Welcome to the PDS

The PDS archives and distributes scientific data from NASA planetary missions, astronomical observations, and laboratory measurements. The PDS is sponsored by NASA's Science Mission Directorate. Its purpose is to ensure the long-term usability of NASA data and to stimulate advanced research. All PDS data are publicly available and may be exported outside of United States under "Technology and software Publicly Available" (TSPA) classification. Learn more about PDS.

If you are an individual proposer preparing a proposal to a NASA Research and Analysis (R&A) program, you can start from here.

If you're beginning a new archiving project, you must use PDS4 and you can start from here.

If you're developing a dataset in response to Planetary Data Archiving, Restoration and Tools (PDART), you can start from here.

If you're developing a dataset in response to SMALL INNOVATIVE MISSIONS FOR PLANETARY EXPLORATION (SIMPLEx) , you can start from here.
