wandering the foothills of the Rocky Mountains, as a child, picking up the ones that caught her eye and bashing them with a hammer, hoping to find treasure inside, whether it's gold, diamonds or dinosaur fossils. Her work today, studying rocks that have landed here on Earth or those still out there in space, is no less ambitious. She analyses their chemical composition looking for tantalising clues that might reveal how our Solar System formed, and potentially the presence of the chemical building blocks necessary for life itself.

We often think of our planet as an isolated island, solitary and cut off from the cosmic ocean it resides in. But the truth is, Earth is intimately connected with the Universe surrounding it. What's more, by learning more about the Solar System around us, humanity has changed its own view of the world as well. Dr Dagomar Degroot from Georgetown University spoke to us to explore this idea in more detail. Learn more about your ad choices. Visit podcastchoices.com/adchoices

For the past year, we've been exploring The Story of Creation — human origins, universal origins, and the deeper truth of existence itself. In Part 105, Michelle Vickers introduces Gaia (Mother Earth) and Pan as universal intelligences that help us understand how reality actually forms — not as something solid and static, but as an evolving energetic experience. If you've ever questioned: • Is reality fixed? • Is Earth a static planet? • Do we choose our life experiences? • Is manifestation real? • What is the relationship between intention and physical experience? • Is time and space real? This episode goes deep into the mechanics of existence. Pan explains: • How intention becomes energy, and energy becomes experience • Why physical representation is not inside time and space • How humanity collectively created the illusion of solidity • Why science defines reality as static — and why that limits consciousness • How universal existence is in constant motion • Why storms, earth shifts, and environmental changes reflect rising consciousness • Why the only thing that is truly real is energy Michelle also shares a guided energetic practice to: • Reignite your connection with Earth • Activate your soul frequency • Restore energetic current between you, humanity, and universal existence • Break attachment to the illusion of solidity You are not a human moving through a solid world. You are a universal being participating in an evolving energetic experience. And your mission is not survival — it is expansion. This is Episode 181, Part 105 of The Story of Creation — where we return to our universal heritage and remember that: You are existence, and existence is you. 0:00 – Why Understanding Human Origins Changes Your Self-Worth 0:58 – Why Humanity Gave Universal Beings Different Names (Religion & Culture Explained) 2:28 – Who Is Pan?

https://www.youtube.com/watch?v=-Alz4UXGqLk From March 8, 2017. In just a few months, NASA's Cassini spacecraft is going to die, crashing into the planet Saturn. Let's look back across the mission's history. What were the highlights? What did we learn?   Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com   Ask me my favorite object in the Solar System, especially to see through a telescope, and my answer is always the same: Saturn. Saturn is this crazy, ringed world, different than any other place we've ever seen. And in a small telescope, you can really see the ball of the planet - you can see its rings.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Where did Earth’s water come from? In this episode of Planetary Radio, we explore how scientists are answering that question by studying a remarkably well-preserved record of the early Solar System: lunar samples brought back by the Apollo missions. Host Sarah Al-Ahmed is joined by Tony Gargano, postdoctoral fellow at the Lunar and Planetary Institute with the University Space Research Association and a research affiliate at NASA’s Johnson Space Center. Gargano studies lunar rocks and regolith to understand how planets form, evolve, and acquire key ingredients like water over time. By analyzing subtle chemical fingerprints preserved in Apollo-era lunar regolith, his work helps constrain how much water meteorites could have brought to Earth and what that means for our planet’s path to habitability. The episode also features a short bonus segment with actor George Takei, recorded at the Academy Museum of Motion Pictures during a screening of “Star Trek IV: The Voyage Home.” Takei reflects on the enduring legacy of “Star Trek,” its influence on generations of scientists and explorers, and why he is excited about humanity’s return to the Moon in the Artemis era. He connects science fiction’s hopeful vision of the future with the real science helping us understand our origins today.

