- wiseowise 3y ago> Some may argue that such endeavors push technological boundaries, inspire global scientific collaboration, and prepare humanity for existential threats. It is widely known, not “some may argue”. > However, considering the vast resources assigned for a mission with no direct immediate benefits to Earth's current problems, one could argue that our focus should be redirected towards addressing environmental crises, poverty, and global health challenges on Earth first What makes you think we can’t tackle both?
- deleted 3y ago[deleted]
- bofadeez 3y agoWhile I appreciate your engagement with the topic, I must point out that the notion that we can 'tackle both' is a dangerously simplistic perspective. The resources—both financial and intellectual—that are poured into space exploration are not infinite and come at the expense of urgent, life-saving initiatives here on Earth. To say it's 'widely known' only underscores the normalization of this skewed prioritization. We're not living in a utopia where all problems can be solved simultaneously; we're in a world where choices have consequences. The urgency of our Earth-bound crises doesn't afford us the luxury of romanticizing space exploration as if it's without trade-offs.
- Symbiote 3y agoIf you're looking for wasteful effort to direct elsewhere, I suggest reducing the money spent on social media, advertising, sport, movies and so on before space exploration.
- password54321 3y agoIt is almost like some fields try to drive off as many people as possible from lack of opportunity, to having extreme requirements and being driven by politics.
- deidei 3y agoCongrats to the team at ISRO! It makes me wonder, what is it that ISRO does differently than most other government agencies in India that makes them so efficient.

- srivmutk 3y agoMomentous day not just for India, but also for humanity.
- darthrupert 3y agoWell done to everyone involved!
- taveras 3y agoThis is incredible! Congratulations to everyone involved
- rhuru 3y agoThis is a big achievement for India. Not just in space exploration point of view but the side effects of such projects are more interesting. Dozens of major private companies focused on making this success making various spare parts including steel cranes by Tata steel, special alloys of Mishra Dhatu Nigam (The Alloy Company), wings by L&T Aero etc. etc. I know some people here and they were so proud and focused on "excellence" which I think is often missing in what we Indians normally do. Space programs are important because of precision required. It created a discipline and desire for perfection not just for ISRO but for all their suppliers and vendors. Hope this habit spreads.

- soligern 3y agoThere are some very interesting, and arguably more challenging missions coming up including a Venus orbiter, manned space flight and a Martian lander. This should really help solidify the manufacturing space around this.

- steno132 3y agoAn embarrassing day for America. The country that first visited the Moon should have explored the lunar south pole decades ago. Then the dark side of the moon. Then a manned colony. Instead we are beaten by a foreign nation to the south pole. And our next project is a manned landing on the moon, which we already accomplished in the 1960s.
- poyu 3y agoDoesn't it just all comes down to money? The US just doesn't focus on that anymore. Which is a shame, I guess.
- kpandit 3y agoWe are doing now what you did half a century ago. How exactly is that embarrassing for you?
- steno132 3y agoThe US should have been to the first to the lunar south pole, not a foreign country.
- nrb 3y ago“Here men from the planet Earth first set foot upon the Moon July 1969, A.D. We came in peace for all mankind” To the moon, we’re all foreigners.
- steno132 3y agoHumans don't view things from a moon perspective, they view things from a human perspective. Space races are real, it's each country for itself, and it's a zero sum game. And today's not a good day.
- nrb 3y agoGreat to see other countries making accomplishments in space, I don’t see a cause for embarrassment when we’re driving rovers and helicopters around on Mars.
- mirchiseth 3y agoIt will be cool to send a buddy drone with these landers. A minute or so before the touch down, detach from lander and shoot the landing. Then go back and attach with lander for charging and do periodic flights.
- yumraj 3y agoDrone on Moon? How will it fly? There is no atmosphere. But yes, it’d be cool if it were possible.

- deleted 3y ago[deleted]
- viableSprocket1 3y agoI get this is tongue in cheek, and it's true that everyone's brown, but a couple of points of note: 1. ISRO has reserved spots for Scheduled Castes / Tribes (historically under-represented castes and tribes), which is far more explicit than having a DEI committee [1] 2. There are probably 10-15 primary languages spoken across the teams given regional differences in India. I would guess society is closer to EU than US in terms of homogeneity but that's pure speculation. No opinion on whether or not it helps anyone soft-land on the moon, though.

