NASA Earth will be launching 5 earth observing missions this year, the first such undertaking in more than a decade. To celebrate the Space Agency is inviting people all around the planet to go outside and take a picture of themselves in their local environment on Earth Day, April 22 , then share their “selfies” with the world on social media.
NASA will monitor photos posted to Twitter, Instagram, Facebook, Google+ and Flickr. Photos posted to Twitter, Instagram or Google+ using the hashtag #GlobalSelfie, or to the #GlobalSelfie Facebook event page and the #GlobalSelfie Flickr group will be used to create a crowd-sourced mosaic image of Earth – a new “Blue Marble” built bit-by-bit with #GlobalSelfie photos.
NASA’s current 17 Earth science missions now in orbit help scientists piece together a detailed "global selfie" of our planet day after day. Information gleaned from these photos are then used to "help answer some of the critical challenges facing our planet today and in the future: climate change, sea level rise, freshwater resources, and extreme weather events," as well as to help scientists predict natural hazards and climate change.
