Don Gray, the founder of the Australian Landsat Station, passed away on Tuesday, November 4, 2014. It was through his vision and leadership that the Australian Government invested in the Australian Landsat Station in 1979.
Xploration Outer Space aired an episode on satellites today. The premise of this episode was: “Thousands of satellites orbit the Earth everyday, helping us in ways that we may not even be aware of. But how are they made? Where do they live in [...]
Explorer Stepan Krasheninnikov first pointed it out in 1755: “Perhaps there is no other region in the world where so many volcanoes and hot springs are to be found in so small a space as here on Kamchatka.” There may not be another land mass on [...]
The Landsat satellite series has proven to be a perfect match to the needs of modern irrigated agriculture and water resources management. The 30 m spatial resolution permits the viewing of field scale characteristics of water consumption, which [...]

Along the sea’s edge in Bangladesh, India, Pakistan, and Sri Lanka, the dense coastal population lives largely in symbiosis with the region’s mangrove forests. Mangroves—a vast network of intertidal trees and shrubs with their characteristic [...]
In this natural color Landsat 8 image of New York’s Finger Lake region acquired on Oct. 24, 2014, fall foliage colors of orange, rust, and sage can be seen surrounding the vivid blue lakes, bringing to mind a line from L.M. Montgomery’s Anne of [...]
This Landsat (MSS) image, acquired by Landsat 2 on May 27, 1981 (WRS-1 Path 186 Row 26), marks the one-millionth MSS image acquired by the Landsat satellites. The image covers a 115×115-mile (185×185-km) area of the steppe (vast treeless plain) [...]
Dr. Robert Anemone is the head of the Department of Anthropology at the University of North Carolina at Greensboro. But he works out of a pretty standard office. The administrative assistant greets you in the outer office before gesturing toward [...]

The Landsat calibration team published a number of papers in the SPIE Conference Volume 9218: Earth Observing Systems XIX. Our calibration team (or cal team) is a group of scientists and engineers who work together to ensure the scientific [...]
Interested in Landsat data discovery and access? Landsat satellites have been observing Earth's land surfaces consistently for over 40 years, providing the longest continuous space-based record of Earth’s land in existence. All Landsat data [...]
Earlier this year, I attended a workshop in Arusha, Tanzania to train research scientists from South Africa, Ivory Coast, Mauritania, Botswana, Kenya and Tanzania on how to use products derived from NASA satellites to monitor climate and [...]
The greens and blues of the ocean color from NASA satellite data have provided new insights into how climate and ecosystem processes affect the growth cycles of phytoplankton—microscopic aquatic plants important for fish populations and Earth’s [...]
Land change is a signature activity of human civilization. Since the dawn of history, people have purposefully converted natural landscapes to human-dominated areas. Typical motivations for land change are cultivation (e.g. slash-and-burn [...]
This month in Nature, an emphatic plea to make more Earth satellite imagery free was made by Michael Wulder, a senior research scientist with the Canadian Forest Service and Landsat Science Team member; along with Nicholas Coops, a remote [...]
On public land in the Ivanpah Valley near the California/Nevada border, the world’s largest concentrated solar thermal plant sprawls across the desert landscape. Just on the other side of Interstate 15 (the long straight diagonal line) is the [...]
Much like a symphony, where music is best created when each orchestra member flawlessly executes his or her part, building and launching a scientific satellite takes the expertise, talent, and dedication of a large workforce working to the [...]
Some things go perfectly with a summer trip to the coast: sunscreen, mystery novels, cold beverages, and sand castles. Other things—like algae blooms or polluted runoff—are a lot less appealing. The newest generation of Landsat satellite is [...]
A recent White House-led assessment found that Landsat is among the Nation’s most critical Earth observing systems, second only to GPS and weather. A new USGS study, Landsat and Water — Case Studies of the Uses and Benefits of Landsat Imagery in [...]
During a visit with Confederated Salish Kootenai Tribe leaders of Montana’s Flathead Indian Reservation today, Department of the Interior Secretary Sally Jewell issued a Secretarial order reaffirming the land trust responsibilities of the [...]
This afternoon, Dr. Jim Irons, the NASA Landsat 8 Project Scientist, was awarded NASA’s most prestigious honor—the Distinguished Service Medal—for his leadership and guidance on the Landsat program and Landsat 8 mission.
Ensuring the health and sustainability of the nation’s forests requires scientifically credible and timely information about the extent, location, health, and ownership of these forests and the possible effects of global climate change. Forest [...]
Citizen scientists worldwide are invited to take part in marine ecology research, and they won’t have to get their feet wet to do it. The Floating Forests project, an initiative spearheaded by scientists at UC Santa Barbara and UCLA, is calling [...]
A group of researchers from the University of Maryland, the Indonesian Ministry of Forestry, and the World Resource Institute joined forces to remedy the lack of consensus about the amount of old-growth forest clearing occurring in Indonesia.
Year after year, somewhere on Earth, natural or manmade disasters cause loss of life and widespread destruction, frequently spawning refugee situations. Though the risk of a disaster is low in any one particular place, earthquakes, volcanoes, [...]
Humans have been observing Earth for a very long time simply because the conditions of the Earth are basic to our survival and our prosperity. Even the most ancient written records are filled with accounts of great floods, famines, and [...]
Water availability and allocation are issues gaining a great deal of attention, particularly in arid climates. Increases in population growth and recent droughts bring urgency to measuring and monitoring water use in areas such as the western [...]
On July 23rd, 1972, the first Landsat spacecraft launched into orbit. At the time, it was called “Earth Resources Technology Satellite,” or ERTS, and was the first satellite to use a scanning spectrophotometer. Previous satellites relied on film [...]
The Web-Enabled Landsat Data (WELD) project has released prototype global data sets for climate year 2010. The data sets are available as both monthly and annual 30m products generated from Landsat 5 and 7 data.
Landsat satellites collect data along a wide ground track that spans 185 kilometers (115 miles) but with a spatial resolution that allows them to see the human signature on the landscape. Each Landsat pixel covers a 30 by 30 meter area (98 by 98 [...]
Every full moon, Landsat 8 turns its back on Earth. As the satellite’s orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back around to [...]
Scientists with the Michigan Tech Research Institute are tracking the spread of Chladophora, a hair-fine algae that attaches to shallow water rocks, or the shells of dead invasive zebra and quagga mussels. Occasionally, due to storms in the [...]
