A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were ...

A new test of nuclear propellant fuel under space-like conditions has been hailed as a success by NASA and General Atomics ...

ISRO has successfully developed a 10-tonne propellant mixer for solid motors, marking a significant technological achievement ...

It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer. We’re already quite familiar with solid rocket propellant, but this hybrid approach is much ...

When a liquid-fuel rocket takes off, it can switch its gas jet from side to side, correcting any tendency to veer off course. But solid-fuel rockets have no separate combustion chamber ...

The trials verify that the fuel can survive the harsh environment of a nuclear rocket reactor. Up until now, the main way of propelling spacecraft has been through chemical rockets. To be fair ...

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 ...

Solid fuel dates back to fireworks developed by the Chinese centuries ago, but made dramatic progress in the mid-20th century, when the U.S. developed more powerful propellants.
