Live coverage: Ariane 5 blasts off with two Intelsat satellites

Four satellites fastened to the top of an Ariane 5 rocket will grow Europe’s space-based Galileo navigation network Thursday morning with a launch from the South American jungle.

Two spacewalkers attached a new docking port to the International Space Station Friday, clearing the way for U.S. crew ferry ships being built by Boeing and SpaceX to begin test flights to the lab complex next year.

United Launch Alliance kicked off its 2018 launch campaign with a Delta 4 rocket flight at 2:11 p.m. PST (5:11 p.m. EST; 2211 GMT) Friday from Vandenberg Air Force Base in California. Gusty winds forced officials to call off a launch attempt Wednesday, and technical problems halted a countdown Thursday multiple times. The Delta 4 launched with a top secret spy satellite for the National Reconnaissance Office.
