Photos: Ariane 5 rolled out to jungle launch pad

Launch managers in French Guiana have delayed liftoff of a European gravitational probe pathfinder at least one day to study out-of-bounds thermal readings from the upper stage of its Vega rocket booster, officials said Tuesday.

Take a trip around the perimeter of the Ariane 5 rocket’s launch zone in Kourou, French Guiana, where two Intelsat communications satellites are poised for liftoff Wednesday.

An unexpected reading from a ground sensor prompted SpaceX to scrub the planned launch of a Falcon 9 rocket Thursday with 60 more Starlink broadband satellites. It was the second last-minute abort of a rocket launch on Florida’s Space Coast in less than 10 hours, following a hold Wednesday night just before engines ignited on a United Launch Alliance Delta 4-Heavy rocket.
