I keep seeing comments from people telling me that the reason for the failure was revealed recently, this is not true, we did get more details on a number of important factors, but there's no clear chain of cause to effect which explains what was seen without speculation. Recently ISRO Chief S Somnath made a number of very helpful comments highlighting: 1) The engine over performance during rough braking resulting in the spacecraft being on a trajectory that would land shorter than intended 2) A landing area which was so small that the over performing braking left the spacecraft trajectory outside this area 3) Software limits on things like vehicle rotation rates So it's clear that when the vehicle transitioned to fine braking mode it was in a situation that left it unable to reach the target site, and somehow the guidance software let the vehicle spin out of control. And saying 'it was a software glitch' is true, but is not that answer that the engineers used when addressing the changes needed for CY3. Some possibilities are: * In trying to solve to a landing solution the software ended up unable to find a solution and just stopped doing anything. * The solution math resulted in mathematical operations which crashed the software or left it in an infinite loop * The solution found was inside the moon and it flew there. * The maneuvers to make up the lost distance, combined with limitations on sensors resulted in a mismatch between actual and predicted attitude. And many more, possible scenarios, to disambiguate we'd need the actual Failure Analysis Committee report but it was never published even after legal challenges in court to get it released.

Like an American once said, we do these things not because they are easy, but because they are hard. I love to see India taking this on. So exciting.

Australian here, cheering them on! That last one was so close!

*Rooting for Chandrayaan 3's success*

I think India nails it this time. That is a country of very smart people and when they fail, they learn from it. I think they get it right this time! Ps…. 8/23/23. Congrats to India!! Knew you would do it! Now show the world some cool images of the moon!

I think it's awesome that India has developed such a promising space program. I wish them good luck and Godspeed! 🎉

Godspeed Chandrayaan 3 - good luck to India and ISRO - 🛸✨

As an Indian , it's heartwarming to see you guys so supportive and happy about Indian Space Programs .

Even though launches are almost a daily occurrence and we take for granted modern space exploration we, seeming, have forgotten how truly impressive it is. The amount engineering, mathematics, chemistry and other physical sciences needed to achieve LEO is staggering, to say nothing of the complexity of achieving a rendezvous with another celestial body. With luck, and engineering, hopefully Chandrayaan 3 is a success.

if ISRO fail 1000 time , we stand with them for 1001 try . we know that science and technology is core of Indian development not only in space but any other field .

I'm hoping for the best too. It took JPL several attempts in the 1960s to land on the Moon. It's not an easy task.

Chandrayaan 3 is very important because LUPEX mission depends on it.

Since Chandrayan3 follows 'failure based design', it has a high chance of soft touchdown.. good luck ISRO and India!

It's really cool to see India progress very fast and vigorous in space.

I am hoping for a successful landing this time of Chandrayaan-3 The biggest collaboration between ISRO and NASA is the NASA-ISRO SAR (NISAR) Mission scheduled for launch on the GSLV mark 2 rocket early in 2024. This synthetic aperture radar system will have two radar wavelengths, 24 cm and 12 cm, on the same spacecraft.

As an Indian, it's really amazing how much everyone was excited for this launch. People at my workplace stopped working until we saw satellite seperation. Awesome to see people take interest in science.

I am so happy for ISRO and the people of India. Good stuff, gets you right in the feels!

Thanks Scott for this excellent breakdown of the Chandrayaan program. Fingers crossed for a successful soft landing this time !

As an Indian fan of Scoot I'm so happy to see you sharing your thoughts ❤ Fly safe Chandrayaan 3

India is going from strength to strength... They are doing the right things at the right time and I am sure India will scale more and more heights. Way to go India.

Kindly note: chandrayaan mission launch on Moon South pole where it doesn't receive sunlight throughout. If successful, India will be the first and only country successfully safe land on moon South pole

The ISRO chief shared minute details about what went wrong with the Vikram lander of Chandrayaan-2 as it went hurtling down towards the identified 500m x 500 m landing spot on the lunar surface with the engines designed to reduce its velocity developing higher thrust than expected. "The primary issues were, one we had five engines which were used to give the reduction of the velocity, which is called the retardation. These engines developed higher thrust than what was expected," he told reporters here on the sidelines of India Space Congress organised by SIA India. Somanath said that when such a higher thrust was happening, the errors on account of this differential were accumulated over some period. "All the errors got accumulated, which was on the higher side than what we had expected. The craft had to make very fast turns. When it started to turn very fast, its ability to turn was limited by the software because we never expected such high rates to come. This was the second issue," the ISRO chief said It was almost close to the ground and kept on increasing the velocity," Mr Somanath said. In a nutshell, the problem in Chandrayaan -2 was that the ability to handle parameter dispersion was very limited, he said.

