wreckage of the 23-metric-ton Long March 5B hit Earth over the sea in the southwestern Philippines with the “vast majority” of the debris burning up upon reentry, according to a brief statement that was criticized by a US official.
“The People’s Republic of China did not share specific trajectory information as their Long March 5B rocket fell back to Earth,” NASA Administrator Bill Nelson said in a statement. “All spacefaring nations should follow established best practices and do their part to share this type of information in advance to allow reliable predictions of potential debris impact risk, especially for heavy-lift vehicles, like the Long March 5B, which carry a significant risk of loss of life and property,” Nelson said.
Experts had deemed the possibility of injury or infrastructure damage to be low. The rocket body had been in an elliptical orbit around Earth and was “dragged toward an uncontrolled reentry,” to Earth’s atmosphere,to the Aerospace Corp., a nonprofit corporation based in El Segundo, California, that provides technical advice for space missions and receives US funding.
Before re-entry, experts predicted that while much of the massive booster would burn up upon reentering Earth’s atmosphere, huge chunks — as much as 40% — would survive and fall to oceans or the ground. Some projections had shown a ground track that crossed parts of Mexico and Brazil, then skirted the Cape of Africa before passing over land in Southeast Asia.
