One week after a Russian Soyuz spacecraft departed the International Space Station and brought three crew members back to Earth, another Soyuz carrying a veteran cosmonaut and a first-time NASA flight engineer is ready for launch Thursday on a quick four-orbit flight to the orbiting lab complex.

Two Russian cosmonauts used the International Space Station’s Poisk docking compartment as an airlock for the first time Wednesday in a six-hour 48-minute spacewalk to begin preparing the nearly identical Pirs module for removal next year. A new laboratory module will be parked in its place later.

An Indian Polar Satellite Launch Vehicle lifted off at 0427 GMT Thursday (11:27 p.m. EST Wednesday) with 31 satellites from nine countries, with most of the smallsats coming from U.S. customers.
