Russia and the U.S. define EVA differently. Russian cosmonauts are said to perform EVA any time they are in vacuum in a space suit. A U.S. astronaut must have at least his head outside his spacecraft before he is said to perform an EVA.
In this table, we apply the Russian definition to Russian EVAs, and the U.S. definition to U.S.EVAs.
