Chandrayaan-3 Moon Landing: ISRO Scripts History as India Becomes First to Land on Lunar South Pole

In a giant leap for its space programme, India’s Moon mission Chandrayaan-3 touched down on the lunar south pole at 6.04pm on Wednesday, propelling the country to an exclusive club of four and making it the first country to land on the uncharted surface.

India scripted history as ISRO’s ambitious third Moon mission Chandrayaan-3’s Lander Module (LM) touched down on the lunar surface on Wednesday, making it only the fourth country to accomplish the feat, and first to reach the uncharted south pole of Earth’s only natural satellite.

In a big boost to India’s space prowess, the LM comprising the lander (Vikram) and the 26kg rover (Pragyan), made the soft landing near the south polar region of the Moon at 6.04pm, less than a week after a similar Russian lander crashed.

With this touchdown on moon in second attempt in four years, India has become the fourth country to master the technology of soft-landing on the lunar surface after the US, China and the erstwhile Soviet Union.

Chandrayaan-3 is a follow-on mission to Chandrayaan-2 and its objectives are to demonstrate safe and soft-landing on the lunar surface, roving on the Moon, and to conduct in-situ scientific experiments.

Chandrayaan-2 had failed in its lunar phase when its lander ‘Vikram’ crashed into the surface of the Moon minutes before the touch down following anomalies in the braking system in the lander while attempting a landing on September 7, 2019. Chandrayaan’s maiden mission was in 2008.

The Rs 600 crore Chandrayaan-3 mission was launched on July 14 onboard Launch Vehicle Mark-III (LVM-3) rocket, for a 41-day voyage to reach near the lunar south pole.

The soft-landing took place days after Russia’s Luna-25 spacecraft crashed into the Moon after spinning out of control.

The lander and the six-wheeled rover (with total mass of 1,752 kg) are designed to operate for one lunar daylight period (about 14 Earth days) The lander with four legs, had multiple sensors to ensure a safe touchdown, including an accelerometer, altimeters, Doppler velocimeter, inclinometer, touchdown sensor, and a suite of cameras for hazard avoidance and positional knowledge.

The lander carries the rover in a compartment with a ramp for deployment onto the surface.

Chandrayaan-3’s Lander Module Set for Automatic Landing Sequence, Says ISRO

ISRO on Wednesday said it is all set to initiate the Automatic Landing Sequence (ALS) for its ambitious third Moon mission Chandrayaan-3‘s Lander Module (LM) to touch down on the lunar surface this evening.

The LM comprising the lander (Vikram) and the rover (Pragyan) is scheduled to make a touchdown near the south polar region of the Moon at 6:04 pm on Wednesday, a feat not achieved by any country so far.

“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 (5:44 pm),” ISRO said in a post on X.

“Upon receiving the ALS command, the LM activates the throttleable engines for powered descent. The mission operations team will keep confirming the sequential execution of commands,” it said.

After checking all the parameters and deciding to land, ISRO will upload the required commands from its Indian Deep Space Network (IDSN) facility at Byalalu near here, to the LM, a few hours before the scheduled touchdown time.

According to ISRO officials, for landing, at around 30 km altitude, the lander enters the powered braking phase and begins to use its four thruster engines by “retro firing” them to reach the surface of the moon, by gradually reducing the speed. This is to ensure the lander doesn’t crash, as the Moon’s gravity will also be in play.

On reaching an altitude of around 6.8 km, only two engines will be used, while the two others will be shut down, aimed at giving the reverse thrust to the lander as it descends further, they said.

Then, on reaching an altitude of about 150-100 metres, the lander, using its sensors and cameras, would scan the surface to check whether there are any obstacles and then start descending to make a soft landing.

ISRO Chairman S Somanath had recently said the most critical part of the landing will be the process of reducing the velocity of the lander from 30 km height to the final landing, and the ability to reorient the spacecraft from horizontal to vertical direction. “This is the trick we have to play here,” he said.

After the soft landing, the rover will descend from the lander’s belly, onto the Moon’s surface, using one of its side panels, which will act as a ramp. On landing the lander may have to face the challenge of lunar dust due to the firing of onboard engines close to the moon’s surface.

The lander and rover will have a mission life of one lunar day (about 14 earth days) to study the surroundings there. However, ISRO officials do not rule out the possibility of them coming to life for another lunar day.

