Packed safely in a custom-built, pressurized shipping container, NASA�s New Horizons spacecraft is loaded into a C-17 cargo plane at Andrews Air Force Base, Md. , for the flight to Kennedy Space Center , Fla. , on Sept. 23. The spacecraft arrived at KSC early the next morning, and is undergoing final preparations for its scheduled January 2006 launch toward Pluto and the Kuiper Belt.

NASA's New Horizons spacecraft arrived at the Kennedy Space Center, Florida on Saturday for final preparations and testing for the probe's decade-long journey. It will be the first spacecraft to visit Pluto and its moon Charon.

New Horizons arrived at Kennedy's Shuttle Landing Facility aboard a U.S. Air Force C-17 cargo plane and was moved to a clean room for processing and testing. It is scheduled to launch on a Lockheed Martin Atlas V rocket in January 2006.

New Horizons recently completed four months of space- environment tests at NASA's Goddard Space Flight Center, Greenbelt, Md., and the John Hopkins University Applied Physics Laboratory, Laurel, Md., where it was designed and built.

Carrying seven scientific instruments the compact, nearly 1,000 pound probe will fly by Pluto and Charon as early as summer 2015. Its mission is to characterize the global geology and geomorphology of the bodies, map their surface compositions, record temperatures, and examine Pluto's complex atmosphere. Fly bys of ancient rocky objects farther out in the solar system may be undertaken during an extended mission.

In October New Horizons will undergo a series of functional tests, readiness checks, and an "end-to-end" test with the tracking facilities of NASA's Deep Space Network. In November, hydrazine fuel for attitude control and course correction maneuvers will be loaded, and the spacecraft will undergo a final spin-balance test.

At the Atlas Space Operations Center on Cape Canaveral Air Force Station, processing is underway on the Atlas V. Stacking of the vehicle at Launch Complex 41 begins in early October and will be completed late that month or in early November. A launch countdown rehearsal will be performed in November. In December, the flight-ready spacecraft will be transported to the launch pad for hoisting on to the Atlas V.

Following final launch approval, liftoff is scheduled for Jan. 11, 2006, during a two-hour launch window that opens at 2:07 p.m. EST. Launch windows are also available daily from Jan. 12 through Feb. 14, 2006.

New Horizons is the first mission in NASA's New Frontiers program of medium-class planetary missions. The Applied Physics Laboratory will operate the spacecraft for NASA's Science Mission Directorate. Principal investigator Alan Stern of the Southwest Research Institute, San Antonio, leads the New Horizons science and mission team. Southwest Research Institute directed the development of the mission's seven science instruments.

The National Research Council ranked the first reconnaissance of Pluto and the Kuiper Belt at the top of its priority list for planetary missions this decade. A close-up look at these mysterious bodies will provide new information about the origin and evolution of our solar system.

Hubble Makes Movie Of Neptune's Dynamic Atmosphere

Tucson AZ (SPX) Sep 02, 2005
New NASA Hubble Space Telescope images of the distant planet Neptune show a dynamic atmosphere and capture the fleeting orbits of its satellites. The images have been assembled into a time-lapse movie revealing the orbital motion of the satellites.
