The Earth’s moon contains ice, but scientists don’t know much about where the water came from. As the moon formed, water could have come from Earth’s volcanoes in the form of gas. It could have been brought there by comets and meteorites. Or, it may have traveled to the lunar surface via solar wind that interacted with minerals on the moon to create water.
Researchers at Washington University in St. Louis are teaming up to find some answers. The team has been chosen as one of NASA’s eight new Solar System Exploration Research Virtual Institutes. They are part of a five-year cooperative agreement valued at more than $7 million.
