NASA’s “Global Selfie” Earth mosaic contains more
than 36,000 individual photographs from the more than 50,000 images posted
around the world on Earth Day, April 22, 2014.

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.
