Astronaut Heidemarie M. Stefanyshyn-Piper, STS-115 mission specialist, took this self-portrait . The mission specialist had just unstowed the forward Solar Array Blanket Box (SABB) when this portrait, taken on a Sept. 12 space walk that marked the resumption of construction on the International Space Station. She shared the day's work with astronaut Joseph R. Tanner, who appears just below the glare in her helmet visor. The two 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.
