---

Resurs F-2 17F42 No. 3 was launched in Jan 1989 as Kosmos-1990. The spacecraft was reported to have imaged Armenia and other seismically active regions during its 30 day flight. On Feb 6 it lowered its perigee to only 176 km for high resolution imagery, an unprecedented orbit for a Resurs-F mission. It was recovered five days later on Feb 11.
