All rockets used some form of solid or powdered propellant up until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Solid rockets are still used ...

[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 ...

But the twentieth-century saw a technological explosion of new rocket-propulsion systems, using both solid and liquid propellants. Rocket-powered vehicles were developed for two primary purposes: ...

Boron-based solid propellants are gaining attention in the field of energetic materials due to their high energy density and potential applications in rocket propulsion and explosives. Boron ...

Another promising development is the exploration of hydrogen peroxide as an oxidizer in solid rocket propellants. Traditionally, hydrogen peroxide has been limited to liquid propellants ...

A Chinese commercial space launch company is continuing its success with a small solid rocket ahead of a more ambitious launch later this year.

South Korea has also said it has secured “efficient and advanced” solid-propellant ballistic missile technology, though in much smaller rockets so far. Liquid propellants provide greater ...

In recent years, North Korea has been developing more missiles with built-in solid propellants. Such weapons are easier to move and hide, and can be launched quicker than liquid-propellant ...
