Nikon NASA F4

The Nikon NASA F4 Electronic Still Camera was one of the first and rarest fully digital cameras with development started in 1987. While Nikon delivered a modified Nikon F4 body, most of the electronics for the digital camera and housings were designed and built by NASA at the Johnson Space Center and other suppliers. It was first flown in September 1991 on board the Space Shuttle Discovery, mission STS-48. Later the cameras were flown on several other Shuttle missions including STS-44, 45, 42, 49, 53, 56 and 61.
