Launched on February 11, 2013, Landsat 8 (formerly the Landsat Data Continuity Mission, LDCM) is the future of Landsat satellites. It is collecting valuable data and imagery to be used in agriculture, education, business, science, and government.
The Landsat Program provides repetitive acquisition of high resolution multispectral data of the Earth’s surface on a global basis. The data from Landsat spacecraft constitute the longest record of the Earth’s continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value.

- Fire, floods, hurricanes, tornadoes, and other natural disasters can be particularly tragic and costly when critical facilities such as power plants, airports, roads, and hospitals are threatened. When a disaster strikes, remote sensing is often the only way to get a big-picture view of what is happening on the ground.
- With its consistent, reliable, repeated observations of Earth’s changing surface, Landsat keeps a record of Earth’s land surfaces before and after disasters, serving as an essential tool for assessing risk, mapping the extent of damage, and planning post-disaster recovery. Landsat produces 185-kilometer-wide images with 30-meter resolution in visible and infrared wavelengths of light, making it possible to map impacts on the landscape in ways otherwise not visible to human sight. For example, Landsat sensors enable us to see the heat from fires both during and after the burns, and the lava flows from volcanic eruptions even when gaseous substances obscure the view to human eyes.
