Live coverage: Two satellites lift off aboard Ariane 5

An Ariane 5 rocket topped by a heavyweight communications satellite for Eutelsat emerged from its hangar in French Guiana on Monday for a railroad ride to a nearby launch pad for final flight preps.

Three days after launching from Cape Canaveral, SpaceX’s Dragon cargo craft has arrived at the International Space Station with around 5,600 pounds of supplies and experiments. The automated, unpiloted supply ship was snared by the station’s robotic arm at 7:21 a.m. EST (1221 GMT) Saturday.

If you plan to watch athletes compete on the track or in the water during this year’s Summer Olympics in Rio de Janeiro, there’s a good chance the television signals will be relayed from Brazil using a new Eutelsat communications satellite launched Wednesday aboard an Ariane 5 rocket.
