- Congratulations to ISRO for successfully soft landing on the moon with the Vikram lander from the Chandrayaan 3 mission - and over the last few days I've been hoping to get enough cool photos and footage to make a feature video, but as of right now I have a limited amount of stuff to work with, so bear with me as I dig into what we can learn from the images we've seen.

Congratulations India, welcome to the Lunar Community! As an American, i wish you many more successful visits.
Hereafter let's do it jointly 🙂
@arunpatil5302 Indeed. Among the stars, we are all brothers and sisters from the same mother Earth.
I don't care if it's Russia, India, Israel, China, or the US, a successful scientific mission to the moon is success for all humanity. In the words of Neil Armstrong, "That's one small step for man, one giant leap for all Mankind".
@@SpecialEDyunfortunately authoritarian govts don't think that way hence democracies should come together to cope with any problem.
@niladribanerjee2821 True, but authoritarianism falls to democracy when the people demand it, and that happens by showing them freedom, kindness, and wealth.
India has better quotes than the USA for this. "Be the change that you wish to see in the world", or "if you wish to experience peace, provide peace for another". Ghandi and the Dhali Lama respectively, who both have offered a wealth of wisdom on this subject.
For us, two of JFK's speeches are excellent reads if you haven't read them before. "We choose to go to the Moon", obviously since we are speaking of India's success. Why did India visit the moon this week, the same reason as the USA did, and all countries chose to, "not because it is easy, but because it is hard.
And JFK has another famous speech about how we consider our allies and adversaries abroad, referred to as "Ask Not What Your Country Can Do For You". Some excerpts:
"To those old allies whose cultural and spiritual origins we share, we pledge the loyalty of faithful friends. United, there is little we cannot do in a host of cooperative ventures. Divided, there is little we can do - for we dare not meet a powerful challenge at odds and split asunder.
To those new States whom we welcome to the ranks of the free, we pledge our word that one form of colonial control shall not have passed away merely to be replaced by a far more iron tyranny. We shall not always expect to find them supporting our view. But we shall always hope to find them strongly supporting their own freedom - and to remember that, in the past, those who foolishly sought power by riding the back of the tiger ended up inside.
...
And so, my fellow Americans: ask not what your country can do for you - ask what you can do for your country.
My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man."
@@niladribanerjee2821 But the truth is that it's America refuse the coop with China.
I work for a financial firm on a team with some members over in India. They were late for our meeting because they were all watching the landing. It was awesome hearing just how excited and proud they were.
There were big screensvin my office, everyone was watching I will never forget those moment. We very thrilled excited scared and finally super happy .
They did so much with such a small budget that we all should watch and learn from ISRO. Well done, guys and gals!
They can do because of various reasons ..
It's not something special bro as in India it is common ..
The sad part is they are paid 1/5 of what NASA pays for its scientists yet they work with lot of national pride.

no mention of the Indian tax payers who funded it? 😂
Well done India! I liked the way the lander did two distinct pauses during the descent. It gave the impression that it was in no hurry to get to the surface, rather they gave the sensors and software plenty of time to get the best data and best solution.
You got it right mate. They made just the correct corrections in the algorithms and put the ability to hover and decide go or no go for a particular site. If it's no go then r lander moves sideways a little then checks again if that place is a go or no go fir landing. If it's gets confirmed fully then only it will land there. It's marvelous peace of engering and science achieved here
Yea the HOVERING phases
too bad it was faked
Well done ISRO, good to see another rover on another world
I’m surprised that nobody has named a rover K-9 yet.
@@justinweatherford8129 It will happen someday, I'm sure 😆(bonus points if it is a quadrupedal walker like a robot dog)
@@justinweatherford8129 I'm not surprised. "K-9" as a term has pretty long history and established status as a name for military or law enforcement dog units. There's nothing like that linking it to anything space related. Using that name would essentially be shoehorning it in instead of using it organically and with valid reasoning.
