NASA astronauts still stranded on the international space station due to starliner issues.

NASA has announced that the astronauts currently aboard the International Space Station (ISS) remain stranded due to ongoing issues with Boeing’s Starliner capsule.

Background:

Butch Wilmore and Suni Williams were sent to the ISS nearly 50 days ago as part of a test mission for Boeing’s Starliner. Their mission was initially planned to last about a week, with a return scheduled for mid-June. However, the mission has been extended due to technical difficulties with the spacecraft.

Current Situation:

The Starliner capsule experienced thruster failures and helium leaks both before and after launch, leading to delays in the return of the astronauts. Engineers are still investigating the issues, and NASA has not yet provided a new return date. NASA’s commercial crew program manager, Steve Stich, stated that the team will only announce a return date when they are confident it is safe to do so.

Details on the Mission:

  • Duration: The spacecraft was initially approved for a 45-day mission. Although the astronauts have been in space longer than this, NASA has indicated that the spacecraft could potentially accommodate a stay of up to 90 days, and is approved for up to 21 days once it goes into full operational use.
  • Technical Challenges: Five thrusters failed during docking on June 6, the day after launch. Since then, four of these thrusters have been reactivated. Engineers are working to understand these failures through testing on a spare thruster in the New Mexico desert.

Alternative Plans:

While NASA aims to bring Wilmore and Williams back aboard Starliner, the space agency is also considering alternative options, which could involve using a different spacecraft if necessary.

Historical Context:

This mission marks Boeing’s first crewed test flight. In contrast, SpaceX has been successfully ferrying astronauts to the ISS since 2020 under NASA’s commercial crew program. NASA has invested billions in private companies like Boeing and SpaceX for astronaut transportation following the retirement of the space shuttles.

NASA continues to monitor the situation closely and will provide updates as new information becomes available.
