A traditional Chilean stone laying ceremony to celebrate the beginning of construction of the Large Synoptic Survey Telescope (LSST) was held on April 14, 2015 on a mountain peak in northern Chile. This marked the start of construction of the LSST, an 8 meter wide-field survey telescope that will image the entire visible sky a few times each week and provide an unprecedented amount of immediate information to the scientific community on a daily basis. The LSST is expected to see first light in 2019 and begin full operation in 2022.
