Inspired by Mars landing, scientists to use Perseverance rover's navigation system to map Oceans on Earth We know more about the Moon than we know about the oceans on Earth. advertisement UPDATED: May 20, 2021 12:54 IST Orpheus can work untethered almost anywhere in the ocean, including the most extreme depths. (Photo: JPL) When the Perseverance rover hurtled down Mars's thin atmosphere towards the Jazero crater, a unique navigation technology helped guide it to a location that was most favourable for its survival during touchdown. This same technology is now going to be used to guide an autonomous vehicle to identify new features in the Atlantic Ocean.
