ALICE has been proposed as a propellant well-suited for on-site production on outer space bodies such as the Moon, as both aluminum oxide (a source of aluminum) and water are abundant resources in the universe, while the high propellant density decreases the dry mass of the rocket. Maintaining the propellant in a frozen state is relatively ...
The first, shared with solid rocket motors, is that the casing around the fuel grain must be built to withstand full combustion pressure and often extreme temperatures as well. However, modern composite structures handle this problem well, and when used with nitrous oxide and a solid rubber propellant (HTPB), relatively small percentage of fuel ...
Rocket candy, or R-Candy, is a type of rocket propellant for model rockets made with a form of sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the (optional) additive(s). In the past, sucrose was most commonly used as fuel.
How To Make My 5-Ingredient Energy Balls. For 12 balls, you’ll need: 1 cup (4 ounces) rolled oats. 3/4 cup (7 ounces) creamy peanut or almond butter
The highest levels of the chemical were found in popular baby and kid foods, which can lead to thyroid hormone issues, the report found.
Perchlorate, a chemical found in rocket fuel, has contaminated water and food and is more likely to be found in food given to babies and children, a study from Consumer Reports found.
On June 23, 2013, Copenhagen Suborbitals launched the SAPPHIRE-1 rocket with active guidance. This rocket reached an altitude of 8.2 km with a horizontal error/drift of 180 m at apogee with respect to the launch platform. This launch was also a potential first in amateur rocketry as the first guided rocket launched by amateurs.
The rocket, developed by United Launch Alliance, uses the Blue Origin's BE-4 engine, though the second stage uses the hydrolox RL10. New Glenn successfully reached orbit on its first try on 16 January 2025. The rocket and its engines are developed by Blue Origin. The first stage uses BE-4 engines, and the second stage uses the hydrolox BE-3U.
