This Week in Space (Video)

It's our annual holiday special for 2025, in which we look back at the past year in space—its ups, its downs, its all-arounds. What a year it's been, and after all the challenges and hullabaloo, we're grateful in a post-Thanksgiving fashion to welcome Jared Isaacman, at last, as the new NASA Administrator. What he will do and how remains largely unknown, but we do believe he has the nation's interests at heart, and the man knows people are watching. But there are a lot of other stories and we've done our best to stuff as many as we can into this virtual Christmas space stocking! Please join us for this year-end roundup! Headlines & Looking Back at 2025: New Executive Order Targets Space Superiority Starlink Satellite Breaks Up in Orbit, SpaceX Responds Interstellar Comet ATLAS: Extraterrestrial Conspiracies and Public Fascination Isaacman Confirmed as New NASA Administrator Project Athena: NASA's New Strategic Direction?

This week, we talk with our favorite Newspace Buccaneer, Jeffrey Manber. When so many people were touting their private spaceflight dreams in the 1980s, Manber took the next enormous stride and actually made it happen. He formed the Office of Space Commerce within the US Department of Commerce at the invitation of the Reagan administration, forged the first commercial relations with the then-Soviet Union, bridged that into the post-USSR period, and was responsible for the first commercial spaceflight to the then-mothballed Soviet-era Mir space station with a crew that stayed there for 70 days. He then went on to develop a variety of commercial space enterprises, from the first commercial platform to release smallsats from the ISS to initiating the Bishop airlock that became part of the space station. He also started Nanoracks, the first privately developed and standardized satellite deployment mechanism to fly. Finally, he initiated Starlab, the private space station currently under development by Voyager Technologies and a consortium of aerospace companies. Join us for this very special episode with one of the key founders of NewSpace!

Jared Isaacman, the billionaire entrepreneur, philanthropist, and private astronaut, took on Capitol Hill this week in his second confirmation hearing as President Trump's pick for NASA's next leader. Here's what it could mean, plus: A Russian cosmonaut got kicked off a SpaceX flight for allegedly trying to steal spacecraft secrets, China's 1st reusable rocket Zhuque-3 reached orbit, but crashed and burned (and exploded) during landing, and Russia accidentally wrecked the only launch pad it has for astronauts with Thanksgiving's new ISS crew launch.

Were you inspired by "Star Trek" (or one of its innumerable spinoffs) as a young person? We know we were, so it was a pleasure to invite Glen Swanson, author of the new Star Trek history book "Inspired Enterprise" onto the show. We've all heard lore about the original series, but Swanson, who was previously the Chief Historian at the Johnson Space Center, used his prodigious skills to perform a deep dive into the topic. From Gene Roddenberry's original inspiration to working with Caltech, the RAND Corporation, and NASA; and on to the design of the good ship Enterprise itself (and the very popular AMT models that followed), this book provides everything you need to know to be a certified Trekker. Headlines: Comet 3I Atlas confirmed as a comet, not a spacecraft & NASA releases new images and details of the comet SpaceX's Starship Version 3 booster suffers damage during test Uranus reaches yearly opposition—best viewing opportunity Main Topic: The Real Inspirations Behind Star Trek Glen Swanson shares career highlights as a NASA historian and magazine founder How Gene Roddenberry's background and influences shaped Star Trek NASA's direct involvement and technical guidance for Star Trek's creators The significant role of the aerospace industry, Rand Corporation, and real-world science in Star Trek's development The story behind NASA and the Smithsonian Enterprise shooting model connections AMT's plastic model kits fueled fan obsession and supported the show's visuals Influences from movies like Robinson Crusoe on Mars and Forbidden Planet Space Station K7 design's origins traced to NASA and Douglas Aircraft concepts Star Trek's impact on inspiring real-life astronauts and the space community Glen Swanson's book, "Inspired Enterprise," and how you can get a signed copy Hosts: Rod Pyle and Tariq Malik Guest: Glen Swanson Download or subscribe to This Week in Space at https://twit.tv/shows/this-week-in-space.

