Now, I actually like that the repeated transmissions take time and energy to perform and transmit. For the interplanetary probe I sent to tour Jool and it's moons, it made it quite difficult to manage my high/low orbit scans during short windows of time (not enough dV to circularise anywhere, just gravity assisting around the system) and needing to make sure I was on the light side of every body to do them. It would have felt grindy if it wasn't so tense. But that was a probe with just thermometer, gravity and barometer (for the, ahem, 'landing' on Jool). All sensors that just need to transmit their readings. What I'd like to change is to basically not get the ability to transmit Goo, Science Jr or Surface Samples. If those three needed to be returned to be worth a damn, I'd find planning return trips a lot more rewarding. Just my opinion, but I think making that tweak would give probes a niche (don't have the tech/patience for a return trip? easier ((lighter)) to send a probe than a manned ship), and give you good reasons to make return trips. That's the low maintenance mod that I think could be made with just a few lines of code removed (hopefully just cutting off the ability for certain parts to transmit). My more advanced fantasy is to make the Science Jr part heavier (so most small landers couldnt have multiples), and then have a Hitchhikercan-like part that can store experiments. Basically so that it becomes more appealing to plan an Apollo style mission where my landers actually detatch from the orbiter, land on the surface, then return to the orbiter. On Mun, with it's half dozen biomes, this could mean landing the same orbiter in multiple craters during the same mission. Last thought: Oh! Maybe the larger command pods can carry more samples? Just to have a reason to use them. I did all the time in .21, but I've never used anything heavier than the mk1 in career mode.
