NOTICE: This program element no longer uses the two-step proposal submission process common in Appendix C. Instead, a Notice of Intent (NOI) is requested in place of a Step-1 proposal. NOI and proposal due dates are given in Tables 2 and 3 of ROSES.

Proposals to this program element are subject to a relevance requirement in addition to and that supersedes those detailed in the ROSES Summary of Solicitation.

Important Dates
Notice of Intent (NOI) Due Date: April 16, 2018
Proposal Due Date: May 24, 2018

The goal of NASA’s Exobiology Program is to understand the origin, evolution, distribution, and future of life in the Universe. Research is centered on the origin and early evolution of life, the potential of life to adapt to different environments, and the implications for life elsewhere. This research is conducted in the context of NASA’s ongoing exploration of our stellar neighborhood and the identification of biosignatures for in situ and remote sensing applications. For further information on the science scope of Astrobiology — within which exobiology is located— please refer to the Astrobiology Strategy, which can be found on the Astrobiology web page at: https://astrobiology.nasa.gov/research/astrobiology-at-nasa/astrobiology-strategy/.

Proposals are sought for new projects within the scope of the Astrobiology program. Proposals submitted in response to this program element should be for new work that is not currently supported by the program or for investigations that would extend to their next logical phase those tasks that have been funded in the Astrobiology program, but whose periods of performance expired in the last year or are expiring in the first half of this year.

Program Exclusions
Research aimed at investigating the habitability of planetary bodies in our Solar System other than Earth or in other planetary systems should be submitted to the Habitable Worlds program (E.4).

Proposals focused on the formation and stability of habitable planets and the formation of complex organic molecules in space and their delivery to planetary surfaces should be submitted to the Emerging Worlds program (C.2).

Proposals aimed at the identification and characterization of radio signals from extrasolar planets that may harbor intelligent life are not solicited at this time.
