SpaceX Lunar Dream Stalled by Refueling Hurdles
11 Mar
Summary
- Starship's moon landing target has been pushed back significantly.
- In-space refueling is a major, unattempted technical challenge.
- NASA aims for a 2028 moon landing, with SpaceX as lead lander.
SpaceX's Starship faces substantial development delays, impacting NASA's Artemis program goal of returning astronauts to the moon. Originally slated for a 2024 landing, the target has been extended, with NASA now aiming for 2028. A critical and unproven challenge for Starship is its in-space refueling capability, a process never before attempted at this scale.
To enable a lunar landing, SpaceX must launch over eleven additional Starships to serve as orbital fuel tankers. This intricate operation involves multiple transfers of cryogenic liquid methane and oxygen in low-Earth orbit, a risky endeavor given the volatile nature of the propellants and increasing space traffic. NASA acknowledges this technical complexity as a significant risk to the program.
Despite these challenges, NASA has added an extra Artemis test mission and is working with companies like SpaceX and Blue Origin to accelerate lunar capabilities. SpaceX has conducted 11 test flights of its Starship system since 2023, demonstrating progress while NASA maintains its 2028 target for human moon landings.
