    First on Mars - The 50th Anniversary of Viking 1

    This week, we cover how Starship Flight 13 finally prepares to launch amid a legal battle over SpaceX's proposed land swap at Starbase, plus a Chinese Long March 3B rocket gets struck by lightning during liftoff, yet still delivers its satellite safely. Then, guests Dr. Pascal Lee and astrobiologist Dr. Penny Boston join the show to mark the 50th anniversary of Viking 1's landing on Mars and revisit the mission's groundbreaking life-detection experiments and the decades-long controversy over what they actually found. The conversation traces Mars exploration from the earliest Mariner flybys through Viking's ambiguous, still-debated results—later explained by perchlorates in the Martian soil—and the fierce scientific rivalry the findings sparked. Join us! Headlines: SpaceX Starship Flight 13 faces engine and weather delays ahead of launch SpaceX land swap proposal sparks conservation group lawsuit over Rio Grande Valley wildlife preserve Chinese Long March rocket survives dramatic lightning strike during launch Main Topic: 50th Anniversary of Viking Mars Landers—Search for Life on Mars The evolution of Mars exploration from telescopes to Viking lander Early Mars missions: Mariner flybys, Soviet attempts, and breakthroughs in orbital imaging Viking 1 and 2: Ambitious design, life-detection experiments, and landing impact Mixed public and scientific reactions to Viking's first iconic Mars surface images Technical overview of the Viking biology experiments and their controversial results The unresolved debate: Did Viking detect life or chemical reactions on Mars? Personal accounts of key scientists, scientific disputes, and the "Wolf Trap" experiment that never flew Lessons from Viking: Limitations of technology, extremophile discoveries, and shifting strategies for detecting life The scientific case for seeking life in Martian caves and subsurface environments Critique of current and future Mars missions: Perseverance rover findings and value of Mars Sample Return Exploring planetary protection, contamination risks, and the challenges of certifying Martian samples= Key takeaways for future missions—bold searches, new technologies, and the ongoing quest for answers Hosts: Rod Pyle and Tariq Malik Guests: Pascal Lee and Dr. Penelope Boston Download or subscribe to This Week in Space at https://twit.tv/shows/this-week-in-space.

    SpaceX Goes to War! - And Other Space Headlines

    This week we're jumping into the space headlines for the past few weeks. It's been busy, and some exciting things are happening! A couple of companies are moving into the space solar power arena--something we've long advocated--and that's welcome progress. Starship is set to fly Starship test number 13, and a lot is riding on this--the system is overdue for some proof of concept to keep up with NASA's HLS contract. An exoplanet spotted a decade ago has shown signs of a potentially habitable atmosphere; there are landslides--big ones--on Pluto, and evidence of "space candy" sugars in an interstellar cloud are in the news. Finally, SpaceX is doubling down on their big defense contracts with a well-funded US Space Force. Join us for all the latest! Headlines: SpaceX Starship Flight 13 Launch Aborted Due to Engine Issue Meteorite Crashes Into New Jersey, Preserved Sample Fuels Origins of Life Research Discovery of Atmosphere Around Habitable-Zone Exoplanet LHS 1140 b NASA Moon Tree Planted After Artemis 1 Mission Reflect Orbital to Launch Mirrors in Space, Sparking Astronomer Backlash Landslides Found on Pluto Could Bury Entire Cities Rare Sugar Found in Interstellar Cloud Hints at Building Blocks of Life SpaceX's Growing Military Launch Contracts and Pentagon Ties Space Development Agency's Expanding Satellite Constellation for Space Force Starship's Dual Focus: NASA Moon Landings vs. Mars and Satellite Deployment Artemis 3 Updates: New Renderings, Docking Plans, and Starlink HD Laser Payloads Defense Innovation Unit's Push for Space-Based Power Beaming Technology Pulse Space and Laser-Based Satellite Power and Communication New Satellite Concept to Detect Nuclear Devices in Orbit Amid Global Security Concerns Hosts: Rod Pyle and Tariq Malik Download or subscribe to This Week in Space at https://twit.tv/shows/this-week-in-space.

    Which Way to the Moonbase? - With Dr. Pascal Lee

    We've been hearing a lot about NASA's new moonbase plans, and they are ambitious. Starting with Artemis V (so far), the US plans to begin preparations for a permanent base situated in the south polar regions of the moon. Details are somewhat fluid, but one thing stands out: the poles are likely to be the most challenging places to set up shop in an already hostile environment. Planetary scientist Dr. Pascal Lee joins us to discuss moonbase siting options and why the poles may not be the best choice at first. Headlines: China Demonstrates Impressive Rocket Landing and Catch Mechanism New Horizons Probe Awakens to Transmit Deep Space Data Wally Funk, Last of the "Mercury 13," Passes Away West Coast Rocket Launch Alert: SpaceX Falcon 9 Visual Spectacle Main Topic: Moon Base Strategy and Location Debate History and Evolution of U.S. Moon Base Plans NASA's New Multi-Phase Moon Base Timeline and Missions Strategic and Logistical Challenges of South Pole Moon Bases Arguments for a Centralized, Benign Location for Moon Infrastructure Commercial and International Partnership Models for Lunar Operations Role of Robotics and AI in Moon Exploration and Prospecting Lessons from Antarctic Base Logistics Applied to the Moon Potential for Tourism and Commercial Development on the Lunar Surface Hosts: Rod Pyle and Tariq Malik Guest: Pascal Lee Download or subscribe to This Week in Space at https://twit.tv/shows/this-week-in-space.

    Dark Matter Intelligence - With Physicist Dr. Daniel Whiteson

    We've had endless conversations about aliens and first contact--but what if a conversation with other intelligences is beyond our scope? Dr. Daniel Whiteson, particle physicist at CERN's Large Hadron Collider and professor at UC Irvine, joins us to explore less conventional thoughts on first contact. We look at the challenges of communicating with extraterrestrial intelligences, potential difficulties of communicating via non-terrestrial mathematics and physics, and the possibility that extraterrestrials might actually be terrestrial... but existing as denizens of the dark energy universe. One might be sitting in your lap right now! Join us for the far-ranging discussion.

    Moon Man - With Former NASA Administrator Jim Bridenstine

    There are NASA Administrators, and then there are NASA Administrators—all are very accomplished individuals, but some stand out for their unique backgrounds and on-the-job successes, and Jim Bridenstine is one of the latter. Entering service as the new NASA Administrator in 2017 with a background as a Navy pilot, Congressman, and museum director, he was an unconventional choice, and faced some headwinds in the appointment—but Jim turned out to be exceptional in the job, especially given the state of NASA when he took it on.
