nasa. gov/APSMEX26 The 2026 Astrophysics SMEX Schedule: AO Release Date: June 9, 2026 Preproposal Conference Date: June 30, 2026 Mandatory Notice of Intent Due Date: July 21, 2026 Proposal Due Date: September 9, 2026 Prospective investigators from any category of organizations or institutions, U.S. or non-U.S. with some restrictions as specified in Section 4. 2.

1 of the AO, are welcome. Read the final APSMEX26 AO text (PDF) carefully for significant changes from the draft (NNH25ZDA008J). Of particular importance is the change in evaluation and selection to a single-step competitive process.

NASA intends to select one investigation proposal from the APSMEX26 responses to proceed into a combined Phase A&B. All proposals must comply with the requirements, constraints, and guidelines contained within the AO. The Science Office for Mission Assessments (SOMA) hosts the official “2026 Astrophysics Small Explorer (SMEX)” website at: https://explorers.

larc. nasa. gov/APSMEX26/SMEX/ where the virtual Preproposal Conference agenda, connection information, the SMEX Program Library and SMEX Question & Answer (Q&A) page are hosted.

Questions or comments about the AO shall be addressed via email to Daniel Moses, Lead Program Scientist, dan. moses@nasa. gov ; Hannah JangCondell, Deputy Program Scientist, hannah.

jang-condell@nasa. gov ; and Omar Torres, Lead Acquisition Manager omar. torres@nasa.

Earth Venture Orbital Solicitation Advance Notice NASA’s Science Mission Directorate intends to solicit the first in a series of innovative, Principal Investigator (PI)-led, cost-capped investigations for operations in Low Earth Orbit (LEO). The full announcement can be found at https://essp.

larc. nasa. gov/EVO-1 This Earth Venture Orbital (EVO) solicitation will focus on: Strategic use of commercial capabilities NASA encourages feedback in response to this Community Announcement.

Questions or comments about this EVO-1 Community Announcement should be submitted by April 23, 2026. The received questions and answers will be posted on the EVO-1 Acquisition Homepage at https://essp. larc.

gov New Frontiers 5 AO Update NASA received comments on the draft New Frontiers 5 Announcement of Opportunity in 2023. The current estimated release of final AO is no earlier than 2026. Comments provided in response to that draft will feed into development of the AO targeted for release no earlier than 2026.

To assist proposers, NASA plans to share the major policies for the next AO approximately 18 months before the targeted release of the AO. Further information will be posted when it is available on the New Frontiers Program Acquisition Website hosted by the Science Office for Mission Assessments (SOMA) at NASA Langley Research Center (LaRC) at https://newfrontiers. larc.

gov/NF5/ Private Sector Activities in Astrobiology, Planetary Protection, and Space Biology RFI: NASA’s Science Mission Directorate (SMD) has released a new Request for Information (RFI) entitled, Private Sector Activities in Astrobiology, Planetary Protection, and Space Biology , seeking expressions of interest from U.S. private sector, academic, nonprofit, and government organizations interested in potential partnerships in astrobiology, planetary protection, and space biology.

This RFI is intended to help NASA identify potential collaborators who can contribute to advancing research, technology development, and applications that support our broader efforts to understand the origins, evolution, and distribution of life in the universe. Please note that the RFI is not a solicitation. NASA does not intend to award contracts, grants, cooperative agreements or Space Act Agreements.

This RFI is voluntary and strictly for planning purposes. Please visit https://go. nasa.

gov/PSPRFI to download a copy of the full RFI. The RFI will be open for at least 60 days following the date of release. All responses must be submitted through the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) by August 10, 2026, to be considered.

Other inquiries may be submitted (using subject line “PSP RFI”) by email to: Email: rebecca. l. mccauleyrench@nasa.

gov 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: https://sti. nasa. gov/new-external-submission-portal/ .

The STI Program invites comments and questions about this new external manuscript submission portal via the Research Access Help Desk at https://sti. nasa. gov/sti-contact-form/?

RequestType=ResearchAccess . 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 https://science.

nasa. gov/researchers/dual-anonymous-peer-review . In our "ROSES" research solicitation we have expanded the number of programs with no fixed due date.

To these no due date programs (including seven in planetary science), proposals may be submitted at any time without any preliminary statement such as a Notice of Intent or Step-1 proposal. For more information see https://science. nasa.
