A crew of four astronauts landed back on Earth after departing the International Space Station in NASA’s first-ever medical evacuation over an undisclosed ailment involving one of the crew members. The astronauts undocked from the station at about 5:20 p.m. New York time on Wednesday in a SpaceX Dragon capsule and splashed down off the coast of California at around 3:41 a.m. on Thursday.
