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 satellite communication is different from communication relay?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers.
For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.
Sputnik was the first spacecraft put into orbit, and was done by the Russians during the "space race".
It was important to America because we were in competition with the Russians and wanted to get there first.
How many satellites does the asteroid belt have?
the Asteroid belt has no satelites all the asteroids that make up the belt is another asteroids satelite so there would be thousands of satelites

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
The first artificial satellite to successfully achieve Earth orbit was Sputnik-I, launched
from the USSR in early October of 1957. It was visible from Earth with the naked eye,
if you knew where and when to look for it.
The world was buzzing with the news, and local newspapers published the time and direction
to see it. About two weeks after the launch, I got up at 4:00 in the morning, rode my bicycle
down to the big open field adjacent to the local Triple-A team's ballpark, swung my eyes
around to the designated place at the designated time, and was treated to a free show
by Sputnik-I that must have lasted at least three minutes. It was my 17th birthday.
Why does a geosynchronous satellite not trace a path over the surface of Earth?
A geostationary orbit achieved by being in a location where the satellite's orbital period is 24 hours. This means the satellite is about 36,000 km (22,000 miles) above the Earth's surface. All orbits must therefore be over the equator. Every orbit around the earth looks like a circular (or elliptical) ring whose center (or one foci) is at the center of gravity of the Earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the Earth's center and the whole orbit is flat like a disk. On various NASA maps this makes the orbit look like a sinewave, but on a globe it stays a flat circle (or ellipse). On "Star Trek" I have seen errors a number of times on "Geostationary orbit over the North Pole", well you can't do that. Likewise, a "Lunar-stationary orbit" is impossible for a spacecraft, since Earth itself is already IN THE STATIONARY ORBIT POSITION! Remember that a geostationary orbit looks like it is always over the same spot on the Earth (or other body). If you were on the Moon, the Earth would be in the same position in the sky at all times.
Do artificial satellites travel around the moon?
We have used artificial satellites in order to take pictures and study the moon and they did travel around it.
When does a satellite have the greatest acceleration?
When it is closest to the planet.
One of the components of the acceleration, the normal acceleration, is equal to v2/r, where v is the satellite's speed and r is the radius of the current orbit followed by the satellite. So, the smaller the radius, the higher the acceleration.
How did the Soviet launch of Sputnik affect science and technology in the United States?
I believe that the only technology we improved on as a result of sputnik is in image editing. sputnik started the great space race, an unspoken competition between the us and russia. eventually leading to the us moon landing. but a lot of people have said this victory of the space race was a hoax. try looking up some info on video about the moon hoax. it's actually pretty convincing.
It gave space technology an enormous boost, as it came to the forefront due to the US Government's desire to not fall behind the Soviet advancements. Sputnik caught them somewhat unprepared, and for a time, nothing was spared in order to establish superiority in the race. ______ Most of the USSR's space endeavours were launched from Baikonur in central Kazakhstan.
What best describes he soviet satellite sputnik?
The first man made object to be launched into orbit successfully.
According to http://en.allexperts.com/q/Astronomy-1360/Observing-Satellite-Naked-eyes.htm, satellites shine because they reflect sunlight (presumably because they are made of shiny, reflective metal). They orbit high above the earth, so for 2-3 hours after sunset and before sunrise, the sun doesn't shine on the part of Earth you are standing on, but it still hits the satellite. This is when you are most likely to see a satellite.
When were satellites invented?
In 1957, the Soviet Union launched Sputnik, which was the first man-made satellite.
The first satellite was Sputnik 1, launched on October 4, 1957.
Sputnik is the first publicly recognized artificial satellite, but there are large rumors (but obviously no confirmation for this is classified information) that the U.S. launched a modified V-2 rocket in 1948.
in 1957
Sputnik 1 was the first satellite. It was launched by the former Soviet Union in 1957.
The first satellite put into orbit was a Russian satellite called sputnik. It was put into orbit on 10/4/1957.
The pictures obtained from weather satellites show cover and areas of?
The pictures obtained from weather satellites show cloud cover and areas of precipitation
What are Communications satellites?
Communication satellites receive signals from antennae on the Earth's surface, or from other satellites, amplify the signals, and beam them back to Earth. Because they are hundreds or thousands of miles up, their signals can cover a larger area than most radio or television signals broadcast on the surface, because of the Earth's curvature. (Radio waves don't go around corners well.)
Some communications satellites are in quite low orbits, around 150 miles high. Others are in "geostationary" orbits at about 22,500 miles, where their rotation around the Earth is the same speed as the Earth's rotation, so that they stay above a particular spot all the time. Most broadcast satellites for TV, phone service and satellite radio are geostationary.
