India’s Chandrayaan missions are among the greatest achievements of modern space exploration. They represent the courage, intelligence, and scientific capability of ISRO (Indian Space Research Organisation). The name “Chandrayaan” means “Moon Craft”, and every mission from Chandrayaan-1 to Chandrayaan-3 has played an important role in helping the world understand the Moon.

The journey of Chandrayaan is not just a space project. It is a story of dreams, challenges, failures, success, and scientific progress. This article explains the complete story of all Chandrayaan missions, their objectives, discoveries, challenges, and impact on India and the world.

1. Introduction: India’s Dream to Reach the Moon

India’s Moon mission journey started with a vision—to explore the Moon and become a major scientific nation. Before Chandrayaan, only a few countries had attempted Moon exploration. India wanted to join this elite group.

ISRO first planned a lunar mission in the 1990s. Many thought it would be impossible because India did not have enough resources or technology. But ISRO scientists believed in themselves. After years of planning, modeling, and testing, Chandrayaan-1 became a reality.

The success of Chandrayaan-1 opened the doors for future missions. Chandrayaan-2 and Chandrayaan-3 continued the journey toward the Moon’s South Pole, a region no country had successfully landed on before.

2. Chandrayaan-1: India’s First Mission to the Moon (Launched in 2008)

2.1 Mission Overview

Launch Date: 22 October 2008
Launch Vehicle: PSLV-XL (Polar Satellite Launch Vehicle)
Mission Type: Orbiter + Impactor
Objective: To map the lunar surface and search for water

Chandrayaan-1 was India’s first-ever Moon mission, and it immediately made India the fourth country in the world to reach the Moon. The spacecraft weighed around 1,380 kg and was launched into lunar orbit successfully.

2.2 Scientific Objectives

To create a 3D map of the Moon
To study minerals on the Moon
To detect the presence of water
To study lunar atmosphere
To identify suitable landing sites for future missions

2.3 Major Instruments

Chandrayaan-1 carried 11 scientific instruments, including 5 from India and 6 from other countries (like USA and Europe).

The most famous instrument among them was:

M3 (Moon Mineralogy Mapper) by NASA

This instrument made one of the biggest discoveries in Moon science.

2.4 The Moon Impact Probe (MIP)

One of the proudest moments of Chandrayaan-1 was when ISRO released the Moon Impact Probe (MIP).
It:

separated from the orbiter
descended toward the Moon
and impacted near the South Pole

This impact helped confirm the presence of water molecules.

2.5 Biggest Discovery: Water on the Moon

The greatest achievement of Chandrayaan-1 was the discovery of water molecules (H₂O) and hydroxyl on the Moon’s surface.

Before this mission, many scientists believed the Moon was completely dry. But India’s Chandrayaan-1 changed the world’s understanding forever.

NASA later confirmed this discovery and thanked ISRO publicly.

2.6 End of the Mission

Chandrayaan-1 worked for 312 days instead of the planned 2 years.
It stopped communicating in August 2009 due to overheating.

But the mission was considered a 100% success because it achieved all its scientific goals.

3. Chandrayaan-2: India’s Second Mission — A Hard Challenge (Launched in 2019)

3.1 Mission Overview

Launch Date: 22 July 2019
Launch Vehicle: GSLV Mk III (India’s most powerful rocket)
Mission Type: Orbiter + Lander (Vikram) + Rover (Pragyan)
Objective: To soft-land near the Moon’s South Pole and study lunar soil, rocks, and environment

Chandrayaan-2 was India’s most ambitious and complex mission. For the first time, India attempted a soft landing on the Moon.

3.2 Components

Orbiter: Equipped with high-quality cameras and instruments
Lander (Vikram): Designed to land softly
Rover (Pragyan): Solar-powered rover for surface exploration

3.3 Mission Goals

Detect water ice
Study lunar surface
Analyze soil composition
Map craters and rocks
Explore the South Pole region
Test soft landing technology

3.4 What Went Right

The Orbiter was perfectly placed into lunar orbit and continues to work even today (long beyond its 1-year lifespan).
It can relay data for future missions like Chandrayaan-3.

3.5 What Went Wrong

On 7 September 2019, during the last 2.1 km of landing, Vikram lander deviated from its path due to a software and braking issue.

The lander crashed on the lunar surface.

3.6 Was Chandrayaan-2 a Failure?

Many people thought Chandrayaan-2 was a failure. But scientifically, it was a major success.
Why?

The Orbiter is fully functional and continues to send data.
India tested crucial technologies needed for landing.
India reached very close to soft-landing success.

4. Chandrayaan-3: India Creates History (Launched in 2023)

4.1 Mission Overview

Launch Date: 14 July 2023
Landing Date: 23 August 2023
Mission Type: Lander (Vikram) + Rover (Pragyan)
Launch Vehicle: LVM-3
Objective: To achieve a successful soft landing near the Moon’s South Pole

Chandrayaan-3 did not include an orbiter, as the Chandrayaan-2 orbiter was already available for communication.
This mission focused completely on landing and rover exploration.

4.2 Why Chandrayaan-3 Was Special

Before Chandrayaan-3, no country had ever soft-landed near the Moon’s South Pole.

This region is extremely rough, full of craters, and permanently shadowed areas.

4.3 Major Improvements

ISRO learned from Chandrayaan-2’s challenges and made several fixes:

Stronger legs for the lander
Better sensors
Advanced landing algorithm
Improved fuel estimation
New camera systems
Fail-safe mode for landing

4.4 Historic Achievement

On 23 August 2023, Vikram lander successfully touched down on the Moon.

India became:

The first country in the world to land near the Moon’s South Pole
The fourth country after the USA, China, and Russia to soft-land on the Moon
A global leader in low-cost space missions

This moment is one of the proudest in India’s scientific history.

5. What the Pragyan Rover Did

After landing, the Pragyan rover came out from Vikram and started exploring.

Rover Achievements

Confirmed the presence of Sulphur, Aluminum, Calcium, Iron
Detected temperature variations on the lunar surface
Analyzed lunar soil
Captured images
Explored rocks and craters

The rover worked for about 14 Earth days (one lunar day), as it was solar-powered.
