The James Webb telescope has completed testing and is ready to be sent to the launch site.
On August 26, NASA announced that the telescope had passed all the tests and is now being prepared for transport by water to the Kuru Cosmodrome, which is located on the northeastern coast of South America. Shipping may start in September.
After the “James Webb” is delivered to the spaceport, experts will make sure that it is not damaged, refuel and remove all protective covers from a number of elements of the telescope. It will then be placed under the nose cone of the Ariane 5 launch vehicle.
The launch of the telescope is scheduled for mid-November, but it could drag on until early December 2021.
If the launch is successful, the observatory will deploy solar panels, a sunscreen and a main mirror. And then in a month it will reach the halo orbit around the second Lagrange point in the Sun – Earth system, where it will work for 5–10 years.
