Mission details:

• SES-3, for SES World Skies (Princeton, NJ) and SES Engineering (Luxembourg), is an Orbital Star-2.4E with a fuelled mass of 3112 kg, using a Japanese IHI BT-4 apogee thruster. It carries a C/Ku band communications payload.
• The Briz-M was placed in an initial -477 x 189 km x 48.0 deg trajectory at 2325 UTC; it reached 133 x 273 km x 48.0 deg at 2333 UTC, 240 x 5000 km x 46.8 deg at 0039 UTC on Jul 16, jettisoned the DTB tank at 0259 UTC in a 341 x 215235 km orbit, reached 401 x 35252 km x 45.6 deg at 0303 UTC, and coasted to apogee. A further burn completed at 0704 UTC left SES-3 in a 3655 x 35757 km x 24.7 deg orbit; it separated from the stack at 0717 UTC. The Briz-M coasted for almost an hour and then jettisoned the payload adapter that separated SES-3 from Kazsat at 0812 UTC.
