A team of NASA-sponsored scientists and engineers has developed a novel approach to observing high-energy particles in the near-Earth space environment, incorporating miniaturized sensors into a compact, multi-view particle detection instrument unlike any before it. Built for NASA’s Relativistic Electron Atmospheric Loss (REAL) CubeSat mission, the innovative instrument (also calledContinue Reading

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. Scientists warn that this widespread deoxygenation is closely connected to other major planetary threats, including warming, pollution, biodiversity loss, and ocean acidification., ReadContinue Reading
