Discovery Data Analysis Program (DDAP)
The ROSES 2024 Discovery Data Analysis Program (DDAP) Appendix C.11
Notice: Starting in ROSES-24, this program element now solicits proposals via a two-step proposal submission process described in Section 2 of C.1 The Planetary Science Division Research Program Overview.
Mandatory Step-1 proposals are due September 5, 2024, and Step-2 proposals are due November 13, 2024.
Proposals to this program will be evaluated using a dual-anonymous peer review process. Both Step-1 and Step-2 proposals must be anonymous. See preparation guidelines in Appendix C.11, Section 3.2 and in the "Guidelines for Anonymous Proposals" document under "Other Documents" on the NSPIRES page for this program element.
Neither NSPIRES cover page budgets nor detailed budgets are requested at the time of proposal submission; proposers must identify the project duration and cost category (small, medium, or large). Please note the dollar thresholds have changed, see C.11, Section 3.3.
New from previous years, the Open Science Data Management Plan (previously the Data Management Plan) for this program will now be a two (2) page section to be included after the references and citations for the S/T/M section of the proposal. See C.11, Section 2.3 and C.1, Secrion 3.7 for more information.
Proposers are strongly advised to read Appendix C.1 in its entirety to help ensure that they have all the necessary information to be compliant with their proposal submission
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 1.1 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 (see using archived data or samples from the following mission 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), Lucy, Magellan, Rosetta and BepiColombo. Proposals must be substantially focused on data analysis from one or more of the missions listed.
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 2.2 for more information.
DDAP is intended to have minimal overlap with other ROSES program elements and DAPs. Consequently, DDAP, does not support work that would be supported under the following ROSES program elements: C.8 LDAP, C.9 MDAP, C.10 CDAP, C.7 NFDAP or D.2. ADAP.
Critical Dates
Step-1 Due Date Data Included in PDS by Step-2 Proposal Due Date
09/05/24 10/14/24 11/13/24
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. The sufficiency of the OSDMP will be evaluated as part of Merit. This section of the proposal must be anonymized. In cases where a letter of support from the Planetary Data System is required, that letter must be included in the separate "Expertise and Resources Not Anonymized" document as outlined in the "Guidelines for Anonymous Proposals" instructions.
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. The archiving of software should be addressed in the OSDMP.
DDAP uses a two-step proposal submission process described in program element C.1, Section 2. Proposers are reminded that Step-1 proposals are mandatory and must be submitted by the proposing organization. Both Step-1 and Step-2 proposals must be written in an anonymized format (see Appendix C.11, Section 3.2 and the "Guidelines for Anonymous Proposals" document for information.
Proposals submitted to this program will be evaluated using a dual-anonymous peer review (DAPR) process. In the DAPR process, proposers are unaware of the identity of the reviewers and the reviewers are not told the identity of the proposers until after the evaluation of the anonymized proposal. The objective of dual-anonymous peer review is to minimize bias in the evaluation of the merit of a proposal. See Section 3.13 of C.1 Planetary Science Research Program Overview and the instructions in the "Guidelines for Anonymous Proposals" document for additional submission instructions.
