Excuse a seemingly dark attitude, but apparently, as I rehearse my thoughts before I type them, I see the universe, outside of earth, as a bit of a prison. You’ll typically find me watching any sci-fi film I can get my hands on. I love all the fantasy and dream of what it would be like to be doing what they “do”. But outside of a few more robotic rover missions on Mars, or perhaps some deeper, visual space exploration from something like Hubble’s cousin, I don’t see anything more magnificent happening.
We have passed through one of the Van Allen belts by sheer speed, which basically consists of two enormous belts of radiation which surround the earth. They are very dangerous, if not deadly, to circuits, equipment, humans and other delicate matter. Being completely shielded by them apparently requires an immense thickness of lead and complex layers of other substances, so much so that it would be too bulky and weight deficient to have within a rocket for lift off. This being another prison door which is open to pass through, yet we have no key for.
Going back to our present means of interstellar thrust, rocket fuel, we don’t have the capability to move fast enough or sustain life long enough, to venture very far at all. Even if we were able to put humans on Mars, for example, there’s no telling what could go wrong to get them back. There are no fix it shops out there, the ships have typically no free space for spare parts, and we’d be riding around with a couple of fingers crossed and a bald spare tire.
Again, I am all for what we have done and what we are still trying to do, but sadly, I just feel that for many generations to come, we will just have to appreciate the universe from afar, and be content with the fact that we’re not going to be getting any closer any time soon.
This is exactly the thought I was trying to convey in my post as well. I commend the space missions that have already been completed but have we reached a point where there are just too many obstacles and too much expense. I know that humans have a natural urge to explore, we are a race of nomads since the beginning of time, but do we continue to spend billions of dollars to reach further just to prove we can. The thought of being able to live on another planet is what some people see as the ultimate achievement for the human race, what I think is, that our ultimate achievement would be taking care of the planet we already live on so leaving it does not have to become an option.
