  Natural Satellite - MSN Encarta
The motion of most of the solar system's natural satellites about their planets is direct: west to east, in the same direction as the rotation of their planets.
Several small satellites of the large outer planets, however, revolve in the retrograde direction: east to west, opposite the direction of the rotation of their planets.
These retrograde satellites tend to orbit far from their primaries and were probably captured by the planets' gravitational fields some time after the formation of the solar system.

 NASA - Artificial Satellites
A satellite remains in orbit because of a balance between the satellite's velocity (speed at which it would travel in a straight line) and the gravitational force between the satellite and Earth.
Scientists use Earth observing satellites to locate mineral deposits, to determine the location and size of freshwater supplies, to identify sources of pollution and study its effects, and to detect the spread of disease in crops and forests.
A satellite slows down due to occasional impact with air molecules in the upper atmosphere and the gentle pressure of the sun's energy.

 What Is a Satellite?   (Site not responding. Last check: 2007-11-02)
When the satellite reaches its orbit, a motor points it in the right direction and its antennas and solar panels deploy—that is, they unfold from their traveling position and spread out so the satellite can start sending and receiving signals.
Satellites in orbit can send messages to a special receiver carried by someone on a ship in the ocean or in a truck in the desert, telling that person exactly where he or she is.
Satellites can't be allowed to jiggle or wander, because if a satellite is not exactly where it belongs, pointed at exactly the right place on the earth, the television program or the telephone call it transmits to you will be interrupted.

Bubbles are naturally spherical - natural tendency for that shape (teacher note - this is because of surface tension).
Natural satellites are spherical too, but for a different physical reason - gravity will produce sphere shaped bodies in space - this is also a natural tendency.

 Hal Shelton Revisited - Satellite Images
It is a rare map that uses a satellite image as a raster base in conjunction with other map information, such as labels, lines, area tones, and point symbols.
The lack of satellite images used as cartographic backdrops, in the same manner as shaded relief or hypsometric tints, has a simple explanation: they are not maps.
A satellite image distilled into a land cover classification of, for instance, a dozen categories is merely the raster equivalent of the polygons etched into zinc plates that guided Shelton’s painting.
