Wow! what a bunch of great suggestions. I'd like to add that I think using the jr. science lab to analyze samples and transmit the results back would make sense (I'd like to see a rover with this capability). I think there should be a second pool of science points for sample returns (how else are the Kerbals going to get their pet Mun rocks). Different capsules could have different sample carrying capacities. I don't think we need a separate module for hard drives, once again different capsules could have different data storage capacities. As far as antennas go I think different antennas could have different science loss rates and ranges. This would give a reason to use different antennas for different missions. It would also make sense to use I high powered antenna if you only had to transmit the data once. One feature I haven't seen is science for space plane missions. I'd like to get a little bit of science for my first SSTO plane. I would love to say that I love .22 and have been addicted over the weekend. I've been a little saddened by the criticism I've read so far. Most of the issues people are complaining about are just game play balancing issues. For a first introduction to science I think .22 goes way beyond what I was expecting.
