■Class discussion: What are the biggest hazards for people spending a long time in space? Should we send people to Mars? Why or why not? Would you want to go? When do you think a manned mission to Mars could take place? Should such a mission involve many nations sharing the costs, risks and discoveries? Could nations set aside their rivalries to mount space missions? What could manned missions do that unmanned missions can't? Are robots much better suited to space exploration than people?