Toilets
@@anteshellK-9 is a play on "canine". Rover is a stereotypical dog name. Just about every acronym in space exploration and generally astronomy is shoehorned for some kind of joke such as this.
What a feat. Congratulations to the entire ISRO team for their "don't accept defeat" attitude. They are all pride of the nation
This involves complex maneuvers, they navigated lander to South pole, very impressive!
They did this before during Chandrayaan 2 but only they missed the landing ..
And yes Spaceflight is always complex so there is nothing new ..
@@nirbhayatiwari5425they missed because of their over ambitions. If ISRO had increased the landing site from 500x500 meter to 2km x 1 km it was about to land safely.
@RajaRamMohanKaay 😂😂 now you are more qualified than those scientists
@@Gaurav90065 Depends on the situation ...

Rise and shine, India! ❤
Greetings from Argentina.
Congrats to India, I am so happy that they landed safely! And prove that they have a world (and moon:) class space program. We all look forward to their future amazing accomplishments!
The level of cofidence displayed by ISRO is astounding....the timing of the landing and the live video of the actual landing was shared with the whole world...! The whole thing boosted the confidence level of every Indian, wherever he or she may be.
They had reason to be confident: they put in the work.
Absolutely!
The dancing videos is from the g20 space economy leader's meeting held in Bengaluru this year. I was there, it was amazing 😂
They moved chairs out to make space for the unexpectedly enthusiastic scientists 🔥
That sounds like a great time. What were they dancing to?

What precise landing, the solar panels faces towards the sun. Wow.
Er. It turned around to face the sun after the landing.
@@TheGreatAtario not really, First when it landed sun was in left side same direction of rover's solar panel you can see in that video, but rover moves very slow so by the time it reaches few distance sun moved to top right side so rover turned
@@ElonHuskyThe rover will do the needful.
As an Indian, I want to say one thing
The Lunar day is 14 Earth days and night is 14 earth days.
At south pole, during the Lunar night, temperatures can go as low as - 300 deg Celsius, and the instruments (expecially batteries) will not come to life after that. Hence the project has a limited life time.
Now, having said that, I think the Solar Panels are on all sides if the Lander, because during the course of Lunar Day (14 earth days), the Sun will rise from one side, and set towards the opposite side. Hence I believe, to sustain a Lunar day, the Solar Panels should be on all sides of the Lander.
The rover, on the other hand, can change its direction to gain solar energy.
Hi rover travelled 500meter and 2 day before night they shut down rover for lunar night hope it can work again
Considering this is their first landing, they have deployed and utilised such a fantastic array of technology! Delighted for India
Way to go India😊 it showed everybody that India could do it for way less amazing🏁
Seeing the Moon dust blown by the aselenizing jets at the end of the video feels unreal. CH3 lander has radar altimeters but just thinking about how it could visually estimate range/orientation on such a fractal landscape makes my head spin! Well done ISRO ! You are the best!
Good work, India!! I hadn't even heard of this until I saw it had landed. Of course, I don't watch network news or anything like CNN, MSNBC, or Fox, so It's no wonder I had no idea this was happening.
It's good that you don't watch them, their views towards India are usually very biased and misleading for Western audience anyways.
good things ,keep away from the alphabet boys' propaganda
it's good never watch those news channels
Yeah there is some coverage by CNN but FOX is busy decoding the mugshot
CNN MSNBC busy discrediting India how poor it is . They don't know anything about Science .
Congrats to India and ISRO!
I would like to Congratulate India for their massive contributions to the rest of the World. 🚀🌚👩🚀
Not the first lol
@@vandanasingh6248first in south pole lol
That landing really looked on point. Almost unreal. Until you remember the gravity of the moon is not the same bastard to deal with as the gravity of Earth.
To be fair, its still the same beast, only the rates of change are different, the same control challenges remain. An excellent achievment.
No air too to decrease the velocity.
