"The Landsat Program provides the longest continuous space-based record of Earth’s land in existence. Since 1972, Landsat satellites have collected measurements of Earth’s continents and surrounding coastal regions that have enabled people to study forests, food production, water and land use, ecosystems, geology, and more. The long data record allows scientists to evaluate the dynamic changes caused by both natural processes and human practices. The Landsat Program is jointly managed by the U.S. Geological Survey and NASA." Landsat 8 (formerly the Landsat Data Continuity Mission) was launched on February 11, 2013. It joined Landsat 7 orbiting the earth. These satellites continue to deliver visually stunning and scientifically valuable images of our planet. These data allow scientists to assess changes in Earth’s landscape.

The lava flow itself is bright red. Snow on Klyuchevskaya and nearby mountains is cyan, while bare ground and volcanic debris is gray or brown. Vegetation is green. The image was collected by Landsat 8 on September 9, 2013. NASA Earth Observatory image by Jesse Allen and Robert Simmon, using Earth Explorer." (source: USGS/NASA Landsat)|
