SpaceX Dragon Could Rescue Stranded Astronauts on ISS

NASA has created a contingency plan to use a SpaceX Dragon spacecraft to return two astronauts who have been stranded aboard the International Space Station (ISS) due to a malfunction with Boeing's Starliner spacecraft. Following the failed CST-100 Starliner mission that launched on June 5, astronauts Suni Williams and Butch Wilmore's planned eight-day stay extended into two months as technical issues were investigated. NASA has set up modifications to a Crew Dragon spacecraft while remaining cautious about the situation, hinting that a final decision will be made soon regarding how to safely return the astronauts to Earth. There are concerns about the failure of the Starliner's propulsion system, specifically issues with its thrusters which led to the journey complications.

The Boeing Starliner encountered issues with its reaction control system thrusters, which are essential for maintaining the spacecraft's orientation in space. There were also problems with helium fuel escaping from the system, suspected to be related to swollen teflon seals blocking propellant flow.

The CST-100 Starliner is part of NASA's Commercial Crew Program, aimed at developing safe and efficient spacecraft to transport astronauts to the ISS. This program also includes SpaceX's Crew Dragon spacecraft, which has already flown several successful missions. The ongoing issues with the Starliner not only pose immediate risks for the stranded astronauts but also impact Boeing's reputation and future missions within the program.
