Episode notes
Spacecraft Mission Modes Explained
- Spacecraft operate in distinct mission modes analogous to a car's modes like parking or driving.
- Each mode defines power consumption, system state, and behaviors crucial to mission success without redo opportunities.
Load Shed Mode Is "Oh Shit Mode"
- Load shed mode is the lowest, safest mode focusing on preserving spacecraft life by minimal operation.
- It is essentially the "Oh Shit Mode" intended to recover from faults and keep communication alive.
Role of Safe Mode in Spacecraft
- Safe mode stabilizes the spacecraft and ensures power and communication are maintained.
- From safe mode, spacecraft either proceed to cruise (thrust) mode or earth comms mode depending on mission needs.
