At 1:26 am on May 15, the jumu-1 type iii floating craft, which was independently developed by China, lifted off from the base camp at an altitude of 4,300 meters and rose at an average speed of 30 meters per minute, according to the headquarters of the Expedition. It lifted over 9,000 meters at 4:26 am and reached 9,032 meters at 4:40 am, surpassing the height of 8,848.86 meters on Mount Qomolangma, setting a world record for atmospheric science observation by floating craft.

The "Peak Mission" Qomolangma expedition team, with 64 members, is the largest among the 16 expedition teams, and is composed of the Institute of Tibetan Plateau Research, The Institute of Space And Space Information Innovation and changchun Institute of Optics and Mechanics.

The floating craft has a volume of 9,060 cubic meters and a total weight of about 2.625 tons. The ground mooring vehicle weighs 90 tons. The observation instruments carried by the floating craft are mainly used to synchronously record the atmospheric composition data and water vapor transport process from the surface to an altitude of 9,000 meters. The measured data include stable isotopes of atmospheric water vapor, black carbon, dust, methane, carbon dioxide, etc., which is of great significance to the study of how westerly winds affect environmental changes over the Qinghai-Tibet Plateau.
