How can i send data to MPL to research it. Sometimes a button appears just below the "Keep Data" buton called "Process in Lab Module" but sometimes don't And i couldn't figure out when that button appears I read some articles which saying that it button appears when the vessel connected to MPL but i transmitted data to MPL from far away using antenna (from Sun orbit to Kerbin orbit) What is the matter when that button appears ? Thanks In Advance
