SpaceX’s Crew Dragon capsule will depart the International Space Station and splash down in the Atlantic Ocean early tomorrow morning. It has been paired with the space station since Sunday, when it made its first docking under its own power after a successful Saturday launch atop a Falcon 9 rocket.

This final phase of the Demo-1 mission will continue studying Crew Dragon’s new build. That includes testing an upgraded parachute system to land the craft more gently than its cargo version.
