Following a 24-hour postponement due to winds at altitude over the ELA-3 launch complex, Ariane 5’s heavy-lift flight with Hispasat 1E and KOREASAT 6 is on track for a liftoff this evening from Europe’s Spaceport. The final countdown is now underway, with today’s liftoff planned during a launch window that opens at 6:27 p.m., local time in French Guiana.
