Spaceflight Before 1951

Spaceflight as a practical endeavor began during World War II with the development of operational liquid-fueled rockets. Beginning life as a weapon, the V-2 was pressed into peaceful service after the war at the United States' White Sands Missile Range as well as the Soviet Union's Kapustin Yar. This led to a flourishing of missile designs setting the stage for the exploration of space. The small American WAC Corporal rocket was evolved into the Aerobee, a much more powerful sounding rocket. Exploration of space began in earnest in 1947 with the flight of the first Aerobee, 46 of which had flown by the end of 1950. These and other rockets, both Soviet and American, returned the first direct data on air density, temperature, charged particles and magnetic fields in the Earth's upper atmosphere.

By 1948, the United States Navy had evolved the V-2 design into the Viking capable of more than 100 miles (160 km) in altitude. The first Viking to accomplish this feat, number four, did so 10 May 1950. The Soviet Union developed a virtual copy of the V-2 called the R-1, which first flew in 1948. Its longer-ranged successor, the R-2, entered military service in 1950. This event marked the entry of both superpowers into the post-V-2 rocketry era.

Origins and rocket development

The era of spaceflight began in 1942 with the development of the V-2 rocket (A-4) as a ballistic missile by Germany, the first vehicle capable of reaching the 100 kilometres (62 mi) boundary of space (as defined by the World Air Sports Federation). On 20 June 1944, a V-2 (MW 18014) was launched vertically, reaching a height of 174.6 kilometres (108.5 mi).

The post-war years saw rapid development in rocket technology by both superpowers, jumpstarted by the dozens of V-2s and hundreds of German specialists that ended up in the custody of the Soviet Union and the United States. The V-2, designed for carrying a warhead horizontally rather than vertical science missions, made an inefficient sounding rocket, while the wartime American WAC Corporal sounding rocket was too small to carry much scientific equipment. In 1946, the US Navy began development of its own heavy sounding rocket, the Viking, derived in part from the V-2. The Aerobee was developed from the WAC Corporal to loft lighter payloads.

The Soviet Union began military development of the R-1, a copy of the V-2 with modifications intended to improve reliability, in 1947. Flight testing of this first Soviet-made liquid-fueled missile began on 13 September 1948, and the rocket entered military service in 1950. Also from 1947, two advanced rockets with ranges of 600 kilometres (370 mi), the German émigré-designed G-1 (or R-10) and the Russian-designed R-2, competed for limited engineering and production staff, the latter winning out by the end of 1949 and being put into service in 1951. The draft plan for the 3,000 kilometres (1,900 mi) range R-3 was approved on 7 December 1949, though it was never developed, later designs proving more useful and achievable.

Space exploration

V-2, WAC Corporal, and R-1A

The V-2s captured from Germany at the end of World War II were used for engineering and scientific missions by the United States and the Soviet Union. The first 25 captured V-2s were launched in the 15 months commencing 15 March 1946. By the end of 1950, more than 60 had been launched by the Americans, most of them equipped with research instruments. The first biological payloads launched to high altitude were sent on V-2s, starting with seeds and fruit flies in 1947, followed by mice and monkeys from 1948 onward.

The V-2 was also used in early experiments with two-stage rockets: Project Bumper combined the V-2 first stage with the WAC Corporal as second stage. On 24 February 1949, Bumper 5 set an altitude record of 417 kilometres (259 mi). Around 10 WAC Corporals were also launched on their own in this period.

The Soviet Union launched 11 captured V-2s in 1947. Three of the V-2s launched by the USSR in 1947 carried 500 kilograms (1,100 lb) experiment packages for measuring cosmic rays at high altitude; at least one returned usable data. Two Soviet R-1As (an experimental R-1 variant that tested nose cone separation at altitude) also carried scientific equipment during test launches in 1949, but neither returned usable data.

Aerobee

First launched on 24 November 1947, the solid/liquid-fuel hybrid Aerobee quickly secured a reputation for reliability. With the development of these first generation purpose-built sounding rockets, the exploration of Earth's upper atmosphere and the nearest reaches of space began in earnest, a total of 46 Aerobee flights being launched through 1950. Aerobee flights measured the velocity and density of cosmic rays above 70 miles (110 km) and made high altitude measurements of the Earth's magnetic field. Cameras mounted on Aerobee rockets returned the first high quality photographs from space of sizeable regions of the Earth as well as large scale cloud formations.

Viking

Vikings 1 and 2, launched in 1949 from White Sands Missile Range in New Mexico, both suffered from premature engine cutoff due to turbine leaks, significantly reducing their maximum altitude. The improved Viking 3, launched on 9 February 1950, reached 50 mi (80 km) and could have gone higher. However, after 34 seconds of accurately guided flight, the rocket veered westward and had to be destroyed by range safety.

On 10 May 1950, Viking 4 was launched from a site in the Pacific Ocean between Jarvis Island and Christmas Island. The fourth Viking became the first sounding rocket ever launched from a sea-going vessel, the USS Norton Sound. This flight was perfect, reaching 106.4 mi (171.2 km), more than double that reached by the earlier Vikings.

Viking 5, launched on 21 November 1950, carried a vast array of radiation detectors. The rocket also carried two movie cameras to take high altitude film of the Earth all the way to its peak height of 108 miles (174 km) as well as Pirani gauges to measure air densities in the upper atmosphere. Viking 6, launched on 11 December, underperformed, reaching a maximum altitude of 40 miles (64 km).
