The crew aboard the International Space Station is preparing to split up while also getting ready for a U.S. space delivery.
NASA astronaut Christina Koch is packing up and cleaning her crew quarters today ahead of her return to Earth early Thursday. She will board the Soyuz MS-13 crew ship on Wednesday about 9:30 p.m. EST with crewmates Alexander Skvortsov of Roscosmos and Luca Parmitano of ESA (European Space Agency).
The trio will undock Thursday at 12:50 a.m. then parachute to a landing in Kazakhstan at 4:12 a.m. (3:12 p.m. Kazakh time). NASA TV begins its live coverage Wednesday at 9 p.m. when the departing crew says farewell to their station counterparts and closes the Soyuz hatch.
This will cap a 328-day-long mission for Koch that began on March 14. She is now in second place for the single longest spaceflight by a U.S. astronaut surpassed only by former astronaut Scott Kelly with 340 days during his final station mission.
Expedition 62 will officially begin when Koch and her Expedition 61 crewmates undock from the Poisk module. Continuing their stay in space will be Commander Oleg Skripochka of Roscosmos and NASA Flight Engineers Jessica Meir and Andrew Morgan. They will end their stay aboard the orbiting lab and return to Earth in April.
Meir and Morgan are getting ready for another mission that begins Sunday when Northrop Grumman’s Cygnus cargo craft lifts off at 5:39 p.m. It will rendezvous with the station Tuesday where the duo will be in the cupola to capture Cygnus at 3:30 a.m. with the Canadarm2 robotic arm.
Ground controllers will then remotely command the Canadarm2 to install Cygnus to the Unity module where it will stay for 90 days. Cygnus will be delivering over 8,000 pounds of new research gear and crew supplies.
