Vanished: The Secrets Found by a Disappeared Submersible Under the Ice

An unmanned research submersible named Ran disappeared beneath Antarctica's Thwaites glacier during its second expedition, leading to a comprehensive search by researchers from the University of Gothenburg. The submersible, which had previously detailed maps of the glacier's underside, was lost under 1,500 feet of ice, marking the end of its five-year tenure. Despite the loss, the valuable data gathered by Ran during its expeditions has provided significant insights into the melting mechanisms of the glacier, with plans to replace the submersible in the future.
