Amendment 61: Habitable Worlds Change in Scope.

The goal of the Habitable Worlds program is to use knowledge of the history of the Earth and the life upon it as a guide for determining the processes and conditions that create and maintain habitable environments and to search for ancient and contemporary habitable environments and explore the possibility of extant life beyond the Earth.

The scope of this program element has been updated to include transient environments. Please refer to the bullet list of target bodies in Section 1. The main point of contact has also changed, see below. The proposal due dates remain unchanged: Step-1 proposals are due 11/17/2020 and Step-2 proposals are due 01/15/2021.

On or about October 19, 2020, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2020" (NNH20ZDA001N) will be posted on the NASA research opportunity homepage at http://solicitation.nasaprs.com/ROSES2020
