NASA has put the failed 2024 test flight of Boeing’s Starliner capsule in the same category as the Challenger and Columbia shuttle disasters and the Apollo 13 mission, a new report released by the agency reveals.
The space agency has classified the bungled flight, which left two NASA astronauts unexpectedly stranded in space for nine months from 2024 to 2025, as a “Type A mishap” — the most severe classification in NASA safety management.
Key to the 282-page report’s findings are criticisms of faulty engineering, lax oversight, and poor coordination between those responsible for the mission. Nonetheless, NASA has said it will continue to work with Boeing to test Starliner, with the aim of returning it to crewed flight in the coming years.
“The most troubling failure revealed by this investigation is not hardware. It’s decision-making in leadership that, if left unchecked, could create a culture incompatible with human space flight,” NASA Administrator Jared Isaacman said at a news conference today (Feb. 19). “To be clear, NASA will not fly another crew on Starliner until technical causes are understood and corrected.”
According to Isaacman (who was sworn in as NASA administrator on Dec. 17, 2025, and was not with the agency during the mission), the Starliner test should have been declared a Type A mishap as soon as it became clear that the spacecraft’s faulty thrusters put the crew in jeopardy more than a year ago. “The record is now being corrected,” he added. “There will be leadership accountability.”
Doomed from the start
Starliner’s woes began not long after it blasted off on its inaugural crewed test flight from Florida’s Cape Canaveral Space Force Station on June 5, 2024. After the spacecraft entered orbit, a number of faults appeared, including five helium leaks and five failures of the reaction control system (RCS) thrusters.
This forced engineers to troubleshoot issues from the ground. Tests conducted at Starliner’s facility in White Sands, New Mexico, revealed that during the spacecraft’s climb to the International Space Station (ISS), the Teflon seals inside the five faulty RCS thrusters likely got hot and bulged out of place and, as a result, obstructed the propellant flow, according to NASA.
NASA and Boeing’s tests ran from days, to weeks, to months, as Butch Wilmore and Suni Williams, the flight’s astronauts, remained stranded aboard the ISS.
A hot-fire test conducted while the craft was docked to the ISS on July 27, 2024, showed that the thrust was back at normal levels, but NASA engineers were still concerned that the problem could reappear during the craft’s descent back to Earth. They were also worried that the helium leaks could knock out some of the craft’s orbital maneuvering and attitude control system (OMAC) thrusters, which maintain the spacecraft on a safe flight path.
By late August, NASA announced that it planned to bring Boeing’s faulty craft back without its crew. Wilmore and Williams’ stay in space, originally scheduled to last eight days, stretched to 286 before they were retrieved by a SpaceX Dragon capsule that splashed down on March 18, 2025.
What’s next?
Boeing built the Starliner capsule as a part of NASA’s Commercial Crew Program, a partnership between the agency and private companies to ferry astronauts into low Earth orbit following the retirement of NASA’s space shuttles in 2011. As of last year, the company went roughly $2 billion into the red to address numerous setbacks in the development of Starliner.
Despite the scathing report, Isaacman said the space agency would continue to work with Boeing to fix Starliner’s issues and return it to crewed flight, adding that “America benefits by having multiple ways to take our crew and cargo to orbit.” NASA and Boeing are continuing to test Starliner’s RCS thrusters at White Sands Space Harbor in New Mexico, and they plan to launch a cargo-only Starliner mission to the ISS as soon as April.
The report comes at a time of heightened scrutiny for NASA, as the agency prepares for the launch of its crewed Artemis II mission to the moon. Boeing is the prime contractor for the core stage of the Space Launch System used in the Artemis mission, meaning it was responsible for the design, development and testing of the gigantic orange fuselage housing the engines that will give the rocket its first push into liftoff.
“Pretending unpleasant situations did not occur teaches the wrong lessons,” Isaacman said. “Failure to learn invites failure again and suggests that, in human spaceflight, failure is an option. It is not.”
