New Delhi: 140 crore Indians have kept their fingers crossed as D-day approaches for the much-awaited soft landing of the country\u2019s third moon mission \u2014 Chandrayaan-3. People across the country are praying to God for a successful ISRO mission. The scheduled timing for the soft landing of Chandrayaan-3 on the moon\u2019s south pole on August 23, 2023 (Wednesday), is around 18:04 IST, with the powered descent of Vikram lander expected at 1745 IST.<\/p>\n
The live telecast of the landing operations at Mission Operation Complex (MOX) will begin at 1720 IST on Wednesday. Live actions of 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.<\/p>\n
In its latest update on Chandrayaan-3 soft landing, ISRO has said the mission is on schedule and systems are undergoing regular checks. It also released a series of up-close images of the moon. These images assist the lander module in determining its position (latitude and longitude) by matching them against an onboard moon reference map.<\/p>\n
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 \u2013 after the US, China, and Russia \u2013 to have successfully landed on the moon\u2019s surface.<\/p>\n
Historically, spacecraft missions to the Moon have primarily targeted the equatorial region due to its favorable terrain and operating conditions. However, the lunar south pole presents a vastly different and more challenging terrain compared to the equatorial region. With all eyes on the attempted Chandrayaan-3 soft landing, more so after Russia\u2019s Luna-25 failed recently, let us look at the sequence of India\u2019s mission since its lift-off 41 days ago.<\/p>\n
The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh\u2019s 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 maneuvers been lowered closer to the moon\u2019s surface.<\/p>\n
Ever since the July 14 launch, ISRO has been maintaining that the health of the spacecraft remains \u201cnormal\u201d.
\nOn August 5, Chandrayaan-3 was successfully inserted into the lunar orbit with multiple key maneuvers thereafter. Then on August 17, the mission marked another giant leap in its lunar quest as the \u2018Vikram\u2019 lander module of the spacecraft successfully separated from the propulsion module on Thursday. The Chandrayaan-3 mission\u2019s lander is named after Vikram Sarabhai (1919\u20131971), who is widely regarded as the father of the Indian space program.<\/p>\n
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\u2019s closest point to the Moon is. The stated objectives of Chandrayaan-3, India\u2019s third lunar mission, are safe and soft landing on the lunar surface, rover moving on the moon\u2019s surface, and in-situ scientific experiments. The approved cost of Chandrayaan-3 is Rs 250 crores (excluding launch vehicle cost).<\/p>\n
Chandrayaan-3\u2019s 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\u2019s progress. Astro-scientists say that the partially successful Chandrayaan-2 mission will help the Chandrayaan-3 mission, as the former had mapped the moon\u2019s surface to perfection, and added those maps could now be used for soft landing.<\/p>\n
Speaking to ANI, astronomer Priya Hasan said the previous lunar mission \u2013 Chandrayaan-2 \u2013 has helped the ongoing mission and explained how the orbiter of the Chandrayaan-2, which is still orbiting around the moon, is helping the crucial part of the Chandrayaan-3 mission. Chandrayaan-2 mission was only \u201cpartially successful\u201d 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
