'''[[Surveyor 7]]''' was launched on January 7, 1968, landing on the [[lunar surface]] on January 10, 1968, on the outer rim of the [[Tycho (lunar crater)|crater Tycho]]. Operations of the spacecraft began shortly after the soft landing. On January 20, while the craft was still in daylight, the TV camera clearly saw two laser beams aimed at it from the night side of the crescent Earth, one from Kitt Peak National Observatory, Tucson, Arizona, and the other at Table Mountain at Wrightwood, California.<ref>{{cite web |title=Boeing: Satellite Development Center - Scientific Exploration - Surveyor |url=http://www.boeing.com/defense-space/space/bss/factsheets/scientific/surveyor/surveyor.html |url-status=dead |archive-url=https://web.archive.org/web/20100207072958/http://boeing.com/defense-space/space/bss/factsheets/scientific/surveyor/surveyor.html |archive-date=2010-02-07 |access-date=2010-03-31}} Notes on the laser experiment.</ref><ref>[http://www.w7ftt.net/laser2.html] photo of the beam from the 2-watt green argon Hughes laser at Table Mountain</ref>

Operations on the second lunar day occurred from February 12 to 21, 1968. The mission objectives were fully satisfied by the spacecraft operations. Battery damage was suffered during the first lunar night and transmission contact was subsequently sporadic. Contact with Surveyor 7 was lost on February 21, 1968.<ref>{{cite web |date=28 November 2017 |title=Surveyor VII |url=https://www.lpl.arizona.edu/sic/surveyor/7 |access-date=11 April 2021 |website=University of Arizona Lunar and Planetary Laboratory}}</ref>
