Have you ever wondered how far into space we could go? Well I have and it’s not that far. Unless NASA can come up with a extensive fuel tank; find a person who is willing to travel for around 19 years ( forward and back from the furthest planet, Pluto) then I don’t think we’re going to find anything more than what we have already. I don't mean to be pesamistic but, we have been travelling to space for years; if we were going to travel to mars we would have done it a little while ago. Besides do we really need to go further into space, or are we just nosy and want to risk the lives of others (astronauts) just to satisfy the needs of our knowledge. It definitely is important to learn but at the cost of another...It's just not worth it.
