Live coverage: Ariane 5 blasts off with two Intelsat satellites

Two ion-driven communications satellites launched from Cape Canaveral on March 1 have begun novel maneuvers using electric propulsion to reach operating posts 22,300 miles over the equator.

Astronauts Butch Wilmore and Terry Virts suited up and ventured outside the International Space Station on Sunday on their third spacewalk in eight days to install equipment to help future commercial crew capsules built by Boeing and SpaceX navigate to the complex.

An upgraded model of SpaceX’s Falcon 9 rocket fired into orbit early Sunday from Florida’s Space Coast, hoisting a record-setting 7.8-ton communications satellite for Telesat toward its planned perch more than 22,000 miles over the equator.
