Chinese rocket falls to Earth, NASA says Beijing did not share information

Social media users in Malaysia posted video of what appeared to be rocket debris

A Chinese rocket fell back to Earth on Saturday over the Indian Ocean but NASA said Beijing had not shared the "specific trajectory information" needed to know where possible debris might fall.

U.S. Space Command said the Long March 5B said the rocket re-entered over the Indian Ocean at approximately 12:45 p.m. EDT Saturday (1645 GMT), but referred questions about "reentry’s technical aspects such as potential debris dispersal impact location" to China.

"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," NASA Administrator Bill Nelson said. "Doing so is critical to the responsible use of space and to ensure the safety of people here on Earth."

Aerospace Corp, a government-funded nonprofit research centre near Los Angeles, said it was reckless to allow the rocket's entire main-core stage — which weighs 22.5 tons (about 48,500 lb) — to return to Earth in an uncontrolled reentry.

Earlier this week, analysts said the rocket body would disintegrate as it plunged through the atmosphere but is large enough that numerous chunks will likely survive a fiery re-entry to rain debris over an area some 2,000 km (1,240 miles) long by about 70 km (44 miles) wide.
