Happy Earth Day!
As people across the globe celebrate Earth Day 2014, NASA is inviting you to take the celebration one step further by taking a #GlobalSelfie.
Five NASA missions designed to gather critical data about our home planet are launching this year. As part of the launch, the agency is asking for your help April 22.
NASA is asking us to step outside and take a picture of where you are on Earth. Then post it to social media using the hashtag #GlobalSelfie.
The agency will be monitoring five social sites: Twitter, Instagram, Facebook, Google+, and Flickr.