Godspeed to India and their future space endeavours!

Chandrayaan 2 having a landing failure was heartbreaking... I'm glad to see they've gone and launched another one.

Chandrayaan 1 was the mission which confirmed water traces on Moon. Even when the last attempts were not totally successful, their respective orbiters have provided us with great insights of value.

I am always so excited to see ISRO missions!

After SpaceX, ISRO launches are the most pleasing to watch.

Insha Allah, the Chandrayaan3 mission would be complete success and the orbiter/lander/rover would all succeed in their respective missions. Jai Hind 🇮🇳

You forgot to mention that NASA is watching very closely and hoping for it to succeed because it needs that invaluable data that Chandrayan 3 will collect about the south pole that NASA needs for its Artemis program which aims to land humans on the south pole of the moon.

An amazing achievent for India. I am impressed by the way they did it, and the complexity of the devices.

If they can stick the landing, India will become only the second country after China in the 21st century to soft-land on the moon and that too on the lunar highlands. Amazing.

Safe travels, Chandrayaan 3! The universe is a really big sandbox; plenty of room for us ALL to play in it.

I maybe continents away or even galaxies away but whenever I see an ISRO space module fly past my heart will always swell with pride.

What happened with the lander of the second mission was that during the last phase of it's descent, the thrust produced by the engine was more than estimated. This caused the lander to veer off it's trajectory to the landing area. Now to make it to the landing area, it needed to make a pretty sharp turn, which required it to accelerate. But landing requirements required it to decelerate. This caused a conflicting logic and what the logic circuit decided is unclear, but it looks like it accelerated the rover to restore it's path which led to the hard landing. The new lander has been given more fuel and it's landing area has been expanded significantly. Several other redundancies have been added so that something may work if one thing doesn't. Hope it's successful. Not just for India but for all :)

Good for India! Hoping for the best next time!

It’s so cool to see India’s rise. Very pumped for them in the future

Wishing the best for the Chandrayaan 3 project and the Indian Space Program as a whole. Really inspiring to see the regular folk over there being so supportive and proud of their national science efforts.

“The vehicle somehow ended upside down.” My sympathy. Happens to me all the time in Kerbal Space Program if I don’t pay attention.

Interestingly, the recent name change from GSLV M3 to LVM3 is due, in part, to the fact that the GSLV M3 doesn't have any ancestral link to the older GSLV models. Plus, there's an insurance angle: some previous failures of completely different GSLV configurations reportedly led to increased insurance costs for the GSLV M3. You learn something new every day! INSURANCE.

National pride was the drive behind Apollo missions. It brings high visibility and attract lot of talent. Good luck Chandrayan in the 100 to 0 dash.

Very interesting post. Well done to Scott Manley and the team for reporting on something which isn't SpaceX.😊

I hope we succeed. Thanks to everyone who is rooting for our Chandrayaan, you guys are a gem. ❤❤❤

Best of luck to India! You've got this! ❤

No one is talking about how quick that thing got off the pad? :)

From France, GO India =)

This is awesome. Good luck to the whole team behind this project.

Really want this to succeed, not only because its a space thing, but also for India 🙏

This is cool ! Good job India. Hopefully you’ll accomplish the entire mission !

As a Indian, I'm so happy to see postive response and good wishes by people in comment section, you guys are really nice 😭😭 thank you so much ❤

First orbit raising manoeuvre was successfully done few hrs back. Edit - 2nd to 5th manoeuvre (earth orbit) will be done as follows on- 16,18,20 & 25..

In future, people will NOTE why Interstellar movie mentioned Indian Drones😍

As an American I want this mission to success

Brilliant video! Many, many thanks. Wishing Chandrayaan 3 and India all the very best.

Fantastic! I wish them the best luck! 😃 Thanks, Scott!!! Stay safe there with your family! 🖖😊

The rocket mission director was making multiple references to this rocket being 90% human certified in post launch speech and isro director interrupted him on live steam to hold his horses and said more details to come later, pretty good sign in my opinion.

In an era when, globally, patriotism and nationalism are demeaned and degraded, I love the way space accomplishments always bring people out to express their pride in their countries. Good for India. Her people should take great satisfaction in this achievement which marks her emergence as a great power. Best of luck to all the scientists, engineers and technicians involved and let us hope that the third time is the charm.

Hope it works out. To be honest having a rocket that can take a payload to the moon is impressive enough already. Landing it will be the icing on the cake.

Yeay for India! Rooting for a big success!

