Hi, why does everyone act as if we had unlimited time? Mankind is overdue, it's just a matter of time until a comet hits earth or other unexpected things happen. In the meantime, scientists are making efforts to find earthlike exoplanets. And with all the respect for their work and achievements, where is the point in eventually finding such a planet one day, when it's several hunderd lightyears away? I'm not afraid of being extinced in my lifetime, but I wonder why mankind appears so little ambitious making it into space. Why are we sending one rover after another to mars, instead of sending some bacterial cultures and see how they perform and how eligible they appear for the purpose of terraforming. I'm approaching this a little naive, of course, but the point stays the same: Why are things going so slowly?
