Astronauts Sunita Williams and Butch Wilmore have now spent nearly 70 days aboard the International Space Station, a duration nearly ten times longer than initially planned for their test flight. This extended stay is the result of ongoing technical difficulties with the Boeing Starliner spacecraft, which encountered issues with its reaction control thrusters during its initial docking attempt on June 6. As engineers work to resolve these critical problems, the astronauts’ return to Earth remains uncertain, adding complexity to NASA’s mission timeline.
Astronauts’ Space Suits Not Suitable
NASA officials revealed that the astronauts’ space suits are not suitable for the alternative spacecraft that could be used if the Starliner is deemed unsafe. The astronauts, Suni Williams and Butch Wilmore, are “doing great” and were prepared for a risky mission.
Issues with the Starliner Mission
Williams and Wilmore traveled to the International Space Station (ISS) on June 5, expecting to return after eight days. However, the Starliner spacecraft encountered problems: five of its thrusters failed, and there was a helium gas leak affecting the propulsion system.
Options for Returning Home
Due to the issues, Williams and Wilmore must stay on the ISS while engineers review the situation. They may return using a SpaceX spacecraft either in autumn or early next year. Returning on the earlier SpaceX flight without proper suits could pose risks, while traveling on the later flight would give time to provide the appropriate suits.
Boeing’s Confidence and NASA’s Concerns
Boeing insists its Starliner spacecraft can safely bring the astronauts home. However, NASA has not provided details on what would reassure them about the Starliner’s safety. They have brought in external experts to analyze the data and continue their review.
Potential Embarrassment for Boeing
If the astronauts are forced to return on a SpaceX craft, it could be a significant embarrassment for Boeing, as this is their first crewed mission attempt, while SpaceX has already completed nine crewed flights for NASA.
NASA will continue to analyze the Starliner’s performance and make a decision by the end of August. The agency has assured that Starliner could still be used in an emergency, but they are exploring all options to ensure a safe return for the astronauts.
