At NASA Space Launch Complex 2 on Vandenberg Air Force Base in California, the interstage for the Boeing Delta II rocket nears the top of the mobile service tower, or gantry. There it will be mated with the first stage already there. The Delta is the launch vehicle for the CALIPSO/CloudSat spacecraft. CALIPSO stands for Cloud-Aerosol Lidar & Infrared Pathfinder Satellite Observation. CALIPSO and CloudSat are highly complementary satellites and together will provide never-before-seen 3-D perspectives of how clouds and aerosols form, evolve, and affect weather and climate. CALIPSO and CloudSat will fly in formation with three other satellites in the A-train constellation to enhance understanding of our climate system. Launch of CALIPSO/CloudSat aboard a Boeing Delta II rocket is scheduled for 3:01 a.m. Sept. 29.
