it carries the the satellite over the earths north and south poles
The polar orbit so that it can measure cold and hot points around the entire earth :)
it is too cold and there is no power lines to get signal
i think because of the Earth's elliptical orbit, less sunlight reaches these places at the aphelion. =)
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
Quoting Wikipedia: The spacecraft was placed in a 525 km (326 mi), circular, polar, sun-synchronous orbit for its 10 month mission, during which it has taken 1.5 million images, one every 11 seconds.
polar
a polar orbit is not a type of geosyhchronous orbit.
Yes, but.... it would take a LOT of fuel to do! For practical purposes, the answer is no. No spacecraft built can carry enough fuel to significantly change its orbit.
Polar orbit
From a polar orbit, a satellite can observe over time anypoint on the globe from directly above it.
A polar orbit or high-inclination orbit. In polar orbit, the satellite passes over the world from pole to pole, while the Earth spins beneath it. Each orbit would cover a different area.
It will be able to record information to be more reliable and will be able to record results accurately at that time of day.
A satellite in polar orbit passes over the poles.A geosynchronous orbit follows the equator and at such an altitude its orbital period is one day long and remains in the same position relative to the ground.
Circum polar satellites.
A synchronous polar orbit satallite crosses the equator at the same time each day while the sun synchronous polar satellite appears in the sky at the same time every few days. the sun synchronous allow for greater temporal and spatial monitoring under same conditions and also have finer resolution as the polar synchronous imagery is at the continental scale.

As many times as necessary in order to get the ground map. I am no expert but one orbit from north to south (since this is polar) must depend on the impulse provided by the final kick to put it into polar orbit. TLDR is varies (I believe this is referred to as it's period) try examining various polar sats on file at wiki to see if this is correct. I to would like to know!
