Bob Zimmerman returns to The Space Show For His Recent Artemis II Op-Ed, Artemis III comments, Starship, human spaceflight safety and much more.

The Space Show presents Bob Zimmerman, Tuesday, 1-20-26

Quick Summary

We started this Space Show program with Bob Zimmerman with discussions about space exploration policies, private industry involvement, and the current state of various space companies, including ULA and Blue Origin, along with a brief mention of Robert’s book “Conscious Choice.”

Detailed Summary

Bob and David discussed the potential impact of a space program incident with Artemis, comparing it to past accidents and suggesting it could lead to a significant overhaul of NASA’s programs. The conversation touched on the Artemis flight and the Mars Reconnaissance Orbiter. Bob opened up referring to his Op-Ed in which he criticized the press coverage of NASA’s Artemis II mission, accusing journalists of being overly positive without addressing engineering concerns. He expressed concerns about the mission’s safety, particularly regarding the untested life support system and the damaged heat shield, which NASA has only partially addressed by adjusting the flight path. Zimmerman compared the situation to SpaceX’s more rigorous testing requirements for its Crew Dragon capsule, highlighting NASA’s double standard in demanding multiple uncrewed test flights from commercial partners but not from its own SLS rocket.

Bob also expressed concerns about NASA’s decision to proceed with the Artemis II mission, citing inadequate testing and a culture that prioritizes schedule over engineering safety. He highlighted that the mission lacks critical testing, such as a heat shield test using Falcon Heavy, and criticized NASA’s management for not standing up to political pressure to achieve a lunar landing before the current administration’s term ends. Marshall suggested using an alternative method to test the heat shield, but Bob explained that NASA had already lost valuable time and was planning to use a different design for the next mission. Several in the group agreed that the Artemis II mission, while potentially successful, could be counterproductive by allowing NASA to continue misleading the public about the program’s readiness.

Next, Bob went after the Senate launch system as poorly managed and equipment-poor, noting that Congress created the rocket without a clear mission, which NASA is now struggling to define. He expressed more concerns about the Orion heat shield’s untested design and emphasized the importance of fixing problems rather than working around them, especially when human lives are at stake. Phil suggested that sophisticated simulations could reduce the number of flights needed, but Robert argued that ultimately, hardware must be tested in real-world conditions. David pointed out that NASA’s statements indicate they plan to use a new heat shield design in a future mission, which Phil initially criticized but Bob defended as a necessary step, albeit one that should have been tested beforehand.

The Wisdom Team discussed concerns about NASA’s approach to the Orion and SLS mission, with Bob being critical of NASA’s management and politicians for prioritizing cost savings over safety by reusing shuttle parts. Dallas and Joe expressed skepticism about the mission’s cost-effectiveness and engineering decisions, while David emphasized the need for Congress to question NASA’s choices. The discussion highlighted the tension between political pressures and engineering realities in space exploration, with no clear solutions proposed by the end of the meeting.

Bob went on expressing skepticism about NASA’s Artemis program and the Space Launch System (SLS), arguing that the real space program in the United States is currently led by SpaceX. He criticized the Artemis mission as trivial and not historically significant, advocating instead for fostering a robust American private industry in low Earth orbit and beyond. Dr. Kothari questioned Bob’s views, particularly regarding his recent op-ed, and discussed the potential dangers of the Artemis II mission. They also touched on alternative testing methods for the Orion spacecraft and the need for infrastructure development on the Moon.

The Wisdom Team discussed the role of government and private enterprise in space exploration, with Bob emphasizing the importance of competition and innovation among various American space companies. Phil argued that NASA’s leadership is crucial for guiding private industry and managing risks, while Bob suggested that NASA should set goals and provide a framework for private companies to achieve them without micromanaging the process. Joe noted that the Artemis Accords might be the most enduring legacy of the Artemis program.

The tem discussed the Artemis Accords, which Bob explained were initially introduced by the Trump administration as a way to encourage private enterprise in space and potentially lead to changes in the Outer Space Treaty that prohibits property rights. Joe noted that Portugal had recently joined the Accords, bringing the total to 60 nations, with many post-Soviet countries participating. Phil suggested that allowing property rights in space could help redirect expansionist leaders’ attention from Earth to space exploration, while Bob agreed with this approach and proposed establishing international rules similar to the Homestead Act to allow nations to claim territory under specific conditions.

Bob discussed the Mars Reconnaissance Orbiter’s aging issues, noting an increase in anomalies and color dropouts due to the camera’s degradation. Alfred McEwen explained that the problem is being managed by adjusting the camera’s temperature, but more funding is needed for calibration. Robert highlighted the orbiter’s importance in revealing Mars’ icy nature and its potential for future human settlement. The group also discussed private and government missions to Venus, including Rocket Lab’s delayed mission, NASA’s canceled missions, and India’s planned Venus orbiter. Phil mentioned China’s proposed Venus Volcano Imaging and Climate Explorer mission, though its launch details remain unclear.

The group discussed current and future planetary missions, with Bob noting that NASA’s Venus missions are on hold and the U.S. has limited active planetary exploration compared to other countries. They explored Blue Origin’s potential to increase competition in space travel, with Bob expressing hope that under new CEO David Limp’s leadership, the company could become more competitive with SpaceX. The discussion also covered Blue Origin’s orbital reef project, which our guest described as currently inactive, and Marshall inquired about cost reduction goals in space travel, to which Bob and Phil noted that while Blue Origin’s David Limp has mentioned reducing costs by two orders of magnitude, no company has yet achieved even a one-order reduction.

The group discussed the potential for terrestrial nuclear power plants, noting that while there is growing demand due to AI data centers, there remains significant public resistance. Bob expressed concerns about the “delusional” enthusiasm for AI, particularly in journalism where AI-generated articles are often inaccurate and inappropriate. The conversation shifted to space industry developments, with Ajay discussing small modular reactors (SMRs) and Generation 4 reactors that could serve both propulsion and energy needs. The discussion concluded with Bob emphasizing the need for multiple space companies beyond SpaceX, highlighting the importance of competition and redundancy in the industry.

As we were nearing the end of the discussion, we focused on the current state and future of ULA, with Bob noting that while ULA has significant contracts with Amazon and Boeing, its Vulcan rocket lacks reusability and may struggle to compete with emerging reusable rockets like Starship and Neutron. The team discussed the leadership changes at ULA, with an interim leader appointed but no permanent replacement named yet. The conversation concluded with a plug for Bob’s book “Conscious Choice” which explores the origins of slavery in Virginia and its relevance to space exploration, with David and Phil confirming they had read the book and found it informative.
