1976-091A
The Block 5D-1 F-1 satellite, DMSP 12535, was launched on 1976 Sep 11 from SLC10W at Vandenberg. The spacecraft separated from the Thor DSV-2U (USAF designation LV-2F) and the first of two solid stages ignited (administratively the upper stages were considered part of the payload, not the launch vehicle). The second stage was a Star 37XE, a modified version of the TE-M-364-4 used in Burner 2. The third stage was a further modified version of the same motor, the Star 37S. The Star 37XE placed the DMSP/Star 37S in a suborbital transfer trajectory, and the Star 37S burned at apogee to circularize the orbit. The Star 37S remained attached, but a number of small pieces of debris were cataloged which are thought to be sensor covers.
