Hotel Mars with Rand Simberg on Artemis, commercial space options and more.

Hotel Mars with Rand Simberg, August 6, 2025

John and I, with our guest Rand Simberg, focused this one segment Hotel Mars program on the role of commercial space with regards to our effort to return to the Moon. Rand Simberg explainrd that while NASA's Artemis program includes public-private partnerships with SpaceX and Blue Origin, Congress has been requiring the use of the Space Launch System (SLS) for the past 15 years to maintain jobs and workforce. Rand noted that the SLS program faces significant costs, with each Artemis launch averaging $30 billion. The Administration recommended ending the program after 2 more flights but Congress funded 3 additional flights plus associated hardware and infrastructure in the recently passed Big Beautiful Bill.

We expressed concerns about the U.S. losing the moon race to China due to the current focus on the Space Launch System (SLS), which Rand believed is not sustainable. He suggested that the money spent on SLS could be redirected to more innovative and affordable space transportation solutions. David also noted that the NASA administrator position remains unfilled, which he sees as a potential obstacle to advancing space exploration goals.

Before ending our program, Rand discussed the challenges and progress of human lunar lander development, comparing SpaceX and Blue Origin's capabilities. He noted that SpaceX is developing a larger lunar lander but faces uncertainty about refueling on orbit, while Blue Origin's timeline extends to 2030. Rand expressed confidence in SpaceX's ability to make rapid progress once they successfully launch their new version into orbit, addressing concerns about refueling.
