What Should You Do If You Find a Piece of China's Crashed Space Station?

China's defunct Tiangong-1 space station is careening through low-Earth orbit right now, and is expected to reenter Earth's atmosphere sometime between March 30and April 2. Most of the 9-ton(8,500 kilograms) space station will probably burn to bits in the atmosphere — but a few thousand chunks of hot, mangled debris are still likely to survive the trip and land on our planet's surface.
Your odds of being conked on the head by any of this debris are low — about one in 292 trillion, or roughly a million times less likely than hitting the Powerball jackpot. Right now, the potential impact site of the space station covers about one-third of the planet, and a huge majority of that zone is water.
