The Landsat program, first known as the Earth Resources Technology Satellite (ERTS) Program, is a development of the National Aeronautics and Space Administration (NASA) in association with NOAA, USGS, and the Space Imaging. The activities of these combined groups led to the concept of dedicated Earth-orbiting satellites, the defining of spectral and spatial requirements for their instruments, and the fostering of research to determine the best means of extracting and using information from the data.  4, record 6, English, - LANDSAT

In 1979, Boeing and the US Air Force Rocket Propulsion Laboratory proposed a small unmanned "Air-Launched Sortie Vehicle", ALSV consisting of a reusable spaceplane and a huge expendable propellant tank. The vehicle could overfly any point on Earth within 90 minutes of the launch order and also perform other military missions such as satellite inspection. It then returns to a military airbase and lands horizontally like the Space Shuttle.  2, record 7, English, - air%2Dlaunched%20sortie%20vehicle
