Recommendations

1. Strong metadata policy

2. Increase and create more Micrometeoroly Instrumentation Labs

3. Adopt a minimal standard Post-field data quality control protocol

4. Net data transfer (reduce the problems time detection)

5. Contract more MsC and PhD - local Team

6. Support to a reserve equipments and replacement kits program

7. Create a data base to improve and optimize this program
