China is very prudent on this point and has not published any indication of the hourly ability of the launcher to return to Earth’s atmosphere, where it will break down completely or partially.

For the Russian space agency Roscosmos, the entry can be made at 7:30 pm on Saturday (EDT) at the level of southern Indonesia. However, the U.S. Department of Defense is at 9 pm with a margin of nine hours error on both sides of this estimate

The window should gradually thin out in hours.

After a lengthy embarrassing silence from Chinese space and diplomatic officials, Beijing finally responded on Friday.
