Orbiting Vehicle 1-5 (also known as OV1-5) was launched 30 Mar 1966, and was the fifth satellite (and third successful satellite) in the OV1 series of the United States Air Force's Orbiting Vehicle program. OV1-5 conducted optical experiments, surveying the Earth in the infrared spectrum to see if water, land, mountains and deserts could be distinguished by their thermal gradients. It was launched concurrently with OV1-4 in the first ever side-by-side satellite orbital deployment.
