NASA invites you â€” and everyone else on the planet â€” to take part in a worldwide celebration of Earth Day this year with the agencyâ€™s #GlobalSelfie event.
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 is asking for your help this Earth Day, April 22.
While NASA satellites constantly look at Earth from space, on Earth Day NASA is asking you to step outside and take a picture of yourself wherever you are on Earth. Then post it to social media using the hashtag #GlobalSelfie.
Whatâ€™s a #GlobalSelfie?
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 NASA is trying to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. Once those pictures stream around the world on Earth Day, the individual pictures tagged #GlobalSelfie will be used to create a mosaic image of Earth â€” a new â€œBlue Marbleâ€ built bit by bit with your photos.
Need an idea of what kind of picture to take? Get outside and show NASA mountains, parks, the sky, rivers, lakes â€” wherever you are, thereâ€™s your picture. Tell NASA where you are in a sign, words written in the sand, spelled out with rocks â€” or by using the printable signs they have created that are available at the bottom of this linked page.
The Earth mosaic image itself and a video using the images will be put together and released in May.
How do I take part?
NASA will be monitoring photos posted to five social media sites: Twitter, Instagram, Facebook, Google+ and Flickr.
Post your photo to Twitter, Instagram or Google+ using the hashtag #GlobalSelfie, or post it to the #GlobalSelfie event page on Facebook or the #GlobalSelfie group on Flickr.
Why a #GlobalSelfie?
NASA scientists have helped identify thousands of new planets out in the universe in recent years. But the space agency studies no planet more closely than our own. With 17 Earth-observing missions orbiting our home planet right now â€” and several more launching this year â€” NASA studies Earthâ€™s atmosphere, land and oceans in all their complexity.
This satellite data helps NASA scientists piece together a clear picture of our planet from a scientific viewpoint. On this Earth Day, NASA wants to create a different picture of our planet â€” a crowd-sourced collection of snapshots of the people of Earth that NASA can use to create one unique mosaic of the Blue Marble.
So, come April 22, take a second to step outside and join NASA in celebrating our home planet.
