Person2: You should be optimistic about this . Things have taken a good turn . You should remember that less than two centuries ago the dangers of train travel seemed similarly terrible .
Person1: But is it possible that travelers could be hit by meteors ?
Person2: It's once in blue moon .
Person1: What do you think is the real danger man faced in space ?
Person2: The main one is radiation . There are two sorts of radiation man must fear in space . The first is radiation from the sun , and this is particularly dangerous when the sun is very active and explosions are occurring on its surface . The second , less harmful , comes from the so-called Van Allen Belts .
