Summary
Kosmos 2573 (Bars-M No. 5?) launched on a Russian Space Forces Soyuz 2.1b from 43/4 (43R), Plesetsk Cosmodrome, Russian Federation on December 21, 2023 at 08:48 UTC. The launch window ran from 08:00 to 10:00 UTC. It was Russian Space Forces's 138th launch, 6th this year and humanity's 6,578th orbital launch attempt. It was the 18th Soyuz 2.1b flight and the 3rd this year. The payload was bound for Sun-Synchronous Orbit (SSO). Kosmos-2573, one of 2 catalogued objects, reached a 345 × 506 km orbit inclined 97.6°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
Note: Payload identity uncertain, possibly Bars-M #5 or a similar satellite as the insertion orbit is similar. Bars-M is the second incarnation of the Bars project, which was started in the mid 1990ies to develop a successor for the Komtea class of area surveillance satellites. The original Bars project was halted in the early 2000s. In 2007, TsSKB-Progress was contracted for Bars-M, for which reportedly the Yantar-based service module was replaced by a new developed advanced service module. The Bars-M satellites feature an electro-optical camera system called Karat, which is developed and built by the Leningrad Optical Mechanical Association (LOMO), and a dual laser altimeter instrument to deliver topographic imagery, stereo images, altimeter data and high-resolution images with a ground resolution around 1 meter.
