This website is about how satellites from space take pictures of how land changes over time. NASA changed the fact that telescopes and other objects only looked out and up by creating the Landsat program. The Landsat program is a series of satellites that orbit our planet looking down.
The program looks to see how humans change the natural world into something else. The USGS (U.S. Geological Survey) and the Space Agency made an amazing catalog with the images that the Landsat program took.
The people working at Google made a video footage from the pictures that NASA gave them. With the help of massive computers, they scrubbed away the clouds to show the land. They filled the land with pixels and put the puzzle pieces together to make the video. The Google workers used 1.8 trillion pixels per frame, the same as 900,000 HD TVs assembled into a single mosaic. These frames the happy and not so happy times of our planet and how humans treat their home planet.
