Kosmos 1867 (Russian: Космос 1867) is a radar ocean reconnaissance satellite (RORSAT) that was launched by the Soviet Union July 10, 1987. It was put into a high orbit about 800 km (500 mi) from the Earth's surface. Its mission was monitoring the oceans for naval and merchant vessels. It had a mission life of about eleven months. It was powered by a nuclear reactor.
Kosmos 1867 was launched on July 10, 1987 on a Tsyklon-2 rocket from the Baikonur Cosmodrome. It was put into an orbit about 800 km (500 mi) above the Earth's surface at an inclination of 65° and a period of 100.8 minutes. Its NSSDC ID is 1987-060A, and its NORAD ID is 18187. The satellite had a mission life of about 11 months.
The satellite was powered by TOPAZ 1 nuclear reactor. This was cooled by liquid sodium-potassium, NaK, metal, it uses a high-temperature moderator containing hydrogen and highly enriched fuel. It produces electricity using a thermionic converter. It had a Plazma-2 SPT electric engine.
Kosmos 1805 (Russian: Космос 1805 meaning Cosmos 1805) was a Soviet electronic intelligence satellite which was launched in 1986. The first of four Tselina-R satellites to fly, it was constructed by Yuzhnoye with its ELINT payload manufactured by TsNII-108 GKRE. Since it ceased operations it has remained in orbit as space junk, and in April 2012 NASA's Fermi Gamma-ray Space Telescope was forced to manoeuvre to avoid a collision with the derelict satellite.
Kosmos 1805 was launched at 07:30 UTC on December 10, 1986 atop a Tsyklon-3 rocket flying from Site 32/2 at the Plesetsk Cosmodrome. Following its successful launch, the satellite was given its Kosmos designation, along with international designator 1986-097A, and Satellite Catalog Number 17191. By 9 January 1987, the satellite was in an orbit with a perigee of 634 kilometres (394 mi), an apogee of 662 kilometres (411 mi), 82.5 degrees of inclination, and an orbital period of 97.68 minutes.
On April 30, 2013, it was announced that Fermi space observatory narrowly avoided a collision with Kosmos 1805 one year previous, in April 2012. Orbital predictions several days earlier indicated that the two satellites were expected to occupy the same point in space within 30 milliseconds of each other. On April 3, 2012 telescope operators decided to stow the satellite's high-gain parabolic antenna, rotate the solar panels out of the way and to fire Fermi's rocket thrusters for one second to move it out of the way. Even though the thrusters had been idle since the telescope had been placed in orbit nearly five years earlier, they worked correctly. After the danger was past, Fermi initiated a one second thruster burn to return to position.
