I crossed another planet off my list while I was at the local university observatory on Friday night. Mercury is up above the horizon after sunset, and visible through telescopes and the naked eye. By my count, that just leaves Uranus or Neptune (I can't recall which, but I think it's Neptune) left for me to see with my own two eyes.
The fact that astronomers thought they saw surface features on other bodies when their telescopes weren't all that much more powerful than those I was looking through...really says something about human psychology, most likely.
Tomorrow, it's back to the problem of getting people out there.
