Artificial Satellites

This question refers to man made space satellites. Satellites can have multiple owners between national governments, private companies, and universities.

There are regular software that are designed to create maps for different games. Each game presumably has a software designed for handling this task.

One can purchase satellite dish service directly from the satellite company to which you are subscribing. There is a toll free number for the companies which you can phone and set up your purchase.

Google Earth and Google Maps provide interactive access to satellite imagery that are often less than 3 years old.

For special events or natural disasters (e.g. Haiti earthquake) Google has made new satellite imagery available in matter of days or weeks.

If you want more up-to-date imagery then you might want to check the imagery providers directly (e.g. GeoEye, DigitalGlobe, etc.).

Weather reports were not accurate. Long distance communication required cables and microwave relay towers. There was no GPS navigation systems. Land was mapped slowly and expensively.

yes

The closer to the Earth, the faster the orbit; this is basic math, as determined Johannes Kepler centuries ago. The higher the orbit, the slower the satellite goes.

IN 1947, science fiction writer Arthur C. Clarke wrote an article and a story based on the curious coincidence that if a satellite were placed in an equatorial orbit 23,000 miles (or 36,000 km) up, the satellite would orbit the Earth at precisely the speed that the Earth itself turns. The satellite would appear to be suspended, motionless, in the sky!

Since an Earth-based antenna would not need any rotors or pointing mechanisms to track an unmoving satellite, the antenna could be made larger - MUCH larger.

We now call that orbit "geo-synchronous", and that's where we park communications satellites, and TV satellites.

It didn't occur to Arthur Clarke to patent his invention; and because he did not, the satellite communications revolution proceeded unimpaired by patent lawsuits.

Satellites in low orbit are affected by drag from the very top layer of the atmosphere. This drag eventually slows them down, which brings them in contact with denser layers of atmosphere, which slows them down and brings them down even more. Eventually, they burn up by the heat from rushing real fast through the air.

GSLV-F06 was recently launched by India ( ISRO- Indian Space Research Organisation) but it failed and was destroyed.

Sputnik 1 was launched into Earth's orbit on 4 October 1957. It remained there for less than 3 months and collected atmospheric data. The satellite fell out of orbit on 4 January 1958. It burned up upon reentry into the Earth's atmosphere.

It depends one what satellite it is. Differents types of satellite orbit the Earth at different altitudes. In Low Earth Orbit satellites travel between 160km and 2000km above the Earth, in Medium Earth Orbit they travel between 2000km and 35000km above the Earh, and in Geostationary Orbit they travel above 160km and below 35000km around the Equator.

. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!

The dog, Laika, died due to temperature increase.

umm if my calculations are correct the period of a low earth orbit (LEO) is approximately 40000000000069 years. as extrapolated from Kepler's equation.

There are nine types of artificial satellites. Here is the list: Astronomical satellites, Biosatellites satellites, Communication satellites, Miniaturized Satellites, Navigational satellites, Reconnaissance satellites, Earth observation satellites, Space stations, and Weather satellites.

"Sputnik 1 burned up on January 4, 1958. It fell from orbit upon re-entering earth's atmosphere after traveling about 60 million km (37 million miles) and spending 3 months in orbit." That straight from Wikipedia. A link is provided.

Television service, weather prediction, global positioning system in my car.

There were in fact several Sputnik satellites, but I imagine you're asking about the very first.

Sputnik-1 spent 3 months in orbit before re-entering and burning up. It was launched on October 4 1957, and was destroyed on January 4 1958. So it's location today would be... nowhere. It's believed to have been destroyed entirely. There is one piece left of sputnik, http://en.wikipedia.org/wiki/Sputnik_1 This metal arming key is the last remaining piece of the first Sputnik satellite. It prevented contact between the batteries and the transmitter prior to launch. Currently on display at the National Air and Space Museum.

America was worried that Russia could start bombing them if they wanted. The fear of Russia being the first ones in space was amplified by the Cold War, and many Americans thought that by dominating space, the Russians would be able to launch any kind of attack they felt like at any time on the U.S. from space without any opposition, because the U.S. had no satellites in space. It started the space race, which was a period of time during which the United States rushed to get satellites up into space as well, to close the rift that had emerged between Russian and American space technology.

''''' James brown evented satilites in 1882 and remmberd one part of the satilie called he benjoey (ben-jov-ey) and mistakked the meandrea(mea-on-dra) then James brown got the satilite fixed and perfect.'''''

No Advantages.

Answer

All satellites are sent into space with a purpose in mind. It may be to register weather patterns on earth or have a built in telescope to see further into space. They may be sent to pick up signals roaming around in space. Many are of a military type and are used to spy on other countries.

We know that the centripetal force on an object is mv^2/r where m is the mass of the satellite, v is the tangential velocity, and r is the distance from the center. We also know the centripetal force is the force of gravity, which is GMm/(r^2), so we have v = Sqrt(GM/r) where G is the gravitational constant and M is the mass of the Earth. The distance from the satellite to the center of the circle is 42.25*10^6 + 6.4*10^6 = 48.65*10^6 m. We then get v = Sqrt(6.67*10^(-11)*5.97*10^24*10^(-6)/4.87) = Sqrt(8.2)*10^4 m/s = Sqrt(8.2)*10 km/s
