NASA is carefully evaluating options for the safe return of two astronauts currently stranded aboard the International Space Station (ISS). Astronauts Butch Wilmore and Suni Williams, who arrived at the ISS on June 6 via the Boeing Starliner spacecraft, were scheduled for an eight-day mission. However, unexpected technical issues have extended their stay indefinitely.
During the Starliner’s flight to the ISS, engineers detected anomalies in the spacecraft’s thrusters and observed several leaks in its helium system. These issues have raised concerns about the Starliner’s readiness for the return journey.
In response, NASA announced on Tuesday that it plans to conduct two comprehensive reviews before making a decision on the astronauts’ return. The Program Control Board Review and the Agency Flight Readiness Review are set to conclude by the end of August.
“Safety is our top priority,” a NASA spokesperson said. “We are thoroughly examining all aspects of the Starliner’s propulsion system to ensure a secure journey home for our astronauts.”
Engineering teams from NASA and Boeing have been conducting extensive thruster tests and in-depth data analyses to understand and resolve the spacecraft’s issues. The findings from these efforts will play a crucial role in determining the next steps.
As NASA evaluates its options, one possibility under consideration is bringing Wilmore and Williams back aboard the Starliner, should it be deemed safe. Alternatively, the astronauts could return as part of the SpaceX Crew-9 mission scheduled for early next year.
The unexpected extension of the astronauts’ mission has captured global attention, highlighting the inherent challenges and complexities of space exploration. NASA’s diligent approach underscores its commitment to astronaut safety and mission success.
