Hermann Oberth Society
The Hermann Oberth Society is an association named after Hermann Oberth, the German astronautics pioneer and the authoritative expert on rocketry outside the United States, which develops and builds rockets and trains engineers in space technology. The Society was established in 1952 by Karl Poggensee in Bremen as the German Agency For Affairs of Space Travel (DAFRA), tasked to develop civilian rockets. Early on in Hespenbusch, near Großenkneten, various prototype rockets were developed, which soon reached heights of a few kilometers. The available area in Hespenbusch quickly became too small to continue to conduct rocket tests there. In 1957 the rocket experiments of DAFRA, which was renamed the DRG (German rocket company), moved to Cuxhaven, where rocket tests were resumed in 1959. On December 15, 1960, the first launch of the Kumulus, which had a maximum height of 20 kilometres, took place and on September 16, 1961, the first launch of the Cirrus, which had a maximum height o ...

Nonprofit Organization
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a Profit (accounting), profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be Tax exemption, tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hermann Oberth
Hermann Julius Oberth (; 25 June 1894 – 28 December 1989) was an Austro-Hungarian-born German physicist and engineer. He is considered one of the founding fathers of rocketry and astronautics, along with Robert Esnault-Pelterie, Konstantin Tsiolkovsky, Robert Goddard and Herman Potočnik.During WWII he supported Nazi Germany's ''Aggregat'' rocket program. Early life Oberth was born to a Transylvanian Saxon family in Nagyszeben (Hermannstadt), Austrian-Hungary Empire (today Sibiu in Romania). He was fluent in Romanian language. At the age of 11 years, Oberth's interest in rocketry was set off by the novels of Jules Verne, especially ''From the Earth to the Moon'' and ''Around the Moon''. He was fond of reading them over and over until they were engraved in his memory. As a result, Oberth constructed his first model rocket as a school student at the age of 14. In his youthful experiments, he arrived independently at the concept of the multistage rocket. However, during this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rocket
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Space Technology
Space technology is technology for use in outer space, in travel (''astronautics'') or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation. Space technology includes space vehicles such as spacecraft, satellites, space stations and orbital launch vehicles; deep-space communication; in-space propulsion; and a wide variety of other technologies including support infrastructure equipment, and procedures. The space environment is a sufficiently novel environment that attempting to work in it often requires new tools and techniques. Many common everyday services for terrestrial use such as weather forecasting, remote sensing, satellite navigation systems, satellite television, and some long-distance communications systems critically rely on space infrastructure. Of the sciences, astronomy and Earth science benefit from space technology. New technologies originating with or accelerated by space-related endeavors are o ...
