NASA's Boeing Starliner program has faced serious setbacks, including a mission that left two astronauts stranded on the International Space Station (ISS) for nine months. Despite thruster failures and helium leaks, NASA is giving Starliner another chance with a crewed flight planned for 2028.
What Happened to the Stranded Astronauts?
The first crewed Starliner mission, known as Crew Flight Test, launched in June 2024 with astronauts Butch Wilmore and Suni Williams. They successfully reached the ISS, but the spacecraft experienced multiple issues during the journey.
Five thrusters malfunctioned, and several helium leaks were detected in the propulsion system. NASA deemed the return trip too risky, so Starliner returned to Earth empty while the astronauts remained on the station.
Wilmore and Williams stayed on the ISS for about nine months before returning on a SpaceX Crew Dragon capsule. The extended stay was unexpected but not unprecedented in spaceflight history.
Why Did NASA Decide to Trust Starliner Again?
After such a troubled mission, many expected NASA to abandon Starliner. However, the agency has decided to proceed with another crewed flight, Starliner-2, scheduled for 2028.
NASA's decision reflects its commitment to having multiple commercial crew providers. Currently, SpaceX's Crew Dragon is the only operational vehicle for transporting astronauts to and from the ISS from U.S. soil.
Having a second provider is crucial for redundancy and competition. NASA wants to avoid relying solely on one company, especially in case of technical issues or schedule delays.
What Is the Plan for Starliner-2?
Starliner-2 will be commanded by NASA astronaut Woody Hoburg. The rest of the crew has not yet been announced. The mission is targeted for mid-2028. The longer history behind the story is traced in NASA's SR-71 Blackbird Revival: What We Know So Far.
Before the crewed flight, Boeing will conduct an uncrewed test flight to demonstrate that the fixes to the thrusters and helium leaks are effective. This test is a critical milestone for certifying Starliner for regular crew rotations. The background to this story is set out in Spacecraft Rescue Mission for NASA Telescope Fails.

Earlier coverage in Nasa Eclipse Air Mission: Rare Data Capture Over Iceland shows how the argument developed.
Key Takeaways from the Starliner Saga
- Starliner's first crewed mission faced thruster failures and helium leaks, leading to a nine-month extended stay for two astronauts.
- NASA still plans to fly Starliner-2 with a crew in 2028, pending an uncrewed test flight.
- The decision ensures redundancy in commercial crew transportation to the ISS.
- Boeing must resolve technical issues to regain full certification.
- Astronaut safety remains the top priority in all missions.
Starliner vs. Crew Dragon: A Comparison
| Feature | Boeing Starliner | SpaceX Crew Dragon |
|---|---|---|
| First crewed flight | 2024 (Crew Flight Test) | 2020 (Demo-2) |
| Issues on first crewed flight | Thruster failures, helium leaks | None major |
| Operational status | Under development | Operational |
| Next crewed mission | Starliner-2 (2028) | Ongoing rotations |
What to Watch Next
The uncrewed test flight will be a crucial test for Boeing. If successful, NASA will proceed with Starliner-2. Any further issues could delay the program or even lead to its cancellation.

FAQ
Why were the astronauts stranded for nine months?
NASA decided that the Starliner spacecraft was not safe enough to return the astronauts due to thruster malfunctions and helium leaks. They returned on a SpaceX Crew Dragon instead.
Will Starliner fly again with astronauts?
Yes, NASA plans to launch Starliner-2 with a crew in 2028, commanded by Woody Hoburg. An uncrewed test flight will precede it.
What caused the Starliner problems?
The exact causes are still under investigation, but the issues involved thruster failures and helium leaks in the propulsion system. Boeing is working on fixes.
Is SpaceX still involved in crewed spaceflight?
Yes, SpaceX's Crew Dragon remains operational and continues to transport astronauts to and from the ISS.
