Applications Technology Satellite 3, or ATS-3, was a long-lived American experimental geostationary weather and communications satellite, operated by NASA from 1967 to 2001.[3] It was at one time reputed to be the oldest satellite still in operation.[4] As of 1995, NASA referred to the ATS-3 as "The oldest active communications satellite by a wide margin."[5]

On November 10, 1967, ATS-3 took NASA's first color photo (digital image mosaic) of the full-disk Earth, which was subsequently used on the cover of the first Whole Earth Catalog.
