Astronaut Sunita Williams recently returned to Earth after an extended mission aboard the International Space Station (ISS). Initially planned as an eight-day mission, technical issues with Boeing’s Starliner spacecraft led to a prolonged stay of nearly nine months. Williams and her crewmate, Barry “Butch” Wilmore, were eventually brought back by a SpaceX vehicle.
During their extended mission, both astronauts conducted research, spacewalks, and maintenance tasks. Upon return, they are undergoing medical evaluations and readjusting to Earth’s gravity.
Their experience highlights the challenges and unpredictability inherent in human spaceflight, emphasizing the resilience and adaptability required of astronauts.
Why did it took them 9 months for return?
Sunita Williams and Barry “Butch” Wilmore ended up spending over nine months in space instead of the planned eight days due to technical issues with Boeing’s Starliner spacecraft. Their return was repeatedly delayed while NASA and Boeing worked to ensure a safe reentry.
- Thruster Malfunctions 🚀
- The Starliner’s thrusters showed unexpected performance degradation during docking with the International Space Station (ISS).
- NASA and Boeing needed time to analyze and troubleshoot the problem before clearing the spacecraft for a safe return.
- Helium Leaks 💨
- Several helium leaks were detected in Starliner’s propulsion system, affecting maneuverability.
- Engineers spent months assessing whether the spacecraft could still safely deorbit and land.
- Parachute Concerns 🪂
- Problems were found in Starliner’s parachute system, which is crucial for a safe landing.
- NASA required Boeing to retest and verify that the parachutes would deploy properly before approving the return.
- Backup Crew Return Options Were Limited 🚢
- Unlike SpaceX’s Crew Dragon, which has regular flights, Starliner had no backup vehicle available for an early return.
- NASA prioritized safety over speed, keeping Williams and Wilmore on the ISS until Starliner’s issues were resolved.
- Boeing & NASA Took Extra Precautions 🔍
- Starliner is still a new spacecraft, and this was only its first crewed mission.
- Engineers didn’t want to rush the return, as a failure could jeopardize the program’s future.
When Did They Finally Return?
After extensive testing and safety reviews, NASA and Boeing finally approved Starliner’s return in March 2025. Williams and Wilmore successfully landed after spending over nine months in orbit, experiencing muscle loss and difficulty adjusting to gravity upon return.
Did Boeing’s Starliner spacecraft return as well?
No, the Boeing Starliner spacecraft that transported astronauts Sunita Williams and Barry “Butch” Wilmore to the International Space Station (ISS) in June 2024 did not return with them. Due to technical issues identified during their mission, NASA and Boeing decided to send the Starliner back to Earth uncrewed to address and analyze these problems.
Consequently, Williams and Wilmore remained aboard the ISS until March 2025, when they returned to Earth aboard SpaceX’s Crew Dragon spacecraft.
