The LSST design is driven by four science themes: dark energy, Galactic structure, transient objects, and the search for near-Earth asteroids. The LSST will carry out a ten-year imaging survey of 20,000 sq.deg. of the sky in six broad optical bands, with a deep stack reaching r 27.5 (5 sigma, point source). The current design, with an 8.4m (6.7m effective) primary mirror and a 9.6 square degree field of view, will allow about 10,000 square degrees of sky to be imaged to an effective depth of r=24.5 every three nights. The resulting petabytes of data will be made available to the US and Chilean communities for scientific investigations ranging from the properties of near-Earth asteroids, to characterizations of dark energy from strong and weak lensing, galaxy clustering, and distant supernovae. Eleven LSST Science Collaborations are actively laying the groundwork for first light: working on image analysis algorithms and database design, exploring cadence choices, developing commissioning plans, and outlining scientific opportunities. These Collaborations have over 200 members to date, with membership open to the US community via an application process administered by NOAO.
