Amendment 18: Final Text and Due Dates for Interdisciplinary Consortia for Astrobiology Research.

A wide array of NASA Science Mission Directorate flight missions incorporate astrobiology goals and objectives. For this reason, with C.20 Interdisciplinary Consortia for Astrobiology Research (ICAR) solicits proposals responding to both the long-term goals and objectives identified in the Astrobiology Strategy and focused on ensuring that the NASA Astrobiology community is prepared to respond to the challenge of planning and implementing these missions. Accordingly, proposals that place emphasis on research that will help prepare for current or future flight programs directed at astrobiological targets are encouraged. Proposals must describe an interdisciplinary approach to a single compelling question in astrobiology, and address at least one aspect of the current Science Strategy.

ROSES-2022 Amendment 18 releases final text and due dates for C.20 ICAR. This program element uses a two-step proposal submission process in which team members may not be added after Step-1. 6-page Step-1 proposals are due September 15, 2022, and 25-page Step-2 proposals are due January 10, 2023.

On or about May 16 2022, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2022" (NNH22ZDA001N) will be posted on the NASA research opportunity homepage at
