This main milestone, carried out with Arianespace, the Webb launch service supplier, confirms that Ariane 5, the Webb spacecraft and the flight plan are set for launch. It additionally particularly supplies the ultimate affirmation that each one points of the launch car and spacecraft are totally suitable.
During launch, the spacecraft experiences a variety of mechanical forces, vibrations, temperature modifications, and electromagnetic radiation. All technical evaluations carried out by Arianespace on the mission’s key points, together with the launch trajectory and payload separation, have proven constructive outcomes.
“We are thrilled to have passed this important step towards the launch of Webb and to have received the green light from Arianespace and NASA,” says Peter Rumler, ESA Webb challenge supervisor.
Webb would be the largest, strongest telescope ever launched into area. As a part of a global collaboration settlement, ESA is offering the observatory’s launch service utilizing the Ariane 5 launch car. Working with companions, ESA was accountable for the event and qualification of Ariane 5 diversifications for the Webb mission and for the procurement of the launch service.

Ariane 5 will ship the telescope immediately right into a precision switch orbit in the direction of its vacation spot, the second Lagrange level (L2). After separation from the launcher, Webb will proceed its 4-week lengthy journey to L2 alone. L2 is 4 occasions farther away than the Moon, 1.5 million km from Earth within the route away from the Sun.
Mission evaluation consultants at ESA helped to compute the launch window, a posh subject as a result of it entails making certain that Webb might be inserted into its goal orbit and on the identical time the Ariane 5 higher stage will safely escape from Earth.
The telescope will observe the Universe within the close to-infrared and mid-infrared – at wavelengths longer than seen mild. To achieve this, it carries a set of state-of-the-artwork cameras, spectrographs and coronagraphs.
ESA performs an important function within the Webb mission. Aside from procuring the Ariane 5 launcher and launch providers, ESA is contributing the NIRSpec instrument and a 50% share of the MIRI instrument, in addition to personnel to help mission operations.
Webb is a global partnership between NASA, ESA and the Canadian Space Agency (CSA). Webb’s companions are working in the direction of the launch readiness date of 31 October 2021. The exact launch date following 31 October relies on the spaceport’s launch schedule and will likely be finalised nearer to the launch readiness date.
Detailed details about the Webb mission might be present in our launch package.
