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.

nasa. gov/NF5/ 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.
