| Definition |
Safeguarding Earth’s biosphere and other planetary bodies from microbial contamination during space missions. |
| Objective |
Prevent contamination of Earth’s environment and other planets by alien microbes or Earth-origin microorganisms. |
| Legal Basis |
Article IX of Outer Space Treaty (1967) mandates avoiding harmful contamination in space exploration. |
| Importance |
- Protects integrity of scientific research on other planets.
- Prevents potential biological threats to Earth.
|
| Methods of Implementation |
- Spacecraft sterilization (e.g. baking in a dry room at 120°C for 3 days).
- Planning missions to avoid cross-contamination.
|
| Key Applications |
Missions to Mars, Moon, Europa and other celestial bodies where contamination may disrupt research or pose risks. |
| Challenges |
Increased costs and technical demands for maintaining sterile spacecraft and environments. |
| Recent Example |
China’s Tianwen-3 Mars sample-return mission (2028) confirmed adherence to planetary protection principles. |
| Global Cooperation |
International space agencies follow planetary protection guidelines for sustainable and safe space exploration. |
