A big Chinese rocket body will likely crash back to Earth tomorrow (July 30)... The 25-ton (22.5 metric tons) core stage of a Long March 5B rocket will reenter Earth's atmosphere tomorrow at 2:05 p.m. EDT (1805 GMT), plus or minus five hours... Most of the rocket body will burn up, but big chunks of it will survive the fiery passage — probably 5.5 tons to 9.9 tons(opens in new tab) (5 to 9 metric tons).. Based on the core stage's orbit, we know those hunks will come down somewhere between 41 degrees north latitude and 41 degrees south latitude....
