I don't think it's a secret that I'm a nut for space exploration.

I'm still torn between a trip to Mars or a base on the Moon as our next step into space, but anything that moves us in that direction is great.  Recently, six volunteers entered an isolation chamber in Russia to study the long-term effects of living in close quarters in preparation for a trip to Mars.  I think this is cool for several reasons.  First, of course, the advancement of science.  Second, it means we may be getting closer to an actual trip to Mars.  And, third, because of all the potential science-fiction stories and movies that will result.
