HELSINKI – Rocket debris, which is expected to hit the moon in March, does not come from the 2014 Chang’e-5 T1 mission, according to the Chinese Foreign Ministry.
“According to Chinese monitoring, the upper stage of the rocket associated with the Chang’e-5 T1 mission entered the Earth’s atmosphere and burned completely,” said Foreign Ministry spokesman Wang Wenbin. said February 21.
Space tracking data from the 18th Space Forces Space Management Squadron suggests that 2014-065B re-entered the atmosphere in October 2015, a year after launch, clearly supporting China’s demand.
The claim adds more mystery to the event, which has attracted widespread attention since it was first reported that the object is affecting the moon.
Astronomer Bill Gray reported On January 21, the object, designated WE0913A, was on a trajectory that would to face with the month of March 4th. Gray originally linked the wreckage to the launch of the Falcon 9 Deep Space Observatory (DSCOVR) in February 2015.
Gray revised WE0913A identification on 12 February however, this suggests that it is better suited for the upper stage of the Long March 3C missile, with which the Chinese Chang’e-5 T1 was launched in 2014, an object listed in the international designation 2014-065B. “In a sense, this remains ‘indirect’ evidence,” Gray wrote, adding a caveat.
The Washington Post later said in a statement by NASA’s Jet Propulsion Laboratory Center for Near-Earth Objects, which said it was probably Chinese Chang’e 5-T1 launch vehicle, launched in 2014. Independent spectral analysis University of Arizona students also claimed to have confirmed the identity of the facility as most likely belonging to a Chinese mission.
The new development, if confirmed, highlights the problem of tracking objects in deep space. In his reports on the facility, Gray notes that tracking debris in deep space was not “this serious problem,” explaining that tracking U.S. space forces focused on lower orbits.
Radar, which is mostly used, can track objects about 10 centimeters in size in lower orbits, but telescopes are needed to track even large objects that are farther from Earth.
The event also emphasizes the importance of sustainability in the future of space operations. Both the United States and a number of partners, China and Russia, are planning Artemis and the International Research Station of the Moon (ILRS) programs to establish a long-term presence on the moon.
Chang’e-5 T1 was a test mission for a more ambitious mission to return samples from the moon. He successfully tested a high-speed spacecraft to “miss the return” after returning from the moon, confirming that the return capsule could safely deliver moonstones to Earth.
The upper stage of the Long March 3C missile for the mission also carried out the Manfred Memorial mission in Luxembourg.
The full Chang’e-5 mission was launched in November 2020, collecting 1.7 kilograms of fresh lunar samples from the Moon and delivery them to Earth in December 2020.
The top rung of this mission, launched by “Long March 5”, re-entered over the Pacific a week after launch.
“China’s aerospace efforts are always in line with international law,” Wang said Monday in response to a question from the Associated Press about the moon’s future impact.
“We are committed to seriously protecting the long-term sustainability of space activities and are ready for extensive exchanges and cooperation with all parties.”
