The European space Agency announced the final signing of the contract with Arianespace. The latter is obliged to provide the launch vehicle Ariane 5, which will put a Space telescope named the James Webb (JWST) to orbit the Earth. The launch telescope will be carried out from the launch site of Kourou, located in French Guiana, in October 2018.
After its launch, the JWST telescope will reveal before mankind new possibilities to study a variety of astronomical events. Among its objectives, for example, will find a relic of objects that could relate to the early formation of the Universe. This will eventually allow scientists to trace the evolution of galaxies from their earliest appearance to complete the formation.
In addition, the telescope will be a tool for discovering distant exoplanets, but also will witness the birth of new planets and stars. The scientific module of the JWST telescope currently going through a phase of testing, the first part of mirrors of the telescope have recently been successfully established in sterile hangar space flight Center Goddard.
In order for JWST to be able to make a real revolution in space research, European space Agency should assure that its output on a selected orbit, which is located at a distance of 1.5 million kilometers from Earth with the not shiny side.
To address this issue, ESA would rely on the years of experience of launching rockets since the 1980-ies. The carrier rocket Ariane 5, which will play an important role in this space mission, it combines the combination of two rocket engines on solid fuel and primary level with the engine on liquid fuel.
For safe delivery of JWST on-orbit spacecraft, including its mirrors, representing 18 hexagonal parts and which is essentially the most expensive part of the telescope, it is necessary prior to loading the missile on to fold like origami. As soon as the telescope gets to the right place, the mirror section is going to dissolve into one a 6.5-meter mirror.
Among other requirements signed between ESA and Arianespace the contract contains a paragraph on the additional construction of a new cleanroom, which will be the preparation and installation of the telescope inside the cargo ship. This is a precaution against accidental exposure to external sources of pollution that can damage the incredibly sensitive mirrors and other vital equipment of the telescope.
