SpaceX and NASA successfully launched a rocket into space on Saturday.
Two NASA astronauts, Doug Hurley and Bob Behnken, took off from Florida - the first spaceflight to take off from the US in nine years.
The mission's first launch try on Wednesday was called off with less than 17 minutes remaining on the countdown clock due to stormy weather around the Kennedy Space Center at Cape Canaveral.
Everything went to plan and Saturday and it will take the rocket 19 hours to reach the International Space Station (ISS) from the Kennedy Space Center.
It marks the first time that commercially developed space vehicles - owned and operated by a private entity rather than the US space agency - have carried Americans into orbit.
President Donald Trump arrived at the viewing platform for the launch.
