Webb flies Ariane animation

Artist's animation of the James Webb Space Telescope (Webb), folded in the Ariane 5 rocket during launch from Europe's Spaceport in French Guiana.

Webb is the next great space science observatory, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. Webb will see farther into our origins – from the formation of stars and planets, to the birth of the first galaxies in the early Universe.

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.

Webb is an international partnership between NASA, ESA and CSA.
