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 ...

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: ...

[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 ...

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 ...

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 ...

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 ...
