Kosmos 2441 (Russian : Космос 2441 meaning Cosmos 2441), also known as Persona No.1, was a Russian optical reconnaissance satellite launched in 2008. The first Persona satellite, it failed a few months into its mission, which was scheduled to have lasted three to five years. It was the first Russian reconnaissance satellite to be placed into a Sun-synchronous orbit. [3]

Kosmos 2441 was launched by a Soyuz-2-1b carrier rocket flying from Site 43/4 of the Plesetsk Cosmodrome. The launch took place at 18:31:36 UTC on 26 July 2008, [4] and marked the first Soyuz-2-1b launch from Plesetsk. Following its successful deployment the satellite was given its Kosmos designation, and was assigned the International Designator 2008-037A and Satellite Catalog Number 33272. [5]

In February 2009, it was reported that Kosmos 2441 had failed shortly after launch. [6] The date of the failure was not announced, however the satellite was last seen to manoeuvre in September 2008. [7] The cause of the failure was reported to be an electrical problem, possibly caused by higher radiation levels encountered by the satellite in sun-synchronous orbit compared to previous satellites in lower-inclination orbits. [6] The next Persona satellite was not launched until 2013, when it was placed into orbit as Kosmos 2486. [8]

Persona is a class of Russian reconnaissance satellites, derived from the Resurs DK class of remote sensing satellite, in turn derived from the Soviet Yantar reconnaissance satellites. The satellites are built by TsSKB-Progress, and the optics by LOMO and the Vavilov State Optical Institute.

Meridian 2, also known as Meridian No.12L, was a Russian communications satellite. It was the second satellite of the Meridian system, which replaced the older Molniya series. It followed on from Meridian 1, which was launched in December 2006.

EKSKupol is a developing programme of Russian early warning satellites as a replacement for the US-KMO and US-K satellites of the Oko programme. The satellites are designed to identify any possible future ballistic missile launches, from outer space, and complement early warning radars such as the Voronezh. This gives advance notice of a nuclear attack and would provide information to the A-135 missile defence system which protects Moscow, as well as other Russian missile defense and counterattack resources. Six satellites are planned to be initially orbited. The first of these was launched on 17 November 2015 and as of November 2022, all six of them are in service.
