Overview LSST’s mission is to build a well-understood system that provides a vast astronomical dataset for unprecedented discovery of the deep and dynamic universe. #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 2
Large Synoptic Survey Telescope A ground based 8.4m optical telescope Located in Chile on Cerro Pachón Site construction began April 2015 10 year survey starting 2022 Construction budget of US$671,000,000 Total Solar Eclipse over Cerro Pachon, July 2, 2019 Photo: K. Reil LSST/DOE/SLAC #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 3
Four Science Goals #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 5
LSST’s survey will be a 10-year log of half the sky LSST will image the entire Southern sky (18k sq deg) every few nights, taking an image every ~40 seconds, for 10 years. The result: an 825-frame 3.5 degrees movie in 6-filter technicolor of every (Full moon is 0.5 degrees) object present #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 6

Science themes Online investigations for formal education. • Surveying the Solar System : Students make observations of newly-discovered solar system objects using an orbit visualizer to determine the object type. • Hazardous Asteroids : Students evaluate the potential threat of an Earth impact by making repeated observations of a newly- discovered Near-Earth Object. #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 13
Data Product Categories #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 14
Data Rights & Data Access − Alert stream immediately public (60 seconds after observation) − Small bodies data -> Minor Planet Center (MPC) − All data public after two years − Data rights for in-kind contributors: – Funding agencies (NSF and DOE) have committed to fully support LSST operations BUT have given guidance to LSST to seek international partners. • LSST has produced high level models/menu of options for in-kind operations offsets . • Host of “really good to have” added value options being considered #ranpalgill EPSC-DPS Joint Meeting 2019 • Geneva, Switzerland • 19 September, 2019 15
