The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, ...
Landsat 9 is an Earth observation satellite launched on 27 September 2021 from Space Launch Complex-3E at Vandenberg Space Force Base on an Atlas V 401 launch vehicle. [3] NASA is in charge of building, launching, and testing the satellite, while the United States Geological Survey (USGS) operates the satellite, and manages and distributes the data archive. [4]
Landsat 8 is an American Earth observation satellite launched on 11 February 2013. It is the eighth satellite in the Landsat program and the seventh to reach orbit successfully. Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USGS).
IKONOS was a commercial Earth observation satellite, and was the first to collect publicly available high-resolution imagery at 1- and 4-meter resolution.It collected multispectral (MS) and panchromatic (PAN) imagery.
In addition to that, the satellite will support a global AIS mission and amateur radio communication. The satellite payload is a four-band push broom multi-spectral imaging camera (Landsat band: B, G, R, NIR), which will give a resolution of 18 m and coverage of 120 km from 650 km altitude. The satellite was launched in June 2016. [4] [15]
Landsat 5 significantly exceeded its designed life expectancy, lasting several decades beyond its original three-year mission. Contributing to Landsat 5's longevity was the presence of extra fuel for possible future retrieval by the Space Shuttle. [11] If the need arose, Landsat 5 could use the extra fuel to move into a lower orbit.
Landsat 6, equipped with upgraded versions of the instruments on Landsat 5, was designed to carry forward the Landsat program. It was launched on October 5, 1993, with a Titan II launch vehicle, but failed to reach orbit. Landsat 6 omitted the Multi-Spectral Scanner found on its predecessors, but carried an Enhanced Thematic Mapper, which ...
Landsat 3 is the third satellite of the Landsat program. It was launched on March 5, 1978, with the primary goal of providing a global archive of satellite imagery. Unlike later Landsat satellites, Landsat 3 was managed solely by NASA. Landsat 3 decommissioned on September 7, 1983, beyond its design life of one year. [2]
