China has launched another Long March 5B rocket that seems liable to fall anywhere
Although the overall risk of harm to people is low—there is only a 0.5 percent chance of injury or death to a human, based on one model—these risks are nonetheless higher than accepted by most spacefaring nations, said Ted Muelhaupt, a reentry and debris expert at The Aerospace Corporation.
In an industry that can tell you things with relatively high precision, this seems odd. Why don't we know where this will fall? Is it related to how the Chinese rockets work?
