India is celebrating a momentous achievement as the Chandrayaan-three spacecraft touches down safely on the Moon’s surface on 23rd August 2023. This significant landing is the first by any nation at the moon’s southern pole, an accomplishment that makes this event even more remarkable.
For India, it’s a chance at redemption after the previous crash-landing of the Chandrayaan-2 lander four years ago, and the Indian Space Research Organisation (ISRO) has indicated that all systems are go and the mission is proceeding well as per schedule. Artificial intelligence and laptop knowledge will oversee the descent and touchdown.
ISRO has implemented several precautions to prevent a repeat of former missteps. The spacecraft’s legs have been fortified, software updated, and fuel capacity increased. The mission control based in Bengaluru will accumulate information from ground stations sourced from the lander.
The Chandrayaan-3 lander is designed with a failure-based approach to account for any potential problems. The spacecraft’s sensors and cameras have been extensively examined to ensure accurate positioning and navigation. Landing was scheduled for 23rd August 2023, however, if necessary, another attempt can be made on August 27. However, as of now, all systems are working as planned, and the project is expected to make a safe and soft landing.

In a phenomenal achievement for the Indian space programme, Chandrayaan-3 hovers to make history with its successful lunar landing.
If all goes according to plan, this momentous event will mark India’s triumph over past setbacks, including the unfortunate crash-landing of the Chandrayaan-2 lander four years ago.
The country is enthusiastic as the Lander Module of Chandrayaan-3 gears up for a “safe and soft landing” on the Moon’s surface this Wednesday evening.
India’s Leap to the Lunar South Pole
If the mission unfolds as intended, India will be able to establish itself as a pioneering nation by becoming the first to land a spacecraft on the lunar south pole successfully.
This feat would undoubtedly be the crowning achievement of India’s space programme, wiping away the disappointment that lingered after the Chandrayaan-2 lander’s ill-fated landing attempt in the not-so-distant past.
Precise Execution and Detailed Preparations
The Indian Space Research Organisation (ISRO) has diligently prepared for this mission. In a recent social media update, ISRO mentioned that the Mission Operations Complex (MOX) has been bustling with energy and excitement as the final stages approach.
The meticulous planning and execution are reflected in the confidence displayed by ISRO, with them affirming that the mission is proceeding as scheduled and smooth sailing continues.
A Delicate Descent
The anticipated touchdown of the Chandrayaan-3 lander is scheduled for 1804 hours IST on Wednesday, following a 17-minute descent from its current pre-landing lunar orbit.
The Telemetry Tracking and Command Centre (ISTRAC) in Bengaluru will play a crucial role by issuing a command at 1747 hours, signalling the spacecraft to initiate its descent.
With a velocity of approximately 6,000 km/hour, the spacecraft must decelerate to nearly zero as it touches down. Remarkably, the design ensures a safe landing even at speeds as low as 10 km/hour.
Autonomy and Vigilance
The descent phase is a testament to autonomous operation driven by artificial intelligence and computer logic. ISRO’s mission control at ISTRAC will maintain close vigilance throughout this critical phase.
The final approach, however, will be a mix of anxiety, nervousness, and anticipation, as history has shown that the last moments before landing can be the most challenging.
Recent missions, including Russia’s Luna-25, have encountered similar challenges, emphasizing the complexity of such endeavours.
Fortified Safeguards
ISRO is resolute in preventing a repeat of past mishaps. Multiple layers of safeguards have been integrated into Chandrayaan-3’s design.
The emphasis on these measures reflects ISRO’s commitment to overcoming obstacles. At the time of this update, the journey has been characterized by “smooth sailing,” a testament to the meticulousness of the preparations.
Communication and Contact

Mission control will receive critical data directly from the Chandrayaan-3 lander through ground stations at the Deep Space Network in Bengaluru, the Jet Propulsion Laboratory in the US, and a European Space Agency station in Spain.
Additionally, communication through the Chandrayaan-2 orbiter, established on Monday, enhances the data flow.
AI-Powered Landing
As the descent phase initiates, mission control relinquishes command. The lander is designed to rely on its programmed AI to ensure a “safe and soft landing.”
ISRO chairman S Somanath underscores that Chandrayaan-3’s design follows a failure-based approach, meticulously accounting for various failure scenarios and incorporating corresponding safeguards.
Addressing Past Lessons
Learning from the Chandrayaan-2 failure, ISRO has rectified software anomalies that contributed to the previous setback. Chandrayaan-3’s core lies in its sensors, which are pivotal for remote operations.
Sensors such as velocimeters, altimeters, hazard-avoidance cameras, and inertia-based cameras collectively provide crucial data for accurate navigation and orientation. Rigorous testing has validated the reliability of these sensors.
Aim for Daylight
The Chandrayaan-3 lander is strategically aiming for a landing at the commencement of the Moon’s daytime, lasting 14 Earth days.
This timing is essential to maximize the operational window of the solar-powered instruments onboard. Designed to function optimally for a lunar day, equivalent to 14 Earth days, these instruments will gather valuable data during this period.
Unyielding Dedication
As the final moments approach, the senior ISRO official confirms that an alternative landing attempt could be made on August 27 if circumstances require.
However, the preference is for an immediate landing to align with the start of the Moon’s daytime. The meticulous planning underscores ISRO’s commitment to making this mission a success.
An Ingenious Design
Somanath’s insight reveals that Chandrayaan-3’s design prioritizes safety and redundancy. Even in the face of sensor failures or other challenges, the propulsion system’s integrity is crucial.
The design’s resilience ensures that a successful landing remains within reach even if some engines malfunction. The lander’s architecture is engineered to tackle multiple failure scenarios.
The Unveiling of a New Chapter
As the world watches, India’s Chandrayaan-3 mission represents a remarkable step forward in lunar exploration. The culmination of meticulous planning, technological prowess, and lessons learned from past experiences underscores India’s commitment to pushing boundaries.
With every precaution taken and every challenge addressed, the stage is set for a moment of historic significance—the successful landing of Chandrayaan-3.
