(Jul 29, 2022 07:32 PM)C C Wrote: A 25-ton Chinese rocket booster will crash to Earth Saturday. What's the risk? The core stage of a Chinese Long March 5B rocket is set to tumble uncontrollably back to Earth next week, in a reentry that China is tracking closely and has said poses little risk. [...] predicted to reenter Earth's atmosphere on July 30 at 7:24 p.m. ET, give or take 16 hours,
Here is is, photographed passing over Iowa (if you aren't safe in Iowa, where are you safe?) It appears to be tumbling about once a second, or about 60 rpm.

Dr. Langbroek prepared this map of 2022-085B CZ5B's orbital path for the time the Chinese say it will reenter, with the uncertainty factored in. It can complete more than six orbits in the time uncertainty range, so the thing can fall anywhere along the lines on the map. (Two of which pass overhead very close to me!)
