Live coverage: Ariane 5 rocket deploys satellites for Australia, India

Redesigned titanium steering fins will fly aboard a Falcon 9 rocket launching Sunday from California, part of upgrades SpaceX says will ease the reuse of future boosters.

After a four-day delay due to a ground power supply anomaly and unfavorable weather, an Ariane 5 rocket lifted off at 4:23 p.m. EST (2123 GMT) Tuesday to send into orbit a hush-hush communications satellite for the Egyptian military and a spacecraft to expand the capacity of Inmarsat’s mobile Internet service.

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.
