Ariane 5 to send a duo of communications satellites into orbit

Arianespace is all set to conduct its eighth mission of the year, which will send two communications satellites into space atop the company’s workhorse Ariane 5 booster. Liftoff will take place from the Ariane Launch Complex № 3 (ELA-3) in Kourou, French Guiana. The 45-minute launch window starts at 5:30 p.m. local time (4:30 p.m. EDT; 20:30 GMT) on Tuesday, Oct. 4. The mission, designated VA231, will deliver GSAT-18 and Sky Muster II (also known as NBN-Co 1B) commsats into a geostationary orbit. The flight will last one hour and 22 minutes, with the Sky Munster II being released at 28-and-a-half minutes after launch and GSAT-18 being deployed some four minutes later. More
