The Long March 5B reentered the atmosphere over the Arabian Peninsula at about 10:15 p.m. EDT Saturday (0215 GMT on Sunday, May 9), according to U.S. Space Command. But some analysts have identified a watery grave for any rocket hunks that managed to survive the intense heat of re-entry. The Long March 5B launched the core module for China’s new space station on April 28. In addition, China’s first prototype space lab, Tiangong 1, which was designed to help pave the way for the new space station, had its own space-junk phase after completing its mission. “It is clear that China is failing to meet responsible standards regarding their space debris,” he added.
