Live coverage: Two satellites lift off aboard Ariane 5

Two communications payloads — one for Intelsat and another for Europe’s data relay satellite system — lifted off from French Guiana aboard an Ariane 5 rocket at 1930 GMT (3:30 p.m. EDT) Tuesday.

The French military’s newest sharp-eyed optical surveillance satellite lifted off at 1637 GMT (11:37 a.m. EST) Wednesday from French Guiana aboard a Russian-built Soyuz launcher, marking Arianespace’s 11th and final launch of 2018. The Soyuz rocket and Fregat upper stage will place the CSO 1 spacecraft into orbit around 500 miles (800 kilometers) above Earth. Managers delayed the launch from Tuesday due to unfavorable high-altitude winds.

European Space Agency Director General Josef Aschbacher said Thursday the Ariane 6 is expected to launch for the first time between June 15 and July 31, 2024. The determination comes on the heels of what ESA determined to be a successful hot fire test of the rocket’s main engine.
