1 VIRTUAL OBSERVATORIES of the FUTURE 14-16 June 2000 Caltech Solar System Surveys Steven H. Pravdo Jet Propulsion Laboratory

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

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

6 SkyMorph: 3-D Sky Catalog SYSTEM ARCHITECTURE

7 SkyMorph: 3-D Sky Catalog IMAGE PROCESSING FLOW DIAGRAM

8 SkyMorph: 3-D Sky Catalog SCIENCE DATA

9 SkyMorph: 3-D Sky Catalog DATA INGESTION

10 SkyMorph: 3-D Sky Catalog CURRENT SKY COVERAGE

11 SkyMorph: 3-D Sky Catalog MOVING TARGET DETECTION Hale-Bopp (21 June 1996) Toutatis (17 August 1996)

12 SkyMorph: 3-D Sky Catalog ASTEROID FOLLOW-UPS 1998 MQ images 1 hour apart on 19 July 1997

13 SkyMorph: 3-D Sky Catalog POTENTIALLY HAZARDOUS ASTEROIDS 1999 AN 10 on DSS, 26 January 1955, found with SkyMorph Moving Target Detection

14 SkyMorph: 3-D Sky Catalog NEARBY STAR PROPER MOTION

15 SkyMorph: 3-D Sky Catalog SUPERNOVA DISCOVERIES 24 March 1998 and 18 February 1999 - SN 1999am

16 SkyMorph: 3-D Sky Catalog QUASAR LIGHT CURVE

17 SkyMorph: 3-D Sky Catalog PLANS 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
