Ascending the sky, entering the earth, drilling into the sea, and mountaineering are the "probes" of Chinese scientific exploration. In recent years, they have repeatedly touched the unknown time, space, and fields of humanity. At around 12:30 on the 23rd, 13 Chinese scientific research team members successfully climbed Mount Everest. On the occasion of the 70th anniversary of humanity's first ascent to Mount Everest, China's scientific research on Mount Everest has once again surpassed an altitude of over 8000 meters after 2022. The towering Mount Everest once again witnesses history! At 3am on the same day, the expedition team set off from the assault camp at an altitude of 8300 meters and after several hours of climbing, finally arrived at the world's highest automatic meteorological observation station at an altitude of 8830 meters. After about an hour of intense work, the upgrade of the meteorological station components has been completed, including fixing the steel wire rope, replacing the battery, and installing the wind speed and direction sensor. Subsequently, they climbed to the peak of 8848.86 meters and successfully collected snow and ice samples using tools. In the command tent of Mount Everest's headquarters at an altitude of 5200 meters, scientists and staff applaud warmly for each task completed by the expedition team. The comprehensive investigation and research of the Mount Everest region in 2023 is part of the second comprehensive scientific investigation and research of the Qinghai Tibet Plateau. Since the end of April, 170 members from 5 scientific research teams and 13 scientific research teams have continued to focus on water, ecology, and human activities, fighting against high temperatures, wind and snow, exploring nature in the Everest region, questioning science, and climbing bravely. Climbing the Peak Again: Unravel the "New Treasure" of Mount Everest for scientific research. The Qinghai Tibet Plateau is known as the "Natural Laboratory" by the scientific community, and Mount Everest and its surrounding areas are one of the precious gems that urgently need to be scientifically recognized. An important task for this year's Everest scientific examination is to maintain and upgrade the technology of eight meteorological stations that have been installed at altitudes ranging from 5200 meters to 8830 meters. According to Zhao Huabiao, the head of the High Altitude Meteorological Gradient Observation Group for the Second Qinghai Tibet Scientific Examination, the maintenance and upgrading focus has been on battery life issues in extreme environments. Precipitation observations have been added at meteorological stations below 6500 meters above sea level to obtain more comprehensive gradient meteorological observation data, providing basic data for studying the changes in meteorological elements, glaciers, and snow cover at extremely high altitudes. Another breakthrough in this year's scientific research is the rediscovery of Himalayan ichthyosaur fossils after nearly 60 years. The Himalayan ichthyosaurus was discovered and named during scientific research on the Qinghai Tibet Plateau in the 1960s. The discovery of ichthyosaur fossils direct proof that Mount Everest was once a vast ocean. During this scientific expedition, the Qinghai Tibet scientific expedition team of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences made a major discovery: in at least three strata of the Triassic Qulonggongba Formation in the south of Gangga Town, Dingri County, certain vertebrate skeleton fossils were found. Judging from the skeletal structure, it is the fossil of the Himalayan ichthyosaur, which has been nearly 60 years since the last discovery of the Triassic Himalayan ichthyosaur. Wang Wei, an associate researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, said that the newly discovered fossils are quite complete and will provide more and more accurate scientific information for further research on this prehistoric sea monster in the Everest region. As an important discovery, researchers will prioritize the study of ichthyosaurus fossils
