The first weather satellites allowed meteorologists and forecasters to see Earth from space and get a larger picture of cloud formations from above. The program was called TIROS and there were 10 satellites in the series. (A good link is provided below) Prior to TIROS, there were few options available to help meteorologists to predict the weather.

The force of gravity is responsible for continuously changing the what of a satellite?
The force of gravity is responsible for continuously changing the velocity or speed of a satellite as it orbits around a larger body, such as a planet or a star. This change in velocity helps to maintain the satellite's orbit and keep it in motion around the larger body.
Why at height the artificial sateillte not pulled toward the earth?
The satellite is being pulled by the earths gravity all of the time, but the satellite also has an orbital velocity, meaning that is is travelling at high speed. These two opposing forces balance out, the 'sideways' speed of the satellite wants to take it away into space, but the gravity of the earth is always pulling it in. The satellite maintains its speed as there there are no frictional forces to slow it down in space, so it maintains an orbit.
Is it possible to place a satellite in geosynchronous orbit at a much lower altitude?
No. To remain in orbit it needs to have a certain speed, and that speed will only match the surface speed of the earth on a certain height. To go lower it'd have to go slower, and then it'd fall.
What does the work-energy theorem say about the speed of a satellite in circular orbit?
Not very much, I would say. There is no work being done in this situation so there's no change in kinetic energy. So the satellite's speed remains constant. But we already knew the speed was constant. Perhaps I'm missing something.
Why do satellites need to reach a specific speed to escape earths surface?
Satellites need to reach a specific speed, known as escape velocity, to overcome Earth's gravitational pull and enter orbit or travel into space. This speed, approximately 11.2 kilometers per second (about 25,000 miles per hour), allows them to break free from the gravitational attraction without falling back to Earth. Achieving this speed ensures that the satellite can maintain a stable trajectory and avoid being pulled back by gravity. If a satellite doesn't reach this speed, it will not be able to escape Earth's atmosphere and will eventually descend back to the surface.
If the mass of a statellite is doubled while the radius of its orbit remains constant then the speed of the satellite is increased by how much?
The speed of the satellite will remain the same regardless of doubling the mass, as long as the radius of its orbit remains constant. The speed of the satellite in orbit is determined by the gravitational force between the satellite and the celestial body it is orbiting, not the mass of the satellite itself.
As a satellite spirals inward, does it speed up, slow down, or maintain the same speed during its journey?
As a satellite spirals inward, it speeds up due to the gravitational pull increasing as it gets closer to the center of the object it is orbiting.
What is the speed of satellite?
A satellite has to maintain 1800miles/hr. around the Earth. If its speed were to speed up the satellite would fly off in to space. If the satellites speed were to slow down it would come crashing into Earth.
What does speed affect orbiting altitude?
Speed affects orbiting altitude because the balance between gravitational pull and the orbital velocity determines a satellite's position in orbit. A higher speed allows a satellite to maintain a stable orbit at a lower altitude, as the increased centrifugal force counteracts gravity more effectively. Conversely, if the speed decreases, the satellite must move to a higher altitude to maintain a stable orbit, as the reduced centrifugal force would cause it to fall back toward the Earth. Thus, the orbital speed and altitude are intrinsically linked through gravitational dynamics.
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
What is the Only the mass of the planet and radius of the orbit are needed to calculate the orbital speed of a satellite.?
The orbital speed of a satellite can be calculated using the formula ( v = \sqrt{\frac{GM}{r}} ), where ( v ) is the orbital speed, ( G ) is the gravitational constant, ( M ) is the mass of the planet, and ( r ) is the radius of the orbit. The mass of the planet determines the gravitational pull on the satellite, while the radius of the orbit affects the distance from the center of the planet. Together, these two factors allow us to determine the speed needed for the satellite to maintain a stable orbit.
What best describes the impact of satellite technology?

What communicates with a satellite dish to provide high-speed internet connections via satellite?

What is the orbital speed of low orbit satellite?
The orbital speed of a low Earth orbit (LEO) satellite, typically at altitudes around 200 to 2,000 kilometers, is approximately 7.8 kilometers per second (about 28,000 kilometers per hour or 17,500 miles per hour). This speed allows the satellite to balance gravitational forces and maintain a stable orbit around the Earth. Variations in altitude can slightly affect this speed, but it generally remains within this range for LEO satellites.
If the speed of an orbiting satellite decreases how might you expect it and otbit to change?
If the speed of an orbiting satellite decreases, it will begin to lose altitude and spiral closer to the Earth due to the reduced centripetal force needed to maintain its orbit. As it descends, the gravitational pull becomes stronger, further accelerating its descent. Eventually, if the speed continues to decrease, the satellite may re-enter the atmosphere and burn up or crash. The orbit will become more elliptical and unstable as the speed decreases.
The force of gravity is responsible for continuously changing the what of a satellite?
The force of gravity is responsible for continuously changing the velocity or speed of a satellite as it orbits around a larger body, such as a planet or a star. This change in velocity helps to maintain the satellite's orbit and keep it in motion around the larger body.
A satellite in an elliptical orbit loses speed when it?
A satellite in a closed orbit has the greatest speed when it's closest to the planet, and the lowest speed when it's farthest from the planet.
