Jupiter icy moon orbiter
NASA is planning an ambitious mission to orbit the three planet-sized moons of Jupiter, namely, Callisto, Ganymede and Europa. These moons may have vast oceans beneath their icy surfaces. The mission, known as the Jupiter Icy Moons Orbiter, would orbit each of these moons for detailed examination of their constituents, history and ability to sustain life.
Why these moons?
Let us see when NASA proposes to launch this spacecraft and its objectives.