Snow on the moon? Yes, though not recently... but maybe billions of years ago. Recent discoveries indicate that the early moon, orbiting just 20,000 miles above our planet at the time, may have shared a dynamic magnetic field with that of the Earth, resulting in the moon having an early atmosphere about twice as dense as the Martian atmosphere is today! This has wide implications for planetary science, but perhaps our favorite is that it may have snowed both carbon dioxide and water ice on the moon back in the day. We're also talking about the amazing launch and recovery of New Glenn, the plight of the Chinese taikonauts aboard the Tiangong space station, and a recent SpaceX memo about—no surprises here—a delay to their lunar landing program for Artemis III.

As you may or may not know, NASA's Goddard Space Flight Center is in the administration's crosshairs. With cuts to their budget and staffing beginning under Elon Musk's DOGE, it has taken a different form with the government shutdown. Employees furloughed or retired from critical programs, laboratories shuttered, and entire facilities gutted--all without the approval of Congress. By the time the shutdown is over, NASA's primary research center--and the one most responsible for what many are now calling "the C-word," climate science--will be a shell of its former self. Josh Dinner, who recently completed a months-long investigative report, joins us. Also: Jared Isaacman is back in the running as NASA chief, the 25th anniversary of the ISS, and China now working with the US on orbital dangers. Headlines: Trump Renominates Jared Isaacman as NASA Chief, Sparking Political Drama 25 Years of Continuous Astronaut Presence on the International Space Station China Initiates Rare Satellite Collision Avoidance With NASA Apollo-Era Radio Telescope That Spied on Soviet Satellites Up for Sale Mars ESCAPADE Missions Twin Probes Prepare for Launch on New Glenn Rocket Main Topic: NASA's Goddard Space Flight Center Crisis Goddard Hit by Accelerated Building Closures and Funding Cuts NASA Employees and Lawmakers Accuse Agency Leadership of Breaking the Law Climate Science and Political Motives at the Core of Goddard's Struggles Union Power Stripped After NASA's Reclassification as National Security Agency High-Profile Missions Like Hubble, the Nancy Roman Space Telescope, and LISA Facing Uncertainty Loss of Talent and Institutional Knowledge Threatens Future Space Projects Congress and the Public Urged to Support, But Outlook Remains Grim Could New Leadership Reverse the Changes Brought to Goddard, or Reinforce Goddard's Decline?

Lander, lander, who's got the lander? Last week, acting NASA Administrator Sean Duffy announced that the agency would be re-opening the contract for the Artemis III lunar lander, which had previously been let to SpaceX to be fulfilled by their Starship Human Landing System. Unfortunately, that effort is well behind schedule, and the Trump administration has made landing astronauts on the moon, before China does, a national priority. With multiple refuelings and landing tests required, there is concern that SpaceX may not be able to fulfill their commitment before China's announced landing date of 2030. Elon Musk responded to the announcement with characteristic tack, with phrasing like "Sean Dummy" and him having a two-digit IQ. Mike Wall of Space.com joins us to dive into this rapidly evolving story. Headlines: Texas vs. the Smithsonian: The Fight Over Space Shuttle Discovery Heats Up Artemis II Moon Rocket Fully Assembled, Awaits Rollout California Senator Pushes State Funding to Support JPL Amid Federal Cuts SpaceX Sets Record with 139 Launches, ULA Struggles to Keep Up New Super-Earth Discovered Just 20 Light Years Away Near Gemini Main Topic: The Lunar Lander Dilemma for Artemis III and Beyond NASA Acting Chief Sean Duffy Announces Reopening Artemis III Lunar Lander Contract SpaceX's Starship Faces Orbital Refueling Challenges and Timeline Doubts Blue Origin Lurking in the Wings: Can They Deliver a Lander On Time?

