What a beautiful snow launch! Thanks for the coverage everyone

NORAD has already found 2013-077A/39487 in the standard 5000 km apogee intermediate orbit (263 x 4993 km x 50.57 deg.) about 2 hours ago.

As per http://novosti-kosmonavtiki.ru/forum/messages/forum12/topic13089/message1179025/#message1179025, this mission utilized a four burn Briz-M mission design.

So, similar to AM-33 except for inclination. We should next see the DTB drop tank in a 400 x 35500 km x 47? deg orbit
following MECO-3 which should have happened around 1437 UTC (so 2 hours ago). That will leave just the
apogee burn which should come sometime in the 1930-2010 UTC range, presumably at the end of that range given
the quoted Briz/payload separation time.

"The satellite separated from the Briz-M upper stage and went into geostationary orbit"
so, does it mean that it was a direct injection into GEO?...let's wait for next TLE

Final orbital position will be 140°E

Still waiting for the next TLE! But yes, my guess is direct to GEO on the last burn.

" Express-AM5 will continue to move to the target orbit with the help of electro-propulsion. This scheme is for the first time used in the Russian space industry. Final ascent of the spacecraft to the target orbit will last about 90 days. "

This is an interesting development. For the future Yenisey-A1, based around the same Ekspress-2000 platform, in the documentation it references communication via the Luch-5 satellite network whilst climbing to orbit under electric propulsion.
It also raises the question about Yamal-401 which is another Ekspress-2000 based satellite; will it also do the same or is it to fly on a phase IV Proton-M Briz-M?

And as of Dec 31, still no more TLEs from any of the objects of this launch after the 262 x 4992 km MECO-2 orbit.

Surprising that at least the DTB drop tank has not been located in GTO; the amateurs have found something that
might be the payload in near-GEO, JSPOC needs to get its act together...

Space Fence shutdown?

Perhaps for the DTB, yes. Space Fence wouldn't have found the two objects in GEO though - this speaks to wider deficiencies in the current US space surveillance posture.

13 days after launch, we still have no TLE for the spacecraft.

Object A (presumably Briz-M's DTB/APT) was yesterday in 394 x 37706 km x 49.43° orbit

input~2 · « **Reply #59 on:** 01/11/2014 08:30 pm »

Finally the spacecraft was tracked yesterday.
From TLEs published to-day:
Old Object A (the DTB/APT) is now object C (2013-077C/39489)
New Object A is the spacecraft:
2013-077A/ 39487 in 33772 x 37618 km x 0.163° (epoch Jan 10, 1745UTC)
New Object B is Briz-M:
2013-077B/ 39488 in 36825 x 41343 km x 0.694° (epoch Jan 10, 1640UTC)

Thanks JSPOC!
