Chapter 12
Chandrayaan
Let us read
There was a girl named Rani who lived in a village. She was very curious and used to ask many questions to her family, teachers and friends.
“Why is the sky blue?”
“Where does the Sun go at night?”
One evening, Rani heard her mother singing, “Chanda mama door ke ...” Hearing this, Rani asked her mother, “Amma, how far is the Moon?” Amma said, “Rani, the Moon is very far in the sky”.
Rani kept on thinking about the moon and fell asleep.
The next morning Rani woke up hearing the loud voice of her elder brother, Pratik. He was pointing to the TV and shouting in excitement, “Look Rani, India is on the Moon!”
Rani looked at the TV. She could see photos of some machines on the Moon. She heard a few people talking about the landing on the Moon. She was confused and asked Pratik, “How did Chandrayaan reach the Moon?”
Have you seen pictures of Chandrayaan landing on the moon?
Pratik replied that his friend Vivaan’s mother, Aunt Nandini, is a scientist. “Shall we go and talk to her?” asked Pratik. Rani happily agreed. Both Rani and Pratik decided to visit Vivaan’s house.
Vivaan and his mother welcomed them. Rani could see many models and photographs of rockets in their house.
Nandini Aunty offered sharbat to the children and said, “Rani, what do you want to know?”
Rani replied, “People say India is on the Moon. Can you please tell us more about this?”
Aunty said, “Yes, of course. Do you know which vehicle is used to go to the Moon?”
Pratik immediately said, “I know Aunty, it is a rocket. I had seen it on the TV”.
Rani pointed to the models and photos of rockets in the room.
Nandini said, “Very good. Yes, a rocket is used to reach the Moon.”
Rani asked, “What does Chandrayaan mean?”
Nandini replied, “Chandra means Moon and Yaan means vehicle. On 14 July, 2023, India became the first country to land on the far side of the Moon.”
Rani jumped with excitement and said, “Can I go to the Moon, too?”
Nandini smiled, “Maybe, one day.”
