In Greek mythology, Oceanus or Okeanos was one of the Titans, the children of Uranus (Sky) and Gaia (Earth), and the god of the great river which encircled the entire world. He was the brother and husband of the Titaness Tethys, and by her was the father of the river gods and the Oceanids.
Read on WikipediaOceanus is a NASA/JPL orbiter mission concept proposed in 2017 for the New Frontiers mission #4, but it was not selected for development. If selected at some future opportunity, Oceanus would travel to Saturn's moon Titan to assess its habitability. Studying Titan would help understand the early Earth and exoplanets which orbit other stars. The mission is named after Oceanus, the Greek god of oceans.
