The Hill – SpaceX could disrupt NASA plan to return humans to the moon

NASA’s lunar lander concept is a three-stage vehicle that would depart from and return to the Lunar Gateway. The stages would include a transfer vehicle to take astronauts to low lunar orbit, a descent stage that would take them to the lunar surface, and an ascent stage that would return the astronauts to lunar orbit. The ascent stage would dock with the transfer vehicle that would then return to the Gateway.

The SpaceX Starship will be able fly to the moon and Mars after re-fueling in orbit. The Starship is not a three-stage vehicle, but a single-stage one. Moreover, it doesn’t need the Lunar Gateway to reach the moon, though the cis-lunar facility might prove useful to operate as a staging area for a reusable lunar lander.

SpaceX founder Elon Musk anticipates Super Heavy/Starship being available long before 2028. Even if one tacks on a few years to Musk’s admittedly optimistic timeline of 2022-24, the spaceship being developed by SpaceX promises to disrupt NASA’s carefully crafted plans for developing an Earth-moon transportation system.
