Ariane V has completed its 81st launch, the 77th to be fully successful. (The vehicle has a remarkably clean record, with no faults since the fourteenth launch, back in 2002.) This placed two commsats onto geosynchronous transfer orbit.
And if you want to know a bit more about the mission and how it works, check out this episode of KNews — where “K” stands for “Kerbal”. It includes a Kerbal Space Program simulation of an Ariane V flight profile. 😉
