Beneath one of Antarctica's most vulnerable ice shelves, a machine traveled where no human can go and returned with a portrait of the unknown — teardrop-shaped formations and ice dunes carved by forces our best models cannot yet explain. The autonomous vehicle Ran mapped the underside of the Dotson ice shelf in 2022, completing a 1,000-kilometer survey that revealed a subglacial world far more complex and dynamic than science had imagined. What it found does not merely add detail to existing knowledge — it demands that glaciologists rebuild their understanding of how ice shelves melt, and with
