How low is the temperature of ice? Ice formed by water alone is usually below zero, and the temperature of ice formed by some gases is much lower, minus 1200 degrees is normal, if the ice formed by water is also more than minus 100 degrees, then there will still be life?

Mars is a magical planet, with a golden surface like a ripe wheat field, and the truth is an endless desert. Near the equator, the terrain is smooth and supple, and the terrain is slightly undulating, and when you turn half a circle, you will see a large dark ravine, whether it is a dry riverbed or a cooled magma gully, it is unknown.

Soyuz-6 spacecraft, this is the Mars 3 base, please answer if you receive it!

Well, this is the Soyuz-6 spacecraft, how are you preparing there?

Whew, everything is ready.

Okay, see you in twenty-seven minutes.

Good.

Soyuz-VI spacecraft as usual. With the living materials, he slowly landed in the No. 3 base, and after unloading the materials he brought over, he was about to carry out another mission.

Soyuz-6 usually has only four members: the captain, pilot, medic, and engineer. This time I needed to carry out a mission, so I brought two more scientists, a man and a woman, two biologists.

Hey, how are you doing?

The driver, Xiao Wang, is an old acquaintance in the base, and he has been here not five times but four times, as if he was at his own home, he took out a bottle of drink from the refrigerator at will, sat on the sofa, and looked at Xiao Feng who was drinking tea opposite Erlang's legs.

Xiao Feng raised his eyes and looked at Xiao Wang, continued to stare at the tea leaves in the tea, and then looked at his fingers, a little unwilling to speak.

Well, seeing how depressed you look, I'll promise you, but I have one condition.

When Xiao Feng heard this, he raised his head and looked at Xiao Wang, not showing a happy expression, but a look of loss.

Before coming, Xiao Wang wanted to live in Xiao Wang's room, but Xiao Feng didn't agree, he didn't like people who didn't like cleanliness, especially the sloppy Xiao Wang. Xiao Wang made an suggestion that he could spend his own money to give him an extra box of books. What books do you need to hold in this box of books, let Xiao Feng make a catalog, and he will buy them.

Xiao Feng is a person who likes to be quiet and clean and tidy, a crepe person, but as a meteorologist, he likes to walk around outside, wearing a spacesuit, facing the big sun, facing sandstorms, and installing meteorological instruments in the endless desert.

Here, this is the catalog, I advise you to buy it quickly, otherwise, you may have to experience a wind and a meal these days.

Xiao Feng put the note that had been prepared a long time ago on the table in front of him, took a sip of tea, and looked at Xiao Wang.

Why?

Xiao Wang took the note and glanced at it, it was full of strange titles, none of which he knew, and then when he heard Xiao Feng say this, he couldn't help but be surprised.

Well, the two rooms that have been vacated here have been given to the two biologists, and you can either sleep on the couch or in the spacesuit, you can figure out what to do yourself.

Xiao Feng didn't reply, and after speaking, he got up and left.

No way!

Xiao Wang looked at the back of Xiaofeng who left, leaned on the sofa, was so angry that he was about to throw away the note, and put it back in his pocket with a wave of his hand.

Before the task can be carried out, people need to debug the equipment, which takes about three to five days. Taking advantage of this leisure, Xiao Wang planned to go out with Xiao Feng. But Xiao Feng didn't agree, but the stationmaster insisted that he had to do this, which made Xiao Wang proud.

Along the way, Xiao Wang kept whistling and couldn't stop, Xiao Wang said that he had said several times, but he didn't change.

The weather was nice on this day, with winds below four meters per second and it was quiet. Watching Xiao Feng seriously check the weather instrument, Xiao Wang felt a little bored, so he came to a nearby hill a little higher, and looked up, it was all sandy wasteland.

Hey, there's a pit over there, have you been there?

Xiao Wang pointed to the dark place in the distance, calling out for Xiao Feng's attention.

No.

Don't you want to check it out?

Don't want to.

Okay, let's go and have a look.

Don't go.

Hey, I've promised to buy you books, why do you still have this attitude?

My attitude? Yes? Why don't you wash your feet before going to bed at night?

Uh, that's it?

Yes, what do you think?

You said it earlier! You said I would have washed it a long time ago.

Hmph, it's late.

Well, I apologize, I'm sorry, next time I'll definitely wash my feet, okay.

Okay, forgive you for now, if you don't wash tonight......

