CloudSat, part of a multi-satellite, multi-sensor National Aeronautics and Space Administration (NASA) experiment designed to measure the properties of clouds, successfully concluded its final environmental test and was mated to the flight adapter interface in preparation for launch. The spacecraft previously completed thermal vacuum, electromagnetic conductance, electromagnetic interference, vibration, shock and acoustic testing. Ball Aerospace & Technologies Corp. built CloudSat and was responsible for the testing and integration of the spacecraft’s payload. It will also perform CloudSat’s launch operations and initial in-orbit commissioning. The company did not say when the satellite is scheduled to launch.
