Live coverage: Two satellites lift off aboard Ariane 5

Veteran Soyuz commander Yuri Malenchenko, outgoing space station skipper Tim Kopra and British astronaut Tim Peake departed the International Space Station early Saturday aboard the Soyuz TMA-19M capsule and landed in Kazakhstan at 0915 GMT (5:15 a.m. EDT).

An Ariane 5 rocket ignited its hydrogen-fueled Vulcain 2 main engine and two solid rocket boosters to send two Intelsat communications satellite into orbit this week, casting a brilliant glow across its launch base carved from the jungle of French Guiana.

Europe’s next-generation launcher family has moved a step closer to reality with the signature of nearly $3.8 billion in contracts for development of the Ariane 6 rocket and an upgraded version of the lightweight Vega booster.
