Live coverage: Ariane 5 lifts off on its first Galileo launch

European engineers who developed a small satellite hitching a ride to the International Space Station aboard a SpaceX supply ship Monday are gearing up for a first-of-a-kind experiment to examine ways to snare a chunk of space junk and tug it back to Earth.

Rolling out for its first liftoff of the year, an Ariane 5 rocket journeyed out of a launcher assembly building Thursday and rode railroad tracks to its launch pad in French Guiana with two European communications satellites.

NASA and SpaceX have delayed the launch of the Crew Dragon “Resilience” spacecraft from the Kennedy Space Center until 7:27 p.m. EST Sunday (0027 GMT Monday) to wait for improved downrange weather and sea conditions, and better onshore winds at the launch site.
