The year 2014 is a big one for NASA Earth science. Five NASA missions designed to gather critical data about our home planet are launching to space this year. NASA is marking this big year for Earth science with a campaign called Earth Right Now, and as part of this campaign the agency asked for your help on Earth Day, April 22.
NASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. For Earth Day we created an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. As those pictures streamed around the world on Earth Day, the individual pictures tagged #GlobalSelfie were collected and used to create a mosaic image of Earth -- a new "Blue Marble" built bit by bit with your photos.