My birthday is on August 23rd when this lander is schedules to land so I'll be manually blessing it for a safe landing.

Congrats ISRO for such an incredible program

This is victory for All mankind. Bravo India

Thank you Sccott. I hope it'll brake and not break. ISRO does these missions on a thin shoestring. Kudos to them. Go look up the price.

👉 Chandrayaan-1 discovered water molucles in lunar surface (2008).Chandrayaan-1 was the first Indian lunar probe under the Chandrayaan programme. It was launched by the Indian Space Research Organisation (ISRO) in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft using a PSLV-XL rocket on 22 October 2008 at 00:52 UTC from Satish Dhawan Space Centre, at Sriharikota, Andhra Pradesh. The mission was a major boost to India's space program, as India researched and developed indigenous technology to explore the Moon.The vehicle was inserted into lunar orbit on 8 November 2008. On 14 November 2008, the Moon Impact Probe separated from the Chandrayaan orbiter at 14:36 UTC and struck the south pole in a controlled manner. With this mission, ISRO became the fifth national space agency to reach the lunar surface. Other nations whose national space agencies to have done so prior were the former Soviet Union in 1959,the United States in 1962, Japan in 1993,and ESA member states in 2006. The probe hit near the crater Shackleton at 15:01 UTC.The location of impact was named Jawahar Point. 👉Chandrayaan-2 Chandrayaan-2 was the second lunar exploration mission developed by the Indian Space Research Organisation (ISRO), after Chandrayaan-1. It consisted of a lunar orbiter, a lander, and the Pragyan rover, all of which were developed in India. The main scientific objective was to map and study the variations in lunar surface composition, as well as the location and abundance of lunar water. The spacecraft was launched from the second launch pad at the Satish Dhawan Space Centre in Andhra Pradesh on 22 July 2019 The craft reached the Moon's orbit on 20 August 2019 and began orbital positioning manoeuvres for the landing of the Vikram lander. The lander and the rover were scheduled to land on the near side of the Moon, in the south polar region at a latitude of about 70° south on 6 September 2019. The lander crashed when it deviated from its intended trajectory while attempting to land on 6 September 2019. According to a failure analysis report submitted to ISRO, the crash was caused by a software glitch. Objectives The primary objectives of the Chandrayaan-2 lander were to demonstrate the ability to soft-land and operate a robotic rover on the lunar surface. The scientific goals of the orbiter were: to study lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.[51][52] to study the water ice in the south polar region and thickness of the lunar regolith on the surface.[53] to map the lunar surface and help to prepare 3D maps of it. Orbiter Chandrayaan-2 orbiter at integration facility The Chandrayaan-2 orbiter is orbiting the Moon on a polar orbit at an altitude of 100 km (62 mi).It carries eight scientific instruments; two of which are improved versions of those flown on Chandrayaan-1. The approximate launch mass was 2,379 kg (5,245 lb).The Orbiter High Resolution Camera (OHRC) conducted high-resolution observations of the landing site prior to separation of the lander from the orbiter. The Orbiter is still working fine and will use for Chandrayaan-3 operations.

Fingers crossed for a successful mission! After Beresheet, Chandrayaan-2, and iSpace's Hakuto-R, I don't think I can take a fourth consecutive failed landing.

Thank you scot, love from India🇮🇳🇮🇳

Good luck India.

Best of luck India! Hoping for a successful mission. Cheers from the US

I take so much pride in saying that my dad is in ISRO. I hope I give him the chance too, someday :)

who imagined, sixty years ago, that tens of thousands of satellites would be orbiting the earth?

All the best luck to the mission and thanks Scott for sharing!

Man you do your research extensively you not only covered the technical bits throughly but also the emotional value it holds for Indians.. thank you from India

There's this amazing comparison image with an old photo of someone from ISRO taking what looks like a tiny fairing and payload to test stand on the back of a bicycle...side by side with an 150ft LVM3 during liftoff. Watching the progress they and other space agencies have made over the past ~20 years is just incredible. Space exploration is built on audacity as much as engineering. Nothing is "impossible" and explosions are merely setbacks. It doesn't matter how many times you fail, only how many times you update the hardware and try again.

