Isaacman Clears Artemis 2 for April Launch — And Signals More Changes Are Coming

NASA's Artemis 2 mission is go for an April 1 launch, the agency confirmed this week following a two-day flight readiness review. But Administrator Jared Isaacman is making clear the Artemis restructuring train hasn't stopped at the station yet.

The agency-level review wrapped March 12, polling "go" to proceed toward launch. The SLS-Orion stack rolls to pad 39B around March 19 for final preparations, targeting a 6:24 p.m. ET launch window April 1 with backups through April 30.

Four astronauts will fly the 10-day mission: NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, joined by Canadian Space Agency astronaut Jeremy Hansen. This crew will be the first to fly an Orion spacecraft — named "Integrity" — around the Moon and back. First human lunar flyby in over 50 years.

Isaacman sat down with Spaceflight Now at Kennedy Space Center the same week, roughly two weeks after he announced a major Artemis overhaul. The February restructure shifted Artemis 3 from a lunar landing to an Earth-orbit rendezvous and systems test, with actual moon landings pushed to 2028 pending lander readiness.

That overhaul arrived after a sharply-worded NASA Office of Inspector General report released March 10. The OIG found "gaps" in the agency's approach to managing lunar lander risks, particularly around testing posture and crew survival analyses for SpaceX's Starship HLS and Blue Origin's Blue Moon. The report flagged Starship's 171-foot height — roughly a 14-story building — poses a tipping risk on lunar slopes exceeding 8 degrees. It also noted NASA lacks rescue capability for stranded Artemis crews, a problem dating back to Apollo.

"We didn't have the flight experience from Artemis 1," Isaacman told SpaceNews, referencing that the uncrewed mission didn't test the full environmental control and life support system Artemis 2 requires. "Everything that has changed, either because it's a new implementation or a change for the better, we want to double- and triple-check."

The NASA Administrator also acknowledged a deeper problem: the agency has outsourced or lost core competencies in areas like launch operations, mission control, and flight test programs. Roughly 75% of the NASA workforce is contractors. The workforce dropped from 18,000 to 14,000 civil servants in recent years.

"We've got to look at that," Isaacman said. "There has to be certain expertise relevant to our mission that we retain inside the organization."

As for what's next — Isaacman told Spaceflight Now more program updates are coming. Given the pace of changes since he took the job in late December, nobody's betting against him.
