Safer solid propellant for cubesats

Los Alamos National Laboratory has a radical new solid propellent for cubesats. Unlike a traditional composite propellant, which mechanically mixes a fuel and an oxidizer into a high explosive, the new propellant ignites an energetic fuel — really a low …

Progress to electrodeless plasma propulsion engine

Researchers from Tohoku University have been trying to find out how the plasma flow is influenced by its environment via laboratory experiments. They are making progress towards creating an electrodeless plasma thruster used to propel spacecraft. There are many methods …

Nuclear fusion pellet runway

Jordin Kare described his fusion pellet proposal in the 1990s. Pellets (with deuterium and tritium or other fusion gases) are laid down in an outbound track for the spacecraft that will eventually use them, deployed in advance by small spacecraft …
