While the subject matter may sound like science fiction, authors Marc Millis and Eric Davis point out that a growing number of reputable scientific journals are discussing such topics, although at ...

For decades, scientists have dismissed the idea of reactionless propulsion—the concept of generating thrust without expelling propellant—as a fantasy that defies the laws of physics. But Charles ...

Controlling gravity will probably never help us launch a spacecraft, but that does not mean we should give up on the idea, says the European Space Agency. It is calling for missions that might one day ...

World’s largest electric propulsion pointing mechanism will enable Aerojet AEPS Thrusters on the Maxar-built Power and Propulsion Element (PPE) of NASA’s lunar space station. The Gateway space station ...

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 ...

Exploration of small bodies, namely comets and asteroids remain a challenging endeavor due to their low gravity. The risk is so high that missions such as Hayabusa II and OSIRIS-REx will be performing ...