@@Meghnaaad No gust to wind to screw you over and adjust for.
You said it.. Unreal.
Have a look at ch-3 honeycombe like lander pads to obsorb shock while landing
The Rover being able to come out so soon after landing points to another achievement. That the landing was much smoother than expected .. so much that it did not rile up the dust clouds on the surface during landing. Very few & rare dust clouds meant very little time for their dispersement (would take a long time to settle down on surface due to low gravity.. dispersement would be less time consuming if volume of clouds is less) .. & quickening up the further procedures. That is a smooth sophisticated achievement. Wonderfully done by ISRO
Dust doesn't form clouds on the moon. Never has, never will.
@@TheEvilmooseofdoom I'm talking about dust clouds formed by riling up the sand on the surface as the lander came in contact with the surface with an impact. Would take long time to settle down due to lack of gravity .. But would disperse quickly if only very little of it is formed .. this ensuring quick river exposure without risking it getting covered with a dusty layer of surface dust.
There is very little gravity on the moon, so you have to use thrusters to fire very delicately, trying not to get bounced up again. The first location to land was not acceptable, so it had to retarget to a second location. There was only enough fuel to re-target once, so luckily it all worked.
It's like taking a Helicopter flying at 6000 KMPH to land on moon surface where there is no atmosphere & with rockets/thrusters. Now one can imaging the complexity & what has been achieved.
@@arunpatil5302True at a 70 million dollars this is mind bogglingly amazing and cost efficient, especially considering ISRO doesn't even have the ability to recover back the rockets. If you guys can master the capability to land back the rockets, these missions would get even more cheaper.
As long as you scale everything for 1/6th gravity, including the TWR, it's not a _huge_ issue. Still some places you can't land, but the bouncing issue really isn't that severe
@@Tate525ISRO is currently working on NGLV which is basically a reusable rocket having a payload capacity of around 25,000 Kg. I think it's engine is ready and it will be used to launch satellites around 2028-2030 the same time when India planned their own space station and mangayan 2( Consists of Orbitor and lander to Mars)
Well done, India. Congratulations! ❤
0:00 - 2:00 NOW THIS HOW YOU 'STICK' A LANDING ! ! ! WELL DONE I.S.R.O. ! ! !👍👍👍👍👍👍👍
The mission is not to take selfies but check regolith for constituents, temperature gradient & few other studies. Due to limited features, payload, power, communication baud rates etc camera has low resolution but enough for its intended purpose.
We are really very proud of our ISRO scientist. 🇮🇳 I'm so happy reading all the comments here . Such an educated bunch of people with no judgement or racist remarks. You all are the best . And thank you Scott for such a wonderful video 👍🙏
Congratulations India. Great work!
The temperature jumps between -10 and 50 degrees C just within 8 cm of pits and bumps !😲 This info is quite intriguing.
I just wonder why they used a superscript zero (0) instead of a degree sign (°) on the chart? 🤔
Well done, ISRO! Congratulations on a successful landing. Look forward to seeing more images!
That was a very smooth touchdown! Well done ISRO!!
And, you already have some science data returned with the temperature gradient below the surface of the regolith!
Thank you!
I'm excited to start calling all of my landers in KSP "hard landers" from now on
Keep practicing lithobraking your hard landers.
I just reclassify them as "impactors".
I'd call them ISBMs - Inter-Space ballistic missle.😂
Bunker busters to keep the alien invaders heads down. Never seen a UFO in KSP, but never seen one IRL either. Still, better safe tha sorry!🤣
Water on moon was first discovered by Chandrayaan 1, and later confirmed via NASA.
@@hundredfireifyTechnically it was a Taiwanese chip. No competition here was collaborative success.
@@hundredfireifyNot really. It was ISRO's impact probe that picked up the evidence for water physically from the lunar dust with spectroscopy. NASA's payload was on the orbiter and only added to the finding with remote sensing data much later. NASA tried to take the credit with questioning the veracity of the probes findings, but all doubts where cleared and even journals have revised to credit ISRO for it.
