The Large Synoptic Survey Telescope is an 8-meter three-mirror anastigmat reflector telescope under construction on the El Peñón peak in Chile, having begun in 2014 with the aim of first light in 2020 and full operation in 2022. Forming the mirrors began in 2008.
It will have an especially wide field of view, with a 3.2 gigapixel camera that will take a 15-second exposure each 20 seconds. It is aimed at identifying transients, such as discovering small solar system objects and detecting supernovae, and gathering light curve data.
Given the amount of data produced, there will be a need for automated processing, leading to efforts to encourage development, such as the Photometric LSST Astronomical Time-series Classification Challenge (PLAsTiCC).
