One enormous chunk of space junk is about to crash. What was once China’s first space station, a habitat designed to test docking procedures as well as perform some experiments in orbit, has run out of fuel. Like any satellite or orbiting spacecraft, without periodic altitude boosts, Tiangong will return to Earth in a fiery breakup.
The world is watching as Chinese space station Tiangong-1 hurtles toward Earth and makes a fiery reentry. Chances that space debris will hurt anybody are extremely slim, although when and where the space station’s remains will land is still unknown. aerospace.org
