Live coverage: Two satellites lift off aboard Ariane 5

Liftoff of an Ariane 5 rocket from a tropical launch pad in South America was halted moments after its main engine ignited Tuesday in a rare last-second abort for the heavy-lift launcher.

SpaceX launched its first mission of the year Monday at 9:19 p.m. EST (0219 GMT Tuesday), when a Falcon 9 rocket lifted off from Cape Canaveral with SpaceX’s third batch of 60 Starlink broadband satellites.

Two U.S.-built commercial communications satellites moved to their last stop on Earth on Tuesday, when an Ariane 5 rocket rolled out to a launch pad at the edge of the Amazon jungle on the eve of liftoff.