- kypro 3y agoIt was tongue in cheek, and you make a great point, the idea every Indian or every European is the same is absurd. That said, my comment was pointed more towards NASA and the West generally. I have been getting the sense that NASA don't like the demographic of their organisation very much lately which I think is sad given their accomplishments. Were this a video from a NASA control center I expect a lot of people would be commenting on the colour of people's skin and that's a shame. I have been rightly downvoted here for this. My comment was in poor taste, but I saw an opportunity to poke fun at the absurdity of the Western view of diversity. For whatever reason I've noticed we seem able to recognise the absurdity of the claims we make about diversity when it's not in a Western context. Eg, the idea that to be successful at anything you need people with different skin colours involved is clearly not true – and it's sad this idea is even being entertained by an organisation as well respected as NASA. They should care about hiring the best individuals the US has to offer. At least in my opinion.

- goku12 3y ago> The Moon has been on a role eating landers and space probes lately. The complexity of landing on the moon is somewhere between that of launching a spacecraft and that of a self-driving car. It's sad that so many landers were lost - it would have been heartbreaking for those who built them. But I hope that they attempt it again and perfect this complex task.

- the-dude 3y agoDoes anybody know if we will be watching a simulation or actual footage? I am asking because the livestream of the last failed moonlanding this year didn't feature a single second of footage. None.
- jvm___ 3y agoWhy won't the people landing on the moon cater to me?
- _visgean 3y agobut seriously why would they not? If they have something nice to show of why not? This is publicly paid project (by indian tax payers) that is political in its nature. Why not show as much as possible?
- fractalb 3y agoIt's simulation for sure. Would there be sunlight to view it live?
- ethbr1 3y agoYes. For solar panel purposes they're landing in the lunar day (14 Earth days?). Edit: At the start of a lunar day, which equals 28 Earth days. (Source: BBC https://www.bbc.com/news/live/world-asia-india-66576580 https://www.bbc.com/news/live/world-asia-india-66576580 )
- vivegi 3y agoThere's no footage from the last one as the lander crash-landed on the surface of the moon. NASA reported locating the Vikram Lander's debris in Dec 2019: https://www.nasa.gov/image-feature/goddard/2019/vikram-lander-found https://www.nasa.gov/image-feature/goddard/2019/vikram-lande...
- dotnet00 3y agoDefinitely no footage, at most maybe a picture if it lands successfully. The only footage we have of any spacecraft landing anywhere other than Earth is either from Apollo or the Perseverance skycrane deployment. If they do have footage, it'll be like the latter, retrieved after the fact.
- jvm___ 3y agoScott Manly has a video on why he thinks the last one failed. It sounds like their landing software didn't have "oh crap, we're way off course, just land wherever". It only had the happy path of "fly to here and land", so when it switched to the landing phase it tried valiently (including flying upside down) to try to fly back to the landing zone, but the landing zone was much further than fuel supplies allowed. Hopefully they have upgraded software to just gracefully attempt a landing, and hopefully they won't be off course.
- raverbashing 3y agoThis applies to general software development but is especially true in this case While we think "this cannot ever happen" in a lot of cases it can, in ways you did not consider. Both for good and bad
- oaktowner 3y agoWhile I worked at Google I once searched for "//this should never happen" in the code base. It was in there. A lot.
- gora_mohanty 3y agoThat might still be OK if that path literally should never happen in normal operation, but us used, e.g., to handle an error, or at least log it, if the impossible happens because the software is deployed in some unexpected configuration
- oaktowner 3y agoYes! Totally agreed.
- rob74 3y agoIn general software development it's usually not a problem if your program crashes, then you can fix the bug and run it again. If the thing that crashes is a lunar lander however, you should put a bit more effort into covering all the eventualities...

- wheelerof4te 3y agoWe get to see more images of the Moon's surface. In a previously unexplored region. How is that not a big deal?
- mmx4332 3y agoThis may not be a popular question, but given the amount of poverty in India, is a space program really the best expenditure? As a geek, I love the space program. As a human, I don't think it makes sense given the poverty.
- pietro72ohboy 3y agoA nation isn't a singular-minded entity; rather, it comprises diverse citizens who assume various roles and contribute uniquely to global improvement. Just because they've successfully landed a rover on the moon doesn't imply the abandonment of all efforts to alleviate poverty. Honestly, why does the recognition of India's positive accomplishments always seem overshadowed by the specter of poverty and other challenges? Did the Americans eradicate every societal issue before embarking on their lunar mission? Indians should be proud — this accomplishment is truly remarkable and signifies positive societal strides toward a better collective future. Such achievements ignite hope, and progress is fundamentally built upon hope, regardless of the symbolic origins it might stem from.
- dotnet00 3y agoAn alternative perspective to consider, what happens to all the skilled engineers interested in and capable of working on advanced technologies like those intended for space if a country decides to put all other development on hold to singlemindedly focus on eradicating poverty? What would happen to the next generations of talented potential engineers? What value would there be to pursuing an advanced education? Since obviously a space program isn't the only "luxury" that should be put on hold if poverty exists! The talent would all leave and the next generations would be less incentivized to pursue the very kinds of careers that help a country develop.

