Next Artemis mission will be later than promised
It appears that NASA has already recognized that the next Artemis mission, dubbed Artemis-3 and changed from a lunar landing to an Earth orbit test flight, will not happen on the schedule as first proposed by NASA administrator Jared Isaacman.
During the hearing on Monday, Congressman Hal Rogers (R-Ky.), chairman emeritus of the committee, asked Isaacman about his confidence that Artemis 3 would remain on schedule, given the amount of money allocated for the mission’s landers.
“I’ve received responses from both vendors [SpaceX and Blue Origin],” Isaacman said, “to meet our needs for a late 2027 rendezvous, docking and test [of] the interoperability of both landers in advance of a landing attempt in 2028.”
That’s a shift from Isaacman’s statements during his Feb. 27 Artemis strategy presentation, during which he said, “Artemis 3 will have its opportunity, if we can, by mid-2027, which sets us up for an early ’28 and a late ’28 opportunity [for Artemis 4 and 5].” [emphasis mine]
In other words, Artemis-3 has already shifted from mid-’27 to late-’27. Though Isaacman is pushing hard to speed up the launch cadence of the entire Artemis program, reality is once again proving stronger. We should fully expect Artemis-3 to shift into 2028, partly because the lunar landers — especially Blue Origin’s Blue Moon — might not be ready but mostly because SLS is simply too cumbersome a rocket to stack quickly. Isaacman wants to speed up its launch cadence to once a year. The best we should expect is 18 months to two years.
As for getting two manned lunar landings in 2028, Isaacman might want it but the odds are slim to none. If Artemis-3 flies in late ’27 it will be almost impossible to get SLS ready for a landing mission before the end of ’28.
In the end, these delays will illustrate the need to replace SLS with private commercial launchers.
