A little over a decade from now, NASA plans to send astronauts to Mars for the first time. This mission will build on decades of robotic exploration, collect samples from the surface, and return them to Earth for analysis. Given the immense distance involved, any operations on the Martian surface will need to be as self-sufficient as possible, which means sourcing whatever they can locally.
This includes using the local water to create oxygen gas, drinking water, and rocket fuel, which represents a challenge considering that any liquid water is likely to be briny. Luckily, a team of researchers from the McKelvey School of Engineering at Washington University at St. Louis (WUSTL) has created a new type of electrolysis system that can convert briny water into usable products while also being compact and lightweight.