Chandrayaan-3 Lunar Landing Countdown Begins: When and Where to Watch the Live Streaming

Chandrayaan-3, India’s latest lunar mission, is expected to make a soft landing on the south pole of the moon on August 23. The spacecraft was launched by Indian Space Research Organisation (ISRO) on July 14. After completing a journey of almost 40 days, the Chandrayaan-3 mission will finally make India the fourth nation to land on moon with its successful landing on Wednesday. A day ahead of the expected landing, ISRO has confirmed that the mission is right on schedule and will be attempting landing as per planned.

India has high hopes from Chandrayaan-3 mission, especially after its partial success with the last lunar mission, Chandrayaan-2. As the countdown to Chandrayaan-3 landing begins, ISRO has already announced to livestream the historic event, which will begin at around 5:20 PM IST on August 23. The estimated landing time is expected to be 6:04 PM IST.

Chandrayaan-3 lunar landing: When and where to watch the live streaming

ISRO will be live streaming the lunar landing of Chandrayaan-3 on various social media channels. The event can be watched on ISRO’s official website, ISRO’s YouTube channel and the Facebook page of the organisation. The streaming will begin at 5:20 PM IST, around 30 minutes before the expected landing time.

Meanwhile, the live telecast of the landing will be available on DD National TV. Viewers can also watch the following space for the live streaming of the Chandrayaan-3 lunar landing. 

 

Chandrayaan- 3 was launched on July 14 at 2.35 PM IST onboard Launch Vehicle Mark-III (LVM-3) rocket from Sriharikota. If it successfully lands as planned tomorrow, India will become the first country to reach the uncharted south pole of Moon. 

ISRO officials earlier noted that the mission life of the Chandrayaan- 3 lander is one lunar day, which is equal to 14 Earth days. During the journey, ISRo has also released several pictures of the moon as captured by Chandrayaan-3.

Chandrayaan-3 Landing Could Be Shifted to August 27 if Factors Unfavourable on August 23: ISRO Scientist

If any factor regarding the lander module appears unfavourable, then the landing will be shifted to August 27, said the Space Applications Centre-ISRO about Chandrayaan-3 on Monday. 

Nilesh M Desai, director of Space Applications Centre-ISRO, Ahmedabad said that the decision regarding the landing will be taken based on the health of the lander module and the conditions on the Moon.

“On August 23, two hours before Chandrayaan-3 lands on the Moon, we will decide on whether or not it will be appropriate to land it at that time based on the health of the lander module and the conditions on the Moon. In case, if any factor appears to be not favourable, then we will land the module on the Moon on August 27. No problem should occur and we will be able to land the module on August 23,” Director Desai said.

ISRO Chairman and Secretary Department of Space S Somanath called on the Union Minister of State (Independent Charge) Science and Technology, Atomic Energy and Space Jitendra Singh in New Delhi today and apprised him of the status and readiness of ‘Chandrayaan-3′ for the moon landing scheduled on August 23, 2023.

Chairman ISRO briefed the minister on the health status of Chandrayaan-3 and said that all systems are working perfectly and no contingencies are anticipated on Wednesday.

In the next two days, the health of Chandrayaan-3 will be continuously monitored. The final sequence of landing will be loaded two days ahead and tested out, he said.

During the meeting, Minister Jitendra Singh expressed his confidence in ‘Chandrayaan-3′ making a soft landing this time and hoped that it will script a new history of planetary exploration under the guidance of Prime Minister Narendra Modi.

ISRO said the Chandrayaan-3 is set to land on the moon on August 23, 2023, around 18:04 hours IST.

Live actions 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.

While the Chandrayaan-2 mission was only “partially successful” since the lander lost contact after a hard landing, the ISRO successfully established two-way communication between the Chandrayaan-3 lander module and the still-orbiting Chandrayaan-2 orbiter. In a significant development, the Chandrayaan-2 orbiter which was already fixed around the moon established a two-way connection with the lander module of Chandrayaan-3 on Monday.

Earlier today, the ISRO shared new images of the lunar far side area captured by the Chandrayaan-3.

India will be the fourth country in the world to achieve this feat after the United States, Russia, and China, but India will be the only country in the world to land on the lunar south pole.

The primary objectives of the Chandrayaan-3 mission are threefold — to demonstrate safe and soft landing on lunar surface; to demonstrate rover roving on the moon, and to conduct in-situ scientific experiments.

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.

Jitendra Singh recalled that the first in the series of Chandrayaan — namely Chandrayaan-1, is credited for having discovered the presence of water on the surface of the Moon, which was a new revelation for the world and even the premier Space agencies like the USA’s NASA (National Aeronautics and Space Administration) were fascinated by this discovery and used the inputs for their further experiments.

Chandrayaan-3 mission was launched on July 14, 2023, via the GSLV Mark 3 (LVM 3) heavy-lift launch vehicle from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota at 2:35 PM.