- the-dude 3y agoI saw the onboard camera show movement after the celebrations started. Did anyone else see this? The onboard has not been shown since.
- shivdeepak 3y agoThat's probably because the image data being larger than the on-board sensor data would take longer to reach earth, thus the latency.
- the-dude 3y agoObviously I am not a golfer, but I would have waited until the onboard stabilized, sensors be damned.
- goku12 3y agoThe sensor data is a reliable low-entropy indicator. The engines are probably cutoff based on the same data (most probably a set of load sensors on the legs). If the data indicates that the engine has cutoff, the craft is stationary and if the data is still streaming, then it's a pretty good indicator that it worked as expected. I would trust it more than the video - especially when the video is lagging heavily. PS: I have worked extensively on something related. Video is good to have and helps in post-flight analysis. However, it can also mislead sometimes. Sensor data gives you a much clearer initial picture.
- dirkc 3y agoThis happens a lot to me in KSP, the lander tends to slide all the way to the bottom of the slope. Most of the time it's okay, just need to tweak the dampeners on the landing legs a bit ;) EDIT: I went to re-watch the moment on youtube and it does seem like the lander moves slightly to the left!

- ceejayoz 3y agohttps://en.wikipedia.org/wiki/Lunar_south_pole https://en.wikipedia.org/wiki/Lunar_south_pole > It is of special interest to scientists because of the occurrence of water ice in permanently shadowed areas around it. The lunar south pole region features craters that are unique in that the near-constant sunlight does not reach their interior. Such craters are cold traps that contain a fossil record of hydrogen, water ice, and other volatiles dating from the early Solar System
- actuator 3y agoI believe Chandrayaan 1 has detected water, but not sure if it was the first one to do so
- abhayhegde 3y agoThe definitive discovery of Moon water came from Chandrayaan-1 which carried with it a NASA-provided science instrument called the Moon Mineralogical Mapper—M3 for short—that observed how the surface absorbed infrared light. Using this data, M3 determined that previously suspected water molecules were ice inside the Moon’s polar craters [0]. However, the first direct evidence of water vapor near the Moon was obtained by the Apollo 14 in 1971 [0]. A series of bursts of water vapor ions were observed by the instrument mass spectrometer at the lunar surface near the Apollo 14 landing site.

This is not the moment to go there, but still since we're on the topic, current leaders of Britain (Prime Minister), Ireland (Taoiseach) and Scotland (First Minister) are all of Indian-Subcontinent origin. Britain and Ireland have leaders of Indian origin, while Scotland has of Pakistani origin.

- alephnerd 3y agoSunak and Yousaf are both Punjabi, Sunak's family was from Gujranwala region in Pakistani Punjab before partition and Yousaf's is from Khanewal in Pakistani Punjab as well, plus both are the children of East African Indians who moved to the UK during the mass expulsion of South Asians in the 1960s and 70s (Freddie Mercury is also part of that community as well, though ethnically Parsi Gujarati). Also, they both attended elite Grammar Schools, so they were within the same Old Boys network. They're much closer culturally than Varadkar who's dad's side of the family is from Konkan region (the coastal region stretching from Goa to Mumbai/Bombay)
- Artistry121 3y agoInteresting how close politicians are with anything related to the moon. Nixon on TV as much as the astronauts in 69, Modi on TV here. Both during massive consolidations of power towards the leaders who also have major corruption scandals.
- the-dude 3y agoIf the lander flipped over and exploded, it seems nobody would have noticed.
- robofanatic 3y agoThat is exactly what happened last time during Chandrayaan 2. ISRO noticed and fixed the issue and launched Chandrayaan 3
- balozi 3y agoI don't know much about landing extraterrestrial missions, but I would imagine that the moment of touchdown is exactly the moment everyone in the control room should be keenly paying attention to their assignment instead of jumping up to celebrate (or at least try not to distract those that are). Because if that thing sunk into a pool of moon water or landed on top of another lunar lander, it would be 15 minutes before anyone realized. Just a minor layman observation. Anyhow congratulations to this team and to the people of this great nation.
- goku12 3y agoThey would have a loss of telemetry that screams of failure. I don't see the possibility that they wouldn't notice.

