The Landsat 6 satellite was a commercial program jointly with the Department of Commerce (NOAA) and EOSAT Company that provided data for a wide range of Earth resources applications including environmental monitoring, natural resource exploration, urban planning, and cartography. The Landsat 6 satellite continued the series of operational Earth resource monitoring spacecraft begun with Landsat 1 in 1972.
The Titan 23G, Titan II(23)G, Titan 2(23)G or Titan II SLV was an American expendable launch system derived from the LGM-25C Titan II intercontinental ballistic missile. Retired Titan II missiles were converted by Martin Marietta, into which the Glenn L. Martin Company, which built the original Titan II, had merged. It was used to carry payloads for the United States Air Force, NASA and NOAA. Thirteen were launched from Space Launch Complex 4W at the Vandenberg Air Force Base between 1988 and 2003.
