What Can Satellites Do
A satellite is a moon planet or machine that orbits a planet or star.
What can satellites do. Like every other machine satellites do not last. Data acquired by satellite borne radars were able to show sea levels have been rising by three mm a year over the last decade. 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. Why can t noaa s satellites see someone s house.
Further satellites are instead sent even farther away from earth. On 4 october 1957 the soviet union launched the world s first artificial satellite sputnik 1 since then about 8 900 satellites from more than 40 countries have been launched. 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.
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. The soviet union launched the first artificial satellite sputnik 1 on october 4 1957. 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. Artificial satellites can be sent to orbit other planets too.
