NASA Celebrates Earth Day with "Global Selfie"

For the first time in more than a decade, five NASA Earth-observing missions will be launched into space in a single year. To celebrate this milestone, NASA is inviting people all around the world to step outside on Earth Day, April 22, take a "selfie," and share it with the world on social media.

Designed to encourage environmental awareness and recognize the agency's ongoing work to protect our home planet, NASA's "Global Selfie" event asks people everywhere to take a picture of themselves in their local environment.

On Earth Day, NASA will monitor photos posted to Twitter, Instagram, Facebook, Google+ and Flickr. Photos posted to Twitter, Instagram or Google+ using the hashtag #GlobalSelfie, or to the #GlobalSelfie Facebook event page and the #GlobalSelfie Flickr group will be used to create a crowd-sourced mosaic image of Earth – a new "Blue Marble" built bit-by-bit with #GlobalSelfie photos.

NASA's 17 Earth science missions now in orbit help scientists piece together a detailed "global selfie" of our planet day after day. 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 Earth research also yields many down-to-earth benefits, such as improved environmental prediction and natural hazard and climate change preparedness.

NASA Releases Earth Day "Global Selfie" Mosaic of Our Home Planet

For Earth Day this year, NASA invited people around the world to step outside to take a "selfie" and share it with the world on social media. NASA released Thursday a new view of our home planet created entirely from those photos.

The "Global Selfie" mosaic was built using more than 36,000 individual photographs drawn from the more than 50,000 images tagged #GlobalSelfie and posted on or around Earth Day, April 22, on Twitter, Instagram, Facebook, Google+ and Flickr. The project was designed to encourage environmental awareness and recognize the agency's ongoing work to protect our home planet.

Selfies were posted by people on every continent and 113 countries and regions, from Antarctica to Yemen, Greenland to Guatemala, and Pakistan to Peru. The resulting global mosaic is a zoomable 3.2-gigapixel image that users can scan and explore to look at individual photos. The Global Selfie was assembled after several weeks of collecting and curating the submitted images.

"With the Global Selfie, NASA used crowd-sourced digital imagery to illustrate a different aspect of Earth than has been measured from satellites for decades: a mosaic of faces from around the globe," said Peg Luce, deputy director of the Earth Science Division in the Science Mission Directorate at NASA Headquarters, Washington. "We were overwhelmed to see people participate from so many countries. We're very grateful that people took the time to celebrate our home planet together, and we look forward to everyone doing their part to be good stewards of our precious Earth.”

The GigaPan image of Earth is based on views of each hemisphere captured on Earth Day 2014 by the Visible Infrared Imaging Radiometer Suite instrument on the Suomi National Polar-orbiting Partnership (NPP) satellite. Suomi NPP, a joint mission between NASA and the National Oceanic and Atmospheric Administration, collects data on both long-term climate change and short-term weather conditions.

The Global Selfie is part of a special year for NASA Earth science. For the first time in more than a decade, five NASA Earth Science missions are scheduled to launch in one year. The Global Precipitation Measurement Core Observatory, a joint mission with the Japan Aerospace Exploration Agency, was launched in February. The Orbiting Carbon Observatory-2 is set to launch in July with the Soil Moisture Active Passive mission to follow in November. And two Earth science instruments — RapidScat and the Cloud-Aerosol Transport System — will be launched to the International Space Station.

NASA missions have helped identify thousands of new planets across the universe in recent years, but the space agency studies no planet more closely than our own. With 17 Earth-observing satellites in orbit and ambitious airborne and ground-based observation campaigns, NASA produces data that help scientists get a clearer picture of Earth's interconnected natural systems. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.
