Inside the Astrotech Payload Processing Facility on Vandenberg Air Force Base in California, a worker helps secure the upper Delta Payload Attach Fitting (UDPAF) to the lower Delta Payload Attach Fitting (LDPAF). The LDPAF holds the CloudSat satellite and the UDPAF will hold the CALIPSO satellite. CALIPSO stands for Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation. CALIPSO and CloudSat are highly complementary satellites that 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. PDT Sept. 29.
