NASA has decided to change its plans for Boeing’s Starliner spacecraft, opting to extend the stay of the two crew members on board the International Space Station and have them return on a SpaceX Dragon capsule instead. This decision comes after the discovery of thruster problems during Starliner’s trip to the space station in June. Despite wanting to complete the test flight with crew, NASA prioritized safety and opted for the safer course in light of the uncertainties surrounding the thruster issues.
Engineers determined that the thrusters on Starliner experienced overheating above designed levels, leading to Teflon seal swelling in the oxidizer lines and reduced performance. As a result, mission managers decided to extend the astronauts’ stay on the space station and have them return on a SpaceX Dragon capsule in February. The decision to switch spacecraft was the result of a spirited debate over the level of risk involved, with top managers ultimately opting for the SpaceX option.
In the coming days, NASA will conduct a rehearsal for Starliner’s undocking from the space station under remote control. The uncrewed craft will then depart, likely in early September, with a planned touchdown at White Sands Space Harbor in New Mexico. The astronauts on board will continue to assist in space station activities while awaiting their return, potentially even participating in spacewalks towards the end of their expedition. SpaceX has expressed readiness to support NASA in any way necessary during this transition.
Boeing’s forthcoming steps involve working with NASA to assess the success of the current test mission and address the thruster problems and other issues that have arisen. These assessments will help determine if Starliner needs to be redesigned or if additional test missions are required. Safety considerations will be paramount in guiding decisions about Starliner’s future, with a continued focus on crew safety and spacecraft readiness. Boeing has expressed commitment to prioritize crew and spacecraft safety and ensure a safe and successful uncrewed return for Starliner.
As NASA looks towards the future of Starliner and its role in crewed spaceflight missions, safety and operational readiness remain key priorities. NASA Administrator Bill Nelson emphasized that politics play no role in these decisions, with safety being the primary focus. He expressed confidence that the issues with Starliner will be resolved, and the spacecraft will eventually conduct regular missions with NASA astronauts on board. The extensive working relationship between NASA and Boeing, along with Boeing’s commitment to the program, are cited as reasons for optimism about Starliner’s future in spaceflight.
