A Brief Photo Gallery: International Space Station's P3/P4 Truss

Five years ago today — September 9, 2006 — the Space Shuttle Atlantis launched from the Kennedy Space Center on a mission to the International Space Station.

Mission STS-115 was the latest ISS construction mission. U.S. astronauts Brent W. Jett, Jr., Christopher J. Ferguson, Heidemarie M. Stefanyshyn-Piper, Joseph R. (Joe) Tanner, and Daniel C. Burbank, along with Canadian astronaut Steven G. MacLean, installed the P3/P4 truss, a major structural element that included additional solar panel arrays.

Here’s the station before the P3/P4 truss was installed:
