Sample interview questions: How do you approach the assessment and selection of propulsion technologies for space missions?
Sample answer:
Assessment and Selection of Propulsion Technologies for Space Missions
-
Mission Requirements Analysis:
- Determine mission objectives, payload mass, trajectory, and propellant mass requirements.
- Identify potential constraints (power consumption, weight, volume, lifetime).
-
Technology Evaluation:
- Research and evaluate available propulsion technologies (chemical, electric, nuclear).
- Assess performance characteristics (thrust, specific impulse, efficiency, reliability).
- Consider technology readiness levels and development timelines.
-
Comparative Analysis:
- Compare propulsion options based on performance, cost, and risk factors.
- Use performance models and simulations to predict system behavior.
- Consider trade-offs between different technologies (e.g., thrust vs. efficiency).
-
System-Level Considerations:
- Integrate propulsion system with spacecraft design and operations.
- Analyze potential interactions with other subsystems (… Read full answer
