Starliner docked to ISS.

The inspector general (IG) for NASA today released a new audit report [pdf] of the agency’s management of its manned commercial crew program, specifically looking at Boeing’s Starliner capsule and its failures. Though the IG made six recommendations, mostly about management procedures to better run the program, the first was the most important:

As the [Boeing] contract allows, defer payments, including partial or advanced payments, to Boeing for any Starliner-3 milestones until the human-rating certification of Starliner is complete.

In other words, the IG doesn’t want NASA to pay Boeing anything more. Boeing’s contract for Starliner was fixed price. It is Boeing’s responsibility to deliver the product, and until it does so NASA should lay out no more cash.

More significantly, NASA’s management immediately concurred with this recommendation.

This IG report now explains much of what happened in the past few months. In February 2026 NASA officials had indicated that the agency and Boeing were considering flying an unmanned Starliner cargo flight to ISS in April 2026. According to rumors over the past year, NASA was considering treating that mission as a cargo flight, not part of Boeing’s original Starliner fixed-price deal, and thus pay it the going rate for such a flight. That way Boeing could get Starliner certified for later manned flights, without spending more of its own money. The company was already in the hole by more than $2 billion for the project.

However, that flight never happened, and when NASA announced its ISS launch schedule for the rest of the year in May there were no Starliner missions included at all. All NASA officials would say is the cargo mission was “under review.”

Then in late May NASA announced it has awarded SpaceX new contracts for from three to six manned mission to ISS through 2030, which practically eliminated any chance Starliner would ever be used for crew flights.

During all these developments NASA officials were very coy about Starliner and its future. It was always under review, and no decision had been made about a future unmanned mission.

We now know what that “review” was. NASA inspector general was putting together this new audit report of the Starliner program, and likely advised NASA management early on that its recommendations opposed NASA paying Boeing anything further, including spending money on that unmanned cargo flight. NASA management, under Jared Isaacman, quickly recognized it could not go against this recommendation, and thus that cargo mission was canceled.

Will Boeing lay out the cash to fly another unmanned Starliner demo mission? It increasingly appears it will not. And if that is the case, it means Boeing is literally out of the business of manned space exploration. It might still have some contracts on-going (such as SLS), but as those close out, so will this company’s place in America’s space future.
