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

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
SkyMorph: 3-D Sky CatalogMOVING TARGET DETECTIONHale-Bopp (21 June 1996) Toutatis (17 August 1996)
SkyMorph: 3-D Sky CatalogASTEROID FOLLOW-UPS • 1998 MQ images 1 hour apart on 19 July 1997
SkyMorph: 3-D Sky CatalogPOTENTIALLY HAZARDOUS ASTEROIDS • 1999 AN10 on DSS, 26 January 1955, found with SkyMorph Moving Target Detection
SkyMorph: 3-D Sky CatalogSUPERNOVA DISCOVERIES • 24 March 1998 and 18 February 1999 - SN 1999am
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
