The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is thought to possess a vast ocean of liquid salt water. For decades, scientists have wondered whether that ocean could harbor the right conditions for life, placing Europa near the top of the list of solar system bodies to explore.
Still vastly more “teraformable” than Mars due to the fact that it is protected (I think) by Jupiter’s magnetic field.
Definitely, I think they mean “to support life” as in “to support extraterrestrial life”.
