PIX4645744: James Webb Space Telescope Mirrors (JWST) - Testing of the JWST's mirrors - Six of the 18 JWST (James Webb Space Telescope) mirrors seen at Nasa's Marshall Space Center. These mirrors will be tested there to ensure they will withstand the extreme temperatures of space vacuum. The JWST will replace the Hubble Space Telescope in 2014. Equipped with a 6.5 m mirror, he will observe the universe mainly in infrared. Six of the 18 James Webb Space Telescope mirror segments are being moved into the X - ray and Cryogenic Facility, or XRCF, at Nasa's Marshall Space Flight Center in Huntsville, Ala., to eventually experience temperatures dipping to a chilling - 414 degrees Fahrenheit to ensure they can withstand the extreme space environments. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures. Marshall's X - ray & Cryogenic Facility is the world's largest X - ray telescope test facility and a unique, cryogenic, clean room optical test location. The James Webb Space Telescope (JWST) is a large, infrared - optimized space telescope scheduled for launch in 2014. Equipped with a large mirror 6.5 meters (21.3 feet) in diameter, it will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy and will reside in an orbit about 1.5 million km (1 million miles) from the Earth / Bridgeman Images

PIX4645827: James Webb Space Telescope (JWST) - Artist view - The James Webb Space Telescope (JWST) - Artist view: The James Webb Space Telescope (JWST) will replace the Hubble Space Telescope in 2018. The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope scheduled for launch in 2018. Equipped with a large mirror 6.5 meters (21.3 feet) in diameter, it will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy and will reside in an orbit about 1.5 million km (1 million miles) from the Earth - The shaded side of the James Webb Space Telescope (JWST) as it may appear later this decade when it is observing from the Earth-Sun L2 point about 930 thousand miles from the Earth. Part of the Milky Way can be seen reflected in the 21-foot diameter mirror assembly. This assembly is composed of 18 hexagonal segments of gold-coated beryllium which combines to create a near-infrared light-collecting area of about 80 square feet (the Hubble Space Telescope has a collecting area of 48 square feet) - The JWST's sensitive optical elements are shaded from the perpetual sunlight via a “” parasol” consisting of multiple spaced layers of polyimide film. These layers act as a passive cooling barrier between the 185* F sunward side and the -388* F shaded side hosting the optics and sensors / Bridgeman Images

PIX4642742: A satellite is directed to a cemetery orbit - Reorbiting a spacecraft into a graveyard orbit - Artist's view of a satellite in geostationary orbit at the end of the mission directs to a cemetery orbit. In order to prevent possible collisions, the satellite must be placed 300 km above its initial orbit. In order to eliminate collision risk, GEO satellites should be moved out of the geostationary ring at the end of their mission. It is recommended that their orbit should be raised by about 300 km, which is considered a safe distance to avoid future interference with active GEO spacecraft / Bridgeman Images
PIX4642769: Space Debris: Meteosat type satellite - Space debris: Meteosat satellite - Artist's view of a Meteosat satellite when it is put into orbit. As with many satellites, orbit operations cause new space debris (ejection of covers, bolts...); in view of the dangerous increase in space debris, it is imperative to design cleaner satellites today (here a cover remains attached to the satellite). A measure against space debris is minimizing the number of objects released during spacecraft operations. Typical “” mission - related objects”” (MRO) include adapters used between two satellites in a dual launch, telescope covers, bolts, cast off yo - yo spinners, etc. Spacecraft designers and operators must design missions so that objects stay attached to the spacecraft and do not become additional space debris / Bridgeman Images
