So what your saying is that, I have to send Kerbals up and down from Kerbin, to the Mun and whatnot, have them walk or float around, do the report thing, and I'll level up? Do you have to level up to unlock the R&D Center? When I click transmit data with my EVA or with a Science Part, it transmits the data, but then I get a message saying, It would be helpful if the Research and Development Center was open?
