India's Chandrayaan-3 will attempt to land on the moon's south pole today. Success for the moon mission will make India the fourth country to master the technology of soft landing on the lunar surface after the US, China and the erstwhile Soviet Union.
According to experts, the final 15 to 20 minutes will determine the success of the mission when Chandrayaan-3's Vikram lander with rover Pragyan will make its soft landing.
The live telecast of the event will be available on the ISRO website, its YouTube channel, Facebook, and public broadcaster DD National TV from 5:27 PM.
The Chandrayaan-3 mission was launched on July 14 from India's main space port in Andhra Pradesh.
Chandrayaan 3 Live: The "20 Minutes Of Terror" Before Moon Landing
On the day of landing, the twenty minutes of terror or T-20 kick in for a nail-biting finish.
On commands from Bengaluru, the Vikram lander will begin its descent towards the moon surface from an altitude of 25 km.
In a powered descent, the Vikram lander will start hurtling towards the moon surface at a velocity of 1.68 km per second which is nearly 6048 km per hour -which is almost ten times the velocity of an airplane.
Vikram lander will then slow down with all its engines firing - but the lander is still almost horizontal to the surface of the moon - this is called the rough braking phase which lasts for about 11 minutes.
Through some maneuvers, the Vikram lander will be made vertical to the moon surface, with this begins the 'fine braking phase'.
