Among the data published are detailed observations of 75 gamma-ray bursts from January 2021 to May 2022, which can contribute to a multiband, multi-messenger study of the cosmic phenomena for global astronomers.

NORTHEASTERN QINGHAI-TIBET PLATEAU UPLIFT

Chinese scientists used ancient tree pollen to reveal when the northeastern Qinghai-Tibet Plateau was uplifted into its current height, providing new clues to the formation of the roof of the world.

The study published in the journal Science suggested that the region rapidly uplifted to its current elevation nearly ten to eight million years ago.

AG600M FIREFIGHTING AIRCRAFT

China has put three AG600M aircraft, a full-configuration firefighting model belonging to the AG600 large amphibious aircraft family, into flight test missions.

The third AG600M firefighting aircraft prototype successfully completed its first flight test mission in Zhuhai, south China’s Guangdong Province. During the 13-minute flight, the aircraft carried out a series of planned flight tests. It performed well, and all of its systems were operating stably.
