What is the advantage of a satellite which passes over the poles orbiting the earth several times a day?

A polar orbit would allow a satellite to view any point on the Earth's surface from (nearly) directly overhead. The times for a given location would depend on the altitude and the speed of the orbit. The advantages are a minimal angle to the specific point below the satellite's path, which would benefit direct obsevation (as with military "spy satellites"). Among the disadvantages is increased fuel cost to reach the orbit, and increased shielding in some orbits due to the polar radiation belts around the Earth.

What does the word flyby mean?
In spaceflight jargon it means when a spacecraft or satellite passes close enough to an object in space (typically a celestial body, such as a planet) to gather scientific data without orbiting or landing on the object.
Why does the satellite suddenly stop being visible?
Possibly because it passes into Earth's shadow, though without more detail on exactly what satellite it's hard to be certain.
Why does the international space station look like a star?
What you see is the sun's light being reflected off it. This is the same for any satellite. As it passes it first starts to reflect more light at you so it gets brighter, and then it starts to reflect less light and slowly appears to fade away. It doesn't have any flashing lights, which is how you know it is a satellite and not a plane. It is the largest man made object orbiting us, so it is the brightest satellite. You can see other satellites in the same way, brightening up and then fading away, but as they are smaller, they reflect less light back and don't look as bright.
What are the 3 main stages in exploring a planet?
The three main stages in exploring a planet are: 1. send out a spacecraft that passes one or more bodies in space without orbiting them. 2. study a planet over a long period of time. and finally, 3. land instruments on a planet or to send instruments through its atmosphere.
Why does mars occasionally seem to go backwards in the sky?
Mars seems to orbit backwards because the Earth is orbiting at a faster rate so when Earth passes Mars it seems to orbit backwards.
What satellite is orbiting mercury?
Mercury has no known moons (or natural satellites) and has no manmade satellites orbiting it either. It was visited in the 1970s buy a man made probe called mariner 10, which made three passes to observe and map it's surface.

Which Satellite has an orbit which passes the equator?
All satellites pass the equator. Twice every orbit.

What is the difference between a satellite and a probe regarding where they travel in space?
A satellite is a craft in orbit around another body. A probe either passes by another body or goes to that body and lands (an sometimes returns).

Why are polar satellites called Detective satellite?
A satellite in a polar orbit orbits from north to south. As the earth turns, it passes over all the surface area of the earth. Therefore, polar orbits are ideal for detecting things on the planet's surface.

What city is autobahn in?
It passes through several cities. It is located in the country of Germany.

Can you buy several passes at a time on Howrse?
Absolutely. Hover your cursor/mouse over 'Profile' in the navigation bar and then choose 'My Passes'. From there, you can choose your country, how many passes you would like to buy, and how you would like to pay.
