我国科考队圆满完成北极载人深潜任务 “奋斗者”号完成43次下潜，并与“蛟龙”号水下协同作业

Core Viewpoint - The Chinese scientific research team successfully completed a manned deep-sea diving mission in the Arctic, utilizing the domestically designed and built ice-capable mother ship "Exploration No. 3" and the manned submersible "Fighter" [1][2]. Group 1 - The mission lasted 56 days, starting from July 22, with the "Fighter" completing 43 dives in the Arctic [1]. - The "Dragon" manned submersible achieved China's first manned deep-sea dive in the Arctic ice zone, collaborating underwater with the "Fighter" to innovate a dual submersible operation model [1][2]. - The "Fighter" reached a maximum diving depth of 5,277 meters during the mission, conducting the first manned deep-sea scientific research in the Arctic's Gakkel Ridge [1][2]. Group 2 - The mission validated the operational capabilities and application value of the "Fighter" and "Exploration No. 3" in polar ice regions, achieving significant technological breakthroughs in extreme environment operations [2]. - The research team established operational protocols for the "Fighter" in extreme polar conditions, creating a new mobile ice-diving model for ship-submersible collaboration [2]. - The mission allowed for the collection of valuable water, sediment, rock, and biological samples, providing crucial observational data for studying rapid climate change in the Arctic and the evolution and adaptation mechanisms of polar life [2].
