Two Expedition 60 crewmates and a visiting astronaut are returning to Earth on Thursday. The orbiting Expedition 61 residents staying on the International Space Station will then turn their attention to a series of spacewalks set to begin this weekend.
Commander Alexey Ovchinin handed over control of the orbiting complex today to astronaut Luca Parmitano of ESA (European Space Agency) during the change of command ceremony. The Expedition 61 mission will officially begin when the three Expedition 60 crewmates depart the station.
NASA astronaut Nick Hague is returning to Earth with Ovchinin and visiting astronaut Hazzaa Ali Almansoori of the United Arab Emirates. The trio will board the Soyuz MS-12 crew ship and undock from the station’s Rassvet module on Thursday at 3:36 a.m. EDT. They will parachute to landing in Kazakhstan at 7 a.m. (5 p.m. Kazakh time).
There was still time for research today as NASA Flight Engineer Andrew Morgan took turns with Parmitano exploring cognition and motion in space. Morgan also installed the Small Optical Communication System, or SOLISS, that is testing the real-time downlink of large amounts of data from the station.
The first of five spacewalks to upgrade power systems on the orbital complex starts Sunday at 7:50 a.m. NASA astronaut Christina Koch will join Morgan and exit the station’s Quest airlock in their U.S. spacesuits to begin installing new lithium-ion batteries on the Port-6 truss structure. The duo will work outside in the vacuum of space for about six hours and 30 minutes.
