JWST: Mirrors and Masked Men
http://apod.nasa.gov/apod/ap100312.html
The James Webb Space Telescope is an international effort led by NASA. It was named after NASA's second administrator. It is an infrared space telescope and will replace some of Hubble's functions. It is intended to be able to see some of the most distant objects in the universe, and has four main goals: to find some of the original light created by the first galaxies and stars after the Big Bang, to study the formation of galaxies, to study the formation of stars, and to study planetary systems and the origins of life. The JWST is planned to be launched an an Ariane 5 rocket in 2014. It will orbit the Sun between the Sun and Earth, synchronized with Earth's orbit. The telescope has a 21.3-foot primary mirror with eighteen segments. The technicians in the picture are preparing some of the mirror segments.
