Highlights of the launch campaign for the James Webb Space Telescope, from its arrival at Europe’s Spaceport in Kourou, French Guiana, weeks of launch preparations, to launch on board an Ariane 5, and separation of the spacecraft and solar panel deployment.
Now in space and on its way to L2, Webb will undergo a complex unfolding sequence. In the months after, the instruments will be turned on and their capabilities tested. After half a year in space, Webb will start its routine science observations.
Webb will see farther into our origins: from the Universe's first galaxies, to the birth of stars and planets, to exoplanets with the potential for life, and our own Solar System.
