Space telescope WISE starts monitoring the near-Earth objects

NASA Space Telescope Wide-field Infrared Survey Explorer, or WISE, is designed to map the sky and the exploration of objects in space, spent its entire stock of refrigerant needed apparatus to maintain the low temperature detectors. However, this does not mean the end of the mission. NASA said that now this phone will not be able to observe distant objects, but can investigate such celestial bodies as hidden asteroids, comets and t n

The space agency announced today the launch of the mission NeoWISE, in which the unit will not be able to work in cryogenic conditions, but will continue to use their detectors for observation and research in the infrared.

"Two of the four infrared detectors will operate at higher temperatures, so we can use them to continue the hunt for asteroids and comets," — said Amy Mainzer, the astronomer NASA Jet Propulsion Laboratory in California.

The main task of the new mission is to find near-Earth objects that are hard to see in visible light. It is expected that in the regime NeoWISE telescope will last at least four months.

To date, WISE telescope has discovered 19 comets and more than 33,500 asteroids, including 120 near-Earth. Total Telescope has made more than 1.8 million images. WISE launched the device was in December 2009. In addition to comets and asteroids WISE also observed cool stars, called brown dwarfs, and takde hidden galaxies that are only visible to infrared light.

NASA noted that the continuation of the flight WISE — a victory for the scientific community. In May this year, the Supervisory Board recommend to stop NASA mission WISE, when she would spend reserves of liquid hydrogen. At the same time, senior U.S. astrophysical Committee stated that throwing in orbit working staff would be unwise and committed to continuing to work is $ 6.5 million, to the $ 320 million that has already been invested in the WISE.
