Today, the "Peak Mission" Everest Expedition will open the "Peak Moment". The 12 expedition team members will work together with the Forward Command of Everest Base Camp at the summit to complete the most critical and challenging summit scientific expedition comprehensive task. These include the installation of the world's highest automatic weather station at an altitude of 8800 meters; the first time at the top of the earth to use high-precision radar to measure the thickness of ice and snow, collect ice and snow samples, and experiments on the human body's extremely high altitude adaptation mechanism.
The Tibetan Plateau is the roof of the world, the water tower of Asia, and the third pole of the earth. Since the 1950s, the mainland has carried out more than 6 Scientific Expeditions to Mount Everest, including the first large-scale comprehensive scientific expedition to the Tibetan Plateau in the 1970s.
The "Peak Mission" Everest Scientific Expedition was fully launched on April 28 this year, with a total of 5 scientific expedition teams and 16 scientific expedition teams with more than 270 scientific expedition team members participating, which is the comprehensive scientific expedition with the widest subject coverage, the largest number of participants in the scientific expedition team, and the most advanced instruments and equipment since the second Qinghai-Tibet Scientific Expedition in 2017, and is a feat of human beings to carry out extremely high altitude comprehensive scientific investigation and research in the Everest region.
At 3 o'clock in the morning today, due to the frostbite on the hands of 1 expedition climber, he remained at an altitude of 8300 meters, and the remaining 12 expedition climbers had set off from the assault camp at an altitude of 8300 meters, and were expected to arrive at the 8800 meters to erect a weather station at about 9 o'clock to carry out a series of scientific expedition tasks.
What are the tasks of the Summit Expedition
After these 12 scientific expedition climbers reach the summit, what scientific expedition tasks do they have?
On the morning of May 4, the 12 expedition team members will be divided into three groups to complete three tasks at the same time after reaching the summit. These include the installation of the world's highest altitude weather station at 8800 meters, the measurement of ice and snow thickness with high-precision radar, and the experiment of the human body's extremely high altitude adaptation mechanism. The summit is imminent, and the scientific expedition team at the base camp is also very concerned, interacting through the intercom.
May 3, 2022 at noon 5200m base camp and the expedition climbers dialogue:
Tsering Samdrup, rear commander of the expedition summit team: Za team, you expect to reach 8300 meters at what time.
"Peak Mission" Everest Expedition To the Summit Offic Expedition Deputy Leader Zaping: We may be six or seven o'clock in the afternoon to 8300 meters, and now we have to add something at 7790 meters. Then head up again.
Tsering Samdrup, rear commander of the expedition summit team: Okay, hard. Pay attention to safety, we must do a good job of keeping warm measures, and the degree of protection must be done well. Wait for you to reach the news of 8300 meters.
On the way to start the scientific expedition to the top, the scientific expedition climbing personnel inspected and debugged the automatic weather stations that had been erected at an altitude of 7028 meters, 7790 meters and 8300 meters along the way.
Zhao Huabiao, project researcher of the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences: At present, one of the difficulties is the installation time, because the time to stay at high altitudes cannot be too long, because they are the amount of oxygen used, and the physical strength is to let them install quickly. The second is whether you can send the data back as soon as it is installed, because if there is a problem, it is not easy to solve it.
Detecting the thickness of ice and snow at the summit is also the focus and difficulty of this expedition. The equipment carried by the climbers is mainly high-precision ground-penetrating radar. In addition to measuring the summit, these radars also measure the entire Everest Rongbu Glacier.
Yang Wei, project researcher at the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences: High-precision lidar scans elevation changes to see the changes in its glaciers
At an altitude of 5800 meters, the Ice Tallinn Road to the East Rongbuk Glacier
The "Peak Mission" Everest Expedition is the landmark scientific expedition of the second Qinghai-Tibet scientific expedition, in which the members of the expedition team climb to an altitude of 5800 meters to 6700 meters above sea level to drill ice cores, measure the thickness of ice radar, collect snow samples and other scientific expeditions. Therefore, the East Rongbu Glacier Ice Tallinn Road from an altitude of 5800 meters upwards is a road that the extremely high altitude scientific expedition team must go through together to see the experience of the reporters of the main station.
Tang Wei: My current location is the transition camp at an altitude of 5800 meters, today I will go to the forward camp at an altitude of 6500 meters, this road happens to be the most densely distributed place in the Ice Tallinn of the East Rongbu Glacier, so today we also have the honor to invite Professor Li Zhen of the Ice Core Group of the Qinghai-Tibet Plateau Research Institute to walk with us all the way, and he will introduce us to the various forms of ice tallinn on the road, the reasons for its formation and other knowledge.
As soon as we left the 5,800-meter camp, it was a very steep uphill climb, so we changed into light gear and struggled to climb up the valley. After half an hour, our way forward became very clear, that is, along the moraine in the middle of the two branches of the East Rongbu Glacier. From an aerial perspective, the two branches of the East Rongbu Glacier take on a huge "X" shape, and the ice tallinn glows a faint blue color, which is spectacular in the sunlight.
Tang Wei: Now our altitude has reached about 6,000 meters above sea level, and every step we take is very cramped, and now we are the most spectacular place in the ice Tallinn of the East Rongbu Glacier.
Reporter: I see that Ice Tallinn has great individual differences in each of them, why is that?
Li Zhen, professor of the ice core group of the Qinghai-Tibet Plateau Research Institute: Glacier is the meaning of river, our glacier is also a river, but it is ice, in the flow, the glacier is also flowing, that is, in the process of flow, in a certain period in history, the temperature suddenly rises, the flow speed below is fast, the ice is disconnected, pulled apart, and a cross-section is formed.
As the altitude rises, the temperature gradually drops, and the wonders of ice Tallinn are more and more presented, you see this ice tallinn resembles a general with a bull's head, his horns pointing to the sky, and this ice Tallinn looks like a throne, waiting for the frozen ice lake...