@@hundredfireify supposedly u buy iron from Russia build tanks in USA......would u give credit to Russia
@@paragbhuyan6090 the whataboutists really cant give it a rest
@@hundredfireify physically most of the scientists in nasa are indians...credit return back to us also
It is a wonderful accomplishment! If I'm correct, the lander is roughly at the equivalent of Utqiagvik (also known as Barrow) in Alaska, the northernmost point of the US, which is in line with the northernmost point in Norway, and well above Iceland. Flipping to the south pole, McMurdo is closer to the pole, but it is within the boundaries of Antarctica for a good chunk of the latitude (although a few of the large bays cut in). So respectably close to a polar landing. Certainly, as you say, the polariest so far.
Kudos to ISRO. For the budget they got for the mission, this is an unmatched achievement
Not expecting high quality images from ISRO, as with only 14 days they would prioritize science than clicking high-res images and sending back.
Rover only has 1 megapixel cameras just to guide rover not to take footage
Á
But the Orbitor of Chandrayan 2 has the power
Mission accomplished by ISRO❤
Wow, I am really surprised by the temperature data. If the thermal conductivity goes up (as deeper probably means denser) if we drill a few meters deep, that temperature difference could be used as an energy source! Like the Stirling engine or something similar.
Yup, as soon as I parsed the graph to "+60 C to -10 C over ~10cm" I was thinking "surely this can be used to generate power, if only for low-power cheap sensors 'scattered' over the Moon?".
I assume, this will not work well.... As the regolith does not transport heat well, this means that temperatures can be very different in two spots that are near. But this means two things:
1) as we have seen, temperature can be much lower just a few millimeters away
2) If you buid an engine that harvests energy from temperature difference, it will quickly heat up the surrounding of the cold end of the system. And due to the bad heat transmission of the surrounding, it will stay that way, and the engine will stop working...
@@Rainer_Landes 100% right, but maybe if we dig deeper there will be higher thermal conductivity
@@dmitrynuzhdin this would be perfect, then!
@@dmitrynuzhdin
It may also be possible to inject water into the drill hole and greatly expand the surface area and conductivity of the cold sink.
Congrats to ISRO and thanks, Scott, for this excellent and informative video.
Thanks for the update Scott! Very informative and enjoyable as always. The general software problems you mentioned has, is, and will continue to have the highest risk of failure in any and all complex systems (aside from non mature or experimental tech), as I'm sure you know. The nature of and problems of software quality control would make a great topic to present! Cheers!
AI should be used to change the code based on real time sensory data and that updated code can be programmed into the onboard hardware realtime. Not sure if that has been done on CH3.
@@striker44 @striker44 That's a great idea! But let's be realistic, there's many complex issues to solve in programming first, meaning AI is about as ready to take over programming as it is driving cars (probably less so).
For example, large complex systems have many many possible states, based on the variation of the combined states of all of the smaller modules that comprise the total system. In other words software gets complex quickly, in part due to the combined possible states, substates and state transitions of all system subcomponents.
It's not like a chess game where every move results in a state with a finite set of possibilities, based on a fixed rule set and a fixed range of potential input values (squares that each piece on the board are able to move to at any one point in time).
And before you even talk about coding errors, such as priority inversion (Mars Pathfinder is a splendid example), there is the basics of generating system requirements by humans, and then mapping those requirements to actual software.
AI is helping but programmers aren't in any danger of becoming obsolete any time soon! Cheers! (and sorry, I didn't mean to write a book here)
@@striker44 that will be a disaster there is no time for testing when landing on moon but they can simulate the scenarios on earth
6:29 - " Speaking of impact probes, Luna-25 .....".. subtle, Scott..😂

After commenting on the excitement/interest shown for the launch, I'm surprised you didn't mention that it broke the TH-cam livestream concurrent viewer record.
