The PGG program supports research investigations relevant to the scientific interpretation of data from past and existing planetary missions, as well as the science objectives of future missions. In addition, the program supports the development and production of cartographic products of planetary data sets. Proposals to study or develop flight instruments or study future planetary missions are beyond the scope of this program. The Planetary Aeolian Facility at the NASA Ames Research Center consists of wind tunnels to simulate atmosphere-surface interactions on Earth, Mars, and Venus. The NASA AVGR is a national facility funded by the NASA Office of Space Sciences to enable investigations of impact phenomena and processes.
More extensive programs are subject to review in order to assess feasibility and cost effectiveness.
Data Sources Available for the PGG Program Prospective proposers should be aware of sources for data that might be used in their research and whether the required data are available. Investigators are responsible for acquiring the data needed for their proposal. Modest requests for imaging and nonimaging data are free of charge, while charges will be made for large requests. A variety of planetary cartographic products such as topographic, orthophoto, geological, and other special maps and geodetic information are available. Requests from NASA-funded investigators for production of special maps or other cartographic materials will be accommodated when possible.
