摘要
The Next Generation Sky Survey (NGSS) is a Medium Explorer currently in Phase A study, with launch planned for 2007. NGSS will map the entire sky with unprecedented sensitivity from 3.5 to 23 microns. With over 500,000 times the sensitivity of COBE at 3.5 and 4.7 microns, and a thousand times that of IRAS at 12 and 25 microns, NGSS will establish an essential database for testing theories of the origins of planets, stars, and galaxies, and is the necessary precursor for NGST. The science objectives of NGSS include finding the most luminous galaxies in the universe, and the closest stars to the gun. NGSS will achieve these dramatic advances while minimizing mission cost and risk by using flight-proven technology for its spacecraft bus components and cryogenic instrument, as well as 2MASS data processing software.
