The Soyuz-2 carrier rocket was launched from the Plesetsk cosmodrome on Wednesday
MOSCOW, July 11. /TASS/. The Russian Defense Ministry has assumed control over four satellites launched from the Plesetsk cosmodrome in the interests of the Russian military, the ministry's press service told reporters on Thursday.
"The spacecraft launched by the Aerospace Defense Forces from the State Trial Cosmodrome Plesetsk on July 10, have been delivered to the designated orbit, and the Russian Defense Ministry assumed control over the satellites," the press service said.
"Stable telemetric communication has been established and is maintained with the spacecraft. The control systems of the spacecraft are functioning in the routine mode," the press service added.
This was the second launch of the Soyuz-2 carrier rocket from the Plesetsk cosmodrome in 2019.
Soyuz-2.1v launches four experimental satellites, including a satellite inspector
On 10 July 2017, at 20:14 MSK (17:14 UTC) the Air and Space Forces successfully launched a Soyuz-2.1v launcher from the pad No. 4 of the site No. 43 of the Plesetsk launch site. The Volga booster successfully released four small satellites - Cosmos-2535, Cosmos-2536, Cosmos-2537, and Cosmos-2538. According to the ministry of defense statement, the satellites' mission is to study the effect of natural and artificial factors of space on satellites operated by Russia and to calibrate radars operated by the Air and Space Forces.
The satellites received international designations 2019-039A to 2019-039D and NORAD numbers 44421 to 44424.
Two satellites - Cosmos-2535 and Cosmos-2536 - later conducted a series of proximity maneuvers. It appears that these are objects 2019-039A/44421 and 2019-039D/44424.
This is not the first time Russia announces a launch of a satellite-inspector. In August 2017 the ministry of defense disclosed that Cosmos-2521 is a satellite-inspector launched in June 2017 along with Cosmos-2519. See a discussion of the program at the RussianSpaceWeb site.
Russia has launched its fourth Blagovest communications satellite via a Proton rocket Tuesday. Having lifted off from the Baikonur Cosmodrome at 02:56 local time (00:56 Moscow Time, 21:56 UTC on Monday), Proton’s Briz-M upper stage is now undertaking a nine-hour multiple-burn mission that will deploy its payload into geostationary orbit.
