Three ISS crew, including former commander Shane Kimbrough, returned to Earth. This means NASA's female astronaut Peggy Whitson is now the commander of the space station.
Thomas Pesquet and Shane Kimbrough are currently completing the first of three scheduled spacewalks. The missions are being done to prepare the ISS for the arrival of spacecraft that will transport humans to the space station.
Two NASA astronauts completed a spacewalk last Jan. 6 to perform power upgrade on the ISS. The next spacewalk will take place on Jan. 3.
