Ariane 5 rocket returning to hangar for sensor swap

August 1, 2020

Arianespace is returning an Ariane 5 rocket — loaded with three U.S.-built satellites — back to its final assembly building in French Guiana to replace a suspect sensor on the vehicle that prompted officials to cancel a launch attempt Friday. Arianespace said Monday that the swap will delay the launch until around Aug. 14.

Arianespace’s third Ariane 5 launch of the year was set liftoff Friday from Kourou, French Guiana, but an issue with a sensor on the rocket’s first stage liquid hydrogen tank caused officials to scrub the launch attempt. The Ariane 5 is poised to carry three U.S.-built commercial satellites into orbit, while testing a few rocket upgrades, including a modified fairing needed for the launch of the James Webb Space Telescope next year.
