Photos: Atlas 5 rocket aims for International Space Station

Shane Kimbrough and Peggy Whitson, setting a new record as the world’s most experienced female spacewalker, floated outside the International Space Station Thursday and continued work to set up a second docking port for U.S. crew ferry ships. They also installed an upgraded computer relay box and protective shielding before calling it a day.

Three Chinese military surveillance spacecraft and an experimental nanosatellite rode a Long March 4C rocket into orbit Tuesday.

A commercial Cygnus cargo freighter arrived at the International Space Station Tuesday two-and-a-half days after launching from Virginia’s Eastern Shore, delivering a new British-made high-speed communications antenna and more than 7,000 pounds of other experiments and equipment.
