Episode notes
Key Spacecraft Constraints
- Spacecraft must maintain communication, avoid extremes in temperature and power loss, and respect mass and fuel limits.
- These operational constraints significantly limit the feasible mission design space.
Electric Propulsion Constraints
- Low thrust electric propulsion changes trajectory design, limiting how quickly velocity can be altered despite high total delta V.
- It favors simplicity and speed over complex gravity assists common in traditional missions.
Challenge of Rideshare Launches
- Rideshare launches require planning thousands of trajectories daily to adapt to variable launch times and drop-off points.
- Modern computing enables rapid recalculation of trajectories previously not possible at this scale.
