                              NASA missions are obligated to archive their data within PDS so most of the data is related to and in support of NASA missions. Ground-based observers are not required to archive their data (because they are often funded from non-NASA/public sources) but are welcome to 土豆加速器app.
                              


                              Data Analysis Proposals Support
                              

                              Proposers please note: If you are planning to use PDS data for your ROSES data analysis proposal (e.g., Discovery Data Analysis Program, Cassini Data Analysis, Lunar Data Analysis, etc), please note the archive status indicated on the top of each dataset webpage. A status of "archived" or "locally archived" indicates the data are in their final form, while "certified" indicates there are minor editing corrections still to be made. Data sets with other status levels may be either in active development, or considered to have some significant deficiency. Proposers are urged to consult the ROSES solicitation and the appendix for the Program Element to which they are proposing for the specific guidelines on the use of spacecraft data in general and data sets with known issues in particular.
                              



                              Data Release Schedule
                              

                              We have a data release schedule that has the proposed dates of when data provided to the SBN for archiving will be publicly available. This is a proposed schedule and users should not be surprised if missions/projects are late.
