The biggest achievement of mankind has been recorded on 21st July 1969 when the Neil Armstrong became the first human being to step on the moon. This was the biggest breakthrough in the world of engineering and modern sciences because it gave us the courage to try new things. It made possible for humans to have faith in their experiments and dream for newer and bigger things that could be done on this planet and the others too in our galaxy. The day is recorded in the history as the tensest day all over the world, Neil Armstrong’s rocket had landed on the moon and he was preparing to step outside. Nearly after twenty minutes of opening the hatch he stepped on the surface of the moon and there was escalation of joyous congratulations all over the globe. People not only in the United States were happy about it, but the news spread like wildfire all over the globe and people were embracing the news of breaking a barrier with the help of science.

Today in the year 2013 there are plans to achieve a bigger goal. The plans to not only put a step on the planet Mars is in question, but scientists are planning to develop a human colony on it. New designs of rockets are being prepared which would be able to complete the trip successfully. The images sent by the Mars Rover have lifted the spirits of our scientists and they are hopeful soon the dream of building a human colony on the red planet would be a reality.

Sending the Rover was not an easy task and gave many challenges to the scientists. Since the gravity of the Red Planet is much more than the Moon, upon entering its atmosphere the pressure on the rocket would be multiplied many times. This could easily burst open the hatch covers and blow apart the entire rocket. Upon testing the tightness of hatch with ultrasound under many different pressure levels allowed the final design to be brought to light.

But that was designed for a machine, with humans inside the rocket things would be a lot different. Too much pressure on the body can burst the veins and muscles of the humans present inside. This called for a whole new design which would not only be able to keep the rocket intact, but it would also be needed to keep the human bodies’ safe inside. NASA is conducting hundreds of hatch cover ultrasonic tightness testing every day under different circumstances in its close to reality labs. It is believed that it would not be long before we get the good news of a rocket made fit for humans to travel. Then we will witness a whole new era where humans would be living on two different planets.
