On the perennial square-circling problem:
You never have enough time ... The pressure I felt as a professional field geologist on the moon was that of getting as much good information as I possibly could knowing that almost certainly, at least in the foreseeable future, I would not get to go back to that field area ... On the other hand there was a professional joy of moving to each new station and having the challenge of deciding what was the most productive thing one could do at that station, what were the best samples to take and to do it in the most efficient way possible.And on testing versus checking, I mean, on manned versus robotic missions:
The thing that humans bring to the table, whether they're working on the moon or working in the laboratory is the brain. The human brain is a magnificent qualitative supercomputer that can be trained, assimilate experience and reprogram itself almost instantaneously based on that experience and that training. Robots can't do that.
The Mars exploration rovers can do a wonderful job but it takes a much, much longer time to gather that kind of insight that a human gets almost instantaneously. A human also can understand almost instantaneously what's going to be important and what isn't ... You would make a serious mistake if you took human beings out of the exploration equation.I think I'm Schmitten.
