A day in a spacecraft

I found myself at the space research centre. I was asked to go for a training session by an officer where I was dressed as an astronaut and had to listen to a whole lot of instructions. The officer then led me to a place where there was a huge rocket. I was amazed at its gigantic size. I was then asked to enter the cockpit along with the rest of the crew. I soon realized that I was the captain of the spaceship. In a moment the final countdown began and soon the rocket jet propelled into the air towards outer space. I was on an expedition to the Mars.

Soon the rocket left the earth's atmosphere and I was feeling light as ever. I realized that there was less gravity than on the earth. It was a great experience to find myself floating in the air. But the conditions inside the shuttle were so adjusted that we could ground ourselves at will. It was a magnificent sight to view our planet earth from space. The earth looked blue because of three-fourth being water. As we moved on we could see the moon that looked like a planet itself, but reflected the light of the sun. We kept moving ahead and could see many stars located very far from us. I was already some light years away. As we moved on I could see several other galaxies at a distance. I wondered if life existed on those planets. I also saw some meteors pass us by. The Asteroid belt could be seen from a distance as well. Soon I saw our shuttle reaching the planet Mars. It was 'red' just as I had studied in the books and it was beyond description. I did not have the words to express it. The space shuttle was about to land and my attention focused on the surface of the Mars. There was some kind of a storm on the planet. I was wondering whether I would meet the first speck of life on Mars…. when suddenly I heard someone reminding me - It's time to wake up, time to get ready for school!

Well! That was the end of my exciting sojourn. For a moment I thought I had already become an astronaut flying in space. That journey into space in my dream will always be memorable.
