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 Planetary Science Division plans that Habitable Worlds will not be solicited next year in ROSES-2021. It is still solicited this year and it is anticipated that it will be solicited every year after 2021. The due dates for this year remain unchanged: Step-1 proposals are due 11/17/2020 and Step-2 proposals are due 01/15/2021.


On or about July 6, 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 and will appear on SARA’s ROSES blog at:
