A SpaceX Dragon cargo freighter will depart the International Space Station Tuesday and return to Earth, wrapping up the 20th and final visit to the orbiting research complex for the current version of SpaceX's supply ship before an upgraded Dragon starts launching later this year.

The automated Dragon supply ship will be released fr om the space station's Canadian-built robotic arm shortly after 9 a.m. EDT (1300 GMT).

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 1:58 p.m. EDT (1758 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 2:47 p.m. EDT (1847 GMT) in the Pacific Ocean southwest of Los Angeles.

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 live mice, plant cells and other biological samples.

SpaceX's 20th resupply mission to the space station arrived at the orbiting complex March 9, following a launch from Cape Canaveral aboard a Falcon 9 rocket on March 6.

The automated Dragon cargo capsule delivered 4,358 pounds (1,977 kilograms) of supplies, equipment and research investigations for the station's Expedition 62 crew.

Among the equipment delivered to the station was the European-built Bartolomeo external science platform, which was robotically installed outside the research lab's Columbus module last week.

The return of the Dragon spacecraft to Earth today marks the transition to SpaceX's next Commercial Resupply Services contract with NASA. SpaceX's following series of cargo missions will use a new Dragon spacecraft design known as the Dragon 2. Cargo flights to the space station using the Dragon 2 spacecraft are scheduled to begin in late October.

The Dragon 2's human-rated variant is named the Crew Dragon, which is scheduled to fly astronauts to the space station for the first time as soon as May.

The Dragon cargo capsule was detached from the space station's Harmony module earlier today with the lab's Canadian-built robotic arm. The robot arm is scheduled to release the Dragon spacecraft at 9:06 a.m. EDT (1306 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 9:06 a.m. EDT (1306 GMT).

Astronaut Drew Morgan 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.
