Artificial Satellites

The launch of Sputnik 1 on October 4, 1957, was a Soviet Union achievement led by Chief Designer Sergei Korolev and his team at the OKB-1 design bureau. The satellite was launched using a R-7 Semyorka rocket, designed by Chief Engineer Mikhail Yangel.

A satellite in a geostationary orbit stays fixed over one location on Earth, making it ideal for continuous communication and relay procedures between ground stations. This eliminates the need for tracking and pointing mechanisms, ensuring a stable connection for extended periods. Additionally, the high altitude of geostationary orbit allows for wide coverage, enabling communication over a large area.

The first artificial satellite released was Sputnik 1, launched by the Soviet Union on October 4, 1957. It marked the beginning of the space age and the start of human-made objects orbiting the Earth.

I think Chinese was the first to build a rocket it consists of an arrow with tube filled with gun powder it was about 600 A.D.

The Muslim Arabs developed the rocket with the same shape we know these days it was about 1100 A.D They used rockets in their wars but it were not accurate.

I saw some old paintings showing two soldiers launching rocket and some people watching them the picture was belong to the Usmanian era so it may be in 1600 A.D

The centripetal force due to gravity decreases as the satellite moves farther from Earth because the force of gravity weakens with distance. This is in accordance with the inverse square law, which states that the force of gravity decreases with the square of the distance between two objects.

If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.

A polar satellite is a type of satellite that orbits the Earth in a north-south direction, passing over both poles. Two uses of polar satellites are weather forecasting, as they can provide global coverage of weather patterns, and environmental monitoring, such as tracking changes in ice caps and studying climate change.

A rocket takes off from Earth by igniting its engines to produce thrust, which propels it upwards against the force of gravity. The thrust generated must be greater than the force of gravity in order for the rocket to overcome Earth's gravitational pull and lift off into space. Once the rocket reaches a certain speed and altitude, it can transition to its intended trajectory.

A satellite Video PID (VPID) is a unique identifier that is used to assign a specific video stream within a satellite transmission. It helps receivers to identify and decode the video data accurately from the satellite signal.

The first five year plan in India was launched in the year 1951. It focused on agriculture, irrigation, and power generation to promote economic development in the country.

Sputnik was 23 inches in diameter and was about the size of a basketball.

No.

Sputnik 1 burned up on 4 January 1958, as its decaying orbit brought into into Earth's atmosphere.

The first satellite was launched more than 50 years ago. It was Sputnik in 1957.

As of 2021, NASA has several operational satellites in space, including those dedicated to Earth observation, communications, and space exploration. The exact number can vary as some satellites are retired or decommissioned.

Navigation satellites move around Earth at an altitude of about 1,243 miles to 22, 223 miles and at about the same speed of rotation. These satellites are in what is called Medium-Earth orbits (MEO).

A satellite in a geostationary orbit goes around the earth at the same angular speed that the earth spins on its axis. So to someone on the earth the satellite looks like its not moving because its always at the same location above the earth. These satellites are used for communication purposes. For example, TV stations can reflect their signal off of such a satellite by aiming their transmitter at it. They don't have to change their aim because the satellite is always there. Satellite dish receivers can easily pick up the reflected signal just by aiming the dish antenna at the satellite and again you don't have to change this aim because the satellite is always there. The satellites have to be in a circular orbit above the equator in order for it to be put in a geostationary orbit.

A Geostationary orbit - it means that the satellite will always stay above the same point on Earth.

Hope that helps

Space satellites rely on solar energy for power. Solar panels on the satellite convert sunlight into electricity to power the various systems onboard. The use of solar energy allows satellites to operate efficiently in space where other energy sources may not be available.

The first satellite of the Philippines is named Diwata-1. It was launched into space in 2016 as part of the joint development program between the University of the Philippines and the Department of Science and Technology.

As of 2021, there are around 80 countries with active satellites in orbit around Earth. These satellites serve various purposes including communication, weather monitoring, Earth observation, and scientific research.

Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.

the name of the satellite was called Explorer

Satellites are used for various purposes such as communication, weather forecasting, navigation, Earth observation, scientific research, and national security. They enable global connectivity, support disaster relief efforts, monitor climate change, facilitate precision agriculture, and assist in understanding the universe beyond Earth.

Yes, the original Sputnik satellite launched by the Soviet Union in 1957 is no longer in space. It re-entered the Earth's atmosphere and burned up many years ago.

Voyager 2 is currently in interstellar space, having crossed the boundary of our solar system in 2018. It continues to transmit valuable data back to Earth, contributing to our understanding of the outer regions of our galaxy.
