The Chandrayaan 3 rover is a marvel of science. It was built by smart engineers in India. The rover was carried by a big rocket. This rocket is the LVM3. It took off from Sriharikota. The journey took about 40 days. The landing was the hardest part.
Once the lander Vikram touched down, the real work began. A ramp opened up. Pragyan slid down gently. It touched the lunar surface. This was a proud moment. The rover is not very fast. It moves at 1 centimeter per second. It uses the sun for energy.
It has a vertical solar panel. This panel catches sunlight. The rover communicates with the lander. The lander sends data to Earth. Pragyan had a lifespan of one lunar day. This is equal to 14 days on Earth. It had to finish all work quickly.
It did many experiments. It used a laser to zap rocks. The gas from the rock told scientists what was inside. It confirmed many minerals. It faced a big crater once. It had to change its path. It was a brave little explorer. It fulfilled all its promises.

Chandrayaan 3 is a symbol of India’s power in space. The mission had three parts. A propulsion module, a lander, and a rover. The rover, Pragyan, was the star. It was kept safe inside the lander. The landing spot is called Shiv Shakti Point. It is near the South Pole.
No other country has landed there. The terrain is rugged and dangerous. But Pragyan was ready. It has six wheels with a rocker-bogie system. This helps it climb over small rocks. It does not fall over. The rover has two eyes. These are navigation cameras.
They help it see the path. Scientists at ISRO controlled it. They told it where to go. But there is a time delay. So, the rover is also smart. It can sense danger on its own. Its main job was to study the soil.
It carried two main payloads. One is the APXS. The other is the LIBS. These are fancy names for testing tools. They sniffed the dirt for elements. Finding Sulphur was a big surprise. It suggests volcanoes might have existed.
On September 2, the mission ended. The sun was setting on the Moon. Without sun, the rover has no power. It was put into sleep mode. Its battery was fully charged. The solar panel was set to face the next sunrise. We hope it wakes up. But even if not, it did a great job.

The story of Chandrayaan 3 is inspiring. It shows that failure is a step to success. Chandrayaan 2 had crashed. But ISRO did not give up. They built a better machine. The rover Pragyan is the result of this hard work. It is a small square robot.
It looks like a toy but works like a genius. It weighs only 26 kg. It is gold in color. The mission launched on July 14, 2023. The whole world watched. On August 23, it landed. India became the fourth nation to land on the Moon.
But it was the first to the South Pole. This area is important. Scientists think there is water ice there. Water is key for future human bases. Pragyan did not find water ice directly. But it found Oxygen.
This is a good sign. The rover moved around the lander. It covered a distance of over 100 meters. This is a long walk for a small robot. It sent back beautiful photos. We saw the lander standing tall. We saw the long shadows of the moon.
The rover faced extreme heat and cold. The days are hot. The nights are freezing. Electronics can die in the cold. That is why it sleeps at night. The rover has left a legacy. Its tracks are on the moon dust.
This dust does not move much. So, the tracks will stay for millions of years. Future humans might see them. They will know that India was there. Pragyan taught us about the moon’s history. It helps us plan trips to Mars. It is a tiny hero in a vast universe.

Introduction
Space is the final frontier. Humans are curious to explore it. The Moon is our closest neighbor. India sent a special mission there. It is called Chandrayaan 3. The most exciting part was the rover. Its name is Pragyan. It is a wheeled robot. It acts like a scientist on the Moon. It goes where humans cannot go. It works in harsh conditions. Its success has put India on the top list of space nations.
The Mission Journey
The journey started at the Satish Dhawan Space Centre. A huge rocket named LVM3 lifted off. It carried the spacecraft. It circled the Earth many times. Then it flew towards the Moon. It entered the Moon’s orbit. The lander, Vikram, separated. It slowly lowered itself. It scanned for a safe spot. On a Wednesday evening, it touched down. The dust settled. Then, the rover Pragyan came out. It rolled down a foldable ramp. It was a magical moment.
Design of Pragyan
Pragyan is built to last. It is rectangular. It has six wheels. These wheels have independent drive. This means they can move alone. This helps on rough ground. The wheels leave a mark. One side has the Ashoka Pillar. The other has the ISRO logo. The rover has cameras in the front. They act like eyes. It has an antenna to talk. It talks to the lander. The lander talks to Earth. The rover cannot talk to Earth directly.
Scientific Discoveries
The main goal was science. Pragyan carried two payloads.
1. LIBS: Laser Induced Breakdown Spectroscope. It shoots a laser at rocks. The rock turns to plasma light. The sensor reads this light. It tells what the rock is made of.
2. APXS: Alpha Particle X-ray Spectrometer. It shoots particles at the soil. It reads the energy that comes back.
These tools found many elements. They found Iron, Titanium, and Aluminum. They also found Sulphur. This was the first time Sulphur was found on the South Pole.
Challenges Faced
Operating a rover is hard. The moon has low gravity. It is 1/6th of Earth. The rover could bounce or tip over. The dust is also a problem. Moon dust is sharp. It can stick to sensors. It can jam wheels. The team had to be careful. Also, the time was short. They had only 14 days of sunlight. After that, the night lasts 14 days. The temperature drops to -200 degrees Celsius. The rover freezes.
Conclusion
Pragyan finished its tasks. It was put to sleep on September 2. It faces the east to catch the next sunrise. We do not know if it will wake up. But its job is done. It gave us data for years of study. It inspired millions of children. It showed that the sky is not the limit.