If we're ever to make Mars a second home, we have some serious housekeeping to do... as in a total renovation. The Red Planet has little atmosphere, no radiation shielding, and some seriously toxic soil. How can we make it more Earthlike... and should we? Dr. Erika Alden DeBenedictis joins us to discuss how terraforming might work, how it could be done in decades instead of millennia, and the questions surrounding the ethics of changing another planet to suit humanity's needs. We say it's a trailer park of a planet, but the best bet for human expansion. Dr. Rick Jenet is this week's co-host. Join us for the conversation! Headlines: NASA aims to place a nuclear reactor on the moon by 2030, competing with China's similar plans for the Moon. NASA's planned commercial space stations are facing delays. As ISS retirement nears, the U.S. risks losing its foothold in low-Earth orbit within the coming years. SpaceX hits 100 launches in 2025, dominating global orbital launch activity and enabling rapid rocket reuse. Main Topic: High-Speed Terraforming of Mars Guest Dr. Erika Alden DeBenedictis shares new, biotech-driven concepts for terraforming Mars much faster than traditional proposals. Dr. DeBenedictis shares a modern understanding of Mars' past and present environment, including radiation, toxic perchlorate-laced soil, and thin atmosphere. Discussion on the importance and challenges of Mars Sample Return for accurate soil and resource analysis. Modern synthetic biology as a tool for creating microbes tailored for Martian soil and future terraforming. A step-by-step outline by Dr. DeBenedictis on building a breathable Mars atmosphere via engineered photosynthetic microbes, engineered atmospheric warming, and greenhouse construction. Exploration of the ethical considerations and philosophical implications of turning Mars into a habitable "garden," weighing preservation versus transformation. Dr. DeBenedictis makes a case for Martian settlement, terraforming technology, and legal and resource challenges for commercial space expansion. And Dr. DeBenedictis' vision for Mars' future as a unique, partially Earth-like biosphere with new opportunities in planetary stewardship and human adaptation of the planet.

The United Nations has mediated conflicts since its founding in 1945. That domain of involvement extended into space in 1967 with the Outer Space Treaty. Today, their role is increasingly active with more and more nations entering space and the private sector getting into the game. The US's space-related branches, UNOOSA (the UN Office of Outer Space Affairs) and COPUOUS (UN Committee on the Peaceful Uses of Outer Space), are busy. Many years ago, the National Space Society gained permanent UN observer status, which is much less passive than the name sounds. The organization has addressed the committees on more than one occasion and is working to influence the policy for space flight positively. Dr. Rick Jenet has been instrumental in these efforts and joins us in explaining the landscape of newspace, international space efforts, and the organization's future initiatives.Headline Space Shuttle Discovery Controversy: Rod and Isaac discuss the proposed $85 million move of the Space Shuttle Discovery from the Smithsonian to Houston, plan that faces obstacles from the Smithsonian, which holds the rights to the shuttle. Main Topic: UNOOSA & Dr. Rick Jenet The National Space Society's UN Observer Status: Dr. Jenet explains that the NSS gained permanent observer status at the UN in 2001. The NSS uses this privilege to inform delegates by providing research and presentations. UNOOSA and COPUOS Explained: Dr. Jenet clarifies that UNOOSA organizes the Committee on Peaceful Uses of Outer Space (COPUOS). While UNOOSA maintains a registry of space objects, COPUOS is the body of 104 member states that develops legal frameworks. Outer Space Treaty of 1967: Dr. Jenet talks about the Outer Space Treaty, a global treaty dating back to the Cold War era that governs how state actors behave in space. He that the treaty's language on property ownership is being re-examined due to the rise of commercial space activities. Space Traffic Management and Orbital Debris: Dr. Jenet highlights that discussions on space traffic management and orbital debris are in their early stages. These discussions focus on basic tenets like coordination and information sharing. Lunar Activities and Resource Utilization: The development of policies for lunar exploration and resource extraction is also an area of new activity. UNOOSA's "Action Team for Lunar Activities Consultation," with co-chairs from Romania and Pakistan, coordinates the future of humanity's return to the moon by aligning different national initiatives. The "Regulation Sandbox" Concept: Dr. Jenet discusses the "regulation sandbox" concept, where existing regulations for an area with commercial potential, for example a lunar ice deposit, are set aside for a limited time to allow a new set of rules to be tested. This concept could be applied more boradly to space launch or ISRU. Why the Public Should Care: Dr. Jenet emphasizes that the public should care about these efforts because these high-level discussions will lead to international laws governing the behavior of all actors in space, including private companies and entrepreneurs. Early awareness of these frameworks will be less painful for startups later on. These show notes have been truncated due to length.
