Thanks for this amazing mod, ethernet!! I haven't launched a Spectrometron yet, but I always assumed that soil sample analysis was a separate experiment, instead of merely short-cutting return of the soil sample to Kerbin. The way that you've explained it above, it seems contradictory to (my perception of) Station Science. All of the Experiment modules require return to Kerbin, so why not just save my soil samples in the return capsule and get 100% science upon arrival? (Instead of hauling an addition 10 (?) ton Spectrometron out to wherever.) If you were to change the Spectrometron such that its analysis was a different experiment from returning soil sample to Kerbin, IMHO it could add to game play. Assuming that Spectrometron "consumes" a soil sample, this gives players the following choices for each biome/soil sample: 1) Return the sample to Kerbin, same as stock game. 2) Spectometron analysis, transmit results (for faster science). 3) Player can collect two samples from a biome to do both of above, but this requires them to make two trips or bring two separate capsules, since (as far as I'm aware) a capsule can only store a single soil sample for each biome.
