Space Exploration: Humans only

Can you believe it? Here it is April 5th and there's about an inch of snow on the ground where I live. Winter's trying to hang on. I should move to a warmer climate as I really like heat :-).

Nevertheless, I've been able to get out a number of days each month through the winter and ride my bike (road bike), but when the temperature is hovering around 37 degrees (~2.7 Celsius), it's not all that fun, especially with the wind chill factor. Hopefully it won't be too long until we get some hot summer weather, and then I'll be doing long bike rides and hiking.

As I mention in my previous post, I'm a strong proponent of space exploration, both robotic and human. Now the author of the article below (see link) favors manned exploration, not robotic. He makes some good points for it.
