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 is Eclipse effect in satellite communication?
The eclipse effect in satellite communication occurs when the satellite passes into the shadow of the Earth, causing a temporary loss of communication signal. This happens during solar eclipses or when the satellite is behind the Earth in its orbit. To mitigate the impact, satellite operators can use battery power or pointing strategies to maintain connectivity during these periods.
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.
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.
What orbit would allow a satellite to see all parts of the globe?
A geostationary orbit would allow a satellite to see all parts of the globe as it orbits the Earth at the same speed that the Earth rotates. This means the satellite remains fixed above the same point on the equator, providing continuous coverage of that area.
Why does the satellite suddenly stop being visible?
A satellite can stop being visible due to factors such as entering the Earth's shadow, changing its orbit, or switching off its reflective surfaces making it harder to see from the ground. Additionally, atmospheric conditions, like clouds or light pollution, can also obstruct visibility of satellites.
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.
Why does the satellite suddenly being visible?
Possibly because it passes into Earth's shadow, though without more detail on exactly what satellite it's hard to be certain.
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).
What city is autobahn in?
It passes through several cities. It is located in the country of Germany.
Meaning of tle?
TLE stands for Two-Line Element Set, which is a data format used by satellites to describe their orbits. It includes information such as the satellite's position, velocity, and time parameters. TLE data is commonly used by satellite trackers and ground stations for predicting satellite passes and orbital analysis.
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.
Is the orbit for a tv satellite called a polar orbit?
A polar orbit (as opposed to an equatorial orbit) passes over the poles, north and south. A low orbit is relatively close to the Earth (or other object being orbited), it might be a few hundred miles up.
Where can one purchase passes for Eurail?
If you are interested in purchasing passes for the Eurail, then you will find several websites available. The Eurail official website offers online purchasing options.
What is eclipsing binary?
Two stars orbiting each other so that one regularly passes in front of the other blocking out some or all of light of the hidden star. See related link for an animation.
