NASA launched the James Webb Space Telescope has successfully unfolded its gimbaled antenna assembly with the data dish that will beam back information about the earliest stars in the universe. Webb will take 29 days to reach the Lagrange Point 2 (L2) that is 1 million miles (1.6 kilometers) from the launch base on Earth. The Webb telescope, costing $10 billion, is considered the successor to Hubble. The upgrade is significant: Hubble could pick up only visible and ultraviolet light. James Webb Space Telescope (JWST) uses infrared detectors and spectroscopes.
Developed by NASA, with contributions by European Space Agency and Canadian Space Agency, with manufacturers Northrop Grumman, and Ball Aerospace who built the primary mirror, the new telescope is named after James E. Webb, NASA administrator from 1961-1968 who played a pivotal role in the Apollo lunar program, directing advances to serve education and science. It is interesting to note that Webb was not a scientist, but an attorney and business leader who had served in the public and private sectors. Webb almost turned down the job, but President John F. Kennedy convinced him that he had the right skills for a broad program with significant missions. You can listen to the audio of President John F. Kennedy and James Webb as they discuss human spaceflight: here.
