The National Aeronautics and Space Administration is inviting grant applications for research on Near-Earth Objects: asteroids or comet nuclei whose perihelia are less than 1.3 AU. NASA is committed to discovering all NEOs with diameters greater than or equal to approximately 1 km and to characterizing that population through determination of their orbital elements, with the goal of detecting more than 90 percent of this population as soon as possible. This program supports NEO investigations whose primary aim is to complete the inventory of the population of such NEOs.

DEADLINE: Notices of intent were due April 13; full proposals are due June 8. NASA will accept late notices of intent.
