galex telescope nasamauritania pronunciation sound

NASA cut off financial support for operations of GALEX in early February 2011 as it was ranked lower than other projects which were seeking a limited supply of funding. Each of the two detectors has a 65 millimeter diameter. Data from the GALEX spacecraft suggest that planets around cool dwarf stars may be subjected to intense flares.The galaxy UGC 1382 has been revealed to be far larger and stranger than previously thought. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. GALEX is will performing the first Space Ultraviolet sky survey.
The telescope is a 50-cm Modified Ritchey-Chretien with a rotating grism. GALEX uses the first ever UV light dichroic beam-splitter flown in space to direct photons to the Near UV (175-280 nanometers) and Far UV (135-174 nanometers) microchannel plate detectors. The target orbit is 670 km circular and inclined at 28.5 degrees to the equator. The circular field of view is 1.2 degrees in diameter and the angular resolution is ~4.5 arcsec. The spacecraft will be three-axis stabilized, with power coming from four fixed solar panels. Such observations would provide data how galaxies, the basic structures of our Universe, evolve and change.
GALEX has a planned 29 month mission, and is a part of the Small Explorers (SMEX) program. The spacecraft bus is from Orbital Sciences Corporation based on OrbView 4. Caltech. Led by the California Institute of Technology, GALEX was to conduct several first-of-a-kind sky surveys, including an extra-galactic ultraviolet all-sky survey.The Galaxy Evolution Explorer (GALEX) is an orbiting space ultraviolet telescope, which explores the origin and evolution of galaxies, and the origins of stars and heavy elements over the redshift range of z between 0 and 2. Such observations would provide data how galaxies, the basic structures of our Universe, evolve and change. It was finally switched off on 28 June 2013, following an extra tenth year of observing funded by GALEX uses the first ever UV light dichroic beam-splitter flown in space to direct photons to the Near UV (175-280 nanometers) and Far UV (135-174 nanometers) microchannel plate detectors. As well, GALEX will perform three spectroscopic surveys over the 135-300 nanometer band. A Pegasus rocket launched GALEX into orbit at 8 a.m. EDT on April 28th, 2003. As well, GALEX will perform three spectroscopic surveys over the 135-300 nanometer band. GALEX has a planned 29 month mission, and is a part of the Small Explorers (SMEX) program. Launched 2003. NASA sent a decommission command to the space telescope Friday.NASA is sending a reliable servant into a retirement that will end with a fiery re-entry into Earth's atmosphere in about 65 years. The spacecraft bus is from Orbital Sciences Corporation based on OrbView 4. Five imaging surveys in each of two bands (1350-1750 Å and 1750-2800 Å) range from an all-sky survey (limit m AB ~20-21) to an ultra-deep survey of 4 square degrees (limit m AB Air dropped in Mayport DZ. NASA has turned off a decade-old space telescope, a year after loaning the orbiting instrument to a university that operated it with private funding. Much delayed launch (from January 19, May 19, July 16, 21 and 30, August 14 and October 17, 2002; January 27, March 25 and 30, April 15 and 26 2003).

The Galaxy Evolution Explorer (GALEX) was an orbiting space telescope that was to observe galaxies in ultraviolet wavelengths.
