A Space Program in Limbo
Boeing’s Starliner capsule was supposed to be NASA’s reliable alternative to SpaceX – a second seat at the table for American astronauts heading to the International Space Station. Instead, the program has become a case study in how a storied aerospace contractor can stumble through years of technical setbacks, cost overruns, and eroding institutional trust, all while the clock on its NASA contract ticks louder.
When Starliner’s crewed flight test in June 2024 left astronauts Butch Wilmore and Suni Williams stranded at the ISS for months due to helium leaks and thruster failures, NASA ultimately chose to bring them home aboard a SpaceX Dragon capsule. That decision carried a weight that went far beyond logistics.
It signaled that NASA no longer fully trusted Boeing’s vehicle to safely carry humans back to Earth.
What Went Wrong – and When
The problems did not start with the June 2024 mission. Boeing’s Commercial Crew Transportation Capability contract, awarded in 2014 alongside SpaceX’s, was always expected to push the company through rigorous development. But Boeing burned through its fixed-price contract budget and absorbed billions in cost overruns from its own balance sheet – losses that quietly surpassed $1.5 billion before the crewed test flight ever launched. Software errors, valve problems, and parachute system concerns piled up across multiple uncrewed test attempts, each delay compressing the window for Boeing to prove the program’s worth.
The June mission was meant to be the moment Starliner finally turned a corner. The capsule docked successfully and the crew arrived safely – but once thruster anomalies multiplied during docking and the helium leak count grew, engineers on the ground faced a question with no clean answer: was it safe enough to fly home? Boeing maintained the vehicle was within acceptable risk margins. NASA’s own analysis disagreed. The agency’s decision to leave the capsule uncrewed for its return was not framed as a condemnation of Boeing, but that framing did little to soften the optics.
Starliner landed in New Mexico in September 2024 without its crew. Wilmore and Williams eventually returned on a SpaceX Dragon in March 2025, having spent roughly nine months aboard the ISS. The extended stay produced genuine scientific work, but the story that stuck was the one about which company’s capsule brought them home.
NASA’s Next Move and the Contract Question
NASA is currently evaluating whether to certify Starliner for regular crew rotation missions – the commercial crew flights that keep the ISS staffed. Certification requires Boeing to demonstrate that the thruster and leak issues have been resolved, not just patched for one flight. The technical bar is high, and the political and financial calculus surrounding it is even more complicated. Boeing is under pressure from investors and the aerospace industry to show Starliner can generate returns, but every additional remediation effort burns money the program has already overdrawn.
The deeper question is whether NASA needs two commercial crew providers at all, given how reliably SpaceX has performed. The rationale for a dual-provider model was sound: redundancy protects the ISS program from single-contractor failures, keeps competition alive, and distributes national aerospace capability. That reasoning has not disappeared. But maintaining that rationale costs money, and Congress and NASA leadership will have to decide whether subsidizing Boeing’s path to certification is worth the investment when SpaceX Dragon is already flying routine missions without incident.
Boeing, for its part, is navigating this pressure alongside separate crises in its commercial aviation division, where the 737 MAX continues to draw regulatory scrutiny and labor disputes disrupted production through late 2024. The company’s aerospace leadership has changed, its stock has absorbed significant losses, and its reputation with two of its most important customers – airlines and NASA – is under strain simultaneously. Starliner is not Boeing’s only problem, but it is the one most visibly connected to questions of human life and institutional credibility.
SpaceX’s Growing Grip
SpaceX does not need Boeing to fail to win this situation – it already has. Crew Dragon has completed numerous ISS rotation missions, carried private astronaut crews, and demonstrated the kind of operational reliability that NASA program managers can defend in budget hearings. The commercial crew program was designed to prevent exactly this kind of monopoly scenario, but the market and the performance record have moved in one direction. If Boeing cannot achieve Starliner certification, NASA faces the uncomfortable prospect of depending entirely on a single commercial provider for crew access to the station – a company that is also competing for Artemis lunar contracts and building its own deep-space ambitions.
Some within the space policy community have pointed to this as a structural risk worth taking seriously. A certified Starliner, even with a complicated history, would give NASA options. The agency learned the hard way after the Space Shuttle program ended that relying on a single provider – in that case, Russian Soyuz capsules – left American astronauts with very little leverage and no domestic alternative.
Boeing has indicated it intends to pursue certification and has not publicly withdrawn from the commercial crew program. But the financial reality is stark: the company has already lost money on Starliner at a scale that would have shut down a smaller contractor, and the path to recouping those losses runs entirely through NASA missions that have not yet been awarded. If NASA decides the certification risk is too high or the timeline too long, Boeing may face a choice between absorbing yet another loss to exit the program gracefully or doubling down on a vehicle whose reputation has been defined, fairly or not, by the image of two astronauts catching a ride home on a competitor’s spacecraft.
