The year 2014 is a big one for NASA Earth Science. Five missions designed to gather critical data about our home planet are launching to space. 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 is marking this big year for Earth Science with a campaign called Earth Right Now, and as part of this campaign the agency is asking for our help this Earth Day, April 22.
Designed to encourage environmental awareness and recognize the agency’s ongoing work to protect our home planet, NASA is inviting people all around the world to step outside on this Earth Day, take a “selfie" with the hashtag #GlobalSelfie and share it with the world on social media.
On Earth Day, NASA will monitor posts to Twitter, Instagram, Facebook, Google+ and Flickr using the hashtag #GlobalSelfie, and on May they will release a crowd-source mosaic image of Earth - a new "Blue Marble"- built bit-by-bit with our photos.
So, on April 22, step outside and join the celebration!
