NASA's Next Big Thing: The James Webb Telescope
The James Webb Space Telescope will replace the Hubble as the premier space observatory of the next decade, serving thousands of astronomers worldwide.

James Webb Telescope on Display in Germany

A full-scale model of the James Webb Space Telescope was built by the prime contractor, Northrop Grumman, to provide a better understanding of the size, scale and complexity of this satellite. The model is constructed mainly of aluminum and steel, weighs 12,000 lb., and is approximately 80 feet long, 40 feet wide and 40 feet tall. The model requires 2 trucks to ship and assembly takes a crew of 12 approximately four days.

Assembling the Mirrors

Six of the 18 mirror segments are prepped to move into the X-ray and Cryogenic Facility at NASA's Marshall Space Flight Center in Huntsville, Ala., to eventually experience temperatures dipping to a chilling -414 degrees Fahrenheit -- ensuring they can withstand the extreme space environments. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures.
