Space Telescope's primary mirror segments are prepared to begin final cryogenic testing at NASA's Marshall Space Flight Center in Huntsville, Ala. 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.
