But do you know how artificial intelligence helped India create history? In this article, we look back at the undeniable contributions of artificial intelligence in the Chandrayaan-3 mission.
A Brief Overview of Chandrayaan-3
The saga commenced on July 14, 2023, when Chandrayaan-3 embarked on its cosmic journey. Anticipation rippled as it soared, with eyes set on the Moon’s mysterious south pole. On August 23, 2023, at 18:04 IST, history was etched – the triumphant touchdown of the lander and rover in the lunar south pole region.
Yet, this triumph was hard-won, with Chandrayaan-2 as a poignant precursor. Launched in July 2019, it carried an orbiter, lander, and rover. However, its lander encountered a heartbreaking deviation during descent. Undeterred, Chandrayaan-3 emerged, a symbol of resilience and determination, focused on conquering the lunar south pole.
Underneath this triumph lies AI’s unsung role. Guiding the spacecraft with precision, AI navigated complexities and ensured a secure landing. This silent force epitomized data-driven decision-making at its finest.
Collaboration also fueled Chandrayaan-3. The European Space Tracking Network (ESTRACK), operated by the European Space Agency (ESA), stood in solidarity. This partnership signifies a new age of shared expertise, amplifying space exploration’s reach.
The Synergy of AI and Spacecraft Design
At the heart of Chandrayaan-3’s triumphant lunar landing lies a sophisticated array of AI-powered sensors, a testament to modern technological marvels. These sensors encompass velocimeters, altimeters, and accelerometers that orchestrate the precision-driven landing with unparalleled accuracy. Unlike earlier lunar missions that grappled with landing deviations, Chandrayaan-3’s sensors harnessed AI’s capabilities. Armed with data from these sensors, AI models meticulously mapped the lunar topography, identified potential hazards, and recalibrated the descent trajectory to ensure a meticulously controlled landing.
Chandrayaan-3, a product of meticulous engineering, consisted of three main components, each meticulously designed to contribute to its mission:
- Propulsion Module: This module carried the lander and rover configuration into a lunar orbit of 100 kilometers. Equipped with a sizeable solar panel and a cylindrical mounting structure for the lander, this module served as the precursor to the crucial landing phase.
- Lander (Vikram): Responsible for the soft landing on the Moon’s surface, Vikram was a box-shaped marvel with four landing legs and four landing thrusters. These thrusters boasted an impressive thrust of 800 newtons each, aiding the precision landing. Unlike its predecessor, Chandrayaan-2, Vikram’s design featured four variable-thrust engines with improved attitude control and rate, maximizing its ability to navigate the descent phase.
- Rover (Pragyan): Pragyan, the six-wheeled rover with a weight of 26 kilograms, was equipped with a variety of instruments to analyze the lunar surface. With dimensions of 917 mm x 750 mm x 397 mm, this compact rover was geared to conduct in-depth research on the lunar composition, history of impacts, and more.

The AI Revolution in Lunar Descent
At the heart of Chandrayaan-3’s triumphant lunar landing lies a sophisticated array of AI-powered sensors, a testament to modern technological marvels. These sensors encompass velocimeters, altimeters, and accelerometers that orchestrate the precision-driven landing with unparalleled accuracy. Unlike earlier lunar missions that grappled with landing deviations, Chandrayaan-3’s sensors harnessed AI’s capabilities. Armed with data from these sensors, AI models meticulously mapped the lunar topography, identified potential hazards, and recalibrated the descent trajectory to ensure a meticulously controlled landing.
Chandrayaan-3’s lunar descent, considered one of the most intricate phases of space missions, was meticulously guided by AI algorithms. Here’s how AI played a transformative role:
- Orientation and Thrust Control: Unlike Chandrayaan-2, where the fifth centrally-mounted thrust engine contributed to landing failure, Chandrayaan-3’s AI-controlled descent allowed for attitude and thrust control during all descent phases. The addition of a Laser Doppler Velocimeter (LDV) enabled the precise measurement of attitude in three directions.
- Increased Attitude Correction Rate: Chandrayaan-3’s AI-driven attitude correction rate surged from 10°/s (Chandrayaan-2) to 25°/s. This upgrade facilitated swifter adjustments during descent, enhancing landing accuracy.
- Redesigned Impact Legs and Redundancy: Chandrayaan-3’s lander was equipped with stronger impact legs and improved instrumentation redundancy compared to its predecessor. These enhancements, combined with increased structural rigidity, data frequency, and transmission, bolstered the lander’s survivability during potential descent and landing failures.
- Precise Landing Region Targeting: By utilizing images from Chandrayaan-2’s orbiter’s High-Resolution Camera (OHRC), Chandrayaan-3’s AI calculated a more accurate landing region of 4 km x 4 km.
AI-Powered Scientific Payloads
Chandrayaan-3’s scientific payload, divided between the lander and rover, encompassed cutting-edge instruments that relied on AI for data analysis:
Lander Payloads:
- Chandra’s Surface Thermophysical Experiment (ChaSTE): This instrument measured the lunar surface’s thermal conductivity and temperature.
- Instrument for Lunar Seismic Activity (ILSA): Designed to measure seismic activity around the landing site.
- Langmuir Probe (LP): Estimated near-surface plasma density over time.
Rover Payloads:
- Alpha Particle X-Ray Spectrometer (APXS): Determined the chemical and mineralogical composition of lunar soil.