India named the place and its surrounding where lander landed as ShivaShakthi.
Thanks Scott,
Very informative video. Looking forward to the exciting science coming out of this mission. Well done ISRO, truly inspiring.
Thank you Scott for explaining what the mission is and how it's done..
Im so happy to see this mission succesful
Google earth having the moon mapped just blew my mind, thanks
its been there for more than a decade lol
Wait till they hear about Mars...!
Its Google Moon actually
There's something immaturely amusing about a penetrating probe being called ChaSTE.
By comparing the shadows, you tried to figure the time it has taken between two incidences. Loved it. Felt like watching a thriller movie.
Our prime minister said, Chandrayaan 3 success belongs to the whole world; all of humanity. I would like to congratulate people from all around the world, scientific achievements from this mission will help all of us for future space exploration.
World Best Sky Scientists are in INDIA ISRO🙏🏻
And also NASA 😊
Super thrilled for India!
I'd be curious to see at what depth the temperature remains constant, if it does. A full lunar hour by hour plot of temperatures would be nice
A 70°C fall in temperature with just 10cm depth during the day time on the moon, is honestly very scary. We really do take our atmosphere here on earth for granted.😂

@@Xinnie_The_FluWe wouldn't be alive if it was that extreme.
@@doctorpanigrahi9975 yep
@@Xinnie_The_Flu It seems like it's more extreme than hot dry sand on the beach, but maybe only by a factor of 2. Maybe more close if the sand was black?

This got me thinking "Oh you could probably automate that with a script of some sort". Which made me remember Scott is a programming wizard who works for Apple. So... in a way it's nice to know even the super pros have those tasks that sound simple but end up being a pain in the ass to automate.
Congrats to ISRO and great break-down Scott!
Great achievement by ISRO. Looking forward to some good pictures from the surface.
You missed the info about the propulsion module. Propulsion module of Chandrayan 3 has been equipped with spectrometer to observe Earth after it has deployed the lander and use the readings to correlate it with the observations of exoplanets to determine which exoplanets emit similar spectral signatures like Earth aka in Habitable zone. Such efficient use of technology, nothing goes to waste. Good work India!
Scott I very much enjoy watching your videos, you have my gratitude for your effort. Could you explore the type of hardware on this probe in one of your next videos please? I want to learn about the types of rockets, thrust and how they turn the probe around to orient it to land. It seems that many missions have failed in this endeavor and I am not sure I understand the true nature of how difficult this task is to get just right to reach the surface of the moon intact. Many thanks to ISRO for getting this done perfectly.
Hi Scott! Love the videos! I hope the flying is going well! Fly safe!
"...they corrected the problems and tested all the potential things that could happen. In the end the landing was actually flawless and all that extra work wasn't necessary". Funny, that sounds eerily like the comments made after Y2K, when everything went flawlessly and the eyes of untold thousands of software stiffs round the world bugged out when the millions of man-hours they'd been putting in to make sure of it were casually dismissed as unnecessary. Some of us cried ourselves to sleep for a month after that.
Well done, ISRO, and especially your painstaking and meticulous software teams. The lion's share of the glory is yours.
And thanks, Scott. This is the best video and best commentary I've seen on this so far.
Nice temp graph. I can appreciate more now how water can survive just below the surface.
Way to go - ISRO! Great analysis Scott, as usual.
8:26 Wow. If u could dig your finger in the soil near Lunar south pole then the tip of your finger would freeze while the base of it would be at a barable hot temperature. (Yes, we need a thermally conductive pressurized glove to experience this)
Congrats to India! 😊

Stay safe there with your family! 🖖😊
Isro says.....
'Besides Sulphur, Preliminary analyses, graphically represented, have unveiled the presence of Aluminum (Al), Sulphur (S), Calcium (Ca), Iron (Fe), Chromium (Cr), and Titanium (Ti) on the lunar surface. Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O). Thorough investigation regarding the presence of Hydrogen is underway.'
