Now cataloged:

 
 39159 21A   Proba-V                787 x 828 km x 98.7 deg
 39160 21B  VNRedSat-1A          669 x 673 km x 98.1 deg
 39161 21C   ESTCube-1            658 x 670 km x 98.1 deg
 39162 21D   VESPA Upper Part   670 x 815 km x 98.7 deg 
 
 

Only one TLE set so far for Proba (vs 3 for VNREDSAT) so they may not have
locked up on it yet, we'll see when they get a second elset.

And the failure to catalog the AVUM stage presumably means it was successfully deorbited, which was the last part of mission success I was waiting to hear about
(they made a big deal about how space debris reduction was important to them,
so shouldn't they cover the deorbit burn on an even level with the deployments? Nerdy grumble...)

Congratulations ESA and Arianespace!

I second your nerdy grumble as I prefer to follow along until there is no more telemetry to follow.  But the main thing is it worked and my hearty congratulations to all involved.

A shame that VESPA has to add to the debris problem, at least for a few years until, presumably, it decays.  Perhaps some wrench jockey out there can figure out a way to insert multiple satellites without needing to jettison dispenser parts.

Of course VV-02 only carried a fraction of its payload rating.  I doubt that it will be possible to outright deorbit AVUM on every mission.

Congratulations to all the Vega team!
I've noticed that the solution to the telemetry blockage by the exhaust plume was solved by building a new telemetry station. Would this also be used by Ariane 6?

New TLE set for Proba-V shows it in 811 x 820 km, closer to the planned circular orbit. I don't think the sat has propulsion, so the original TLE was just inaccurate.

Per SFN the AVUM succesfully performed it's fifth burn to deorbit the AVUM stage: http://www.spaceflightnow.com/vega/vv02/status.html

figured I'd add this here:

Canadian firm smartens up new Earth-observing satellite
CBC News Posted: May 8, 2013 1:24 PM ET

A European mini-satellite launched this week will be able to keep a steady eye on Earth's vegetation as it hurtles through orbit, thanks to smart software developed in Canada.

Sherbrooke, Que.-based NGC Aerospace designed the software that makes the PROBA-V satellite capable of automatically maneouvering to maintain the right position and orientation as it takes images of the Earth.

Looking back at Vega’s second flight

17 May 2013
 
http://www.esa.int/Our_Activities/Launchers/Looking_back_at_Vega_s_second_flight

Quote
Since Vega’s flawless second launch on 7 May from Europe’s Spaceport in Kourou, French Guiana, checks of the flight’s telemetry show the vehicle performed impeccably.

Quote
The upper stage’s fifth and last burn placed it on a path that ensured safe reentry within an hour, in compliance with new debris mitigation regulations.
 
Initial analysis shows that Vega’s mission was a complete success. A detailed analysis before the summer will verify the behaviour of all the vehicle’s subsystems.
 
Vega’s unrivalled success in its first two flights is an encouraging start in this light-lift launcher’s transition towards commercial operations.

ESTCube-1 is on a possible collision course with a space debris. The particle COSMOS 2251 DEB originates from the space junk cloud from the Irridium – Strela 2M collision in 2009. The closest contact is expected tomorrow, on Friday, August 2 at 04.40 UTC over the coastline of Antarctica. According to the United States Joint Space Operations Center, it will most likely be a near miss at about 200 meters. But we all remember the case of Ecuadorian Pegaso nanosatellite, which was destroyed by a space junk on May 23. Let’s all hope we will hear the signals from ESTCube-1 tomorrow at 07:07 UTC, when the first contact after the incident could be established from Estonia. If you choose to “like” this post, you express your support to our brave satellite in orbit, facing the possibility of being struck with energy similar to a simultaneous hit of 14000 rifle bullets.

7 new debris objects cataloged from the Vega VV02 launch in a 23:50 LTDN sun-sync orbit, consistent with a breakup of the VESPA adapter upper section, object 39162. Possibly the result of an impact by a small object?

The launch at Celestrak. You can see from the NORAD numbers, that the objects E-L are new.
