Chandrayaan-3: Spacecraft Lifts Off Successfully From Sriharikota

By LokMarg

The wait is over as Chandrayaan-3 was launched on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota as per scheduled launch time.

The journey from Earth to the moon for the spacecraft is estimated to take about a month and the landing is expected on August 23. Upon landing, it will operate for one lunar day, which is approximately 14 Earth days. One day on the Moon is equal to 14 days on Earth.
Chandrayaan-3, India’s third lunar exploration mission, will make India the fourth country after US, China, and Russia, to land its spacecraft on the surface of the moon and demonstrate the country’s abilities for safe and soft landing on lunar surface.

Chandrayaan-3 is the ISRO’s follow-up attempt after the Chandrayaan-2 mission faced challenges during its soft landing on the lunar surface in 2019 and was eventually deemed to have failed its core mission objectives.

Chandrayaan-3 will be inserted into the Lunar Transfer Trajectory after the orbit raising maneuvers. Covering a distance of over 300,000 km, it will reach the Moon in the coming weeks. Scientific instruments onboard will study the Moon’s surface and enhance our knowledge.

Chandrayaan-3 is equipped with a lander, a rover and a propulsion module. It weighs around 3,900 kilograms.

Moon serves as a repository of the Earth’s past and a successful lunar mission by India will help enhance life on Earth while also enabling it explore the rest of the solar system and beyond.

July 14, 2023 will always be etched in golden letters in the annals of India’s space sector history, said Prime Minister Narendra Modi, ahead of the launch of much-awaited Chandrayaan-3, India’s third lunar mission.

“This remarkable mission will carry the hopes and dreams of our nation,” PM Modi had tweeted earlier.

“Thanks to our scientists, India has a very rich history in the space sector. Chandrayaan-1 is considered to be a path breaker among global lunar missions as it confirmed the presence of water molecules on the moon. It featured in over 200 scientific publications around the world,” PM Modi wrote on Twitter.

“Till Chandrayaan-1, the moon was believed to be a bone-dry, geologically inactive and uninhabitable celestial body. Now, it is seen as a dynamic and geologically active body with the presence of water and sub-surface ice,” he added, asserting it might be potentially inhabited in the future.

Chandrayaan-2 was equally pathbreaking because data from the Orbiter associated with it detected the presence of chromium, manganese and sodium for the first time through remote sensing. This will also provide more insights into the moon’s magmatic evolution, PM Modi stated.

The key scientific outcomes from Chandrayaan-2 include the first ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument and more. The mission has featured in almost 50 publications.

Extending best wishes for the Chandrayaan-3 mission, PM Modi urged people to know more about this lunar mission and the strides India has made in space, science and innovation. “It will make you all very proud,” he added.

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.

K Sivan, former director of ISRO, told ANI that the success of mission Chandrayan-3 will give a morale boost to programmes like Gaganyan, India’s first manned space mission.

Former ISRO scientist Nambi Narayanan, who has been instrumental in the country’s space sector innovation, said on Thursday the Chandrayaan-3 mission is going to be successful and a game-changer event for India.

”Chandrayaan-3 will definitely be a game changer for India and I hope it will be successful. India will become an inspiration to the entire world. Let’s wait for the launch and pray for the best,” Nambi Narayanan told ANI.

“I’m assuming, and I hope that it will be a successful mission. Because whatever the problem in Chandrayaan-2, actually, we corrected the whole thing. From the failure, we have understood all mistakes (on our part),” Narayanan, the recipient of India’s third highest civilian honour, ‘Padma Bhushan’, told ANI.(ANI)

Chandrayaan-3 countdown

Chandrayaan-3 Mission Countdown Begins Tomorrow

By LokMarg

Chandrayaan-3, India’s third lunar exploration mission, will make India the fourth country to land its spacecraft on the surface of the moon and demonstrate the country’s abilities for safe and soft landing on lunar surface.

The countdown for the launch of mission will begin on Thursday ahead of take off on Friday from the Satish Dhawan Space Centre in Sriharikota.

“Mission Readiness Review is completed. The board has authorised the launch. The countdown begins tomorrow,” ISRO said in a tweet.

It will be launched on a GSLV Mark 3 (LVM 3) heavy lift launch vehicle

This will be Indian Space Research Organisation’s (ISRO) follow-up attempt after Chandrayaan-2 mission faced challenges during its soft landing in 2019.

The ‘Launch Rehearsal’ simulating the entire launch preparation and process has been concluded by the ISRO.

If all goes well, Chandrayaan-3 will be the first spacecraft to land on Moon’s South Pole, demonstrating India’s technical prowess and bold spacefaring ambitions.

Chandrayaan-3 mission will demonstrate safe and soft landing on lunar surface, rover roving on the moon and conduct in-situ scientific experiments.

ISRO invited citizens to witness the launch of the much-awaited Chandrayaan-3 from the viewing gallery at Sriharikota.

During Chandrayaan-2 mission, ISRO lost contact with the lander when it was just a notch away from the moon’s surface.

The journey from earth to the moon for the to-be-launched spacecraft is estimated to take around a month and the landing is expected on August 23. Upon landing, it will operate for one lunar day, which is approximately 14 earth days. One day on Moon is equal to 14 days on earth.

K Sivan, former director of ISRO, told ANI that success of mission Chandrayan-3 will give a morale boost to programs like Gaganyan.

“We understood what went wrong with Chandrayan-2 when we could not land on the moon surface, we recreated the failure modes and we ensured that this time we have success. The challenge is the same as Chandrayan-2, same environment for landing. This time we hope that we have done enough based on the lesson of Chandrayan-2 that gives us more confidence. In space there are always unknown unknowns…hope that all issues are addressed and that we emerge with success,” he said.

“We are getting tech landing on a celestial body. By landing successfully, we will acquire landing technology and it will be good for future generations. A number of scientific experiments are planned and scientists will have more knowledge of moon’s geology and earth’s origin,” he added.

Mylswamy Annadurai, Mission Director of Chandrayaan-1, said Chandrayaan-3 is a very important mission.

“We have shown that we can orbit, but we could not do a soft landing, By doing so this time we can show that Chandrayan-1 was not an isolated success. Internationally, the world is looking back to the moon, the real seeding for that came from Chandrayaan-1. So we need to make this mission successful,” he told ANI.

“Hard lessons were learnt from Chandrayaan 1 and 2. At every step, we are supposed to have a plan B. There were some setbacks in Chandrayaan- 2. This time we are back on track. We are clear on what we want to do and it will ensure we can softly land on the surface of the moon. Target of landing is also larger, all elements have been tested multiple times, we hope this is a success…,” he added.

Chandrayaan-3’s development phase commenced in January 2020 with plans to launch it somewhere in 2021, but the COVID-19 pandemic caused delays in the development process.

The major discovery of the Chandrayaan-1 mission, launched in 2008, is the detection of water (H2O) and hydroxyl (OH) on the lunar surface. Data also revealed their enhanced abundance towards the polar region.

“The primary science objective of the mission was to prepare a three dimensional atlas of both near and far side of the Moon and to conduct chemical and mineralogical mapping of the entire lunar surface with high spatial resolution,” Vikram Sarabhai Space Centre under ISRO had said.

Moon serves as a repository of earth’s past and a successful lunar mission by India will help in enhancing life on Earth and prepare to explore the rest of the solar system — and beyond.

Director of Indian Space and Research Organisation (ISRO), S Somanath, had said that if everything goes well, the spacecraft will land on the moon on August 23.

The date has been decided based on sunrise on the moon but if it gets delayed, then landing may take place next month, he said.  (ANI)
