A former NASA engineer claims a new engine can beat gravity without fuel. Is it a breakthrough or just a classic physics trap?

Phase Four tested its Maxwell engine with water propellant. The U.S. Air Force Research Laboratory's green propellant, Advanced Spacecraft Energetic Non-Toxic, contains a significant percentage of ...

WASHINGTON — The idea that rocket propellants could be made from lunar ice is not new. But the U.S. government should now consider doing that at scale in order to stimulate the space economy and ...

Electric solid propellants are being explored as a safer option for pyrotechnics, mining, and in-space propulsion because they only ignite with an electric current. But because all of these ...

Nitrous oxide’s high-speed abilities don’t end with racing cars, as it’s a powerful enough oxidizer to be a practical component of rocket propellant. Since [Markus Bindhammer] is building a hybrid ...

Developing new propellants for satellites to replace toxic hydrazine would make launching and handling satellites safer but it also requires disrupting current systems, according to researchers. As ...

Procter & Gamble has patented an aerosol package design utilizing adsorbent materials to maintain pressure, acting as propellants. The package includes a bag, can, and valve with an adsorption matrix ...

Imagine you’re driving to work on a rainy day, when a distracted, reckless driver hits your car out of nowhere. With a “boom,” an air bag deploys faster than you can blink your eyes to save your life.
