Study Notes
Space System Design Considerations
- A major consideration in the design of any space system is the space environment and its effects on the spacecraft.
Space Environment Factors
- The space environment includes all factors that can cause damage to a spacecraft, except for human error.
- The space environment factors that can cause damage to a spacecraft include radiation, extreme temperatures, meteoroids, and orbital debris.
Hazards of Spacecraft Electronics
- The hazards of spacecraft electronics are attributed to the total ionizing dose (TID) and single-event effects (SEEs).
Course Emphasis
- The course emphasizes the natural environmental factors and interactions that contribute to the hazards of spacecraft electronics.
Operational Anomalies and Satellite Failures
- A significant number of reported operational anomalies and satellite failures have been attributed to space radiation and single-event effects (SEEs).
