Tianwen 1 and Chang e 5, whose technology is more difficult?

Chang'e-5 is a bit more difficult, because Chang'e-5 took longer to prepare and develop than Tianwen-1.

Compared with Tianwen-1, Chang'e-5 has not been verified except for the rover leaving the lander, which has been verified in Chang'e-3 and Changwen-4, and Tianwen-1 is better than Chang'e-5 in terms of quantity and communication difficulty! However, the return of Chang'e-5 from the surface of the moon is also unprecedented in the history of China's aerospace industry, and the difficulty is also very high! For China's aerospace, there is no more difficult, but "Xiongguan Mandao is really like iron, and now it is stepping forward from the beginning"!

Tianwen-1 technology is a bit more difficult because it involves a complete system of orbiting, landing, and detection.

I think Tianwen-1 is more difficult, the distance is long, the electromagnetic environment is complex, and the Martian environment is unknown, so Tianwen-1 is more difficult!

The Chang'e-5 probe has successfully landed on the moon! Compared with Tianwen-1, which is more difficult.

I haven't read the article yet, so I guess that Chang'e-5 should be more technically difficult.

In terms of quantity and communication difficulty, Tianwen-1 defeated Chang'e-5, but Chang'e-5's return from the lunar surface is also unprecedented in China's aerospace history, and the difficulty is also very high.

Tianwen-1, because of its relatively long distance, will open a parachute at supersonic speed in the Martian atmosphere, and also use dynamic hovering to evade.

Shenzhou 5 went to the sky first.

Shenzhou-5 is the fifth in the Shenzhou series of spacecraft and China's first nuclear-manned spacecraft, which was launched from the Jiuquan Satellite Launch Center at 9 o'clock on October 15, 2003, sending Yang Liwei, a member of the astronaut Liang Tianyuan, and a Chinese flag of special significance into space.

At 23 o'clock on December 8, 2018, the Long March-3B-2 carrier rocket successfully launched the Chang'e-4 probe, opening a new journey of lunar exploration.

It must be that Tianwen-1's technology is more difficult, because his technology is too complex, and his equipment is more perfect and accurate than Chang'e-5. Although the China National Space Administration announced on July 17 that Tianwen-1 will be vertically transported to the launch area of the launch station 101 area, but he will be launched from the end of July to the beginning of August, obviously all onlookers are very confident about the launch on July 23, of course, there is another bright spot in 2020, that is, Chang'e-5 is also expected to be launched at the end of October.

The missions of the two are somewhat similar, but not completely identical, so there are many people here who are asking, if the two of them compare, which one is more technical, we have to understand Mars first, we are about 55 million kilometers away from the Earth, which does not seem to be very far. However, due to the difference in speed and Earth's orbit, the two are approaching each other about once every 26 months, so the upcoming Martian year 2020 is once again the peak year for Mars exploration, and Tianwen-1 actually has three main projects.

That is, the orbiter, the lander and the patrol device, the total mass is about 5 tons, of which the mass of the orbiter is 3 175 tons, and the mass of the patrol unit is 240 kg. Its dimensions are approximately: 2 0 meters 1 65 meters 0 8 meters, respectively, to complete Mars exploration and landing patrols, will be the distribution and detection of the Martian soil environment, atmosphere and water, search for life on Mars, it will also detect key information related to life, such as the Martian magnetic field.

In addition, the orbiter around Mars will also complete the task of relaying communication between the landing vehicle and the Earth. The patrol also carried ground-penetrating radar to investigate the soil beneath the surface of Mars and its thickness and composition. In addition, it carries navigation cameras, a Martian landmark composition analysis tester and a multispectral camera, as well as a Martian surface magnetic field detection detector and a Martian meteorological surveyor.

The Chang'e-5 probe has successfully landed on the moon! Compared with Tianwen-1, which is more difficult.

Although both are very difficult, in general, the technology of Tianwen-1 is more difficult, in terms of quantity and communication difficulty, Tianwen-1 is completely better than Chang'e-5, and other systems are also more technically challenging.

Tianwen-1 and Chang'e-5 are technically more difficult, but Tianwen-1 has a higher breakthrough than Chang'e-5.

In terms of probe complexity, Chang'e-5 is higher than Tianwen-1, and in terms of difficulty in deep space exploration, the Mars mission is higher than that of the Moon. So far, lunar sampling has been successful in the United States, the Soviet Union and China. And the landing on Mars has succeeded only in the United States.

The Soviet landing on Mars cannot be counted because there is no return to the landing**.

At 19:52 on February 10, China's first Mars exploration mission Tianwen-1 successfully entered the Mars capture orbit, which marks that China's Mars exploration program has entered a new stage, and Tianwen-1 will enter the depth of the landing site on Mars in the Mars orbit, and will implement the mission of lander landing on Mars around May this year. However, due to technical limitations, the U.S. lander at that time did not take the Mars rover to carry out mobile exploration of the Martian environment, so from the current point of view, the starting point of our Tianwen-1 is higher than that of the United States, and if China's Tianwen-1 mission is successfully completed, China's Tianwen-1 technology will become the world's second only to the United States Mars probe technology.

Because the United States has started the Mars exploration program as early as the 70s of the last century, and although the former Soviet Union also announced that it would explore Mars, their cumulative 20 exploration missions have not been completely successful, and Europe has abandoned this plan after two attempts, all of which have led to the fact that the outstanding talents of the former Soviet Union and Europe finally chose the United States, which was still the only one to carry out Mars exploration research at that time, and the United States' Mars program was also in a leading position in the world due to the addition of these talents.

China's Tianwen-1 and its lander and probe are completely independent research and development, just like China's space strategy, are from scratch, so in the first Mars exploration program has successfully surpassed the former Soviet Union and Europe's achievements, the next Tianwen-1 landing and exploration mission will determine China's future Mars strategy height.

Tianwen-1 will first perform a deceleration action after braking into the orbit of the Mars satellite, and finally reduce the speed of kilometers per second to meters per second, and then the landing site will be explored to avoid obstacles on the ground, and then the landing and patrol exploration missions will be launched, so that we can patiently wait for the good news of success.

It is already considered first-class in the world, Tianwen-1 combines the characteristics of all the previous satellites, and adds many new functions.

At a relatively high-end level, there are very few countries in the world that can achieve the success of this technology, so China is also very good at mastering this technology.

It belongs to a very high level in the world, and this technology is also very mature, and it is already very first-class in the world.

This technology is at the leading level in the world, and the human desire for space exploration has always existed, and the technology is constantly evolving.

After the successful launch of Tianwen-1, what is the level of China's aerospace in the world?
