An earlier report that debris from the recently deorbited UARS satellite had landed in Canada
may have been premature. Apparently, the picture of when (and therefore where) the satellite deorbited is back to being clear as mud
. Most likely, says NASA, the debris will never be found, but is thought to have landed in the Pacific Ocean. If you're an optimist interested in finding your very own piece of space debris, though, you might be interested in this map based on various re-entry scenarios
(hat tip to Robert Woodcock); in the U.S., the Northwest is your best bet.
