To what extent has Earth’s gravity shaped our cognitive and brain functions? Utilizing spaceflight and a ground-based analog, a new study shows that the human brain relies on bodily gravitational ...

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 ...

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 ...

When economist Roger Babson was a boy, his oldest sister drowned. His grandson would later die in a similar manner. As an adult, Babson would use the considerable wealth he made predicting the 1929 ...

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 ...
