Just one data point: I taught in an aerospace museum in the US from about 2005-2009. In our rocket history programs, we covered the ancient Chinese, Goddard, the V-2 program and Von Braun, and the competition between the Soviet and American space programs -- Sputnik, Laika, Ham, Gagarin, Tereshkova (and the 20 year lead she had on Sally Ride), and Armstrong (with Aldrin and Collins). I'd usually give the audience a chance to contribute the names. Almost everyone got Neil and Buzz, quite a few knew Gagarin, and the rest of the names were pretty hit-and-miss. The one personal note I liked to add: I got to meet half a dozen astronauts and cosmonauts (picking them up from the airport and bringing them to our museum for a conference). Every single one of them emphasized that, even as the two sides were competing and treating each other as mortal enemies, those who were actually going to space viewed one another as friends or even brothers.
