It seems to me that the purpose of a rover is to be able to visit multiple biomes on a celestial body and bring back science from those locations. To that end, I suggest that you add a new part: The RovCo Rover Science Storage Box Model III - adapted from the finest recycled fishing tackle boxes. With it you can store not one, not two, but THREE of each science data type. No more running back to the lander with every pebble you pick up! Storage of graviton readings, temperatures and even seismic readouts are a snap! The RSSB III is the answer to your mobile data storage needs! Expanded versions of the RSSB are under development. The RSSB Model V is expected to store five of each type of reading and the capacious Model X will store 10, more than you'll ever likely use! --- A smaller RCS storage device, similar to the ROUND-8 Toroidal Fuel Tank, would be nice for small rovers and micro sats. Some similarly small control jets would be welcome as well, especially ones designed to help keep your rover firmly on the planet/moon it's exploring. In case anyone from MechJeb reads this: It would also be nice if MechJeb were to introduce a more compact version of their marvelous tool that can easily be tucked away in space-limited rover and micro-sat designs. It would also be nice to add a way to transfer science from one ship to another when the two are docked. Having to do a spacewalk every time gets old after a while. Thanks!
