A Russian Soyuz booster climbed into orbit Monday with a U.S. Army colonel, a veteran Russian cosmonaut and a Canadian flight engineer, kicking off a six-hour chase of the International Space Station.

Orbital ATK readied an upgraded Antares rocket for launch Monday from Wallops Island, Va., to deliver more than 3 tons of crew supplies, science gear, spare parts and three small satellites to the International Space Station to test miniaturized, low-cost technologies for Earth observation applications.

NASA and Roscosmos, the Russian space agency, have agreed to extend astronaut Peggy Whitson’s stay aboard the International Space Station by three months to enable uninterrupted research aboard the orbital laboratory during a period when Russia is temporarily reducing its crew complement, the U.S. space agency said Wednesday.
