Over 14 years of spaceborne observations, the Gravity Recovery and Climate Experiment (GRACE) mission tracked the movement of freshwater around the world. Wet areas got wetter and dry areas drier, caused by factors like human activity, climate change and natural weather cycles. Scientists combined GRACE data with measurements from other satellites, like Landsat and the Global Precipitation Measurement (GPM) mission, to determine the causes of some of these changes. For example, agricultural acti

NASA’s Carruthers Geocorona Observatory has begun its 2-year science mission. 🛰️ From ~1 million miles away, the spacecraft is capturing the UV glow from Earth’s outer atmosphere. The data will help us understand how hydrogen (and water) from Earth escape to space. 🌎💦🌌 More: go.nasa.gov/4rJjg5n | NASA Solar System Exploration
