Live coverage: Two satellites lift off aboard Ariane 5

The launch of a Japanese H-2A rocket with the Emirates Mars Mission, a Mars orbiter developed in partnership between Emirati and U.S. scientists, was delayed Tuesday due to poor weather at the H-2A’s launch site on Tanegashima Island in southern Japan. Officials later announced that liftoff would not occur Thursday, again citing bad weather at the launch site. A new launch attempt is scheduled for Sunday, weather permitting.

Two U.S.-built Intelsat communications satellites have hitched on to an Ariane 5 rocket for launch from French Guiana next week, the first time the storied company has put two of its spacecraft on the same booster.
