Landsat 40th Anniversary
The Landsat satellites have been orbiting since 1972. The first Landsat, formerly known as ERTS-1, was launched as an experimental project to see if satellites could be used to image the landscape and provide useful information regarding land use change. Today these satellites provide invaluable data covering a realm of diverse uses from urbanization to resource management, natural disaster and hazard monitoring to mapping habitat and diversity changes. With the USGS Landsat Archive now downloadable at no cost to users, new innovations are developed regularly with uses for Landsat data. With 40 years of data, change over time is something that can easily be shown with this archive.
Our mission partner, NASA, has created this video, summarizing the value of 40 years of global Landsat data.
The LandsatLook Viewer Now Available
On July 23, 2012, on the 40th Anniversary of the launch of Landsat 1, the USGS Landsat Project rolled out a new tool that enables fast and easy viewing of 3 million Landsat images all around the globe with just a simple web browser. We have made exporting your display and downloading full scenes easy, but the real power of the LandsatLook Viewer is the capability to explore Earth. With a placename search tool or panning and zooming, you can easily navigate the globe. Be sure to check out the 40 years of data over your favorite place!
Whether you are preparing a presentation, teaching kids, educating decision makers, or previewing the full-resolution image prior to downloading the full scenes, the LandsatLook Viewer is a new and exciting way to experience the Landsat archive.
Landsat Stories - The Uses and Benefits of Landsat Data
The 40 year archive of Landsat data is a valuable resource, supporting many different areas of focus for all users. On the Landsat in Action Web page, we have started with stories of two data users, who want to share the benefits of Landsat data - from aircraft runways in the Aleutian Islands in Alaska, to field-level mapping in Brazil and Paraguay.
We invite you to send us your story on how Landsat data has helped with your projects... send your stories to email@example.com.

Landsat Image of Interest - Western Wildfires
Wildfires are doing severe damage in a number of western U.S. states. Extremely dry conditions, stiff winds, unusually warm weather, and trees killed by pine bark beetle outbreaks have created a situation in which major fires thrive. 52 active fires in a number of states have destroyed over 900,000 acres. Since the beginning of 2012, 27,000 fires have destroyed 1.9 million acres.
The immediate impact is loss of property and lives. Longer term, the exposed soil profiles, especially in steep-sloped regions, will affect erosion, make the areas vulnerable to potential flooding, and affect water quality.
Landsat satellite data are being used to record the rate of burning, extent of damage, and the results of efforts to control the burns. The data will be used by resource managers to monitor regrowth and rehabilitation after the fires are controlled.
