10 Years of Aqua Satellite’s Incredible Images of Earth From Space
One of the stars of NASA's fleet of satellites is Aqua, named for its ability to measure water vapor in the atmosphere, water in the oceans, as well as ice and snow. As of May, Aqua's six instruments had been functioning perfectly for 10 years, gathering 29 million gigabytes of data in that time. This collection of some of Aqua's most beautiful images, including the one above of Mt. Etna erupting, was our second most popular gallery of the year.
