SpaceX’s Cargo Dragon spacecraft, closing out a month-long mission, is scheduled to undock from the International Space Station Sunday after a two-delay in its departure to wait for better weather in the capsule’s recovery zone off the coast of Florida.

The gumdrop-shaped cargo freighter will undock from the station’s Harmony module at 10:40 a.m. EDT (1540 GMT) Sunday. A series of departure maneuvers using the ship’s Draco thrusters will guide Dragon away from the complex, setting up for a deorbit burn Monday afternoon to allow the spacecraft to drop out of orbit and re-enter the atmosphere.

Splashdown in the Gulf of Mexico off the coast of Panama City, Florida, is scheduled for around 4:05 p.m. EDT (2105 GMT) Monday. Four main parachutes will slow the capsule before reaching the ocean, where a SpaceX recovery vessel will be in position to raise the Dragon spacecraft from the sea.

Time-sensitive cargo, such as biological research samples, will be flown back to Kennedy Space Center by helicopter, where NASA researchers will receive and catalog the materials for analysis and distribution to scientists around the world.

The undocking and splashdown will complete SpaceX’s 24th resupply mission to the space station since 2012 under the umbrella of two multibillion-dollar commercial contracts with NASA.

The Dragon spacecraft is packed with more than 4,900 pounds (2,200 kilograms) of cargo, including a spacesuit coming back to Earth for refurbishment after supporting spacewalks outside the space station.

The mission launched Dec. 21 from NASA’s Kennedy Space Center in Florida atop a Falcon 9 rocket. The Dragon cargo freighter docked with the space station Dec. 22, and astronauts began unpacking science experiments, holiday gifts and food, spare parts and other supplies.

The seven astronauts on the space station replaced the cargo with materials tagged for return to Earth ahead of the mission’s undocking and re-entry this week.
