The Sky is Falling

 "As the saying goes, what goes up must come down, and it’s time for a German satellite launched in 1990 to make the second half of that journey. ROSAT, says German Aerospace Agency DLR, is likely to fall from space between Oct. 21 and 24.
Up to 30 individual debris with a total mass of 1.7 tons could return to Earth at speeds of up to 450 kilometers per hour — likely burning from the friction of re-entry."
