About this file
This is an amendment to a NASA Research Announcement (ROSES-2025) that provides a correction to the D.9 Habitable Worlds Observatory Instrument Concept Assessments (HWO-ICA) program element.
The HWO-ICA program solicits proposals to support maturation of the HWO mission concept, with objectives focused on expanding exploration of the HWO instrument trade space through development and analysis of innovative instrument concepts, their scientific opportunity and performance, engineering feasibility and footprint, technology maturity and gaps, and associated risks. ROSES-2025 Amendment 73 makes a correction to Section 3.3.2 regarding collaborators on category 2 proposals, with new text presented in bold formatting. The proposal due date remains October 14, 2026. NASA will accept questions regarding the program element until September 18, 2026, with the FAQ updated on the NSPIRES program page. The amendment is scheduled for posting on or about September 3, 2026, on the NASA research opportunity homepage at https://solicitation.nasaprs.com/ROSES2025 and on SARA's ROSES blog. Questions concerning D.9 HWO-ICA may be directed to Megan Ansdell at Megan.C.Ansdell@nasa.gov. The announcement references NASA Research Announcement identifier NNH25ZDA001N.

Subject: ROSES-25 Amendment 73: D.9 Habitable Worlds Observatory Instrument Concept Assessments: Correction regarding collaborators on category 2 proposals.
Habitable Worlds Observatory (HWO) Instrument Concept Assessments (HWO-ICA) program element D.9 of ROSES-25, solicits proposals to support maturation of the HWO mission concept. The objective of HWO-ICA is to expand and deepen exploration of the HWO instrument trade space by developing and/or analyzing innovative instrument concepts and their scientific opportunity and performance, engineering feasibility and footprint, technology maturity and gaps, and associated risks
ROSES-2025 Amendment 73 makes a correction to Section 3.3.2 of D.9 Habitable Worlds Observatory Instrument Concept Assessments (HWO-ICA) regarding collaborators on category 2 proposals. New text is in bold. The due date remains unchanged: Proposals are due by October 14, 2026.
Also, the FAQ (posted under other documents on NSPIRES page for this program element) has been updated. NASA will accept questions up until September 18, 2026.
On or about September 3, 2026, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2025" (NNH25ZDA001N) will be posted on the NASA research opportunity homepage at https://solicitation.nasaprs.com/ROSES2025 and will appear on SARA's ROSES blog at: https://science.nasa.gov/researchers/solicitations/roses-2025/
Questions concerning D.8 HWO-ICA may be directed to Megan Ansdell at Megan.C.Ansdell@nasa.gov.
