It is. At the same time I am at least as impressed with the antique people that went all over the globe in leaky (and by modern standards tiny) buckets.

They all share the same drive to discover the unknown and it still saddens me that we stopped at the moon (though I understand how it happened). We could have been all over the solar system by now, the cost would be phenomenal and it would still be extremely dangerous but definitely a possibility if mankind would pull in the same direction for a while. I suspect we were/are at a local maximum of sorts that precludes that from happening and the attractor is strong enough that we may never be able to escape from it.
