Russia Launches 4 Satellites

5 Feb: Russia launched a Soyuz 2.1v with a Volga upper (3rd) stage from Plesetsk. On board were three satellites which US Space Command has labeled Cosmos 2581, 2582 and 2583 (62902-62904).

5 Feb: Russia launched a Soyuz 2.1v with a Volga upper (3rd) stage from Plesetsk. On board were three satellites which US Space Command has labeled Cosmos 2581, 2582 and 2583 (62902-62904). Russia has released no information regarding the mission of these satellites other than to say they were launched for the Ministry of Defense.

Launch Video.

-The satellites are all co-planar with an inclination of 82.0°. Initial average altitude for all three satellites was ~587km.

  • Two of the three satellites have increased their average altitude. Cosmos 2581 raised its orbit 2.3km to 588.7km and Cosmos 2582 raised its orbit 2.8km to 589.4km. Cosmos 2583 has not maneuvered thus far and its average altitude remains 588km as of 22 Feb.

-Per Bart Hendrycx:

  • The amount of information released by the Russians has moved one more level down. All we got was a terse announcement from the Ministry of Defense on the fact that the launch had taken place and a note on the Roscosmos website that they had been successfully placed into orbit.
  • The Volga (upper stage) has so far not demonstrated the capability of deploying multiple satellites into different orbits. It usually performs a single burn to place the payload into its final orbit (within about 1 to 2 hours after launch) and then coasts for several hours until its orbit takes it over the disposal zone in the Pacific.
