NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day this year with the agency'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 we're 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.
Here are the details.
What's a #GlobalSelfie?
Need an idea of what kind of picture to take? Get outside and show us mountains, parks, the sky, rivers, lakes -- wherever you are, there's your picture. Tell us where you are in a sign, words written in the sand, spelled out with rocks -- or by using the printable signs we've created that are available at the bottom of this 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?
We'll be monitoring photos posted to five social media sites: Twitter, Instagram, Facebook, Google+ and 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 -- and several more launching this year -- NASA studies Earth'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, we wanted to create a different picture of our planet -- a crowd-sourced collection of snapshots of the people of Earth that we could use to create one unique mosaic of the Blue Marble.
So, come April 22, take a second to step outside and join us in celebrating our home planet.
