Propulsion
Engine cycles, feed systems, pressurization, and ground/flight test plans with CFD/FEM-backed iteration.
Slipstream
An open program to design a modular starship and orbital dockyard—propulsion, structures, avionics, GNC, thermal, power, life support, and payload.
Mission
Build an openly verifiable spaceflight stack. Specifications, CAD, simulation models, tests, and flight results are public by design.
- Open designs under permissive licensing
- Interfaces first: versioned subsystem contracts
- Validated sims, reproducible rigs, real test data
- Safety culture, documentation, and peer review
Subsystems
Avionics
Radiation-tolerant computing, deterministic buses, and flight software you can build locally.
Structures
Mass‑efficient primary/secondary structure with manufacturability constraints and open tooling.
GNC
Actuators, sensors, filters, and guidance modes with HIL benches and public logs.
Thermal & Power
Thermal control, TPS, and power generation/storage with clear derating and margins.
Life Support & Payload
Closed‑loop ECLSS options and adaptable payload interfaces for research and ops.
Governance
Slipstream uses a merit‑driven, review‑heavy model. Work is tracked in public repos with RFCs, issues, and milestones.
- RFCs for major changes
- Codeowners & subsystem leads
- Design reviews & test readiness reviews
- Safety board & incident postmortems
Roadmap
- Phase 0 Website & Docs Ship site, define org, safety, and contribution playbooks.
- Phase 1 Interfaces & Baselines Subsystem contracts, CAD/sim seeds, test plans.
- Phase 2 Bench & Rig Tests Electronics, propulsion subscale, materials, thermal.
- Phase 3 Flight Articles Prototype integration, telemetry, open data.
