Telescope united

摘要

The two halves of NASA's James Webb Space Telescope (JWST) have been joined together for the first time, marking a significant step in the mammoth scientific project.Engineers and technicians used a crane at Northrop Grumman's facilities in Redondo Beach, California, to assemble the two halves of the space telescope, which has been in development since the 1990s. Once launched, the JWST will be stationed at the L2 Lagrangian point, exploringthe cosmos predominantly using infrared light.This will enable it to observe high redshift objects that are too old or distant for the Hubble telescope to see.The mission has a planned launch date of March 2021.
