When is a space mission too expensive to fly? "It's a question much in the mind of proponents of robotic exploration, who can point to lower cost as one excellent reason to leave human crews out of our deep space missions. But robotic missions can suffer the same fate as human ones, with technology advances like miniaturization exploited not to pack more instruments on board but to reduce costs."
