From the previous video we can see that the long serial number of this launcher is 6304287975.

Hi, everyone. I've got a few new questions about the launch.

1. In the mission document provided by federal space agency in http://www.mcc.rsa.ru/luch_5v.htm, there is a parameter concerning Luch-5V, which is Количество антенн модуля целевой аппаратуры (МЦА) : 9. Could anyone familiar with Russian provide an explanation of this?

2. In the ensuing launch timeline of the webpage, the auxiliary propellent tank of Briz-M is jettisoned after the 2nd burn with 3 burns left. I remember that in a typical 5-burn mission, the APT is jettisoned after the 3rd burn with ~10 min burn time left, like the Turksat-4A mission. So does anyone have an idea of the underlying reason for this?

3. Sorry to bring up the question again. Is this launch using Phase IV or Phase III Proton-M/Briz-M, as the current information seems confusing. Could anyone provide some information sources.

Thanks very much and looking forward to the answer :-)

Quantity of antennas of satellite payload.

It is mistake - DTB separation will be after Briz-M third burn.

It is mistake - DTB separation will be at 08:23:01 UTC after Briz-M third burn.

Many thanks, anik!

Anik will Luch now operate to give the ISS communication without many the dark areas we now have?

So this is the first ever launch of Proton-M phase IV version right?


3. Sorry to bring up the question again. Is this launch using Phase IV or Phase III Proton-M/Briz-M, as the current information seems confusing. Could anyone provide some information sources.


So nobody knows?  :-\

Many dark areas?  TDRS covers 100% of the ISS orbit (with TDRS-Z) but there are LOS periods--apparently due to conflicts with other users, station structure blockages, etc.  The dark areas Luch will fill are from Russian ground stations--once the hardware to broadcast to the satellites is launched and installed later this year according to info elsewhere on this site.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."
