On March 18, a capsule splashed down in the Gulf of Mexico off the coast of Florida. Two of its four passengers were Suni Williams and Barry (Butch) Wilmore.

The two NASA astronauts had launched into space 286 days earlier aboard the Boeing Starliner. Their mission? To take Starliner on its first crewed flight, a test drive to the International Space Station (ISS). But problems with the spacecraft extended their stay on the orbiting space station from one week to nine months.
