Chandrayaan 3: A New Lunar Leap—ISRO’s Mid-July Robotic Moon Landing Mission

The race to explore the cosmos continues as nations invest in scientific advancements and ambitious projects. The Indian Space Research Organization (ISRO) has played an important role in both India’s space efforts and the international space community fields since its foundation in the year 1969. Because of the Chandrayaan missions, ISRO has achieved great progress and has been at the forefront of the growing interest in the subject of lunar exploration.

As we are gradually getting closer to the mid-July, i.e. launch of ISRO’s newest moon mission, Chandrayaan 3, it’s time to get back to India’s history of lunar exploration. And understand the significance of successful lunar missions that play an important role in influencing the future of space exploration, and delve into the excitement surrounding this ground-breaking endeavour.

Chandrayaan 3: A Fresh Attempt

As ISRO gets ready for the launch of Chandrayaan 3, its most recent moon mission, a new chapter in lunar exploration is about to begin. With a specific emphasis on completing a gentle landing on the lunar surface and carrying out scientific investigations through its rover, this ambitious project hopes to build upon the achievements and lessons learned from the earlier Chandrayaan missions.

Overview of the Mission

Chandrayaan 3 is India’s third lunar mission, following the orbiter mission Chandrayaan 1 and the partially successful lunar mission Chandrayaan 2. The primary objectives of Chandrayaan 3 include demonstrating a soft landing on the moon’s surface and conducting in-depth scientific analysis through its rover. 

Key Components of the Spacecraft

1. Lander: The lander is a crucial element of the Chandrayaan-3 mission, designed to safely touch down on the lunar surface. Equipped with advanced propulsion and control systems, the lander will use a combination of braking and precision manoeuvres to ensure a controlled descent onto the Moon’s terrain.
2. Rover: The rover is a six-wheeled, solar-powered vehicle that will traverse the lunar surface, conducting experiments and collecting data. With state-of-the-art instruments, the rover will analyze lunar soil samples, study the moon’s surface composition, and search for signs of water ice, among other objectives.

Differences and Improvements from Chandrayaan-2

While Chandrayaan-2 successfully placed its orbiter around the moon, the lander, Vikram, encountered complications during its descent, ultimately resulting in a hard landing. Learning from this experience, ISRO has made several improvements to the Chandrayaan 3 mission:

1. Enhanced Lander Design: The lander for Chandrayaan 3 has been redesigned with upgraded systems to improve its performance during the descent and landing stages.
2. Refined Navigation and Control Systems: ISRO has made significant advancements in the navigation and control systems for the lander, ensuring a more accurate and controlled descent.
3. Optimized Mission Planning: The mission timeline and trajectory have been optimized to maximize the chances of success and to conduct scientific experiments on the lunar surface efficiently.

Countdown to the Mid-July Launch

As the countdown begins for Chandrayaan 3’s mid-July launch, excitement builds around this highly anticipated moon mission. From rigorous preparations and testing to understanding the capabilities of the launch vehicle, let’s explore the crucial steps leading up to the launch and the expected timeline of events that will unfold once the spacecraft takes flight.

4. Launch vehicle and its capabilities

Chandrayaan 3 will be launched aboard ISRO’s trusted workhorse, the Geosynchronous Satellite Launch Vehicle (GSLV). The GSLV boasts an impressive track record and offers several key capabilities:

1. Payload capacity: The GSLV is capable of carrying a payload of up to 4 tons into geostationary orbit, providing ample capacity for the Chandrayaan 3 spacecraft.
2. Proven reliability: With numerous successful launches under its belt, the GSLV has demonstrated its reliability and performance, making it an ideal choice for the critical Chandrayaan 3 mission.
3. Versatility: The GSLV can accommodate various types of payloads and spacecraft, making it a versatile and adaptable choice for a range of missions, including lunar exploration.
4. Expected Timeline of Events After the Launch

Following the mid-July launch, Chandrayaan 3 will embark on a series of events as it makes its way to the Moon:

1. Translunar injection: The spacecraft will separate from the launch vehicle and perform a series of orbital manoeuvres to leave Earth’s orbit and begin its journey toward the Moon.
2. Lunar orbit insertion: Upon reaching the Moon’s vicinity, Chandrayaan-3 will conduct a lunar orbit insertion manoeuvre to be captured by the Moon’s gravity and enter a stable orbit.
3. Lander descent: Once in lunar orbit, the lander will separate from the orbiter and begin its controlled descent to the lunar surface, aiming for a soft landing at the selected site.
4. Rover deployment: After a successful landing, the rover will be deployed from the lander to explore the lunar surface and conduct experiments.

As the world eagerly awaits the mid-July launch of Chandrayaan-3, the mission promises to advance our understanding of the moon and showcase the capabilities of India’s thriving space program.
