This morning (April 9), NASA astronaut Peggy Whitson will become the first woman to twice command the International Space Station, taking command before three space fliers return to Earth. You can watch both events live here at Astronaut.com.
Whitson became the first female space station commander during Expedition 16 in 2008, and she will step back into that role today at 10:40 a.m. EDT (1440 GMT) during a change-of-command ceremony. In between, there has been one other female space station commander, Sunita Williams. Whitson will take over from NASA astronaut Shane Kimbrough, who is about to depart the station.

At 4 a.m. EDT (0800 GMT), the Soyuz spacecraft will undock from the station, and at 6:27 a.m. EDT (1027 GMT), the Russian craft will perform a de-orbit burn and finally land in Kazakhstan at 7:20 a.m. EDT (1120 GMT).
