re: Ok, here is an interesting analogy
It's gotta be a technology advance that is needed. If 30 years of rocketry hasn't put more than a few people in space, then we have to build more than just rockets. Space is a new hostile environment, and we're trying to conquer it. We can't just walk there. We need a vehicle, a device, a new tool. Ships were originally used to cross the oceans. What do we use today? Something completely different...
