Lewis was an American satellite which was to have been operated by NASA as part of the Small Satellite Technology Initiative. It carried two experimental Earth imaging instruments, and an ultraviolet astronomy payload. Due to a design flaw it failed within three days of reaching orbit, before it became operational.
Lewis was a 288 kilograms (635 lb) spacecraft, which was designed to operate for between one and three years.[2] It was built by TRW under a contract which was signed on 11 July 1994.[2] Its primary instruments were the Hyperspectral Imager, the Linear Etalon Imaging Spectral Array and the Ultraviolet Cosmic Background experiment.[3] A number of technology demonstration payloads were also flown.
