1981-093B
The final FB-1 launch carried Shi Jian 2 (Shi Jian Er Hao, PRC 9) into orbit. The satellite was also referred to as Shiyan Kexuedi Weixing (Experimental Scientific Satellite) but the SJ-2 name has been consistently used since the late 1980s. Two small subsatellites were carried into orbit with SJ-2. SJ-2 was an octagonal cylinder with 4 solar panels, 1.1m long and 1.2m diameter.
