As you may have read, a certain US satellite is heading back to Earth rather faster than expected. Some people are worried that when the satellite crashes back to Earth, the hydrazine fuel cell within may cause chlorine-poisoning-like symptoms to anyone nearby. That two thirds of our planet is water and that the size of the effect isn’t much than a few acres doesn’t seem to matter. The US have decided to blow the satellite up in orbit before we get the chance to play satellite crashland lottery, in a move that many analysts see as retaliation for China shooting down its own satellite last year. At least we might get to see some pretty effects, if someone manages to capture the missile on video.
