 NEO Surveyor will carry out a five-year baseline survey to  ...

   (1) find at least two-thirds of the near-Earth objects larger than 
        140 meters (460 feet);
   (2) assess the overall threat posed by potential Earth impactors; 
   (3) assess the impact threat posed by comets; 
   (4) determine the orbits and physical characteristics of the discovered 
        objects

 The survey will operate from a northern halo orbit of the Sun-Earth L1 (inner)
 Lagrange point to include the population of objects nearer the Sun than Earth's
 orbit.

 Instruments
  One 50 cm (20 in) infrared telescope operating wide-field cameras at two 
  thermal infrared wavelength channels for a total wavelength range between 
  4 um and 10 um. Field of view is 11.9 degrees^2. 

  The spacecraft will have a sunshade and the detector will be passively cooled 
  to -243 degrees C. 

 SPACECRAFT TRAJECTORY:
  Preliminary planning trajectory from JPL navigation at launch-5 years.
