I remember having read this quite a while ago and I believe it is a Bradbury story, so I hope to get an answer on that. The story was about some astronauts landing on a foreign planet, but while searching it, they got killed one after another by traps and stuff of this kind, and then eventually were replaced by andriod versions of them. Does that sound familiar to anyone? I'm looking forward to your answers! Thank you!
