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

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.

  • 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
