In addition to observations of natural phenomena, Lick was also the location of the first [[Lunar Laser Ranging experiment|laser range-finding]] observation of the [[Apollo 11]] reflector, although this was only for confirmation purposes and no ongoing range-finding work was performed.<ref>{{cite web |url=http://www.csr.utexas.edu/mlrs/history.html |title=History of Laser Ranging |website=University of Texas Center for Space Research |access-date=January 2, 2019 }}</ref>
