Bradford Space


Bradford Space develops technologies to export the NewSpace philosophy, and the increased value proposition it has already offered in LEO, to beyond LEO applications, such as GEO, lunar and interplanetary space. This accelerates the cadence of scientific exploration and enables new business uses in these frontiers.

We offer affordable and high-performance avionics whose robust and performing nature makes them well-suited for both deep space and demanding near Earth orbit applications.

We produce the Comet propulsion system which is a launch-safe and cost-effective electrothermal propulsion system offering the ideal balance of cost and performance. Comet uses water as propellant which allows it to be handled and fuelled at the factory with ease. Its highly flexible interface is easy to integrate into small satellites and to operate on orbit.   



An avionics solution – a modular system suitable for deep-space or high-performance smallsats in the 30-300kg (dry) mass range with a 5+ year lifetime, consisting of any combination of:

  • robust flight computer
  • high performance computational platform (with full-scale OS)
  • power control and distribution unit (that supports high-power loads such as electric propulsion, radar payload or drive motors)
  • high-power radio transponder with navigational ranging that works out to 1AU
  • propulsion electrical control unit aimed at monopropellant thruster solutions 

The Comet – a water-based propulsion system for small LEO spacecraft

  • Non-toxic, safe for humans and launch vehicles
  • More thrust with less electrical power
  • Highly-flexible interface suitable for a wide range of spacecraft sizes
  • Zero failure in-orbit 
  • Space heritage since 2018
