Along with his followers, the German Hermann Oberth and the American Robert H. Goddard, he is considered to be one of the founding fathers of rocketry and astronautics.

However, it is more fuel-efficient for a craft to burn its fuel as close to the ground as possible ; see Oberth effect and reference.

" Oberth criticized the German system of education, saying " Our educational system is like an automobile which has strong rear lights, brightly illuminating the past.

For example, in an article in The American Weekly magazine of October 24, 1954, Oberth stated, " It is my thesis that flying saucers are real, and that they are space ships from another solar system.

Hermann Oberth is memorialized by the Hermann Oberth Space Travel Museum in Feucht, Germany, and by the Hermann Oberth Society.

The Oberth effect, in which a rocket engine when traveling at high speed generates more useful energy than one at traveling at low speed, is named after him.

* In the 1920s, Hermann Oberth described a method in which the rocket is assembled vertically on a floating barge, which he used in the movie Frau im Mond.

Although Oberth is often credited as the main technical consultant to the film, Ley's role was of central importance.

The trophy is named after the late founder of ASTRA, Oscar Swiglehoffer, who was also a personal friend and student of Hermann Oberth, one of the founding fathers of rocketry.

Another effect is the Oberth effect-this can be used to greatly decrease the delta-v needed, as using propellant at low potential energy / high speed multiplies the effect of a burn.

In astronautics, the Oberth effect is where the use of a rocket engine when travelling at high speed generates much more useful energy than one at low speed.

Oberth effect occurs because the propellant has more usable energy ( due to its kinetic energy on top of its chemical potential energy ) and it turns out that the vehicle is able to employ this kinetic energy to generate more mechanical power.

It is named after Hermann Oberth, the Austro-Hungarian-born, German physicist and a founder of modern rocketry, who apparently first described the effect.

Oberth effect is used in a powered flyby or Oberth maneuver where the application of an impulse, typically from the use of a rocket engine, close to a gravitational body ( where the gravity potential is low, and the speed is high ) can give much more change in kinetic energy and final speed ( i. e. higher specific energy ) than the same impulse applied further from the body for the same initial orbit.

For the Oberth effect to be most effective, the vehicle must be able to generate as much impulse as possible at the lowest possible altitude ; thus the Oberth effect is often far less useful for low-thrust reaction engines such as ion drives, which have a low propellant flow rate.

Nearby craters of note include Tikhov, which is nearly attached to the southeast rim, Oberth to the west, and Schjellerup to the north-northwest.

Space stations were also later envisaged by Konstantin Tsiolkovsky and Hermann Oberth.

In parts of 1928 and 1929, Oberth also worked in Berlin, Germany as a scientific consultant on the first film ever to have scenes set in outer space, Frau im Mond (" The Woman in the Moon "), which was directed and produced by the great film pioneer Fritz Lang at the Universum Film AG company.

Around the end of World War II in Europe in May 1945, the Oberth family moved to the town of Feucht, near Nuremberg, Germany, which became part of the American Zone of occupied Germany, and also the location of the high-level war-crimes trials of the surviving Nazi leaders.

He also began corresponding with every known rocket enthusiast in Europe, including Oberth himself.

He also joined Germany's amateur rocket movement, the Verein für Raumschiffahrt ( VfR-" Society for Space Travel ") which was centered on Oberth.

Oberth effect also can be used to understand the behaviour of multi-stage rockets ; the upper stage can generate much more usable kinetic energy than might be expected from simply considering the chemical energy of the propellants it carries.

Hermann Oberth was also a native Romanian, born in Sibiu.

The last moments of the series depict Elric on board a train on his way to meet Oberth, determined to study rocketry with him.

In this episode, Elric has heard of a great scientist, named " Oberth ", with curious theories ( The English dub explicitly states his name and research into rocketry ).

The mecha anime series The Super Dimension Fortress Macross from the early eighties featured a type of military spacecraft used by the U. N. Spacy Earth forces called the Oberth Class Space Destroyer.

Fullmetal Alchemist the Movie: Conqueror of Shamballa features Hermann Oberth as the " teacher " of the movie's protagonist, Edward Elric.

In 1923, Hermann Oberth ( 1894 – 1989 ) published Die Rakete zu den Planetenräumen (" The Rocket into Planetary Space "), a version of his doctoral thesis, after the University of Munich rejected it.

High-pressure pumps for larger missiles had been discussed by rocket pioneers such as Hermann Oberth.

Starting in 1930, he attended the Technical University of Berlin, where he assisted Oberth in liquid-fueled rocket motor tests.

This paper was highly influential on Hermann Oberth and Wernher Von Braun, later key players in spaceflight.

His concepts were first taken seriously only by the amateur rocketry movement in Germany, the Verein für Raumschiffahrt ( VfR-" Spaceflight Society "), centered on Hermann Oberth and his co-workers.

Hermann Julius Oberth ( 25 June 1894 – 28 December 1989 ) was an Austro-Hungarian-born German physicist and engineer.

By his own account and that of many others, around the age of 11 years old, Oberth became fascinated with the field in which he was to make his mark through reading the writings of Jules Verne, especially From the Earth to the Moon and Around the Moon, re-reading them to the point of memorization.

Influenced by Verne's books and ideas, Oberth constructed his first model rocket as a school student at the age of 14.

In 1912, Oberth began the study of medicine in Munich, Germany, but at the outbreak of World War I, he was drafted into the Imperial German Army, assigned to an infantry battalion, and sent to the Eastern Front against Russia.

On July 6, 1918, Oberth married Mathilde Hummel, with whom he had four children.

In 1919, Oberth once again moved to Germany, this time to study physics, initially in Munich and later in Göttingen.

Oberth commented later that he made the deliberate choice not to write another doctoral dissertation.

" Hermann Oberth was finally awarded his doctorate in physics with the same rocketry paper that he had written before, by the University, Cluj, Romania, under professor Augustin Maior, on May 23, 1923.

Oberth became a member of the Verein für Raumschiffahrt ( VfR )-the " Spaceflight Society " – an amateur rocketry group that had taken great inspiration from his book, and Oberth acted as something of a mentor to the enthusiasts who joined the Society.

Oberth lacked the opportunities to work or to teach at the college or university level, as did many well-educated experts in the physical sciences and engineering in the time period of the 1920s through the 1930s – with the situation becoming much worse during the worldwide Great Depression that started in 1929.

Therefore, from 1924 through 1938, Oberth supported himself and his family by teaching physics and mathematics at the Stephan Ludwig Roth High School in Mediaş, Romania.