The Space Show Present Dr. Greg Autry, Tuesday, Feb. 3, 2026Quick Summary: The group explored various aspects of the Artemis program, including its challenges, timeline concerns, and comparison with China's space efforts, while discussing the importance of maintaining U.S. leadership in space exploration. The conversation concluded with discussions about space policy, commercial space activities, and educational challenges facing the U.S., with emphasis on the need to generate public enthusiasm for space exploration initiatives.Detailed SummaryDavid introduced Dr. Greg Autry, a space policy expert and economics professor at UCF, to discuss his work and recent developments in space exploration. They touched on the Artemis II mission, commercial space launches in Florida, and concerns about the U.S. moon landing timeline. Greg expresses skepticism about the political commitment to space exploration under potential new leadership, noting that candidates like Vance and Harris may not prioritize space initiatives. The conversation concludes with a brief overview of Greg's background and upcoming programs at UCF.Dr. Autry discussed his role at the University of Central Florida, where he helped launch the world's first space MBA program in collaboration with Professor Zahir Ali. He highlighted the program's space-relevant curriculum, notable faculty, and upcoming guest speakers, including Pam Melroy and Jim Bridenstine. Autry also introduced the Space Ideation Challenge, a competition offering $125,000 in prize money for innovative space policy ideas. Greg also mentioned the delay of the Artemis launch due to cold weather affecting the hydrogen seals. He expressed pride in contributing to the decision to return to the moon in 2016 and shared his thoughts on the public's perception of the Artemis program.Our Wisdom Team group discussed the challenges and potential of the Artemis program, particularly focusing on the Starship mission and the complexities involved. They expressed concerns about the timeline for meeting 2028 deadlines, given the complexity of the technology and the need for political appointments. Despite these challenges, Greg expressed optimism about Administrator Jared Isaacman's leadership and the potential for a sustainable and permanent presence on the moon. Greg also compared the U.S. approach to the moon with China's simpler program, viewing the U.S. effort as a more ambitious but worthwhile endeavor.Our team discussed the Artemis program and space exploration strategy, with Phil sharing insights from a space historian's video that criticized NASA's approach as being too focused on quick wins rather than long-term scientific objectives. Greg noted that Americans typically prefer a “poker” approach to waiting for lucky breaks rather than the Chinese “Go” style of careful long-term planning, but emphasized that the Orion capsule and Space Launch System have been under development since 2003 and 2010 respectively, with continuity through multiple administrations. The discussion concluded with Marshall raising questions about launch facility readiness, which Autry addressed by explaining that the United States has three human-rated launch pads, with facilities at Cape Canaveral and the Space Force side being prepared for Starship launches.Our team discussed the need for infrastructure and base building on the moon, with Ajay emphasizing the importance of starting construction to save face for the Trump administration and prevent future program cancellations. Autry noted that while Artemis II will be significant, they need to generate public enthusiasm. Ajay proposed using Falcon Heavy to transport 14 tons of payload to the moon's surface. David questioned the likelihood of private companies alone achieving these goals, to which Greg responded that while private companies could theoretically fund it, they might be reluctant to make donations to a government program.The group discussed space policy and commercial space activities, with Dr. Greg Autry emphasizing that NASA's Artemis program should continue while exploring additional initiatives like Ajay's proposed lunar lander concept, which Autry suggested could be an addition rather than replacement for existing programs. The discussion covered concerns about China's space program and the importance of maintaining U.S. leadership in space, with Autry noting that completing the Artemis moon program is crucial to avoid having China claim superiority over the U.S. The conversation also touched on educational challenges facing the U.S. and the need to better prepare students for science and engineering careers, while David highlighted growing public interest in space science among younger generations.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223 (Not in service at this time)For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

