Well maybe not a bus...
But you are about to be hit by 6 tons of space junk, formerly known as UARS. The satellite is expected to make impact sometime this weekend. Impact? Yes impact.
Most of the 6 ton flying chunk of expired scientific junk will burn up on re-entry, but according to NASA there will be several pieces that will be large enough to reach the ground. No worries though...they have a 71% chance of hitting water (that is how much of the Earth is covered in H2O if you're wondering where the statistic came from). Other than that positive piece of news, NASA officials really cannot predict where the debris will land. There is no way to steer the satellite through re-entry, and the exact path can be affected by something as far out there as a solar storm. The debris path is expted to be about 500 miles long, and NASA says they will give more updates as we get closer to re-entry.
