Why it matters
NASA selected SpaceX to develop a modified version of Starship as a Human Landing System, or HLS, for its Artemis lunar program, which aims to take astronauts to the Moon and establish a long-term human presence there. NASA has invested nearly $7 billion into the wider HLS program and expects to spend more than $18 billion by 2030.
NASA welcomed the recent Starship catch. Administrator Jared Isaacman described it as “almost magic” and said it brought the program “one step closer” to returning Americans to the Moon.
The central challenge in getting astronauts to the Moon is fuel. Starship can’t leave Earth carrying all the rocket fuel, or propellant, it needs to reach orbit and then continue to the Moon. SpaceX therefore plans to refuel Starship in orbit, using other spacecraft to deliver the fuel it needs before it heads for the Moon.
Exactly how many tanker launches will be necessary remains unknown. Charlie Precourt, a member of NASA’s Aerospace Safety Advisory Panel suggested that the operation could require as many as 22 launches, while SpaceX CEO Elon Musk has argued that the figure will be closer to six or eight.
No mission has yet demonstrated fuel transfer on the scale required by the Starship lunar architecture. SpaceX still needs to prove it can transfer large amounts of fuel and keep that fuel cold enough until it’s needed.
SpaceX is expected to inspect the recovered spacecraft and continue testing the upgraded Starship system, while also investigating the loss of the Super Heavy booster. The company must demonstrate reliable recovery of both stages, repeatable orbital missions, docking and large-scale propellant transfer.
NASA and SpaceX are also working toward an uncrewed lunar demonstration of Starship HLS before astronauts use the vehicle. NASA says its HLS program is working toward returning astronauts to the Moon by 2028, although NASA’s Office of Inspector General has continued to raise concerns about the technical challenges and schedule risks facing the HLS program.
