View from space: U.S. national parks

National Parks Week in the U.S. extends through this weekend, and admission is free at all 397 national parks. If you can’t go, check out these cool photos.

On April 26, 2012, NASA released these wonderful photos of U.S. National Parks as seen from space. The images were acquired over a period of years by various Landsat satellites, which has taught us more about the world we live on than anyone could have imagined before the Landsat program began in the 1970s. NASA released these images in honor of National Parks Week, which started April 21 and extends through tomorrow (April 29). During National Parks Week, all 397 U.S. national parks offer free admission. Go if you can.
