Today [July 23, 2012] we celebrate the 40th anniversary of the Landsat satellite program — now the longest-running continuous acquisition of satellite images of the Earth’s surface. Over the years, Landsat has collected petabytesof images offering an historic perspective on planetary change that can help scientists, independent researchers, and nations make informed economic and environmental policy decisions.
We’re working with the USGS and Carnegie Mellon University, to make parts of this enormous collection of imagery available to the public in timelapse videos of the Earth’s surface. With them you can travel through time, from 1999-2011, to see the transformation of our planet.
