Live coverage: Ariane 5 blasts off with two Intelsat satellites

NASA is sure enough that Boeing and SpaceX can safely launch astronauts to the International Space Station by early 2019 to hold off paying Russia to keep flying U.S. crews to the research complex, and one official says a deadline to order parts for new Russian Soyuz crew capsules may have already passed.

The first Ariane 5 rocket scheduled for launch in 2018 has been topped off with two communications satellites for SES and Yahsat, moving the European booster closer to liftoff Thursday from a tropical launch pad in French Guiana with payloads to serve commercial and scientific missions.

A Soyuz rocket soared into orbit after firing off a launch pad in the Amazon jungle Friday, deploying two satellites nearly 15,000 miles above Earth to expand Europe’s Galileo system helping locate automobiles, airliners, and millions of other users around the world.
