Show notes
Our Open Lines program began by delving into a wide-ranging discussion about space exploration topics including nuclear power on the Moon, micro reactors, and SpaceX's Starship program. Together we explored various challenges facing space missions, including regulatory hurdles, technical limitations, and the need for proper infrastructure, while also discussing the financial implications of space programs and the role of government involvement. The conversation ended with updates on upcoming events, including an art show by Dr. Ajay and discussions about Artemis program development, along with announcements about future Space Show programs. Joining us in our Zoom discussion were Marshall Martin, John Hunt, Dr. Sherry Bell, Dr. Ajay Kothari, and John Jossy. We had a call from Tony in Pasadena and a few emails from the live stream listening audience. I also talked about my recent Coast to Coast appearance on one or two specific topics in conjunction with anew Sunday Op-Ed by Mark Whitington.Discussion Review:I opened the discussing by my talking about nuclear power on the Moon during my recent Coast to Coast AM interview. I commented on the surprising opposition from some listeners, I was asked to comment on Secretary Duffy's proposal to explore nuclear power options for lunar habitats and I said that was strategically important for controlling valuable real estate under international space treaties, particularly given China's potential to claim territory around their first lunar nuclear power plant. The discussion highlighted regulatory challenges and the need for ground testing facilities. Both John Hunt and John Jossy agreed that while nuclear power would be necessary for polar region exploration, the timing might be premature without proper infrastructure in place. Again, for our Space Show program I often referred to the Whittington Op-Ed.Our Open Lines group discussed the development and implementation of micro nuclear reactors for lunar bases, with Ajay emphasizing the need for these small reactors, which could power about 1,000 homes, to be developed and tested. Marshall raised concerns about safety zones around these reactors, noting that while traditional reactors require large safety areas, micro reactors would need significantly smaller ones. I mentioned that NPR had reported on 100 kilowatt reactors, which could power a lunar base, and discussed the potential opposition and costs associated with such projects per Whittington. We also touched on the use of nuclear power in space missions and the design of a 50-megawatt reactor by Dr. Ajay, which could be scaled down for smaller applications.We talked a lot about the public understanding and interest in space exploration, with David expressing surprise at the lack of awareness about space program challenges per an email I received directly from a Coast to Coast listener. Ajay suggested this was due to the general audience's focus on other topics like world events and personal interests, while Marshall noted that even educated audiences lack depth of knowledge about space programs. The discussion concluded with John Jossy raising concerns about the technical challenges of an autonomous lunar lander mission by 2030, with Ajay agreeing it would likely be delayed until 2034 or 2035. By the way, I sent two email replies to the Coast listener that email me re challenges and negativity. I never got a reply from him. I also invited him to listen and participate in this OL program. He was a no show.Next, Marshall presented calculations on SpaceX's financial projections, estimating that Elon Musk would need approximately $1 billion for Starship testing and $15 billion for deploying 4,000 Starlink satellites. He suggested that Starlink could capture up to a quarter of the global communication services market, potentially generating between $40 billion to $200 billion annually, which could fund Musk's Mars project and other space initiatives. The discussion concluded with participants agreeing that while Musk's high unfavorable rating (67%) could pose political challenges, his influence on commercial space development would be difficult to replace, as other companies struggle to match SpaceX's progress in reusability and space technology.Next up was our discussion about the potential impact of government regulations on space exploration, with Marshall suggesting that adding bureaucracy could delay missions by 25 years. We also explored the topic of UFOs and UAPs, with John Hunt mentioning that Sean Duffy would be requesting a briefing on the subject. The conversation then shifted to the credibility of information in the UFO community, with David expressing skepticism about government and media integrity, and John Hunt discussing the potential for disinformation to discredit individuals sharing sensitive information. Personally, I believe the topic is so contaminated with bad information from everyone including government that it would be hard to believe anything regardless of the source or disclosure.August 24,SpaceX's Starship launch plans were mentioned with John Jossy reporting the next launch is scheduled for August 24, Sunday at 7:30 AM Eastern time, including testing of Starlink mass simulators and a raptor test in orbit. Ajay raised concerns about Starship's suitability for lunar missions, citing its large size and technical challenges, particularly regarding refueling and thrust-to-weight ratio for moon landings. The discussion concluded that a smaller vehicle like Blue Origin's New Glenn Mark 2 (approximately 30-40 tons) would be more suitable for Artemis missions than SpaceX's HLS concept, which Ajay argued is too heavy and complex for lunar transportation needs.The audience expressed concerns about delays in the Artemis program, particularly for Artemis 3, which is scheduled for 2027 but may be pushed to 2028. They expressed worry about the lack of coordination between independent projects, such as spacesuits and rovers, needed for the mission. Ajay mentioned that Johns Hopkins University's Applied Physics Lab is working on integrating these components through NASA contracts, but there were questions about whether this was being done effectively. The group also discussed the need for a dedicated Artemis program manager to oversee these efforts.The group discussed the importance of the double catch milestone for SpaceX's Starship program, which requires two towers for successful completion. Caller Tony shared information about a YouTube channel by Phil Sloss that provides weekly updates on Artemis development, noting that Artemis 2 is ahead of schedule. We also discussed the need for more transparency in space operations and the potential for inviting Artemis managers as guests to their program. Marshall raised questions about the cost of refurbishing Starship systems for reuse, estimating it at around 10% of the cost of a new system, though others noted that such figures are not publicly available. In learning about the excellent work by Philip Sloss regarding Artemis, I believe I spoke too soon on project management concerns for the Artemis program. I have reached out to Phil to see if he will be a Space Show guest. I will let everyone know if he accepts the invitation.Several additional topics, including the mentioning of Ajay's upcoming art show featuring 30-40 of his paintings which will be available for viewing and purchase on his website. His art website information link is posted on our blog for this program at www.thespaceshow.com. Dr. Sherry Bell mentioned Robert Zubrin's advocacy for nuclear power and his new book "The Case for Nukes." John Jossy shared information about a new book titled "A Dream Renewed: O'Neill's Vision in the 21st Century," which explores space settlements and technology. I announced upcoming guests for the Space Show, including Michael Listner discussing the administration and Comstack on Tuesday, and Mari from a biotech company focusing on artificial organs and space nanomedicine on Friday. For Sunday's show, will invite potential guests to call in and discuss their space-related projects if the scheduled guest does not confirm.Special thanks to our sponsors:Northrup Grumman, 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: 1-866-687-7223For real time program participation, email Dr. Space at: [email protected] Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.
