KENNEDY SPACE CENTER, FLA. - In the Payload Hazardous Servicing Facility, a metal canister is lowered over the radioisotope thermoelectric generator (RTG). The canister will protect the RTG while it is being moved to the RTG facility. The RTG underwent a fit check with the spacecraft. The RTG is the baseline power supply for the New Horizons, scheduled to launch in January 2006 on a journey to Pluto and its moon, Charon. As it approaches Pluto, the spacecraft will look for ultraviolet emission from Pluto's atmosphere and make the best global maps of Pluto and Charon in green, blue, red and a special wavelength that is sensitive to methane frost on the surface. It will also take spectral maps in the near infrared, telling the science team about Pluto's and Charon's surface compositions and locations and temperatures of these materials. When the spacecraft is closest to Pluto or its moon, it will take close-up pictures in both visible and near-infrared wavelengths. It is expected to reach Pluto in July 2015.
