Three Expedition 43 crew members are busy preparing for their homecoming during their last full day in space. Commander Terry Virts ceremoniously handed over control of the International Space Station this morning to veteran cosmonaut Gennady Padalka.
Virts and Flight Engineers Anton Shkaplerov and Samantha Cristoforetti will end their stay tomorrow at 6:20 a.m. EDT when they undock from the Rassvet module. The trio in their Soyuz TMA-15M spacecraft will parachute to a landing in Kazakhstan at 9:43 a.m. after 199 days in space. NASA TV will cover the undocking and landing activities live.
Science, the main purpose of the space station, is still ongoing today as One-Year crew member Scott Kelly collected his urine and saliva samples for the Twins study. Scientists are comparing his body in weightlessness with his Earth-bound identical twin brother and ex-astronaut Mark Kelly.
Thrusters on a Soyuz spacecraft inadvertently fired Tuesday morning momentarily changing the station’s orientation. Russian flight controllers quickly corrected the situation and the crew was never in any danger nor is there any impact on the Expedition 43 undocking Thursday morning.
