When searching for signs of life on other planets, scientists say caves are a crucial place to look. But how can a team on Earth effectively explore intricate, dark, unfamiliar landscapes on another world?
NASA and Boston Dynamics have found an answer: Fully autonomous robots. Caves are one of the most likely places to find signs of both current and past life on other planets because they are capable of protecting life from cosmic rays and extreme temperature fluctuations around our solar system. A NASA project called BRAILLE is now working on exploring Mars-like caves that already exist on Earth in order to hone key technologies for future missions.More Related News
