Today might be the first day of autumn, but leaves aren't the only things about to fall.

The 6 ton NASA satellite is still scheduled to drop in on us sometime tonight or early tomorrow.

The bus sized Upper Atmosphere Research Satellite or UARS is slowing down in its orbit around the earth and with each go around, the 20 year old spacecraft edges closer to the surface of our planet.

At first, it looked like UARS was going to miss North America during its re-entry, but now NASA is going back on that statement and put us back on the map; meaning the satellite can hit just about anywhere.

NASA is estimating about 26 large pieces of the satellite to survive re-entry and crash to the ground. The odds of getting hit with one of these pieces are 1 out of 3,200.
