Prime Minister Narendra Modi will be joining the Chandrayaan-3 landing event virtually on August 23 from South Africa.
The PM is on a three-day official visit to attend the 15th BRICS summit.
With Chandrayaan-3, ISRO will make the second attempt after 2019 to make a soft landing on the lunar surface.
The LM comprising the lander (Vikram) and the rover (Pragyan), is scheduled to make a touchdown near the south polar region of the Moon at 6:04 pm on Wednesday.
If the Chandrayaan-3 mission succeeds in making a touchdown on the moon and in landing a robotic lunar rover in ISRO's second attempt in four years, India will become the fourth country to master the technology of soft-landing on the lunar surface after the US, China and the erstwhile Soviet Union.