The "Moon Impact Probe" (MIP) onboard the CY-1 mission was *specifically designed to crash* and withstand the crash (It was in one piece after the programmed crash landing), demonstrating the capability to reach a specified location on the moon and providing valuable information and experience for planning future soft landings. On board this MIP, a component called CHACE conducted experiments providing in-situ data confirming the presence of water on the Moon, complimenting remote sensing data from M3 (NASA's equipment onboard the Chandrayaan-1) regarding the same. The next CY-2 mission had an Orbiter, A Lander and a Rover. The Orbiter continued to function optimally well beyond its planned lifespan while the Lander (Vikram) carrying the rover in it, crashed due to issues with its software, leading to an accumulation of errors resulting in a destabilised descent path. The Lander's ability to handle parameter variation or dispersion was minimal because ISRO scientists had not expected such margins for error, which ultimately led to the onboard computer trying to satisfy two contradictory requirements, resulting in the crash. This time ISRO has covered all bases and planned better for potential contingencies with the landing part. We are exited and cautiously positive about sticking this landing. Go ISRO.

Increasing tolerance in rotation limits would indicate they're trying to conserve RCS fuel

Just before the CY3 launch, ISRO chief had given few interviews where he mentioned in detail what exactly happened in CY2 lander failure and how this time they took measures to negate or minimize those scenarios.

Its awesome that India has joined the Artemis Accords opening up a lot more avenues and possiblity for cooperation and collaboration in space with India

Scott, love from India. Hopefully the mission goes successfully. Btw Chandrayaan 2 thing happened with me a few days ago in KSP

I'm actually happy to see criticism from some racist people on MY India's achievements, be it in space, defense, economy or any other field. It shows that we are growing. People who are really happy from our success won't be discouraging us by sighting examples from our societal problems, or pass religious slurs on us. Don't worry my fellow Indians, we are growing and we will continue to grow, though slow, but we will. The dogs can bark, they are just doing their job.

ISRO doesn't have a dedicated PR team. It's just 2 engineers/scientists managing the PR apart from their regular work commitments

Appreciate this video man!! you are doing an absolute great work out there.

Scott, I am from India and a regular visitor of your channel. Excellent Analysis. Hope this time the landing is successful. Also we will be launching Aditya-L1 solar observatory to observe the solar atmosphere from Lagrange L1 point. Then in early next year, NISAR, most expensive weather satellite made in collaboration with NASA will be launched. After that first human spaceflight. Existing time ahead. As you can see, we are investing in science for better future.

Thank you for the video. I was thinking that it has been more than 24 hrs and may be Scott's video is not coming. just imagine my surprise when I saw this.

Such a well made educational video. Thanks for covering Chandrayaan -3 mission Scott. 🙏

as an Indian it's very nice to see so many supportive messages for us Indians from all around the globe here , thanks guys Jai Hind Jai Bharat Bharat Mata ki Jai 🇮🇳🇮🇳 Jai Shree Ram 🕉️ 🙏🙏🙏🙏🙏

I was eagerly waiting for Scott's video on Chandrayaan 3. Finally it's here! ♥

Heckuva big rocket you got there, India. Good luck on the mission! Landing on the moon is not easy- it's as hard as rocket science...

The lessons learned and solutions implemented feel so Kerbal. I love it! The initial failure followed up with an iteration. So awesome!

Good Luck India and very well presented and explanation by Scott. Brilliant!

India would become the first that will land on South pole of the moon so every other space agency is actually curious what Data will be collected by this.

Chandrayaan 2 lander hard landed because of software glitch. It has to landed in specific location but due to software reasons when it is getting out of that precise area, it couldn't land. So this time the area of landing is increased 2 *2 km.

Being an Indian seeing this video felling proud ❤🇮🇳 Love and respect from India ❤️🇮🇳❤️

To all those usual fools who are always questioning: Oh, India is a poor country, why are spending money on rockets? Oh, why this when Indians are starving? And so on.. Please note the answer and never ever ask this again. The cost of this mission is 75M$ and with India's population of 1500M (rounded), thats 5 cents per Indian. Chandrayaan 3 cost every Indian just 5 cents ( Around 4 Rs) Get it ?? Please upvote this, so that nobody ever asks these stupid questions again.

I was waiting for this video, keep covering events of this ISRO mission

Hey Scott, love your content. There's an excellent Bollywood movie that came out last year called Rocketry: The Nambi Effect. Its a real life story of an ISRO scientist accused of espionage and his redemption. The start of the movie goes into great detail of ISROs roots and the development of the Vikas engine. Its a great watch and one of my favourite Bollywood movies

Thank you for this episode, Scott as also for your good wishes 🙏

INDIA HAS DONE IT

Installation of the igniter while sitting on a bomb of 138 tones is very pleasant.

I really love the comments congratulating us. Thanks to all of you from India ❣

What I love about Scott's channel than the EverydayAstronaut is he always makes a video ISRO's important events like this one. Thanks Scott.

The way video is made really awesome. Thanks. Feel proud for not only India but for all those who are helping mission to be successful. This learning will definitely help future endeavours in space.
