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 movie in 6-filter technicolor of every

bject present

3.5 degrees

(Full moon is 0.5 degrees)

Science themes Online investigations for formal education.

Surveying the Solar System: Students make
bservations 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.

− 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

perations BUT have given guidance to LSST to seek international

partners.

LSST has produced high level models/menu of options for in-kind
perations offsets.
Host of “really good to have” added value options being

considered
