'''[[Surveyor 6]]''' was the first spacecraft planned to lift off from the Moon's surface.<ref>{{cite book |last1=Siddiqi |first1=Asif A. |url=https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |title=Beyond Earth: A Chronicle of Deep Space Exploration, 1958–2016 |publisher=NASA History Program Office |year=2018 |isbn=9781626830424 |edition=second |series=The NASA history series |location=Washington, DC |page=1 |lccn=2017059404 |id=SP2018-4041 |archive-url=https://web.archive.org/web/20190424211923/https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |archive-date=2019-04-24 |url-status=live}}</ref>

It was launched on November 7, 1967, and landed on November 10, 1967 in Sinus Medii (near the crash site of [[Surveyor 4]]). The successful completion of this mission satisfied the Surveyor program's obligation to the Apollo project.

Surveyor 6's engines were restarted and burned for 2.5 seconds in the first lunar liftoff on November 17 at 10:32 UTC. This created 150 lbf (700 N) of thrust and lifted the vehicle 12 feet (4 m) from the lunar surface. After moving west eight feet, (2.5 m) the spacecraft once again successfully soft landed and continued functioning as designed. On November 24, 1967, the spacecraft was shut down for the two-week lunar night. Contact was made on December 14, 1967, but no useful data was obtained.