Ahead of the much-awaited soft landing of Chandrayaan-3 on the south pole of the Moon, former director of the Indian Space Research Organisation (ISRO) and in-charge of the previous lunar mission ‘Chandrayaan-2′, K Sivan earlier today said that the mission will be a “grand success”.

“It’s a very anxious moment…I’m sure that this time it will be a grand success,” Sivan said while speaking to ANI.

“We have our own system and we will be establishing a soft landing without any problem. But it is a complex process,” he said while responding to a question asked whether there would be any impact after the failure of Russia’s Luna-25 mission. Russia’s moon mission failed after its Luna-25 spacecraft spun out of control and smashed into the moon on Sunday.

He said that corrective measures have been taken after going through data generated by the Chandrayaan-2 mission. When asked if those additional systems too were indigenous, Sivan said, “Everything is indigenous.”

Earlier today, ISRO released images of the lunar far side area captured by the Lander Hazard Detection and Avoidance Camera (LHDAC). This camera assists in locating a safe landing area — without boulders or deep trenches — during the descent.

Notably, the ‘Vikram’ lander module of the spacecraft successfully separated from the propulsion module recently, and subsequently underwent crucial deboosting manoeuvres and descended to a slightly lower orbit. The Chandrayaan-3 mission’s lander is named after Vikram Sarabhai (1919–1971), who is widely regarded as the father of the Indian space program.

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.

It has been a month and seven days since the Indian Space Research Organisation launched the Chandrayaan-3 mission on July 14. The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota.

The stated objectives of Chandrayaan-3, India’s third lunar mission, are safe and soft landing, rover roving 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.

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.

Luna-25, Russia’s First Moon Mission in 47 Years, Ends in Failure After Crashing on Lunar Surface

Russia’s first moon mission in 47 years failed when its Luna-25 space craft spun out of control and crashed into the moon after a problem preparing for pre-landing orbit, underscoring the post-Soviet decline of a once mighty space programme.

Russia’s state space corporation, Roskosmos, said it had lost contact with the craft at 11:57 GMT (5:27pm IST) on Saturday after a problem as the craft was shunted into pre-landing orbit. A soft landing had been planned for Monday.

“The apparatus moved into an unpredictable orbit and ceased to exist as a result of a collision with the surface of the Moon,” Roskosmos said in a statement.

It said a special inter-departmental commission had been formed to investigate the reasons behind the loss of the Luna-25 craft, whose mission had raised hopes in Moscow that Russia was returning to the big power moon race.

The failure underscored the decline of Russia’s space power since the glory days of Cold War competition when Moscow was the first to launch a satellite to orbit the Earth – Sputnik 1, in 1957 – and Soviet cosmonaut Yuri Gagarin became the first man to travel into space in 1961.

It also comes as Russia’s $2 trillion (roughly Rs. 1,66,18,000 crore) economy faces its biggest external challenge for decades: the pressure of both Western sanctions and fighting the biggest land war in Europe since World War Two.

Though moon missions are fiendishly difficult, and many US and Soviet attempts have failed, Russia had not attempted a moon mission since Luna-24 in 1976, when Communist leader Leonid Brezhnev ruled the Kremlin.

Russian state television put news of the loss of Luna-25 at number 8 in its line up at noon and gave it just 26 seconds of coverage, after a news about fires on Tenerife and a 4 minute item about a professional holiday for Russian pilots and crews.

Failed Moonshot

Russia has been racing against India, whose Chandrayaan-3 spacecraft is scheduled to land on the moon’s south pole this week, and more broadly against China and the United States which both have advanced lunar ambitions.

As news of the Luna-25 failure broke, the Indian Space Research Organisation (ISRO) posted on X, formerly Twitter, that Chandrayaan-3 was set to land on August 23.

Russian officials had hoped that the Luna-25 mission would show Russia can compete with the superpowers in space despite its post-Soviet decline and the vast cost of the Ukraine war.

“The flight control system was a vulnerable area, which had to go through many fixes,” said Anatoly Zak, the creator and publisher of www.RussianSpaceWeb.com which tracks Russian space programmes.

Zak said Russia had also gone for the much more ambitious moon landing before undertaking a simpler orbital mission – the usual practice for the Soviet Union, the United States, China and India.

While Luna-25 went beyond the earth’s orbit – unlike the failed 2011 Fobos-Grunt mission to one of the moons of Mars – the crash could impact Russia’s moon programme, which envisages several more missions over coming years including a possible joint effort with China.

