NASA Landsat Science
The Landsat Project is a series of Earth-observing satellite missions jointly managed by NASA and the USGS. Since 1972, Landsat satellites have collected information about Earth from space. This science, known as remote sensing, has matured with the Landsat Project.
NASA Landsat 8
The Landsat Data Continuity Mission (LDCM) is the future of Landsat satellites. It will continue to obtain valuable data and imagery to be used in agriculture, education, business, science, and government.
The NASA Landsat Project Science Office is teaming with the USGS and the NASA Goddard Space Flight Center Library to create an archive of essential Landsat documentation, including technical, policy, and science related documents with an emphasis on internal technical papers.
