[REPLAY] Webb launch success - VA 256
25 December, Ariane 5, operated by Arianespace, accomplished a flawless launch on its 112th flight from the Guiana Space Centre to orbit NASA’s James Webb Space Telescope.
Ariane 5 inserted Webb into a trajectory that will take it directly to its ultimate orbital destination at the L2 Lagrange point 1.5 million kilometres from Earth, which it will reach in 29 days. Fully deployed on arrival at L2, Webb will then switch on and test all its four instruments before being fully operational around June 2022.
