China's Long March 5B rocket crashed back to Earth on Sunday morning, landing in the Indian Ocean just west of the Maldives, the China Manned Space Emergency Office announced. Most of the debris from the rocket, which was launched in April, reportedly burned up when it re-entered the Earth's atmosphere.

The risk of the rocket causing significant damage was considered low, but experts were concerned because the 40,000-pound Long March was out of control and traveling at a high speed, making it very difficult to predict where it would land.

While it appears the worst was avoided (it's unclear if any debris landed on the Maldives, CNN notes), NASA Administrator Bill Nelson still expressed displeasure with Beijing. "Spacefaring nations must minimize the risks to people and property on Earth of re-entries of space objects and maximize transparency regarding those operations," he said. "China is failing to meet responsible standards regarding their space debris."

Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics who tracked the rocket, tweeted that regardless of the outcome, China was still "reckless." Read more at CNN and NBC News. Tim O'Donnell
