The future of the Human Species - Part 4: Will we create our future?Written by K.A.Cassimally
Experiments have shown that human physiology becomes very weak in an unknown environment to brain. Humans then start to panic. Problem is that humans do not necessarily want to show their uncertainty. So they hide it. When they actually hide this uncertainty, humans start to get stressed and this is big problem.
When we get stressed, we become moody and cannot concentrate on what we are doing. Imagine an astronaut getting really frustrated in middle of a mission on International Space Station. This may be catastrophic! He seizes a hammer floating nearby in zero-gravity of space and demolishes ISS’s main computer. The whole crew will be in a most-probably-fatal danger. No doubt guilty astronaut will realise consequence of his action afterwards but it will be too late.
Trained astronauts themselves, have big difficulties adapting to a space mission of up to two months. Think of a manned mission to Mars. This journey takes a minimum of two years to accomplish plus there is return journey too. Humans will have to live in shuttle conditions with no privacy for four years that is 1461 days (1 more day from a leap year included). You will agree with me that it is hard to make a journey of this many days properly. Bear in mind that a journey of only 60 days seems difficult. What should we do then?
We presently have technology to go to Mars. The problem lies with persons who are going to board on shuttle. Many scientists have concluded that humans like us will have much difficulty in overcoming stress and frustration. But humans unlike us may be able to do it! Imagine a human being with 4 arms instead of 2 (the 2 additional arms take places of 2 legs). He will be able to crawl everywhere on a shuttle like a spider. This spider human will specialise himself in this field. I am not joking! Scientists say that they can create a human with 4 arms and no legs.
The future of the Human Species - Part 2:Where next?Written by K.A.Cassimally
Many scientists are currently exploring idea of going to live on Mars. Mars is nearest planet to Earth and scientists actually think that red planet resembled our Earth some million years ago. Some other scientists from NASA Ames Center have already started creation of a ‘Mars town’ and many others are in fact already experimenting it. Of course, these experiments are done on Earth itself but this ‘Mars town’ has an environment practically alike to that of Mars. And perfect place for conduction of this experiment is in Texas, USA.
The astronauts working in these towns wear their space suit and also do everything they would really have to carry out if they ever go to Mars in future.
But Mars would be, like Earth a temporary place for humans. When Sun starts engulfing planets, Mars will disappear barely hours after earth. So Mars only seems to be ideal place to spread human species. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster, I mean asteroid collision and things like that.
If we, humans do not want to disappear when earth or mars get swallowed up, we will have to go and live beyond solar system. But are there any planets outside our solar system prepared to support life? Astronomers’ answer is: “If Earth can support life, why can’t other planets do same too? Astronomers have already discovered a Jupiter-like planet orbiting a Sun-like star so why not an Earth-like planet orbiting a Sun-like star next?” Astronomers clearly think that, yes, there has to be other planets alike to Earth waiting to be colonised out there. And maybe, these planets will in future hold our species.
