Recently, several leading technologies     3     (apply) in China’s Peak Mission expedition by a total of 170 scientists who     4     (be) conducting research on water, ecology and other activities during the 2023 expedition to Mount Qomolangma as part of the second comprehensive     5     (science) expedition to the Qinghai-Tibet Plateau.

At 3 a.m on May 23rd, a group of 13 scientists     6     (form) the expedition team set off from the 8,300-meter high camp at Mount Qomolangma, known as Mount Everest in the West. After     7     8-hour climb, they reached the world’s highest automatic weather observation station at 8,830 meters above sea level around 11 a.m. The team secured fixed steel ropes, replaced batteries, installed a wind speed     8     direction sensor at the station. After     9     (approximate) one hour of work, the scientists successfully completed the maintenance and upgrade of the automatic weather station.

Currently, automated weather     10     (station) at 7,790 meters and 8,300 meters on Mount Qomolangma have completed their technical upgrades.
