Artificial Satellites

In 1957, the major event was the launch of the Soviet satellite Sputnik, which became the first artificial Earth satellite. This event marked the beginning of the space age and the space race between the US and the Soviet Union. It also led to the establishment of NASA in the United States in response to the perceived technological and military threat posed by Sputnik.

Without satellites, our global communication, navigation, and weather forecasting systems would be severely disrupted. This would impact activities such as international travel, disaster response, and financial transactions. Additionally, scientific research, environmental monitoring, and military operations that rely on satellite data would be significantly hindered.

North Korea launched its first satellite into space in 2009.

Satellites send information. They can also take pictures of different items. Also, Satellites can help stranded boaters as well. They can also relay signals, which is what makes satellite T.V. possible.

Yes, the gravitational field can affect the frequency of a satellite. In stronger gravitational fields, such as near massive celestial bodies, the satellite's orbit may experience time dilation effect due to general relativity, causing a shift in the frequency of signals transmitted between the satellite and ground stations.

There are several types of artificial satellites, including communication satellites for transmitting signals between locations, weather satellites for monitoring and predicting weather patterns, navigation satellites for providing accurate positioning information, and observation satellites for taking images of Earth's surface for various purposes. Additionally, there are also scientific research satellites for conducting experiments and gathering data in outer space.

The first Indian communication satellite was named "Rohini" and it was launched on April 19, 1980. It was part of the INSAT series of satellites and played a key role in revolutionizing communication and broadcasting services in India.

Air currents are caused by the sun's uneven heating of the earth, Water Currents (mostly known as Ocean Currents) are generated by wind, density differs in water masses causes by temperature and salinity variations,gravity, and also events such as earthquakes

The first people to use artificial dyes were the ancient Egyptians, who used natural resources to create colored pigments for paintings and textiles. The synthetic dyes industry began to develop in the mid-19th century with the discovery of synthetic dyes like mauveine by Sir William Henry Perkin.

The cost of building Sputnik 2, the second spacecraft launched into Earth's orbit by the Soviet Union in 1957, was estimated to be around 7.5 million rubles at that time. Adjusted for inflation, this would be approximately $6.5 million USD in today's currency. The spacecraft was significantly more complex and expensive than its predecessor, Sputnik 1, due to the addition of a life-support system for the dog Laika, who became the first living being to orbit the Earth.

Satellite information is important because it provides real-time data on weather patterns, natural disasters, climate change, and environmental changes. It is also crucial for communication, navigation, surveillance, and monitoring of infrastructure such as pipelines, agriculture, and transportation systems. Additionally, satellite data helps in conducting scientific research, exploring space, and ensuring national security.

Yes, a satellite in orbit requires fuel to make adjustments to its trajectory or maintain its position. However, satellites in geostationary orbit can maintain their position without fuel because they orbit above the same location on Earth.

Sputnik 1 was in orbit for about three months, from October 4, 1957, to January 4, 1958.

Satellite images provide visual representations of Earth's surface, showing features like land use, weather patterns, and natural disasters. This information is important for various reasons such as monitoring environmental changes, urban planning, disaster response, agriculture management, and scientific research.

Geostationary refers to an object, such as a satellite, that orbits the Earth at the same speed and direction as the Earth's rotation, resulting in it appearing stationary from a fixed point on the Earth. This orbit is typically located at an altitude of about 35,786 kilometers above the equator.

A satellite in a geostationary orbit orbits the Earth at around 22,300 miles above the equator. Geostationary satellites appear to be stationary in the sky relative to a fixed point on the Earth's surface, making them ideal for communication and weather monitoring.

The first artificial satellite, Sputnik 1, was created by the Soviet Union. It was launched into orbit on October 4, 1957.

The Sputnik 2 mission was controversial because it carried the first living creature into space, a dog named Laika, who unfortunately died during the mission. This raised ethical concerns about the use of animals in space exploration and sparked public outcry over animal welfare. Additionally, the rushed nature of the mission highlighted the competition between the United States and the Soviet Union in the space race.

72 + 35 (foreign) satellites were put into orbit so far (till November 2013).

Yes, a pendulum can vibrate in an artificial satellite since motion in a satellite is relative and independent of gravity. However, because artificial satellites are typically in a state of free fall or orbit around a celestial body, the motion of a pendulum may appear more complex due to the satellite's acceleration and movement.

There are thousands of satellites currently orbiting the Earth. The exact number can vary, as new satellites are launched and old ones are decommissioned regularly.

Sputnik 2, launched November 3, 1957.

Sputnik 1 was the first man-made Earth satellite, and Sputnik 2 was the second. Sputnik 2 carried a dog, Laika, as the first astronaut. The dog died a few hours after launch.

The USA did not launch its first satellite, Explorer 1, until about 3 months later, on January 31, 1958.

Apart from the United States, other countries with active satellite programs include Russia, China, India, Japan, and various European countries through the European Space Agency. Additionally, countries such as Canada, South Korea, Israel, and Brazil also have their own satellites in space.

Uranus has 27 known artificial satellites as of now. These satellites are typically referred to by numbers rather than names.
