Artificial Satellites

Satellites are unmanned spacecraft, and the term unmanned space vehicle could also apply. A spacecraft is a vehicle or machine that is used in space, and there are many different kinds with a variety of missions. Satellites are used for communications, navigation, and planetary observation (including exporation, meteorology and intelligence gathering) to name a few of their applications. Use the link below to learn more about spacecraft.

Satellites improve communication by enabling instant global connectivity, facilitate navigation with GPS systems, monitor weather patterns for better predictions, support disaster response efforts by providing real-time mapping and imagery, and assist in agriculture, forestry, and urban planning by supplying data from space.

For a satellite to stay in one place over the earth, the satellite must be going in orbit in the same direction that the earth spins. The satellite must also travel at the same pace/speed as the earth spins to give us the 24-hour day that we as people witness.

To apparently stay in one place it must be in a synchronous orbit. For the earth this is about 24,000 miles altitude. It must also be an equatorial satellite.

Variable inlet guide vanes (VIGV) are typically used in satellite compressors to allow for capacity variation. These vanes can control the airflow entering the compressor, thus adjusting the compressor's capacity.

Without satellites, communication, navigation, weather forecasting, and remote sensing would be severely impacted. It would be more challenging to monitor natural disasters, track climate change, and conduct scientific research that relies on satellite data. Additionally, industries such as transportation, agriculture, and disaster response would face significant disruptions.

I'm unable to provide a comprehensive list of all artificial satellites launched in the past five years, as there have been hundreds of satellite launches during that period. You can find information on recent satellite launches by checking websites like the European Space Agency, NASA, SpaceX, and other organizations involved in satellite launches.

(The Russians called it "Sputnik" at the time.)

Yes, Woomera in Australia was used as a launch site for satellites in the past. The WRESAT satellite, launched in 1967, was Australia's first satellite and was launched from Woomera. Additionally, a number of other satellites were also launched from Woomera in the following years.

Some artificial satellites launched before Cartosat-2A include Sputnik 1 (1957), Explorer 1 (1958), Telstar 1 (1962), and Landsat 1 (1972).

China launched its first artificial satellite on October 24, 1970. The satellite was named Dong Fang Hong 1 (DFH-1).

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

the time ... on October 4, 1957.

Satellites typically use liquid rocket fuels such as liquid hydrogen or a combination of liquid hydrogen and liquid oxygen for propulsion. These fuels are chosen for their high energy content and efficiency in the vacuum of space. Solid rocket fuels can also be used in some satellite systems for specific purposes.

There have been several Sputnik satellites launched since the first one in 1957, including Sputnik 1, 2, 3, and so on. The exact number of Sputnik satellites launched is not readily available due to variations in naming conventions and differences in satellite designations over time.

The team that invented Sputnik 1, the world's first artificial satellite, was led by Sergei Korolev, a chief designer at the Soviet Union's R-7 rocket program. The team included many engineers, scientists, and technicians who worked together to successfully launch Sputnik 1 into orbit on October 4, 1957.

A negative impact on a satellite could be damage caused by space debris colliding with the satellite, which can result in malfunctions or complete loss of the satellite. Additionally, exposure to high levels of radiation in space can degrade the satellite's components over time, affecting its performance.

None.

It was launched into low-Earth orbit and stayed there until it fell back in the atmosphere and burned up.

As of 2021, there are over 3,000 artificial satellites orbiting the Earth. Some well-known satellites include the International Space Station (ISS), Hubble Space Telescope, and Global Positioning System (GPS) satellites.

The first manmade satellite, Sputnik 1, was launched into orbit by the Soviet Union on October 4, 1957. This event marked the beginning of the space age and the era of artificial satellites.

A Satellite movement behaves in two ways. Its orbit may be defined either as "geosynchronous" or "geostationary". Geosynchronous satellites move together with the Earth's own orbit, so it revolves in the same way as the earth is. Geostationary satellites remain statically in place for a certain coordinate...

The geostationary satellites of India are INSAT (Indian National Satellite System) series. This series includes satellites like INSAT-3A, INSAT-3C, INSAT-4A, INSAT-4B, and GSAT- series satellites. These satellites provide communication, broadcasting, meteorological, and search and rescue services across India.

Satellites themselves are not dangerous. They are placed in orbit around Earth to provide various services like communication, weather monitoring, and navigation. However, if a satellite were to malfunction or collide with another object in space, it could potentially create debris that poses a hazard to other satellites and spacecraft.

The information from radar and satellites is obtained remotely from above the Earth's surface, providing a broader perspective of the area being observed. This data is collected through sensors and instruments on satellites or radar systems, allowing for continuous monitoring over large areas. On the other hand, information from ground stations is collected locally from specific points on the ground, offering more detailed and precise data but limited to a smaller area of coverage.

the force of gravity on the moon is much weaker than that of earth. that means that you are getting pulled down more on earth than you are on the moon resulting in a lighter weight.

About 1/6 of your weight on earth. See many related answers, all of which say the same, but with various extra information.

In addition , the public feared that the Soviets' ability to launch satellites also translated into the capability to launch ballistic missiles that could carry nuclear weapons from Europe to the US.

The force of gravity is responsible for changing the velocity of a satellite, thus affecting its path or trajectory in space. This force influences the satellite's speed and direction, causing it to move in an elliptical orbit around a larger body such as a planet or a star.
