Landsat Contest Offers View Of Local Landscape Change From Space
2012-05-25 03:16:22

To celebrate the 40th anniversary of the United States' Landsat Earth-observing program, NASA and the U.S. Geological Survey (USGS) are holding a contest that will offer winners customized satellite views of changing local landscapes. All U.S. citizens are eligible to enter the "My American Landscape: A Space Chronicle of Change" contest. Winners will be announced on July 23 at a Landsat Program anniversary news conference in Washington, which will be carried live on NASA Television. The...

Spotlight on Sentinel-2
2012-05-07 03:19:57

The vast potential of ESA´s upcoming Sentinel-2 satellites came into focus last week at a symposium in Italy on how they will benefit current and future projects that exploit Earth observation data. The humid and moist tropical climate of Gabon yields immense forests that cover over 85% of the land, making them the number-two driver of the national economy — and deforestation a subject of concern. The GMES project on Forest Monitoring Reducing Emissions from Deforestation and...

Landsat Captures Texas 'Crop Circles'

[ Watch the Video ] A water-rich polka dot pattern takes over the traditional rectangular patchwork of fields in this time series animation of 40 years of Landsat images. In the dry Texas panhandle near the town of Dalhart, this transformation is due to center-pivot irrigation, a farming method that improves water distribution to fields. It was invented by farmer Frank Zybach in 1949. Center-pivot irrigation works by pumping water from the center of the field through a long pipe that...

Over dinner on R.V. Calypso while anchored on the lee side of Glover´s Reef in Belize, Jacques Cousteau told Phil Dustan that he suspected humans were having a negative impact on coral reefs. Dustan–a young ocean ecologist who had worked in the lush coral reefs of the Caribbean and Sinai Peninsula–found this difficult to believe. It was December 1974. But Cousteau was right. During the following three-plus decades, Dustan, an ocean ecologist and biology professor at the...

Image 1 - Study Shows More Shrubbery In A Warming World
2011-12-10 04:25:14

Scientists have used satellite data from NASA-built Landsat missions to confirm that more than 20 years of warming temperatures in northern Quebec, Canada, have resulted in an increase in the amount and extent of shrubs and grasses. "For the first time, we've been able to map this change in detail, and it's because of the spatial resolution and length-of-record that you can get with Landsat," says Jeff Masek, the program's project scientist. He's based at NASA's Goddard Space Flight Center...

Image 1 - Landsat Tracks Yellowstone's Underground Heat

Yellowstone National Park sits on top of a vast, ancient, and still active volcano. Heat pours off its underground magma chamber, and is the fuel for Yellowstone´s famous features -- more than 10,000 hot springs, mud pots, terraces and geysers, including Old Faithful. But expected development by energy companies right outside Yellowstone´s borders have some fearing that Old Faithful could be cheated out of its energy. "If that geothermal development outside of the park begins,...

Image 1 - Kirtland’s Warblers Prefer Forests After Fire
2011-12-08 04:59:28

Kirtland´s warblers are an endangered species of lightweight little birds with bright yellow-bellies that summer in North America and winter in the Bahamas. But be it their winter or their summer home, a new study using data from NASA-built Landsat satellites shows that these warblers like to live in young forests and often forests that have been on fire. The U.S. Fish and Wildlife Service listed Kirtland´s warblers as endangered in 1967 after a startling decline of over 50...
