The Innovation:
Solar Photothermal Thrust

Our Solar Photothermal Thruster uses a photothermal absorber (graphene-based absorber) to efficiently convert sunlight into localized heat that drives interfacial photothermal evaporation, producing propellant mass flow and thrust in a compact form factor. The result is a propulsion approach designed to be highly efficient at turning watts into milli-Newtons, supporting fast maneuvers without requiring large power systems

Why it matters
  • More thrust per watt: optimized for maneuver rate and mission agility at CubeSat power levels

  • Operational simplicity: water as a working fluid supports safer handling and simplified logistics compared with many conventional propellants

  • Compact “maneuver package” path: architecture designed to integrate as a subsystem with clear interfaces (power, command/telemetry, thermal, plume keep-outs)

  • Scalable platform: a development path from CubeSat propulsion “beachhead” to broader smallsat maneuver and disposal applications
