A reader writes: "The US is going to spend $40+ billion to put people on the moon even though its a total waste of money since robots could do a better job. Care to guess the real reason for spending all that money? I bet it is just so the US can claim to have put a woman on the moon first, and the first black man, the first oriental, the first gay man, the first lesbian, etc. It will be a real rainbow coalition, I'm sure." Methinks he has a point!
