The STS-115 crew delivered and installed the P3/P4 truss structure on the International Space Station. Three spacewalks were carried out to put the new P3/P4 truss in service. Spacewalkers Joe Tanner, Heidemarie Stefanyshyn-Piper, Dan Burbank and Steve MacLean connected power cables and activated gear readying the P3/P4 and its unfurled solar arrays for power generation.

The STS-115 and Expedition 13 crews utilized both shuttle and station robotic arms, Canadarm and Canadarm2, during installation activities. After two return to flight missions, STS-115 represents a return to major assembly of the International Space Station.
