“Europa Clipper, the biggest interplanetary spacecraft that NASA has ever built, lifted off from the Kennedy Space Center in Florida early Monday afternoon.

The mission will tackle one of biology’s core questions: Can life exist anywhere else in our solar system?

The spacecraft’s destination is Europa, a moon of Jupiter, where water sloshes beneath a shell of ice that could be more than 10 miles thick. Such ocean worlds are fairly common in the outer solar system. That has created speculation: Could there be life swimming in any of those oceans?

For now, the answer is an intriguing maybe.

The $5.2 billion Europa Clipper mission is the first by NASA devoted to filling in the blanks to the question of habitability on these ocean worlds.”
