The second Indian lunar mission "Chandrayan-2" ended in failure, the landing platform deviated from the optimal trajectory during landing on the moon and stopped transmitting telemetry.


The second Indian lunar mission "Chandrayan-2" ended in failure


According to the Indian Space Research Organization (ISRO), during the landing, the Vikram and Pragyan lunar rovers were lost, only the orbital module was left from the mission, which will continue to collect information about the Earth’s natural satellite.

Only 5% of the mission is lost - the Vikram lander and the Pragyan lunar rover, while the Chandrayan-2 orbiter - the remaining 95% - successfully continues to operate in the moon’s orbit

- the message says ISRO.

The Chandrayan-2 lunar mission consisted of three vehicles: a landing platform, a lunar rover and an orbiter, which on September 2 separated from the landing platform and remained in orbit with 125 parameters for 96 kilometers. The mission was repeatedly postponed, but was eventually launched at the end of July 2019.

The landing platform was equipped with five mid-flight engines and eight more engines for orientation. Landing took place in several stages, and it took about 15 minutes to complete.

After the main stage of braking, the device had to hover above the surface to select the final landing area. However, at a distance of about a kilometer from the surface, communication with him was lost. Previously, a deviation from the optimal landing trajectory was noticed. During signal loss, the vertical speed of the device was about 60 meters per second.

Run second in stories India's lunar mission was originally planned for March 2018, but was repeatedly carried forward for various reasons. The first Chandrayan mission was launched to the Moon in 2008 and consisted of a shock probe that collided with the surface at a speed of 1,69 kilometers per second, which led to the ejection of soil from subsurface layers. Remote study of this soil allowed us to obtain several important scientific results.

In the event of the successful landing of the Chandrayan-2 mission on the lunar surface, India could become the fourth country, after the USSR, the USA and China, which succeeded in soft landing.

          It is quite obvious that where igneous rocks predominate, brown shades prevail there. Where sedimentary rocks prevail, the color is mostly gray. Not?

              Brown shades are iron oxide. There is a lot of iron on the moon, but why would its oxide come from there?

              And why not take it?
              Oxygen is one of the most common elements both on Earth and on the Moon.
              This in its free form is very small due to the high chemical activity.
              Almost all minerals contain oxygen.
              The entire surface of the moon of non-oxidized iron do you think? .
              Or do you think that the entire surface of the moon is covered with pure Portland cement?
              The fact of the matter is that the gray color of cement is given by the almost complete predominance of certain types of silicon oxides and calcium oxides, and the almost complete absence of iron oxides - but the moon is full of iron (as you yourself noted).
              The moon is substantially colored with a predominance of brown.
              Such a large celestial body (the Moon is larger than such a colored Pluto) cannot be strictly pure gray.
              But the fraudulent lackeys draw it to an absurdity disgustingly gray.

              Well, why so? From the article titled "THE MOON HAS A DIFFERENT COLOR" it would be most logical to conclude that the Moon is generally multi-colored. Read this work carefully. Here are just some excerpts from there:
              In the Apollo 10 crew report, I'm sorry for the pun, it is written in black and white that the Moon is sometimes light brown, then tan, or dark chocolate. But not gray at all.
              And in some pictures taken from the Apollo 10, it is generally green with bright red blotches.

    The moon landing, and the subsequent separation from the lunar surface, are perhaps the most technically complicated and problematic stages of the project.
    // Only 5% of the mission is lost - the Vikram lander and the Pragyan lunar rover, while the Chandrayan-2 orbiter - the remaining 95% - successfully continues to work in the orbit of the Moon // So with the percentage argued.

      Half a century ago, the Yankees did this without any problems, and even the machines with people were squashed and weaned, but to be honest, knowing the pragmatism and dislike of the American sacrifices
      , their overestimated estimates of their lives, even for this reason alone, not to mention the difficulty of landing and autonomous take-off from the Moon, especially in those days, I do not believe in their stay there at all ... laughing

    By the way, the "GSLV Mk.3" with which it was launched, is it worse than the "Angara A5" in terms of characteristics?

    Who watched the Soviet film Mediator.
    So I think that the Moon is a store of souls, it is still gradually moving away from us.

    Bad.
    Very bad that failed.
    Any information is valuable. If you sniff, you look, maybe something new would be found. And shared, brotherly.
    But without loss there is no success.

    Because you need to cooperate primarily with those who first made the landing, and not a broken bike to blur. What's the saying about fools, smarts and mistakes?

    By the way. And what is the level of cooperation under the program of Indians and Russians. Zero? Just what could they stole?
    PS. We exclude the Chinese because of their economic well-being. They may have an efficiency of 5 percent. what

    sorry device ((. and while in the 21st century, only the Chinese were lucky with landing on the moon. Let's see what will happen next .. when Rogozin promised landing on the moon there ??

      And what is wrong with the first? They worked in the orbit of the moon for 300+ days. I don’t know what period was planned, but this is a considerable duration. Surely not once visited each region of the moon, having received a lot of data.

      Neh you, like the Indians, trusted NASA's landing. I have a little lower about this: Forgot in the article to clarify WHY AND HOW this connection is lost.

    Now the moon FIG knows him in what position the earth is.
    Probably because of the moon one individual, tapped the second in turnips, became impoverished, but next weekend he will not go to the duck, pheasant.

      Where have you seen, a bot-swamp, that the Russians do not like space flights WITHOUT US? You mean that? Did I translate "PASS THEM" correctly? The People's Republic of China has planted its lunokhod - bravo, comrades!

      The space club is expanding, and soon the Indians will visit the moon. The main thing here is the trampolines of the Ragozin-2 Victory and Ragozin-3 models. To make a triumph for conquering the Moon and Mars.
      Why discuss someone else’s garden when Mars and I have the same cookie as Indians and the Moon?

        What trampolines? The Americans needed trampolines. But they were allowed to fly on our rockets. For they have tight with theirs. And with Mars, neither we nor anyone else has cookies. It is not possible to fly there at the moment. And Pts expensive. And India has no problems with the moon. They have problems with landing. For it was controlled by NASA. A little lower about that cookie

      Learn Russian this time and do not use the Ukrainian online translator.
      And two seem to be outside of Tseevrope: howl a goat by the water.
      Why this blurted out then?))))

    They forgot to clarify in the article WHY AND HOW they lost this connection. Landing control went through the NASA Deep Space Network antenna system. It was this American system that suddenly lost contact with the device. And before that, the same thing happened with the Israeli "Bereshit." And the PRC managed the landing itself and landed. Now the question is: does this seem strange to anyone?
    By the way, China’s lunar rover conveyed the color of the surface of the moon. III o-ppa ... it is brown, not gray, as in the photographs of US astronauts. You originally claimed that they shot the FSO with a colored film. Maybe on the moon the flowering season of brown lichens began?))) Or did the Apollos still not fly anywhere?
