As humankind imagines living off-planet — on the moon, Mars and beyond — the question of how to sustain life revolves around the physical necessities of oxygen, food and water. We know there is water on the moon, but how do we find it? Researchers from UC San Diego may help bring science fiction to reality by providing a divining rod to guide future space missions. Their work appears in a special issue of Proceedings of the National Academy of Sciences called “Water on the Moon and Mars,” which features Artemis I on its cover.

An interdisciplinary team of researchers from Nanyang Technological University, Singapore (NTU Singapore), and Delft University of Technology (TU Delft), The Netherlands, has projected that if the rate of global CO2 emissions continues to increase and reaches a high emission scenario, sea levels would as a result very likely rise between 0.5 and 1.9 metres by 2100. The high end of this projection’s range is 90 centimetres higher than the latest United Nations’ global projection of 0.6 to 1.0 metres.
