Debris from a giant Chinese rocket booster is set to plummet uncontrollably to Earth and rain parts across unknown locations this weekend

At this moment, a massive Chinese rocket is in the process of crashing to Earth. Experts say the hunk of rocket junk, called the Long March 5B, will probably hit Earth this weekend.

China's rocket launched on July 24 to deliver a lab module to China's Tiangong space station, which is under construction. Researchers at the Aerospace Corporation's Center for Orbital Reentry and Debris Studies, or CORDS, said the rocket junk was descending and would begin an uncontrolled reentry into Earth's atmosphere sometime on Saturday or Sunday.

There is "a non-zero probability of the surviving debris landing in a populated area," CORDS researchers wrote on the center's website.

Using tracking data, researchers created a map that projects a potential field of locations for the space junk's reentry, but the actual reentry point is still uncertain. The blue and yellow lines indicate all the places where the rocket booster could fall.
