A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant.A propellantless drive is not necessarily reactionless when it constitutes an open system interacting with external fields; but a reactionless drive is a particular case of a propellantless drive that is a closed system, presumably in contradiction with the law of conservation of momentum.
Rogue Space Systems announced that the satellite is equipped with an "experimental propulsion" system, referred to as a "quantum drive," developed by IVO Limited. The satellite's testing program includes a 60-day resting period post-launch to stabilize its orbit, accounting for initial perturbations such as outgassing .
In the general relativistic field propulsion system space is considered to be an elastic field similar to rubber which means that space itself can be treated as an infinite elastic body. If the space-time curves, a normal inwards surface stress is generated which serves as a pressure field.
The Casimir effect was investigated experimentally and analytically under the Breakthrough Propulsion Physics project. This included the construction of MicroElectroMechanical (MEM) rectangular Casimir cavities. [3] [15] Theoretical work showed that the effect could be used to create net forces, although the forces would be extremely small.
The Advanced Electric Propulsion System qualification thruster inside one of the vacuum chambers at NASA Glenn’s Electric Propulsion and Power Laboratory. Advanced Electric Propulsion System ( AEPS ) is a solar electric propulsion system for spacecraft that is being designed, developed and tested by NASA and Aerojet Rocketdyne for large-scale ...
Magnetic sail animation. A magnetic sail is a proposed method of spacecraft propulsion where an onboard magnetic field source interacts with a plasma wind (e.g., the solar wind) to form an artificial magnetosphere (similar to Earth's magnetosphere) that acts as a sail, transferring force from the wind to the spacecraft requiring little to no propellant as detailed for each proposed magnetic ...
Field-emission electric propulsion (FEEP) is an advanced electrostatic space propulsion concept, a form of ion thruster, that uses a liquid metal as a propellant – usually either caesium, indium, or mercury. [1] A FEEP device consists of an emitter and an accelerator electrode.
Busek's BIT-3 ion thruster operating on several propellants. The propulsion maturation is a partnership between NASA and the U.S. Air Force. iSat's iodine propulsion system consists of a 200 watt Hall thruster (BHT-200-I) developed by Busek Co, a cathode, a tank to store solid iodine, a power processing unit (PPU) and the feed system to supply the iodine.
