Can we control the variable speeds and where a satelite travels in space from earth?

A satellite's orbital speed is determined by its altitude. Changing speeds changes altitude. Speed it up and it climbs higher, slow it down and it drops lower.





Low earth orbit objects such as the shuttle and ISS orbit in the 100-200 mile range above the earth. As stated previously, they orbit once about every 90 minutes. Geostationary satellites for use in TV broadcasts and other telecommunications applications orbit some 22,000 miles above the earth. At that altitude, their orbital velocity is the same as the earth's rotational velocity, allowing them to remain in the same relative position all the time. An onboard fuel supply allows the maneuvering jets to make small ';station keeping'; adjustments when necessary.Can we control the variable speeds and where a satelite travels in space from earth?
noCan we control the variable speeds and where a satelite travels in space from earth?
No, not unless the satellite Had some kind of population unit on board via air burst, or a blast of fuel. I can only think of one satellite that had this feature it was called deep impact it was to determine what asteroid's are made of that is the only transmitting satellite that had a motor on board, and it is just floating around out there now out of fuel. But as for the standard orbital satellite, no There held in place by harnessing the gravitational pull of the the earth at what we call standard orbit. It will make one lap around the earth every 90 min. with no variable speed, it remains constant the minute it dose not hold it set seed it will fall to earth.
No. Technically speaking a satellite is an object without any onboard motors for changing its direction/speed.





Any object travelling in space requires a ';push'; of some sort, which typically comes in the form of a burst of fuel fired in the opposite direction to which acceleration is desired. This obeys Newton's 3rd law (for every action there is an equal and opposite reaction) meaning that the object is propelled forwards (or backwards, or sideways etc).
