The James Webb Space Telescope, configured for flight, was moved from the cleanroom to the payload preparation facility for fuelling at Europe’s Spaceport in French Guiana on 11–12 November 2021.
Webb will be loaded with propellants before being mounted on top of the rocket and then encapsulated by the Ariane 5 fairing.
Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace.
Webb is an international partnership between NASA, ESA and the Canadian Space Agency (CSA).
