Musk disputes NASA safety panel's lunar launch estimates
NASA's Aerospace Safety Advisory Panel suggested approximately 22 launches might be required to support the Human Landing System variant of Starship for Artemis lunar missions, but Musk challenged this estimate as too high. The disagreement stems from the need for in-space propellant transfers between spacecraft—a capability that remains technically unproven at the scale required for Artemis. SpaceX has completed one Starship orbital test flight to date, with many more tests planned before attempted lunar landings.
Key points
- NASA panel estimated ~22 launches needed for Artemis lunar landing; Musk disputes as too high
- Musk claims actual requirement is 6-8 launches
- Challenge involves perfecting cryogenic propellant transfer in space
