It looks like Chicken Little might have been right, because just a month after that huge NASA satellite fell back to Earth, it's time to keep an eye out for another satellite that's about to come crashing back home.

The German Roentgen Satellite or ROSAT is expected to re-enter the atmosphere this weekend, but the European Space Agency seems to be pretty clueless about where it might hit. They put the chances of someone being struck by debris at about 1 in 2,000, pretty remote, but worryingly higher than the 1 in 3,200 chance given for the NASA satellite. If you want to know when to duck, you can follow ROSAT's path here.

The NASA satellite was described as being about the size of a bus. ROSAT is only minivan sized, but a lot of its weight is from special heat resistant mirrors that could hit Earth in one piece. One of those will definitely leave a mark if it hits you.
