India's Flagship Lunar Mission Chandrayaan 3: Will it Brake or Break?

ISRO launched Chandrayaan 3 on its mission to the moon, with the Vikram lander gaining many upgrades over the previous flight, hoping to safely descend all the way to the lunar surface and soft land, a challenge which has seen 3 failures in recent years.

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.

[@firetree2007]

the reason is the whole basic design of the descending engine Chandrayaan is totally wrong, there is no successful module of this kind design, ie, instead of as all USSR, US Apollo and China's Chang'er, all used one single central big engine, Chandrayaan used multiple small engines with very rough control. For Chandrayaan 3, they did not learn the lesson from Chandrayaan 2, still use the same failed design, therefore the high probability is it will fail again.

[@rgaming161]

Chandrayaan 2 is not properly failed mission yes lander crash into the moon but moon orbiter is still working to the moon orbit Today

[@hieverybody4246]

What I read was there was a software glitch that caused the lander to provide very slightly too much thrust the entire descent, so that when it got close to landing, it was well before the landing zone. The software's goal was to land in a pretty small area, but since it was well outside that area, it was faced with an impossible goal and reacted erratically. Part of the correction is to make the allowed landing area much larger, just in case the initial glitch happens again.

[@vasukhurana-pb9ki]

another possibility is fuel shortage after it has increased its thrust more than required due to limitation (20% change directly in thrust which I heard) for reaching its small projected area for which it may increase its speed.

And as per there plans if they’ll be able to enter into space exploration and make profits it wouldn’t only uplift India’s status around the world but will create various opportunities for everyone. Just like they’re doing by collaborating with private and newer space companies. And talking about poverty within past 15 years India has lifted over 400m people out of poverty as per IMF. Thats more than population of US nd UK combined. It’s easy to say but bringing prosperity in a nation with such a culture play, lack of education, so many religion and a democracy. You can’t wish to change a national with so many complications to happen in a night.

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.

[@SeanONilbud]

Yes it crashed.

[@1999NIRUPAM]

@@SeanONilbudyou can’t simplify it by just saying it crashed. You need to identify what went wrong exactly to rectify it for your second attempt. Which is what was done and for this lander they reduced the number of thrusters and calibrated the software to new parameters which is where the primary error in the mission occurred as Mr.Somanath has mentioned

[@Ergzay]

Except that explanation is garbage because it uses a bunch of incorrect statements. For example, there is no "turning" going on. So the explanation about "very fast turns" is just silly. It's clear that the person talking doesn't know what they're talking about. Also the statement about error accumulation also makes no sense (or implies a very poor design) as it implies some kind of open-loop guidance to the surface, which can't work. If they're still doing the same thing then it will fail again.

[@albertovieira4844]

But all this would be discovered with the simulations. I don't understand how these flaws weren't evident. Several probes were sent for software calibration. And to say that they didn't know about the thrust of the rockets... I don't know, that seems very strange to me. It's too basic a mistake to believe...

If you don’t reduce your throttle at that point you start ascending. If you still have SAS in retrograde, as soon as you start ascending you flip. I call this cranial rectal inversion syndrome (CRIS) since I would have previously switched off retrograde if I didn’t have my head up my butt. It sounds like something similar happened to India’s probe. Just speculating here, but maybe part of the software was accelerating to extend the landing footprint while part of it was maintaining retrograde orientation. As soon as velocity went positive, retrograde flipped the vehicle. That would probably be enough to lock up the software. It is usually enough to lock me up. Like I said, CRIS.

[@Rudra-991]

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 :)

Congrats ISRO for such an incredible program

[@happy13singh93]

👉 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.

We KNOW russia is in the bad here trust me, most Indians oppose the war but russia also has us in a chokehold because of our historical relations with the USSR when the US was not exactly a friend of ours. We risk out loosing a lot more than to gain if we side with Ukraine. Indian policy has always been very autonomous and that doesn't gurantee friends easily, especially if you loose some old ones. We're trying to cut Russian dependence which is primarily in the defense sector by asking western nations to work with us and increasing spending in the local industrial complex by ten folds. TLDR; it is not a black and white stance to take.

And for the record, Ukr invasion would have stopped early on (or may have never happened) had it not been US/EU instigation to idiotic UKR premier to fight as their proxy. And you morons still see it as India's attitude of not taking your side when all you have been doing is trying to push RuS-UKR to fight till death so that Rus is either eliminated or weakend completely. What a coward you are who is too afraid to even call spades as spades.

[@GalileoAV]

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.

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.

[@AryanRaj-ib5oi]

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.

[@samgal9205]

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.

[@IMBlakeley]

Also it is not as if the majority of the money spent disappears, it is employing people to do stuff, they then spend that money in their communities buying stuff and the economy goes around. Meanwhile the data India will share with the other nations will have a quid pro quo in them also receiving data.

[@abi3751]

Atlast someone explained it in detail, even if it cost much its not a big thing it's for the development

[@adarsh-singh-bisen]

Intentions were good but logic was dumb. Chandrayaan 3 is the need of our country. In India people starving for food have different reasons. Some people who may get food easily in their native places migrate to cities for better education, health care, jobs and etc. Unfortunately, due to the high cost of living in these cities, people can't afford to live a lavish life so they choose to live on a bare minimum. Also, many won't highlight this issue but illegal immigration in India is also a reason for the rise in poverty. People belonging to a rural area will return to their village if they can't manage to live in the city, but these illegal immigrants have no place to go so they have to either live on the streets or develop a slum. When these slums get bigger, common people join them too. During Covid 19, many migrant workers were returning to their villages as they knew for sure that they will get food and shelter there.
