The Chandrayaan program is a series of lunar missions launched by ISRO. Its main goal is to study the Moon, especially the lunar south pole, search for water ice, map the lunar surface, and develop technologies for landing and operating spacecraft on another celestial body.

What is the Chandrayaan Program?

The Chandrayaan program is India’s lunar exploration project. The word “Chandrayaan” means “Moon Vehicle” in Sanskrit.

The program focuses on:

Mapping the Moon’s surface
Studying lunar minerals
Searching for water and ice
Understanding the Moon’s atmosphere
Developing soft-landing technology
Operating robotic rovers on the Moon
Preparing for future space exploration missions

Over the years, Chandrayaan missions have helped scientists learn more about the Moon and its history.

Mission Timeline of Chandrayaan

Chandrayaan-1 (2008)

India launched its first lunar mission, Chandrayaan-1, on 22 October 2008.

The spacecraft orbited the Moon and carried scientific instruments from India and other countries.

Major Achievements of Chandrayaan-1

Achievement	Details
Discovery of Water	Confirmed the presence of water molecules on the Moon
Surface Mapping	Created detailed maps of the lunar surface
Mineral Studies	Identified various minerals present on the Moon
Scientific Data	Collected valuable information about lunar geology

Although communication with the spacecraft was lost in 2009, it successfully completed around 95% of its objectives.

The discovery of water molecules on the Moon became one of the most important findings in lunar science and brought worldwide recognition to India.

Chandrayaan-2: India’s Ambitious Moon Mission

After the success of Chandrayaan-1, ISRO planned a more advanced mission called Chandrayaan-2.

It was launched on 22 July 2019 from the Satish Dhawan Space Centre in Sriharikota using the powerful GSLV Mk III rocket.

The mission aimed to land near the Moon’s south pole, a region that had never been explored closely before.

Background of Chandrayaan-2

The project began in 2007 through a partnership between ISRO and Russia’s space agency ROSCOSMOS.

Initially:

Russia was expected to provide the lander.
India would develop the orbiter.

However, delays in the Russian lander forced changes in the project. Eventually, India decided to build the entire mission independently.

This decision marked a major milestone in India’s self-reliance in space technology.

Components of Chandrayaan-2

Chandrayaan-2 consisted of three major parts:

Component	Purpose
Orbiter	Orbit the Moon and conduct scientific observations
Vikram Lander	Soft-land on the Moon’s surface
Pragyan Rover	Move on the lunar surface and study rocks and soil

The total weight of the mission was approximately 3,877 kilograms.

Vikram Lander

The lander was named after Vikram Sarabhai, known as the father of the Indian space program.

Its objectives included:

Soft landing on the Moon
Studying the lunar atmosphere
Measuring moonquakes
Conducting scientific experiments

Pragyan Rover

Pragyan means “wisdom.”

It was a six-wheeled robotic vehicle designed to:

Move on the lunar surface
Analyze soil and rocks
Identify minerals
Measure chemical composition

The rover was powered by solar energy and designed to operate for one lunar day (about 14 Earth days).

Chandrayaan-2 Orbiter

The orbiter became the most successful part of the mission.

It continues to orbit the Moon and provide valuable scientific data.

Major Functions of the Orbiter

High-resolution imaging
Surface mapping
Mineral analysis
Water ice detection
Atmospheric studies

The orbiter carries several advanced instruments and has already produced a large amount of useful scientific information.

Scientific Instruments on the Chandrayaan-2 Orbiter

The orbiter includes advanced payloads such as:

Instrument	Function
Terrain Mapping Camera (TMC-2)	Creates detailed lunar maps
Dual Frequency Synthetic Aperture Radar (DFSAR)	Detects water ice and studies the lunar surface
Imaging Infrared Spectrometer	Studies minerals
Orbiter High Resolution Camera	Captures detailed images

These instruments help scientists understand the Moon in greater detail than ever before.

What Happened During the Landing?

The most challenging phase of Chandrayaan-2 was the landing process.

The Vikram lander successfully separated from the orbiter and began its descent toward the Moon.

However, during the final moments of landing, a software-related issue caused communication to be lost.

As a result, Vikram crashed before completing a soft landing.

Although the landing was unsuccessful, the mission was still considered an important achievement because:

The orbiter remained operational.
Valuable scientific data continued to be collected.
ISRO gained crucial experience for future missions.

Mission Objectives of Chandrayaan-2

The mission had several scientific goals.

1. Study Water on the Moon

Scientists wanted to learn:

How much water exists
Where it is located
How it is distributed

2. Explore the South Pole

The lunar south pole contains regions that remain permanently shadowed.

Scientists believe these areas may contain frozen water ice.

3. Study Lunar Surface Composition

Researchers wanted to understand:

Minerals
Rocks
Chemical elements

4. Create Detailed Maps

The mission aimed to create high-quality three-dimensional maps of the Moon.

5. Understand Lunar Evolution

Studying ancient craters and rocks helps scientists learn how the Moon formed and evolved.

Challenges Faced by Chandrayaan-2

The mission involved several technological challenges.

Launching the Heavy Rocket

The GSLV Mk III was India’s heaviest operational launch vehicle.

Launching such a massive spacecraft required precision engineering.

Long-Distance Navigation

The spacecraft traveled nearly 384,000 kilometers from Earth to the Moon.

Even a tiny navigation error could affect the mission.

Soft Landing

Landing safely on the Moon is extremely difficult because:

There is no atmosphere for parachutes.
The surface contains rocks and craters.
Temperatures are extreme.

South Pole Conditions

The Moon’s south pole receives limited sunlight.

This creates challenges for solar-powered instruments.

Chandrayaan-3: India’s Historic Success

After learning from Chandrayaan-2, ISRO launched Chandrayaan-3 in July 2023.

The mission became a historic success on 23 August 2023.

Achievements of Chandrayaan-3

Achievement	Details
Soft Landing	India became the fourth nation to achieve a soft landing on the Moon
South Pole Landing	First country to land near the lunar south pole
Rover Operations	Pragyan rover explored the surface successfully
Scientific Experiments	Conducted several important studies

This achievement made India a global leader in lunar exploration.
