Cataloged as 40667, 40668 in 177 x 285 km x 81.4 deg orbit, which is very close to the parameters of the previous such mission

I know they don't stay up long but in such a low orbit they must do a lot of station keeping to maintain that.

Perigee will be raised by 20 km or so to ease orbital decay issues, but expect around a dozen orbital maintenance manoeuvres while the satellite is in orbit for 120-130 days.

Thanks for that info.

Just for information, I am attaching (if the technology works!) a listing of the Cosmos 2495 orbital manoeuvres from last year: this is from a paper that i am currently working on that is reviewing the final two launches in the Kobalt-M series.

Cosmos 2505 has performed its first orbit-raising manoeuvre, from 175-275 km to 193-275 km (Jun 8.56).

Kosmos-2505 (Kobal't-M) appears to have landed; JSPOC decay notice for Sep 18.
I calculate a likely descent with deorbit around 0840 UTC and landing around 0909 UTC; I imagine Phil Clark will
have his own estimate. Phil?
Orbital life was 104.7 days

Highly appropriate that the final film-return satellite should come down and thus the series is retired at the time that I was retiring from full-time work!
However, a quick look at the numbers suggests to me a descent on September 17 at about 22:19 UT: then again right now it is a bit early for me after last night's celebrating.
A pity that this satellite wasn't a record-breaker in terms of duration. I can now finish my JBIS paper about the Russian photoreconnaissance programme and get that sent in in the the next two weeks.

Nice to get that observational confirmation.
Now if only there were reports of the small SpK film capsules being recovered at some point in the past couple months... has any info come out on their recovery dates?

There is enough spare hardware left to build another one and launch next year but there are not any plans to do so. Instead looks like may end being reused for parts or given for display.

A pity that it wasn't put together for the London Science Museum!

Kobalt-M n.º 565 is schedule for launch on May 15, 2015, from the Plesetsk Cosmodrome using 14A14-1A Soyuz-2-1A (78072171).
According to Anik the fairing had serial №78072158. That suggests that the rocket used for this launch, was not the original. No other type of satellite used this type of fairing, article 14С736.
So is there a rocket with serial №78072158? After the previous failed launch of Progress M-27M, was the rocket substituted with №78072171?
There are two types of serial numbers; ones that start with a 7, and those that contain 15000. Rockets prepared for the military have the serial numbers starting with a 7.
Rocket with №78072171 painted on the side, would have been referred to in the factory as 20М136С, the 20th machine of the 136th series, or just 20/136 (once again according to Anik). Mostly the serial numbers starting with a 7, correlate with the factory number. So if №78072171 is 20/136, I would expect №78072158 to be 7/136.
http://novosti-kosmonavtiki.ru/forum/messages/forum13/topic304/message1399968/#message1399968There is a Soyuz-2-1a rocket with factory number 7/136. It is to be used to launch Kanopus-V-IK, though it is being supplied to fulfil the requirement under contract №353-1193/12 dated 11th September 2012, for the launch of Rezonans.
http://forum.nasaspaceflight.com/index.php?topic=37032.msg1440451#msg1440451So rocket №78072158 has become rocket №Т15000-018? That leaves the question of what rocket was originally being prepared to fulfil the Rezonans contract; and what payload was №78072171 assigned to carry?
