The Nano electrokinetic thruster is a theoretical space propulsion system based on the principle of electro-osmosis (also electroosmotic flow). It allows for a high specific impulse and high thrust -to-power ratio as well as a high final velocity which makes it suitable for a wide variety of applications. Due to difficulties in the production ...
The Direct Fusion Drive (DFD) is a theoretical spacecraft propulsion system that derives its name from its unique capability to generate thrust directly from nuclear fusion, bypassing the need for an intermediate electricity-generating process. Using a magnetic confinement and heating mechanism, the DFD is powered by a blend of helium-3 (3He ...
A fusion rocket is a theoretical design for a rocket driven by fusion propulsion that could provide efficient and sustained acceleration in space without the need to carry a large fuel supply. The design requires fusion power technology beyond current capabilities, and much larger and more complex rockets. Fusion nuclear pulse propulsion is one ...
The Alcubierre metric defines the warp-drive spacetime. It is a Lorentzian manifold that, if interpreted in the context of general relativity, allows a warp bubble to appear in previously flat spacetime and move away at effectively faster-than-light speed. The interior of the bubble is an inertial reference frame and inhabitants experience no ...
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 ...
t. e. Non-rocket spacelaunch refers to theoretical concepts for launch into space where much of the speed and altitude needed to achieve orbit is provided by a propulsion technique that is not subject to the limits of the rocket equation. [1] Although all space launches to date have been rockets, a number of alternatives to rockets have been ...
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 ...
NASA artist rendering, from 1999, of the Project Orion pulsed nuclear fission spacecraft. Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, [1] and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft. [2][3] Early ...
