Mike Lynch of the Johns Hopkins University Applied Physics Laboratory and Benjamin Rodriguez of the Southwest Research Institute re-install the Solar Wind Around Pluto (SWAP) instrument on NASA's New Horizons spacecraft Oct. 5 at Kennedy Space Center, Fla. SWAP, one of seven instruments on the Pluto-bound New Horizons probe, had been removed for previously planned maintenance and installation of new detectors. Visible above SWAP is the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument; to the right are the telescopic Long Range Reconnaissance Imager (LORRI) and, with protective red covers, the spacecraft's star-tracking navigation cameras.

Launch is scheduled during a 35-day window that opens on January 11, 2006.
