This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

[Markus Bindhammer] worked out a way to make solid rocket propellant from newspaper. Judging from the test footage after the break the home made engines work great! There isn’t a long list of ...

[KoD] and [Navic] are building solid propellant motors using sugar and potassium nitrate. They cook up the two ingredients along with water and a bonding agent. They find that corn syrup is ...

In space flight, propellants based on hydrazines are used, among other things, as standard for attitude and control regulation in spacecraft. Like the oxidizer dinitrogen tetroxide (NTO) used for this ...
