BAIKONUR, Kazakhstan — International Launch Services completed its third and final 2017 commercial Proton mission today, launching the AsiaSat-9 telecommunications satellite from the Baikonur Cosmodrome.

Proton lifted off at 12:52 a.m. local time, performing first, second and third stage burns as planned, followed by five firings of the Breeze-M upper stage. The total mission lasted nine hours and 13 minutes.

ILS began launches this year in June after a year-long hiatus, half of which was spent investigating the cause of a premature second-stage engine shut down during the Intelsat-31 mission in 2016 (for which the launcher's Breeze-M upper stage compensated to complete the mission without incident), and the other half spent replacing second- and third-stage engines made with an incorrect solder material by manufacturer Khrunichev. Though the delays pushed out mission schedules, ILS has hailed the processes as evidence of Russia's reaffirmed commitment to quality assurance.

While ILS's year is complete, Russia's Proton rocket has one additional federal mission planned for December. Proton has launched four times this year — three commercial and one government.
