Who cares? It's just one guy. He didn't even really DO anything. He didn't invent the spaceship, he didn't build it or do anything of value. He just got on it, flew to the moon and came back. His contribution could have easily been made by anyone else in the space program. So what if he's dead?
I hear that they're going fake his burial in an elaborate set made to LOOK like a graveyard. edit: and there's plans for a wake, i hear tell - they're going to shoot a monkey into the sky on a rocket. not because the states needs another primate cosmonaut, but because Neil always got a kick out of it.
