SpaceX’s Crew-1 capsule splashed down in the Gulf of Mexico carrying four astronauts early today, CNET reports. The Crew-1 landed just before 3 a.m. ET. It was the second time humans have returned to Earth on a SpaceX Crew Dragon capsule. “We welcome you back to planet Earth and thanks for flying SpaceX,” SpaceX’s Mission Control radioed moments after splashdown. “For those of you enrolled in our frequent flyer program, you’ve earned 68 million miles on this voyage.” The astronauts’ 167-day stay at the International Space Station was the longest for a crew launching from the U.S.
