Why SpaceProp Strategies?

Developing, qualifying, and operating spaceflight hardware is undeniably difficult and expensive. Electric propulsion adds a unique layer of complexity that demands deep, specialized experience. SpaceProp Strategies, Inc. was founded to give programs of all sizes access to that expertise — efficiently and cost-effectively.

Our objective is simple:

Enable your team to navigate EP development and integration challenges so you can focus on what matters most — mission success.

Senior Experts.

Mission Focus.

No Fluff.

WHAT WE DO

Electric propulsion systems are among the most technically demanding subsystems on any spacecraft. From thruster heads and cathodes to power processing units (PPUs) to propellant management assemblies (PMAs) — the design, integration, and operational challenges are unique and often have an incredibly limited tolerance for risk or failure.

SpaceProp Strategies, Inc. specializes in:

  • EP System Design & Analysis — Architecture trades, performance modeling, and propellant budgeting for electric propulsion systems

  • Hardware Development & Qualification — Supporting EP system development programs from breadboard through flight qualification

  • Spacecraft Integration — Managing the unique electrical, mechanical, and thermal integration challenges that EP systems face

  • Launch & On-Orbit Operations — Pre-launch readiness reviews, commissioning support, and in-orbit anomaly resolution

  • Independent Technical Review — Objective, expert assessment of EP subsystem designs, test plans, and program risks

Why Electric

Propulsion?

Today’s space missions demand increasingly higher delta-V capability, enhanced on-orbit maneuverability, and lower (usually launch-mass-driven) costs. These often conflicting requirements coalesce to a singular enabling spacecraft technology:

Electric Propulsion.

Conceived in the 1960’s and first flown in the 1970’s, EP uses a combination of electricity and magnetism to ionize & accelerate a propellant to generate thrust. While the force generated by EP devices is low (on the scale of milli-Newtons to Newtons) and consequently necessitates more time to complete a given mission, the fuel efficiency is roughly 10x that of chemical propulsion (corresponding to a ~90% reduction in required propellant mass for a given mission). Further, EP applies long-duration adjustable thrust rather than short-duration impulsive thrust, the latter of which can compromise a mission if done on an incorrect trajectory or if critical timing is missed. EP therefore enables use of smaller & lighter spacecraft which are less costly to launch and provide a wider breadth of maneuvering capabilities on-orbit when in compared to chemical propulsion.

EP is now widely available in the commercial market and is employed on a multitude of operational & in-work missions. It is a flight-proven technology, but one with only a relatively small number of true subject matter experts (SMEs) worldwide.
