American interest in " gravity control propulsion research " intensified during the early 1950s. Literature from that period used the terms anti-gravity, anti-gravitation, baricentric, counterbary, electrogravitics (eGrav), G-projects, gravitics, gravity control, and gravity propulsion. [1][2] Their publicized goals were to discover and develop ...
The Breakthrough Propulsion Physics Project (BPP) was a research project funded by NASA from 1996 to 2002 to study various proposals for revolutionary methods of spacecraft propulsion that would require breakthroughs in physics before they could be realized. [1][2] The project ended in 2002, when the Advanced Space Transportation Program was ...
Artistic depiction of a fictional anti-gravity vehicle. Anti-gravity (also known as non-gravitational field) is a hypothetical phenomenon of creating a place or object that is free from the force of gravity. It does not refer to either the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with ...
Ning Li (physicist) Ning Li (Chinese: 李宁, pinyin: Lǐ Níng; January 14, 1943 – July 27, 2021) was a Chinese American scientist. Born in Shandong, she graduated from the Department of Physics of Peking University, and in 1983 she emigrated with her family from China to the United States. [1] She is known for her physics and anti-gravity ...
Spacecraft propulsion. A remote camera captures a close-up view of an RS-25 during a test firing at the John C. Stennis Space Center in Hancock County, Mississippi. Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of ...
Martin Tajmar. Martin Tajmar. (2010) Martin Tajmar is a physicist and professor for Space Systems at the Dresden University of Technology. [1] He has research interests in advanced space propulsion systems, FEEP thrusters, breakthrough propulsion physics and possible connections between gravity and superconductivity. [2]
The Advanced Propulsion Physics Laboratory is enabled by section 2.3.7 of the NASA Technology Roadmap TA 2: In Space Propulsion Technologies: [11] Breakthrough Propulsion: Breakthrough propulsion is an area of technology development that seeks to explore and develop a deeper understanding of the nature of space-time, gravitation, inertial frames, quantum vacuum, and other fundamental physical ...
All designs for electromagnetic propulsion operate on the principle of reaction mass. A hypothetical drive which did not expel propellant in order to produce a reaction force, providing thrust while being a closed system with no external interaction, would be a reactionless drive, violating the conservation of momentum and Newton's third law.
