It is about the size of a phone booth and looks unassuming from:.’s new super eye for the successor of the space telescope “Hubble”
Astrium employees of the company working on the . Ferigstellung of “Near Infrared” (photo: picture alliance / dpa) “Near Infrared” (Near Infrared Spectrograph) – this is the miracle of space technology – is to look deeper into space than the space telescope “Hubble” and deliver images of distant celestial bodies. The 230-pound spectrometer developed by the aerospace company Astrium recorded and analyzed weakest radiation of the first galaxies that formed in the universe. On Friday, the 160 million euro expensive super eye was presented before transportation to NASA in Taufkirchen near Munich.
“Near Infrared” can detect up to 100 celestial objects like galaxies or stars simultaneously. EADS Astrium CEO Eric Beranger called it at the handover of the European Space Agency ESA, a particular challenge, the spectrometer under normal conditions of operation in microgravity and at minus 235 degrees Celsius to build. “Today we see our baby,” Beranger said to NASA’s representative Eric Smith, who is responsible for the new space telescope “James Webb”. The ESA is the next NASA and the Canadian Space Agency CSA one of the three project partners.
answers to previously unasked questions
The spectrometer is one of four scientific instruments in the telescope. “Near Infrared” is to work up to ten years in space, as it was said at the presentation. 70 people were involved in development and construction. From planning to completion passed nine years. Until five years the new space telescope will be placed into orbit. But on now, EADS Astrium CEO Beranger are confident to “get out of” Near Infrared “answers to questions that are not yet even today.”

Astrium was also involved in the development of a camera with a spectrograph for the mid-infrared range, which will also be installed in “James Webb”. “MIRI” (Mid-Infrared Instrument) has been delivered to NASA in 2012. Esa’s director Alvaro Giménez lifted the European role that “to provide the best possible tools to enable the scientists to find out the best possible knowledge about the universe.” Eric Smith of NASA said that the scientific equipment would now be tested in the U.S. through its paces.
2018 is the “James Webb Space Telescope” (JWST) – are brought into space – named after a former NASA director. In a 1.5 million km from Earth orbit all phases of the creation of the universe to be explored by the first light after the Big Bang to the formation of planetary systems in our galaxy. This is made possible by the huge primary mirror with 18 hexagonal segments – the largest telescope in space, according to Astrium -., And the four highly sensitive instruments on board