Introduction
Exploration is in human nature. We always want to know what is out there. The Moon has always called us. In 2023, India answered that call again. The mission was Chandrayaan 3. It was a follow-up to Chandrayaan 2. The previous mission had a crash landing. But failure teaches us lessons. ISRO learned and improved. This time, they succeeded. The mission had a lander named Vikram and a rover named Pragyan. The rover was the mobile explorer. It was the eyes and hands of India on the lunar surface. This essay explores the journey, design, and impact of the Chandrayaan 3 rover.
The Background
Chandrayaan means “Moon Vehicle” in Hindi. The first mission found water molecules. The second mission tried to land. It failed at the last minute. Chandrayaan 3 was planned to fix this. The focus was on a safe landing. Without a safe landing, the rover cannot work. ISRO made the legs of the lander stronger. They added more fuel. They improved the software. They wanted to ensure the rover could come out safely.
Launch and Landing
The mission launched on July 14, 2023. It used the LVM3-M4 rocket. This is India’s heaviest rocket. It is often called “Fat Boy” because of its power. The spacecraft went into space perfectly. It took a long path to save fuel. It used Earth’s gravity to swing. Then it used the Moon’s gravity.
On August 23, the world held its breath. The lander began its descent. It was the “20 minutes of terror.” Computers controlled everything. The engines fired to slow it down. It hovered above the surface. It looked for a flat spot. Then, it landed gently. India became the first nation to reach the lunar South Pole region. It was a moment of national pride.
Enter Pragyan: The Rover
Pragyan was stored inside the belly of Vikram. After the dust settled, a ramp unfolded. A wire cut the lock. The rover rolled out. Its speed was very slow. It moved at 1 cm per second. This is slower than a snail. But speed was not needed. Safety was needed.
Pragyan is a six-wheeled rover. It weighs 26 kg. It runs on 50 watts of power. It has a solar panel on one side. This panel must face the sun. The wheels have a “rocker-bogie” mechanism. This design is used for rough roads. It helps the rover climb over obstacles up to 50 mm high.
The Scientific Tools
Pragyan is a lab on wheels. It carried two major instruments.
1. LIBS (Laser Induced Breakdown Spectroscope): This is a very cool tool. It is mounted on the front. It fires high-energy laser pulses. It hits the soil or rock. The material gets very hot and melts into plasma. The light from this plasma is analyzed. Each element gives a different light color. This tells us the composition.
2. APXS (Alpha Particle X-ray Spectrometer): This tool is on the back. It is lowered close to the ground. It emits alpha particles and X-rays. It detects elements like Magnesium, Aluminum, Silicon, Potassium, Calcium, Titanium, and Iron.
These tools worked perfectly. They sent data packets to the lander. The lander sent them to the Indian Deep Space Network. The biggest find was Sulphur. This confirms that the moon had volcanic activity in the past.
The Moon Walk
Pragyan had a short life planned. It was designed for one lunar day. This is 14 Earth days. During this time, the sun shines on the landing spot. The rover wakes up with the sun. It works all day. It sleeps when the sun sets.
The ISRO team in Bangalore drove the rover. They saw obstacles on the camera. They planned the path. One day, the rover saw a big crater. It was 4 meters wide. If the rover fell in, it would be stuck. The team stopped it in time. They turned it around. It was a close call.
Pragyan also did a fun spin. It rotated in place. It looked like a child playing. It took a photo of the lander Vikram. This photo is iconic. It shows the lander standing on the grey soil.
The Symbolic Marks
The rover had a special feature on its wheels. The rear wheels had 3D embossings. One wheel had the Lion Capital of Ashoka. This is India’s national emblem. The other wheel had the ISRO logo. As the rover moved, it pressed these marks into the dust.
On Earth, wind and rain wash away footprints. But the Moon has no air. There is no wind. So, these marks will not fade. They will stay there for a very long time. They mark India’s presence on the Moon.
The End of the Mission
By September 2, the lunar day was ending. The sun was going down. The solar panels would stop working. The temperature would drop very low. Electronics cannot survive -200 degrees without heat.
ISRO commanded the rover to park. They parked it in a safe spot. The receiver was kept on. The battery was full. They hoped it might survive the cold night. The night lasts 14 Earth days. On September 22, the sun rose again. ISRO tried to wake it up. But there was no signal. Pragyan remains a silent ambassador on the Moon.
Conclusion
Chandrayaan 3 is a huge success. The total cost was low compared to other countries. It showed that India has top technology. The rover Pragyan gathered gold-standard data. This data helps scientists all over the world.
It inspires young students. Many now want to become scientists. They look at the moon and know their country is there. Pragyan was small, but its impact is giant. It proved that with wisdom and hard work, we can reach the stars.
