A laser hit the tiny black cube, and it lurched forward almost at once. That split-second jump, caught during a zero-gravity ...

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 ...

The experiment also showed that tuning the light beam controlled the propulsion—the stronger the laser, the greater the ...

Phase Four, a best in class provider of electric radio frequency (RF) thrusters for in-space propulsion Phase Four, the creator of the radio-frequency thruster (RF thruster) for satellite propulsion, ...

A European consortium is developing miniaturized in space propulsion devices that operate without propellants. They are based on electrodynamic tether technology integrating perovskite-copper indium ...

For more than a century, gravity has been the immovable backdrop of modern physics, a force that can be described and exploited but never truly switched off. Now a former NASA engineer says he has ...

Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one problem—such a device would defy the laws of ...

Scientists show laser light can push graphene in space, opening the door to fuel-free movement and control of future ...

NASA engineers have successfully tested a new breed of reaction control engine and propulsion system. Aimed at furthering NASA’s space exploration goals, the tests helped investigate the possibility ...

Space is unforgiving about inefficiency. Every kilogram launched costs somewhere between $2,000 and $10,000 depending on the vehicle – and that’s on a good day with a favorable contract. In that ...

Delray Beach, FL, Oct. 20, 2025 (GLOBE NEWSWIRE) -- The space propulsion market was valued at USD 13.36 billion in 2025 and is projected to grow to USD 20.02 billion at a compound annual growth rate ...
