NASA classified Starliner mishap as Type A event equivalent to Challenger and Columbia disasters
Five thrusters failed during ISS approach, causing crew to be stranded for nine months
Report identified leadership failures and decision-making issues as primary concerns
Boeing has lost over $2 billion on the fixed-price contract due to mission failure
Future crew flights are grounded until technical and cultural issues are resolved
📖 Full Retelling
NASA and Boeing faced harsh criticism in a comprehensive report released on February 20, 2026, nearly two years after the botched Starliner mission to the International Space Station, with NASA categorizing the mishap alongside the Challenger and Columbia shuttle disasters and grounding the spacecraft until dozens of corrective actions are implemented. The 311-page report classifies the 2024 crewed test mission as a Type A mishap primarily because five thrusters in the Starliner's propulsion system failed during approach to the ISS. While the crew regained control of four thrusters, NASA deemed the spacecraft unsafe for carrying astronauts home, forcing an uncrewed landing three months after docking. The two astronauts remained stranded on the station for over nine months until they could return aboard a SpaceX Dragon capsule. NASA Administrator Jared Isaacman, who took office in December, emphasized that the most troubling failure was not hardware-related but rather a breakdown in decision-making and leadership that created a culture incompatible with human spaceflight. The investigation revealed lapses in testing, reliance on previously approved designs without proper validation, and hardware operating outside qualification limits. Isaacman acknowledged that both NASA and Boeing had a bias toward proceeding with the mission that compromised safety decisions. The report reclassified the mission as Type A due to the thruster failures and financial losses exceeding $2 million, with Boeing losing over $2 billion on the fixed-price contract. NASA will not fly another crew on Starliner until technical causes are understood, the propulsion system is fully qualified, and all recommendations are implemented. Meanwhile, the agency will rely on SpaceX Dragon and Russian Soyuz flights for crew transport. Boeing has scheduled an uncrewed cargo mission for no earlier than April while implementing corrective actions and cultural changes.

The report labels the Starliner test as a Type A mishap, equating it with historic shuttle disasters, underscoring serious safety and leadership failures. This classification signals that NASA will halt crewed Starliner flights until comprehensive fixes are implemented.
Context & Background
Five Starliner thrusters failed during ISS approach
NASA leadership and decision-making were criticized
Boeing relied on previously approved designs
Crewed mission postponed return to Earth
NASA will use Dragon and Soyuz for crew transport
What Happens Next
NASA will not fly another crewed Starliner until technical causes are understood and corrected, and the propulsion system is fully qualified. An uncrewed cargo flight is planned for April, and Boeing is working on corrective actions and cultural changes to meet NASA’s safety standards.
Frequently Asked Questions
Why was the Starliner mission classified as a Type A mishap?
Because five thrusters failed, the crew was stranded, and the incident met criteria for loss of control or significant damage.
What will NASA use to transport astronauts to the ISS in the meantime?
NASA will rely on SpaceX Dragon and Russian Soyuz vehicles.
When is the next uncrewed Starliner flight scheduled?
The launch is planned for no earlier than April 2026.
How much has Boeing lost on the Starliner contract?
Boeing has incurred losses exceeding $2 billion due to the fixed-price arrangement.

NASA Blames Itself and Boeing for Botched Starliner Flight Test By Alan Boyle - February 20, 2026 01:49 AM UTC | Space Exploration In a report released nearly two years after Boeing’s botched Starliner mission to the International Space Station, NASA put the mishap in the same category as the Challenger and Columbia space shuttle disasters — and said the spacecraft wouldn’t carry another crew until dozens of corrective actions are taken. The 311-page report classifies the crewed test mission in 2024 as a Type A mishap, primarily because five of the thrusters in the Starliner spacecraft’s propulsion system failed during the capsule’s approach to the ISS . The crew was able to regain control of four of those thrusters, but NASA decided not to send astronauts back to Earth on the Starliner due to safety concerns. Instead, the craft was flown back for a landing without crew , three months after the docking. The two astronauts who rode Starliner to orbit were stuck aboard the station for more than nine months while they waited for a ride back home inside a SpaceX Dragon capsule . Today’s report faults NASA’s own leadership as well as Boeing’s team. “Starliner has design and engineering deficiencies that must be corrected, but the most troubling failure revealed by this investigation is not hardware,” NASA Administrator Jared Isaacman, who took over as the space agency’s chief in December, wrote in a letter to NASA employees that was also posted to X . “It is decision-making and leadership that, if left unchecked, could create a culture incompatible with human spaceflight.” The report documented lapses in testing the hardware in advance of Starliner’s test flights — including an uncrewed test mission to the ISS that was conducted in 2022. Engineers relied too much on designs that were previously approved for different applications, the report said. Hardware was allowed to operate outside qualification limits, and NASA managers weren’t fully aware of what was going on. “NA...
