Reason Behind Chandrayaan-3 return
The precise orbit injection by the Launch Vehicle Mark-3 and optimal earth and lunar burn operations left the PM with over 100 kg of fuel, exceeding initial estimates. Capitalizing on this surplus fuel, ISRO seeks to gather additional data for upcoming lunar missions and exemplify operational strategies for future sample return missions.
Why Chandrayaan-3 Mission Started
To master the art of soft landings near the lunar south pole and conduct groundbreaking experiments using domestic instruments Vikram and Pragyaan launched. Launched on July 14, 2023, the powerful LVM3-M4 vehicle from SDSC, SHAR, Chandrayaan-3 wasn’t just a mission; it was an exploration into the dark territories of the Moon. The world already witnessed the lunar operation at the dark poles of the Moon as the rover showcases its driving prowess, leaving an indelible mark on the science and technology field.
Return Trajectory and Earth Orbits: Chandrayaan-3
Chandrayaan-3, the celestial voyager, has scripted a mesmerizing cosmic ballet with its return trajectory and strategic orbits around Earth. In a delicate operation that has been executed by ISRO, the propulsion module embarked on a journey from lunar orbit to Earth’s embrace. The celestial operation, initiated with precision on October 9, 2023, elevated the apolune altitude from 150 km to an astonishing 5,112 km, elongating the orbit period from 2.1 hours to a graceful 7.2 hours. As the lunar wanderer made four enchanting fly-bys before landing on the Moon’s sphere of influence on November 10, it embraced Earth’s orbit most finely.
While Chandrayaan-3 gently orbits Earth on November 22 at 1.54 lakh km, suddenly the propulsion module flaunts a 13-day orbital waltz adorned with a 27-degree inclination. Fear not, for the predicted minimum altitude of 1.15 lakh km assures a harmonious coexistence, steering clear of operational Earth-orbiting satellites. Amidst this cosmic ballet, the SHAPE payload orchestrates its celestial melody, capturing Earth’s beauty during special operations, including a mesmerizing operation on October 28, 2023.
ISRO’s assigned dynamics team, the best experts behind this cosmic operation, will advanced analysis tools and software modules to ensure a graceful finish for the mission Chandrayaan-3.
Operational Achievements of Chandrayaan-3
Chandrayaan-3, the extraordinary creation of ISRO, has not only left an indelible mark on the dark lunar surface but has also achieved remarkable operational milestones during its cosmic journey. Chandrayaan-3 launched on July 14, 2023, atop the LVM3-M4 vehicle from SDSC, SHAR, this lunar vehicle was specially designed on a mission to showcase its soft landing on anywhere in Moon which has been perfectly performed even on the dark lunar south pole.
The Vikram lander will remain a key experience in this space and technology field, which achieved historic news on the Moon’s surface on August 23, 2023. Deploying the Pragyan rover for scientific exploration, Chandrayaan-3 set the stage for a lunar symphony, conducting experiments and observations throughout one lunar day. The scientific instruments on both the lander and rover operated seamlessly, operating in the mysteries of the dark south lunar surface.
But the cosmic tale doesn’t end there. In an operation, the Chandrayaan-3 mission surprised astronomers with an unplanned ‘hop experiment’ on the Moon, showcasing the rover’s mobility and dexterity. This unexpected experiment of ISRO added an extra layer of success to the mission, leaving scientists and the space community in a new age.
The operational progress extended beyond lunar boundaries as the Propulsion Module (PM) was designed specially for a cosmic journey, transitioning from lunar orbit to Earth’s embrace. In a unique experiment, ISRO demonstrated not just the utility of the PM but also operational strategies for future lunar missions. The SHAPE instrument, a star performer on the Propulsion Module (PM), didn’t just stop at observing Earth. It went above and beyond, even putting on a spectacular show during a solar eclipse on October 28, 2023.