The Space Show Presents Mark Whittington, Sunday, Feb. 1, 2026Quick Summary:Our program began with followed by conversations about the Artemis II mission and space technology advancements. The group explored various aspects of space exploration, including Iran's space program, lunar missions, and the development of space suits and launch systems. The discussion concluded with conversations about AI in journalism, nuclear reactor technologies, and the upcoming Artemis II mission, including its potential for public celebration and media coverage.Detailed SummaryOur Zoom program Wisdom Team discussed the Artemis II mission, with Mark expressing confidence in its success. They also talked about the challenges of keeping up with rapidly advancing technology and the stock market, particularly in the space industry. David expressed interest in doing a show about space-related ETFs but felt that Andrew, who focuses on his own ETF, might not be the best person for it given there now a plethora of space focused ETFs.After introducing Mark Whittington as the guest for the Sunday space show, we discussed Iran's space program. Mark explained that while Iran's space program is not robust by global standards, it serves dual purposes, potentially threatening global security. He suggested that if Iran were to transition to a more freedom-oriented regime, preserving and developing their space program could be beneficial for economic growth and inspiring young Iranians to pursue STEM subjects.Mark continued talking about Iran's space program, highlighting its development of launch vehicles and satellites, and its potential to support a nuclear program. He suggested that a post-Islamic Republic Iran could benefit economically from continuing its space program and joining international initiatives like the Artemis Accords. David inquired about the U.S. government's perspective on Iran's space program, and Mark noted that concerns primarily focus on its nuclear capabilities. They briefly touched on the potential for military action against Iranian spaceports and the possibility of Reza Pahlavi returning as a stabilizing figure in Iran. The conversation concluded with a brief mention of the upcoming Artemis II mission.Mark discussed the Artemis II mission in some detail, addressing concerns about the heat shield and NASA's confidence in its workarounds. He highlighted the mission's potential impact on American society, comparing media coverage then and now, and expressed hope that Artemis II would be a significant story. Mark also noted the mission's duration of 10 days, including a loop around the moon, and emphasized the diversity of the crew. David shared a question from a listener about potential lunar payload or surface interaction during Artemis II, which Mark clarified does not involve landing on the moon but rather a loop around it.We continued focusing on the Artemis program and lunar exploration. Mark explained that CubeSats will launch with Orion but won't be lunar landers, and SpaceX and Blue Origin are developing lunar landers. The next Starship test is expected in 5 weeks, aiming to refuel in low Earth orbit and land on the moon. John Jossy inquired about ESA's life support system test, which Mark confirmed is part of the systems test in low Earth orbit. Marshall asked about reusability of the Space Launch System's solid rocket boosters, to which Mark replied they are not planned to be reusable due to the infrequent use of the system.Our team discussed public excitement and historical significance of the Artemis II mission, with Mark noting that while Artemis II should be the story of the year, public awareness and support may be lower than during the Apollo missions. They discussed the upcoming Starship test in 5 weeks as a potential rival for public attention, and explored the possibility of live TV coverage during the mission, including the crew's perspective of Earth rise. Mark suggested that the crew should be allowed to express their personal thoughts and experiences during the mission rather than following a pre-determined script.Our team also discussed the inspirational impact of Earthrise, with Marshall sharing his perspective on the spiritual connection to celestial objects. Mark and Marshall exchanged views on the role of mathematics and physics in understanding the universe, while David inquired about public perceptions of space exploration versus Earth's economic concerns. Mark highlighted the potential economic benefits of space travel and SpaceX's upcoming IPO, as well as Elon Musk's plans for AI data centers in orbit, powered by a network of satellites. The conversation concluded with a discussion on the development of space-based solar power and its potential to overcome the limitations of solar energy on Earth, with our guest emphasizing the importance of diverse energy sources like nuclear and natural gas.Mark discussed the development of lunar spacesuits, noting that Axiom Space is the prime contractor and progress is ongoing, with suits expected to be ready by 2028. He also addressed the potential merger between SpaceX and Tesla, suggesting it would create a holding company with separate divisions, and discussed the development of Optimus robots for space exploration. Mark highlighted the success of NASA Administrator Bill Nelson, who was confirmed after a tumultuous process, and expressed optimism about Artemis II's upcoming launch and its potential to generate momentum for future space missions. He also touched on the challenges of transitioning from SLS to commercial systems for future Artemis missions, noting that while there are concerns about delays, the goal remains to build a lunar base.Our group discussed historical SpaceX launch operations, particularly focusing on the Falcon 1 rocket launches from Kwajalein Atoll in the Pacific. David explained that while Kwajalein offered advantages like reduced orbital velocity requirements due to its equatorial location, the 8,000-mile supply line and classified military operations at the site ultimately led SpaceX to shift operations to other locations including Vandenberg and Boca Chica. The discussion concluded with Marshall recalling the Celestas Memorial payload incident, where a Falcon 1 rocket failed to reach orbit and instead crashed into the Marianas Trench, though the exact crash location was never publicly disclosed by SpaceX.John Hunt proposed a fallback plan for Starship's on-orbit refueling, involving an unmanned variant with an exploration upper stage as a third stage, to reduce costs for lunar missions. Mark and David discussed the potential of nuclear power and propulsion in space, as well as the integration of such technologies into Starship for Mars missions. David emphasized the importance of having a plan for implementing new ideas, cautioning against presenting alternatives without a clear path forward. The conversation also touched on the role of AI in managing information overload for executives like Elon Musk, with Marshall sharing insights from his experience with AI in research and business.Mark described the limitations and potential of AI in journalism, emphasizing the need for human oversight in verifying sources. Ajay shared information about advanced nuclear reactor technologies, including Generation 4 reactors and molten salt reactors, highlighting their safety features and reduced waste production. Mark expressed interest in learning more about these reactors. The group agreed to continue the discussion if time permitted, with Mark mentioning his upcoming focus on the Artemis II mission and other space-related stories.Mark continued promoting the upcoming Artemis II mission, which is scheduled for a wet dress rehearsal followed by a potential launch on February 8th, after the Super Bowl. He shared his experience as a space writer and author, mentioning his books about lunar exploration. The group discussed the potential for a ticker tape parade and public celebration if the mission is successful, with Mark agreeing to write about this possibility in his Sunday newsletter. Dr. Ajay and others expressed interest in subscribing to Mark's newsletter, which is distributed through The Hill newspaper. David did not think a ticker tape parade was in the cards, so to speak.Special thanks to our sponsors:American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223 (Not in service at this time)For real time program participation, email Dr. Space at: drspace@thespaceshow.com for instructions and access.The Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.

