Kosmos 2462 / Soyuz-U - 16 April 2010
« on: 04/16/2010 05:36 pm »
Kosmos 2462 was launched by a Soyuz-U from Plesetsk this afternoon. Can't quite tell from the translations whether the launch was at 15:00 or 15:02 GMT (19:00/19:02 Moscow time).

EDIT:
I have found an English source which gives 15:00 as the launch time.

The 15:02 time is when the rocket came under the control of the Titov mission control center (a bit like when control of Shuttle goes from KSC to Houston after it clears the tower).

Spacetrack now has it as 2010-014A in a 169 x 327 km x 67.1 deg orbit

Russian Cosmos Satellite Launched Successfully

17.04.2010

http://www.roscosmos.ru/main.php?id=2&nid=9117

Soyuz-U carrier blasted off this morning from Russian space port Plesetsk to loft a satellite of the Cosmos series. In orbit, the satellite was identified as Cosmos-2442.

The launch sequence and injection went nominal, official of the Space Forces informed.

According to Russian Space Forces Commander Oleg Ostapenko, Russia is planning to enlarge its constellation of military and dual-use spacecraft. This is the second spacecraft for the Ministry of Defense launched this year.
Liquid-propellant Soyuz U is used to launch satellites weighing up to 7200 kg to the orbits with altitude about  200 km. The first launch of the rocket occurred from Plesetsk on May 18, 1973. Since then, more than 430 Soyuzes have been launched.

According to my classification, it was the 1700th orbital launch attempt of a R-7 class vehicle.

What does mean launch attempt? Explain, please. You counted events on July 10, 1963; December 16, 1966; March 18, 1980; September 26, 1983. But there were not liftoff events, i.e. rockets were left on the launch pad. And where Soyuz rocket with Soyuz-12?

Whoooowwwwww tahnk you very much anik ! This is a very big mistake ! It is corrected now.

I count launches of 10 july 1963, 14 december 1966, 18 march 1980 and 26 september 1983 because they were launch attempts, even if the lift-off didn't occur.

I do NOT count the attempt of 10 january 1997, because the launcher was reused for another mission, so I consider it like a delay.

(when you do such a list, you have to make some choices...)

Yes, December 14, 1966, I am sorry for mistake.

Your criteria for launch attempt is not clear for me. For example, what to do with such event: rocket is transporting to launch pad, crash and rocket can not be used for launch in future. Is it launch attempt? Or, for example, another event: rocket is on the launch pad, meteorite bump and rocket can not be used for launch any more. Is it launch attempt? Where does your criteria for launch attempt begin? From fuelling?

I do not count launch attempts, because it is difficult. I count launches, where launch links to lift-off. So for me, it was 1697th R-7 launch with aim to insert satellite on orbit.

For me, a "launch attempt" is not linked with a lift-off, but with the presence of a rocket at the cosmodrome.

In the two examples you give (crash and meteorite), I would count that as "launch attempts", because a launch would be attempted, even if it does not occur actually.

I agree this may not be the best way to count, but as I've already said, we all have to make choices !  :)

I am sorry, it was actually 1696th launch, because I have accidentally forgotten to exclude Soyuz-2-1A launch in 2004, which was suborbital, not orbital.

Nicolas PILLET, you should point it too. :)

Also, the launch on June 12, 1975 was performed by Soyuz-U rocket, not Voskhod.

I've asked myself a lot of question about this launch, because at the time, Roskosmos said it was actually orbital, but that the payload was deorbited as soon as it reached orbit...

Thanks, I correct it. Call me Nicolas !  :D

Nicolas, I talked with many people about this launch. They said it was suborbital launch intentionally. There were technical problems during ascent, but they caused steeper suborbital trajectory.

Who is right?

According to http://www.plesetzk.ru/index.php?p=inf034&d=doc/inf, there were six Soyuz-U launches from Plesetsk cosmodrome in 1975.

It does not matter what he wrote, it is official information from archive of TsSKB-Progress enterprise and archive of Plesetsk cosmodrome.

What a pleasant discussion!

Now my question: is there a chance that the R-7 rocket familly to reach the 2000th launch (attemp?!) during its remaining exploitation life?

Considering the future existence of the light version (Soyouz 2.1v) and the "Kourou version" it seems that is not impossible...
