An 8.4-m wide-field telescope at an altitude of 2680 m on Cerro Pachón, Chile, that will repeatedly survey the entire visible sky every three nights. Its images, each covering a field of view 3°.5 across, will be recorded by a digital camera with 3.2 billion pixels, each exposure lasting 15 seconds. They will be valuable for discovering and following objects such as variable stars, novae and supernovae, comets, near-Earth objects, and Kuiper Belt objects, as well as for mapping the distribution of remote galaxies. The data will be made publicly available via the Internet. The telescope is owned and operated by the LSST Corporation, a consortium of American and overseas universities, observatories, and research institutions with its headquarters in Tucson, Arizona. LSST is scheduled to begin operation in 2023.
