CNN —After years of delays and a dizzying array of setbacks during test flights, Boeing’s Starliner spacecraft is finally set to make its inaugural crewed launch. “This is history in the making,” NASA Administrator Bill Nelson said of the upcoming Starliner mission during a March 22 news conference. Missteps riddled a Starliner test flight the prior year, leaving NASA and Boeing officials scrambling to figure out what went wrong. SpaceX’s Crew Dragon has been flying routine trips ever since, carrying NASA astronauts and even paying customers and tourists. On May’s inaugural crewed flight, Boeing will instead use a “perfectly acceptable mitigation” that should prevent the valves from sticking, Nappi said in March.
