NASA researchers are presenting new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union this week in San Francisco. With about 24,000 attendees, the meeting is the largest gathering of Earth and space scientists in the world. The full range of NASA’s innovative science and technology is on display. Key findings include new evidence from NASA’s Curiosity rover of how ancient lakes and wet underground environments on Mars changed billions of years ago affecting their favorability for microbial life. A new Earth-observing satellite data set and imagery was released providing a near-real-time view of every large glacier and ice sheet on Earth. The meeting continues through Dec. 16.
