MSTI 2 (Miniature Sensor Technology Integration 2) was a US Department of Defense spacecraft launched from the Vandenberg AFB by a Scout-G1 rocket. It was the last of the now discontinued Scout series. The primary mission of MSTI 2 was to demonstrate theater ballistic missile (TBM) tracking and was intended to last for six months. It successfully spotted and locked onto a test Minuteman-3 launched from Vandenberg AFB. More than three million short wavelength infrared (SWIR) and medium wavelength infrared (MWIR) image frames were obtained during the mission.
The Scout family of rockets were were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages.
