Artificial Satellites

The first artificial satellite in space was called the Sputnik. The Sputnik satellite was launched on the 4th of October, 1957. It belonged to the Soviet Union.

The United States has launched the most number of satellites into space.

Sputnik 1 was invented by the Soviet Union and was launch on October 4, 1957. It was the first artificial satellite successfully launched.

A space satellite is a man-made object launched into space to perform various functions, such as communication, remote sensing, weather monitoring, navigation, and scientific research. Satellites orbit the Earth and can be stationary or move in specific paths depending on their purpose.

Natural satellites are celestial bodies that orbit larger objects in space, such as planets, while artificial satellites are man-made objects launched into orbit around Earth for various purposes like communication, weather monitoring, and scientific research. Natural satellites, like the Moon, are formed naturally through gravitational forces, while artificial satellites are specifically designed and created by humans.

Old satellites either remain in orbit as space debris, eventually falling back to Earth and burning up in the atmosphere, or are intentionally deorbited and moved to a "graveyard" orbit to reduce the risk of collision with operational satellites. Some may also be repositioned for alternative uses or repurposed for different missions.

it eaither becomes space junk or dosent work anymore

Several years ago many just became dead objects orbiting, and often termed space junk now. Now decommissioned satellites are brought back in on a controlled re-entry to burn up in the atmosphere. Some are repaired like the Hubble, while some catastrophic failures having no operational control left of the satellite get shot down, like in Feb, 2008 because of its hydrazine fuel aboard.

Occasionally you hear in the news of a satellite crashing back to earth from being dead years ago like a recent one that crashed in Australia.

Skylab was left abandoned to burn up in the atmosphere. It is a good point to note that all objects orbiting in space still experience the forces of drag friction and gravity. Modern satellites are continuously readjusted buy on board engines, usually of a chemical nature. Surprisingly most simply will not last beyond 20 years. It is a very harsh environment to design for.

Thankfully we take a no fail mission safe approach to space vehicles. From Venera, to Viking's, Voyager's, Mars lander's, Gallileo, on and on, are all nuclear powered.

I thing 2700 satellites are in Space right now I am Javed Alam Saifi S/O Mr.Irshad Alam Saifi I lived In Jasola Old village (New Delhi) now Before time I lived in Mukarpur Satti (UP). Thanking For It Seen. By :- J.A.S

A satellite takes a picture by capturing light reflecting off Earth's surface with its onboard camera(s). The satellite's imaging system converts the light into digital data that is transmitted back to Earth for processing and analysis.

Because of the large distance between satellites, distances from Earth to distant stars and planets can be determined more accurately (greater parallax). Also, on board cameras can better view objects on Earth in 3 dimensions.

Man-made satellites are artificial objects placed into orbit around Earth or other celestial bodies to perform various functions such as communication, weather monitoring, navigation, and scientific research. They are launched into space by rockets and are designed to orbit the Earth at different altitudes depending on their specific purpose.

On January 31, 1961, the United States launched the Mercury-Redstone 2 rocket into space. A chimp named Ham was aboard the space rocket.

It is two times the size of a soccer ball.

Pioneer 5

Actually: it was Vanguard 1 March 17, 1958 The first use of solar power dates back to March 17, 1958 when Vanguard 1 was launched utilizing six solar panels which provided less than one watt of power for over six years with a 10% conversion efficiency.

Satellites help solve communication challenges by enabling global connectivity through services like telecommunication, internet access, and broadcasting. They also assist with weather forecasting, disaster response, environmental monitoring, and navigation.

Yes, in 1962, the U.S. satellite Explorer 6 re-entered Earth's atmosphere and disintegrated upon re-entry. This event marked the first time a satellite's re-entry was observed by people on the ground.

The Soviet Union launched Sputnik 1 into space in 1957, marking the beginning of the space age and the first artificial satellite to orbit Earth.

At the time of the sputnik launch, the human race had never launched anything into orbit before, so it was an interesting scientific and technological question to determine of this could be done. And artificial satellites have indeed proved over the years to have very important uses - communication satellites, global positioning satellites, spy satellites etc.

What happiened was that sputnik1 was launched on October 4.1957.It was launched because it needed to gather information about the enemys but in the first few hours,the satilellte lost memory and couldnt gather more information.

NASA isn't exactly sure. The satellite had failed, so it was difficult to track. But they're sort-of confident that it fell into the north Pacific ocean.

Russia

The Soviet Union invented Sputnik, the first man-made satellite to orbit Earth.

It was made in Russia and it was the first Earth-orbiting artificial satellite. It was launched into an elliptical low earth orbit by the Soviet Union on 4 October 1957, and was the first in a series of satellites known as the Sputnik program. The unanticipated announcement of Sputnik 1's success precipitated the Sputnik crisis in the United States and ignited the Space Race during the Cold War.

You're describing the wavelike line that shows up on the maps at mission control when they
plot the path of the spacecraft that they've just launched.

Try to imagine this:

The satellite is circling the earth at a constant rate ... say one orbit every couple of hours. At the same time,
the earth is rotating under the satellite, one complete spin every 24 hours.

Add these two motions together, and you'll see that a point on the ground ... if it always stays directly UNDER
the satellite ... will trace that 'wave' shape on the ground.
