The idea surfaced again in Jules Verne's The Begum's Fortune (1879). In 1903, Konstantin Tsiolkovsky (1857–1935) published Exploring Space Using Jet Propulsion Devices, which is the first academic treatise on the use of rocketry to launch spacecraft.
He calculated the orbital speed required for a minimal orbit, and that a multi-stage rocket fueled by liquid propellants could achieve this. In 1928, Herman Potočnik (1892–1929) published his sole book, The Problem of Space Travel – The Rocket Motor.
He described the use of orbiting spacecraft for observation of the ground and described how the special conditions of space could be useful for scientific experiments. In a 1945 Wireless World article, the English science fiction writer Arthur C.
Project RAND eventually released the report, but considered the satellite to be a tool for science, politics, and propaganda, rather than a potential military weapon. In 1946, American theoretical astrophysicist Lyman Spitzer proposed an orbiting space telescope. In February 1954 Project RAND released "Scientific Uses for a Satellite Vehicle", written by R.R.

This expanded on potential scientific uses for satellite vehicles and was followed in June 1955 with "The Scientific Use of an Artificial Satellite", by H.K.
Kellogg. In the context of activities planned for the International Geophysical Year (1957–58), the White House announced on 29 July 1955 that the U.S.
The unanticipated announcement of Sputnik 1's success precipitated the Sputnik crisis in the United States and ignited the so-called Space Race within the Cold War. Sputnik 2 was launched on 3 November 1957 and carried the first living passenger into orbit, a dog named Laika. In early 1955, following pressure by the American Rocket Society, the National Science Foundation, and the International Geophysical Year, the Army and Navy were working on Project Orbiter with two competing programs.
These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon. On 4 October 1957, the Soviet Union launched the world's first artificial satellite, Sputnik 1.
On 31 July, the Soviets announced that they intended to launch a satellite by the fall of 1957. The first artificial satellite was Sputnik 1, launched by the Soviet Union on 4 October 1957 under the Sputnik program, with Sergei Korolev as chief designer.

intended to launch satellites by the spring of 1958.
Explorer 1 became the United States' first artificial satellite on 31 January 1958. In June 1961, three-and-a-half years after the launch of Sputnik 1, the United States Space Surveillance Network cataloged 115 Earth-orbiting satellites. Early satellites were constructed to unique designs.

According to a 2018 estimate, about 5,000 remained in orbit.