Well so far that sounds very much like what apollo found. I would expect some uniformity in the regolith though.
I was expecting "speaking of impact probes.... chandryan 2" but glad that was not the words that followed. Congratulations abound for India!
After Mission moon its time for Mission Sun in about 5 days from now, race to the moon's south pole has been won by India, but there is a lot more to come in the Space Race 2.0 🇺🇸🇷🇺🇨🇳🇮🇳
Race? No offense but China and US are still decade ahead of India in Space technology
But the first to find water. How do you measure 110 years ahead? And some say it is for humanity and who knows. Some things may be shared.
ISRO had repetitively mentioned it doesn't believe in a race and we are not trying to do one up against any nation. Space race back in the days happened due to US and USSR cold war.
So, ISRO goes with it's own pace and plans. Doesn't care which country reached where.
@@amitpatilamit Maybe it's not literally a race to ISRO and India, but it does mean something beyond the science. Otherwise, it'd be interesting to know why ISRO and other Indian authorities have said so, and what scientific purpose "branding" the Moon with logos on the tires serves (not suggesting anything sinister, but there is some national pride involved, I'd wager).
@@MARIAS_ALAHTANOKAnd all the more better that India won this.

I was waiting for a video like this!
Thanks for an awesome overview of what's happened so far with this moon-landing.
I'd read that in spite of having an X-band antenna on the lander, ISRO faces communications bottlenecks in getting images transmitted back to Earth and processed for release. I wonder if that will be addressed for future missions?
I think the Rover has 1 mega pixel camera and the data rate between the Lander and rover is 600+Kpbs or something like that. Hence it would be better to use that that rate for the science that the shitty 1 MP camera images..
@@HemanthKumarJadhavmegapixels is almost a meaningless measurement. Pixel size, Field of view, dynamic range, and other things matter so much more.
@@-DMI think he means to say that if the area your camera will cover is limited as well as close you do not need a camera with high megapixel....because you will not have to zoom in much digitally to study the area in detail...perfect logic...
Well done to our cousins in India - we in the west salute you!
Great update Scott.
When you realise rover only has 1 megapixel cameras..so it is only meant to guide rover not to take footage. Thing is that ISRO is not very much in PR they do it according to their needs to carry out experiments. Even though mars orbiter had great cameras it took great images but not as much as we expected even if took ISRO never released them. Same with chandrayaan two despite having the most powerful cameras orbeting moon they never released many images. ISRO need a dedicated team for PR
Secrecy
@@sivag2032which is a shame, NASA releases everything
The issue is the data rate is very slow. This time we got live images because there is not orbiter only lander so got more space for other stuff.

Great video, Scott...👍
That's a pretty steep temp curve over a short distance, but it would show that in the 'polar' regions, water ice in the regolith would be practically just subsurface. Antarctica exhibits the same properties under the ice... At Beardmore South Camp, about 1 meter down (and the same below that), the average temperature of the ice is -40 (C/F)... which is the average annual average ambient temperature there...
On the moon just 8 cm down it's -10°C 😮
@@Ayush-vy2kq I know... I saw ... but unlike the Ice, it has no atmosphere, which makes ALL of the difference in my statement...
@@gregalbert4033exactly! Atmosphere works like a lid. I expected a good temperature difference on lunar surface. However difference this big within 8cm is interesting. This can help understand properties and composition of regolith as well. Also, this would mean we may not have to go deeper to get water ice in case if there is any decent amount down there. Exciting times to learn new things about Moon! Next few years are going to be awesome!
Given it’s 2 week service life I suppose uploading HD images and vid would take up valuable computer time. So in budgeting time for upload images may be tertiary. Concentrate on its science.
It’d be grand if it wakes up next month. Even if only the lander resumes.
And no comment on its very low cost. That alone is an achievement.
Apparently it cost less than a typical big budget film. Well done India.
