Large Synoptic Survey Telescope: Entering the Era of Petascale Optical
The Large Synoptic Survey Telescope (LSST;http://lsst.org) is a
planned, large-aperture, wide-field, ground-based telescope that will
survey half the sky every few nights in six optical bands from 320 to
1050 nm. It will explore a wide range of astrophysical questions,
ranging from discovering “killer” asteroids, to examining the nature of
The LSST will produce on average 15 terabytes of data per night,
yielding an (uncompressed) data set of over 100 petabytes at the end of
its 10-year mission. Dedicated HPC facilities will process the image
data in near real time, with full-dataset reprocessings on annual scale.
A sophisticated data management system will enable database queries from
individual users, as well as computationally intensive scientific
investigations that utilize the entire data set.
In this talk, I will give an overview of what LSST will deliver once
operational, review implications of LSST-sized data sets on astronomy in
the 2020s, and discuss how we as a community will need to prepare for
the upcoming age of petascale datasets.
