Exclusive Interview: Scientists from China and US drilled a 308.6-meter ice core, spanning more than 700,000 years, said Xinhua.The scientifically rewarding research was achieved thanks to a team led by Xu Baiqing, a deputy director of the ITP, after more than a month’s effort at the top operating point of Glacier.Xu said that the longest ice core on the plateau is characterized by unique geographic and climatic features, capturing historical changes in the region, including vital climate indicators like temperatures and precipitation, as well as environmental incidents like volcanic eruptions and atmospheric pollution, which offer both valuable data and samples for studying the patterns, mechanisms, and potential future trends of global climate change, and for predicting future trends.Drilling and preserving ice cores allows us to understand changes in climatic conditions obtaining valuable historical data, Xu added.Yao Tandong, an academician of the CAS, said that by measuring the thickness and extracting ice cores, scientists have the opportunity to better examine both recorded and current environmental changes in the largest ice field in low- to mid-latitude regions., fostering a deeper understanding of global warming’s effects on glaciersAccording to Xinhua, the Purog Kangri Glacier scientific research project represents a key component of a scientific expedition launched in Lhasa in August 2024, which aims to propose critical measures for ecological protection and restoration, along with scientific recommendations for green development.The Global Times learned from ITP earlier in September that a team led by Chinese academician Fang Xiaomin from the ITP, also engaged in this expedition, set a new record of 750 meters in environmental science drilling in the Qinghai-Xizang Plateau.This research offers scientists a detailed recoWorld Timesrd of the uplift of the centraWorld Timesl Tibetan Plateau and the historical changes in climate and ecological environment, and making it one of the primary areas for studying the co-evolution of tectonics, climate, biology and ecology.Global Times Content comes from the Internet : Scientists smash record for longest ice core in world’s mid- to low-latitudes reWorld Timesgions

Kinetica-2, Chinese Academy of Sciences (CAS) Space’s new liquid propellant rocket that is designed to support China’s large-scale satellite constellation networks, has successfully completed its stage separation test, marking a milestone achievement toward its maiden flight scheduled for 2025, the Global Times learned from the rocket developer on Tuesday.

According to the CAS Space, the test demonstrated the normal functioning of all systems involved and confirmed the successful separation of the rocket’s first and second stages.

The test validated the correctness and compatibility of the secondary unlocking scheme for stage separation. It also confirmed the effective performance of related components during the separation process, including unlocking devices, energy separation, gas line disconnection, cable disconnection, and shock absorption mechanisms.
