James Webb Space Telescope reaches final destination around L2

on 25 January 2022

On 24 January 2022 the NASA/ESA/CSA James Webb Space Telescope was successfully inserted in a halo orbit around L2, its final home, 1,5 million km away from Earth. The final mid-course burn lasted for nearly five minutes and added only about 1.6 metres per second to Webb’s speed.

The orbit around L2 Webb has several advantages. It is keeping the Sun, Earth and Moon in the same direction, allowing the sunshield to protect Webb at all times. Webb is also avoiding entering the shadow of the Earth or Moon. Finally this position makes communication with the Earth easier.