Russian scientists have repeatedly complained that the space programme has been weakened by poor managers who are keen for unrealistic vanity space projects, corruption and a decline in the rigour of Russia’s post-Soviet scientific education system.

“It is so sad that it was not possible to land the apparatus,” said Mikhail Marov, a leading Soviet physicist and astronomer.

Marov, 90, was hospitalised in Moscow after news of the failure of Luna-25 was announced, although details of what he was ill with were not available.

Marov told the Moskovsky Komsomolets newspaper that he hoped the reasons behind the crash would be discussed and examined rigorously.

“This was perhaps the last hope for me to see a revival of our lunar program,” he said.

Luna-25 Spacecraft Made Adjustments While Attempting to Prepare for Landing on Lunar Surface

Russia’s Luna-25 spacecraft adjusted its orbit on Friday as it prepared to attempt the first landing near the south pole of the moon, space agency Roscosmos said.

“Today at 09:20 Moscow time (11:50 am IST), the propulsion system of the automatic station performed an orbit correction lasting 40 seconds. Its goal is to provide the best conditions for the subsequent construction of a pre-landing orbit,” Roscosmos said in a statement.

It said the adjustment went smoothly and the spacecraft’s onboard systems and communications were all functioning normally. The space agency also released an image of moon shared by Luna-25 on August 17.

Russian space chief Yuri Borisov said last week that Luna-25 aimed to land on August 21.

An Indian spacecraft, Chandrayaan-3, is also orbiting the moon in readiness for a landing near the south pole, where scientists believe there are significant quantities of frozen water that could support a human presence there in the future.

Much is riding on the success of Russia’s first lunar mission in 47 years, with Moscow attempting to prove that it is still a leader in space exploration despite the huge costs of the war in Ukraine and Western sanctions aimed at curbing its access to technology.

Luna-25 was launched from the Ruusia’s Vostochny spaceport on August 11, 2023 aboard Soyuz 2.1v rocket. The lander is expected to touch down on the moon on August 21. On the other hand, ISRO’s Chandrayaan-3 was launched from the Satish Dhawan Space Centre in Sriharikota, on board the LVM-3 rocket. The lander is expecting its touchdown on lunar surface on August 23.

Chandrayaan-3’s Vikram Lander to Undergo Deboosting Manoeuvre: Details

Chandrayaan-3’s Vikram lander is set to undergo a crucial deboosting manoeuvre on Friday after successfully getting separated from the propulsion module a day before. The deboosting manoeuvre is scheduled today at around 4 PM IST. Deboosting is the process of slowing down to position itself in an orbit where the orbit’s closest point to the Moon (Perilune) is 30 km and the farthest point (the Apolune) is 100 km. 

“The next Lander Module (Deorbit 1) manoeuvre is scheduled for tomorrow (August 18, 2023) around 1600 hrs IST,” ISRO posted on X (formerly Twitter) yesterday while announcing the successful separation of the lander from the propulsion module.

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. On Wednesday, the spacecraft carried out the final lunar-bound orbit reduction manoeuvre of the Chandrayaan-3 spacecraft, a week ahead of its scheduled landing on the south pole of the moon on August 23.

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.

It has been a month and three days since the Indian Space Research Organisation launched the Chandrayaan-3 mission on July 14. The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota. ISRO is bidding to make a successful soft landing on the moon, which will make India the fourth country in the world to achieve the feat after the United States, Russia, and China.

The stated objectives of Chandrayaan-3, India’s third lunar mission, are safe and soft landing, rover roving 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-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.

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.

During the Chandrayaan-1 mission, the satellite made more than 3,400 orbits around the moon and the mission was concluded when the communication with the spacecraft was lost on August 29, 2009, according to the Indian Space Research Organisation (ISRO).

Meanwhile, the Chairman of the Indian Space Research Organisation (ISRO), S Somanath last week expressed confidence in the progress of the Chandrayaan 3, providing reassurance that all systems were operating as planned. Chairman S Somanath stated, “Everything is going fine now. There will be a series of manoeuvres until it lands (on the Moon) on 23rd August. The satellite is healthy.”

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 to explore the rest of the solar system and beyond.

Historically, spacecraft missions to the Moon have primarily targeted the equatorial region due to its favourable terrain and operating conditions. However, the lunar south pole presents a vastly different and more challenging terrain compared to the equatorial region.

Chandrayaan-3 Spacecraft Achieves ‘Near-Circular Orbit’ Around Moon After Performing Another Manoeuvre

India’s ambitious third Moon mission’s spacecraft Chandrayaan-3 on Monday underwent another manoeuvre, bringing it even closer to the Lunar surface, ISRO said.

