''Lunokhod 2'' operated for about four months, and the original estimate was that it covered {{convert|37|km|mi|abbr=on}} of terrain, including hilly upland areas and rilles, and sent back 86 panoramic images and over 80,000 TV pictures.<ref name=2004Lunokhod2Airandspace/><ref name=2012Lunokhod2Register>{{cite web|title=New NASA snap of game developer's electric cart FOUND ON MOON: Probe in low pass over Garriott's radioactive tub-rover |url=https://www.theregister.co.uk/2012/03/16/moon_detailed_pic_landing_site_rover/ |author=Lewis Page |website=[[The Register]] |date=March 16, 2012 |access-date=May 25, 2013}}</ref><ref name=2012Lunokhod2Revisted>{{cite news |title=Lunokhod 2 Revisited |url=http://lroc.sese.asu.edu/news/?archives/537-Lunokhod-2-Revisited.html |publisher=NASA |date=March 13, 2012 |access-date=May 25, 2013}}</ref> Many mechanical tests of the surface, laser ranging measurements, and other experiments were completed during this time.
