Chandrayaan-3 Live updates: ISRO chief S Somnath says he's confident of a successful soft-landing on August 23, adding that agency has used learning from Chandrayaan-2 and simulations for a hitch-free touchdown.
Top ISRO scientist Nilesh M Desai said the space agency may go ahead with the August 23 landing only if conditions are favourable or a fresh attempt will be made on August 27. Several reports citing experts say the last 15-20 minutes will be crucial for the mission's success, mainly because it can't be controlled. Vikram lander will undergo a rough braking phase to change its position, which will decide the fate of the mission.

Chandrayaan-3 Live Updates: Velocity meter called doppler added to Chandrayaan 3
"About 80% changes are done (in Chandrayaan-3)... They incorporated many things into Chandrayaan-3. Earlier it was seeing only the height when it is landing, called an altimeter, now in addition to that they've also added a velocity meter called doppler, so you will know the height and also velocity, so that it can control itself," says Former ISRO Scientist YS Rajan on the safe landing of Chandrayaan-3.
Chandrayaan-3 Live Updates: Moon landing will be done from height of 30 km at velocity of 1.68 kps
The focus of the scientists would be on reducing the speed of the spacecraft above the lunar surface, said ISRO Space Applications Centre Director Nilesh Desai.
“The lander will try to land on the Moon's surface from a height of 30km on August 23, and its velocity at that time will be 1.68 km per second. Our focus will be on reducing that speed because the Moon's gravitational force will also play its part,” he added.

Chandrayaan-3 Live Updates: Chandrayaan-2 had failed in its lunar phase
Chandrayaan-2 had failed in its lunar phase when its lander 'Vikram' crashed into the surface of the Moon following anomalies in the braking system in the lander while attempting a touchdown on September 7, 2019. Chandrayaan's maiden mission was in 2008.
Chandrayaan-3 Live Updates: Did you know….
The Moon is estimated to be about 4.5 billion years old, roughly the same age as the Earth.
The leading theory about the Moon's formation suggests that a Mars-sized celestial body collided with the young Earth, and the debris from this collision eventually coalesced to form the lunar body.
However, current geological evidence from Moon suggests that it may be younger by just 60 million years compared to Earth.

Chandrayaan-3 Live Updates: Is there possibility of crash landing?
News agency ANI quoted an ISRO official, who said a “crash landing” is likely when the lander's speed is not controlled. Reduction in speed is key to Chandrayaan-3's touchdown. The lander will try to land on the Moon's surface from a height of 30 km on August 23, and its velocity at that time will be 1.68 km/sec. This speed needs to reduce, says Nilesh Desai, Director of Space Applications Centre-ISRO
Chandrayaan-3 LIVE Updates: Fingers crossed, says former ISRO chief
With thrusters, sensors, altimeters and computer software operating in unison, any glitch could jeopardise Chandrayaan 3 mission, said former ISRO chairman G Madhavan Nair said. “I understand that ISRO has done enough simulations and also redundancies have been built in so that chances of such failure are remote. Still, we have to keep our fingers crossed,” he said.

The August 23 landing takes its learnings from Chandrayaan-2, which had "partially failed" in 2019. ISRO Chief S. Somnath says "the knowledge we had on Chandrayaan-2, we have used here (in Chandrayaan-3 mission). Learning from the past experiences, the space agency has worked around the clock to deal with the complexities of the Moon's south pole which is said to have remained deprived of the sunlight for years."
