MSTI 2

MSTI 2 [BMDO]

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.

MSTI 2 failed after 5 months in orbit, possibly due to a debris collision.
