The Washington Post has an editorial on manned vs robotic Mars exploration by Robert Zubrin, president of the Mars Society. The erroneous idea that robots will eliminate human space travel seems to come up whenever a space mission is in the news and we've covered it before. Zubrin points out that while robots are useful, fun, and cheap ways of exploring, many of the tasks involved in looking for life would be much easier for a human explorer. And, regardless of how many robots are sent to Mars for exploration, humans will still go themselves eventually in order to live there.