What if Europa’s seafloor isn’t alive with activity after all? This week on Planetary Radio, host and producer Sarah Al-Ahmed explores new research that reframes how scientists think about one of the Solar System’s most intriguing ocean worlds. Sarah is joined by Paul Byrne, associate professor of earth, environmental, and planetary sciences at Washington University in St. Louis. Paul is the lead author of a new study suggesting that the seafloor beneath Europa’s global ocean may be geologically quiet today, potentially lacking the hydrothermal activity often associated with habitable environments on Earth. Together, they discuss how scientists investigate places we can’t yet observe directly and why Europa remains a compelling world to explore regardless of what we find. Then, Bruce Betts, chief scientist of The Planetary Society, joins us for What’s Up to explain why Saturn’s moon Enceladus shows strong evidence for active hydrothermal vents beneath its icy crust, offering a fascinating contrast between two ocean worlds.

The Sun is an unrelenting nuclear inferno. Mercury is a dense little rock with zero atmosphere and the worst sunburn in the system. Venus is a cautionary tale wrapped in sulfuric acid clouds, spinning in the wrong direction just to be difficult. And Mars is a frozen desert haunted by the ghost of ancient oceans. In this episode, Shane and Duncan dig into the bizarre and extreme nature of the inner planets, unpacking strange rotations, impossible temperatures, missing magnetic fields, and Martian cliffs that make the Grand Canyon look like a pothole. Nothing in the inner solar system is normal, and it only gets weirder from here. ~ Support the show by becoming a Midnight Minion, Menace, or Maniac, and unlock exclusive bonus content over at PATREON ~ Join the MFFI community and vote on episode topics via DISCORD ~ I Join the Midnight Masses!

