Because instead of close up high resolution images our polar orbiting satellites provide much more frequent coverage twice daily over the whole planet in order to understand global weather patterns.
Satellites monitor ocean temperatures and prevailing currents.
For the closer satellites engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere.
In the context of spaceflight a satellite is an object that has been intentionally placed into orbit these objects are called artificial satellites to distinguish them from natural satellites such as earth s moon.
Satellites differ greatly in the level of detail they can see.
Imaging satellites can measure the changing sizes of glaciers which is difficult to do from the ground due to the remoteness and darkness of the polar regions.
