The head of NASA criticized China for the lack of data on the trajectory of the fall of launch vehicles

NASA chief Bill Nelson said that China did not share information about the fall trajectory of the Long March 5B launch vehicle. He explained that this is necessary to predict the risks of space debris falling to Earth.

“All spacefaring nations should follow established best practices and fulfill their obligation to share such information in advance to ensure reliable forecasting of potential space debris impact risks, especially when it comes to heavy launch vehicles such as the Long March 5B,” he wrote in Twitter.

China’s Manned Flight Program Administration has announced the re-entry and splashdown in the Pacific Ocean of the first stage of a two-stage heavy rocket. Part of the stage, weighing about 22 tons and 33 meters long, burned up in the atmosphere. NASA has previously criticized China for not providing data on the trajectory of missiles.

Long March 5B sent the Wentian laboratory module to the Chinese orbital station. It successfully docked on 24 July.
