20231227 Cosmos-2574.png On 27 December 2023, at 10:03:44 MSK (07:03:44 UTC) crews of the Air and Space Forces conducted a successful launch of a Souyz-2.1v launcher from the 43/4 launch pad of the Plesetsk test site.

The satellite delivered into orbit was designated Cosmos-2574. It received international designation 2023-209A and registered by NORAD as object 58658.

Cosmos-2574 was deployed on a circular orbit with altitude of about 330 km, which suggests that it is similar to the small imaging satellites of the EO MKA/Razbeg type. It is believed to be a Razbeg #1/MKA-V satellite. Previous launch of a satellite of the MKA-class satellites took place in March 2023.

Object 2023-209C/59022, believed to be debris, separated from Cosmos-2574 on 23 February 2024. it re-entered atmosphere around 5 March 2024. This separation took place about two days after Cosmos-2574 approached Cosmos-2575, which happened around 1500 UTC on 21 February 2024.

Later, the two satellites were positioned in close proximity again. One approach, with the separation distance of about 10 km, took place on 12 March 2024.