- zabana 3y agoI wonder what else India could potentially achieve if they could retain their top talent. Congrats !
- soligern 3y agoIt’s going to be very hard to brain drain a country of 1.4 billion people. That doesn’t even take into account the massive amount of money the diaspora sends back. The above is usually an argument people make when they don’t want to let immigrants into their country.
- codegeek 3y agoDon't think of Brain Drain as a lose lose situation. Lot of Indians who leave India contribute in many ways and in fact bring tons of knowledge and skills from the global world back to India (even if they don't live there physically). Not to mention that amount of money that is exchanged by Non Resident Indians (also known as NRIs). It is good that Indians are able to go aboard and bring a globalized knowledge back to India.
- anovikov 3y agoIt went so cleanly it almost made an impression of being easy. Congrats!
- underdeserver 3y agoThe applause for the successful landing starts at 44:50 (take a few seconds' buffer).
- robofanatic 3y agoGreat achievement! Space is incredibly hard as they say. Hope ISRO continues with this momentum and achieves more success in its future missions!
- nothrowaways 3y agoWhat would happen if they found water?

- hdesh 3y agoThey might take a quick shower first. It was a long journey.
- robofanatic 3y agothis joke would fly on reddit not here.
- blackoil 3y agoNestle will buy SpaceX!!
- robofanatic 3y agoThat would be icing on the cake, but the real success was to get there. It's a big step forward that'll help humanity, not just India.
- Symmetry 3y agoLanding on the Moon isn't easy and making it on the second try is pretty good, it took the USSR tons of tries to finally get a good soft landing. And recently we've seen groups from Russia, Japan, and Israel try to land softly on the moon without success.
- Eddygandr 3y agoPlease please let this bring on a second space race! I want humans on Mars during my lifetime!
- gautamsomani 3y agoYeah! Me too!
- mfrw 3y agoWhat makes this a "WoWW!", is not that this is the first time humans sent something to the moon, but when one factors in the budget relative to others. Although, I do not have reference for what the exact budget was/is.
- kpandit 3y agoI was trying to find the schedule for the rover including on ISRO's website[1], but the closest I could find was this[2] and this[3] that suggest the rover will be rolled out in the next few hours or may be tomorrow and it has a life expectancy of one lunar day(14 earth days). Anyone knows if it will be streamed as well?

