We will continue to develop and conduct critical tests on the James Webb Space Telescope leading to its planned launch in 2018. As the successor to Hubble Space Telescope, James Webb will again revolutionize our understanding of the universe.
Pictured here: NASA engineer Ernie Wright looks on as the first six flight ready James Webb Space Telescope's primary mirror segments are prepped to begin final cryogenic testing at NASA's Marshall Space Flight Center.
This represents the first six of 18 segments that will form NASA's James Webb Space Telescope's primary mirror for space observations. Engineers began final round-the-clock cryogenic testing to confirm that the mirrors will respond as expected to the extreme temperatures of space prior to integration into the telescope's permanent housing structure.