The Paranormal Peep Show with Ben Emlyn-Jones Jan 2026.Is the strange comet passing through our Solar System just a comet or is it something more alien? Certainly it has many differences to other comets, but this one is not from our solar neck of the woods, but from deep in our own Milly Way galaxy. It has performed strange movements, given off strange gasses, has a tail in the opposite direction to what it should be, it arrived almost level on the plane of our own solar system planets. Could it be a craft? Is it some kind of remote probe about to drop off smaller craft or transmit signals to Earth?Regular host, Ben Emlyn-Jones, breaks down what we know so far about Comet 3i Atlas in this new year edition of The Paranormal Peep Show, with your hosts, Neil Ward, Andy Chaplin and his cat!The Paranormal Peep Show is a regular monthly podcast that goes out on the Paranormal UK Radio Network www.paukradio.com, Spreaker and other audio platforms.Ben Emlyn-Jones is available via his web site at https://hpanwo.blogspot.com/ and you can keep up with his adventures at conferences, live streams, and tours at his Youtube Channel at    / @benthejrporter  Andy Chaplin is a medium and helps run Tuned In Events, for psychic and medium events around North London area, follow him on Facebook for tunedinevents.com.Neil Ward is an artist and author, recent publications available on Amazon include True Tales of the Paranormal and Modern Unsolved Mysteries www.neilwardart.co.uk     Ben refers to scientist Avi Loeb who's work on 3i Atlas can be viewed at / avi-loeb Also mentioned is Youtuber The Angry Astronaut who can be viewed at    / @theangryastronaut  Subscribe and like for more of the Paranormal Peep Show and thanks for watchingBecome a supporter of this podcast: https://www.spreaker.com/podcast/paranormal-uk-radio-network--4541473/support.

Our Solar System is wrapped in a vast, invisible bubble created by the Sun, a protective region that shields Earth and the planets from much of the radiation that fills our galaxy. But until recently, scientists have only had rough sketches of what this boundary looks like and how it behaves. In this episode of Planetary Radio, host Sarah Al-Ahmed is joined by David McComas, professor of astrophysical sciences at Princeton University and principal investigator of NASA’s Interstellar Mapping and Acceleration Probe (IMAP) and Interstellar Boundary Explorer (IBEX) missions, along with Matina Gkioulidou, a heliophysicist at Johns Hopkins Applied Physics Laboratory, former IMAP-Ultra instrument lead, and current IMAP project scientist and co-investigator. Now stationed at the Sun–Earth L1 Lagrange point, IMAP uses 10 instruments to study the heliosphere — the region where the solar wind collides with material from interstellar space. The mission does this by tracking energetic neutral atoms, particles that travel in straight lines from distant regions of the heliosphere, allowing scientists to map areas of space that spacecraft can’t directly sample. McComas and Gkioulidou explain how IMAP builds on the legacy of Interstellar Boundary Explorer, what makes this mission different, and why understanding the Sun’s influence across space matters not just for fundamental science, but for space-weather forecasting and protecting technology and astronauts closer to home.

Our solar system is a dynamic arena where asteroids careen off course and solar winds hurl charged particles across billions of miles of space. Yet we seldom consider how these events, so immense in scale, influence our fragile blue planet: Earth. In Ripples on the Cosmic Ocean: An Environmental History of Our Place in the Solar System (Harvard UP, 2025), Dagomar Degroot traces the surprising threads linking human endeavor to the rest of the solar system. He reveals how variability in planetary environments has shaped geopolitics, spurred scientific and cultural innovation, and encouraged new ideas about the emergence and fate of life. Martian dust storms altered the trajectory of the Cold War and inspired fantastical stories about alien civilizations. Comet impacts on Jupiter led to the first planetary defense strategy. And volcanic eruptions spewed sulfuric acid into Venus's atmosphere, exposing the existential risks of climate change at home. As we stand on the brink of a new era of space settlement, cosmic environments are becoming increasingly vulnerable to human activity. They may also hold the key to slowing the destruction of environments on Earth. Ripples on the Cosmic Ocean urges us to develop an interplanetary environmentalism across a vast mosaic of entangled worlds and to consider the profound connections that bind us to the cosmos and each other.

Spewing lava and belching noxious fumes, volcanoes seem hostile to biology. But the search for life off-Earth includes the hunt for these hotheads on other moons and planets, and we tour some of the most imposing volcanoes in the Solar System.  Plus, a look at how tectonic forces reshape bodies from the moon to Venus to Earth. And a journey to the center of our planet reveals a surprising layer of material at the core-mantle boundary. Find out where this layer was at the time of the dinosaurs and what powerful forces drove it deep below.

