    CompanyExoCube | Propulsion without propellant tanks

    ExoSat · Supports System

    “ExoCube is a self-contained propulsion module that fits within a fraction of a CubeSat unit. Inside: a compact pulsed laser, a beam-steering scanner and a solid ablation plate. Each laser pulse vaporises a microscopic layer of the plate; the ejected material produces thrust.”

    CompanyExoTug | Propulsion as a service, fuelled by orbital debris

    ExoSat · Supports System

    “ExoTug # Propulsion as a service, fuelled by orbital debris. A servicing vehicle that docks with your satellite and moves it: to a higher orbit, out of the way of a conjunction, or down to re-entry, using debris as its propellant.”
