LVM3-M4-Chandrayaan-3 Mission:
Presented in Collaboration with AEROGO
As the world holds its breath for the remarkable landing of Chandrayaan 3's Vikram lander on the moon's surface, the excitement is not just confined to the celestial event. This momentous occasion reminds us of the boundless possibilities of space exploration, igniting our curiosity and inspiring advancements even in the terrestrial realm of aeromodelling and aerospace engineering.
Chandrayaan-3 Live Updates: India is set to make history in less than 48 hours as its third lunar mission readies for a remarkable landing on the Moon's southern pole on August 23, 2023, around 6:04 pm (IST). On Monday, ISRO successfully established two-way communication between the Chandrayaan-3 Lander Module and the still-orbiting Chandrayaan-2 Orbiter. Earlier today, the space agency also released captivating images of the moon's far side, showcasing craters on the lunar surface, captured by Chandrayaan-3's Lander Hazard Detection and Avoidance Camera. (LHDAC). This milestone achievement positions India as the fourth nation to reach the lunar surface, following the United States, Russia, and China, while setting it apart as the sole country to conquer the lunar South Pole.
Chandrayaan 3"All’s well, we’re confident", says ISRO chief Somanath
Chandrayaan 3: ISRO is on the brink of a momentous endeavor - an upcoming mission to achieve a successful spacecraft landing on the moon's south pole. This mission holds profound significance for both India's stature as a spacefaring nation and the prospects of future lunar explorations. The launch of the Chandrayaan-3 mission took place on July 14, originating from Andhra Pradesh.
Chandrayaan 3: The Spectacular Lunar Descent of Vikram Lander
Controlled Descent Initiated: In response to commands relayed from Bengaluru, the Vikram lander embarks on its descent toward the lunar surface, commencing its journey from an altitude of 25 kilometers.
Powered Descent Velocity: Executing a powered descent, the Vikram lander hurtles at an astonishing speed of 1.68 kilometers per second towards the moon's surface—equivalent to a staggering 6048 kilometers per hour, nearly ten times the speed of an aircraft.
Transitioning Through Rough Braking: Despite its remarkable velocity, the Vikram lander begins to decelerate, engaging all engines for thrust. Maintaining an almost horizontal orientation relative to the moon's surface, this phase, referred to as the "rough braking phase," extends over approximately 11 minutes.
Shift to Delicate Fine Braking: Employing precision maneuvers, the Vikram lander gradually adjusts its position to align vertically with the lunar surface, signaling the commencement of the intricate "fine braking phase." During the Chandrayaan-2 mission, it was this phase that witnessed the Vikram lander's loss of control, leading to a crash.
Hovering Gracefully: Positioned at a height of 800 meters above the moon's surface, both horizontal and vertical velocities dwindle to zero, causing the Vikram lander to hover gracefully, conducting a survey of the landing site beneath.
Descending Further and Capturing Images: Continuing its descent, the Vikram lander draws even closer, hovering merely 150 meters above the lunar landscape. In this stage, crucial images are captured to identify potential hazards and scout for the optimal landing site.
The Grand Touchdown: The climax unfolds as the Vikram lander delicately touches down on the lunar terrain, utilizing only two engines for a controlled landing. Its robust legs are engineered to withstand an impact of up to 3 meters per second, equivalent to around 10.8 kilometers per hour.
Lander Contact Sensors Activate: Upon detecting contact with the lunar surface, the lander's leg sensors trigger the shutdown of its engines, effectively concluding the intense twenty-minute period characterized by suspense and uncertainty that defined the landing sequence.
11:41 AM - A Nation's Hope: The nation's prayers resonate as the Deputy CM of Uttar Pradesh, Keshav Prasad Maurya, expresses the firm belief that these collective prayers will materialize, leading Chandrayaan-3 to unfurl the tricolor on the moon.
11:38 AM - Celebrities' Voices: Tweets from celebrities lend their support to the mission.
11:23 AM - Preparing for Success: ISRO Chief Somanath shares confidence in the mission's progress, highlighting meticulous preparations, multiple simulations, verification, and double verification of systems. Health checks on instruments are in progress to ensure readiness.
11:21 AM - Lunar Challenges: The treacherous nature of the moon's south pole is elaborated, recounting past failed landing attempts and the complex terrain consisting of craters and deep trenches.
11:18 AM - Watch the Event Unfold: The event will be broadcasted live on ISRO's official platforms: the website, YouTube channel, and Facebook page.
11:15 AM - Post-Landing Agenda: Following the touchdown, ISRO scientists take the reins, engaging in rover operations for a lunar day. Data collected by the lander and rover's scientific instruments will be meticulously analyzed.
10:58 AM - Global Prestige and Ambitions: A successful landing propels India to join the ranks of lunar explorers, showcasing its space prowess and setting the stage for space-related investments and advancements.
10:55 AM - Unity in Achievement: Leaders across the political spectrum, like Shiv Sena's Sanjay Raut, emphasize the importance of supporting the scientific community regardless of political affiliations.
10:31 AM - A Glimpse of Past Glory: A nostalgic look back at a rendezvous with Chandrayaan 2.
10:30 AM - The Ultimate Challenge: Chandrayaan-3's most critical task is described—the intricate maneuver to slow its descent, change orientation, and execute a controlled landing on the moon's surface.
10:27 AM - Contingency Plans: If any factor indicates unfavorable conditions, the landing will be rescheduled to August 27, as communicated by the Space Applications Centre-ISRO.
10:27 AM - Reestablishing Communication: The Lander Module successfully establishes two-way communication with Chandrayaan-2's orbiter, a significant step toward mission success.
The countdown to Chandrayaan 3's historic landing continues, marking a pivotal chapter in India's journey to conquer the lunar frontier.

Exploring Chandrayaan-3: Unraveling Significance and Objectives
In a captivating pursuit of lunar exploration, Chandrayaan-3, the successor to Chandrayaan-2, embarked on its journey on July 14 from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. This mission, marked by progressive phases, culminated in the lunar lander entering the moon's orbit on August 5. With a resolute focus, Chandrayaan-3 aims to achieve a remarkable feat—landing on the uncharted south pole region of the lunar surface.
Should this endeavor be triumphant, India will etch its name as the fourth nation to achieve the monumental feat of lunar landing, joining the ranks of the United States, China, and Russia. Beyond the symbolism, Chandrayaan-3 carries the weight of ambitious goals, encompassing the study of lunar geology, mineralogy, and the potential presence of water ice on the lunar terrain. Moreover, it contributes to a deeper comprehension of the lunar environment through an array of pioneering experiments.
