Nimbus 1

Nimbus 1 began NASA’s Nimbus meteorological research series on August 28, 1964. Its stabilized, Earth-pointing platform carried vidicon and automatic-picture-transmission cameras for daytime cloud imagery, plus a high-resolution infrared radiometer for nighttime cloud-top and surface temperatures. A short upper-stage burn left the spacecraft in an unintended eccentric orbit. The instruments nevertheless returned useful observations until September 22, 1964, when the solar paddles locked and the spacecraft could no longer generate adequate electrical power. The short science mission demonstrated day-and-night weather observation from orbit.
