In response to the question from last week about meteorites being
radioactive, Patrick informs me:
"I talked to the meteorite people here at psu. Asteroids are

*Peeking Inside Curiosity's Shell*
Mars Science Laboratory (Mars rover named Curiosity) woke up to do
some diagnostics on the way to Mars. It doesn't have a window, but it
can light up the inside of the aeroshell it's packed into and take an
out of focus image, which proves the electronics are working as
