New Delhi: Chandrayaan-3's Vikram lander underwent a crucial deboosting manoeuvre and descended to a slightly lower orbit on Friday, after successfully getting separated from the propulsion module the day before. The deboosting manoeuvre was scheduled at around 1600 IST.
"The Lander Module (LM) health is normal. LM successfully underwent a deboosting operation that reduced its orbit to 113 km x 157 km. The second deboosting operation is scheduled for August 20, 2023, around 0200 Hrs. IST," tweeted ISRO.

Deboosting is the process of slowing down to position itself in an orbit where the orbit's closest point to the Moon (Perilune) is 30 km and the farthest point (the Apolune) is 100 km. “LM (lander module) is set to descend to a slightly lower orbit upon a deboosting planned for tomorrow around 1600 Hrs., IST,” ISRO posted on X (formerly Twitter) on Thursday while announcing the successful separation of the lander from the propulsion module.
The Chandrayaan-3 mission's lander is named after Vikram Sarabhai (1919–1971), who is widely regarded as the father of the Indian space programme. On Wednesday, the spacecraft carried out the final lunar-bound orbit reduction manoeuvre of the Chandrayaan-3 spacecraft, a week ahead of its scheduled landing on the south pole of the moon on August 23. A GSLV Mark 3 (LVM 3) heavy-lift launch vehicle was used for the launch of the spacecraft that was placed in the lunar orbit on August 5 and since then it has been through a series of orbital manoeuvres.
It has been a month and three days since the Indian Space Research Organisation launched the Chandrayaan-3 mission on July 14. The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota. ISRO is bidding to make a successful soft landing on the moon, which will make India the fourth country in the world to achieve the feat after the United States, Russia, and China. The stated objectives of Chandrayaan-3, India's third lunar mission, are safe and soft landing, rover roving on the moon's surface, and in-situ scientific experiments. The approved cost of Chandrayaan-3 is Rs 250 crores (excluding launch vehicle cost). Chandrayaan-3’s development phase commenced in January 2020 with the launch planned sometime in 2021. However, the COVID-19 pandemic brought an unforeseen delay to the mission's progress. (ANI)
