VANDENBERG AIR FORCE BASE, Calif. -- The Aquarius_SAC-D spacecraft is secured to the Rotation and Test Fixture in cell 3 at the Spaceport Systems International payload processing facility at Vandenberg Air Force Base in California. There, the spacecraft will undergo inspection of its solar arrays and tests will be conducted on its propulsion subsystem. Further testing of the satellites various other systems will follow. Following final tests, the spacecraft will be integrated to a United Launch Alliance Delta II rocket in preparation for the targeted June launch. Aquarius, the NASA-built primary instrument on the SAC-D spacecraft, will map global changes in salinity at the ocean's surface. The three-year mission will provide new insights into how variations in ocean surface salinity relate to these fundamental climate processes. Photo credit: NASA_Randy Beaudoin, VAFB

KENNEDY SPACE CENTER, FLA. - On Launch Pad 17-B, Cape Canaveral Air Force Station, Fla., a second Solid Rocket Booster (SRB) is raised off a transporter to be lifted up the mobile service tower. It will be attached to the Boeing Delta II launch vehicle for launch of the Deep Impact spacecraft. A NASA Discovery mission, Deep Impact will probe beneath the surface of Comet Tempel 1 on July 4, 2005, when the comet is 83 million miles from Earth, and reveal the secrets of its interior. After releasing a 3- by 3-foot projectile to crash onto the surface, Deep Impact’s flyby spacecraft will collect pictures and data of how the crater forms, measuring the crater’s depth and diameter, as well as the composition of the interior of the crater and any material thrown out, and determining the changes in natural outgassing produced by the impact. It will send the data back to Earth through the antennas of the Deep Space Network. Deep Impact project management is handled by the Jet Propulsion Laboratory in Pasadena, Calif. The spacecraft is scheduled to launch Dec. 30, 2004.

NPP represents a critical first step in building the next-generation of Earth-observing satellites. NPP will carry the first of the new sensors developed for this satellite fleet, now known as the Joint Polar Satellite System (JPSS), to be launched in 2016. NPP is the bridge between NASA's Earth Observing System (EOS) satellites and the forthcoming series of JPSS satellites. The mission will test key technologies and instruments for the JPSS missions. NPP is targeted to launch Oct. 28 from Space Launch Complex-2 aboard a United Launch Alliance Delta II rocket. For more information, visit http:__www.nasa.gov_NPP. Photo credit: NASA_VAFB
