Artificial Satellites
Artificial Satellites are objects launched from earth to orbit earth or other planets. Satellites are used for communication, remote sensing, weather forecasting, and other purposes. This category is for questions about satellites in general or specific satellites.

Which woman spent a long time in space?
- For the longest single spaceflight by a woman, Sunita Williams holds the record at 195 days.
- Over the span of two spaceflights to the International Space Station, Peggy Whitson spent 376 days, 17 hours and 22 minutes in space
How many satellites does India have in space?
India has launched 56 satellites into space to date. Many of which have since completed their missions and are no longer operational, some have been landed.
In a way.
It's orbit got lower and lower, until it burned up when it started hitting the denser layers of Earth's atmosphere.
Why are satellites important to Earth?
Perhaps one of the most important and controversial uses of satellites today is that of monitoring the Earth's environment. Many satellites study features on the ground, the behavior of the oceans, or the characteristics of the atmosphere. Satellites that observe the Earth to collect scientific data are usually referred to as "Earth observation satellites." Sometimes the interpretation of their data has been controversial because the interpretation is difficult and people have used the data to call for substantial changes in human behavior.
Sputnik was the world's first artificial satellite launched by the Soviet Union in 1957. Its successful launch marked the beginning of the space age and triggered the space race between the Soviet Union and the United States. Sputnik orbited the Earth for three months before burning up upon reentry.
What was the name of the first satellite launched into space?
The first satellite launched into space by Russia was Sputnik. This monumental event took place on October 4, 1957. The timing was 'tweaked' to mark the 40th anniversary of the Russian Revolution of 1917.
Describe three uses of satellites and space stations?
- Communication: Satellites are used for global communication by enabling services such as phone calls, internet connectivity, and broadcasting. They help transmit signals across vast distances efficiently.
- Earth observation: Satellites are used to monitor and track various Earth-related phenomena such as weather patterns, natural disasters, environmental changes, and urban development.
- Scientific research: Space stations serve as platforms for conducting experiments in microgravity environments to study topics like biology, physics, and materials science. They also support astronomical observations and serve as testbeds for future space exploration technologies.
What was the first artificial satellite?
The first artificial satellite to achieve Earth orbit successfully was Sputnik-1.
It was launched by the USSR on October 4, 1957. It spent about 3 months in orbit and was followed by many other unmanned satellites. The first satellite to carry a human was Vostok, in which Yuri Gagarin orbited the Earth in 1961.
The first artificial satellite was Sputnik I, launched by the Soviet Union on the 4th of October 1957
What year was the first satellite launched into space?
Sputnik I was launched by the USSR on October 4, 1957.
What are the differences between natural and man-made structures?
Natural structures are formed by themselves whereas man made structures are built to look like something ...
Who was the first person to launch a satellite to Pluto?
The first person to launch a satellite to Pluto was Bob Riley.
How was sputnik connected to the cold war?
Sputnik was connected to the Cold War as a test of technological prowess between the United States and the Soviet Union to show who could be the first to create a man made satellite orbit the Earth.
When did the satellite come out?
Despite the claims of the radio starting at 1988, Satellite radio started at 1987, with the United States Army fiddling around with the radio.
What star does the earth revolve around?
The Earth and other solar planets revolve around the Sun (Latin sol ). The Sun is a class G2V main-sequence hydrogen-fusing star (its white color appearing yellow due to atmospheric scattering). It is about 1.4 million km (870,000 miles) in diameter, and thought to be about 4.6 billion years old.
The orbit of Sputnik I (first artificial satellite) was highly elliptical, ranging from 223 to 939 kilometres (133 to 533 miles) above the Earth. It orbited for almost exactly 3 months, completing 1440 orbits before burning up on reentry on January 4, 1958.
What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
What was the satellite that was launched by americans in the Cold War?
Explorer I (the first US satellite to orbit the Earth) was launched on January 31, 1958, and discovered the radiation belts known as the Van Allen Belt. Additional satellites were launched to study the radiation. Unfortunately Explorer 2 (March 5, 1958) failed to reach orbit. Explorer 3, also known as Gamma 1, was successfuly orbited on March 26, 1958, becoming the second US satellite in space.
What planet was sputnik 1 supposed to land?
No one.
It was launched into low-Earth orbit and stayed there until it fell back in the atmosphere and burned up.
C What can satellite images tell us about the weather?
Satellites above the atmosphere can get a clear, big picture of Earth's cloud formations. By analysing these cloud patterns, meteorologists can forecast how these clouds will change and move, and predict the weather, be it rain or shine, for many areas. For example, hurricanes can be easily spotted from satellites but not easily spotted from ground due to its size, and thus satellites come in very helpful. Also, infra-red satellite forecasting can also determine the temperatures in different areas on Earth's surface, which aids meteorologists in finding out cloud heights, cloud types, water cycles and sea surface termperatures (an important factor in the formation of hurricanes).
What are the uses of a space probe?
Probes are used to get samples and to also see what there is on other planets
How big is the crashing satellite?
Relax, it already crashed somewhere in the Pacific.
It was roughly the size of a US schoolbus (35 ft long).
