A commercial Dragon cargo capsule is heading back to Earth today to conclude a 31-day stay at the International Space Station.

The automated Dragon supply ship will be released fr om the space station's Canadian-built robotic arm at 10:59 a.m. EDT (1459 GMT), around 15 minutes later than previously planned to allow for better lighting conditions.

Once Dragon flies to a safe distance from the station, the spacecraft will close the door to its guidance, navigation and control bay, then fire its Draco thrusters around 3:22 p.m. EDT (1922 GMT) for a deorbit burn to target splashdown in the Pacific Ocean.

The reusable cargo capsule will jettison its disposable trunk section to burn up in the atmosphere. The Dragon's pressurized compartment, protected by a carbon ablative heat shield, will enter the atmosphere heading northwest-to-southeast over the Pacific Ocean.

Three main parachutes will unfurl to slow the capsule for splashdown at 4:21 p.m. EDT (2021 GMT) around 300 miles (500 kilometers) southwest of Long Beach, California.

A SpaceX recovery team in the Pacific will hoist the capsule out of the water and return the craft to the Port of Los Angeles, wh ere SpaceX will hand over time-sensitive research specimens and experiments to NASA and other science teams.

The Dragon cargo capsule is packed with nearly 2,700 pounds (1,224 kilograms) of equipment for today's trip back to Earth.

SpaceX's 18th resupply mission to the space station arrived at the orbiting complex July 27, two days after launch from Cape Canaveral aboard a Falcon 9 rocket.

The automated Dragon cargo capsule delivered 5,097 pounds (2,312 kilograms) of supplies, equipment and research investigations for the station's six-person Expedition 60 crew.

The cargo load included a new $22.5 million docking adapter to accommodate arrivals of Boeing and Starliner commercial crew capsules. Two NASA astronauts helped install the new docking mechanism -- the second such adapter on the station -- during an Aug. 21 spacewalk.

The Dragon cargo capsule was detached from the space station's Harmony module at 8:25 a.m. EDT (1225 GMT) with the lab's Canadian-built robotic arm. The robot arm is scheduled to release the Dragon spacecraft at 10:59 a.m. EDT (1459 GMT), beginning a series of maneuvers by the SpaceX cargo craft to depart the vicinity of the space station and prepare for re-entry.

Ground controllers will send the command for the robotic arm to release the Dragon spacecraft, while crew members on-board the station monitor the event.

Grasped by the robotic arm, the Dragon spacecraft is at its planned release point below the space station.

Ground controllers in Houston will command the arm to release the capsule at 10:59 a.m. EDT (1459 GMT).

Astronaut Christina Koch aboard the station will stand by at a communications panel and a robotic arm control console inside the lab's cupola module to issue commands to Dragon, or take charge of the arm if necessary.

The crew will monitor the spacecraft until it exits the so-called keep-out sphere 200 meters (660 feet) around the space station.

Mission control in Houston is "go" for release of the Dragon spacecraft.

Dragon is now flying on its own, having been released from the grasp of the space station robotic arm at 10:59 a.m. EDT (1459 GMT) as the craft flew at an altitude of around 256 miles over the Pacific Ocean.

The robotic arm has backed away to a distance of more than 10 feet. The first of three rocket burns to guide Dragon away from the space station is complete.

The Dragon spacecraft has finished its second departure burn. A yaw maneuver is coming up next, then a final departure maneuver is planned in about seven minutes.

SpaceX Dragon Released from Station for Earth Return

The SpaceX Dragon resupply ship is pictured attached to the International Space Station's Harmony module on Aug. 13, 2019, as the orbital complex flew 260 miles above the Nile River Delta in Egypt.

The SpaceX Dragon cargo spacecraft released from the International Space Station at 10:59 a.m. EDT after flight controllers in Houston delivered remote commands to the station's Canadarm2 robotic arm. Expedition 60 Flight Engineer Christina Koch of NASA monitored Dragon's systems as it departed the microgravity laboratory.

Next up, Dragon will fire its thrusters to move a safe distance from the station and execute a deorbit burn around 3:22 p.m. to leave orbit. Splashdown down is targeted for 4:21 p.m. EDT (1:21 p.m. PDT).
