新素材·南极考察 ①China’s polar research icebreaker Xuelong finished the main missions in the Amundsen Sea and Ross Sea in February, 2026, marking a key milestone in the 42nd Antarctic Expedition(考察). On November 1, 2025, China’s 42nd Antarctic Expedition team set sail from Shanghai. They have to carry out a seven-month mission, supported by the country’s two icebreakers, Xuelong and Xuelong 2.
②Among its many tasks, the team drilled and collected samples(样本) from under an ice sheet(冰盖) more than 3,000 metres thick for scientific research on Antarctica. They also tested new machines, such as the Snow Leopard 6×6 wheeled vehicle, which was designed and built in China.
③For over 40 years, China has been exploring Antarctica and achieving plenty of firsts. Its very first expedition team set off in November 1984, also from Shanghai. Three months later, China’s first Antarctic research base, the Great Wall Station, was built. In 1994, China’s first icebreaker, Xuelong, entered service. Since then, it has travelled to Antarctica over 30 times!
④In 2005, the 21st expedition team climbed all the way to Dome A, the highest point of the Antarctic ice sheet. It was the first time in history anyone had reached it from the ground. The list of big moments like these goes on and on.
⑤You might ask why we keep going back to Antarctica. Well, it’s the key to understanding how our planet works—especially the climate and environment. There is also a record showing what our planet was like over the past million years.
⑥“Continuously improving our ability to understand, protect, and use Antarctica is a requirement for China to build itself into a strong oceanic nation,” said Long Wei, deputy director of the Chinese Arctic and Antarctic Administration.
⑦Antarctica is like the Earth’s history book. It’s also where our planet’s past and future meet. As the 42nd expedition has set sail, it carries with it a deeper sense of responsibility for the Earth’s future.
