NASA plans to send a 400,000 kg manned spacecraft on a 30-month round trip to Mars as early as February, 2031. Cost estimates range from $20 billion to $450 billion; the mission would be the most complex technical feat ever attempted. Should humans go to Mars?
"My atheism, like that of Spinoza, is true piety toward the universe and denies only gods fashioned by men in their own image, to be servants of their human interests."
