On August 2, 1971, near the end of their final excursion on the Moon, Apollo 15 astronauts David Scott and James Irwin placed a memorial plaque on the lunar surface in honour of 14 deceased astronauts and cosmonauts. Beside it, they placed a small aluminium sculpture known as the Fallen Astronaut.
The plaque bears the names of Charles Bassett II, Pavel Belyayev, Roger Chaffee, Georgi Dobrovolski, Theodore Freeman, Yuri Gagarin, Edward Givens Jr., Virgil Grissom, Vladimir Komarov, Viktor Patsayev, Elliot See Jr., Vladislav Volkov, Edward White II and Clifton Williams Jr.
