Debris from a 25-ton Chinese Long March 5B rocket crashed to earth on Saturday afternoon over the Indian Ocean. This is not the first time the Chinese have failed to control the reentry of space debris, and it likely won’t be the last. One thing is certain: If this “space junk” had fallen over a populated area, it would have had deadly consequences.
U.S. Space Command confirmed this development on Twitter and referred readers to the People’s Republic of China for further information about “potential debris dispersal and impact location,” details with which the government appears to have little concern.
#USSPACECOM can confirm the People’s Republic of China (PRC) Long March 5B (CZ-5B) re-entered over the Indian Ocean at approx 10:45 am MDT on 7/30. We refer you to the #PRC for further details on the reentry’s technical aspects such as potential debris dispersal+ impact location.

Mike Wall of Space.com reported the rocket was launched on July 24. Its mission was to transport a new module to China’s Tiangong space station, which is currently under construction. Wall explained that “unlike the core stages of most rockets, which are steered to a safe disposal shortly after launch or land softly for future reuse, the Long March 5B reached orbit along with its payload. And it stayed up — as a big, fast-moving piece of space junk — until atmospheric drag brought it down in an unpredictable and uncontrolled fashion.”
Wall noted the uncontrolled reentry of the Long March 5B was not an accident. Instead, this “end-of-life scenario is built into” its design. Because the “rocket doesn’t burn up completely upon reentry,” needless to say, critics find this “disposal strategy” to be reckless.
Although it’s unknown how much of the 25-ton rocket survived (did not burn up), Wall reported that experts at The Aerospace Corporation’s Center for Orbital Reentry and Debris Studies put the figure at somewhere between 5 and 10 tons.

Following the rocket’s reentry, NASA Administrator Bill Nelson put out a critical statement that read, “The People’s Republic of China (PRC) did not share specific trajectory information as their Long March 5B rocket fell back to Earth.
“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.
