WebSee the location of the International Space station, Chinese Space Station, SpaceX Starlink, and all other earth orbiting satellites. Did you know the brightest man-made object orbiting the earth is the International Space Station? And, did you know it is very easily seen on a clear night? With the Satellite Tracking application, you can determine when the space … Originally called the Molniya-2M, their development began in 1972, with launches from 1974. They were also based on the KAUR-2 bus, launching solely from Plesetsk. Earlier models were used for civilian communications in a similar orbit, but different purpose, to the military-only Molniya-1 satellites. From 1980s they were used by the military, and by the 1990s they were operated in the same manner as the Molniya 1 satellites.
