Could we maybe sell excess science to an Earth company for money; a small but useful amount so that you aren't sitting on giant piles of science near the end of the game with nothing to do with it...
Pretty much a reverse version of the science purchasing you can do with the lab boys in the tutorial... Obviously the science you sell would be way cheaper than the science you can buy (for obvious balancing reasons), but it puts some of that excess science to use when you really have no other use for it... Or when you need an emergency cashflow option...
