The Space Show by Dr. David Livingston Dr. Ajay Kothari leads the discussion on possible Artemis alternatives & options.
The Space Show presents Dr. A.J. Kothar via Zoom leading a discussion on how best to return & get infrastructure to the Moon. Tuesday, August 12, 2025
Our discussion centered on Ajay Kothari's proposal to use multiple Falcon Heavy rockets for lunar missions as a cost-effective alternative to NASA’s SLS and SpaceX’s Starship. Kothari argued this method could be implemented within two years at an estimated cost of $400–600 million, and would avoid political pushback by serving as a complement rather than a replacement for existing programs. His plan involves docking multiple upper stages in low Earth orbit, then sending them to the Moon to land infrastructure payloads like nuclear power components. However, participants raised concerns over technical feasibility, payload delivery, landing mechanics, and cost estimates. By the way, do see Ajay’s presentation which has been uploaded to our blog for this program.
Phil presented Ajay’s slides for the group to refer to during our program. Our continued discussion addressed leveraging current SLS/Orion infrastructure, despite general dissatisfaction with their limitations.
Key technical concerns included the following by those in the Zoom meeting with Dr. Kothari:
* Rick questioned the structural viability of connecting multiple upper stages, referencing challenges faced by Falcon Heavy.
* Phil noted possible high costs and a lack of existing control systems.
* Doug challenged Ajay’s assumptions on Falcon Heavy’s actual payload capabilities, prompting references to NASA’s verified data.
* Ajay explained his design accounts for partial reuse and optimized payload delivery, and he agreed to prepare a comparative metrics table for future presentations.
Broader discussion shifted to Artemis program challenges, with skepticism from David and others about the realistic timeline and lack of cohesive leadership. Participants debated whether public-private partnerships, government direction, or commercial entrepreneurs like Musk and Bezos should lead space efforts. Ajay supported a hybrid approach, emphasizing infrastructure-building, not just symbolic landings.
Additional topics included
The strategic value of nuclear power (e.g., Kilopower project) for lunar manufacturing.
* The importance of establishing infrastructure at the Moon’s South Pole, including potential use of water ice as a fuel resource.
* Phil’s critique of NASA’s over-reliance on commercialization.
* Charles’s belief that China will reach the Moon first, citing inconsistent U.S. program management.
* The program concluded with debate over the realistic date for returning humans to the Moon, with predictions ranging from 2028–2029, and acknowledgments that China's progress may influence U.S. urgency.
