Ariane 5 Mission VA238
Europe's Ariane 5 rocket is set to rumble off from South America on Wednesday to carry into orbit a pair of communications satellites for commercial operators Inmarsat and HellasSat as well as the Indian Space Research Organization. Inmarsat-S/HellasSat-3 and GSAT-17 are targeting liftoff from the Guiana Space Center during a 77-minute launch window opening at 20:59 UTC.
Ariane 5 will be in action for 42 minutes to lift the two satellites into an elliptical orbit peaking nearly 36,000 Kilometers in altitude to check off its fourth flight of the year.
