Space Fact, Space Fiction

Space.com has this interesting little quiz that presents 10 statements about science, astronomy, and technology, and you get to decide if each is fact or fiction. I got 9 out of 10, not too shabby for someone who hasn't picked up a science book in a year or two.
eMail this entry!
Darn it, got the ion drive question wrong. I thought that one was still being developed. It's cool to see that it's worked twice.
I missed the "gravity in deep space" one. The explanation kinda raised an eyebrow because I don't consider orbiting bodies around a star as "deep space". Of course there is gonna be gravity within a solar system, thats why they're called "orbits". I consider "deep space" to be waaaayyyy beyond the gravitational influence of any star. Either it's me or the question is worded poorly.
Stars are held together by gravity to make galaxies, Galaxies have gravitational attractions. Gravity from any point source will get weaker as you move away, but it never goe to zero and the universe is has many objects. Even dust clouds exert gravitational forces.
Gack-late night typing-goes not goe and has-not is has. Sorry.
8 of 10. damn ion engine question, along with the binary star one.
9/10 got the primitive life one wrong, I thought I had heard something about primitive cells on europa or something like that
I got the hard ones and missed the easiest one on the test!
