The SpaceX Crew Dragon “Endeavour” spacecraft with NASA astronauts Robert Behnken and Douglas Hurley inside undocked from the forward end of the International Space Station’s Harmony module at 7:35 p.m. EDT to complete a two-month mission.

Two very small engine burns separated Crew Dragon from the station, and the spacecraft is slowly maneuvering away from the orbital laboratory into an orbital track that will return the astronaut crew and its cargo safely to Earth.

Once flying free, Dragon Endeavour will autonomously execute four departure burns to move the spaceship away from the space station and begin the flight home.

The return timeline with approximate times in EDT is:

August 1

7:35 p.m.             Departure burn 0

7:40 p.m.             Departure burn 1

8:27 p.m.             Departure burn 2

9:14 p.m.             Departure burn 3

August 2

1:44 p.m.             Trunk jettison

1:49 p.m.             Deorbit burn

2:41 p.m.             Crew Dragon splashdown

NASA will continue to provide live coverage until astronaut Behnken and Hurley splashdown off the coast of Florida and are recovered from the Gulf of Mexico.

The duo arrived at the orbiting laboratory on May 31, following a successful launch on May 30 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. During their 63 days aboard station, Behnken and Hurley contributed more than 100 hours of time to supporting the orbiting laboratory’s investigations, participated in public engagement events, and supported four spacewalks with Behnken and Cassidy to install new batteries in the station’s power grid and upgrade other station hardware.
