! Instrument !! Picture !! Launched !! Terminated !! Duration !! Notes
|-
| [[Landsat 1]] || [[File:Sketch of ERTS-1 renamed Landsat1.jpg|100px|Landsat 1]] || 23 July 1972 || 6 January 1978 || {{Age in years, months and days|1972|06|23|1978|01|06}} || Originally named Earth Resources Technology Satellite 1. Landsat 1 carried two vital instruments: a camera built by the [[RCA|Radio Corporation of America]] (RCA) known as the Return Beam Vidicon (RBV); and the Multi spectral Scanner (MSS) built by the [[Hughes Aircraft Company]].
|-
| [[Landsat 2]] || [[File:Landsat-1.jpg|100px|Landsat 2]] || 22 January 1975 || 25 February 1982 || {{Age in years, months and days|1975|01|22|1982|02|25}} || Nearly identical copy of Landsat 1. Payload consisting of a Return Beam Vidicon (RBV) and a Multi spectral Scanner (MSS). The specifications of these instruments were identical to Landsat 1.
|-
| [[Landsat 3]] || [[File:Landsat3.jpg|100px|Landsat 3]] || 5 March 1978 || 31 March 1983 || {{Age in years, months and days|1978|03|05|1983|03|31}} || Nearly identical copy of Landsat 1 and Landsat 2. Payload consisting of a Return Beam Vidicon (RBV) as well as a Multi spectral Scanner (MSS). Included with the MSS was a short-lived thermal band. MSS data was considered more scientifically applicable than the RBV which was rarely used for engineering evaluation purposes.  
|-
| [[Landsat 4]] || [[File:Landsat5.jpg|100px|Landsat 4]] || 16 July 1982 || 14 December 1993 || {{Age in years, months and days|1982|07|16|1993|12|14}} || Landsat 4 carried an updated Multi Spectral Scanner (MSS) used on previous Landsat missions, as well as a Thematic Mapper.
|-
| [[Landsat 5]] || [[File:Landsat5.jpg|100px|Landsat 5]] || 1 March 1984 || 5 June 2013 <ref>{{cite web|url=http://landsat.gsfc.nasa.gov/?p=5596|title=Historic Landsat 5 Mission Ends - Landsat Science|date=26 June 2013}}</ref> || {{Age in years, months and days|1984|03|01|2013|06|05}} || Nearly identical copy of Landsat 4. Longest Earth-observing satellite mission in history. Designed and built at the same time as Landsat 4, this satellite carried the same payload consisting of a Multi Spectral Scanner (MSS) as well as a Thematic Mapper.
|-
| [[Landsat 6]] || [[File:Landsat-6.jpg|100px|Landsat 6]] || 5 October 1993 || 5 October 1993 || 0 days || Failed to reach orbit. Landsat 6 was an upgraded version of its predecessors. Carrying the same Multi spectral Scanner (MSS) but also carrying an Enhanced Thematic Mapper, which added a 15m resolution panchromatic band.
|-
| [[Landsat 7]] || [[File:Landsat7photo.jpg|100px|Landsat 7]] || 15 April 1999 || Active || {{Age in years, months and days|year=1999|month=4|day=15}}
|Operating with scan line corrector disabled since May 2003.<ref>{{cite web |title=Landsat Science |url=http://landsat.gsfc.nasa.gov/}} {{PD-notice}}</ref> The main component on Landsat 7 was the Enhanced Thematic Mapper Plus (ETM+). Still consisting of the 15m-resolution panchromatic band, but also includes a full aperture calibration. This allows for 5% absolute [[radiometric calibration]].<ref>{{cite web |title=Landsat 7 - Landsat Science |url=https://landsat.gsfc.nasa.gov/landsat-7-2/ |archive-url=https://web.archive.org/web/20161108221655/http://landsat.gsfc.nasa.gov/landsat-7-2/ |archive-date=2016-11-08 |access-date=2017-03-19 |website=landsat.gsfc.nasa.gov}} {{PD-notice}}</ref>
