Spy Satellite Falling to Earth

AH! TEH SKY! Builds a bomb shelter. Heh. Lots of stuff falls from the sky pretty often, even man-made stuff. Seems a lot of it burns up on reentry. I'm just glad that the moon doesn't follow suit. :P On an trivia-ie note, about 2000 asteriods (my terminology may be off) hit Earth every day. The vast majority burn up, but occasionally they're large and dense enough to make impact. The very rare exception is actually noteworthy.. such as the one believed to have taken out the happy dinosaur people back those millions of fateful years ago.

The moon will follow suit, and they're now beginning to believe that mosquitos (and the diseases mosquitos transmit) may have taken out the dinosaurs. quote: ORIGINAL: CuriousLord AH! TEH SKY!

Yeah.. I remember when Skylab was falling.... I kept hoping a small piece of it would land in our yard cause it woulda been cool to have a piece of it. I'd love to be able to track it. And I wonder just WHO this particular satellite was spying on! LOL

Will it? I seem to recall that the moon is receding from earth at a rate of approximately three inches every year, which is currently attributed to tidal forces affecting the gravitional force. Heh. One of my Engineering instructors gave us extra credit if we could explain why it did that. At least, I thought he was offering extra credit until I came up with an answer.. then he told me that, no, there was none.. it was just out of interest that he posed it to the class. PS- My answer was a relativistic one, taking into account the Earth's slowing rotation as making the moon's relative rate of orbit quicker, therefore pushing it out to a further orbit. But the professor didn't seem too impressed. Meh. He wasn't a Physics professor anyhow, just Engineering (I think his Ph.D was probably in Mechanical as that was the largest major in the class).

About 10 years ago here, a lot of people heard a large sonic boom and heard an explosion. Some people saw a flash of light. The local astronomy department at one of the universities had their students out in the woods looking for an impact crater. They were all sure that it was a meteorite that all those people heard. They never did find it, but this is a densely wooded area. If it was a meteorite, it is probably still laying out there somewhere. It is fascinating stuff. We here in America have the distinct honor of having the only person to ever be hit by a meteorite. It was a woman sitting in her house in Alabama. She lived through it.
