NanoSail-D

NanoSail-D was a small satellite which was intended for use by NASA's Ames Research Center to study the deployment of a solar sail in space. It was a three-unit CubeSat measuring 30 cm × 10 cm × 10 cm (11.8 in × 3.9 in × 3.9 in), with a mass of 4 kg (8.8 lb). The satellite was lost shortly after launch due to a problem with the launch vehicle carrying it; however, a replacement, NanoSail-D2, was launched in 2010 to complete its mission.
