Chennai,19 August(City Times): Chandrayaan-3’s Vikram lander module, a crucial component of India’s Moon mission, achieved a significant milestone on Friday. As Vikram Lander Nears Moon It executed a successful deboosting manoeuvre, a critical step in its journey. The mission, which embarked on its journey from Earth on July 14, is now edging closer to a highly anticipated soft landing attempt, provisionally scheduled for August 23.
Countdown to Lunar Touchdown:
Chandrayaan-3 is on track to touch down on the lunar surface around August 23. The spacecraft has undergone a 40-day journey to reach this point, marking a crucial phase in India’s space exploration endeavors. This mission carries the hopes and expectations of scientists, engineers, and space enthusiasts, eager to see its successful completion.
Preparation for Lunar Descent:
Ahead of the soft landing attempt, a second deboosting operation is scheduled for August 20. This maneuver aims to gradually lower the lander module into lunar orbit, a pivotal step that will pave the way for the forthcoming soft landing. A successful execution of this operation would set the stage for the Vikram Lander and Pragyan rover to commence their mission, anticipated to last for one lunar day, equivalent to approximately 14 Earth days.
Chandrayaan-3’s Lunar Target:
The Moon’s south pole, with its challenging topography, has emerged as a prized objective. Scientists hold great interest in this region due to the potential presence of substantial ice deposits. These ice reserves could hold vital resources such as fuel, oxygen, and even drinkable water, making the south pole a strategically valuable destination for exploration.
Race to the Lunar Surface:
The question of which lander—Chandrayaan-3 or Russia’s Luna 25—will make first contact with the lunar surface has captivated global attention. Russia’s Luna 25 spacecraft, launched on August 11, is poised to take roughly five days to reach the Moon. Following this, it will spend an additional five to seven days in lunar orbit before descending to its designated landing site near the pole. This timeline positions Russia’s mission for a possible concurrent or slightly earlier arrival compared to India’s Chandrayaan-3.
Coexistence in Lunar Realm:
Assuaging concerns of potential clashes, Russia’s space agency Roscosmos has emphasized that both missions are meticulously planned with distinct landing areas. The agency stated that there is ample space for both missions on the Moon’s surface, minimizing the risk of interference or collision. This reassurance from Roscosmos underscores the international cooperation and prudent planning guiding these landmark space endeavors.
The Gravity “Trick”:
The soft landing challenge facing Chandrayaan-3 is highlighted by ISRO Chairperson S Somanath. He emphasized the complexity of transitioning the spacecraft from a horizontal orientation, at an initial velocity of 1.68 km per second, to a vertical orientation suitable for landing. This maneuver requires precision and expertise, underscoring the technical prowess of India’s space agency.
Global Lunar Presence:
Amidst these developments, a diverse array of lunar orbiters continues to operate around the Moon. ISRO’s Chandrayaan-2 and Korea Pathfinder Lunar Orbiter (KPLO), along with NASA’s Lunar Reconnaissance Orbiter (LRO) and Artemis initiative’s Artemis P1 and Artemis P2, contribute to a growing understanding of the lunar environment. This collaborative international effort underscores humanity’s shared interest in unraveling the Moon’s mysteries.
As the world watches in eager anticipation, both Chandrayaan-3 and Luna 25 are poised for their respective lunar landings. The competition highlights the spirit of exploration, technological innovation, and international cooperation driving humanity’s quest to explore the uncharted territories of the Moon’s south pole.
Navigating Lunar Challenges:
The impending soft landing of Chandrayaan-3 is not without its challenges. ISRO’s Chairperson, S Somanath, has pointed out a critical hurdle—tilting the spacecraft from a horizontal position to a vertical one. Beginning with an initial velocity of 1.68 km per second, the craft must execute a precise “tilt” to align itself vertically for landing. This technical maneuver demands a delicate balance of speed, orientation, and control, underscoring the complexity of lunar missions.
Lunar Orbiters in Action:
Amid the anticipation of upcoming landings, the lunar vicinity remains bustling with activity. The National Aeronautics and Space Administration’s (NASA) Lunar Reconnaissance Orbiter (LRO) maintains a carefully orchestrated path, tracing a nearly polar and slightly elliptical trajectory around the Moon. ISRO’s Chandrayaan-2 and Korea Pathfinder Lunar Orbiter (KPLO) contribute to the global effort, navigating polar orbits at an altitude of 100 km. Meanwhile, NASA’s Capstone and the repurposed THEMIS probes (now Artemis P1 and P2) continue their eccentric orbits, gathering valuable data from various vantage points.
A Lesson-Fueled Future:
Chandrayaan-3 follows in the footsteps of its predecessor, Chandrayaan-2, which encountered a setback in September 2019. During its landing attempt, the Vikram lander veered off course, leading to communication loss. These lessons, painful yet instructive, have been woven into Chandrayaan-3’s fabric. The mission integrates refined algorithms, software enhancements, and strategic adjustments to bolster its chances of success. As the world holds its breath, the culmination of these collective efforts and newfound insights will determine the mission’s triumph.
As the countdown continues, the world awaits the outcome of Chandrayaan-3’s daring endeavor, which could pave the way for innovative resource extraction, scientific exploration, and further collaboration on the Moon. With the Moon’s south pole as the backdrop, India’s ambitious mission and Russia’s Luna 25 herald a new era of lunar exploration, fueled by a blend of pioneering spirit, technological innovation, and international partnership.
