Habitable Worlds Observatory Instrument Concept Assessments in NASA Research Announcement (NRA): RESEARCH OPPORTUNITIES IN SPACE AND EARTH SCIENCES (ROSES) 2025
NASA will fund concept assessment studies for Habitable Worlds Observatory instruments under ROSES 2025, open to eligible applicants under the solicitation and focused on developing and assessing instrument concepts rather than building flight hardware.
⚑ NASA ROSES special notice; consult the full solicitation text for exact proposal classes and any category-specific rules. · Amendment updated collaborator rules for Category 2 proposals to allow unfunded U.S.-based individuals as collaborators. · Questions accepted until 2026-09-18; proposals due 2026-10-14. · Funding lapse contingency noted: if NASA has a lapse on or after 2026-10-01, check NSPIRES for instructions.
This is a NASA instrument concept assessment call for space-observatory hardware/astrophysics, which is far outside IPPRA’s social-behavioral, policy, and risk-perception portfolio. The team might only touch it tangentially through public-opinion or science-communication angles, but none of the named researchers has this as a plausible PI-level line of work.

Description
Amendment #1 (09/03/2026): This Amendment adds the "2ndEmail" attachment which summarizes the following changes under ROSES-2025 Amendment 73: Section 3.3.2 has been updated regarding Collaborators on Category 2 proposals. It now allows that unfunded U.S.-based individuals involved in the proposed work may be included as Collaborators. New text is in bold in the ROSES Amendment 73. The due date remains unchanged: Proposals are due by October 14, 2026. In addition, the FAQ has also been updated. NASA will accept questions up until September 18, 2026. The attached PDF file labeled “1stEmail” is text that the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) sent to Science Mission Directorate (SMD) List Serv subscribers. This “1stEmail” attachment announces the release of the full text for NNH25ZDA001N-HWOICA as well as summarizes key information from the full text. Visit the link below labeled “NSPIRES page for NNH25ZDA001N-HWOICA” to download the full text. SMD may periodically clarify or amend the solicitation or add other supporting documents. Interested parties should regularly visit the HWOICA NSPIRES page to stay up-to-date on any such changes. In the event of a NASA funding lapse on or after 1 October 2026, please visit NSPIRES.
