If you want these parts to fulfill contracts on satellites you need to place "NSS_MM_ContractsSatelliteScience.cfg" in GameData
ATTENTION! Stock parts ( except the survey scanner) won't work for those contracts anymore, only NSS' parts will. 
So copy this file only once you unlocked all the parts. 
Also please note that it will only work for contracts generated after you placed it GameData and launched the game. 
Previously generated contract will still require stock parts.
