These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth and learn more about the world in which we live.
How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed toward the earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3) ________ toward the earth while still hovering over its surface.
A satellite is said to be in geo-stationary orbit when it completes one revolution around the earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth.

Each planet in the solar system has unique characteristics and features. 3._____________ planets, such as Mercury and Venus, are small and rocky, while others, like Jupiter and Saturn, are much larger and made up mostly of gas. The outer planets, Uranus and Neptune, are 4._________ as ‘ice giants’ because they contain more water, ammonia, and methane than the gas giants. In addition to the planets, the solar system also has numerous moons, asteroids, and comets. These objects provide important 5._______ about the formation and evolution of the solar system.

The Sun is the star at the center of (1) __________ Solar System. It is a nearly perfect ball of hot plasma. The Sun has inspired us since ancient times. It’s central to mythology and religion in (2) ____________ around the world. It keeps our planet warm enough for living things to grow. It gives us light so we can see. It is by far the most important (3) _________of energy for life on Earth. It is about a hundred times as wide (4)________ the Earth. If there were no sun, many things wouldn’t occur like photosynthesis or the presence of oxygen, which would have caused no (5) __________ of life.

Any (1) ________that revolves around a planet is a satellite. Mother Earth has a natural satellite in the moon. The earth is circled by a lot of man-made or artificial satellites. In 1957, the Soviet Sputnik was the first to be (2) ________into space. There are currently a number of artificial satellites launched into space by various nations.
These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth and learn more about the world in which we live.
How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed toward the earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3) ________ toward the earth while still hovering over its surface.
A satellite is said to be in geo-stationary orbit when it completes one revolution around the earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth. These orbits are typically used by satellites for communication and weather. The camera on the weather satellites takes pictures and sends them back to Earth. These are helping aid in weather forecasting. Radio receivers and amplifiers on communication satellites can (4) ________ waves back at a frequency that is different from the one the satellite received. The beaming frequencies of satellites that are ‘parked’ too close to one another must not interfere with one another. Television signals can be transmitted from one location to other using broadcast satellites, and scientists can (5)________ scientific data from numerous satellites.
