The International Space Station's Expedition 39 crew members spent Thursday conducting science experiments and performing routine maintenance to get their orbital home in shape for the arrival of three new crewmates. NASA astronaut Steve Swanson and Russian cosmonauts Alexander Skvortsov and Oleg Artemyev are scheduled to lift off from Baikonur at 5:17 p.m. EDT Tuesday and dock at 11:04 p.m. In this photo, Japan Aerospace Exploration Agency astronaut Koichi Wakata uses a still camera to photograph the topography of a point on Earth from a window in the cupola of the space station.