The national space agency headquartered here said the spacecraft has now achieved a “near-circular orbit” around the moon.

Post its launch on July 14, Chandrayaan-3 entered into the lunar orbit on August 5, following which two orbit reduction manoeuvres were carried out on August 6 and 9.

“Orbit circularisation phase commences. Precise manoeuvre performed today has achieved a near-circular orbit of 150 km x 177 km,” ISRO said in a tweet.

The next operation is planned for August 16, around 8:30 am, it said.

As the mission progresses, a series of manoeuvres are being conducted by ISRO to gradually reduce Chandrayaan-3’s orbit and position it over the lunar poles.

According to ISRO sources, one more manoeuvre will be performed on the spacecraft on August 16 to reach 100 km orbit, following which the landing module, comprising the lander and rover will break away from the propulsion module.

After this, the lander is expected to undergo a “deboost” (the process of slowing down) and make a soft landing on the south polar region of the Moon on August 23.

Last week, ISRO Chairman S Somnath said the most critical part of the landing is the process of bringing the velocity of the lander from 30 km height to the final landing, and that the ability to transfer the spacecraft from horizontal to vertical direction is the “trick we have to play” here.

He said, “The velocity at the start of the landing process is almost 1.68 km per second, but this speed is horizontal to the surface of the moon. The Chandrayaan 3 here is tilted almost 90 degrees, it has to become vertical. So this whole process of turning from horizontal to vertical is a very interesting calculation mathematically. We have done a lot of simulations. It is here where we had the problem last time (Chandrayaan 2).” Further, it has to be ensured that fuel consumption is less, the distance calculation is correct, and all the algorithms are working properly.

“Extensive simulations have gone, guidance design has been changed, and a lot of algorithms have been put in place to make sure that in all these phases required dispersions are handled….to attempt to make a proper landing,” he said.

Over five moves in the three weeks since the July 14 launch, ISRO had lifted the Chandrayaan-3 spacecraft into orbits farther and farther away from the Earth. 

Then, on August 1 in a key manoeuvre — a slingshot move — the spacecraft was sent successfully towards the Moon from Earth’s orbit. Following this trans-lunar injection, the Chandrayaan-3 spacecraft escaped from orbiting the Earth and began following a path that would take it to the vicinity of the moon.

Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface.

It comprises an indigenous propulsion module, a lander module, and a rover with the objective of developing and demonstrating new technologies required for inter-planetary missions.

The propulsion module will carry the lander and rover configuration till the 100 km lunar orbit. The propulsion module has a Spectropolarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and polarimetric measurements of Earth from the lunar orbit.

The mission objectives of Chandrayaan-3 are to demonstrate a safe and soft landing on the lunar surface, to demonstrate rover roving on the Moon, and to conduct in-situ scientific experiments.

The lander will have the capability to soft land at a specified lunar site and deploy the rover that will carry out in-situ chemical analysis of the Moon’s surface during the course of its mobility.

The lander and the rover have scientific payloads to carry out experiments on the lunar surface.

ISRO Releases First Images of Moon Captured by Chandrayaan-3 After Entering Lunar Orbit

The Indian Space Research Organisation (ISRO) on Sunday put out the first images of the moon as captured by Chandrayaan-3, India’s third lunar mission.

Chandrayan-3 captured the stunning images of the lunar surface after entering the Moon’s orbit on Saturday.

“The Moon, as viewed by #Chandrayaan3 spacecraft during Lunar Orbit Insertion (LOI) on August 5, 2023,” tweeted the Mission’s official Twitter handle.

The Chandrayaan-3 spacecraft, which covered about two-thirds of the distance to the Moon since its launch, successfully entered into the Lunar orbit on Saturday, according to ISRO.

The spacecraft, mounted on GSLV Mark 3 (LVM 3) heavy-lift launch vehicle, successfully lifted off from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on July 14.

India became only the fourth country after the US, China, and Russia to land its spacecraft on the surface of the moon, demonstrating the country’s ability for a safe and soft landing on the lunar surface.

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.

The approved cost of Chandrayaan-3 is Rs 250 crore (Excluding Launch Vehicle Cost).

Chandrayaan-3’s development phase commenced in January 2020 with the launch initially planned in 2021. However, the Covid-19 pandemic brought an unforeseen delay to the mission’s progress.

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 Launch Successful, Lander Expected to Land on Moon on August 23

The wait is over as the GSLV Mark 3 (LVM 3) heavy-lift launch vehicle lifted off successfully from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota as per the 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 the 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 to 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 the 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 been 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 programs 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.
