KOUROU, French Guiana (ESA PR) — The James Webb Space Telescope has arrived safely at Pariacabo harbour in French Guiana. ESA in close collaboration with NASA will now prepare this once in a generation mission for its launch on Ariane 5 from Europe’s Spaceport this December.

Few space science missions have been as eagerly anticipated as the James Webb Space Telescope (Webb). As the next great space science observatory following Hubble, Webb is designed to resolve unanswered questions about the Universe and see farther into our origins: from the formation of stars and planets to the birth of the first galaxies in the early Universe.
