Flying a thrust-vectoring rocket can be a challenge, and even more so if you stack multiple stages and a minimalist flight computer on top of it all. But [Joe Barnard] is not one to shy away from ...

On the latest attempt with a brand-new thrust vectoring Scout E rocket, he has gotten tantalizingly close to doing a controlled propulsive landing with a solid-fuel rocket motor. We’ve all been ...

This high thrust allows the rocket to accelerate faster. These systems also have a high specific impulse. Specific impulse measures how efficiently the propellant is used to generate thrust.

Zubrin also had a design for interplanetary propulsion called the Nuclear Salt Water Rocket. A nuclear salt-water ... providing the engine was directed to thrust perpendicular to the radial vector ...
