3. **COSPAR Categories**: The Committee on Space Research (COSPAR) categorizes missions into five groups based on the type of celestial body and the mission type:
- **Category I**: Missions to locations not significant for chemical evolution or the origin of life (e.g., the Sun).
- **Category II**: Missions to locations with a remote chance of contamination affecting investigations (e.g., the Moon).
- **Category III**: Flyby and orbiter missions to locations with a significant chance of contamination (e.g., Mars, Europa, Enceladus).
- **Category IV**: Lander or probe missions to the same locations as Category III.
- **Category V**: Sample-return missions[2][3].
