History of spaceflight
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first animal, the first human and the first woman into orbit. The United States landed the first men on the Moon in 1969. Through the late 20th century, France, the United Kingdom, Japan, and China were also working on projects to reach space.
Following the end of the Space Race, spaceflight has been characterized by greater international cooperation, cheaper access to low Earth orbit and an expansion of commercial ventures. Interplanetary probes have visited all of the planets in the Solar System, and humans have remained in orbit for long periods aboard space stations such as Mir and the ISS. Most recently, China has emerged as the third nation with the capability to launch independent crewed missions, while operators in the commercial sector have developed reusable booster systems and craft launched from airborne platforms. In 2020, SpaceX became the first commercial operator to successfully launch a crewed mission to the International Space Station with Crew Dragon Demo-2.
At the beginning of the 20th century, there was a burst of scientific investigation into interplanetary travel, inspired by fiction by writers such as Jules Verne (From the Earth to the Moon, Around the Moon) and H.G. Wells (The First Men in the Moon, The War of the Worlds).[citation needed]
The first realistic proposal for spaceflight was "Issledovanie Mirovikh Prostranstv Reaktivnimi Priborami", or "The Exploration of Cosmic Space by Means of Reaction Devices" by Konstantin Tsiolkovsky, published in 1903.
Spaceflight became an engineering possibility with the work of Robert H. Goddard's publication in 1919 of his paper "A Method of Reaching Extreme Altitudes", where his application of the de Laval nozzle to liquid fuel rockets gave sufficient power for interplanetary travel to become possible. This paper was highly influential on Hermann Oberth and Wernher von Braun, later key players in spaceflight.[citation needed]
In 1929, the Slovene officer Hermann Noordung was the first to imagine a complete space station in his book The Problem of Space Travel.
The first rocket to reach space was the German V-2 rocket MW 18014, on a vertical test flight in June 1944. After the war ended, the research and development branch of the (British) Ordinance Office organised Operation Backfire which, in October 1945, assembled enough V-2 missiles and supporting components to enable the launch of three (possibly four, depending on source consulted) of them from a site near Cuxhaven in northern Germany. Although these launches were inclined and the rockets did not achieve the altitude necessary to be regarded as sub-orbital spaceflight, the Backfire report remains the most extensive technical documentation of the rocket, including all support procedures, tailored vehicles and fuel composition.
Subsequently, the British Interplanetary Society proposed an enlarged man-carrying version of the V-2 called Megaroc. The plan, written in 1946, envisaged a three-year development programme culminating in the launch of test pilot Eric Brown on a sub-orbital mission in 1949. The decision by the Ministry of Supply under Attlee's government to concentrate on nuclear power generation and sub-sonic passenger jet aircraft delayed the UK's space research.
