Summary

Story summary

The robotic submarine Ran was lost beneath Antarctica's glaciers during January 2024, yet its findings advanced understanding of ice melt.
A successor, Ran II, will be delivered in winter 2026/2027 and will be built for extreme conditions.
Ran's missions showed landscapes beneath the ice and that melting is influenced by warm ocean currents for predicting sea level rise.
The new vehicle will expand Baltic Sea research and use AI for data analysis.
