Suggestion: Allow Kerbals to take small, medium or large soil sample. Storing a sample on-board increases the craft mass (small 1/2 ton, medium 2 tons and large 4 tons for example), creating a new set of challenges. Returning the sample to KSP adds a "trophy" in the form of a rock (of the colour and style of the collected planet) at the KSP. The small sample would be a small rock and have a bronze plaque (detailing the planet/moon of origin and date retrieved), the medium would be medium sized with a silver plaque and the large gold.
