MOSCOW. July 24 (Interfax-AVN) - The spent Soviet electronics and signals intelligence satellite Cosmos-1400 (Tselina-D class) launched from Plesetsk in 1982 may fall to Earth in early September, according to the United States Space Surveillance Network data.
The tentative date when Cosmos-1400 (internationally catalogued as 1982-079A) ceases its ballistic existence and enters dense layers of the atmosphere is September 10. The information is being constantly updated.
The satellite will fall in pieces and some of its fragments may reach the Earth surface.
The satellite linear dimensions are about eight meters, the U.S. network said.
A Vostok rocket carrying Cosmos-1400 blasted off from Plesetsk on August 5, 1982. The satellite had a nearly polar orbit with an inclination of 81 degrees and an altitude of 630 to 670 kilometers.
