China has introduced a revolutionary new ocean drilling vessel called the ‘Mengxiang’, designed to penetrate the Earth’s crust and reach the mantle for the first time in human history. If successful, the Mengxiang’s planned drilling to breach the Mohorovicic discontinuity (Moho) over 7,000 metres beneath the ocean floor would open the door to unprecedented scientific exploration and discovery within the planet. Crafted through collaboration between China’s Geological Survey and over 150 institutes, the Mengxiang is an enormous, specially-equipped ship capable of withstanding extreme conditions.
