What was the first digital camera in space? It turns out in 1991 NASA sent a modified Nikon F3 with small Kodak CCD sensor and external processing unit on a shuttle mission. Called the Hawkeye II, this system used a RS-232 serial port to connect to its external gear. Kodak would use this platform as the basis for the DCS system, the first commercially available digital camera. 

To put this in perspective, 1991 was the year that Linux was released, Apple released System 7 for the Mac, and the floppy disk was a popular storage device. Early limitations though didn't apply to the NASA space program. They were able to squeeze digital components into an F3 to pioneer the field of digital photography.
