Landsat

Space Exploration

A series of US satellites launched from 1972 that monitor the Earth's resources and the effects of pollution, deforestation, and desertification.
Landsat 1, originally called ERTS-A (Earth Resources Technology Satellite-A), orbited 1972–5, acquiring more than 300 000 images of the Earth's surface. Landsat 4, launched in June 1982, contained a new kind of technology, the thematic mapper (TM). The National Oceanic and Atmospheric Administration took over the running of the Landsat programme from NASA in 1983.

Geology and Earth Sciences

A series of satellites, mainly carrying multispectral scanners, and more recently also carrying thematic mappers. They are primarily designed for scanning the vegetation cover of the land surface of the Earth and evaluating the effectiveness of satellite-based scanning systems for routine monitoring. The recordings are available on magnetic tape for computer analysis or in photographic form (usually known as Landsat images). Landsat is complemented by Seasat. Landsat-7 is still operational and is due to be replaced in December 2020 by Landsat-9; Landsat-8 (formerly called the Landsat Data Continuity Mission, LDCM) is also operational.
