May 1, 2021: International Space Station Configuration. Four spaceships are attached to the space station including the SpaceX Crew Dragon Endeavour, the Northrop Grumman Cygnus cargo craft, and Russia’s Soyuz MS-18 crew ship and ISS Progress 77 resupply ship.
The SpaceX Crew Dragon Resilience spacecraft with astronauts Michael Hopkins, Victor Glover, and Shannon Walker of NASA, and Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) inside undocked from the space-facing port of the International Space Station’s Harmony module at 8:35 p.m. EDT to complete a six-month science 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, Crew Dragon Resilience 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:
8:35 p.m. Departure burn 0
8:40 p.m. Departure burn 1
9:28 p.m. Departure burn 2
10:14 p.m. Departure burn 3
1:58 a.m. Trunk jettison
2:03 a.m. Deorbit burn begins
2:57 a.m. Crew Dragon splashdown
