Three Expedition 54 crew members are going into the weekend packing up and preparing to return to Earth on Tuesday. Commander Alexander Misurkin will lead fellow crew members Joe Acaba and Mark Vande Hei back to Earth inside the Soyuz MS-06 spacecraft Tuesday for a landing in south central Kazakhstan at 9:31 p.m. EST.
NASA TV will broadcast live all of the departure activities on Monday and Tuesday. The Change of Command Ceremony begins Monday at 2:40 p.m. when Misurkin hands over station control to cosmonaut Anton Shkaplerov. The new commander will stay behind with Flight Engineers Scott Tingle of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency and become Expedition 55 when their crewmates undock the next day.
The departing trio will say farewell Tuesday and close the Soyuz hatch at 2:15 p.m. They will undock from the Poisk module at 6:08 p.m. signifying the start of Expedition 55 and the end of Expedition 54. Next, the Soyuz engines will fire one last time at 8:38 p.m. sending the crew back into Earth’s atmosphere for a parachuted landing in Kazakhstan at 9:31 p.m.
The trio will have spent 168 days in space, orbiting Earth 2,688 times, conducted dozens of science experiments and seen the departure and arrival of eight different space ships. The departing crew members will also go home as experienced spacewalkers. Misurkin and Acaba each conducted one spacewalk and Vande Hei conducted four spacewalks during their five-and-half month stay in space.
