Soyuz-2.1b launch with Resurs-P1 - June 25, 2013

[Nicolas PILLET]

ON 5th april 2012, the satellite was transfered in the TsSKB-Progress's Control and Testing Station (KIS).

According to Novosti kosmonavtiki forum, the launch is planned on September 30th.

The launch is planned on November 30th.

According to http://www.samspace.ru/News/SUB_NEWS/09-10-12.htm the satellite has arrived to Baikonur cosmodrome.

[Satori]

At Baykonur specialists started to prepare the satellite for launch http://www.roscosmos.ru/main.php?id=2&nid=19586 (in Russian).

Surprisingly, according to this picture, Resurs-P has the same index as Yantar-4KS1 (11Ф694).

That is just on the frame to support it? Pictures of Resurs-DK show the same.

The Resurs-P payload has not been flown yet

Why is Soyuz 2-2.1b being used for a payload that is normally  flown on Soyuz-U?   

To my knowledge, Soyuz-U and Soyuz-FG launchers are now only being used for manned crew and cargo missions through 2015 as a part of analog Soyuz series phase-out to newish digital Soyuz-2 series.

Sun-synchronous orbit

Soyuz-U only had the power to deliver Resurs-DK to 70° orbit.

The И15000 indicates that this is a rocket released in 2010. This suggests that this is the rocket always intended for Resurs-P, factory number 31/134?

Let me dispense with all of this as best I can.

Resurs-P is derived from Resurs-DK, which is simply a modernization of older optical reconnaissance systems such as Yantar-4KS, which have been launched into 98 degree orbits by Soyuz-U (Cosmos 2441). 

Note that Resurs-DK1, launched by Soyuz-U to 70 degrees,  had sufficient additional payload mass to carry the 500 kg Italian Pamela experiment module. This satellite COULD have been injected to 98 degrees if the Pamela experiment were not also flown, so Soyuz-U has plenty of capability to put Resurs-DK spacecraft into 98 degrees.

So, why does Resurs-P1 require Soyuz-2?

Soyuz U and FG have finished flying all non-ISS flights planned for them so Soyuz-2 is the only available Soyuz option.

It does raise many questions but I have found one reference from 2011 which indicates the rocket could by Soyuz or Soyuz-2 from Baikonur, but that is odd considering Soyuz-2 rocket was already ordered. But seeing that the rocket’s factory machine-series number was already known maybe it was left over from another satellite?

Kosmos-2441 was a Persona launched by Soyuz-2 from Plesetsk.

The last Neman was launched into 191 km x 299 km 64,78° orbit and was only expected to last 200 days. Resurs-DK was originally to go 97° from Plesetsk using Soyuz-2 and expected to last 3 years; and also to carry a 200 kg additional payload (but that ended up being 470 kg and 9 kg).

Resurs-P is going to be in an 475 km circular orbit 97,276°.

Persona much heavier than Yantar-4KS, at the limit Soyuz-2.1b. Was the modernization of the control system.

Выявленное по результатам пусков РН  «Союз-2»  в 2006 г. существенное возрастание погрешностей действия уровнемеров СУРТ не сказалось на конечных результатах выведения КА – в силу располагаемого резерва в грузоподъёмности РН. Но следует иметь в виду, что:
