Debris from Chinese rocket expected to crash to Earth in uncontrolled re-entry
"Regarding the Long March 5 launched several days ago, there is no known plan, which equally has been the case for previous launches of this vehicle," UK-based space-tracking expert Sean Goldborough, director of Northern Space and Security , told BBC News.
Designing objects to disintegrate upon atmospheric re-entry is becoming a priority for satellite operators. It's done partly by using materials which have low-melting point temperatures, such as aluminium. Despite this, other space agencies have been designing their rockets to disintegrate into smaller pieces during re-entry ever since large chunks of the Nasa space station Skylab fell from orbit and landed in Australia in 1979.
