Actually sending people to space seems like much less interesting endeavor to me. We are intelligent, but very limited in our senses and abilities. Where can we really send humans? Moon, Mars maybe, orbit of Mercury/Venus? We also probably want to get them back, so these missions will be complicated by the fact that we don't like to throw away highly trained specialists. What can people do there that is not possible with robots?
