Open Lines Space Show Discussion Featuring Multiple Current Space Topics
Description
OL for Sunday, 8-24-25 Meeting summary
Our Open Lines program began with members of our Advisory Board in the Zoom meeting on casual conversation about the upcoming Starship test 10 flight. The group then explored various space-related topics including more Starship test flights, SpaceX, lunar landing architectures, and NASA's Artemis program, while also discussing the importance of public communication about space exploration and its potential benefits. The conversation ended with discussions about scientific discoveries, upcoming shows featuring space policy experts, and an art showing by Dr. Kothari, along with additional updates about the upcoming Starship launch.
Our pre-program conversation ended with David announcing upcoming Space Show programs, including a discussion with Dr. Namrata Goswami about national security and the Chinese space program, and a potential interview with Greta, an emeritus professor from Yale who has a new thesis about the extinction of dinosaurs. Space Show program participants included Marshall Martin, John Jossy, Rick Kwan, Michael Listner, John Hunt, and Dr. A.J. Kothari.
We started the actual meeting by talking about the upcoming Starship test flight (it was postponed), with Marshall estimating a 60% chance of success. They debated how success should be measured, with John Jossy noting that while not blowing up is a success, completing a good percentage of experiments is also important. Rick and Marshall discussed the transition from version 2 to version 3 of Starship, with Marshall noting that the main upgrade is replacing Raptor 2 engines with Raptor 3 engines. The group also touched on the challenges of keeping the dry weight low while maximizing payload capacity for Mars missions. They concluded that a failed test would likely have a cascading effect on schedules, particularly for Artemis, but that SpaceX has the financial resources to continue development.
The group discussed the number of test flights needed for SpaceX's Starship, with Marshall suggesting 11 flights based on his spreadsheet analysis. They debated the risks of betting on the Artemis program's timeline to beat China to the moon, with John Hunt and David expressing concerns about the current infrastructure and delays. Rick noted that Chinese technology is rapidly improving, potentially making it harder to catch up. The discussion concluded with David suggesting that Congress might not be as motivated to play catch-up with China as previous generations were with the Soviets.
In addition, we discussed potential lunar landing and return architectures, with Marshall proposing to use Dragon in the nose of a Starship for moon landings, though Dr. Kothari pointed out that Dragon lacks sufficient delta-V for lunar takeoff. Ajay raised concerns about the need for NRHO operations to continue despite budget constraints, while Marshall suggested repurposing Starship as a moon base by tilting it and connecting to future Starships, which would create a legal claim on the moon. The discussion concluded with John Jossy noting that current law mandates continued use of SLS, Orion, and Gateway through Artemis 5, suggesting any architectural changes would need legislative approval.
The group discussed NASA's Artemis program and leadership challenges. David expressed concerns about the lack of full-time NASA leadership and the need for better communication to the general public about space exploration's importance. Michael Listner suggested that a permanent NASA administrator might not be necessary and that the current political situation would likely remain unchanged for the foreseeable future. The group agreed to attend a special Space Show program with Mike Gold on August 28th to further discuss these issues.
The group discussed the importance of both informing the public and conducting scientific/engineering work in space. Rick presented three key space manufacturing opportuni
