9/10 Drat. Those durn binary systems…
Thought I remembered them saying they were too gravitationally unstable to keep & form planets…
10/10 I finally won someting.
There is some question that the Apollo astronauts may have contaminated the surveyor arm.
9/10 missed #2 about the bacteria :smack:
8/10, missed #2 and #7.
8/10, I feel so dumb. 
I got #2 and #7 wrong, just like dwc1970.
I thought that ion engines were just experimental and not actually used. I guess I’m an idiot.
But I knew the teleportation one. I had a good physics teacher in high school who actually did a little bit of quantum physics, and mentioned to us how some scientists “teleported” photons.
10/10 Where were the difficult questions?
8/10
I got
6 wrong for the same reason as Small Clanger and 9.
9/10. Like trupa, I thought I remembered reading that none of the known binary systems was organized in such a way that it would permit any sort of stable planetary orbit.
10/10!
Will they let me on the Shuttle now?
7/10, damn it all to hell.
Planets can exist in binary stars? And while I knew ion engines existed, I didn’t know we were actually using them.
I won’t mention the third one I got wrong. Let’s just say I was naive and let my enthusiasm cloud my judgement.
JPL’s website for Deep Space 1, which was the vehicle to very successfully use the ion engine. Neat stuff.
10/10.
I would like to thank the academy and…what’s that? Oh, ok.

The myths & hoaxes page from that site is interesting. Never knew meteorites could be cold when they hit the ground.

6 / 10.
And I work at NASA too.
…
Heh, I kid, I kid. I could see everyone choking on their lunch.
And, hey! We can teleport?
Very cool; thanks.
I’m not the lowest anymore. Thank you too.
Eight of them I knew for certain. Of the other two I guessed one correctly.
9/10
I didn’t know we were actually using ion propulsion systems.
I aced it too.
All those years of geeking out on astronomy magazines as a kid finally pays off 
10/10
But I guessed on the teleporter question (an educated guess, but still…), and I wasn’t 100% sure about Jupiter’s having rings.
9/10; missed # 10. I thought that was gravitationally impossible!
