The laws of physics may not apply in the Star Wars universe. But just because it's highly unlikely we'll ever make the jump ...

Spacecraft rocket engines come in a variety of forms and use a variety of fuels, but most rely on chemical reactions to blast propellants out of a nozzle, with the reaction force driving the ...

Unlike most interplanetary probes, Dawn is not propelled by a chemical rocket engine, but by a solar-electric ion propulsion system, particularly suitable for long-distance flights. This innovative ...

Engineers are exploring propulsion methods that could enable longer-distance travel ...

Electric (plasma) propulsion devices have been used for applications such as station-keeping and orbit transfer, in place of chemical rockets, because they provide a higher specific impulse. Detailed ...

Letara, a startup that develops and manufactures propulsion systems (engines) for spacecraft such as satellites using plastic as fuel, announced on the 12th that it has raised an additional 650 ...
