What We Do

Experience is not given, but earned.

We have worked fundamental mission concepts, performed concept-to-implementation EP system development, overseen spacecraft integration operations, and successfully resolved on-orbit anomalies.

We are therefore uniquely qualified to assist customers building & flying EP-based spacecraft.

ep system Development

On-orbit positioning is critical, which begins with the EP system. We have the knowhow to spearhead a novel EP thruster design or optimize an existing propulsion solution.

  • Fundamental & background research and system conceptualization

  • Requirements definitions to meet the mission needs

  • Component-level & integrated system design, planning, and architecture

  • Detailed design & prototype development guidance and support

  • Material selection & mass optimization for each subsystem element

SSI also provides COMPLET GROUND-UP ELECTRIC PROPULSION SUBSYSTEM DESIGN & DEVELOPMENT SERVCIES, including hardware production, hardware procurement, hardware sourcing, qualification test coordination & support, spacecraft integration coordination & support, and flight ops support.

Qualification & Acceptance Testing

The ability for space hardware to survive launch, space environments, and the full mission duration must be validated. Our extensive experience enables us to provide numerous related services.

  • Procedure & test plan generation and review

  • Facility buildup, equipment selection, & configuration optimization

  • Component-level testing planning & oversight

  • Environmental & lifetime qualification support

  • Hardware & test anomaly resolution & root-cause investigations

  • Test facility warm introductions

  • Test coordination & oversight, & post-test analyses

Spacecraft integration support

Space hardware is worthless without an integrated spacecraft system. Let us assist with your spacecraft-level integration workflow.

  • On-vehicle hardware placement optimization

  • Electrical & plumbing routing

  • Hardware installation sequencing

  • Spacecraft-level acceptance testing

  • Space environment considerations

  • Critical document (e.g., ICD, Test Report, Specification) review

Post-Launch support

You've made it to orbit, but your EP system is not operating nominally. Worse, failure to resolve the issue is threatening mission success.

What now?

SpaceProp Strategies has direct experience resolving mission-critical on-orbit anomalies associated with electric propulsion systems. Your mission is not over — let us get you back on trajectory.

  • On-orbit anomaly assessment and root-cause investigation

  • EP system operational state reconstruction and analysis

  • Contingency commanding strategy development

  • Coordination support with spacecraft bus and operations teams

  • Recovery plan development and implementation guidance
