Episode notes
Monte Carlo Exposes Compound Uncertainty
- Monte Carlo quantifies how uncertainties compound across a mission model by sampling combinations of uncertain parameters.
- It reveals the distribution of possible outcomes so teams can measure how bad things might get.
Start With Launch Dispersion Bounds
- Treat launch vehicle drop-off position and velocity as primary uncertain inputs in your simulations.
- Request the provider's error bounds early so mission design can be planned around realistic margins.
Sunlight Can Steer Your Spacecraft
- Solar radiation pressure matters even for small spacecraft because reflectivity and orientation change the continuous force.
- Surface coatings and thermal properties significantly affect trajectory nudges over time.
