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.
Lockheed Martin's Space Division started in the production of missiles and later ICBM's in the 1950s. Their TITAN missile system was used for 12 Gemini spacecraft and the Voyager probes. They have worked largely in collaboration with NASA on many of their probes, landers, and spacecraft, and hope to play a key role in NASA's return to the moon in 2024.
The Coriolis / Windsat / SMEI three-year mission will provide Defense Department and National Oceanic and Atmospheric Administration (NOAA) weather data users with important ocean wind and solar wind measurements -- improving forecasting around the globe while building important knowledge that will be used in developing the next generation of Polar-orbiting environmental satellites.
Sun-Synchronous OrbitThe NOAA K, L and M POES satellites begin the fifth generation of improved environmental monitoring in support of NOAA missions. The instrument payload has significant improvements and additions/deletions. The instrument changes have effected the spacecraft subsystems and data formats.
Sun-Synchronous OrbitThe SeaWinds instrument on the QuikScat (Quick Scatterometer) mission is a "quick recovery" mission to fill the gap created by the loss of data from the NASA Scatterometer (NSCAT), when the ADEOS 1 host satellite lost power in June 1997. The SeaWinds instrument is a specialized microwave radar that measures near-surface wind speed and direction under all weather and cloud conditions over the Earth's oceans.
Polar OrbitThe NOAA K, L and M POES satellites begin the fifth generation of improved environmental monitoring in support of NOAA missions. The instrument payload has significant improvements and additions/deletions. The instrument changes have effected the spacecraft subsystems and data formats.
Sun-Synchronous OrbitThe DSPSE (Deep Space Program Science Experiment), the first of a series of Clementine technology demonstrations jointly sponsored by the Ballistic Missile Defense Organization (BMDO) and the National Aeronautics and Space Administration (NASA), launched in early 1994. Its principal objective is to space qualify lightweight imaging sensors and component technologies for the next generation of Department of Defense (DoD) spacecraft. The Clementine mission uses the Moon, a near-Earth asteroid (1620 Geographos), and the spacecraft's Interstage Adapter (ISA) as targets to demonstrate lightweight component and sensor performance.
Lunar OrbitThe 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.
