Chandrayaan-3 landing date & time officially announced: Check details

NEW DELHI: Chandrayaan-3 is set to land on the moon on August 23, 2023 (Wednesday), around 18:04 IST, the ISRO announced officially on Sunday. The spacecraft is now just three-day away from its final destination, the moon’s south pole.

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.

“Chandrayaan-3 is set to land on the moon on August 23, 2023, around 18:04 Hrs. IST. Thanks for the wishes and positivity! Let’s continue experiencing the journey together,” ISRO announced on X (formerly Twitter).

Live actions will be available on the ISRO website, its YouTube channel, Facebook, and public broadcaster DD National TV from 17:27 IST on Aug 23, 2023.

India's Chandrayaan-3 mission marked a giant leap in its lunar quest as the 'Vikram' lander module of the spacecraft successfully separated from the propulsion module on Thursday, and subsequently underwent crucial deboosting manoeuvres and descended to a slightly lower orbit.

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.

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 been lowered closer to the moon’s surface. It has been a month and six 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. Chandrayaan-3 components include various electronic and mechanical subsystems intended to ensure a safe and soft landing such as navigation sensors, propulsion systems, guidance, and control, among others.

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.

Chandrayaan-3 is the ISRO's follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019 and was eventually deemed to have failed its core mission objectives.

The key scientific outcomes from Chandrayaan-2 include the first-ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument, and more.

During the Chandrayaan-1 mission, the satellite made more than 3,400 orbits around the moon and the mission was concluded when the communication with the spacecraft was lost on August 29, 2009, according to the Indian Space Research Organisation (ISRO).

Meanwhile, the Chairman of the Indian Space Research Organisation (ISRO), S Somanath last week expressed confidence in the progress of the Chandrayaan 3, providing reassurance that all systems were operating as planned.

Chairman S Somanath said, "Everything is going fine now. There will be a series of manoeuvres until it lands (on the Moon) on 23rd August. The satellite is healthy."

Moon serves as a repository of the Earth’s past and a successful lunar mission by India will help enhance life on Earth while also enabling it to explore the rest of the solar system and beyond.

Historically, spacecraft missions to the Moon have primarily targeted the equatorial region due to its favourable terrain and operating conditions. However, the lunar south pole presents a vastly different and more challenging terrain compared to the equatorial region.
