In terms of size (20.2×14.2 m), JWST is the largest space telescope in history. Source: NASA Largest space telescope in history A full-size JWST model on the territory of the Space Center named after Goddard. 258 companies, government organizations and scientific institutions (142 from the USA, 104 from Europe and 12 from Canada) contributed to the creation of JWST. In total, several thousand scientists and engineers from 15 countries of the world were involved in the project. The space agencies of Europe and Canada were also actively involved in the creation of the telescope. JWST - International projectĭespite the fact that NASA is the main “financier” of JWST, this is not a purely American project. ![]() The manufacture of the last components of the telescope was completed in 2016, they were first combined into a single unit in 2019. The preliminary design of the new telescope was agreed in 2008, and the final approval of the project took place in 2010. Production of the first JWST components began in 2004. In the future, the project underwent many serious metamorphoses and received a new name - in honor of NASA administrator James Webb, who held this position from 1961 to 1968. However, it quickly became obvious that this figure was overly optimistic. Initially, it was supposed to be equipped with an eight-meter mirror, and they hoped to spend only USD 500 million on the construction of the device. The origins of JWST date back to the mid-1990s, when NASA began developing a next-generation infrared telescope project called NGST (Next Generation Space Telescope).

The Ariane 5 rocket will send into orbit the James Webb Telescope (JWST) - the most complex and expensive space observatory of all time. ![]() Very soon, one of the most important launches in recent years will take place from the Kourou cosmodrome in French Guiana.
