The 22 ton Long March 5B rocket that placed China’s Space station in orbit is crashing someplace this weekend. It will probably be May 8-10. It will circle the world 30 times in two days. The location of where the debris will hit will not be known until moments before it is actually crashing.
Before the CZ-5B started flying there were NO “by design” uncontrolled reentries above 10 tonnes since 1990. DOS-6 (Salyut-7), STS-107 and Fobos-Grunt were all failures.
Some context for the CZ-5B core stage upcoming reentry. Here are the largest uncontrolled reentries versus time. The y axis is mass in tonnes. STS-107 Columbia is not exactly an uncontrolled reentry but is included for reference in red. The current event is in green. pic.twitter.com/S5ZB2zGqn0
