Chapter 380
Zhao Yanling did the work of four people by himself, and finished it easily, which saved at least half an hour compared to the cooperation of four people.

This made Samantha and the others dumbfounded.

"Although I can't understand it, I can read the shock from Kate's expression."

"I feel that Lao Zhao is very relaxed. Could it be that going to space is also an overkill?"

"This is my idol, only this kind of person is qualified to be an idol."

After changing the engine is the first step. In the second step, they have to divide into two groups, one way to fill up the fuel, and the other way to fill up the cargo hold carrying the three people's life-saving supplies.

Zhao Yanling and Samantha went to the cargo hold, and Alexander went to fill up the fuel.

With the help of the robotic arm, this side will be completed quickly.It's also faster there because there's not much work to get started.

How to place the sustaining materials has already been planned.Maximize the use of space and meet every need, this is the normal state of the spacecraft.

After the work was completed, Samantha said: "Three, next, let me treat you to a meal. What kind of meal do you suggest? I have collected a lot of good things here."

Kate glanced at Alexander: "Is there any Russian food? I've always wanted to try it."

It didn't matter to Zhao Yanling, he came prepared, and he would make whatever he wanted to eat later.

Samantha nodded: "Coincidentally, there are red cabbage soup and stew, so let's eat this."

She ran to heat the food, and the soup could be eaten directly, and the stew was not much trouble.

The food is heated directly in the container and eaten directly after it is ready.

The dining table is folded and is usually integrated with the wall.

After opening, the tableware is made of magnetic materials that can be adsorbed and fixed on the dining table.There are rough grooves on the dinner plate that can fix space food of a specific shape, so astronauts can eat at will.

However, before eating, you need to fix your body with straps.

Seeing that Zhao Yanling did not move, Samantha pointed to a device similar to a seat belt.

Zhao Yanling smiled and shook her head: "I don't need to bother, just eat like this."

Kate said: "If there are food residues falling at that time, you can use the fan to suck it yourself."

However, in reality they were overthinking.

Zhao Yanling eats like usual, except there are no stools and chairs.He controlled the dining table with one hand and started eating with a spoon in the other.

Including drinking coffee before, and drinking soup now, are far from as good as the audience imagined.

No matter how scientifically the container and the plate are made, when the fluid is sucked up, it must condense into a ball. Drinking water is not drinking, but swallowing.

Soup is more troublesome. The residue in the fluid is likely to enter the esophageal tube by mistake and get stuck.

Therefore, you must be careful when eating in space.

Fortunately, the human esophageal tube will move.

If you can't move, you don't even know how the food will fall into your stomach.

Waiting for the food to enter the stomach, there is still trouble.That is food and soup, which will keep rolling in the stomach.You can understand the taste when you think about it.

Samantha joked: "On the bright side, if we eat in space, we won't suffer from gastroptosis, haha..."

A look of memory flashed across Alexander's face: "With the continuous advancement of science and technology, the continuous improvement of rocket transportation capacity, storage means and heating means of the space station, the situation has become much better. It turns out that we can only eat food in one bite. It is in a packaging bag. It must be designed in this way to prevent the residue from affecting the air in the space station. It is precisely because of this that the food at that time was either mushy or lumpy. At that time, we called this kind of food 'Nutrition toothpaste', you can imagine how unpalatable it is, no matter the taste or texture. Our Russian astronauts always think of various ways to bring something into space, haha, because the journey is too long, I Just announced this secret. Before, I secretly brought vodka into space. The result? Weightlessness will affect the taste buds. At that time, I drank two sips of vodka, and the Japanese sake I tasted was bland and tasteless.”

He is the oldest and has worked in space for the longest time, which is already a memory of bitterness and sweetness.

If you look at it this way, the situation is indeed much better now.

Samantha said: "Then you are miserable. Like me, I brought all kinds of Italian food. Lee from Korea brought wakame soup and Korean barbecue and rice bowls. Japanese astronauts even brought As many as 27 kinds of food have entered the space station, and you can eat in different ways. These red cabbage soups and stews are still brought by your Russian astronauts.”

Their dialogue opened the eyes of the audience.

"It turns out that life in space is like this."

"It hurts me to say that."

"Hold on, Old Zhao."

After eating, it's time to say goodbye.

Zhao Yanling and the others put on their space suits.

Samantha was also a little emotional.Space operations in low-Earth orbit are completely different from long-distance voyages.At least, the mentality is different.

She said: "The most I have ever worked on the space station is 200 days. I thought it was long enough, because this record is only kept by me. But now compared with your schedule, I am nothing. Perhaps, because you I am confident to set another record. Goodbye, my friends, when you come back, maybe I will still be here!"

