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 ...

Boron is the fifth lightest element, has a high intrinsic energy density, and is cheap, abundant and stable — making it of interest as a solid rocket fuel and as an additive to jet fuels to ...

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 ...

Magdrive is working on three versions of its space thrusters, and because they run on solid metal, they might one day even be powered by space junk collected directly in orbit, turning it from threat ...

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 ...

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 ...
