MSTI-2

 1994-028A

---

MSTI 2 was built by Spectrum Astro for USAF Phillips Lab using the SA200S series bus. This added a hydrazine propulsion system to the MSTI-1 vehicle. The 168 kg octagonal box-shaped, 3-axis stabilized satellite was designed for theater ballistic missile acquisition and tracking, and was originally intended to watch tests of the LEAP projectile. It observed a Minuteman launch from Vandenberg in Jun 1994.
