    Well!! IMO, it is such even with the Chandrayan 2.
    The whole thing was pre programmed and automated .
    The issue here was a logical failure in the instruction set was the velocity which deviated from what was planned.

    Comm black out happened in this case post the crash landing..

    I know that we have pre-programmed spacecrafts with censors which react as per situation faced. Now I don't know whether this FOR-ELSE function can be dubbed as artificial intelligence or not.

    "I Found Vikram Lander!": Meet Chennai Engineer, 33, Who Alerted NASA

    Shanmuga Subramanian was first person to come up with a positive identification. He said NASA's inability to find the lander on its own had sparked his interest.

    Chandrayaan-2: Shanmuga Subramanian spotted the debris of the lander Vikram and alerted NASA.


    READ INOTHER LANGUAGES

    Chennai:
    A Chennai-based engineer has been credited by NASA for alerting them about the presence of the debris of the lander of Chandrayaan 2, India's ambitious moon mission. Shanmuga Subramanian, 33, found the debris from the Vikram moon lander that scientists had been looking for and helped guide them to the spot where it had crashed.


    Indian Space Research Organisation (ISRO) had lost contact with the lander Vikram following its launch from Chandraayan 2 moon orbiter on September 6 when it tried to make soft-landing near the moon's south pole.


    The US space agency made the announcement today, releasing an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft's impact (September 6 in India and September 7 in the US).

    "The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic," NASA said in a statement.

    Chandrayaan 2: NASA released images that shows lander Vikram's site of impact.

    The lander had lost contact shortly before the scheduled attempt to soft-land on the moon on September 7. Days after the failed landing, ISRO said it had located the lander, but hadn't been able to establish communication.

    NASA said it released a mosaic image of the site on September 26 (but taken on September 17), inviting the public to compare it with images of the same area before the crash to find signs of the lander.

    Mr Subramaniam was first person to come up with a positive identification. He said NASA's inability to find the lander on its own had sparked his interest.

    "I had side-by-side comparison of those two images on two of my laptops... on one side there was the old image, and another side there was the new image released by NASA," he told news agency AFP, adding he was helped by fellow Twitter and Reddit users.

    "It was quite hard, but (I) spent some effort," said the self-professed space nerd, finally announcing his discovery on Twitter on October 3.

    NASA then performed additional searches in the area and officially announced the finding almost two months later.

    "I worked hard tracking the intended path of Vikram lander," Mr Subramanian told NDTV. "I am excited. It was lots of hard work. I've always had a passion for space science. I would never miss a launch," the space enthusiast said.

    A top NASA scientist said Mr Subramanian's work was completely independent. "The story of this really amazing individual (who) found it, helped us find it, is really awesome," NASA's Noah Petro told news agency IANS.

    He said that Subramanian "is totally indpendent of the LRO, totally independent of the Chandraayan 2 team, just someone who is very interested in the Chandraayan 2 mission (who) used our data and identified a spot where there was a change that we had not identified".

    "He went through the image, looking pixel by pixel and found that spot," Mr Petro added.

    Is this Vikram lander? (1 km from the landing spot) Lander might have been buried in Lunar sand? @LRO_NASA @NASA @isro #Chandrayaan2 #vikramlanderfound #VikramLander

    India had expected to make space history with the Rs. 1,000-crore Chandrayaan 2 mission.

    A successful soft landing on the moon's surface would have made the country only the fourth - after the United States, Russia and China - to achieve the feat. It would also have made India the first country to complete a soft landing near the South Pole on its first attempt.

    Isro plays down Chennai techie's spotting of Vikram lander

    https://timesofindia.indiatimes.com...ing-of-vikram-lander/articleshow/72357057.cms

    Shame on ISRO for not giving credit to the young lad's discovery.
    If they knew it had crashed on 3rd day itself what the fak were they playing drama for 14 days saying we are trying to talk to vikki bhai.
    Bloody egoistic old buffoons headed by a cry baby boss.
    Dr.Kalam would have handled this very differently.

    This behavior is not that appealing but they may have some other reasons for them to act the way they did.

    ^^ True that.

    So ISRO knew that it was hard landing and debry has fallen all over the place but in parallel they were trying to communicate for about ~2 weeks using dsn network. I think ISRO needs to be more transparent what they thought was recoverable after hard landing.

    Programming a spacecraft does not require Artificial Intelligence. It does however require sound computational implementation of mathematics -- particularly in the areas of mechanics.

    That's why ISRO didn't release pics.. of the crash landing..even though ISRO orbiter has a much better camera resolution of 32 cm...

    Most of us iam sure would prefer scientific results and explanations rather than blind hopes and fantasies.
    Instead of taking the country on a wild ride, proffessionalism entailed ISRO to be upfront about the lander’s fate.

    Not needed. Chandrayaan Programme is to be a long string rather than one or two missions in a decade unlike India's Venus and Mars programmes.

    Better ISRO keeps only one account like NASA to tweet everything and go more into images and infographics than boring texts. That will earn it more than enough international PR.

    Even that Mangalyaan account is dead now. Or they can verify their Isro official YT channel and post videos about their discoveries.
