The NASA Outer Planets Assessment Group (OPAG) Roadmaps to Ocean Worlds (ROW) group has published a guide with recommendations on how to develop an initiative for the research of Ocean Worlds. This includes confirmed ocean worlds Enceladus, Titan, and Europa and candidate worlds such as Triton. Development of the roadmap began in 2016.

The overarching goal of an Ocean Worlds exploration program as defined by ROW is to “identify ocean worlds, characterize their oceans, evaluate their habitability, search for life, and ultimately understand any life we find.”

The NASA Roadmap to Ocean Worlds is published in Astrobiology.
