Funding Opportunities


On May 27, 2021, the Biological and Physical Sciences Division released the Multi-Agency Solicitation Extended Longevity of 3D Tissues and Microphysiological Systems for Modeling of Acute and Chronic Exposures to Stressors focused on adapting existing 3D tissues and microphysiological systems (MPS), also known as "tissue chips" or "organs-on-chips", to extend the current longevity of the 3D tissues and MPS to at least 6 months. The full text of this NRA and associated documentation can be found at: Step-1 Proposals are due Jun 28, 2021.




The Third Stand Alone Missions of Opportunity Notice (SALMON-3 = NNH17ZDA004O) Announcement of Opportunity (AO) is an omnibus, meaning it hosts individual flight opportunities each with its own topic and due date. The Table of SALMON-3 PEA Due Dates has hypertext links to each program element appendix (PEA) in SALMON-3.

Geospace Dynamics Constellation Salmon PEA Mandatory NOIs Due June 23, 2021

Mandatory NOIs: June 23, 2021
Proposals: September 1, 2021

Geospace Dynamics Constellation (GDC) is being formulated as a spacecraft constellation of at least six observatories with homogenous science payloads. The mission will focus on high-priority science identified by the GDC Science and Technology Definition Team and refined as part of NASA’s pre-Phase A activities.

The GDC SALMON PEA NNH17ZDA004O-GDC solicits science investigations that 1) will address the NASA-identified GDC Science Objectives with investigation team members that will join the GDC science team for Phases A through F, and 2) will deliver flight instruments for integration on the GDC observatories.

A Preproposal Conference will be held via teleconference/WebEx in mid-June, 2021. The forthcoming date, agenda, and logistical information for this session may be found by searching the Acquisition Homepage:

Comments and questions may be addressed by email to Dr. Jared Leisner at Proposers are encouraged to send comments and questions early, so that they may be addressed at the Preproposal Conference.

SIMPLEx AO No Earlier Than April 2021.

There will be a delay in the release of the Small Innovative Missions for Planetary Exploration (SIMPLEx) Announcement of Opportunity (AO). Previously, the planetary science division had announced at town hall meetings that the SIMPLEx AO would be released no earlier than September 2020, but it is now anticipated that the SIMPLEx AO will be released no earlier than April 2021. Any inquiries should be directed to the SIMPLEx email:

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.

Delay of New Frontiers to June 2027

Estimated Release of draft AO ………….…. October 2023 (target)
Estimated Release of final AO ……..…….... October 2024 (target)
Estimated Proposal due date …………........       90 days after AO release

Community announcement NNH20ZDA016L notified potential proposers of the decision to delay the release of the next New Frontiers AO. The new target is no later than fall 2024 for the release of the final AO. This is a delay of approximately two years compared to the November 5, 2020 announced target date of October 2022 that was posted on both on as a "special notice" and as a community announcement on NSPIRES.

The launch date for Dragonfly, the fourth mission in the New Frontiers Program, has been delayed to June 2027. This delay of the Dragonfly launch date is not a reflection on the progress and performance of the Dragonfly project. Rather, the delays are driven by other missions being in peak development and COVID-related challenges in the broader Planetary Science Division portfolio. The updated AO schedule estimate allows selection of the fifth New Frontiers mission at around the time of Dragonfly’s launch, thereby avoiding the budget strain of having two New Frontiers missions in development at the same time.

The new AO release date places the fifth New Frontiers mission firmly in the time period being deliberated upon by the ongoing planetary science decadal survey. NASA SMD intends to use the results of this decadal survey, expected in early 2022, to guide the New Frontiers 5 AO.

NASA has not approved the issuance of the New Frontiers AO and this notification does not obligate NASA to issue the AO and solicit proposals. Any costs incurred by prospective investigators in preparing submissions in response to this third notification or the planned Draft NF5 AO are incurred completely at the submitter's own risk.

Further information will be posted on the New Frontiers Program Acquisition Page at as it becomes available. Address questions and comments on this third community notice to Dr. Curt Niebur at


Community Announcements


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 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
