Discovery Data Analysis Program (DDAP)
The ROSES 2023 Discovery Data Analysis Program (DDAP)   Appendix C.11
Notice: This program element uses a mandatory Notice of Intent, see C.11, Section 6.1 for more information.
Mandatory Notice of Intent (NOI) is due August 6, 2023, and Step-2 Proposals are due November 2, 2023.
Neither NSPIRES cover page budgets nor detailed budgets are requested at the time of proposal submission; proposers must merely identify the project duration and cost category (small, medium, or large). Please note the dollar thresholds have changed, see C.11, Section 7.3.
The Open Science and Data Management Plan is not a separate 2-page section but must be included in the 15-page S/T/M section of the proposal, see C.11, Section 4.3.
Proposals to this Program Element will be evaluated using dual-anonymous peer review. Proposals must be prepared following the guidelines in C.11, Section 6.2 and the "Guidelines for Anonymous Proposals" document.
NASA's Discovery Data Analysis Program (DDAP) advances the planetary sciences through research based on select missions of NASA’s Discovery Program, ESA’s Rosetta and BepiColombo missions, and select other missions with important synergies for the Discovery program. DDAP’s objectives are to enhance the scientific return of these missions by supporting new analyses, approaches and interpretations of data and samples. See C.11, Section 2 for Significant Changes from recent years.
NASA’s Discovery Data Analysis Program (DDAP) solicits proposals to pursue any research topic that advances the Planetary Science goals articulated in the NASA 2018 Strategic Plan and 2020 Science Mission Directorate Vision for Scientific Excellence ( using archived data or samples from the following missionsn list, limited to data collected by these missions for non-Earth targets within the Solar System:

NEAR, Stardust, Stardust-NExT, Genesis, Deep Impact, EPOXI(only for targets within the Solar System and only non-Earth targets), MESSENGER, Dawn, Kepler/K2 (only for targets within the Solar System), Magellan, Rosetta and BepiColombo.

DDAP is a science program, and all proposals must be framed around a scientific investigation with science outcomes. This program element encourages proposers to implement Open Science (OS) approaches consistent with the recommendations of the report Open Science by Design: Realizing a Vision for 21st Century Research from the National Academies of Science, Engineering and Medicine . See C.11, Section 4 for more information.
Critical Dates
NOI Due Date Data Included in PDS by Step-2 Proposal Due Date
09/06/23 10/03/23 11/02/23
Mission data are available from the Planetary Data System (PDS).
Data Available at PPI
Other Data Within PDS
The following Discipline Nodes have additional information (may be in lien resolution):
Atmospheres Node
Cartography and Imaging Sciences Node
Geosciences Node
Small Bodies Node
Ancillary data (SPICE files) can be obtained from the NAIF Node
Data used in DDAP investigations must be available in the Planetary Data System (PDS) or equivalent publicly accessible archive, at least 30 days prior to the Step-2 due date for DDAP proposals. Analysis of scientific data, samples, and other observations that is not available in such archives is not eligible for support in DDAP investigations. The calendar of record for data released in the PDS is the PDS Data Release Calendar.
Proposals submitted to this program element must include an Open Science and Data Management Plan (OSDMP). Information on the content of a OSDMP may be found in Section 3.7 of C.1 the Planetary Science Research Program Overview.. For this program element the OSDMP must be included in the 15 page Science/Technical/Management Section of the proposal.
All proposals must include a letter of support from the manager of the appropriate PDS data node. Such letters should be included in the "Expertise and Resources – Not Anonymized" document. For additional information, refer to the PDS Proposer's Archiving Guide.
All data products produced by funded DDAP investigations must be made publicly available, following the guidelines described in C.1 Planetary Science Research Program Overview.
All software developed under this program element is to be designated and distributed to the public as open-source software using Apache License 2.0 ( or a less restrictive license. Software developed under this program may be created to operate in conjunction with commercial or other restricted-use software (such as MATLAB, ENVI, and ArcGIS), but must be licensed separately from that software.
Proposals submitted to this Program Element must follow all formatting requirements that are described in program element C.1 , and Section IV(b)ii of the ROSES Summary of Solicitation and in the NASA Guidebook for Proposers. Violation of these rules is sufficient grounds for a proposal to be rejected.
