NASA may delay crewed lunar landing beyond Artemis 3 mission
NASA's Artemis 3 mission, set to return humans to the Moon in 2025, might not involve a crewed landing after all, an official said Tuesday.
Jim Free, the space agency's associate administrator for the Exploration Systems Development Mission Directorate, told reporters in a briefing that certain key elements would have to be in place -- notably the landing system that is being developed by SpaceX.
Should that not be ready on time, "We may end up flying a different mission," he said.
Under the Artemis program, NASA is planning a series of missions of escalating complexity to return to the Moon and build a sustained presence in order to develop and test technologies for an eventual journey to Mars.
The first, Artemis 1, flew an uncrewed spacecraft around the Moon in 2022. Artemis 2, planned for November 2024, will do the same with crew on board.
But it is during the Artemis 3 mission planned for December 2025 that NASA has planned its grand return to the Moon with humans for the first time since 1972, this time on the lunar south pole, where the ice can be harvested and turned into rocket fuel.
Elon Musk's SpaceX has won the contract for a landing system based on a version of its prototype Starship rocket, which remains far from ready. An orbital test flight of Starship ended in a dramatic explosion in April.
Free said NASA officials had visited SpaceX's Starbase facility in Texas a few weeks ago to "learn where they are with the hardware, trying to understand their schedule some more."
Though he found the visit insightful, he said he remained concerned "because they haven't launched," and will need to do so multiple times before the rocket will be ready.
What's more, delays to Starship have knock-on effects because the spacesuit contractor needs to know how the suits will interface with the spacecraft, and simulators need to be built for astronauts to learn its systems.
He added that NASA will update the public in the near future once it has had time to "digest" the information gathered during the Starbase visit.
