ION-X is a propulsion company developing ionic-liquid thrusters for the fast-growing small satellites segment. Their technology provides twice the current state-of-the-art performances in terms of thrust (Thrust >1mN) and fuel efficiency (ISP>5000s for 1U thruster). They are currently in negotiation for an in-orbit demonstration mission by the end of 2023 with significant commercial interests from European small satellite manufacturers such as Endurosat and Hemeria.
