Q1 Software
Control
Guidance, attitude control, allocation, safe modes, and runtime assurance keep commands inside the permitted envelope.
Universal reentry virtualization
Multiscale Space Systems
A software-first reusable orbital reentry platform for teams that need certifiable controls, diagnostics, simulation, and runtime safety across the full return corridor.
Altitude85 km
VelocityMach 20
VehicleBank corridor
Mission phase 3/7
Hypersonic Entry
The vehicle rides a controlled corridor through rapidly changing density while the software maintains margin against heat and load limits.
- Bank modulation
- Estimator fusion
- Safe envelope
Mission scopeReusable orbital return
Core postureSoftware-first
Primary layerControls + diagnostics
DeliverableCertifiable evidence
Four-quadrant architecture
A common software spine for very different return vehicles.
The platform treats reusable reentry as a repeating control problem. Hardware classes diverge in shape, sensors, actuators, and failure modes. The supervisory logic, estimator stack, digital twin, and evidence pipeline carry across.
- Bounded LearningLearned residuals can improve performance, but deterministic safety logic stays authoritative.
- Runtime AssuranceA verified baseline controller remains available whenever the predicted state approaches a limit.
- Reachable FootprintMission decisions are shaped by where the vehicle can safely go next, not only where it is now.
- Digital Twin EvidenceTelemetry, simulation, and verification artifacts converge into a reusable readiness record.
Q2 Hardware
Plant
Vehicle dynamics, aerothermal load, structural response, effectors, and recovery devices are represented as class-specific models.
Q4 Software
Estimators
Navigation filters, diagnostic observers, residual monitors, and fault classifiers turn measurements into trusted state knowledge.
Q3 Hardware
Sensors
IMU, satellite navigation, star tracking, air data, thermal sensing, strain, and altimetry feed the real-time belief state.
Engagement surface
Built for partners that already own the hard vehicle problem.
Multiscale Space Systems does not need to be the vehicle. The value is the reusable software, assurance, and evidence layer that lets vehicle programs move with more confidence.
For vehicle builders
Integrate a certifiable software layer around an owned capsule, lifting body, aeroshell, shield, parafoil, or stage.
For labs and agencies
Move from research-grade reentry concepts toward operational software with traceable safety arguments.
For commercial pilots
Focus early programs on bounded modules that create flight heritage and evidence without exposing proprietary vehicle data.
