Scientists and engineers are diligently working on innovative concepts to make the next era of human spaceflight more powerful and more efficient using nuclear propulsion. One of these designs, known ...

NASA’s Space Launch System (SLS) is ready to fly with its four shuttle-era engines. The rocket, outfitted with the RS-25 ...

In the 1950s, the U.S. began focusing on nuclear propulsion as an effective way to power space exploration with projects ...

Significant uranium loss could reduce the engine’s specific impulse by up to two-thirds. The researchers propose using dielectrophoresis (DEP) to capture vaporized uranium, targeting a 99% ...

This week an in-space propulsion company, Impulse Space, announced that it had raised a significant amount of money, $300 million. This follows a fundraising round just last year in which the Southern ...

This engine is the vacuum-optimized engine that is used in the rocket's second stage. The Rutherford engine uses RP-1 (a type of refined, rocket-grade kerosene) and liquid oxygen (LOX) as the ...

The engine demonstrates enhanced thrust performance (at least 6 Newtons) and specific impulse (at least 100 kilometres per second). The project is part of a comprehensive programme focused on ...

With this system, the researchers estimate they could achieve a specific impulse of around 1500 seconds, almost double what a traditional NTP engine would have, while only having slightly less thrust.

Tech expert Kurt “CyberGuy" Knutsson says 329,000 mph fusion rocket promises to ... This engine powers their Sunbird ... The Sunbird boasts a high specific impulse and an integrated 2 MW ...

The benefits of a pulsed rocket engine versus a traditional rocket in space – aside from potential break-neck speeds of possibly 500,000 mph – are its hyper-efficiency, fine-tuned thrust ...

Thomas Mueller is an aerospace engineer known for his groundbreaking work in rocket engine design. Mueller was a founding employee of SpaceX and is currently the founder and CEO of Impulse Space.
