CAPE CANAVERAL, Fla. – Spotlights illuminate the United Launch Alliance Delta II Heavy rocket that will launch NASA’s twin Gravity Recovery and Interior Laboratory (GRAIL) mission from Space Launch Complex 17B on Cape Canaveral Air Force Station in Florida. Liftoff is scheduled for 9:08:52 a.m. EDT Sept. 10. GRAIL will fly twin spacecraft in tandem around the moon to precisely measure and map variations in the moon's gravitational field. The mission will provide the most accurate global gravity field to date for any planet, including Earth. This detailed information will reveal differences in the density of the moon's crust and mantle and will help answer fundamental questions about the moon's internal structure, thermal evolution, and history of collisions with asteroids. The aim is to map the moon's gravity field so completely that future moon vehicles can safely navigate anywhere on the moon’s surface. For more information, visit http://www.nasa.gov/grail.

Letter from Frederick W. Baldwin to Alexander Graham Bell, March 6, 1915

KENNEDY SPACE CENTER, FLA. - After being raised to a vertical position, the first stage of an Atlas V rocket is being moved into the Vertical Integration Facility to begin preparations for launch on Launch Complex 41 at Cape Canaveral Air Force Station. 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.
