Mars, one of the eight planets in the solar system, is the fourth planet in the solar system from the inside to the outside, and is a terrestrial planet, with a diameter of about 53% of the Earth and a mass of 14% of the Earth.

Its axis of rotation and rotation period are similar to those of the Earth, and one revolution is about twice the time of the Earth's revolution.

At the NASA International Broadcasting Center, the host Comoros invited Benjamin Morettia, an expert from NASA's NASA, to ask about Du Xiaosheng's next mission to Mars.

"Mr. Morettia, as we all know, you have a very authoritative voice in the field of Mars exploration, so what do you think of this Mars exploration mission of Du Xiaosheng and others?"

"Manned deep space exploration mission, this is the first time in the world, if this mission can be successful, it will make the Chinese moth become the world's leading country, which is of great significance, first of all, I affirm the contribution of the Chinese moth mission in the history of exploration, but it is not uncommon to be able to reach, the important thing is the next mission."

Morettia has something to say, although this mission, Hua Moth brought a lot of supplies and launched a spacecraft to explore Mars.

But in the eyes of NASA, this move is completely reckless!

Not to mention the amount of materials that need to be carried to Mars, the fuel and food required to return to Mars alone are one technical difficulty after another.

So for NASA, it doesn't mean success, the next Mars landing is the key.

The host Comoros naturally has ulterior motives for setting up this special broadcast analysis.

In his opinion, no matter whether Du Xiaosheng succeeds or not, with the hot influence of this incident, his show can become a big hit.

And he himself has the same opinion as Morettia, and he does not believe that Du Xiaosheng can succeed.

At this time, hearing the expert say this, Comoros asked very "skillfully": "Just landing is already significant, what if the sample is completed and returned to Earth?" ”

Morettia replied without hesitation: "On this basis, if the return of Mars samples is completed as scheduled, it will be an extremely extraordinary achievement in the history of human deep space exploration." Of course, this is difficult to do. The corners of the old expert's mouth hooked up a smile of unknown meaning, although there was no problem with the words on his mouth, but the mockery on his expression was self-evident.

In his opinion, the difficulty of Mars exploration is extremely great.

This is not only a series of problems such as fuel, distance, load, weight of falling into the atmosphere, and the difficulty of getting rid of the gravitational pull of Mars, but also a major challenge for human science and technology.

And Hua Moth will overcome all the difficulties in one breath this time, and this chance is obviously impossible to complete.

The Comoros pretended not to understand, looked like they were curious and exploratory, and asked in an inquiring tone, "Is it?" Isn't it more than half of the success to reach the orbit of Mars? ”

"As I said, so far, mankind has carried out a total of 44 Mars exploration missions, and among these 44 exploration missions, 18 have been completely successful, so for the most difficult, landing exploration mission, a total of 19 have been carried out, and only 9 have been completely successful and partially successful, with a success rate of less than half. So these data show that it is quite difficult to reach Mars and complete the landing. Of course, most of this exploration is done by NASA. This exploration of the Chinese moth is very bold ......"

As a scientist, Morettia knows how to put his point across in words.

He did not directly state his point of view.

Instead, he gave a series of data directly, which indirectly illustrated how difficult the plan was.

Comoros added: "Just a probe landing with less than half the success rate? ”

"Therefore, Hua Moth's plan this time is still very stable."

"Their manned space program is still relatively thorough, and after reaching the designated orbit, the pilot will first drop the supplies."

"This should contain fuel, landing robots, various scientific equipment, food, and the necessary materials to build the base. This will be the key of the key, the hard of the hard. The gravitational pull on Mars and the friction of the atmosphere during landing, as well as the situation on the ground, will become scientific problems. If something goes wrong with the supplies, it is safe for the astronauts to choose to fly around the fire instead of landing. ”

Although the Mars landing technology is now becoming more and more mature, the more materials are delivered, the greater the danger will be, and any slight omission will turn the mission into a flight around fire.

At this time, in the cockpit, four astronauts performed their duties, wearing earhooks and waiting for instructions from the ground command center.

Du Xiaosheng sat in the position where the captain was, his heart was full of excitement and shock, and the huge orange planet in front of him was full of shock.

As a desert planet, the surface of Mars is made up of sand dunes, gravel, and no stable bodies of liquid water.

Its atmosphere, on the other hand, is dominated by carbon dioxide, which indirectly causes its atmosphere to be both thin and cold, with sand and dust suspended in it, and dust storms often occur every year.

Entering the orbit of the satellite, through the instruments on the spacecraft, Du Xiaosheng can clearly see the situation on the surface of Mars.

Mars is less geologically active than Earth, and most of its surface features were formed during the more active period of antiquity, with craters, volcanoes and canyons, including Mount Olympus, the highest mountain in the solar system, and Mariner Canyon, the largest canyon. Another topographical feature is the stark difference between the northern and southern hemispheres: the south is an old, crater-filled highland, while the north is a younger plain.

"Enter the orbit of Mars and apply for a survival landing option."

With the launch of the satellite's orbit, the spacecraft's simulation system has begun to help Du Xiaosheng find a place to drop supplies.

To establish a Mars base, mankind planned eight suitable locations for the establishment of the base as early as 20 years ago.

As the first Martian base, Hua Moth is quite cautious about the choice here.

First of all, there must be a water source near the base, and it should not be too difficult to mine, and secondly, it must be close to the mountain, and you can dig a hole to avoid dust storms and cosmic rays.

Secondly, the latitude should not be too high, Mars has spring, summer, autumn and winter, and the location near the equator is chosen to make the climate more livable and make the growth of plants better.

After full arrangement, the system immediately locked the No. 4 survival point according to the location of Du Xiaosheng and others.

At this time, the ground command center finally gave a reply six minutes after the request was issued: "Select the No. 4 survival point and conduct the launch test!" ”

"Roger! The supplies will be launched in ten seconds! As the captain Du Xiaosheng pressed the launch switch, the seven cargo compartments completed separation and fell towards the Martian atmosphere ten seconds later......
