India's "Chandrayaan-3" finally stumbled into lunar orbit under the global attention, began to separate the lander and landed on the moon, but on the other side, Russia's "Luna 25" also silently entered the lunar orbit and will land on the moon, and India and Russia have landed on the moon for about the same time, Russia is about 2 days earlier than India. Many people may be curious here, India's "Chandrayaan-3" was launched last month, Russia's "Luna 25" was launched only this month, why did Russia's spacecraft land on the moon first than India?

Through relevant reports, it can also be known that India's "Chandrayaan-3" was launched on July 14, while Russia's "Luna 25" was launched on the 11th of this month, but it should be noted that India's "Chandrayaan-3" took 22 days from launch to lunar orbit, while Russia's "Luna 25" took only 4 days from launch to lunar orbit, and it is this efficiency that allows Russia's lunar exploration spacecraft to land in advance of India. The reason for this is that India's technology and funds in this regard are a little insufficient, the "Chandrayaan" rocket looks very tall and powerful, carrying a lot of fuel, but in fact the thrust is not enough, the launch probe is also heavier than Russia's, reaching 3.8 tons; and this is India's last moon landing, because the previous failures made the Indian government significantly cut the cost of the project, this time in order to achieve the moon landing or patchwork, a lot of designs are streamlined results. But this still does not support sending Chandrayaan-3 directly to lunar orbit, so the Indian space department has adopted a compromise approach; Send the spacecraft into a geosynchronous transfer orbit, and then accelerate again and again through the engine, and finally push the apogee up to enter the Earth-Moon transfer orbit, which is why the "Chandrayaan-3" rocket is so big, because it has to load a large amount of fuel to promote the orbit change of the spacecraft; And there was also a mistake in the earth's orbit, which led to 6 orbit changes before it was successfully sent.

Russia is different, Russia's "Luna 25" rocket thrust is enough, there is no need to save so much money to go to the moon slowly, after all, the longer it takes, the more problems there will be, so even if the Russian spacecraft is launched late, the time to enter the lunar orbit is not slower than India's "Chandrayaan-3", and even a few days in advance to land. According to the plan, Russia's "Luna 25" will land on the moon on the 21st, and India's "Chandrayaan" will not land on the moon until the 24th, if nothing else, Russia will become the first country to land on the south pole of the moon, and compared to India, Russia's technology in this area is obviously more mature.
Don't look at China and the United States have begun to land manned on the moon, Russia is now reduced to competing with India for the title of the first country to land on the moon, but in the last century Russia's space technology is the world's top, the world's first country into space is the Soviet Union, even the only country in the world that has achieved a manned moon landing - the United States is behind the Soviet Union; It's just that after the collapse of the Soviet Union, Russia's economy was too crotch-pulled, coupled with a large number of brain drains, Russia's space industry collapsed, and it was only revived when the world opened space competition, but even this original technical base was enough to crush a number of countries.
However, by this point, some people may be curious, so who is more advanced than the mainland's Chang'e-5 spacecraft launched by Russia? Chang'e-5 is a lunar exploration spacecraft launched by the mainland 3 years ago, in fact, the spacecraft launched by Russia is only equivalent to the Chang'e-3 launched by the mainland 10 years ago, both of which are a landing probe, just to achieve the landing on the moon; The continent's Chang'e-5 is different, it not only landed on the moon, but also collected 1731 grams of lunar soil on the moon and returned it to Earth for study. For Russia, this time can only be regarded as a return to the moon, after all, the Soviet Union has achieved the sampling of Chang'e-5, but it is not as good as Chang'e-5 in quantity, if Russia wants to catch up with the progress of the continent, I am afraid that the first thing to do is to "archechaetic" the technology of that year to see if it can replicate the moon landing technology in the Soviet Union.
