The Smithsonian National Air and Space Museum's curator Cathleen Lewis and conservator Lisa Young answered a number of questions from the public via a Reddit AMA session yesterday. The topic? Spacesuits. They recently raised over $600,000 on Kickstarter for the conservation of Neil Armstrong's Apollo 11 suit, and now they've begun promoting the project. One of the most interesting tidbits they dropped is the difference between real spacesuits and movie props. The biggest inaccuracy for Lewis is the size of most movie versions' helmets: turns out Hollywood merely exaggerates them to get a clear view of the actors' faces. "If you look at actual Apollo bubble helmets and photographs of astronauts wearing them, you will see that they are actually tightly fitting," Lewis answered the user who asked about movie inaccuracies. "The diameter of the helmets is about 12 inches. No one with claustrophobia would be able to get beyond the initial helmet fit."