Rest assured!

It took more than ten minutes, and after checking all the data recorded by the meteorological instrument, Xiao Feng accompanied Xiao Wang around.

At this time, the sun is 30 degrees above the horizon, and there are some deep pits on the ground that do not shine on the sun, and it looks very dark and prominent on the golden ground. According to the temperature displayed in the spacesuit, the temperature on the surface is only 10 degrees Celsius, and when you come to the pit, the temperature drops to minus 3 or 4 degrees.

The bottom of this pit is different from the outside, here it feels like the sand is firmer, and it feels hard when you step on it, as if it is some kind of sedimentary layer. It took a little effort for Xiao Wang to cut off a piece from the bottom of the pit.

The color is slightly darker, the sand is mixed, there are sporadic metallic flashes, the texture is hard and not fragile, and it can be deformed and not dispersed by pinching.

You say, will there be water in there?

Xiao Wang had long heard that water had been found on Mars, but he had never believed it, and now looking at this somewhat wet soil, he couldn't help but think of this.

Probably not, the surface water of Mars is only distributed in the polar regions, where the temperature is low enough to retain water, and the temperature here is too high, even if there is water, it will have long been sublimated.

Xiao Feng rarely had the patience to explain to Xiao Wang, and after finishing speaking, he continued to observe the surrounding mountain walls.

Oh, wait a minute, you say it's too cold here? It's minus six or seven degrees, and it's still high? How low does it have to be where there is water?

Xiao Wang's surprised tone made Xiao Feng feel that Xiao Wang was illiterate, except for a few turns of the steering wheel and a few buttons, nothing else.

It's okay for you to freeze to death.

Xiao Feng looked back at Xiao Wang and said in a cursed tone.

Cut, I don't believe it.

Xiao Wang glanced at Xiao Feng with disdainful eyes, and casually threw out the sand that had just been picked off, he didn't notice that there were a few grains of sand stuck between Xiao Wang's fingers.

The diameter of this deep pit is about fifty or sixty meters, and the elevation of the lowest part is minus ten meters, which is considered a small pit. There is not much to see except for a crater-like circle in the middle. After a turn, the two left.

The bottom of the pit was originally clean and level, but because of the arrival of the two, in addition to a few shallow footprints, one place was destroyed, and that was what Xiao Feng picked out not long ago. At this time, the clod of soil that was thrown away by Xiao Feng was slowly softening, and it took more than two hours to melt into the ground, and the pit that had been cut out over there was slowly filled. All other footprints were gone, and everything was back to normal.

On the space station orbiting Mars, an astronaut looked through the porthole and saw a yellow ripple rolling slowly on the Martian ground in the distance.

At the same time, Xiao Wang and the others also received the news that a huge sandstorm had been generated, and it would arrive at the base in three hours, so that Xiao Feng and the others could come back quickly.

He didn't care about checking any meteorological instrument, Xiao Wang pulled Xiao Feng into the car and hurried back to the base as quickly as possible. At this time, the two of them were about seventy minutes away from the base, and if nothing else, they would definitely be able to return to the base safely before the sandstorm arrived.

Don't worry, we'll be back.

Xiao Feng's rare nervousness made Xiao Wang, who was always broad-hearted, scared.

You drive your car, don't look at me.

Oooh oh.

Time passed very slowly, and after driving for more than an hour, Xiao Wang still didn't see the flag in the base.

The site selection of the base has gone through a round of screening, and it is selected on a large plain with flat terrain, and the terrain within a radius of more than 10 kilometers is undulating no more than 10 meters, and the 27-meter-high flag erected in the base can be seen from a long distance, plus the color is blue, and the naked eye can see it at a distance of two or three kilometers.

Damn, the base won't run away, right?

After driving for almost an hour and a half, I still can't see the base, not even the flag of the base, and Xiao Wang, who is usually hippie and smiling, has a solemn face.

You're not going to get lost, are you?

Xiao Feng was calm, checked the familiar data on the weather instrument, and said casually.

How is it possible, don't you know that this car has a navigation system?

As soon as Xiao Wang said this, he glanced at the screen showing the navigation route.

it! It's over, it's over!

Xiao Wang shouted, quickly stepped on the brakes, his face turned pale with fright, and slowly tilted his head to look at Xiao Feng.

What kind of pinch did you make? Don't go away, after today, come back tomorrow.

To be continued......
