The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. Since 1972, Landsat satellites have collected information about Earth from space. This science, known as remote sensing, has matured with the Landsat Program.

Landsat 1 (formerly named Earth Resources Technology Satellite -ERTS-1-) was launched on July 23, 1972. The launches of Landsat 2, Landsat 3, and Landsat 4 followed in 1975, 1978, and 1982, respectively.
When Landsat 5 launched in 1984, no one could have predicted that the satellite would continue to deliver high quality, global data of Earth’s land surfaces for 28 years and 10 months, officially setting a new Guinness World Record for "longest-operating Earth observation satellite." Landsat 6 failed to achieve orbit in 1993.
Landsat 7 successfully launched in 1999 and, along with Landsat 8, which launched in 2013, continues to provide daily global data. Landsat 9 is planned to launch in late 2020.

Sensor characteristics

Sensor name MSS1 (Multispectral Scanner 1)
Sensor short description

These scanners were identical to those on the first two Landsat satellites. The only difference was that the four spectral bands were numbered from 1 to 4 since the RBVs were no longer used. Landsat 5’s MSS stopped acquiring data in 1992.

Sensor type Imaging radiometer (Vis/IR)
Resolution class Medium (30 - 300 m)
Spatial resolution 68 m x 83 m
Spectral bandwidth Band 1: 0,5 - 0,6 µm - Coastal zones, marine sediments
Band 2: 0,6 - 0,7 µm - Roads and urban areas
Band 3: 0,7 - 0,8 µm - Plant studies and mapping of earth/water boundaries
Band 4: 0,8 - 1,1 µm - Plant studies and mapping of earth/water boundaries
Swath width (at nadir) 185 km
Sensor name RBV1 (Return Beam Vidicon 1)
Sensor short description
Sensor type Imaging radiometer (Vis/IR)
