Sun-Stripped Mars Can Help NASA's MAVEN Provide Exoplanet Insights

Early Mars once boasted an atmosphere and even oceans, but as the active sun evolved, it began to strip the Red Planet of its air, a process that has also been spotted in action outside the solar system. NASA's MAVEN mission, currently orbiting Mars, may help scientists to understand the atmosphere of other rocky worlds undergoing that process. "We're at the brink of starting to understand the habitability of terrestrial planets," said Shannon Curry, a research scientist at the University of Cal
