Episode Details

Special Open Lines as the last Space Show for 2025, 12-30-25

Quick Summary

We explored various rocket systems’ capabilities and development status, including SpaceX’s Starship, Blue Origin’s New Glenn, and NASA’s SLS, while discussing the Artemis missions and Gateway project funding. The program ended with discussions about space infrastructure development, sustainable technology implementation, and the future of space exploration, including private sector initiatives and the potential for dual-use technologies.

Detailed Summary

I discussed my appearance on Tom Olson’s radio show. We then discussed the phenomenon of SpaceX employees potentially leaving to start their own space businesses after the company’s IPO, which John Jossy clarified as similar to the “PayPal mafia” concept. Doug expressed skepticism about Mike Griffin’s plan to meet the 2028 moon timeline using existing architecture, noting that Starship’s development is crucial for Artemis III’s success. The conversation also touched on the U.S.’s withdrawal from the Gateway project as depicted by Tom, with ESA now taking full responsibility for its development. This was later challenged and clarified.

We talked about the status of the Gateway project for the Artemis missions, clarifying that Congress has provided full funding for Gateway despite the President’s budget proposal to end it. They debated the necessity of Gateway and the NRHO orbit, with concerns raised about astronaut safety and the potential to strand individuals on the moon. David shared insights from a recent show featuring Mike Griffin, noting lower-than-expected viewership despite high expectations, perhaps due to the holidays. Later we discussed the success of Blue Origin’s New Glenn launch.

Also discussed were the capabilities and development status of various rocket systems, including SpaceX’s Starship, Blue Origin’s New Glenn, and NASA’s SLS. Doug explained that SpaceX’s Starship version 2 is still in development and its payload capabilities are not yet proven, while Blue Origin recently announced plans to stretch their New Glenn rocket to increase its payload capacity. We touched on SpaceX’s Mars cargo landing plans, with Doug noting that Elon Musk’s target of 10-30 tons for initial cargo landings seems low to reduce the number of refills needed, potentially eliminating the need for propellant depots or tanker flights. Marshall raised questions about the orbital reentry and heat shield capabilities of the Starship, suggesting that SpaceX may not fully understand how to handle the heat shield requirements for both lunar and Martian landings until they attempt a test flight.

Our Wisdom Team discussed SpaceX’s progress with their Starship program, noting that while they have had successful ocean landings, a double catch test is an important benchmark for evaluating shield performance. John Jossy mentioned that Relativity Space, led by Eric Schmidt, plans to launch their Taren R rocket late next year with the goal of building data centers in space. The conversation ended with welcoming two new participants, Benjamin Ayala and Twain Knight, who expressed interest in learning about space and discussed their academic backgrounds in physics and aerospace engineering both were students but as you will hear, fizzled out as being guests on the program.

The group discussed the need for NASA to develop a sustainable infrastructure plan for a permanent presence in space, with Gary Barnhard (he joined us via Zoom) emphasizing the importance of establishing clear driving requirements from a science, systems engineering, and architectural design standpoint. Gary shared an example from the International Space Station’s development to illustrate the impact of controversial requirements, highlighting the need for careful consideration of system capabilities. The discussion concluded with Gary outlining plans for a c
