Future Solicitations

You may download the current planning list of SMD Solicitations (NRAs and AOs) as a PDF from the SOMA web page. ROSES is released each year on or about February 14th. Planned program elements of ROSES are listed in the ROSES tables of due dates as 'TBD' and hypertext links from each title in the table of due dates connects to the NSPIRES page for that program element with a summary and point of contact.

Earth System Explorers AO Final Text Released



Pre-Proposal Conference Date:

May 22, 2023 (Target)

Mandatory Notice of Intent to Propose Due:

May 31, 2023

Proposals Due:

August 2, 2023

Short link to NSPIRES page

The Earth System Explorers (ESE) AO solicits proposals for the development, execution, and data product dissemination of spaceborne missions that make observations of one or more of the 2017 Decadal Survey Earth System Explorer Targeted Observables; however, at least one of the estimated four selected proposals will prioritize Greenhouse Gases as one of its Targeted Observables.

The Science Office for Mission Assessments (SOMA) hosts the Earth System Explorers (ESE) Acquisition website at that provides important information, including the AO’s Program Library and Question and Answer (Q&A) pages.

A Preproposal Conference will be held in the second half of May. SOMA will post the Conference’s forthcoming agenda, logistics, date and time confirmation, etc., on the Preproposal Conference page located on the ESE website provided above. Presentations made at the Preproposal Conference, including answers to all questions addressed at the conference, will be posted on the SOMA Earth System Explorers Acquisition website. 

The deadline for all questions is fourteen (14) days before the proposal due date. Proposers are encouraged to submit questions much earlier so that they may be addressed at the Preproposal Conference. Please address comments or questions on the AO only via email using subject line "ESE 2023 AO” to both the ESE Lead Program Scientist, Dr. Thorsten Markus, at, and the SOMA Acquisition Manager, Mr. Tony Tyler, at

Solar Terrestrial Probes Program DYNAMIC AO Released

Pre-Proposal Conference Date:    June 6, 2023 (target)

Mandatory NOI Due:                        June 30, 2023

Proposals Due:                                 August 22, 2023

Short, Direct URL:                  

NASA has released the final text for the Dynamical Neutral Atmosphere-Ionosphere Coupling (DYNAMIC) Announcement of Opportunity (AO) under the Solar Terrestrial Probes (STP) Program.

The Science Office for Mission Assessments (SOMA) hosts the official “DYNAMIC Acquisition Homepage” that provides further information, including a Program Library and Question and Answer (Q&A) pages. SOMA will post inquiry responses at:

The deadline for all questions is fourteen (14) days before the proposal due date. Proposers are encouraged to submit questions much earlier so that they may be addressed at the Pre-proposal Conference. Anonymity of persons/institutions who submit questions will be preserved. Questions and comments regarding the DYNAMIC AO should be emailed to and

New Frontiers 5 AO Update

Estimated Release of final NF5 AO:      November 2023 (target)
Estimated Proposal due date:               March 2024 (target)

SMD continues to plan to release an Announcement of Opportunity (AO) to solicit New Frontiers Program mission investigations. The New Frontiers Program conducts Principal Investigator (PI)-led space science investigations in SMD’s planetary programs under a not-to-exceed cost cap for the PI-Managed Mission Cost. The target release date for the final AO is Fall 2023.

Based on the availability and readiness of RPS technologies for the NF5 AO:

  •  The NF5 AO will offer up to two fueled Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) units for proposals requiring radioisotope electrical power for spacecraft.
  • The NF5 AO will offer up to twenty fueled radioisotope heater units (RHUs) for proposals requiring thermal heating for specific spacecraft components.

The PI-Managed Mission Cost must cover 1) a portion of the cost(s) for the delivery and integration of MMRTG(s) and/or RHU(s) to the spacecraft and 2) costs for nonstandard nuclear launch services and the nuclear launch approval process. NASA recognizes the community’s urgent need to know these additional costs and is striving to provide them prior to the release of the AO in Fall 2023. 

Further information will be posted on the New Frontiers Program Acquisition Page at as it becomes available. Questions and feedback may be emailed to Dr. Curt Niebur via

2023 Heliophysics Space Weather Focused Mission of Opportunity

As it becomes available, information about a Focused Mission of Opportunity for an extreme ultraviolet (EUV) imager instrument to be hosted on the European Space Agency Vigil mission will be posted on the Vigil FMO Acquisition Website at

Information on Future Portal for Archiving NASA-funded Accepted Manuscripts

The NASA Scientific and Technical Information (STI) Program is developing an external submission portal for NASA-funded investigators to submit Accepted Manuscripts and other STI products. The portal is expected to be available later this summer.

The external portal will be used in place of the National Institutes of Health Manuscripts System (NIHMS), for grant and cooperative agreement recipients. The external portal will provide a more direct and streamlined Accepted Manuscript submission process for recipients. The STI Program will send communications prior to the start date with instructions and reminders.

As part of this transition, an information page about the new portal is available on the STI Program website which will be updated throughout the process:

The STI Program invites comments and questions about this new external manuscript submission portal via the Research Access Help Desk at

Dual-Anonymous Peer Review

In our "ROSES" research solicitation we have expanded the use of dual-anonymous peer review in which, not only are proposers not told the identity their reviewers, the reviewers are not told the identity of the proposers (until after they have evaluated the scientific merit of all of the anonymized proposals). To learn more about dual-anonymous peer review see

No Due Dates?

In our "ROSES" research solicitation we have expanded the number of programs with no fixed due date. Starting in ROSES-2021, proposals to seven programs in planetary science may be submitted at any time without any preliminary statement such as a Notice of Intent or Step-1 proposal. For more information see

Need Advice about ROSES and proposal writing?

On the library and useful links page we have resources that may be useful to those who are new to proposing to ROSES: Links to YouTube versions of presentations given at Goddard in February 2022 at and older by Max Bernstein (NASA HQ) and Christina Richey (JPL) about proposal writing. Both the video of Dr. Richey (thanks to the SETI Institute) and the video of Max Bernstein (thanks to NASA Ames Research Center). Other information that maybe useful to early career/ potential new PIs may be found at
