Mission Profile: 
The Proton M launch vehicle, utilizing a five-burn Breeze M mission design, will lift off from Pad 39 at the Baikonur Cosmodrome. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage and the Ciel II satellite into a suborbital trajectory. From there the Breeze M will place itself and the spacecraft into a circular parking orbit. Following four additional burns of the Breeze M, the satellite will be injected into a geostationary transfer orbit. Separation will occur at approximately L+9 hours, 12 minutes.
