Launch report
So we again welcome the Silver Hypergolic Monster(TM) to the steppes of Kazakhstan - flying for the third time in 8 weeks. Nothing special there....
What's on top of it, however, is another story. Briefly speaking, this satellite shouldn't have existed at all. For Eutelsat 3D used to be Eutelsat W3D, sistercraft of W3C and was ordered in 2010
after the loss of another sistercraft W3B shortly after launch on an Ariane 5 rocket in October 2010 due to a huge propellant leak.
Ironically W3C didn't suffered from such a problem when being launched by the Chinese a year later - something that satellite controllers would like to see again tomorrow.
This is the 3rd commercial mission of the year for ILS and the 80th ILS Proton mission since the first commercial flight of the Proton in April 1996.
This is the 7th Eutelsat satellite launched with Proton and the 9th Thales Alenia Space-built satellite launched on Proton.

Mission Summary
EUTELSAT 3D has been built for Eutelsat by Thales Alenia Space using its established Spacebus 4000 platform.
With a baseline design equipping it to strengthen Eutelsat’s overall in-orbit flexibility and back-up from multiple orbital slots, EUTELSAT 3D will initially be located at the 3° East orbital position to address high-growth video, data, telecom and broadband markets.
Through its configuration of Ku and Ka transponders connected to three footprints, the new satellite will serve customers in Europe, North Africa, the Middle East and Central Asia. A fourth service area in the Ku-band will address markets in sub-Saharan Africa.
EUTELSAT 3D will operate at 3° East until the deployment of the EUTELSAT 3B satellite to this position in 2014 to provide spectrum growth and high levels of operational flexibility in C, Ku and Ka bands. It will subsequently continue service at 7° East.

Eutelsat 3D Ascent Profile
The Proton-M first three stages place the orbital unit (OU), which consists of a Breeze-M upper stage, adapter system and Eutelsat 3D, into a 51.5° inclination suborbital trajectory.
Proton-M powered flight lasts 582 seconds. The OU powered flight begins at the moment of the third stage separation.
Immediately after the separation of the third stage booster, the Breeze-M stability engines start, damping the angular velocities of the third stage separation and then providing orbital unit orientation and stability during coast flight along a suborbital trajectory to await the first burn. The upper stage follows a five-burn injection profile.
