VANDENBERG AIR FORCE BASE, Calif. – A prelaunch news conference is held on North Vandenberg Air Force Base to present the latest information about the Ocean Surface Topography Mission, or OSTM/Jason 2. Seated from left are the moderator George Diller; Steve Neeck, OSTM/Jason 2 program executive; Omar Baez, NASA launch director at NASA's Kennedy Space Center; Kris Walsh, director of NASA and commercial programs for, United Launch Alliance; Parag Vaze, OSTM/Jason 2 project manager at the NASA's Jet Propulsion Laboratory; and Capt. Andrew M. Frey, launch weather officer with the 30th Weather Squadron. The OSTM/Jason 2 satellite will embark on a globe-circling voyage to continue charting sea level, a vital indicator of global climate change. The mission will return a vast amount of new data that will improve weather, climate and ocean forecasts. OSTM/Jason 2's expected lifetime of at least three years will extend into the next decade the continuous record of these data started in 1992 by NASA and the French space agency Centre National d'Etudes Spatiales, or CNES, with the TOPEX/Poseidon mission. The data collection was continued by the two agencies on Jason-1 in 2001. The launch window extends from 12:46 a.m. to 12:55 a.m. PDT. The satellite will be placed in an 830-mile-high orbit at an inclination of 66 degrees after separating from the Delta II 55 minutes after liftoff.
