Quick question about science of 0.22. I've been playing KSP for a long time, but I hate math (I know, I know, I'm playing the wrong game) and I was hoping to pawn the work off . So my question is it more efficient to do multiple trips to do an experiment and return and recover every time or is it just as efficient to transmit back to Kerbin, given an essentially unlimited supply of electric charge with solar panels? For example, say I'm doing the goo experiment over the Mun. Is it just as acceptable to repeatedly beam it back to Kerbin on a communatron, or should I run up a bunch of rockets, do the experiment, keep it, and run them back to Kerbin 20 (or more ) times?
