Water-based plasma thrusters could power spacecraft for deep space missions

A research team at the University of Bologna is developing a new space propulsion system called Water-based Electric Thrusters (WET). This technology converts water into plasma to generate thrust for spacecraft. WET thrusters operate on 500-1000 watts, making them ideal for small satellites with limited power. The system could enable in-space refueling and longer missions by using water as fuel, potentially obtained from celestial bodies. This environmentally friendly approach may revolutionize space exploration by making it more sustainable and accessible.
