MSTI-1

Re-entered 18 Jul 1993

MSTI-1 (NORAD 22229, COSPAR 1992-078A) was a US satellite that re-entered Earth's atmosphere on 18 Jul 1993, launched on 21 Nov 1992 on the MSTI-1 mission. It was operated by AFPLH / SDIO as part of the MSTI programme. The spacecraft was built by JPL/SPA on the SA-200S bus, with a mass of 147 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
