On Saturday, a Chinese booster rocket re-entered Earth without being controlled, prompting US officials to criticize Beijing for withholding information about the potentially harmful object’s descent.
US Space Command announced on Twitter that it “can confirm the People’s Republic of China (PRC) Long March 5B (CZ-5B) re-entered over the Indian Ocean at approx 10:45am MDT on 7/30.”
“We refer you to the #PRC for further details on the reentry’s technical aspects such as potential debris dispersal+ impact location,” it said.
The China Manned Space Agency later provided coordinates for an impact area in the Sulu Sea, some 35 miles (57 kilometers) off the east coast of the Philippines’ Palawan Island, in a statement uploaded to its official WeChat page.
The booster rocket, which was utilized last Sunday to launch the second of three modules China needed to finish its new Tiangong space station, was described by the agency as having had the “most of its devices ablated and destroyed during re-entry.”
The Malaysian space agency reported finding rocket wreckage that burned up during re-entry before crashing into the Sulu Sea northeast of Borneo.
“The debris of the rocket caught fire while entering the Earth’s airspace and the movement of the burning debris also crossed Malaysian airspace and could be detected in several areas including crossing the airspace around the state of Sarawak,” it said.
Bill Nelson, the administrator of NASA, criticized Beijing on Twitter for being reckless and unsafe by withholding information on the rocket’s fall.
“All spacefaring nations should follow established best practices, and do their part to share this type of information in advance,” Nelson wrote, “to allow reliable predictions of potential debris impact risk, especially for heavy-lift vehicles, like the Long March 5B, which carry a significant risk of loss of life and property.”
He added, “Doing so is critical to the responsible use of space and to ensure the safety of people here on Earth.”
One of the highlights of Beijing’s ambitious space program is the Tiangong space station, which has made China the third country to put people in orbit after the United States and Russia.
The three astronauts who had been residing in the center console since June successfully entered the new lab on Monday after the new module, launched by the Long March 5B, smoothly docked with Tiangong’s core module.
In April 2021, when China launched its first Tiangong module, there was a similar uproar regarding the potential harm that could result from an unpredictably damaging rocket reentry.
When objects enter the environment, they produce a tremendous amount of heat and friction, which can lead them to burn up and shatter. However, larger ones like the Long March-5B might not be completely destroyed.
Another Chinese rocket’s debris struck towns in the Ivory Coast in 2020, inflicting structural damage but no casualties or fatalities.
China has invested enormous sums of money in space travel and exploration in an effort to develop a program that accurately represents its status as a rising global power.
