An engineer who once worked with NASA says he has built a machine that can push against gravity without burning a drop of fuel, a claim that, if true, would upend how rockets, satellites, and even ...

European researchers are developing miniaturized space propulsion technology that is propellant-free and based on electrodynamic tethers integrating perovskite-copper indium gallium diselenide (CIGS) ...

British engineer Roger Shawyer introduced the EmDrive in 2001, claiming it could produce thrust without propellant, but rigorous testing by 2021 found no evidence it actually worked as advertised.

NASA plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip. This ...

A laser hit the tiny black cube, and it lurched forward almost at once. That split-second jump, caught during a zero-gravity arc aboard a parabolic flight, points to a strange and promising idea for ...

Humanity’s plans for deep-space exploration hinge on the ability to use basic resources, such as water, to propel rockets to farther destinations in the solar system. Despite decades of ...

There are also advantages over hybrid propulsion systems which have multiple propulsion modes but each use a separate propellant. "I can choose to use high-thrust at any time and low-thrust at any ...
