People often ask why we should bother exploring space. For example, why should we bother to send a rover to mars, why search for alien planets, why land on an asteroid, why bother going to Pluto? People say that it costs too much. They say that it’s too dangerous. They say that there are a million reasons that we shouldn’t explore space.
And I think that the latest comic from Zen Pencil puts all of this into perspective. And it’s terribly relevant. Of course, there are many reason to explore space (and to explore in general). But I think that this answers the question rather eloquently.
But if you want the hard facts, here is NASA tech that invades your everyday life. See a larger image here.
