NASA managers say SpaceX Super Heavy/Starship rocket and lunar lander testing may push Artemis crew landing to 2026.
NASA continues to target the end of 2025 for the first Artemis astronaut moon landing, but SpaceX faces a daunting number of test flights with its Super Heavy rocket and Starship lunar lander between now and then, raising concerns the flight"probably" will slip into 2026, a top NASA manager says.
"They have a significant number of launches to go," he said."And that, of course, gives me concern about the December of 2025 date." The Artemis 3 mission, tentatively scheduled for launch in December 2025, will carry astronauts to the lunar surface. They will fly to the moon in an Orion capsule launched by an SLS rocket and dock with SpaceX's Human Landing System, or HLS, a variant of the Starship upper stage launched atop the company's Super Heavy booster.
But the Starship lander will burn up much of its propellant reaching low-Earth orbit, and multiple Super Heavy/Starship flights will be needed to re-fill its tanks before the spacecraft can head for the moon. The Super Heavy/Starship is more than twice as powerful as NASA's SLS, generating 16 million pounds of thrust at liftoff with 33 company-designed Raptor engines burning methane and liquid oxygen. The Starship upper stage is equipped with six Raptors.
