Or at least sex appeal. I realize this because Anousheh Ansari is going into space as the first woman space tourist and she's hot. Hot in in that classy, powerful woman way, as opposed to Paris Hilton, who is mildy amusing on her best day and therefore not really hot.

But sending hot, sexy people suddenly makes space travel more interesting to the general public. Everyone wants to see what hot people are doing or even copy them. Because if you do what sexy people do, you're sexy too, right? Or at least sexier than that drab thing you call life.

Luckily, others have thought of this, as Madonna has been cleared for flight around 2008.

If only NASA was aware of these things.
