EARTH OBSERVATION
NASA Sees Earth From Orbit In 2013
by Staff Writers
Greenbelt MD (SPX) Apr 23, 2014


Satellites help bring us discoveries - like the "mega-canyon," longer than the Grand Canyon, found under a mile of Greenland ice.

A fleet of orbiting satellites monitors Earth constantly. The satellites from NASA and other space agencies give us a fresh, wide perspective on things that we can see from the ground - and things that we can't.

A look back at Earth in 2013 from the viewpoint of orbit reveals the kind of data gathering and technical achievement that are the reason NASA puts Earth-observing satellites in space.

A visualization of satellite and computer model data shows how a cloud of dust from the Chelyabinsk meteor moved around the world. NASA satellites measured the intensity of wildfires, the salinity of the oceans and rainfall around the globe - whether it was too little or too much.

Satellites also helped bring us discovery - like the "mega-canyon," longer than the Grand Canyon, found under a mile of Greenland ice. Meanwhile, far from the world's ice sheets, scientists used a new technique to measure the fluorescence of plants. The visualized result shows a glowing world that is both awe-inspiring and instructive.

The satellite view of Earth allows for everything from the terrifying to the peaceful. Satellites gave us imagery of typhoon Usagi rapidly intensifying and they gave us humbling images of a storm that spawned tornadoes in Oklahoma.

Satellites also showed us how the seasons change, and how the world looks from above, on the International Space Station, as the Earth spins and night turns to day.

NASA works to better understand and protect our home planet. Our data and research helps improve environmental prediction and prepare for natural hazards and climate change. In 2014, five NASA missions are launching to space - the most active year for NASA Earth science in more than a decade.

NASA calls on Earthlings to celebrate Earth Day with #GlobalSelfie
Washington (UPI) Apr 22, 2013
To celebrate planet Earth and Earth Day, NASA has called on citizens of Earth to take a #GlobalSelfie. But, what is a #GlobalSelfie? Put simply, it's a selfie. As NASA explains it, a #GlobalSelfie is a self-taken portrait of Earth's inhabitants. Snap a selfie and post it to one of five social media networks, including Twitter, Instagram, Facebook, Google+ and Flickr, with the hashtag #G ... read more
