Artificial Satellites

They are placed on top of a rocket, which accelerates them until they "escape" the atmosphere and enter space. Satellites are spacecraft that orbit the Earth or a planet, while those that travel through space are usually called "space probes."

There was more than one Sputnik. Sputnik was a common name for vehicles in the early Russian / Soviet Space programme, Sputnik 1, Sputnik 2 etc

They were all invented by the Russians AKA Soviet Union.

The team, at least for the first Sputniks, was lead by Sergei Korolev

Space Shuttles have people inside then but Sputnik don't

The two have just about nothing in common....they were both launched by rockets - although very different ones. It would be useful to check out the links to the left to see the huge difference.

Mostly it consisted of engineering data, information on different types of radiation, and biological data from the ill-fated canine pasenger, Laika.

See the Web Link to the left for further information.

During this time there were two world powers: US and USSR, both with a totally different lifestyle (democracy and communism). The space race showed USSR was more advanced then we in the United States. It showed the rest of the world that communism was the way to go, and then the red scare and domino effect started coming around.

The question should probably read "What do waves have to do with satellites". Assuming you're asking about the communication satellites in orbit around the earth, the signals that send the information to the satallites and back to the earth are called radio waves or micro waves. This looks like it will explain the concept. http://www.ieee-virtual-museum.org/exhibit/exhibit.php?taid=&id=159265&lid=1&seq=11&view=

Objects in near Earth orbit experience some drag from the from from the atmosphere. (Mind you, it would take a very sensitive instrument to measure atmospheric pressure at 60 miles up.) The answer to the question is that given enough time, the drag will cause the satellite to lose so much momentum that it will crash into Earth. The most famous example of this was Skylab which was launched into orbit in 1973 and burned up in the atmosphere in 1979.

Sputnik 1 changed mankind because it was the first satellite in the world to ever be launched. It was launched by the Soviet Union. This was the beginning of the people around the world really becoming interested in space and space travel and finding the importance for the funding etc.

The first satellite, Sputnik 1, was invented in the Soviet Union by a team of scientists and engineers led by Sergei Korolev. It was launched on October 4, 1957, marking the beginning of the space age.

The idea of an artificial satellite goes back at least as far as the prototype science fiction story "The Brick Moon".

The idea that actual, real satellites could perform useful work goes back to about 1947, when science fiction author Arthur C. Clarke realized that satellites orbiting the equator at about 22,000 miles out, would appear not to move in the sky. You could aim an antenna at it and leave it. Thus you could make communications satellites that could transmit a signal from anywhere on Earth to anywhere on Earth, just by having 3 satellites spaced around the Earth.

The first actual, real satellite was Sputnik, sent up by the Russians in the late Fifties.

Government space agencies, private aerospace companies, and international organizations can launch satellites into space. These entities have the technology, expertise, and resources needed for satellite launches. Additionally, some universities and research institutions may also have the capability to launch small satellites.

Mimas is a large moon of Saturn. Metis is a moon around Jupiter.

The system of satellites used for determining location on Earth is called the Global Positioning System (GPS). It consists of a network of satellites that orbit the Earth and transmit signals to GPS receivers, allowing them to accurately determine their location, speed, and time anywhere on the planet.

it made it easier to go from one place to another .

Gumboots are typically made from rubber or PVC. These materials make the boots waterproof and durable for various outdoor and wet conditions. Some gumboots may also have a fabric lining for added comfort and warmth.

1. Monitoring changes in land use and land cover over time, such as deforestation or urbanization.
2. Tracking sea surface temperatures and currents to monitor ocean circulation patterns and predict the development of tropical storms.
3. Observing variations in atmospheric composition and concentration of greenhouse gases to study climate change trends.

Artificial satellites provide real-time data on weather patterns and enable meteorologists to track and predict weather conditions accurately. Communication satellites facilitate the transmission of weather data and forecasts to various parts of the world, helping in timely warnings and disaster management. Overall, satellites play a crucial role in enhancing weather forecasting and communication infrastructure globally.

Most satellites orbit Earth in the low Earth orbit (LEO) which is between 160 to 2,000 kilometers (100 to 1,240 miles) above the Earth's surface.

MEO (Medium Earth Orbit), HEO (High Earth Orbit), and GEO (Geostationary Orbit) are all circular orbits. Each of these orbits have specific altitudes and characteristics that make them ideal for different types of satellites and missions.

Skylab orbited the Earth for approximately six years and operated from May 1973 to July 1979. Its orbit decayed over time, leading to an uncontrolled re-entry into the Earth's atmosphere in 1979.

The Global Positioning System (GPS) is a satellite-based system that helps us locate places on Earth with accuracy. It consists of a network of satellites that transmit signals to GPS receivers, allowing users to determine their precise location using trilateration. GPS is widely used for navigation, mapping, and various location-based applications.

There are not. In fact, there are no satellites which remain in either the northern or southern hemispheres. Every satellite spends equal time passing over each of them.

The only minor exception would be communications satellites in equatorial geosynchronous orbits, where the satellite is essentially "parked" over one spot above the equator.

Elmo: See the Discussion Page for my answer. Thanks.

A space satellite is any man-made object that orbits Earth or another celestial body, while an Earth satellite specifically orbits Earth. Additionally, space satellites can include artificial satellites launched into space for various purposes, while Earth satellites can refer to natural objects like the Moon that orbit our planet.

Yes, both natural and artificial satellites typically have elliptical orbits. These orbits are determined by the gravitational pull of the body they are orbiting, with the shape of the ellipse varying depending on the eccentricity of the orbit.
