The Launch and Deployment of the James Webb Space Telescope

The James Webb Space Telescope (JWST) is a space telescope developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). It is designed to replace the Hubble Space Telescope as NASA’s premier space observatory.

The JWST was launched on December 25, 2021, from the Guiana Space Centre in Kourou, French Guiana. It was carried into space by an Ariane 5 rocket. The telescope then began a six-month journey to its final destination, the second Lagrange point (L2), which is located about 1.5 million kilometers from Earth.

The JWST is the most complex and expensive space telescope ever built. It has a 6.5-meter (21.3-foot) primary mirror, which is made of gold-plated beryllium. The telescope also has four scientific instruments: a near-infrared camera (NIRCam), a mid-infrared instrument (MIRI), a near-infrared spectrograph (NIRSpec), and a tunable filter imager (TFI).

The JWST is designed to study the early universe, the formation of galaxies, and the evolution of stars and planets. It is also expected to provide new insights into the atmospheres of exoplanets and the search for life beyond Earth.

The deployment of the JWST was a complex and challenging process. The telescope’s sunshield, which is the size of a tennis court, had to be unfolded and deployed in space. The telescope’s primary mirror also had to be unfolded and aligned.

The JWST successfully completed its deployment on January 28, 2022. The telescope is now fully operational and is expected to begin science operations in June 2022.
