  1. VIRTUAL OBSERVATORIES of the FUTURE14-16 June 2000Caltech Solar System Surveys Steven H. Pravdo Jet Propulsion Laboratory

  2. Solar System SurveysGoals • Discover > 90% of the > 1km Near-Earth Asteroids (NEAs) by 2010 • Measure directly the number of Kuiper Belt Objects down to the typical size of cometary nuclei (a few km) • Enable physical characterization of asteroids and comets

  3. Solar System SurveysProjects • Near-Earth Asteroid Tracking -NEAT (NASA/JPL/USAFRL) • LINEAR (MIT-LL/USAF) • LONEOS--Lowell Observatory • Catalina (UA) • Spacewatch (UA) • TAOS (Acad. Sin., IA, LLNL)

  4. Solar System SurveysData • Telescopes Daily Data (GB) Archive/Access • NEAT 1.2-m (2) 25-100 Yes • LINEAR 1.0-m (2) 70 None • LONEOS 0.6-m ? ? • Catalina 0.4, 0.7-m 8 None…but • Spacewatch 0.9,1.8-m 13 None…but • TAOS 0.5-m (3) 21 None…but

  5. SkyMorph: 3-D Sky Catalog Description • A World-Wide-Web-accessible catalog of celestial images from the Near-Earth Asteroid Tracking (NEAT) database • http:/skys.gsfc.nasa.gov/skymorph/skymorph.html • Images and objects catalogs • Features position AND time information to study variable intensity and moving objects

  17. SkyMorph: 3-D Sky CatalogPLANS • Two new 1.2-m telescopes come into NEAT service. MSSS 1.2-m now operational. Palomar Oschin 1.2-m scheduled to come online in late 2000--limiting V ~ 20 mag • Sky coverage/data rate increase by factor of ~9 • Object catalog, merged and permanent, with improved utilities • Moving Target Detection temporal baseline extended with other online catalogs
