Takeaway 1
Dr. Jayant Narlikar's 'An Alien Hand', the celebrated title story of the BSEB Class 7 English supplementary reader, is a brilliant work of hard science fiction exploring perspective inversion, planetary ecology, and dramatic irony. The narrative is set on the planet Mars, where a young boy named Tilloo lives with his family in an advanced subterranean colony. Generations earlier, Martians lived freely on the surface, but subtle changes in the sun thinned the atmosphere and plunged the planet into sub-zero desolation, driving all flora and fauna to extinction. Only humanoids survived by building underground habitats powered by automated solar energy stations on the surface.

Tilloo is consumed by curiosity regarding the upward-sloping tunnel his father takes daily to work on the surface. Seizing the opportunity during his father's afternoon nap, Tilloo steals his security pass, opens the sealed metal door, and ventures into the forbidden tunnel. However, automated infrared surveillance cameras photograph him, and security guards promptly escort him home. Rather than scolding him, Tilloo's father explains the lethal realities of the Martian surface: lack of oxygen, freezing cold, and the necessity of specialized space suits, oxygen packs, and surface boots.

The following day, Tilloo accompanies his father to the Central Control Room, where radar screens detect two alien spacecraft heading toward Mars. The President convenes an emergency meeting of the Council of Three: Number One (Defence) warns that destroying the craft would reveal their presence; Number Two (Scientist) observes that the craft is entirely unmanned; and Number Three (Social Scientist) urges total concealment. The President decrees strict non-interference.

Spacecraft 1 touches down on the surface, and an articulated robotic arm—the 'alien hand'—emerges to scoop up Martian soil. Fascinated by a prominent, shiny red button on the control dashboard, Tilloo succumbs to an irresistible childish urge and presses it. Alarms blare, and his father angrily pulls him back with a sharp slap. However, the momentary electrical jamming paralyzes the mechanical arm on the surface, causing it to freeze mid-air. Millions of miles away on Earth, NASA holds a televised press conference in Pasadena, acknowledging a mechanical glitch with the Viking lander. Technicians successfully beam radio repair commands, the mechanical hand resumes scooping soil, and NASA officially announces to the world: 'There are no signs of life on Mars.' The supreme dramatic irony leaves the reader smiling: Earth believes Mars is a dead planet, while the underground Martian civilization breathes a collective sigh of relief, remaining peacefully hidden from alien discovery.
