Explanation:
Above is one of the closest pictures yet obtained of
Saturn's ice-spewing moon Enceladus.
The image
was taken from about 1,700 kilometers up as the
robotic
Cassini spacecraft zoomed by the
fractured ice ball last week.
Features the size of a
bus
are resolvable in this highly detailed image taken of
Enceladus'
active tiger stripe region.
Very different from most other moons and planets,
grooves and hills
dot an alien moonscape devoid of
craters.
Space pioneers might wonder where, on such a highly textured surface, a future probe might land in search of freshly deposited ice,
subsurface seas, or even indicators of
life.
Although appearing dark in the above contrast-enhanced image, the surface of
Enceladus is covered with some of the brightest ice in the entire Solar System, reflecting about 99 percent of the light it receives.
To help better understand this
enigmatic world, Cassini is scheduled to
swoop by Enceladus at least five more times.
