NASA astronauts Doug Hurley took over manual control of the SpaceX Crew Dragon spacecraft on Saturday, shortly after the vehicle’s historic first launch from Cape Canaveral in Florida. Crew Dragon is designed to fly entirely autonomous throughout the full duration of its missions, including automated docking, de-orbit and landing procedures, but it has manual control systems in case anything should go wrong and the astronauts have to take over. This test is the first time the manual controls have been used in space, and is a key part of certifying Crew Dragon for regularly operational human flight.

Astronaut Bob Behnken and Hurley removed their fashionable SpaceX space suits just before Hurley completed the manual maneuvers, which is also part of the plan. They’re able to go without the suits in the pressurized cabin during its transit to the ISS, only needing to put them back on for space station docking, and the interior of Crew Dragon actually provides them a fair amount of room to move around in. This also makes it easier for them to operate the spacecraft controls.
