John Batchelor Hotel Mars with Dr. Simone Marchi, Wednesday, 7-2-25 (2.22MB; download) -- John and I welcomed Dr. Marchi from the SWRI in Boulder, CO to discuss his work pertaining to "The shaping of terrestrial planets by late accretions." You can review his Nature Review paper at https://www.nature.com/articles/s41586-025-08970-8. Briefly, he and his co-author examine the "disproportionate role of the last approximately 1% of planetary growth, or late accretion, in controlling the long-term evolution of the Earth and other terrestrial planets. Late accretion may have been responsible for shaping Earth’s distinctive geophysical and chemical properties and generating pathways conducive to prebiotic chemistry." During our discussion with Dr. Marchi he explained why the last 1% was so vital in the formation of Venus, Mars and Earth. Also Mercury but his comments on Mercury were a bit different. We talked about impacts being similar in nature but since each rocky planet was different, the consequences of the impacts were different. He said they were random, atmospheres made a difference and even shaped some of the consequences. Don't miss his comments about the dinosaurs and their extinction event, the role of luck, and the fact that we need to be looking for exoplanets not just for an Earth twin but also a similar impact history to Earth. When asked about our TRL for being able to do that, well, we have much to learn. In the second half John asked his usual question about having an unlimited budget. don't miss what he had to say about Venus as a priority in this four minute segment.

John Batchelor Hotel Mars with Doug Messier, Wednesday, 6-25-25 (0.97MB; download) -- John and I talked with Doug Messier for a single Hotel Mars program on SpaceX launches, the latest with Starship, including troubleshooting recent launch failures. Doug also talked costs, testing, technical problems, and timelines going forward for essential SpaceX and Starship related programs. Doug reviewed Block 1,2, and 3 for Super Heavy though he said things were not yet clear fro Block 3. Doug was asked about an ongoing risk for debris falling on populated areas. Don't miss his comment on this potential risk factor given he said they had a very thin and narrow needed to fly through over the Gulf.

Dr. Young K. Bae on fusion, Sunday, 6-29-25 (10.81MB; download) -- Dr. Young Bae was our guest for this Zoom program to discuss fusion energy possibilities. We began our discussion with Dr. Bae with a focus on nuclear fusion power and space propulsion. The conversation covered Dr. Bae’s research career, the challenges in developing fusion technology, and potential applications for space. We aimed to conclude with a consensus that both fusion and thorium-based fission could play key roles in future space propulsion, while fission would likely remain the more viable option for terrestrial energy needs. At the start of the program, I reminded listeners of the importance of financially supporting The Space Show, as it is 100% listener-funded.

Dr. Ersilia Vaudo, Thursday, June 26, 2025 (9.08MB; download) -- We welcomed Dr. Ersilia Vaudo to the program from Paris, France to discuss her book, "The Story of Astrophysics in Five Revolutions." This was a fascinating discussion. It is audio archived both on The Space Show site and our Substack site, doctorspace.substack.com plus our video of the interview is also on Substack. I encourage you to watch the video rather than just listen to the program. Your comments are welcome on our blog and on Substack. The full program summary is on both TSS site and our Substack page.

Dr. Karen Lloyd, Sunday, 6-22-25 (7.25MB; download) -- This program sustained serious audio issues.My apologies.
Dr. Karen Lloyd, author of INTRATERRESTRIALS: Discovering the Strangest Life on Earth, joined us for a 63-minute program to explore some of the most bizarre life forms on our planet—organisms that live hundreds to thousands of feet below the Earth's surface. Much of her research focuses on microbial life discovered via deep-sea submersibles like ALVIN. Please see the summary on our website or Substack page for full program details. Thank you.

John Batchelor Hotel Mars, Wednesday 6-18-25 (2.23MB; download) -- John and I welcomed Dr. Enrique Gaztanaga who is at the Portsmouth University, in the UK. The professor proposes an alternative theory of the universe to the established Big Bang theory. Since the JWST has been on line, problems with the Big Bang have been detected with our guest at the lead in proposing his alternative theory which is still under investigation. While listening to this two part program, visit Professor Gaztanaga's excellent website for more detail and a listing of his published articles. See https://darkcosmos.com. You can also read his new publshed paper in In a new paper just published in Physical Review D. Briefly and from his website, "the Big Bang was not the start of everything, but rather the outcome of a gravitational collapse that formed a very massive black hole — followed by a bounce inside. This idea — which we call the Black Hole Universe — offers a radically different view of cosmic origins, yet it is grounded entirely in known physics and observations." Listen to his discussion and check out his papers and more on his theory. I am sure Enrique will be back to Hotel Mars and to The Space Show many times over in the future.
