Two NASA astronauts, Sunita Williams and Barry Wilmore, who have been unexpectedly stranded in space for over two months, are set to return to Earth in February 2025 aboard a SpaceX Crew Dragon spacecraft. Their original mission, which began on June 5, was intended to last just eight days but has been extended to approximately eight months due to issues with the Boeing Starliner spacecraft.
The Starliner, which experienced technical difficulties including helium leaks and malfunctioning thrusters, will not be used for the return journey. Instead, the spacecraft will return to Earth “un-crewed,” while the astronauts will make their way back on a SpaceX vehicle.
Boeing and SpaceX, both contracted by NASA for commercial space flights, have faced distinct challenges. SpaceX has successfully completed nine crewed flights and various commercial missions. In contrast, the Starliner’s debut crewed mission encountered multiple setbacks, prompting Boeing and NASA engineers to conduct extensive tests to resolve the issues.
NASA Administrator Bill Nelson highlighted the collaborative efforts to address the Starliner’s problems. “Space flight is inherently risky, and test flights are particularly so. Our foremost priority remains safety,” he stated during a recent press conference.
To facilitate the astronauts’ return, NASA has extended their stay aboard the International Space Station (ISS) until February 2025. SpaceX’s next Crew Dragon mission, initially planned for four astronauts, will now carry two additional crew members, making room for Williams and Wilmore.
Both astronauts, who have extensive experience with long-duration space missions, have agreed to the revised return plan. During their extended stay, they will continue scientific research, maintain the space station, and potentially conduct spacewalks.
Boeing, meanwhile, remains focused on ensuring the safety of its spacecraft and crew. The company has pledged to continue working towards a successful and safe return of the Starliner on its next un-crewed mission.
The delay underscores the complexities and challenges of space travel, as well as the ongoing efforts to advance spacecraft technology and ensure astronaut safety.
