Sputnik

Sputnik 1 was the world's first artificial satellite, launched by the Soviet Union in 1957. It was used to demonstrate the possibility of space travel, to study the Earth's atmosphere, and sparked the beginning of the space race between the United States and the Soviet Union.

Sputnik's successful launch by the Soviet Union in 1957 sparked concern in the US due to fears of Soviet technological superiority in the ongoing Cold War. This event triggered the Space Race and led to increased investment in science and education in the US.

The launch of Sputnik 1, the world's first artificial satellite, in 1957 was driven by the competition between the United States and the Soviet Union during the Cold War. The Soviet Union's successful launch demonstrated its technological advancement to the world, sparking fears in the United States and leading to increased investment in science, technology, and space exploration.

Sputnik was the name given to the first artificial Earth satellite, launched by the Soviet Union on October 4, 1957.

Sputnik 1 and the other space satellites were the cumination of an effort by the USSR to gain dominance in the use of Earth orbits. In addition to improving reconnaisance, navigation, and weather forecasting, satellites would yield valuable scientific data for military use (including the interaction of the Earth's magnetic field with communications transmission). During the Cold War with the US, each side sought an edge in technology, including space exploitation.
The principal scientific purpose for Sputnik was to study the density of the upper atmosphere.

Sputnik was the name of the first artificial satellite launched into space by the Soviet Union in 1957. It marked the beginning of the space age and the start of the space race between the United States and the Soviet Union.

Sputnik 1, the first artificial satellite, reached an altitude of about 939 kilometers (583 miles) above Earth's surface. This altitude allowed it to orbit the Earth approximately once every 96 minutes.

Sputnik 1 was a Soviet satellite that worked by emitting radio signals that could be tracked by ground stations. It transmitted a simple radio beep to indicate its position in orbit and played a significant role in the space race by being the first artificial satellite to orbit the Earth.

Sputnik was challenging to build due to the technological limitations at the time and the strict deadlines set by the Soviet government. The engineering team faced numerous technical obstacles, such as miniaturizing the components and ensuring the reliability of the launch vehicle. Despite these challenges, the team successfully launched Sputnik, marking a significant achievement in space exploration.

Sputnik-1 was launched by the Soviet Union in 1957 to become the world's first artificial satellite and to demonstrate the capabilities of sending objects into space and orbiting the Earth. It was primarily a scientific mission to study the density of the Earth's atmosphere and the ionosphere.

Sputnik 2 was sent into space to carry a living creature, Laika, a dog, as a test subject to explore the safety and feasibility of sending living organisms into space for future human spaceflights. It was also a demonstration of the Soviet Union's technological capabilities during the early space race.

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.