- btbuildem 3y agoThe moment of landing: https://www.youtube.com/watch?v=dim8elzo5vE https://www.youtube.com/watch?v=dim8elzo5vE When I look at this, it seems it's a long-range optical feed of the moon surface with lander graphics laid over it. Has anyone found footage of the actual craft touching down? It would be amazing to see.
- kimbler 3y agoHopefully they can leave behind a camera to film the next arrivals.
- haolez 3y agoOn the dark side of the moon?
- btbuildem 3y agoNot sure if you're joking.. but there's light on the dark side of the Moon, it's just called that because it's never visible from Earth. I assumed the craft that brought the lander into orbit would have some sort of visual tracking, but maybe the distances involved make that impossible and all we get is telemetry + a rendering to visualize it.
- 14 3y agoI am hoping that the lander has some ultra high definition video but because of bandwidth we haven't seen it yet but as soon as the upload to earth is complete I am hoping we get a much higher resolution video of this landing.
- haolez 3y agoI was thinking more about a recorder positioned on earth or on orbit, but I forgot about the main stage of the ship that deploys the probe and should have visibility of the dark side.
- merrvk 3y agoAmazing, congratulations to all involved. Great day for the nation.
- gabereiser 3y agoCongratulations to everyone involved. This is amazing. India has come so far in its space program. Leaps and bounds. It’s astonishing to witness. While SpaceX has the look - Chandrayaan has the function. Now get Jeb back home!!
- mercurialsolo 3y agoAny space mission is fairly complex no matter the agency private or public. For me the most interesting part to watch personally was the telemetry. What's the latency involved here, do they have agency in terms of manual overrides and intervention in case things go wrong? What does RTT look like, are there more efficient encoding of data to allow minimal information?
- 0xffff2 3y agoLatency is dominated by speed of light delays, which are about 2.5 seconds round trip. Encoding is generally more concerned with data integrity than data minimization. I'm not sure about the details of this mission and whether the Indians have negotiated usage of the Deep Space Network, but with the large antennas of the DSN multi megabit rates are quite achievable.
- cuteboy19 3y agoThere is a latency issue, not a throughput issue
- skynetv2 3y agoDespite all the sour comments trying to find fault and criticize, this is a remarkable achievement, especially on the heels of the failed Chandrayaan-2 mission. Congrats to the team!!! Just 4 years to recover from the failure and achieve a phenomenal success. India just keeps executing despite what others may say. The team deserves even more praise to be able to achieve these wins with limited resources.
- deleted 3y ago[deleted]
- kensai 3y agoAnd a very inexpensive/frugal attempt for that matter! It has been a miracle of cost effectiveness. This is a wonder on its own.
- elevaet 3y agoWhat was the budget, and how does it compare to similar projects?
- Joe_Cool 3y agoAccording to Wikipedia they estimated US$90 Million in July https://en.wikipedia.org/wiki/Chandrayaan-3#Funding https://en.wikipedia.org/wiki/Chandrayaan-3#Funding
- ramesh31 3y ago>It has been a miracle of cost effectiveness. This is a wonder on its own. India has the third highest global GDP by PPP. This is incredibly powerful when you invest in your citizens education the way they have, as the cost of anything like this ends up coming down to skilled labor prices. Their number one competitive advantage at this point is human capital.
- tempnow987 3y agoReally the true wonder! Compare this to the US's SLS plans! The budget is mindboggling.
- bilsbie 3y agoOk dumb question. In the video starting at 13:15, that’s an animation right?
- wheelerof4te 3y agoYes. They didn't have a live feed from any cameras, as far as I can tell.
- itissid 3y agoCongrats to all of the team at ISRO. Assuming the software development for these is non trivial; Its interesting that with the last mission(per Scott Manly) was designed to always select a spot(or more precisely a trajectory) and try hit it. What made them make that decision? Was it like "lets be as precise as we can because we want to get to the spot X because X is special" and thus "Lets let the software always compensate for any errors to get to X". I am assuming that even at this point they tested the software for extreme conditions. It is most likely that once this assumption was made the Software was built that way, i.e: "Lets test the Software can always correct for any issues to get to X with feedback(like thrust)". It trades off Safety for Accuracy(to hit X). This time the idea was "Lets select a trajectory to X" but this time "We will let the software prioritize safety(altitude, speed and heading) to be within norm once we start descending towards X". And additionally "Not make any corrections if we are somehow too far off X if it exceeds safety limits". It trades off Accuracy(to hit X) for Safety.
- dirtyid 3y agoFantastic job. A lot of inspiration for 75M.
- cratermoon 3y agofor the 2023 season: India 1, Russia 0
- abhayhegde 3y agoEspecially impressive when taken into account that ISRO couldn't achieve the soft-landing with Chandrayaan-2 four years ago. One of the big things they changed with this lander compared to Chandrayaan-2 was to increase the landing zone from 500mx500m to 4000mx4000m and adding more sensors and cameras to help the computer find a good landing site. For those who didn't watch live, there was another hover phase (0 m/s descent) at 150m above the lunar surface before final commit.
- sound1 3y agoVery well explained
- ChuckMcM 3y agoThe whole hover and look around thing was super impressive to me. That choice to spend mass on fuel for such maneuvers vs science instruments seems to always go to science in NASA debates and we end up with "either it will land here, or it will die." :-) Great outcome and I look forward to the pictures sent back by the rover!
- bluGill 3y agoA very large number of missions to other planets have failed because they crashed on the planet. Thus anyone who is serious about getting a mission to a different planet will put a lot of effort into the landing system. The fuel burn is cheap compared to a crash landing on the moon (as Russia just had a couple days ago). The above is even at NASA, they have done a lot of complex landing systems over the years. Most missions have several different scientific systems on board. If any one fails well the others still make the mission a partial success. If the landing system fails they all become a failure.
- ChuckMcM 3y agoJust checking in here, did you find something in my writing that suggested I was being disparaging or dismissive of what an awesome accomplishment this is? If so would love to know how you got there so that I could be more clear in the future.
