Today, let’s travel on this lunar adventure, clear your exam worries, and answer all your curious questions in a fun, friendly way. Ready for lift-off? Let’s begin!
What’s So Special about Vikram Lander?
Meet India’s Own Moon Lander
Vikram Lander is a hi-tech robot spaceship built by ISRO, the Indian Space Research Organisation. It is named after Dr. Vikram Sarabhai, who is known as the “father of the Indian space program.” Vikram’s main mission? To land softly on the Moon, especially near the rocky south pole, and help Indian scientists study the lunar surface. It was a big part of Chandrayaan-2 in 2019 and the super-famous Chandrayaan-3 in 2023!
Why Does Everyone Talk about Vikram Lander?
- Vikram Lander showed that Indian technology can land gently on the Moon—something only a few countries have done!
- It carried the Pragyan Rover, another Indian space robot, to do fun science tricks on the lunar surface.
- It became a hot topic for CBSE, UPSC, and other exam questions all over India.
How Did India Build and Launch Vikram Lander?
A Fun Timeline: From Dream to Moon Touchdown
- 2018: ISRO finished building the first Vikram Lander for Chandrayaan-2.
- 22 July 2019: Chandrayaan-2 soared sky-high from Sriharikota with Vikram on board.
- 6 September 2019: Vikram tried to land, but lost contact just before the finish line—it crash-landed, but taught ISRO many lessons.
- 2019–2022: Indian scientists worked super hard to make Vikram better, stronger, and smarter for round two.
- 14 July 2023: Chandrayaan-3 lifted off carrying the upgraded Vikram Lander.
- 23 August 2023: Hooray! Vikram Lander made India proud by landing softly near the Moon’s south pole—the first-ever by any country!
- After Landing: Pragyan Rover rolled out for Moon walks and did experiments for about 14 Earth days.
Why the South Pole?
The lunar south pole is extra special! Scientists believe it has water ice under the surface and untouched rocks from the Moon’s earliest days. Studying this place could help astronauts live on the Moon in the future—and Vikram helped start that journey!
How Does Vikram Lander Work? Let’s Peek Inside!
Technology in Simple Words
- Weight: About as heavy as a small car—1,752 kg on Chandrayaan-3!
- Solar Power: It spreads shiny solar panels like arms to catch sunlight and make electricity.
- Super Eyes: Strong cameras and sensors help Vikram “see” where to land safely.
- Brakes and Thrusters: Powerful rocket engines slow it down for a gentle Moon touchdown.
- Smart Brain: A built-in computer checks everything before and during landing.
- Science Tools: Carries experiments to find out about lunar soil, quakes, and more.
Vikram’s Best Friend: What’s Pragyan Rover?
Pragyan is a tiny robot car (just 27 kg!) that rolled out from Vikram. Its name means “Wisdom” and it studies rocks and leaves fun tire marks on the Moon. But remember: Vikram Lander is the landing station; Pragyan is the explorer.
