Developed in 2012 using state-of-the-art video game-engine technology, "Eyes on the Earth" has been enhanced to better deliver interactive reality visualizations of "fresh" data and images from NASA's fleet of Earth satellites to home computers. It is directly linked into NASA's "Earth Right Now" media campaign to keep the public informed about what NASA has dubbed "The Year of the Earth." For the first time in more than a decade, five NASA Earth science missions will be launched into space in the same year, providing new insights into our planet. "Eyes" will inform you about these missions so you can keep your views up to date on the latest developments. As these NASA satellite missions constantly monitor our planet's vital signs, "Eyes" will allow the viewer to virtually ride along with a satellite observing the Earth as it sweeps below, and view authentic data maps of ozone, carbon dioxide distribution, and global temperature mapped onto the surface of the globe. A touchscreen version has been developed for broadcast studio use as well as for museums and science centers.
The iOS and Android app "Earth Now" brings a world of ever-changing weather and climate data to your mobile devices. The regularly updated data are displayed as color maps projected over a 3D Earth model that can be rotated by a single finger stroke, or zoomed in and out by the pinch or spread of two fingers. Color-coded legends indicate the relative strength or weakness of environmental conditions. Helpful descriptions provide background information on each data set. "Earth Now" is currently available at the iTunes app store and Google Play.
