Warp drive is said to be the holy grail of space exploration and possesses the capability of faster than light speed travel.

NASA engineer, David Burns, produced an engine concept that, he says, could theoretically accelerate to 99 percent of the speed of light.

When it comes to space, there's a problem with our human drive to go all the places and see all things. A big problem. It's, well, space.

Researchers develop a totally new type of fuel that has projected energy density greater than the most advanced heavy-duty fuels used today.

A research team from Japan has investigated the viability of using such microwave-powered propulsion for real-world applications.

This form of propulsion starts with large solar arrays that convert sunlight into electricity, providing the power source for the spacecraft

Underwater vehicles are typically designed for one cruise speed, and they’re often inefficient at other speeds.
