India took a big step forward on Wednesday night when the Chandrayaan-3 lander effectively landed on the moon’s south pole, becoming the first country to achieve this historic feat and ending the sadness caused by the crash landing. Chandrayaan-2, 4 years ago.
Officials at the headquarters of India’s local company ISRO in Bangalore applauded after the Vikram began its motorized vertical descent to its landing site.
“India is on the moon!” said Prime Minister Narendra Modi, who is recently attending the 15th BRICS summit in Johannesburg. He watched the broadcast and as soon as he knocked, he put on a big smile and waved the tricolor flag.
The countdown to the Vikram oscillated to 150 meters, then 130 meters, 50 meters and slowed as it approached the lunar service before landing on the lunar surface.
When the Vikram lander carrying the Pragyaan rover in its abdomen landed on the lunar surface, it marked a huge leap in India’s space journey, providing a well-deserved end to ISRO’s long years of work.
This makes India the fourth country (after the US, China and Russia) to have effectively landed on the surface of the Moon and achieved a position in the record books as the first to land on the south face of Earth’s natural satellite.
Billions of people across India and around the world are intensely following the long-awaited event, especially after Russia’s Luna-25 spacecraft crashed on Sunday after squandering control.
As the planned comfortable landing of Chandrayaan-3 approached, other people across the country prayed to God in all religions and places of worship for the mission. Special projections of the comfortable landing were held throughout the country, adding schools, scientific centers and public institutions. ISRO conducted the moves live on ISRO’s website, its YouTube channel, Facebook and public broadcaster DD National TV.
The expected time for the comfortable landing of Chandrayaan-3 at the south pole of the Moon on August 23, 2023 (Wednesday) at 6:04 p. m. IST, with the motorized descent of the Vikram lander at 5:45 p. m. IST.
ISRO has published a series of close-up photographs of the moon, helping the lander determine its position (latitude and longitude) by comparing them to a lunar reference chart on board.
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 very different and more complicated terrain than that of the equatorial region.
The spacecraft was introduced from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, on July 14. A GSLV Mark 3 (LVM 3) heavy launcher used for the release of the spacecraft that was placed in lunar orbit on the fifth of August and has since been lowered closer to the moon’s surface by a series of orbital maneuvers.
Since the July 14 launch, ISRO has said the spacecraft’s prestige remains “normal. “On August 5, Chandrayaan-3 was effectively inserted into lunar orbit with several key maneuvers thereafter.
Then, on Aug. 17, the project marked a giant leap in its lunar quest when the spacecraft’s “Vikram” lander effectively separated from the propulsion module on Thursday. The lander of the Chandrayaan-3 project is named after Vikram Sarabhai (1919-1971). ), widely regarded as the father of the Indian regional programme.
Then, the deceleration of the Lander module is done in two phases. Deceleration is the deceleration procedure to position oneself in an orbit where the point of the orbit closest to the Moon is located.
The stated goals of Chandrayaan-3, India’s third lunar mission, were a soft landing on the lunar surface, moving the rover across the lunar surface, and in situ scientific experiments.
Upon landing, the lander and rover were scheduled to operate for one lunar day. One day on the Moon is equivalent to 14 days on Earth. The progression phase of Chandrayaan-3 began in January 2020, and its launch is planned for 2021.
However, the Covid-19 pandemic has unexpectedly slowed down the mission. The approved cost of the Chandrayaan-3 is Rs 250 crore (not including the cost of the launcher).
The Chandrayaan-2 project was only “partially successful” as the lander lost contact after a hard landing, but ISRO earlier this week managed to identify two-way communication between the Chandrayaan-3 lander and the Chandrayaan-2 orbiter still in orbit.
The founder of the Indian Space Research Organization (ISRO), Vikram Sarabhai, considered the father of India’s space program, once said that India will have to be an unprecedented country in applying complex technologies to the real upheavals facing society.
The status quo of ISRO is one of Vikram Sarabhai’s greatest achievements. He managed to convince the government of the day of the importance of a regional program for an emerging country like India.
