Artificial Satellites

"Sputnik" is a Russian word meaning "satellite" or "companion." It was the name given to the world's first artificial satellite that was launched by the Soviet Union in 1957. The name was chosen to symbolize the satellite as a companion exploring outer space.

The launch of Sputnik marked the beginning of the space age and the opening of the space race between the United States and the Soviet Union. It led to increased investment in science education and research, as well as the establishment of NASA in the United States.

The British Royal Navy launched HMS Dreadnought in 1906. It was considered a revolutionary battleship because it had an "all-big-gun" design, with a uniform main battery of large-caliber guns. This design set a new standard for battleships around the world.

No, Sputnik was not a shuttle. Sputnik was the world's first artificial satellite, launched by the Soviet Union in 1957. A shuttle typically refers to a spacecraft like the Space Shuttle used by NASA for manned spaceflight missions.

Earth has one natural satellite (the moon). There are also several stray rocks in odd orbits but none of these is considered significant or long-term.

The United States Space Surveillance Network is tracking more than 8000 man-made objects in orbit that are 10 cm in diameter or larger. About 560 of these are artificial satellites (i.e. constructed objects intentionally placed in orbit to perform some function), the rest are debris being tracked to prevent its reentry being mistaken for an incoming missile.

The first US communications satellite to amplify radio and TV signals was called Echo 1. It was launched on August 12, 1960, and was a passive communications satellite that reflected signals rather than amplifying them.

The first man-made object to successfully be placed in Earth orbit was dubbed "Sputnik".

It was launched from the Baikonur Cosmodrome in Kazakhstan ... part of the USSR at

Sputnik 2 completed one orbit on its mission on November 3, 1957. It carried the dog Laika, the first living being to orbit the Earth.

It showed that orbiting the Earth was feasible, a vital step towards escaping Earth's gravity. (I've assumed that you mean a man-made satellite, rather than our Moon, which is also a satellite of the Earth.)

The US responded to the USSR's launch of Sputnik in 1957 by ramping up its own space program, leading to the establishment of NASA. This event also spurred increased investment in science and technology education in the US, as well as the development of the National Defense Education Act to advance math and science education.

I guess you are doing Module P5 research study, I have also been struggling on this one and can't find anything to do with it. It is so annoying and we only got 2 lessons to finish writing up so now i am doing it in my lunchtimes the best i have found is located here; http://www.stmary.ws/physics/97/JROTH.HTM

The satellite transponder typically works in either the C-band (4-8GHz) or the Ku-band (12-18GHz) and these are for the downlink (from the satellite to the earth station).

The cost of launching a satellite can vary widely depending on various factors such as the size of the satellite, its weight, the orbit it needs to be placed in, and the launch provider chosen. On average, the cost of launching a small satellite can be around $10-30 million, while larger satellites can cost hundreds of millions of dollars.

The successful launch of Soviet satellites created panic across the US because it demonstrated that the Soviet Union had the capability to send nuclear weapons to the US. This heightened concerns about the US being vulnerable to attack and falling behind in the space race.

Satellites typically orbit in low Earth orbit (LEO) at altitudes ranging from 160 to 2,000 kilometers, in medium Earth orbit (MEO) around 10,000 kilometers, or in geostationary orbit (GEO) at around 35,786 kilometers above Earth's equator. The altitude depends on the purpose and function of the satellite.

The first Indian satellite was named Aryabhata, launched on April 19, 1975. It was named after the ancient Indian mathematician and astronomer.

Examples of navigation satellites include the Global Positioning System (GPS) operated by the United States, GLONASS operated by Russia, Galileo operated by the European Union, and BeiDou operated by China. These satellite constellations provide accurate positioning, navigation, and timing services worldwide.

Titan, Saturn's largest moon, has a diameter of about 5,151 kilometers (3,200 miles), making it the second-largest moon in the solar system.

There 3,000 satellites in space...I think...

The maximum number of channels supported by a single satellite can vary depending on the satellite's design and bandwidth capacity. However, modern communication satellites can typically support hundreds to thousands of channels simultaneously.

To escape Earth's orbit, an object must reach a distance known as the Hill sphere, which is around 1.5 million kilometers from Earth. Beyond this point, the gravitational influence of the Earth is weakened by the influence of the Sun.
