SES-1 on launcher

Khrunichev/International Launch Services has launched the SES-1 satellite for SES World Skies. SES-1 is an Orbital Star-2.4 satellite replacing AMC-2 and AMC-4 with Ku and C band services over the US at 101 deg W. SES World Skies combines the old New Skies Satellites (based in the Hague) and Americom (based in Princeton). The Proton put the upper stage in a -483 x 195 km x 51.5 deg trajectory. While the Proton third stage fell back towards re-entry over the Pacific at around 1144 UTC, the Briz-M ignited to reach 191 x 195 km, 297 x 4999 km x 48, 496 x 33923 km x 46 and 33855 x 33881 km x 0 deg. The DTB additional propellant tank was tracked in a 518 x 33779 km x 46.2 deg orbit.
