NASA launches Landsat 8 satellite to better study the skies above, water below
Posted in: Today's Chili 
NASA’s Landsat program recently turned the big four-oh, and what better way to deal with the mid-life crisis by getting a new satellite as a present? Accordingly, the space agency has just launched Landsat 8 into orbit to give its Earth Science program a new injection of youth. The new vehicle improves the accuracy of existing light and thermal sensors while widening the scope to better reflect modern climate studies — number 8 now tracks aerosols in the atmosphere, high cirrus clouds and the telltale signs of water quality and consumption levels. We won’t get the first USGS-derived results from the new satellite until after a 100-day shakedown period, but we’re sure the deeper understanding of our planet will help the Landsat program forget all about those first few gray hairs.

The latest Landsat satellite has successfully separated from the Atlas V booster and it’s now alive and well orbiting Earth. It’s the most powerful and modern Landsat satellite yet, the last member of a saga that has provided with vital information to everyone, from farmers to environmental scientists. More »

The Landsat program has revolutionized how we view the Earth during its forty continuous years of operation. The reams of data generated by seven generations of satellites has helped govern both public and private policies from agriculture and forestry management to cartography, geology, and urban planning. The eighth iteration of Landsat is slated for launch next week and is expected to deliver more detailed data than ever. More »

The Landsat satellites have been watching Earth uninterruptedly for a record 40 years. During that time they have acquired millions of amazing images of our home world, available for everyone in the planet. These are the five most beautiful ones, according to NASA. More »

Compared to Landsat, which has been beaming photos of our planet since 1972, Mountain View is a cartographic newb. But Google Earth drove geospatial interest into the stratosphere when it launched in 2005 and, with a billion downloads and counting, the company is well placed to celebrate 40 years of Landsat imagery. To do that, it has collaborated with the US Geological Survey and Carnegie Mellon to create a collection of timelapse videos ranging from seasonal snowcover changes across North America to Amazon deforestation. Though the search giant is gradually shifting from relatively low-res 100 feet per pixel Landsat imagery to 8 feet SPOTImage maps, its Google Earth Engine was used to process the vast archive and make it available to the public. To watch a video of the history of the grand dame of satellite imagery and its liaison with Google, head after the break — or check the source for all the timelapse goodness.

Landsat program celebrates 40 years of continuous observation on Earth from space
Posted in: Today's Chili
Today, the Landsat program is celebrating 40 years of continuous earth observation. In case you don’t know what Landsat is, it’s actually a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. First launched on July 23, 1972, Landsat is now the longest running program for the acquisition of satellite imagery of Earth. Google has partnered with the USGS and Carnegie Mellon University to bring tidbits of images from its vast collection of imagery. The result is the video above.
Highlights of the video include the deforestation of the Amazon forest between 1999 to 2011, as well as the huge growth of Las Vegas between 1999 to 2011. “We believe these may be the largest video frames ever created. If you could see the entire video at full resolution, a single frame would be 1.78 terapixels which is 18 football fields’ worth of computer screens laid side-by-side,” Google said. “Google Earth Engine makes it possible for this data to be accessed and used by scientists and others no matter where they are in the world. Watch the video below to learn more about the history of the Landsat program and how Google Earth Engine was used to process and analyze this enormous archive of planetary imagery.”
