Artificial Satellites

Lots of ways. For example, the momentum of satellite + meteor before the impact, is the same after the impact.

The first satellite, Sputnik one, was launched on October 4, 1957 by the Soviet Union.

Its a centripetal force, whose origin/source is gravitation.

Satellites are made by metal and glue.

False. Only the so-called 'artificial' satellites are man-made. The 'natural' satellites didn't get that name because of the ingredients used to manufacture them. They are called 'natural' because they were created by Nature, not by man. Earth's Moon is an example of a natural satellite, not man-made. There are almost 100 more known examples elsewhere in the Solar System.

i really dont know sorry but other questions just type to me iand will answer it

The FCC Gov site has a great overview and learning resource for people to learn about satellites. Additionally, one could look on the NASA website which has a wealth of information, and a different perspective.

If he had used an ordinary mirror he would only get one reflection per revolution, and since the light travels so fast his motor speed would have to be impossibly high. So he put 8 mirrors on the spindle and the rotational speed then needed to be only 1/8 of that for a single mirror.

GSLV wont move with respective to earth

PSLV will be stationary with respective to sun, so it will meet a point on earth 7 times a week

what are the primary steps to make a satellite?

Jupiter's 4 major moons, known as the Galilean satellites, are named Io, Europa, Ganymede, and Callisto. Io is an orange moon with an abundance of volcanic activity most likely caused by Jupiter's magnetic field. Europa is a cold, frozen ice moon and is also the smallest of the four. Ganymede is the largest and also is thought to have oceans. Callisto is the outermost moon (of the 4) and is covered with craters.

Orbiting the Earth above the equator is true of geostationary weather satellites and they have infrared sensors to transmit images of the entire hemisphere continuously. All of those things are true except that while they are moving in orbit they appear motionless.

Both PSLV (Polar Satellite Launch Vehicle) and GSLV are (Geosynchronous Satellite Launch Vehicle) are launch Indian vehicles used to launch satellites into polar orbit and geosyncronous orbits respectively.

The PSLV can launch satellites into sun synchronous orbits i. e. in such a way that an object on that orbit passes over any given point of the Earth's surface at the same local solar time.

The GSLV launch satellites into geostationary orbit. Geostationary orbits cause a satellite to appear stationary with respect to a fixed point on the rotating Earth. That is, if you were standing directly below a geosyncronous satellite it would always be directly above you.

The PSLV is a four-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled and third solid and the final stage cryogenic liquid. It required parts obtained from Russia.

The GSLV is a three-stage launch vehicle with the first stage being solid-propelled, the second liquid-propelled and the final stage being cryogenically propelled. It was developed by India partly to free itself from dependence on Russia.

In order for a satellite to stay in space and not fall to earth, it has to move in orbit round the earth. Many satellites and the International Space Station are in low orbit and at that distance above the earth orbit the earth in a couple of hours or so. However, if the orbit is around 26000 miles up, then at that distance the time it takes for a satellite to freely orbit is exactly one day or 24 hours. This means that the satellite is always above the same spot on earth, as the earth also takes 24 hours to rotate. Thus, if we could see the satellite in the sky it would not move across the sky like the International Space Station but it would stay in the same place in the sky.

This means that they can be used for communication - when you telephone, say, from Europe to the USA then the signals are received by these satellites, amplified and relayed across the world to the receiver of the call. As the satellites are in the same place in the sky all the time, you can call at any time of the night or day. However, if the satellite moved across the sky in low orbit you would only be able to use it when it was in the sky - in other words you could only telephone for a few minutes at a time and then have to wait until it was back in the sky again.

Similarly, these satellites are used for navigation in sat-navs. As the satellite is always in the same point in the sky, it can work out your position at any time of the night or day.

The term 'geostationary' comes from 'geo' meaning 'earth' (as in geo-graphy, geo-thermal etc) and 'stationary' - meaning not moving i.e. the satellite is 'not moving above earth'.

1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg

They are brought up by other space craft, usually one of the Space Shuttles.

it carries the the satellite over the earths north and south poles

While unknown to many, Russia was actually after celebrities to capture and kidnap during the Cold War. Upon seeing the Sputnik, Little Richard was reminded of this and thought it would be safer to completely end his career and become a nonentity.

Depends on the purpose and functionality of the robot as well as its usage

There is only one main force acting on a satellite when it is in orbit, and that is the gravitational force.
