NASA launches the Nimbus 6 satellite, designed to observe weather patterns from orbit and test new weather and climate detection technologies. In addition to continuing the microwave and infrared observations carried out by Nimbus 5, Nimbus 6 studies the amount of solar radiation reaching or reflected by Earth, and sends real-time observations to the experimental ATS-6 satellite, allowing NASA to test techniques and technologies that will be used in the shuttle-era TDRS (Tracking & Data Relay Satellite) system.
