The Expedition 42 crew worked Wednesday with fruit flies, a humanoid robot and a Dragon spacecraft. Also, Europe’s Automated Transfer Vehicle-5 fired its engines for nearly five minutes, slightly lowering the station’s orbit to prepare for an upcoming ISS Progress 58 resupply mission.
Commander Barry Wilmore and Italian astronaut Samantha Cristoforetti packed gear inside the SpaceX Dragon private space freighter for retrieval on Earth. The Dragon will return to Earth on Feb. 10 when it will splashdown in the Pacific Ocean for recovery off the coast of Baja California. Cristoforetti later fed fruit flies for an experiment studying their immune system as a model for a crew member’s susceptibility to disease in space.
Flight Engineer Terry Virts unpacked Robonaut in the Destiny then powered up the humanoid robot for a mobility test during the afternoon. Its legs received power for the first time Wednesday. Virts monitored the leg movements in conjunction with operators on the ground.
