Launch readiness review clears Ariane 5 for its August 6 liftoff with Intelsat 39 and EDRS-C

Arianespace’s third Ariane 5 flight of 2019 has been given the “green light” for liftoff next week following today’s launch readiness review, which was conducted at the Spaceport in French Guiana.

This milestone confirmed that the launch vehicle and its dual-satellite payload – comprised of Intelsat 39, for global operator Intelsat; and EDRS-C, based on a public-private partnership between Airbus and the European Space Agency – are flight-ready, along with the Spaceport’s infrastructure and the network of downrange tracking stations.

The next steps for Ariane 5

With approval granted, Ariane 5 is cleared for Monday’s rollout from its Final Assembly Building to the ELA-3 launch zone. Liftoff will occur on August 6, during a 2-hr., 21-min. launch window that opens at 4:30 p.m. local time in French Guiana.

Ariane 5 will deliver a total payload lift performance of approximately 10,661 kg. on the mission to geostationary transfer orbit (GTO), which is designated Flight VA249. This total includes the two satellite passengers, plus the workhorse vehicle’s dual-payload deployment system and integration hardware.
