Although the task is well begun, the vast majority of NEOs remain to be found.2 In the past few years the annual rate of discovery of Earth crossers larger than 1 km has been at about 1% of the estimated remaining population.3 However, new CCD detection systems that are becoming available for dedicated search telescopes will permit an increase in the discovery rate by an order of magnitude. Three systems (Table 3.1)

Air Force, as an expansion of the NEAT project, will undertake a more intensive survey of NEOs in collaboration with NASA, using the U.S. Air Force's GEODSS satellite-tracking network upgraded with large-format CCD cameras.

Organizations such as the International Astronomical Union and COSPAR may have a role to play in this task. OBSERVATIONS NEEDED TO IDENTIFY OBJECTS OF HIGH SCIENTIFIC INTEREST The Space Studies Board has stated previously that reconnaissance and initial exploration of asteroids by spacecraft constitute a high-priority goal.5 Three classes of observations are required to identify targets of sufficient scientific interest to justify exploration by spacecraft: Identification, which includes detection and astrometry to determine orbits.

The added value provided by sample return is likely to be great, and the Space Studies Board and its committees have repeatedly noted that the return of asteroid samples for laboratory analysis will be necessary to meet the objectives of continuing solar system science.7 ~ The following ongoing or already approved spacecraft missions relate directly to the exploration of near-Earth objects:9 · Near-Earth Asteroid Rendezvous is the first of NASA's Discovery class and will be the first spacecraft to orbit an asteroid. The spacecraft flew by (253)
