Live coverage: Atlas 5 countdown and launch journal

New video released by the Russian space agency Thursday shows the moment a Soyuz rocket ran into trouble around two minutes after liftoff with a two-man crew Oct. 11, when one of the vehicle’s four first stage boosters crashed into the Soyuz core stage.

A state-of-the-art satellite to provide high-speed Internet connectivity across North America, specializing in areas where terrestrial networks are not available, will be mounted atop its booster rocket Saturday in preparation for launch next weekend.

A package of communications and tech demo satellites for the U.S. Air Force rode a United Launch Alliance Atlas 5 rocket into an orbit more than 20,000 miles over the equator after liftoff from Cape Canaveral Saturday evening.
