That's science right there - all our best evidence indicates that this can be feasible, and this seems the least effort to try it. Nice plan to at least see how far we can get, before we have to revise and replan. We're testing just the principles we want to test, using established functionality where we aren't testing.
That's far more 'magical' to me, than promising another set of boots in places that won't be feasible without exactly these kinds of experiments happening first. More rovers - more measurements!
When we need to spend the big resources to send people off this gravity well, lets have it make sense, perhaps set up a semblance of an workable environment first. We can barely make earth-based closed etiologies last for long - it would be a sad excuse for a 'backup' with our current level of development. We absolutely CAN expand into the galaxy/universe - but we've still got a few mountains of puzzle pieces left unsorted still, in my particular opinion.
