“Chandrayaan-3 to make history…”: Former ISRO scientist ahead of soft landing

New Delhi [India], August 23 : With only hours left for the much-anticipated Chandrayaan-3 mission, former ISRO scientist Mylswamy Annadurai on Wednesday said that by being the first to make a soft landing on the lunar polar region, the mission is set to make history. 
While talking to ANI about the mission, Annadurai said, "So far so good and we expect as per plan 'A' today we must be able to land. Like anyone else, I am also eagerly waiting.”
He said that after the discovery of water by Chandrayaan-1 the world was trying to look at the moon differently.
“Our Chandrayaan-1 was the first. Similarly, Chandrayaan-3 is going to make history by being the first to land softly on the lunar polar region. And now various nations including USA, Russia, China, Japan, European countries are very, very ambitiously trying to do bigger missions,” he added.
Further talking about the soft landing, the former ISRO scientist said, “Actually in effect, our presence is already there in the south pole with the tricolour flag along with the Moon Impact Probe. Chandrayaan-1 itself made our presence. But that time it was an impacted probe as planned."
"But now I think we are going to land softly and that will enable logical extension about what to do in the place. Everything calls for a soft landing. The soft landing will help us, and enable us to be in the lead as far as the Moon campaigns are concerned. So that way I think India can keep its edge technical,” he said. 
Meanwhile, the Indian Space Research Organization (ISRO) has announced that it is all set to initiate the Automatic Landing Sequence (ALS).
"All set to initiate the Automatic Landing Sequence (ALS). Awaiting the arrival of the Lander Module (LM) at the designated point, around 17:44 Hrs. IST. Upon receiving the ALS command, the LM activates the throttleable engines for powered descent," ISRO said in a post on X, formerly Twitter. 
"The mission operations team will keep confirming the sequential execution of commands. The live telecast of operations at MOX begins at 17:20 Hrs. IST," read the post further. 
The attempted soft landing of Chandrayaan-3 on the moon’s south pole has been scheduled for around 18:04 IST, with the powered descent of the Vikram lander expected at 1745 IST.
The live telecast of the landing operations at Mission Operation Complex (MOX) will begin at 1720 IST. Live broadcast of the landing 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.
In an earlier update on the soft landing by the Chandrayaan-3 lander, ISRO had said the mission is on schedule and systems are undergoing regular checks. It also released a series of up-close images of the moon. The images will assist the lander module in determining its position (latitude and longitude) by matching them against an onboard moon reference map.
This mission, if it turns out to be fruitful, will make India the only country to have marked its presence on the lunar south pole which is considered to be difficult for its rough and harsh conditions, and fourth – after US, China, and Russia – to have successfully landed on the moon’s surface.
The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14. 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.
Ever since the July 14 launch, ISRO has been maintaining that the health of the spacecraft remains “normal”.
On August 5, Chandrayaan-3 was successfully inserted into the lunar orbit with multiple key manoeuvres thereafter. 
Later on August 17, the mission marked another giant leap in its lunar quest as the 'Vikram' lander module of the spacecraft successfully separated from the propulsion module on Thursday. 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. 
Then the deboosting of the Lander module was undertaken in two phases. Deboosting is the process of slowing down to position itself in an orbit where the orbit's closest point to the Moon is. 
The stated objectives of Chandrayaan-3, India's third lunar mission, are safe and soft landing on the lunar surface, rover moving 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-2 mission was only “partially successful” since the lander lost contact after a hard landing, but the ISRO earlier this week successfully established two-way communication between the Chandrayaan-3 lander module and the still orbiting Chandrayaan-2 orbiter.
