Artificial Satellites

The launch of Sputnik 1 by the Soviet Union in 1957 had a profound impact on America. It led to increased focus on science education and research, the establishment of NASA, and the development of the space race between the US and the USSR. It also triggered the creation of programs like the National Defense Education Act to advance science and technology education in the United States.

Sputnik 2 orbited the Earth for about 162 days before re-entering the atmosphere and burning up on April 14, 1958.

The big grass on an orbiting satellite would be called a park in space!

Satellites send images and data back to Earth using radio waves. The satellite collects the information with its sensors and cameras, processes it, and then transmits it to ground stations on Earth. The ground stations receive the data and images, often through large antennas that are pointed at the satellite as it passes overhead.

I don't know that it failed, but Explorer I was launched in 1958.

A satellite needs to be high above the Earth in order to achieve a stable orbit where it can continuously circle the planet without being pulled down by gravity. Being at a higher altitude allows the satellite to have a wider field of view, better communication coverage, and longer orbital duration.

One idea for building a satellite shield in space is to deploy a network of small satellites equipped with lasers that can deflect or destroy incoming debris. Another concept involves deploying a large net or a cloud of small robotic satellites to capture and remove space debris. These methods aim to reduce the risk of collisions with active satellites and spacecraft in orbit.

Russia has a history of focusing on space exploration, dating back to the Soviet era. The country continues to prioritize its space program for national security, scientific research, and commercial purposes. Having a large number of satellites allows Russia to maintain a strong presence in space, support its military capabilities, and contribute to international cooperation in space exploration.

The idea of building Sputnik, the first artificial Earth satellite, came from Sergei Korolev and his team at the Soviet space program. They were inspired by the concept of exploring space and demonstrating Soviet technological capabilities during the Cold War. The successful launch of Sputnik in 1957 marked a significant milestone in space exploration.

Sputnik 1 was the first artificial satellite launched into space by the Soviet Union in 1957. It marked the beginning of the space age and the space race between the US and the Soviet Union during the Cold War.

A satellite is considered to be in geostationary orbit when it stays in a fixed position above a specific point on Earth's surface. It orbits at the same rate as the Earth's rotation, which allows it to remain stationary relative to the ground below. Geostationary satellites are commonly used for communication and weather monitoring purposes.

Yes, the original Sputnik satellite, launched by the Soviet Union in 1957, re-entered Earth's atmosphere and burned up in 1958. However, there have been multiple other satellites named Sputnik launched since then.

Pinta satellite legions are a classification of cells found in the outer layer of the bone marrow, known as the endosteal niche, that have a specific role in regulating hematopoiesis (the formation of blood cells). They play a crucial role in maintaining the balance between proliferation and differentiation of blood stem cells.

If a satellite slows down, it will start to move closer to Earth as gravity becomes more dominant. This can lead to its orbit decaying and potentially reentering the Earth's atmosphere. Additionally, a slowdown could affect the satellite's ability to maintain its position for communication or observation purposes.

Very few satellites are ever recovered. If a satellite is no longer doing its job,

for whatever reason, and it can still be controlled from the ground, then it's

orbit will be intentionally changed to one that skims the atmosphere. After

that, it doesn't take long before the satellite completely "falls" out of orbit,

and burns up in the atmosphere.

If a satellite no longer responds to remote command and control, then there's

nothing that can be done with it except to track it. It has graduated into the

category of "Space Junk", and it'll continue to go where the laws of Physics

take it. The only remaining task of any interest is to know where it is at all

times, so that future space missions can avoid it.

RISAT-2 was launched by ISRO to provide all-weather surveillance using synthetic aperture radar (SAR) imaging for strategic and defense purposes. It helps in monitoring agriculture, forestry, soil moisture, and disaster management as well.

The Soviet Union was the first country to launch Intercontinental Ballistic Missiles (ICBMs). The R-7 Semyorka, also known as the R-7 ICBM, was the first ICBM and was developed by the Soviet Union in the late 1950s.

The height of a geostationary satellite from the surface is approximately 35,786 kilometers (22,236 miles).

Aryabhata, India's first satellite, was launched by the Soviet Union (now Russia) on April 19, 1975.

Yes, artificial satellites can provide evidence that the Earth is a sphere. Satellites orbiting the Earth take images showing its curved surface, and measurements of the Earth's shape can be made based on satellite data. Additionally, the way satellites maintain their orbits around the Earth is consistent with the Earth's spherical shape.

The Zeppelin airship, named "LZ1," was launched in 1900 in Germany by Count Ferdinand von Zeppelin. It was the first successful airship and paved the way for future advancements in air transportation.

There is different types of artificial satellites, each for different uses. For example :

Weather satellites help meteorologists predict the weather or see what's happening at the moment. Typical weather satellites include the TIROS, COSMOS and GOES satellites. The satellites generally contain cameras that can return photos of Earth's weather, either from fixed geostationary positions or from polar orbits.

Communications satellites allow telephone and data conversations to be relayed through the satellite. Typical communications satellitesinclude Telstar and Intelsat. The most important feature of a communications satellite is the transponder - a radio thatreceives a conversation at one frequency and then amplifies it and retransmits it back to Earth on anotherfrequency. A satellite normally contains hundreds or thousands of transponders. Communications satellites are usually geosynchronous. Broadcast satellites broadcast television signals from one point to another.

• Scientific satellites perform a variety ofscientific missions. The Hubble Space Telescope is themost famous scientific satellite, but there are many others looking at everything from sun spots to gammarays. ( See the article of the telescopes)

-> Hiten scientific satellite

• Navigational satellites help ships and planes navigate. The most famous are the GPS NAVSTAR satellites, r escue satellites respond to radio distress signals.

-> NAVSTAR satellite

• Earth observation satellites observe the planet for changes in everything from temperature toforestation to ice-sheet coverage.

-> ENVISAT

• Military satellites are up there, but much of the actual application information remains secret. Intelligence-gathering possibilities using high-tech electronic and sophisticated photographic-equipment reconnaissance are endless. Applications may include relaying encrypted communication, nuclear monitoring, observing enemy movements, early warning of missile launches, eavesdropping on terrestrial radio links, radar imaging, photography (using what are essentially large telescopes (see the article on the telescopes ) that take pictures of militarily interesting areas)

Gemini missions were launched from the United States in the 1960s as a part of the American space program.

The first satellite, Sputnik 1, was launched into space by the Soviet Union on October 4, 1957. This event marked the beginning of the Space Age and the start of the space race between the US and the Soviet Union.

The Bismarck battleship was launched on February 14, 1939 in Hamburg, Germany.
