There was a problem though; solid rocket motors are far too common to be interesting, and even hybrid rocket engines are becoming passé. We’ve never seen a liquid-fuel rocket build before ...

Solid-fuel rockets avoid most of this waste of energy by burning their fuel very fast—in a few seconds, if desirable. Instead of struggling painfully off the ground as liquid-fuel rockets do ...

This liquid rocket fuel becomes magnetised when near a magnetic field. So it dances and morphs when magnets are moved around it. It is called ferrofluid and it was invented by NASA's Steve Papell ...

That is more than four times as powerful as the liquid fuel engine on the Long ... mobility and near-instant launch capability, solid-fuel rockets are mainly used to deliver missiles or on other ...

This is not the only potential application, however. Because solid-fuel rockets are cheaper than liquid-fuel rockets, the new engine could drastically cut the cost of sending rockets into space, which ...

Solid-fuel rockets are cheaper than their liquid-fuel counterparts, meaning the new engine could significantly reduce spaceflight costs. This is particularly noteworthy given the growing number of ...

Rocket hybrid propulsion market is rapidly expanding, driven by military advancements, growing space tourism, and innovative ...

We’ve all been thrilled to see the SpaceX rockets return to earth, landing elegantly on a floating pad. But those are liquid-fueled. The trick with a solid-fuel rocket motor is it can’t be ...
