Xun Pang Xuelin, wearing an EVA spacesuit, stood on the top of a small hill.

It's noon. The sky on Mars is a hazy yellow-brown. There is more hematite on the surface of Mars, and the color is reddish. This light is reflected into the atmosphere, and there is a lot of dust in the atmosphere of Mars. Particles, so the Martian sky looks a bit closer to the color of sandstorms on Earth.

But in the morning or evening, the atmosphere of Mars will turn red or pink again. This is because the Martian atmosphere is more likely to accept longer-wavelength infrared light, and because of atmospheric particulates and reflections from the surface of Mars, this color will appear.

The rover stopped at the foot of the mountain and was charged, Pang Xuelin rose up, and climbed up the hill to admire the beauty of the red planet.

Looking afar, you can see hills showing various beautiful streamlines in the desert. Most of these hills are gentle and beautiful in shape, which is the result of hundreds of millions of years of ancient wind and sand.

Entered the world of "Mars Rescue" for more than a month, Pang Xuelin had the first time to enjoy this desolate and lonely alien world.

In the past few days, Pang Xuelin set off every day at dawn, washing and eating, inspecting the air composition in the car, checking the oxygen tank and replacing the carbon dioxide filter, and then driving for about three hours, finding a place to park, performing EVA, and turning the solar energy in the compartment. Take out the battery panel and charge the rover with the solar panel on the roof.

After charging for about four hours, he returned to EVA again, put away the battery panel, and then kept driving until it was dark and found a place to rest.

的 Long-distance travel is boring and regular.

After spending nearly half an hour at the top of the hill, Pang Xuelin returned to the narrow rover with some boringness.

The interior space of the rover is not large. Food and equipment occupy a lot of space, and barely leave a small bed for Pang Xuelin to lie down.

的 The heat provided by RTG is very powerful, which can keep the rover at a constant temperature of 25-30 degrees.

Take off the bulky EVA spacesuit, Pang Xuelin can wear a T-shirt and big pants, and wrapped in a blanket to sleep inside.

The life of a truck driver like this on the earth is not comfortable. The most troublesome thing is how to deal with excrement.

There is a toilet in the roamer, but this toilet only has a sewage tank for emergency use, and it is not connected to the water circulation system in the car.

So Pang Xuelin can only deal with the problem of urination and separation separately. The large size is relatively simple and can be solved in the toilet. He specially prepared a bottle and poured urine into the water circulation system after the solution. Then ...

Forget it, let alone, the author Jun feels disgusting.

He left the perch for three days, and Pang Xuelin missed the life of the perch.

In three days, Pang Xuelin crossed the Asidalia Plain and entered the hilly area, but there is at least one or two days' journey from the destination. According to the map, after Pang Xuelin crossed the hills, he had to cross the Chris Plain and enter Azerbaijan. Reese Valley.

Jain is a delta area that hits the river bed and is also the landing area of ​​the Mars Pathfinder.

But it is not easy to find the position of Mars Pathfinder.

The navigation beacon of the perch capsule is only forty kilometers. Although there are relatively complete topographic maps on the computer, Pang Xuelin finds himself taking it for granted.

Because of the landmarks on the map, he couldn't find it at all.

The compass is even more meaningless, because there is no magnetic field on Mars.

However, Pang Xuelin has his own method. Forbes (Fei Wei), who rises west and falls twice a day, is his best partner.

Although there is no way to use Ferpos for precise navigation, you can measure the approximate position.

That's why he can enter Chris Plain all the way.

But after entering the Chris Plains, Pang Xuelin found trouble.

大 This great desert has a great view, and there is a dark flat land everywhere. There is no reference at all.

Going out for more than ten kilometers and twenty kilometers, it's like staying in place.

Xi Pang Xuelin drove the Chris Plain for a day with reference to Forbes, but the expected Ares Valley never appeared.

Pang Xuelin wondered if he was driving in the wrong direction. It wasn't until the morning of the fifth day that Pang Xuelin felt that he was working.

Because he found an excellent reference-Hammer's impact crater.

撞击 The impact crater named after the town in Piper's fairy tale has a diameter of ten kilometers, the coordinates are 20.2 degrees north latitude and 32.8 degrees west longitude.

So Pang Xuelin knew that he was not far from Mars Pathfinder.

下午 On the afternoon of the fifth day, Pang Xuelin drove his rover across the Chris Plains and entered the Ares Valley.

The road started to become rugged, and some stones of various sizes appeared on the road from time to time. Fortunately, the chassis of the rover was high enough and the off-road performance was quite good.

That night, Pang Xuelin parked the rover near a boulder as his own camp, and took a solid sleep.

一 In the early morning of the sixth day, Pang Xuelin raised his spirit and began to search slowly in the Ares Valley.

After a day of searching, Pang Xuelin finally found the landmark he was looking for—Shuangfeng.

Twin Peaks is a very famous photo taken by Mars Pathfinder, consisting of two very close hills, and Mars Pathfinder's ... landing point is exactly one kilometer west of Shuangfeng .

Dr. Pang Xuelin drove all the way, and finally, not far from the west side of Shuangfeng, he found the Mars Pathfinder which was tightly wrapped by airbags and half buried in sand.

"I finally found you!"

Xi Pang Xuelin could not help but breathe a sigh of relief.

Before setting off, he and Watney had agreed to search the Ares Valley for up to a week. If the Mars Pathfinder could not be found, they would return immediately.

Today, it took him only two days to find the target, which is very smooth.

The Mars Pathfinder is a tetrahedron wrapped by an airbag. When flying to Mars a certain distance, the "Mars Pathfinder" spacecraft begins cruising to prepare for the release of a parachute. At a height of 5 to 11 kilometers above Mars, a huge parachute with airbags opened, then floated down quickly. At a height of 300 meters, the flying bag automatically inflates and expands ... Finally, it leaves the parachute and bounces to land on Mars. After the landing is completed, the airbag will deflate, exposing the Mars Pathfinder inside ~ www.novelbuddy.com ~ The Mars Pathfinder consists of a landing capsule and a sojourner Mars rover. The landing capsule is not movable. The sojourner Mars roams at a turtle speed of 2 feet per minute to detect rock components on Mars. He was the first Mars rover in human history and played a very important role in the process of human detection of Mars.

Xuan Pang Xuelin found the Mars rover, which had been parked for nearly 40 years, 30 meters away from the landing capsule.

But the most important communication equipment is still in the landing module. The landing module was too large for Pang Xuelin to remove. He only needed to remove the communication system and the Mars rover.

Why bring the Sojourner Mars? The reason is very simple. People on Earth want to contact the Mars Pathfinder, and can only send fixed instructions, such as moving the Mars rover back and forth, and this fixed instruction has no meaning to Pang Xuelin.

He needs to translate this instruction into understandable text, so the rover with a rotatable camera becomes the best choice.

At that time, as long as he produced the corresponding alphabet, and then used the rotatable camera of the Mars rover, he could have a conversation with Ares Project Command.

Everything is going smooth.

Pang Xuelin tied the rover to the landing module with a hinge, and then drove the rover to pull the landing module out of the sand.

Then, using various tools carried in the car, he separated the main system of the landing module from the heaviest soft landing system.

Finally, he threw the ten-kilometer Sojker Mars rover into the rover. The landing system, which weighed nearly 100 kilograms, was placed on the body of the rover.

Pang Xuelin is glad that Mars' gravity acceleration is only half that of the Earth, otherwise he would not be able to do this job at all.
