SPACE BIOGRAPHY: James A. Van Allen

van-allenJames A. Van Allen (1914 – 2006) was a pathbreaking astrophysicist best known for his work in magnetospheric physics. Van Allen graduated from Iowa Wesleyan College in 1935. He then enrolled at the University of Iowa where he received an M.S. in 1936 and a Ph.D. in 1939.

Following school, Van Allen accepted employment with the Department of Terrestrial Magnetism at the Carnegie Institution of Washington, where he studied photodisintegration. In April 1942 Van Allen moved to the Applied Physics Laboratory at the Johns Hopkins University where he worked to develop a rugged vacuum tube. He also helped to develop proximity fuzes for weapons used in the war, especially for anti-aircraft projectiles used by the U.S. Navy.

By the fall of 1942, he had been commissioned as an officer in the Navy and was sent to the Pacific to field test and complete operational requirements for the proximity fuzes. Upon completing his assignments in World War II, Van Allen returned to civilian life and began working in high altitude research, first for the Applied Physics Laboratory and, after 1950, at the University of Iowa.

Van Allen’s career took an important turn in 1955 when he and several other American scientists developed proposals for the launch of a scientific satellite as part of the research program conducted during the International Geophysical Year (IGY) of 1957-1958. After the success of the Soviet Union with Sputnik 1, Van Allen’s Explorer spacecraft was approved for launch on a Redstone rocket.

It flew on 31 January 1958, and returned enormously important scientific data about the radiation belts circling the Earth. Van Allen became a celebrity because of the success of that mission, and he went on to other important scientific projects in space. In one way or another, Van Allen was involved in the first four Explorer probes, the first Pioneers, several Mariner efforts, and the orbiting geophysical observatory.

James A. Van Allen retired from the University of Iowa in 1985 to become Carver Professor of Physics, Emeritus, after having served as the head of the Department of Physics and Astronomy from 1951.

James A. Van Allen passed away on August 9, 2006 at the age of 91.


SPACE BIOGRAPHY: Sergei Korolev

Sergei P. Korolev (1906-1966) was trained in aeronautical engineering at the Kiev Polytechnic Institute and, after receiving a secondary education, co-founded the Moscow rocketry organization GIRD (Gruppa Isutcheniya Reaktivnovo Dvisheniya, Group for Investigation of Reactive Motion).

Like the VfR (Verein fuer Raumschiiffahrt, Society for Spaceship Travel) in Germany, and Robert H. Goddard in the United States, the Russian organizations were by the early 1930s testing liquid-fueled rockets of increasing size. In Russia, GIRD lasted only two years before the military, seeing the potential of rockets, replaced it with the RNII (Reaction Propulsion Scientific Research Institute).

RNII developed a series of rocket-propelled missiles and gliders during the 1930s, culminating in Korolev’s RP-318, Russia’s first rocket propelled aircraft. Before the aircraft could make a rocket propelled flight, however, Korolev and other aerospace engineers were thrown into the Soviet prison system in 1937-1938 during the peak of Stalin’s purges.

Korolev at first spent months in transit on the Transsiberian railway and on a prison vessel at Magadan. This was followed by a year in the Kolyma gold mines, the most dreaded part of the Gulag. Stalin soon recognized the importance of aeronautical engineers in preparing for the impending war with Hitler, however, and retrieved from incarceration Korolev and other technical personnel that could help the Red Army by developing new weapons. A system of sharashkas (prison design bureaus) was set up to exploit the jailed talent.

Korolev was saved by the intervention of senior aircraft designer Sergei Tupolev, himself a prisoner, who requested his services in the TsKB-39 sharashka. Following the war, Korolev was released from prison and appointed Chief Constructor for development of a long-range ballistic missile. By 1 April 1953, as Korolev was preparing for the first launch of the R-11 rocket, he received approval from the Council of Ministers for development of the world’s first intercontinental ballistic missile (ICBM), the R-7. To concentrate on development of the R-7, Korolev’s other projects were spun off to a new design bureau in Dnepropetrovsk headed by Korolev’s assistant, Mikhail Kuzmich Yangel. This was the first of several design bureaus, some later competing with Korolev’s, that would spinoff once Korolev had perfected a new technology.

It was Korolev’s R-7 ICBM that launched Sputnik 1 on 4 October 1957. This launch served to galvanize American concern about the capability of the Soviet Union to attack the United States with nuclear weapons using ballistic missiles. During the early 1960s, Korolev campaigned to send a Soviet cosmonaut to the Moon.

Following the initial reconnaissance of the Moon by Lunas 1, 2, and 3, Korolev established three largely independent efforts aimed at achieving a Soviet lunar landing before the Americans. The first objective, met by Vostok and Voskhod, was to prove that human space flight was possible.

The second objective was to develop lunar vehicles which would soft-land on the Moon’s surface to insure that a cosmonaut would not sink into the dust accumulated by four billion years of meteorite impacts.

The third objective, and the most difficult to achieve, was to develop a huge booster to send cosmonauts to the Moon. His design bureau began work on the N-1 launch vehicle, a counterpart to the American Saturn V, beginning in 1962. This rocket was to be capable of launching a maximum of 110,000 pounds into low-Earth orbit.

Although the project continued until 1971 before cancellation, the N-1 never made a successful flight.

On 14 January 1966 Sergei P. Korolev died from a botched hemorrhoid operation.