As part of the NSF–DOE Vera C. Rubin Observatory First Look event in June 2025, Rubin announced that it had observed thousands of asteroids cruising about our Solar System, about 1,900 of which have been confirmed as never-before-seen. Within the flurry, a team of astronomers has discovered 19 super- and ultra-fast-rotating asteroids. One of these is the fastest-spinning asteroid larger than 500 meters (0.3 miles) ever found. In this podcast, Dr. Sarah Greenstreet discusses these fast spinning asteroids and what makes the Rubin Observatory ideal for discovering these types of objects.   Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Sarah Greenstreet is a tenure-track assistant astronomer at the NSF National Optical-Infrared Astronomy Research Laboratory (NOIRLab) and an affiliate assistant professor in the University of Washington's Department of Astronomy. She is also a member of the Rubin Observatory Community Science Team and has served as the Lead for the Rubin Observatory Solar System Science Collaboration's Near-Earth Objects and Interstellar Objects Working Group for the past seven years. Prof. Greenstreet's research program broadly focuses on orbital dynamics, characterization, and impacts of small bodies across the Solar System, with a particular focus on the rarest and most unusual asteroids.

What does it really mean to enter interstellar space, and what have we learned since humanity first crossed the invisible boundary between our Sun and the stars? In this episode of Planetary Radio, we explore the science of the heliosphere and the realm beyond with Linda Spilker, project scientist for the Voyager mission at NASA Jet Propulsion Laboratory. Drawing on decades of experience with the twin spacecraft, Spilker shares how Voyager reshaped our view of the Solar System’s outer frontier, from the nature of the heliopause to the unexpectedly rich structure of the local interstellar medium. We unpack what Voyager 1 and Voyager 2 have taught us about charged particles, magnetic fields, and cosmic rays beyond the Sun’s protective bubble, and why those measurements have upended earlier ideas about where the Solar System truly ends. Spilker also reflects on the mission’s extraordinary longevity, the ingenuity required to keep the spacecraft communicating across the vastness of space, and what Voyager’s legacy means for future journeys between the stars. Then, in What’s Up, Bruce Betts, chief scientist at The Planetary Society, places Voyager in context, showing how long-lived missions shape the bigger picture of space science and why observing longer can lead to some of our most profound discoveries.

2025 was one of the most consequential years for space policy in modern U.S. history. In this special year-in-review episode, Planetary Radio takes a deep dive into what happened behind the scenes in U.S. space policy and advocacy as NASA faced unprecedented proposed cuts to its science programs. With nearly half of NASA’s science budget at risk, dozens of missions threatened, and months of leadership uncertainty at the agency, this year became a defining moment for the future of space science. Sarah Al-Ahmed is joined by Casey Dreier, chief of space policy at The Planetary Society, Jack Kiraly, director of government relations, and Ari Koeppel, an AAAS science & technology policy fellow, to unpack how this crisis unfolded and how scientists, space advocates, and lawmakers responded. Together, they explore how public advocacy helped shift the conversation in Congress. Plus, in What’s Up, Chief Scientist Bruce Betts explains why stability matters so much for space science and what’s at stake when long-term missions are disrupted. This is the first of two special year-end episodes. Next week, Planetary Radio will look back at what humanity accomplished in space exploration in 2025, from new missions and discoveries to milestones across our Solar System and beyond.

Thirty years ago, NASA’s Galileo spacecraft became the first mission to orbit Jupiter, opening a new chapter in our exploration of the outer Solar System. Over eight years around Jupiter, Galileo transformed how we understand Jupiter and its moons, revealing a powerful and dynamic planetary system, uncovering evidence for oceans hidden beneath icy worlds, and reshaping the search for life beyond Earth. To mark the 30th anniversary of Galileo’s orbital insertion, scientists, engineers, historians, and advocates gathered at the California Institute of Technology for a special symposium: Galileo at 30. In this episode of Planetary Radio, host Sarah Al-Ahmed takes you inside that celebration. You’ll hear how Galileo survived seemingly impossible challenges, how its team adapted when things went wrong, and how its discoveries reshaped planetary science. You’ll hear from key voices in Galileo’s story, including historian Erik Conway, project manager Bill O’Neil, magnetometer principal investigator Margaret Kivelson, Europa Clipper Project Scientist Bob Pappalardo, and Dragonfly mission Principal Investigator Elizabeth “Zibi” Turtle, along with reflections from many others whose lives and careers were shaped by this remarkable mission. Together, they tell the story of Galileo not just as a spacecraft, but as a shared human effort, one whose legacy continues to guide exploration today.
