NASA James Webb Space Telescope Program Scientist Eric Smith left, NASA James Webb Space Telescope Program Manager Jeanne Davis, NASA Program Director for the James Webb Space Telescope Greg Robinson, and Arianespace’s Vice President for French Guiana Bruno Gérard, right, talk as they wait for Arianespace's Ariane 5 rocket with NASA’s James Webb Space Telescope onboard, to rollout to the launch pad, Thursday, Dec. 23, 2021, at Europe’s Spaceport, the Guiana Space Center in Kourou, French Guiana. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Photo Credit: (NASA/Bill Ingalls)
