Meanwhile, solid rocket engines are simple ... as the 3D printed casing of one of [Integza’s] liquid-fuelled rockets continued burning once the fuel was turned off. This prompted the realization ...

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 ...

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 ...

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 ...

For nearly a year, SpaceX has been trying out something new: super-cooling the liquid oxygen (LOX) which is a key ingredient in rocket fuel. It's called deep-cryo LOX, and the idea has been around ...
