KENNEDY SPACE CENTER, FLA. - At NASA's Space Launch Complex 2 (SLC-2), Vandenberg Air Force Base, Calif., the launch tower has been rolled back to reveal a Delta II rocket with its solid rocket boosters attached. The rocket will carry the ICESat and CHIPSat satellites into Earth orbits. The Ice, Cloud, and Land Elevation Satellite, or ICESat, is a 661-pound satellite known as Geoscience Laser Altimeter System (GLAS) that will revolutionize our understanding of ice and its role in global climate change and how we protect and understand our home planet. It will help scientists determine if the global sea level is rising or falling. It will look at the ice sheets that blanket the Earth's poles to see if they are growing or shrinking. It will assist in developing an understanding of how changes in the Earth's atmosphere and climate effect polar ice masses and global sea level. The Cosmic Hot Interstellar Plasma Spectrometer, or CHIPSat, a suitcase-size 131-pound satellite, will provide invaluable information into the origin, physical processes and properties of the hot gas contained in the interstellar medium. This can provide important clues about the formation and evolution of galaxies since the interstellar medium literally contains the seeds of future stars. The Delta II launch is scheduled for Jan. 11, 2003, between 4:45 p.m. - 5:30 p.m. PST.
