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.

Music: "Crest of a Wave," Lorenzo Castellarin, Universal Production Music
