At Vandenberg Air Force Base in California, a light beam is emitted during LIDAR (LIght Detection And Ranging) laser testing on the CALIPSO spacecraft. CALIPSO stands for Cloud-Aerosol LIDAR and Infrared Pathfinder Satellite Observation. LIDAR measures distance, speed, rotation, chemical composition and concentration. CALIPSO and CloudSat will fly in formation with three other satellites in the A-train constellation to enhance understanding of our climate system. They are highly complementary satellites and together they will provide never-before-seen 3-D perspectives of how clouds and aerosols form, evolve, and affect weather and climate. Launch of CALIPSO/CloudSat aboard a Boeing Delta II rocket is scheduled for 3:01 a.m. PDT Sept. 29.
