Expedition 15 was the 15th expedition to the International Space Station (ISS). Four crew members participated in the expedition, although for most of the expedition's duration only three were on the station at any one time. During Expedition 15, the ISS Integrated Truss Structure was expanded twice: STS-117 brought the S3/S4 truss, and STS-118 brought the S5 truss.

Famous quotes containing the word expedition:
“It is a sort of ranger service. Arnold’s expedition is a daily experience with these settlers. They can prove that they were out at almost any time; and I think that all the first generation of them deserve a pension more than any that went to the Mexican war.”
—Henry David Thoreau (1817–1862)
