CloudSat is a Passivated NASA Earth observation satellite, which was launched on a Delta II rocket on April 28, 2006, and is awaiting disposal. It used radar to measure the altitude and properties of clouds, adding to the information on the relationship between clouds and climate to help resolve questions about global warming.[2]

It operated in daytime-only operations from 2011 to 2023 due to battery malfunction, requiring sunlight to power the radar. On December 20, 2023, the Cloud Profiling Radar was deactivated for the final time, ending the data collection portion of the mission.

The mission was selected under NASA's Earth System Science Pathfinder program in 1999. Ball Aerospace & Technologies Corp. in Boulder, Colorado, designed and built the spacecraft.

CloudSat's primary mission was scheduled to continue for 22 months to allow more than one seasonal cycle to be observed.
