Massive City Growth as Seen From Space As captured from the Landsat 3 satellite, this infrared-range image shows the loss of vegetation due to urban growth around China’s Pearl River Delta over a 30 year period. What’s with the colors? Vegetation shows up as red in images like these thanks to the expanded infrared spectrum, and urban areas as gray. You can even see a completely new man-made island pop up in the bottom center! Today this region is home to over 36 million people. More shots of urban growth from space at Wired Science.

itsfullofstars: Landsat Turns Forty In 1965, the U.S. Geological Survey proposed the idea of a remote sensing satellite program to gather facts about the natural resources of Earth. In 1970, NASA had permission to build Landsat 1, which was launched forty years ago this week. Since then, the Landsat series of satellites has collected millions of multi-spectral images that make it possible to study the long-term environmental effects of everything from natural coastal erosion to urban sprawl. The image above was taken by Landsat 7, the newest member of the Landsat family. It shows the delta of the Lena River, one of the largest rivers in the world. The Lena Delta Reserve is the most extensive protected wilderness area in Russia. It is an important refuge and breeding grounds for many species of Siberian wildlife. Source. Beautiful as ever. I guess 40 is the new 20 for geo satellites. Check out Landsat’s all-time greatest “Earth as Art” images to celebrate this milestone.

Fire Devastation in the Western U.S. Seen From Space Here’s the Fort Collins area before the fire (left) and after 60,000 acres had burned (right, fire scar in red) as seen through the Landsat satellites. This has been an unbelievably active week for wildfires in the U.S., with high winds, dry conditions, and a possible look at what long-term climate change could mean for our forests and homes. Many more pictures at the link. Our thoughts are with all of them. (via Wired Science)

Beautiful Images Of Earth: Celebrating 40 Years of Landsat

Since 1972, NASA’s Landsat program has been constantly monitoring Earth from above. Hundreds of images are beamed back from the Landsat satellite from 450 miles above Earth, providing visual data for everything from climate studies to Google Earth.

Here’s a tribute video from NASA, showing how our regular observations of the planet can track geographical changes, natural disasters, and man’s impact on the planet. Viewed from far or near, we have a beautiful home, and one that we still struggle to fully understand.

Bonus: Check out Landsat’s Earth As Art collection! You won’t be sorry, and it should make for some pretty good dashboard fodder, Tumblr friends.
