On June 5, astronauts Wilmore and Williams launched from Earth aboard Boeing's Starliner to the International Space Station (ISS) in the spacecraft’s first crewed mission. However, complications arose, leading NASA to overrule Boeing’s preference to utilize the Starliner for the astronauts' return journey. Instead, NASA decided to have the astronauts return on a SpaceX mission, which will not occur until a later date. Concurrently, NASA announced that the uncrewed Boeing Starliner would return to Earth on September 6, notably without astronaut Sunita Williams onboard, addressing certain health risks related to prolonged space missions, such as the "chicken legs syndrome" experienced by stranded astronauts.
