Today marks 40 years since the launch of first satellite program LandSat , the oldest of the space programs of satellite photography to high resolution observation of the earth’s surface. The program is managed by NASA in conjunction with the Geological Survey of the United States and allowed the last 40 years the study of changes caused by humans and nature on the planet.

To celebrate the anniversary, the people of by the USGS (U.S. Geological Survey) and Carnegie Mellon University have launched a series of video of the Earth’s surface under the platform Google Earth Engine – as a way begin to give people the enormous catalog of images, measurable in petabytes, which Landsat have accumulated to orbit the planet every 16 days since July 1972.

The software engineer at Google, Eric Nguyen, explains that “these images can travel through time, from 1999 to 2011 and see the transformation of our planet, whether the deforestation of the Amazon , the urban growth in Las Vegas or how snow covers the land surface through the seasons . “

The people of Mountain View even estimated that these videos may be the most largest available on the web: “If you could see the full video at full resolution, a single frame terapixeles would be 1.78, which are like 18 football fields (American) filled with computer screens placed side by side, “said Nguyen.
