The James Webb Space Telescope is safely stowed inside the fairing of ESA’s Ariane 5 launch vehicle, which is now on the launch pad undergoing final checks and fueling for a targeted liftoff at 12:20 GMT / 13:20 CET on December 25 from Europe’s Spaceport in Kourou, French Guiana.
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).