A note on "software problems"... If Apollo 11 was automated with a system which followed the protocols perfectly, it would have crashed. It too had an unexpected problems which the "code base" didn't handle properly.
This stuff is legit hard. And I was happy to hear ISRO folks saying Chandraan 3 was "designed for failures", even though it does sound bit odd if you don't know the context
The prime problem was not code base, but data overflow. The computer was to slow.
@@TheEvilmooseofdoom The radar data overflow wasn't anticipated, so there were no protocols for dealing with it. That's the metaphorical "code base" problem I was referring to ;)
Congratulations to our fellow Indians friends 🎉
If we ever mine for water on the lunar south pole, it will almost certainly be a limited resource, and some of it will be vaporized just by disturbing the soil, so we better have a good plan for using it as efficiently as possible
Maybe we'll have to develop infrastructure that can survive the lunar polar night to actually harvest that water
Congratulations India and ISRO!🎉

I am really happy to see our science enthusiastic friends across the globe, especially from US, congratulating for this intense mission. I believe Chandrayaan-3 will help humans in understanding more about the lunar surface, environment and the chances of surviving there. Thanks.
Was waiting for this video
Thanks for the excellent analysis.
Scott I've heard that the ISRO sun mission is just a couple of days away, could you please make a video on that? It would be great if you could explain what Lagrange Point L1 is. Thanks for the great content.
If you only want scott to explain, that's fine too, but i am gonna say it anyway. L points are those points in space were the gravity between planets and the sun is such that a thing at those points can remain suspended there with minimal or no fuel. There r 5 l points when talking earth and sun. 4 and 5 are stable, and pther 3 are unstable. Means in 1,2,3, and some fuel is needed to keep your craft there. Aditya L1 is going to the L1 point (obviously) because this is a point that provides the clearest view of the sun.
It's simple bro :-
L1 is located 1.5 million kilometres directly 'towards' the Sun ...
L2 is located 1.5 million kilometres 'away' from the Sun ...
@@nirbhayatiwari5425"It's simple bro", can't get more condescending and un-informative than that.
It's on sept 2 aadhithya 1, Aadhithya - Sun.
the solutions to the restricted three-body problem, are called Lagrange points. Any two massive and gravitationally significant objects would have 5 Lagrange points (3 in-line with objects, 2 at an angle of 60 deg), some of them will be "meta-unstable" points (like L1, L2, L3) which can be considered as a hill and it would very difficult to reach on top of those hills in the gravitational field. Considerable amount of fuel would always be needed to achieve that point as well as to stay around that point for a period of time. SOHO, JWST, WMAP, Gaia, etc, were forced to orbit these Lagrange points to make observations but with constantly using fuel to stay close to these points. Similarly, Aditya 1 will be designed in the similar way. Other Lagrange points, called "meta-stable" points (L4, L5), around 60 deg to earth-sun, are considered as a valley in the gravitational field, where its easy to place an object but very difficult to take it out. These are often termed as Parking Spots in space because they are like gravitational wells which often attracts space debris, dust, rocks, or asteroids which may remain trapped there for years. Earth currently has 3 asteroids, called Trojans (near earth objects), trapped in L4 and L5... which are the expected to remain there for a couple of thousands of years.
When the satellites run out of fuel, they simply drift away from Lagrange points (L1, L2, L3) and start orbiting the sun. Satellite missions are often planned using "meta-unstable" lagrange points because of their short service time and planned disposal after decommissioning, i hope you understand why scientists dont want satellite trash to compile in the "meta-stable" point, because of obvious reasons, these areas must remain clear for future plans. Proposed plans include space stations/colonies or relay centers, which will be parked in the "meta-stable" points to keep them in the exact spot in space, for years.
ISRO Chief dance is old footage from some other function. Nothing to do with recent launch. Twitter users just used it as a meme.
as always, you're very good!
Thanks for the video!
ISRO just released the photos from rover camera ✌️spectacular
