The James Webb Space Telescope, the largest optical telescope in space, was launched on Christmas of last year. It is now in place at Lagrange Point #2—about 932,000 miles from Earth—and sending back detailed images of galaxies and planets. It will continue to use its three IR cameras to take images of celestial objects for its 5.5-year primary mission, its 10-year planned life and, hopefully, for its 20-year expected life.
The telescope is a collaboration between NASA and the European and Canadian space agencies. The main industrial partner is Northrup Grumman. The telescope is being operated by the Space Telescope Science Institute (STSci).
