A new concept for an advanced “Dual-Stage 4-Grid” (DS4G) ion thruster has been proposed and tested. It is able to operate at very high specific impulse, power and thrust density values.
An alternative novel mission concept has been recently conceived based on conductive tethers providing both power and propulsion at Jupiter to allow a cost-effective tour of the Jovian system including rendezvous with the moons Io and Europa.
High-density plasma is produced by the use of a helical radio frequency antenna to ionise neutral gas in a tube closed at one end. The helical antenna excites the gas to dissociate electrons and generate highly energetic ions.
The exploration of the solar system requires advanced propulsion techniques capable of high specific impulse and high specific power. Fusion is the most interesting option to meet these requirements.
Mission concepts exploiting advanced propulsion currently under internal study within ACT. Mission and system design are optimised according to particular mission requirements (e.g. minimum transfer time).
Is it possible to reduce the dimensions of propulsion systems to chip size? The combination of MEMS, Nanotechnology discipliens together with a Propulsion point of view are taken as starting point for innovative systems.
Recent trends in the space community for smaller, cheaper and more frequent space missions are driving the development of nano- and pico-spacecraft, which are considered for large constellations or swarm formations.
