As more space junk falls to Earth, will China clean up its act?

Parts of a 23-tonne piece of rocket will come crashing down - somewhere - in the next few days

In the next few days, a 23-tonne piece of rocket will plummet to Earth at about 15,000 miles an hour. Much of it may burn up on re-entry, but a significant amount will not.

It could land as one piece but more probably as many, scattered over an area up to several hundred miles across. Scientists have narrowed down the likely impact zone to within the latitudes of 41 degrees north and 41 degrees south, a region covering much of the US and South America, Africa, the Middle East, most of Asia, and all of Australia except the island of Tasmania.
