This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Nuclear rockets are the future of space propulsion, and while fission propulsion is rapidly developing, most believe fusion propulsion is still a ways off. However, a new U.K.-based company is ...

Notably, Moonwatt’s system is being built around sodium-ion cells for the batteries that will store the solar energy. The technology offers an enticing alternative to lithium-ion since ...

The work, which was completed with the RTX Technology Research Center, marks another step forward for this novel propulsion concept, which offers high thermal efficiency and performance in a ...

Guy is a Senior Editor for Aviation Week, covering technology and propulsion. He is based in Colorado Springs. Robinson Unveils New Large R88 Rotorcraft is available to both Aviation Week & Space ...

And while batteries themselves aren’t some new technology, the lithium-ion (Li-on) kind that powers most of our devices only began gaining ground a few short decades ago. But just as the world ...

Ion channels are integral membrane protein assemblies that modulate the flow of ions into and out of a cell or organelle, leading to generation of electrical signals. Opening (gating) of ion ...

Dr. Charles Buhler, a veteran NASA engineer and co-founder of Exodus Propulsion Technologies, has revealed a startling breakthrough. His team’s propellantless propulsion drive has successfully ...

We are making highly efficient engines even more powerful and researching future propulsion solutions for climate-neutral aviation and power plant turbines for an environmentally friendly energy ...

Along with that, he used a capacitor multiplier circuit and diodes to boost the voltage. His dedication to building this ion thruster is truly impressive, but like previous versions, it still produces ...

They would roughly double the efficiency of traditional chemical rockets while delivering much higher thrust than ion propulsion systems. Cutting down travel time is an incredibly important goal ...
