Sputnik

Sputnik led to the space race and the development of the Apollo program. It proved that humans could successfully launch objects into Earth's orbit, paving the way for space exploration and satellite technology.

The first Russian satellite, Sputnik 1, orbited the Earth on October 4, 1957. It was the world's first artificial satellite to be launched into space.

Sputnik traveled at an average speed of 27,600 kilometers per hour (17,100 miles per hour) in its orbit around Earth. Its orbit took approximately 96.2 minutes to complete one revolution around the planet.

The first telecommunication satellite was called Telstar 1, launched by NASA in 1962. It allowed for live transatlantic television broadcasts and telephone calls.

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.

Sputnik was a satellite, so there were various instruments and technology inside the sphere, including radio transmitters and batteries for power. These components allowed Sputnik to transmit data back to Earth and pave the way for future space exploration.

The total cost of Sputnik 2, including its development, launch, and mission operations, was estimated to be approximately $3.9 million USD. This 1957 mission carried the first living creature, a dog named Laika, into orbit.

Sputnik 1 is named after the Russian word for "satellite" or "companion of the Earth." The word "Sputnik" also means "travelling companion" or "fellow traveler." The name was chosen to reflect the satellite's purpose of being the first artificial Earth satellite to orbit the planet.

Disadvantages of satellites include high costs for manufacturing and launching, vulnerability to space debris and damage from solar radiation, limited lifespan due to fuel constraints, and potential for signal interference.

I shall assume you mean mass. 83.6Kg. or 184.3Lb.

Sputnik 1 was designed by the Russians. The year 1957 saw the beginning of the "Space Age", and the beginning of the "Space Race" between the USA and the USSR. The Soviet Union became the first to launch an artificial satellite into orbit around the Earth, on 4 October 1957. The Sputnik spacecraft, meaning 'companion' or 'fellow traveller', weighed 83kg and was about the size of a basketball. It orbited the Earth approximately every 98 minutes at a speed of 32,000km per hour, 800km above the earth. Sputnik was launched from Kazakhstan, and stayed in orbit for three months, plunging to Earth on 4 January 1958.

The successful Russian launch of the Sputnik 1 satellite in 1957 did effectively begin the "space race." Afterwards, the United States hurried to get a satellite into orbit. It also prompted John F. Kennedy to proclaim that the United States would be the first to get a man to the moon-- by the end of the 1960s.

The common translation is "traveling companion of the Earth".

When the satellite "Sputnik" was first launched in space in October of 1957, the New York Times gave the name's literal meaning as, "something that is traveling with a traveler" with the explanation, "the traveler is the earth, traveling through space, and the companion 'traveling with' it is the satellite."

Sputnik is Russian, and it means something like "travelling companion". It became the name for an early series of articifial satellites.

Sputnik was also scientifically valuable. The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave information about the ionosphere.

The launching of Sputnik by the Soviet Union led to increased fears of Soviet technological superiority and prompted the United States to invest more heavily in science and education. This event also led to the creation of NASA and sparked the Space Race between the two superpowers.

Sputnik was used for gathering data and information about space. It also led to the US/USSR space race. Seriously, Sputnik 1 sent out periodic radio beeps, that is ALL it did. It had no instruments for data collection of any kind! Most people think it was used for the USSR (the Soviet Union) to show other countries it was more technologically advanced than others.

The first dog to travel to space aboard Sputnik 2 on November 3, 1957, was named Laika. She was a Soviet space dog and became the first living creature to orbit Earth. Tragically, Laika did not survive the mission.

The name "Sputnik" comes from the Russian word for satellite, as the spacecraft was the first artificial satellite to be launched into space by the Soviet Union in 1957. The word "Sputnik" also means "companion" or "fellow traveler" in Russian.

Dwight D. Eisenhower was the President when the Soviet Union launched Sputnik on October 4, 1957.

The first satellite from Earth is named Sputnik 1, launched by the Soviet Union on October 4, 1957.

Laika is Russian - literally - for "barker"!!

The Soviet Union launched a dog named "Laika" into space aboard the Sputnik 2 space capsule.

Laika is also the name for a type of hunting dog. There are three breeds - the Russian European Laika, the East Siberian Laika and the West Siberian Laika. Note that Laika, the dog that went to space, is in fact a mongrel.

The space probe that has taken detailed photos of Mercury is the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft. It orbited Mercury from 2011 to 2015 and provided valuable insights into the planet's surface and composition.

Sputnik 2 was a Russian satellite that was launched into orbit. It carried a dog and crashed into Earthâ??s atmosphere.
