Hermann Julius Oberth (German: [ˈhɛrman ˈjuːli̯ʊs ˈoːbɛrt]; 25 June 1894 – 28 December 1989) was an Austro-Hungarian -born German physicist and rocket pioneer of Transylvanian Saxon descent. [3] Oberth supported Nazi Germany 's war effort and received the War Merit Cross (1st Class) in 1943.
Propulsive maneuvers. v. t. e. In astronautics, a powered flyby, or Oberth maneuver, is a maneuver in which a spacecraft falls into a gravitational well and then uses its engines to further accelerate as it is falling, thereby achieving additional speed. [1] The resulting maneuver is a more efficient way to gain kinetic energy than applying the ...
Wege zur Raumschiffahrt (Ways to space travel) is a book by Hermann Oberth. Written in German, it was published in 1929 by the Munich Oldenbourg publishing house [1] and was considered a standard work in rocketry for a long time. It was - with a new title and completely revised - the 3rd edition of Oberth's first book Die Rakete zu den ...
Sun gun. The sun gun or heliobeam is a theoretical orbital weapon, which makes use of a concave mirror mounted on a satellite, to concentrate sunlight onto a small area at the Earth's surface, destroying targets or killing through heat.
t. e. 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. [a] The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun.
The Hermann Oberth Space Travel Museum (Hermann-Oberth-Raumfahrt-Museum, or Hermann-Oberth-Museum for short) is a museum of space technology in the Franconian city of Feucht in Bavaria, Germany. It commemorates the life work of the famous visionary and rocket pioneer Hermann Oberth. Exhibits include a Kumulus rocket and a Cirrus rocket, which ...
Space mirrors are satellites that are designed to change the amount of solar radiation that impacts the Earth as a form of climate engineering. The concept was first theorised in 1923 by physicist Hermann Oberth [1][2][3][4] and later developed in the 1980s by other scientists. [5] Space mirrors can be used to increase or decrease the amount of ...
The Hermann Oberth Gesellschaft (1952-1993) [3] was an association named after Hermann Oberth, [4] the German astronautics pioneer and the authoritative expert on rocketry outside the United States, [5] which develops and builds rockets and trains engineers in space technology. The association was founded on the initiative of the german rocket ...
