CHANDRAYAAN 3 : A JOURNEY
TO THE UNKNOWN

2. Introduction
National Space Day in India, officially
declared on August 23, celebrates the
nation's growing prowess in space
exploration. This day commemorates the
tremendous success of India's moon
mission (Chandrayaan 3), marking a
significant milestone in the country's
journey towards becoming a global
leader in space science.

3. Previous Missions
Chandrayaan-1, launched in 2008, was India's first lunar
mission. It successfully orbited the Moon and made a
groundbreaking discovery by confirming the presence of water
molecules on the lunar surface. This mission marked India's
entry into deep space exploration and showcased its growing
capabilities in space science.
Chandrayaan-2 is India's second lunar exploration mission,
launched in 2019 by ISRO. The mission aimed to explore the
Moon's south pole, consisting of an orbiter, lander (Vikram),
and rover (Pragyan). While the lander faced a setback during its
descent, the orbiter continues to provide valuable data on the
Moon's surface, furthering India's space exploration
capabilities.

4. Lunar Triumph
Chandrayaan 3 is India's latest lunar mission,
launched by ISRO to achieve a successful soft
landing on the Moon. Building on the lessons
from Chandrayaan 2, this mission focuses on
deploying a lander and rover to explore the lunar
surface, further advancing India's ambitions in
space exploration and solidifying its position as a
key player in global lunar research.

5. Mission Cycle
Launching of Chandrayaan-3 took place aboard the LVM3-M4
rocket on 14 July 2023 at 09:05 UTC from the Second Launch
Pad at Satish Dhawan Space Centre in Srihari Kota, Andhra
Pradesh, India. The mission successfully entered an Earth
parking orbit with a perigee of 170 km (106 mi) and an
apogee of 36,500 km (22,680 mi).
Landing of Chandrayaan-3, occurred on August 23, 2023,
approximately 600 kilometers from the Moon's South Pole.
The Vikram lander achieved a historic soft landing in this
region, marking the first of its kind for humanity and making
India the fourth country to land on the Moon. Following the
landing, the Pragyan rover descended the ramp and traveled
8 meters (26 ft), making India the third nation to operate a
robotic rover on the lunar surface.

6. Objectives
•To demonstrate safe and soft landing on lunar surface.
•Strengthen India's technological prowess in space missions.
•It is aimed to conduct scientific study about the Atmosphere, Environment and
Geology of the southern region of the moon

7. Modules
Lander (Vikram) Designed to achieve a soft landing on the Moon's
surface, equipped with scientific instruments to conduct experiments
and relay data.
Rover (Pragyan) is A small, mobile vehicle deployed by the lander to
explore the lunar surface, perform in-situ analysis, and send back
valuable scientific data.
Propulsion Module is Responsible for carrying the lander and rover
from Earth to lunar orbit, also equipped with scientific payloads to
study the Earth-Moon system.

12. The Chandrayaan 3 lander is set to attempt a lunar touchdown at a near-polar
location of 69.37°S, 32.35°E, approximately 100 kilometers east of the
Chandrayaan 2 landing site (70.83°S, 22.67°E) within the same larger rocky
highland region. This location is called Shiv Shakti Point.
Similar to other lunar highlands, the Chandrayaan 3 landing area is expected
to contain ancient lunar crust material, along with debris from nearby craters
formed during the heavy bombardment by asteroids and comets around 3.8
to 4.1 billion years ago. These materials are prime targets for analysis by the
two spectrometers onboard Chandrayaan 3’s rover.

13. Key Information
•The weight of Chandrayaan-3 about 3900kg.
•Mission life of Propulsion module is 3-6 months.
•The life of Rover is 1 Lunar day (15 earth days).
•The Budget of the mission is approximately Rs. 600 cr.
•It took 41 days to reach Lunar surface.
•Total distance travel by Chandrayaan-3 is approx. 3lacs km.
•Vikram will gather thermal conductivity data and detect moonquakes.
•Pragyan will perform experiments and deliver crucial insights into the Moon’s composition.
