How does an artificial satellite stay in orbit once correctly placed above Mars?

They usually get their energy from the Sun, but they may also have a nuclear reactor. That's how they get their energy; how they work in detail would depend on what they are supposed to do. There are satellites for many different purposes.

∙ 14y agoThat's simply called "artificial satellite" or just "satellite".
Artificial is used to distinguish man made satellites from earths natural satellite, the moon.
The space lab is an artificial satellite. GPS satellites are artificial. There are also many communications satellites.

∙ 10y agoThere's Low earth orbit, medium and high earth orbits.
Hubble, Mir (was) and the International space station are in the low earth orbits (among others including the polar orbiting satellites) These are between 212 and 1200 miles up.
Further out is the Medium earth orbit band, these satellites take longer to orbit the earth due to their increasing distance. At around 12000-13000 miles up are the GPS satellites, this is where the orbits are such that the satellites orbit the earth once every 12 hours (semi synchronous).
At 22,236 miles up is the boundary between medium and high earth orbit. Here, there are the geosynchronous satellites. It is at this height that the satellites take exactly 24 hours to orbit the earth, so they therefore can hold an 'apparent' position over one spot of the earth as it rotates. This makes easy tracking with a permanently fixed dish (such as a satellite TV dish).
Pretty much everywhere above the atmosphere. For example, the space station is about 200 miles above the surface of the Earth, and orbits every 90 minutes or so. Geosynchronous satellites are in a ring about 26,199 miles up. The GPS satellites are closer and appear to orbit the Earth once a day, any satellite farther than the geosynchronous distance seem to lag behind us. The paths the satellites are in depend entirely on their mission: for example we have some circumpolar satellites that cover both poles every orbit, whereas the geosynchronous ones are basically around the equator. Some other considerations are space debris (the Van Allen belts are pretty cluttered with high energy chunks that have taken out satellites very quickly), and the atmospheric drag tends to hinder them at about the Karman Line (100 km or so).

∙ 10y agoPlease note that keeping in orbit around Earth requires no continuous energy supply. If a satellite has sufficient speed, it will continue orbiting the Earth (or some other object) on its own, for a long, long time.

∙ 16y agomars's gavitational pull keeps it in track because it is so much larger than the satellite

The gravitational force and the Satellite's velocity (speed at which it would travel in a straight line) is balanced.

What are two artificial satellites that orbit New Zealand?
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.
What is the height of sewer air pipes above ground?
The Fresh air inlet is placed 6" above grade and a vent terminal is placed 2 feet above the roof surface UNLESS it is a promenade deck then the VT must be 7 ft above the surface and should be a min of 4" to prevent hoarfrost
If a satellite orbiting just above the surface of the Earth orbits in about 1.5 hours then at about how many Earth radii from the Earth's center must a satellite orbit to have a period of 24 hours?
You can use Kepler's Third Law to calculate this.
A satellite is 200 miles above the earth It has a mass of 150 kg If the mass of the satellite were tripled?
You don't really have a question here. If the satellite is in orbit, the mass is essentially irrelevant; it wouldn't change the speed of the orbit or the altitude. A larger satellite mass WOULD HAVE required more fuel and more energy to LAUNCH it, but once in orbit, it will stay there. The only exception would be an exceptionally large, light satellite. There is still some minuscule traces of atmosphere at 200 miles, and a large, light satellite would be slowed by air friction much more than a small dense satellite would. This is what caused the "ECHO" satellite - essentially a silvered mylar balloon inflated in orbit as a primitive reflector comsat - to deorbit.
What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
How many miles above earth does DigitalGlobe's World View 3 WV3 artificial satellite sit to revolve around earth?
WorldView-3 satellite maintains an altitude of 617 kilometers. Launched on August 13, 2014, it is a commercial Earth observation satellite owned by DigitalGlobe, a private company.

What are two artificial satellites that orbit New Zealand?
Satellites cannot orbit one country. They may remain in geostationary orbit, but only at the equator. Therefore no satellite stays above only New Zealand.
Which atmosphere are satellites found in?
Low earth orbit (LEO) satellites are defined as any artificial object between 160 km and 2000 km altitude. Any satellite from 160 km to 690km are in the Thermosphere.Any satellite in the region between 690km to 10,000 kmaltitude are in the Exosphere.10,000 km is considered the very top of the atmosphere. Any satellites above this altitude is not considered in the atmosphere. Geostationary satellites for example are at an altitude of 35,786 km.
Can you give me a sentence using the word satellite?
the satellite was 1500 feet above the atmosphere of earth
Where is a satellite when it stays at the same point above earths surface?
That's a "geostationary" satellite. It's roughly 22,000 miles above the equator, in a circular orbit.
Where did Arctic Circle placed above or down?
above
Why do communication and weather satellites always appear at the same place in the sky?
That is because those satellites are in geostationary orbit, which ensures that they stay always above the same spot on the earth's surface. This is possible only if the satellite is placed in orbit at about 22,000 miles above sea level.
How satellite pictures of earth are made and transmitted?
Satellite pictures of Earth are taken by a camera mounted on a satellite in orbit, high above Earth's atmosphere. They are transmitted wirelessly over satellite signals, much like satellite TV.
How far above the earth is geostationary orbit?
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
