S115-E-05689 (12 Sept. 2006) --- Although no astronauts are visible in this picture, action was brisk outside the space shuttle/space station tandem when this digital still image was recorded on Sept. 12. Astronauts Joseph R. Tanner and Heidemarie M. Stefanyshyn-Piper participated in the first of three scheduled STS-115 extravehicular activity (EVA) sessions as the Atlantis astronauts and the Expedition 13 crew members join efforts this week to resume construction of the International Space Station. www.nasa.gov