As the Propulsion Module circled Earth gracefully, ISRO’s flight dynamics team exhibited their skilful orbital operations, ensuring a controlled ending without creating any space accident. The Chandrayaan-3 mission, with its successful soft landing, on an unexpected lunar surface, and strategic return to Earth’s orbit, stands as a testament to India’s progress in mastering space and technology.
Chandrayaan-3 Mission Success Story
The Chandrayaan-3 mission stands as a resounding success, achieving its primary objectives with remarkable precision. Launched on July 14, 2023, aboard the LVM3-M4 vehicle from SDSC, SHAR, the mission aimed to demonstrate a soft landing near the lunar south pole and conduct experiments using the instruments on the Vikram lander and Pragyan rover.
The spacecraft accomplished a historic Vikram lander touchdown on August 23, 2023, deploying the Pragyan rover for continuous scientific operations throughout one lunar day. The scientific instruments on both the lander and rover operated seamlessly during this period, fulfilling the defined mission life and objectives by ISRO.
Notably, the Chandrayaan-3 mission showcased India’s advancements in space exploration, laying the groundwork for future lunar missions. The successful soft landing and operational achievements underscore the nation’s capabilities in executing complex space operations. The mission’s triumph has contributed valuable data and insights for the scientific community, furthering our understanding of the lunar environment and paving the way for future space exploration operations.
Advancements in Space Exploration India
India’s space agency is making history toward its extraordinary recent lunar exploration goals. The propulsion module, initially deployed to transport the lander-rover for the Chandrayaan-3 mission to the moon, has achieved a groundbreaking feat by returning to orbit around Earth, as revealed by the Indian Space Research Organisation (ISRO) on Tuesday.
This groundbreaking experiment, initiated with the first orbit-raising operation on October 9, has provided ISRO with invaluable insights for planning and executing a trajectory back to Earth. Despite ISRO’s successful track record of placing spacecraft in lunar orbit, this marks the first instance of bringing a module back from the moon.
The precise orbit injection by the Launch Vehicle Mark-3 (LVM3) and optimal earth/lunar burn operation resulted in an unexpected surplus of over 100 kg of fuel in the Propulsion Module (PM) after more than a month of operations in lunar orbit. Capitalizing on this opportunity, ISRO decided to utilize the available fuel in the PM to gather additional data for future lunar missions and showcase operational strategies tailored for a sample return mission.
In a unique experiment reminiscent of the landing operation with Vikram Lander, ISRO successfully moved the Chandrayaan-3’s Propulsion Module from its original orbit around the moon to a new orbit around Earth. To sustain the SHAPE payload for Earth observation, the decision was made to re-orbit the PM to a suitable Earth orbit.
The first operation, conducted on October 9, 2023, involved raising the apolune altitude from 150 km to 5112 km, significantly increasing the orbit’s period from 2.1 hours to 7.2 hours. This marks a historic moment for ISRO, showcasing its ability to adapt and innovate in pursuit of India’s lunar exploration objectives.
In Conclusion: Chandrayaan-3 Will Return Soon!
The unexpected surplus of fuel in the PM, resulting from precise orbit injections and optimal burn operations, has opened new possibilities for future lunar missions. This situation is strategically handled by ISRO to gather additional data and demonstrate mission operation strategies, especially for potential sample return missions.
The decision to bring the PM back from the moon indicates hope for ISRO’s commitment to pushing boundaries in space exploration. The ongoing operations, including Earth observations via the SHAPE device and meticulous trajectory planning, reflect ISRO’s dedication to maximizing the mission’s outcomes too.
While the exact return date of Chandrayaan-3 remains undisclosed, ISRO‘s planning and execution of operation hints at a finishing approach. The ISRO’s achievements in Chandrayaan-3 reaffirm India’s advancements in space exploration, laying the groundwork for future space missions.
As the Chandrayaan-3 mission continues to unfold, ISRO’s commitment to innovation and mission success remains great, leaving space community followers eagerly anticipating further updates on the fate of the PM and its implications for India’s lunar exploration mission.
