===Lunokhod 201===
After years of secret engineering development and training, the first Lunokhod (vehicle 8ЕЛ№201) was launched on February 19, 1969. Within a few seconds the rocket disintegrated and the first Lunokhod was lost. The rest of the world did not learn of the rocket's valuable payload until years later.<ref name="autogenerated1">{{cite episode|title=Tank on the Moon |series=The Nature of Things with David Suzuki |network=CBC-TV |airdate=December 6, 2007 |url=http://www.cbc.ca/natureofthings/magazine2.html |url-status=dead |archive-url=https://web.archive.org/web/20081226123643/http://www.cbc.ca/natureofthings/magazine2.html |archive-date=December 26, 2008 }}</ref> The failure resulted in the radioactive heat source, [[polonium 210]], being spread over a large region of Russia.<ref name="eneryspace">{{cite web|url=http://www.spacesafetymagazine.com/2014/01/16/energy-resources-space-missions/ |title=Energy Resources for Space Missions |first=Göktuğ |last=Karacalıoğlu |work=Space Safety Magazine |date=January 6, 2014 |access-date=January 18, 2014}}</ref>
