Satellites also helped bring us discovery – like the “mega-canyon,” longer than the Grand Canyon, found under a mile of Greenland ice. Meanwhile, far from the world’s ice sheets, scientists used a new technique to measure the fluorescence of plants. The visualized result shows a glowing world that is both awe-inspiring and instructive.
The satellite view of Earth allows for everything from the terrifying to the peaceful. Satellites gave us imagery of typhoon Usagi rapidly intensifying and they gave us humbling images of a storm that spawned tornadoes in Oklahoma. Satellites also showed us how the seasons change, and how the world looks from above, on the International Space Station, as the Earth spins and night turns to day.
NASA works to better understand and protect our home planet. Our data and research helps improve environmental prediction and prepare for natural hazards and climate change. In 2014, five NASA missions are launching to space – the most active year for NASA Earth science in more than a decade.
