The Habitable Worlds Observatory Precursor Science Investigations (HWO-PSI) program element D.8 under ROSES-25 aims to develop the scientific groundwork necessary to mitigate risks for a future HWO mission. This update corrects an oversight in the original announcement, adding the Open Science and Data Management Plan to Table D.8-1 "Parts of the Anonymized Technical Proposal" in Section 3.4. The correction is marked in bold for clarity.
The program maintains its original deadlines: Notices of Intent (NOIs) are due by September 10, 2026, with proposals due on October 26, 2026. Proposals for this program will undergo evaluation through dual anonymous peer review. Any inquiries regarding D.8 HWO-PSI should be directed to Megan Ansdell at Megan.C.Ansdell@nasa.gov.
