I referenced the Hitchhiker’s Guide to the Galaxy in the intro to the Space quiz. Of course.

If you want to be a Fossil, where should you arrange to die? This is the quiz that tells you.

The art person got way sneaky on the quiz about Building Big – sometimes the picture gives you the right answer, and sometimes it gives you the wrong answer. Ooooohh!!

–> Note that they’re all used meteorites. What do you think the listing says? “Condition: Lightly melted on entry”?

Ok, I checked, and the actual eBay listings don’t seem to describe them as used. But still, it made me laugh.

It’s crazy, this business of living on a planet. We go around and around the sun, blundering into bits of asteroids that cross our path. We burn them with our atmosphere, melt the outsides til they’re black and shiny, and catch them with the floors of our doctors’ offices. Then they get to go around and around the sun with us, maybe even – if they’re lucky – with their own unique registration number.

Hi, rock! Welcome to Earth!

UPDATE, 1/22: An online discussion on the Post’s website about this story – hosted by two people I met on this day.

COSTAR, the space telescope equivalent of a pair of glasses, is a set of mirrors that were ground to reverse the error in the telescope’s big mirror. The astronauts on the first Hubble servicing mission also installed WFPC2, a new camera. NASA had planned to replace the original one anyway, because they knew digital camera technology would keep changing fast; the new one just had special adjustments for the messed-up mirror.

I went to the press conference this morning to check out these instruments for myself. COSTAR is shaped like a refrigerator, but much bigger, and with a set of little mirrors sticking out of one corner.

John Grunsfeld, an astronaut who’s been on three Hubble servicing missions, pulled the COSTAR out of the telescope six months ago. “It was easy,” he says. They thought it might stick, but it popped right out. He was much more excited about the glorified fuse box sitting next to COSTAR:

It’s the power control unit for the whole telescope. He pulled it out during a servicing mission in 2002. The people controlling the telescope at Goddard had to turn Hubble’s power off while he worked on it. That meant he had to work fast; otherwise, with the heaters off, the telescope might freeze. So he spent three years training on how to disconnect the unit.

You think I’m nerdily excited about these instruments, you should’ve seen him with the wrench he used to disconnect the wires. An engineer from the Goddard Space Flight Center brought it down this morning in a briefcase, and he was all happy to see it. (“This is my favorite Hubble tool!”) I don’t think the briefcase was handcuffed to the engineer’s wrist, but maybe it should’ve been. The curators were looking covetous, and there was some doubt about whether Grunsfeld would want to part with it.

Human Genome – I applaud the art person for finding pictures for this quiz.

Actually, I think I wrote some others, too…I’ll let you know when I figure out where they are.

Click here to take my quiz on the Apollo program!

Project Gemini. Did you know what NASA project came between Mercury and Apollo? Yeah, neither did I. I wasn’t born yet, you see. But now I want to take a field trip down to the Air & Space Museum to check out the capsule they’ve got on display.

Polar Science. Ah, this one was fun. I like the poles. You will do better on this quiz if you have seen Encounters at the End of the World, the Werner Herzog documentary about Antarctica. It’s a great movie, so you should see it even if you don’t organize your life around doing better on my quizzes.
