VANDENBERG AFB, Calif. – A truck moves the first stage booster of a United Launch Alliance Atlas V to Space Launch Complex-3E at Vandenberg Air Force Base, Calif. in preparation for the launch of the Landsat Data Continuity Mission. The Landsat Data Continuity Mission, or LDCM, is the future of Landsat satellites. It will continue to obtain valuable data and imagery to be used in agriculture, education, business, science, and government. The Landsat Program provides repetitive acquisition of high resolution multispectral data of the Earth's surface on a global basis. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value. Launch is planned for Feb. 2013. Photo credit: NASA/Roy Allison

VANDENBERG AIR FORCE BASE, CALIF. - At Vandenberg AFB, Calif., a solar array is installed on the SciSat-1 spacecraft. The SciSat-1 weighs approximately 330 pounds and after launch will be placed in a 400-mile-high polar orbit to investigate processes that control the distribution of ozone in the upper atmosphere. The data from the satellite will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policymakers assess existing environmental policy and develop protective measures for improving the health of our atmosphere, preventing further ozone depletion. The mission is designed to last two years.

VANDENBERG AFB, Calif. -- A Boeing Delta II rocket soars above the clouds here today at Vandenberg AFB, Calif. The NASA payloads aboard the rocket are the ICESat, an Ice Cloud and land Elevation Satellite, and CHIPSat, a Cosmic Hot Interstellar Plasma Spectrometer. ICESat, a 661-pound satellite, is a benchmark satellite for the Earth Observing System that will help scientists determine if the global sea level is rising or falling. It will observe the ice sheets that blanket the Earth’s poles to determine if they are growing or shrinking. It will assist in developing an understanding of how changes in the Earth’s atmosphere and climate affect polar ice masses and global sea level. The Geoscience Laser Altimeter System is the sole instrument on the satellite. CHIPSat, a suitcase-size 131-pound satellite, will provide information about the origin, physical processes and properties of the hot gas contained in the interstellar medium. This launch marks the first Delta from Vandenberg this year. (USAF photo by: SSgt. Lee A Osberry Jr.)
