In a groundbreaking development, scientists have engineered a revolutionary engine that utilizes the cold of space to generate power. This innovative device, operating without traditional fuels, draws ...

From plasma engines that could turn months of travel into weeks to the first blueprints for ships that will outlive their ...

Over 14,000 pieces of junk are clogging up low Earth orbit, but this number could be reduced by a new invention that involves a satellite using the plasma exhaust of its ion engine to knock dangerous ...

The reusability of different parts of a space rocket has opened the doors to a literal flood of launches to Earth orbit and beyond. Thanks to the fact that space companies now no longer have to make a ...

This engine won't be fueling interstellar missions, but still finds an unexpected way to use deep space energy to generate power. Reading time 3 minutes Deep space may provide hidden sources of energy ...

Here’s what you’ll learn when you read this story: Stirling engines, which have been around for centuries, leverage temperature differentials in a gas to do light mechanical work. A new study ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

A countdown is underway at NASA's Florida spaceport, ticking down the days until the public can experience a rocket engine test closer than ever before — by standing directly under the engine's nozzle ...
