Live coverage: Ariane 5 blasts off with two Intelsat satellites

Launch teams are readying three rockets for a series of blastoffs this week from Cape Canaveral to loft a classified orbiting spy platform for the U.S. government, a long-delayed Argentine radar imaging payload, and the next set of Starlink broadband satellites.

After replacing a faulty inertial measurement system blamed for a scrubbed launch attempt Sunday, a Soyuz rocket headed to space from French Guiana today with five satellites, including the next spacecraft for Europe’s multibillion-dollar Earth observing network and a French experiment to probe the validity of Einstein’s theory of general relativity.

The U.S. Air Force fired a new rail-launched rocket into space from Hawaii at 10:45 p.m. EST Tuesday (0345 GMT Wednesday), but the Super Strypi vehicle failed about a minute after liftoff with 13 satellites on-board.
