Mapping of Decadal Survey Themes to Roadmaps to Ocean Worlds Objectives

		Relevant ocean worlds objectives
Decadal survey cross-cutting science theme (Chapter 3)
Planetary habitats	Beyond the Earth, are there contemporary habitats elsewhere in the Solar System with necessary conditions, organic matter, water, energy, and nutrients to sustain life, and do organisms live there now?	I. A, B II. A, B III. A, B IV. A, B
Decadal Survey satellites science theme (Chapter 8)
What are the processes that result in habitable environments?	Where are subsurface bodies of liquid water located, and what are their characteristics and histories?	I. A, B II. A
	What are the sources, sinks, and evolution of organic material?	I. C II. B III. B
	What energy sources are available to sustain life?	II. B III. A
	Is there evidence for life on the satellites?	IV. A, B
How did the satellites of the outer Solar System form and evolve?	How are satellite thermal and orbital evolution and internal structure related?	I. A, C III. A
	What is the diversity of geological activity and how has it changed over time?	I. B
What processes control the present-day behavior of these bodies?	How do endogenic processes shape the satellites' surfaces and influence their interiors?	I. A, B
	What processes control the chemistry and dynamics of satellite atmospheres?	I. B II. B
	How do exogenic processes modify these bodies?	III. B
