NEW YORK—Two veteran NASA astronauts, Butch Wilmore and Suni Williams, embarked on a test drive of Boeing’s new capsule with the expectation of returning home from the International Space Station within a week. However, three weeks have passed, and their flight home has been put on hold as NASA and Boeing address equipment issues that arose during their journey.
Despite three postponed landing dates, Boeing reassured that the astronauts are not stranded and that the capsule’s problems do not pose a concern for the return trip. This delayed test flight, the first with astronauts on board, aims to eventually join SpaceX in transporting crews to and from the space station for NASA.
Here is an overview of the reasons behind the extended stay:
Why was the Starliner Return Trip Postponed?
NASA requires additional time to investigate problems in the spacecraft’s propulsion system used for maneuvering in flight. The propulsion system, which is not recovered for inspection upon reentry, was identified as a key area of concern. Boeing stated that they are taking the extra time to review all data and gather insights while the service module is still in orbit.
In addition, NASA cited a desire to avoid conflicts with spacewalks as another reason for the postponement. A recent spacewalk was canceled after a water leak occurred in an astronaut’s spacesuit while inside the orbiting lab.
What Are the Problems Being Investigated?
During docking, five of the capsule’s 28 thrusters experienced issues, with all but one being restarted. Officials believe that the thruster shutdown was caused by excessive heat generated during docking. A small helium leak was detected upon launch, with four more leaks appearing by the time the capsule reached the space station. The leaks, attributed to a faulty rubber seal, are stable and not considered a significant concern for the return trip.
What’s Next?
Boeing and NASA plan to determine new landing dates once ongoing spacewalks are completed. The capsule has the capability to remain at the space station for 45 days or longer if necessary. Mission managers are diligently working to address the thruster and helium leak issues before the next flight.
In the meantime, Butch Wilmore and Suni Williams are assisting with tasks and research at the space station while also conducting system checks on the Boeing capsule. NASA emphasized that there is no rush for the astronauts to depart, as ample supplies are available for both the crew members and residents at the space station.
