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] References1. ^{{cite web|url=http://space.skyrocket.de/doc_sdat/persona.htm|title=Persona (14F137)|first=Gunter|last=Krebs|work=Gunter's Space Page|accessdate=29 June 2013}} {{Orbital launches in 2008}}2. ^1 2 3 {{cite web|url=http://www.planet4589.org/space/jsr/back/news.598|title= Issue 598|accessdate= 29 June 2013|first=Jonathan|last=McDowell|date=12 August 2008|work= Jonathan's Space Report}} 3. ^{{cite web|url=http://russianforces.org/blog/2008/07/launch_of_cosmos-2441_-_first.shtml|title=Launch of Cosmos-2441 - first Persona optical reconnaissance satellite|first=Pavel|last=Podvig|publisher=RussianForces.org|date=26 July 2008}} 4. ^{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|first=Jonathan|last=McDowell|work=Jonathan's Space Page|accessdate=29 June 2013}} 5. ^{{cite web|url=http://planet4589.org/space/log/satcat.txt|title=Satellite Catalog|first=Jonathan|last=McDowell|work=Jonathan's Space Page|accessdate=29 June 2013}} 6. ^1 {{Cite web|url=http://www.russianspaceweb.com/persona.html|title=Persona (14F137) spy satellite|first=Anatoly|last=Zak|work=RussianSpaceWeb|accessdate=29 June 2013}} 7. ^{{cite web|url=http://russianforces.org/blog/2009/02/persona_satellite_failure.shtml|title=Persona satellite failure|first=Pavel|last=Podvig|publisher=RussianForces.org|date=13 February 2009|accessdate=29 June 2013}} 8. ^{{cite web|url=http://russianforces.org/blog/2013/06/launch_of_cosmos-2486_-_person.shtml|title=Launch of Cosmos-2486 - Persona optical reconnaissance satellite|date=7 June 2013|first=Pavel|last=Podvig|publisher=RussianForces.org|accessdate=29 June 2013}} 3 : Spacecraft launched in 2008|Reconnaissance satellites of Russia|Spacecraft launched by Soyuz-2 rockets |