Zhao Yanling waved her hand: "Samantha, when I come back, I'll treat you to dinner. Let me tell you a secret, I have many restaurants, including all the cuisines in the world. Goodbye..."

Out of the space station, through the orbital module, back to the spacecraft.

Loneliness surrounded the three of them again.

This is just a few meters, across the loneliness and hustle and bustle.

Alexander commanded: "Check the status!"

The training steps flashed through Zhao Yanling's mind, and they were strictly implemented according to the standards.

He looked at the various data on the screen: "The yaw angle is 16 degrees, normal."

After checking the fuel tank, Kate said: "The attitude control program has been closed, and the status is 100%."

Zhao Yanling stared at the data closely, and the time passed by every minute.

He said suddenly: "Enter the periapsis and start the ignition process."

Alexander ignited, the vacuum engine sprayed flames, the three were pushed tightly against the back of the chair, and the spaceship began to accelerate.

First, enter the elliptical transfer orbit.

Zhao Yanling said: "The yaw angle is fixed, the second acceleration!"

Feeling the push back again, the spacecraft continued to accelerate.

After two accelerations, Zhao Yanling stared at the data, and when it reached a certain value, he said, "The position of Mars is 42 degrees 29, and the course inclination is slightly adjusted by 1 degree."

The command center on the ground rejoiced, and people clapped hands.

Countless people breathed a sigh of relief, at least the beginning went smoothly.

Command center: "Zhao, you did a good job. I can consider giving you a salary increase. Maybe it will give you money to open another restaurant."

Zhao Yanling, an astronaut, does not work for nothing, he is also paid, and the salary is not cheap.

Kate also relaxed. In fact, the most technical part is the beginning of the voyage, but the rest will be easier.

But she still joked: "Guys, don't rush to celebrate, you have to open the mast."

Space navigation, in addition to liquid fuel is a very important part, but also solar power.Their lives are inseparable from electricity.

Alexander, the old guy, laughed: "If NASA can even make trouble with this, then I will underestimate you."

Command Center: "Be careful, we can hear you."

Zhao Yanling turned on the solar sensor first, and Kate turned on the mast.

If it is on the earth, because of the existence of air, this kind of solar mast is far less solid than metal, and it will inevitably be resisted by wind and can be easily broken.

But in space, where everything is a vacuum, there's no need to worry about that happening.

You can imagine that if you stand in outer space without wearing a spacesuit, stretch your fingers to saliva, and pull the spacecraft to gallop, your fingers will not feel the coolness.

But in this situation that should have been easy, Kate's face changed: "The left central mast cannot be opened in the second stage, it seems to be stuck!"

The cheers stopped abruptly, and the smile on the command center's face froze.

"No way, the Long March has come to the last step, you told me something went wrong?"

"Damn, such a simple technique, will something go wrong?"

"What age is this..."

The ground command center has various emergency measures.

Immediately, an order was issued: "Go out and check!"

Alexander's face became serious.

For now, it doesn't matter if the solar mast is extended or not.But the journey is long and always has to be started.

But the current speed of the spacecraft is very fast, going out at this time, the risk is not even the slightest bit high.A little carelessness, the astronauts will be lost in space, never to return.

Because the spacecraft has entered the orbit of Mars and cannot stop or slow down.

What is a Hohmann transfer orbit?

In simple terms, the spacecraft enters Earth orbit and then accelerates at periapsis.When sailing to the apoapsis, accelerate again and enter the orbit of Mars.Calculating the launch time can ensure that when the spacecraft enters the orbit of Mars, it happens to be on the same position line as Mars.The orbit of Mars is much larger than that of the Earth, and it will take more time to run the same angular distance.That is to say, the timing of launching the spacecraft must wait until Mars moves in front of the earth.The orbital period of the spacecraft is about 520 days.But the spacecraft only needs to travel half of this orbit to reach Mars, which is about 260 days.The orbital period of Mars is 687 days, and within 260 days of arriving at Mars, the angular distance of Mars is 136 degrees.Therefore, the best time to launch the spacecraft is when Mars is 44 degrees in front of the Earth.

That is to say, the spaceship has to go in a semicircle, and when it departs and arrives, the bow of the ship just turns around.Rather than following the shortest straight line between two points.

That's the way to save the most fuel.If the speed is reduced and then accelerated, a lot of extra fuel will be wasted, which is contrary to the original intention and may cause errors in the mission.

Alexander went to unbuckle his seat belt: "I'll go."

Zhao Yanling stopped him: "Hehe, I know you are an old guy among astronauts, but let me do it."

Alexander shook his head: "You are inexperienced, just in case..."

Zhao Yanling laughed: "It's a trivial matter, you can easily grasp it, just wait and see."

Alexander: "..."

Kate: "..."

Command Center: "Do what you can..."
