Mysterious 'Space Ball' Crashes in Namibia (http://www.foxnews.com/scitech/2011/12/23/mysterious-space-ball-crashes-in-namibia/)

That's an Imperial probe droid.

It's a good bet the Empire knows we're here.

Start the evacuation.

Thats what a typical fuel tank looks like on a satellite. They use Hydrazine for fuel, pretty nasty stuff.

Maybe it's a meteor, like this one I found back a few years ago.

That's what it looked like to me, too, a propellant tank. I think the explanations people come up with are great.

In case anyone wonders, they are made to handle about 600 psi through pretty crazy vibe and shock. Made usually of 6/4 titanium, probably about 0.125" thick. They're sometimes insulated with graphite fabric, which would burn off, although the tank itself is fairly robust. They reckon maybe a couple of dozen from satellites have come home to Earth over the years, although most probably are destroyed. Maybe this one had some hydrazine left in it that absorbed the heat and didn't burn up.

Here's one probably very similar on the upper stage of an Ariane V. These are recovered or end up at the bottom of the ocean.

Another on the ESA Galileo bus. This one is much bigger because it has to last for years.
