Once in space, it is jettisoned. The Lockheed Martin Atlas V is the launch vehicle for the New Horizons spacecraft, which is designed to make the first reconnaissance of Pluto and Charon - a "double planet" and the last planet in our solar system to be visited by spacecraft. The mission will then visit one or more objects in the Kuiper Belt region beyond Neptune. New Horizons is scheduled to launch in January 2006, swing past Jupiter for a gravity boost and scientific studies in February or March 2007, and reach Pluto and its moon, Charon, in July 2015.

KENNEDY SPACE CENTER, FLA. - In the clean room at KSC’s Payload Hazardous Servicing Facility, the media (also dressed in clean room suits) learn about NASA’s New Horizons spacecraft (at left) from New Horizons Mission Systems Engineer David Kusnierkiewicz, in the center. Behind Kusnierkiewicz is one half of the fairing that will enclose the spacecraft for launch, scheduled for January 2006. The media event brought photographers and reporters to the site to talk with project management and test team members from NASA and the Johns Hopkins University Applied Physics Laboratory. Carrying seven scientific instruments, the compact 1,060-pound New Horizons probe will characterize the global geology and geomorphology of Pluto and its moon Charon, map their surface compositions and temperatures, and examine Pluto's complex atmosphere. After that, flybys of Kuiper Belt objects from even farther in the solar system may be undertaken in an extended mission. New Horizons is the first mission in NASA's New Frontiers program of medium-class planetary missions. The spacecraft, designed for NASA by the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., will fly by Pluto and Charon as early as summer 2015.

KENNEDY SPACE CENTER, FLA. — On Complex 41 at Cape Canaveral Air Force Station in Florida, workers move the radioisotope thermoelectric generator (RTG) into an area of the fairing containing the New Horizons spacecraft, to which it will be attached. Designed and integrated at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., New Horizons will launch on a nine-and-a-half-year voyage to Pluto. Typical of RTG-based systems, as on past outer-planet missions, New Horizons does not have a battery for storing power. At the start of the mission, the RTG, which provides power through the natural radioactive decay of plutonium dioxide fuel, will supply approximately 240 watts (at 30 volts of direct current) - the spacecraft’s shunt regulator unit maintains a steady input from the RTG and dissipates power the spacecraft cannot use at a given time. By July 2015 (the earliest Pluto encounter date) that supply decreases to 200 watts at the same voltage, so New Horizons will ease the strain on its limited power source by cycling science instruments during planetary encounters. On Complex 41 at Cape Canaveral Air Force Station in Florida, workers on the ground oversee the radioisotope thermoelectric generator (RTG) being lifted into the Vertical Integration Facility. The RTG will be installed on the New Horizons spacecraft within the fairing at the top of the Atlas V launch vehicle.
