 Before you read

Have you heard of the Viking Mission to Mars? The National Aeronautics and Space Administration’s (NASA) Viking Mission to Mars was composed of two spacecraft, Viking 1 and Viking 2, each consisting of an orbiter and a lander. The primary objectives were to obtain images and samples of the Martian surface and soil and search for any possible signs of life. Viking 1 was launched on 20 August 1975 and arrived at Mars on 19 June 1976. Viking 2 was launched on 9 September 1975 and entered Mars’ orbit on 7 August 1976. Besides taking photographs and collecting other science data on the Martian surface, the two landers conducted three biology experiments to look for possible signs of life. As of now, there is no clear evidence of the presence of living microorganisms in the soil near the landing sites. Now read the story.

An Alien Hand

“TILLOO! How often have you been told not to go that way?” “But why does Daddy go there every day?” “Because that’s his job, Tilloo!”

‘That way’ was an underground passage. Tilloo’s father went every day for work along that passage. And every day he came back from that direction. What lay at the end of that forbidden route? Not only Tilloo, but a great majority of the community would have liked to know. Tilloo’s father was one of the select few permitted to go that way. The above conversation invariably took place between Tilloo and his mother whenever he insisted on following his father. Today, however, was different. Tilloo’s father was enjoying a siesta at home and Tilloo managed to get hold of his security card. Then, evading his watchful mother’s eye, Tilloo made his way to the forbidden passage. A metal door barred his entry. But Tilloo had watched his father slip the magic card into a slot. He did the same... and the door opened noiselessly . A well-lit passage seemed to beckon him.

Snatching the card which had come out of another slot in the wall, Tilloo started his march along a gentle upward slope—for the passage led from the underground habitat to the surface of the planet. Tilloo looked forward to seeing the sun (if it was daytime) or the stars (if it was night) about which he had heard and read so much.

But alas, that wasn’t to be! Tilloo had underestimated the security arrangements. Invisible mechanical devices had already detected and photographed the small intruder, sent his picture to the Central Bureau where it was thoroughly checked... And before he had advanced ten paces a strong hand fell heavily on his shoulder. Gently but firmly he was escorted by the security staff back home to an anxious and angry mother. While he was being scolded he received help from an unexpected quarter.

“Let me explain to him, darling!” said his father who had just got up. “If he is properly briefed, he will not do such a thing again.” He started to explain. “Listen, Tilloo! I work on a surface where an ordinary person cannot survive because the air is too thin to breathe and where the temperature is so low that you would freeze to death.”

“But, Daddy, how do you manage to survive?” “Because I go well-equipped, in a special suit with a reservoir of oxygen. I can keep warm and my boots are specially designed to make it easy for me to walk on the surface. What’s more, I’ve been trained to survive and work on the surface.

“There was a time when our forefathers lived on the surface quite naturally. Indeed they did so for millions of years. But times changed. The very sun, which had provided us with sustenance, turned hostile. It changed only slightly but the change was sufficient to upset the balance of nature on this planet.
