Artificial Satellites

Artificial Satellites are objects launched from earth to orbit earth or other planets. Satellites are used for communication, remote sensing, weather forecasting, and other purposes. This category is for questions about satellites in general or specific satellites.

How do you place a satellite in earth orbit around sun?

It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun

What is an equatorial satellite?

A satellite in an equatorial orbit flies along the plane of the Earth's equator. If an orbit does not lie at an equatorial orbit, then it will not remain at a fixed state.

How accurate is satellite navigation compared to gps?

Satellite Navigation is just as accurate as GPS, having a 1-10 meter buffer zone. Both use a similar system, having satellites in orbit to triangulate a position. Satellite Navigation, better known as GLONASS, is used mostly by the Soviet Union while GPS, is use worldwide and the widest used system.

How can space satellite help the people on earth?

Without the space shuttle and space exploration in general, PC's, Microchips, PDA'S and all sorts of electronic, Hospital, Meterology and astrology equipment and/or techniques may not exist now

Can you see satellites in the mesosphere?

If your lucky.

Yes you can see them but it would be pretty hard to see. because of all the gasses and because of how far away you are and its hard anyways to see curtain things with the naked eye.

What is the oldest rocket?

The oldest rockets could have been made in China many years ago, as they invented gunpowder and fireworks.

What is the Canadian space agency's first satellite called?

Canada's first satellite was Alouette 1, a scientific satellite designed and built by the Defence and Research Telecommunications Establishment (a division of the Defence Research Board).

The functions of these organizations were later absorbed into the National Research Council, which the Canadian Space Agency was created from.

What day did Laika die in sputnik 2?

Laika the space dog, of Sputnik II died November 3, 1957, most likely due to overheating as a result of a malfunctioning heater in her capsule.

A satellite is projected vertically from an Earth station at what height above the Earth's surface will the force of Earth's gravity on the satellite be only half its value at the earth station?

To answer this question we need to know either the height of the Earth station above the Earth or the gravitational acceleration of gravity present at the Earth station initially.

Solving without these values:

(1/2)Gm/R2 = Gm/r2

where
G is the Gravitational Constant
m is the mass of the Earth
R is the radius of the Earth Station from the center of the Earth.
r is the radius of the satellite where gr=1/2ge

2R2 = r2

SQRT(2)R=r

What is the power source for a landsat satellite?

The power source for a Landsat satellite are four solar panels. Each solar panel was 2.3 meters by 1.5 meters.

How does a Landsat satellite differentiate between objects on Earth's surface?

Features on Earth radiate warmth at different frequencies, which show up as different colors on Landsat images.

What does the Sputnik Skull in Halo 2 do?

Its not on Nintendo ds and sputnik makes your melee attacks better and your grenades more powerful so you can do higher grenade jumps, It alters things mass.

What is the name of the person who launched the first satellite?

The Russians launched the first successful satellite. The leader of the project was lead by Sergey Pavlovich Korolyov as head Soviet rocket engineer.

What is the number of man-made satellites?

about 18,000 man made sattelites are orbiting the earth!

How much does it cost to build a satellite?

The total cost of building and launching a commercial satellite is approximately $200,000,000 to $600,000,000 according to Telenor Satellite Broadcasting. Their site has a lot of further information and can be found here: http://www.telenorsbc.com/templates/Page.aspx?id=410

200 million dollars

Camera used in satellite's?

Satellites are equipped with specialized cameras called imaging sensors or payloads that capture images of Earth from space. These cameras are designed to withstand the harsh conditions of space and are programmed to capture specific wavelengths of light to create detailed images of Earth's surface for various applications such as weather forecasting, agriculture monitoring, and urban planning.

Was the first thing in space a soviet satellite or a sputnik 1?

The first artificial satellite to orbit the Earth was a Soviet satellite named Sputnik I. It was launched by the USSR on October 4, 1957, followed by Sputnik 2 in November.

What is the difference between zero momentum and momentum bias spacecraft?

When the spacecraft is an equilibrium state, if the spacecraft has a momentum for specific axis, then the control of spacecraft is designed to momentum bias method. if else, it is called a zero momentum spacecraft. Zero momentum spacecraft: a spacecraft has four reaction wheel which is installed to pyramid configuration. if1st and 3rd reaction wheel is running to a 500 rpm and 2nd and 4th reaction wheel is running to a 500 rpm, them totoal net momentum is a zero.

Is Jupiter a luminous or non luminous planet?

Jupiter is not luminous in that it emits light, it reflects the Suns light so that it is visible to us on Earth. See also Albedo.
