The Webb Space Telescope’s mirror has nearly seven times the area of the Hubble Space Telescope’s. In order to launch it into space, the mirror is made out of segments that will be folded up inside the rocket that carries it into orbit. At Marshall Space Flight Center, segments are being tested in the vacuum chamber to expose them to space temperatures.

“Behind the Webb” is a recurring video series from HubbleSite, home of the Hubble Space Telescope and the upcoming Webb Space Telescope. Join host Mary Estacion as she goes behind the scenes to watch the construction and testing of the parts that will make Webb the world’s most powerful infrared telescope.

Webb’s Challenge: Make It Big

The Webb Space Telescope will need to be extraordinarily cold in order to see the infrared light from the farthest reaches of the universe. Webb’s enormous sunshield will protect the telescope’s instruments from the Sun’s energy.
