Nimbus 2 (or Nimbus-C) was a meteorological satellite launched by NASA into a Sun-synchronous near-polar orbit on May 15, 1966. It was the second in a series of second-generation meteorological satellites in the Nimbus program. 

Nimbus 2 was designed to serve as a stabilized, Earth-oriented platform for the testing of advanced meteorological sensors and the collecting of meteorological data. The spacecraft carried four instruments:

• Advanced Vidicon Camera System (AVCS)
• Automatic Picture Transmission (APT)
• High-Resolution Infrared Radiometer (HRIR)
• Medium-Resolution Infrared Radiometer (MRIR)

The spacecraft and experiments performed normally after launch until July 26, 1966, when the spacecraft tape recorder failed. Its function was taken over by the HRIR tape recorder until November 15, 1966, when that also failed. Some real-time data were collected until January 17, 1969, when the spacecraft mission was terminated owing to deterioration of the horizon scanner used for Earth reference.
