Artificial Satellites

No. A geostationary satellite appears to be stationary in the sky, which means not moving. This is a big part of the reason why it is referred to as a geo'stationary' satellite.

A satellite is a body orbiting another like a planet or moon. A natural satelite is not man-made. The moon and other bodies were called this before the artificial, or man-made satellites were ever made like the ISS.

Sputnik was the first artificial satellite ever launched into space. Because it was a Russian accomplishment, the United States immediately hurried to catch up with them. This competition was a major characteristic of the Cold War.

Sputnik was a family name for a series of satellites, most of which burned up during reentry after some time in orbit.

with calls themselves, nothing. however all current cell phones have a GPS receiver that picks up and decodes the signals from GPS satellites so their position can be accurately determined for emergency 911 calls.

Ku band, (Transmit frequency 13.75 to 14.50 GHz, Receive frequency 10.70 to 12.75 GHz dependant on which region of the earth you live in) is used rather than C band (4 to 6 GHz) because the higher frequency allows for broader transmit and receive bandwidths, so more data, computer traffic, movies, etc can be sent. The signal power lost in transmitting from earth to the satellite and back to earth again varies with frequency, but not as a simple linear sloping line increasing with frequency way, it has peaks and troughs. This is because at some frequencies Oxygen and Water absorb much more power and it is difficult to generate enough power to pass a strong signal through the atmosphere, so those frequencies are avoided. Ku band uses a part of the frequency spectrum with a lower atmospheric loss between earth and space, so relatively less microwave power is needed to efficiently transmit to and from the satellite.

Launched in 1996, and bought by Microsoft in 1997, Hotmail was one of the earliest free Webmail services and became the first e-mail address for millions of people, perhaps rivaled only by AOL Mail. But what was once new and exciting in the late 1990s became stagnant and less innovative by the early 2000s. Around 2004, Google‰Ûªs Gmail was the hot new e-mail service, while Hotmail appeared dated. That lack of trendiness, however, did not cause Hotmail to bleed users. In fact, it was only recently that Gmail finally surpassed Hotmail, reaching 425 million active users in June, while Hotmail‰Ûªs last reported user base hovered around 360 million.

To simply find out more about the Martian planet. Before the Martian probes were launched, much was of course known about Mars- that it had not supported life for hundreds of thousands of years, that the so-called 'canals' were a geographical feature and not artificially made, and so on.

But Scientists from Earth were curious- warranted, the 'canals' were not made by intelligent life, and all evidence supported the theory that Mars is a dead planet. BUT- had it once, maybe, held water? Nobody for a minute imagined that life- even vegetation- existed on Mars, but PERHAPS, it might at one point in the past have had water on it, which MAY have given rise to primitive lichens, and maybe bacterial forms of life. Probes (both orbital and landers) can give the answers to these questions.

And this is indeed what they are currently finding out- the Mars Orbiter suggests that there may indeed be a residue of underground water left on Mars, that appears at some seasons of the year. If any life- even at microscopic level- ever existed there, they would be long dead by now, but their fossilised remains MIGHT exist in ancient rocks, which would indicate that eons ago, Mars may have been closer to the Sun than it is now, which would allow organic life to develop.

The other reason that probes were sent there, was simply to find out what it looked like. Nobody knew what Mars looked like before 1969, when the first probe succesfully landed- and even then, it only transmitted pictures for about 15 seconds. The first truly succesful probe was Mariner 1 in 1976, which broadcast pictures of the Martian surface- it's true that she landed on the South-East of the planet, which is not the best place to go, so all she got was a view of a red desert covered in rocks. Other probes since then have taken pictures of a more interesting geography, with hills, small valleys and variable soil, as well as analysing the content of the atmopshere, but even so the fact remains that Mars cannot, and has not supported, life for many Millenia.

Maybe in Centuries to come, humankind will be able to travel to Mars, and then much further along, even modify it's atmosphere so that people can breathe normally on it without the need of space-suits. But this is a long way off- such things will not happen in the lifetime of anyone alive today! It's quite possible that this will happen ONE day, but not for a VERY long time.

it is too cold and there is no power lines to get signal

because of the gravity in our solar system. The sun keeps us (the earth) in its gravity. And we keep the satellite in our gravity. And it works like stone in thread and if we rotate it then stone will be at the other end of thread and will keep surrounding you.

A town designed to house the overspill population of a major city, but located well beyond the limits of that city, and operating as a discrete, self-contained entity.

Town, self-contained and limited in size, built in the vicinity of a large town or city to house and employ those who would otherwise create a demand for expansion of the existing settlement, but dependent on the parent-city to a certain extent for population and major services.

Artificial satellites are outside of the atmosphere, and therefore do not experience any friction with it. They are in the vacuum of space, where nothing will slow them down by friction. Since they have enough velocity to keep from dropping below the atmosphere of Earth, they are in a stable orbit, the same way the Moon is. However, they do not move at perfectly uniform speed. Like all satellites of all bodies, they move more speedily when they are closer to earth and less speedily when they are farther away from Earth. Their orbits can be corrected by changing their orbital velocity, but it is nearly impossible to get a perfectly circular orbit. Being in a close to circular orbit, they remain nearly uniform in velocity.

Yes, satellite images based on data obtained by land sat satellites.

ROSAT is a German satellite launched in 1990. It was used for research on black holes and neutron stars. It was supposed to be in space for 18 months, but since it was successful it stayed there for 8 more years. In 1999 communication of ROSAT satellite with Earth was lost. Scientists predict that it will hit the Earth sometimes between October 21 and October 24, 2011. Parts of the satellite will burn up during the re-entry in atmosphere, but at least 30 fragments, weighing 1.87 tons could crush into Earth with a speed up to 280 mph.

The acronym INSAT means Indian National Satellite in the Geo Stationary Orbit. The GSO satellites are useful for communication and weather forecasting . They carry C , Extended C and Ku Band Transponders (16 Numbers ) for TVRO and DBS schemes. The satellite design, testing, fabrication and assembly are the joint venture of Technical persons of ISRO and any individual.

Tiros l because, it sent back information to earth of aproaching storms

A space station is a satellite designed to allow humans to live in outer space.

Sputnik wasn't a space shuttle, but a series of early satellites launched by the then Soviet Union. Being one-shot items, they were retired as soon as their missions were over.

how to work HPA

In order to appear motionless in the sky, the satellite must be in an orbit that is

-- circular

-- over the equator

-- 22,400 miles above the surface

Gallium, Silicon and Aluminum

i dont freaking know

The Explorer 1 was launched on January 31,1958 one year after the Sputnik 1,and Sputnik 11

answer or nawh?
