In two days (on Thursday, Feb. 18th, 2021), NASA’s Perseverance rover will land on Mars. As the latest robotic mission in the Mars Exploration Program (MEP), Perseverance will follow in the footsteps of its sister mission, Curiosity. Just in time for its arrival, research conducted at the Southwest Research Institute (SwRI) has shown that Mars’ surface was shaped by […]

Artist’s depiction of the Moon in the magnetosphere, with “Earth wind” made up of flowing oxygen ions (gray) and hydrogen ions (bright blue), which can react with the lunar surface to create water. The Moon spends >75% of its orbit in the solar wind (yellow), which is blocked by the […]

Among the report’s case studies: Africa’s Kariba Dam, the world’s largest man-made reservoir, impounding 181 km³ of water. Almost $300 million was loaned in 2014 to repair the dam, with completion expected by 2023. The report says “Dams like Kariba will likely continue to operate much longer with recurring investments […]

Stanford researcher Ryan Searcy collects water samples from a tide pool at the Fitzgerald Marine Reserve, in Moss Beach, California. Credit: Meghan Shea Using water samples and environmental data gathered over 48 hours or less, Stanford engineers develop a new predictive technique for forecasting coastal water quality, a critical step […]

A dryland ecosystem in Northern California shows decreasing soil moisture but little changes in surface water availability. Credit: Columbia Engineering New Columbia Engineering study — first to investigate the long-term effect of soil moisture-atmosphere feedbacks in drylands — finds that soil moisture exerts a negative feedback on surface water availability […]

This 3D model of a polymer desalination membrane shows water flow — the silver channels, moving from top to bottom — avoiding dense spots in the membrane and slowing flow.

Water on Mars, in the form of brines, may not be as widespread as previously thought, […]

A solution to the growing clean drinking water availability problem is direct solar steam generation technology, which can remove harmful soluble pollutants from water. Credit: Lei Miao from SIT Scientists review some of the research behind a technology that could cauterize a growing global drinking water crisis. A nascent but […]
