Russia Launches New Imagery Satellite

25 Nov: Russia launched a Soyuz-2-1b rocket from Plesetsk. but did not provide any description of the payload. Cataloged as Kosmos-2572, analysts initially believed it to be a new Bars-M imagery satellite. Yet there is growing evidence this is the first phase of the Razdan project. As of 3 Dec, Kosmos-2572 is in a 309 x 290 km orbit with an inclination of 96.6°. At its current altitude, Kosmos-2572 is likely capable of high resolution imagery, perhaps <0.3m. The satellite appears to be settling into its operational altitude after an

initial decrease. Launch Video.

3-5 Dec Analysis from Bart Hendrickx:

– Use of a smaller fairing on this launch points to Kosmos-2572 being a Razdan satellite with a 1.5 m mirror. There is evidence the Razdan satellite is very similar to the planned Resurs-PM — the next-generation Resurs-P satellites.

– Russia has not launched a Resurs-PM satellite, but plans to use the smaller payload fairing. If Razdan has the same design as Resurs-PM (as now looks fairly likely), it could fit inside the fairing used for the November 25 launch.

– It appears there are two phases to the Razdan program:. The first phase satellites have a 1.5 m mirror, and the second will have a 2.35 m mirror (similar to a KH-11 class spy satellite).

– There is evidence the LOMO telescope believed to be on Kosmos-2572 is very similar or identical to the 1.5 m telescope the company is building for Resurs-PM.

– The Resurs-PM project underwent significant changes in late 2018. The launch of the satellite was moved from Vostochnyy to Plesetsk, a clear sign that the project was being partially militarized.

– Resurs-PM is supposed to be placed into a circular orbit at an altitude of around 700 km (although orbits as low as 450 km are also being considered). From an altitude of 700 km, the maximum resolution of the panchromatic and multispectral channels (at nadir) are 0.4 m and 1.6 m, respectively. Assuming Razdan has the same telescope, its resolution from 300 km could be close to what is generally considered the maximum achievable theoretical resolution for a remote sensing satellite: 0.15 m.

– Resurs-PM’s optical payload is also designed to observe other orbiting satellites, so Razdan may be used for space situational awareness tasks as well.
