Explanation : This is what it would look like to fly over the surface of Jupiter's moon Ganymede. NASA's robot spacecraft Galileo recently approached only 6000 miles from this frozen ice-ball of a moon. The above image is a digital reconstruction from two images taken during this flyby. The blue color of the sky is artificial. Deep furrows cover Ganymede's surface , and several impact craters are also present. Galileo continues to orbit Jupiter and send back breathtaking photos of Ganymede , Io , Europa , Callisto , and, of course, Jupiter itself.
