During his talk on whether robots or humans are the best choice for space flight, Roger Launius kept making the point that humans are designed from an evolutionary perspective for a very specific climate. That is one g of gravity at comfortable temperature. The only place that meets these requirements is sea level here on earth. Any other environment will produce many challenges for surviving, but us as modern humans have found ways to deal with these and have been for thousands of years. With proper shelter and clothing the inhabitable can become habitual, when the right elements are kept out. On earth, this is easy for us to think about, we know about most of the elements of nature that will kill us and readily avoid them. In space, we are presented with a whole new set of extraterrestrial challenges to keep people alive. Low gravity, unfiltered solar radiation, and even the dust on surface of planets will kill humans in the long run. There are measures that astronauts can take to minimize their effects, but they will always be there. The longest time a human had spent in space is a little over a year, about 438 days. On a human scale, this is a long time, a lot can happen in a year, but on a universal scale this is a tiny amount of time. Traveling to the next closest planet, Mars, would take as long as the longest time a person has spent it space. Once there they would be a year away from any help from Earth. With all the potential health problems and logistical difficulties of getting there, a trip to Mars might be out of the question if we plan on the scientists returning to earth. In space travel, the scientific exploration should not be compromised by human frailty. If worrying about the scientists returning becomes the priority, science takes a back seat to this. This is why I think robots are the logical choice at this point in our exploration of space. While it would be cool to put a person on Mars, is it really worth it? We advances in robotics and computer science, we can do more than ever before without leaving the safety of our atmosphere. The problem is robots will never have the same reasoning capabilities as a living person. Everything a robot knows, has been programmed into it by a person at an earlier time. With a 12 minute delay for any information coming from or going to mars, controlling a vehicle remotely is almost out of the question. The robot must be able to analyze its environment and make decisions accordingly. On one hand, the human can think rationally and make unforeseen decisions, on the other a robot does not need any of the life support systems. For the near future, it seems that space exploration will be a human/nature relationship where the slash is the robot, as we experience the universe outside of our world through the lens of technology.
