For the first time in more than a decade, five NASA Earth-observing missions will be launched into space in a single year. To celebrate this milestone, NASA is inviting people all around the world to step outside on Earth Day, April 22
, take a "selfie," and share it with the world on social media.
Designed to encourage environmental awareness and recognize the agency's ongoing work to protect our home planet, NASA's "Global Selfie" event asks people everywhere to take a picture of themselves in their local environment.
On Earth Day, 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 17 Earth science missions now in orbit help scientists piece together a detailed "global selfie" of our planet day after day. Insights from these space-based views 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. NASA Earth research also yields many down-to-earth benefits, such as improved environmental prediction and natural hazard and climate change preparedness.
