Live coverage: International crew lands in Kazakhstan

Clad in pressurized spacesuits, two Russian cosmonauts headed outside the International Space Station on Wednesday and hand-released four tiny CubeSats and installed hardware for a German experiment to track animal migration.

Making its third try after back-to-back aborts, a Falcon 9 rocket successfully launched the commercial Intelsat 35e communications satellite Wednesday from NASA’s Kennedy Space Center in Florida. Liftoff from launch pad 39A occurred at 7:38 p.m. EDT (2338 GMT).

An electrical problem on SpaceX’s drone ship parked just off the coast of Cape Canaveral prompted SpaceX to scrub a Falcon 9 launch attempt early Friday, delaying the start of a resupply mission to the International Space Station by 24 hours.
