1992-078A
MSTI 1 was built by JPL and Spectrum Astro for the USAF Phillips Lab and SDIO. The 147 kg satellite was powered by solar panels. Its primary mission was to obtain IR images of the oceans. Shortly after launch by Scout from Vandenberg in Nov 1992, a fuel leak depleted its cold gas attitude control system, and the satellite was placed in spin stabilized mode. On Dec 4 it was announced to have met its objectives, and to be continuing to collect IR data. It ceased operating in the spring of 1993 after returning 100000 exposures of the infrared background in the 4.4-4.8 micron band.
