divIt is about the size of a phone booth and looks unassuming from: the new ‘super-eye’ for the successor of the space telescope “Hubble”. “Near Infrared” (Near Infrared Spectrograph) – so is the marvel of space technology – is to look deeper into space 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. Now 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.
70 employees involved in the development
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.
Only in five years, the new space telescope will be put into space. But EADS Astrium CEO Beranger was already confident “to get by” 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 director Alvaro Giménez lifted the European role out, “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.
brighten dark time after the Big Bang
The “James Webb Space Telescope” (“JWST”) is more than any other telescope to look back into the past and thereby lighten the dark time after the Big Bang, when there were no stars and galaxies were.
The text after the former director of NASA’s James Webb (1961-1968) named his outpost telescope will receive more than 1.5 million kilometers from Earth. A protective coat, as big as a tennis court, intercepts the sun rays and the infrared radiation from Earth and Moon.
text as little as possible to the sharp eyes of the telescope irritate, so that they can look back to the beginning – to 200 million years after the “Big Bang”, the Big Bang. Mainly on two issues, the astronomers hope to answer by “James Webb” How did it all begin? Is there life elsewhere?
The telescope is a technical masterpiece full of new inventions. So that the pictures are razor sharp and not blurred, for example, a tolerance must be maintained during the movement, which is a thousandth of a human hair.
With an Ariane 5 rocket of the European Space Agency ESA, it is to be launched into space in 2018, and then automatically unfold.
