[4.07] The Next Generation Sky Survey

E. Wright (UCLA), NGSS Team

The Next Generation Sky Survey (NGSS) is an experiment designed to provide an all sky survey of unprecedented sensitivity in the mid-IR band from 3.5 to 23 \mum.

Scientific objectives to be addressed by NGSS include: (1) The nature of and evolutionary history of Ultra-Luminous InfraRed Galaxies: NGSS should find the most luminous galaxy in the Universe. (2) The old stellar content of normal galaxies: NGSS should provide 3.5 \mum photometry on 109 galaxies with a median redshift greater than 0.5. (3) The faintest, coldest stars: NGSS is sensitive to old, cold brown dwarf stars with temperatures below 1000 K. NGSS should discover the closest star to the Sun. (4) Solar System: NGSS should measure radiometric diameters and albedos for almost all known asteroids, and discover 500,000 new asteroids.

NGSS will use a 50 cm cryogenic telescope, 10242 infrared arrays, and observe from a IRAS/COBE style sun-synchronous high inclination low Earth orbit.

NGSS was proposed as a MIDEX in 1998 and selected for a Phase A study in 1999, but not selected for flight. NGSS will be reproposed in 2001.
