"description": "This visualization shows sea surface salinity (SSS) data of the oceans from August 2011 through July 2014. The data set used is from the Aquarius satellite. Aquarius is a collaboration between NASA and the Space Agency of Argentina to measure global sea surface salinity (the amount of dissolved salts in water). Measuring salinity can help us better understand the water cycle and can also lead to improved climate models.
This visualization was created in part to support Earth Day 2020 media releases.",

"description": "It’s been five decades since Apollo 8 astronaut William Anders photographed Earth peaking over the Moon’s horizon. The iconic image, dubbed Earthrise, inspired a new appreciation of the fragility of our place in the universe. Two years later, Earth Day was born to honor our home planet. As the world prepares to commemorate the 50th anniversary of Earth Day, NASA reflects on how the continued growth of its fleet of Earth-observing satellites has sharpened our view of the planet’s climate, atmosphere, land, polar regions and oceans. || ",
