In recent years, the demand for improved management of Earth resources has increased. At the same time, the proven ability of Earth-orbiting satellites to obtain accurate and timely information for this management has been demonstrated several times. Return Beam Vidicons (RBV) and Multispectral Scanners (MSS) are orbiting now, the Thematic Mapper (TM) is slated for a near-term Shuttle launch, and advanced definition is being done to determine technology capability of the next generation Earth resources satellites. This conceptual system will likely utilize "pushbroom" (linear arrays normal to orbital track using the orbital velocity to provide a 2-dimensional map) techniques with one linear array for each of the spectral bands required for information gathering. This discussion takes user requirements, as determined by NASA, and considers the possibility of using a preliminary system derived for those requirements to gather similar information on other planets. Relative levels of solar irradiance, planetary characteristics, and other solar system information have been used to find possible orbits, comparative signal-to-noise, ranges of sun-synchronous orbits, and other information regarding possible operation of this Earth-oriented system for other planets.
