Landsat Program

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the USGS. 

In cooperation with NASA, the Earth Resources Technology Satellite (later renamed Landsat 1, LS1) was launched in 1972. Additional Landsat satellites were launched in the 1970s and 1980s, followed by Landsat 7 (LS7) in 1999. Landsat 8 (LS8) was the most recent satellite to be launched on 11 February 11 2013. Landsat 9 (LS9) is in development, with launch scheduled for late 2020.  

The instruments aboard the Landsat satellites have acquired millions of images through the course of the missions, and the data is a valuable resource for global change research and applications in agriculture, forestry, geology, regional planning, and education.
