wild star

Chapter 376
There is an intuition called a woman's intuition.

Zhao Yanling's expression was as usual, she hugged her daughter and did not let go, which was rare.

But Ke Niwei always aimed at Selema.

Originally, Selema wanted to leave before Nivi and her mother came back.Washington is not far from Virginia, just a few hours drive away.

But she also missed Zhao Lingjun and Xiao Laodao a little bit, so she didn't leave.

After Zhao Lingjun was handed over to Selema, Niwei said to Zhao Yanling, "Why do I feel that something is wrong with Selema?"

Let Zhao Yanling talk, it's too embarrassing, and it's hard to tell.Moreover, he was afraid that there would be a gap between Niwei and Selema from now on, and they had watched her grow up.

Look what you've done...

Don't say it, I feel uncomfortable.

After hesitating for a moment, Niwei knew that he had something on his mind, but she didn't ask any more questions, and didn't think about it.

The next day, Selema left.

In the evening, Zhao Yanling came back, played with the car for a while with her daughter, and finished dinner.

When I was having a turmoil with Niwei, Niwei suddenly asked.

The dialogue process is indescribable!
……

Zhao Yanling's life only caused a little turmoil, and he continued to live step by step without any waves.

Time flies. After a period of intensive training, he is already a qualified astronaut. What he lacks is experience.

On this day, William approached him: "Zhao, we are going to hold a press conference tonight, you should dress more formally."

What should come will always come, Zhao Yanling is fearless, he can't wait to go back sooner.

Zhao Yanling's shirt and trousers, his leather shoes were well polished, his hair was combed back in an orderly manner, and his beard was cleanly shaved.

[-]:[-] p.m. ET sharp, Brighton Convention Centre.

NASA is still very powerful. This time they announced a major event, which attracted the attention of media from all over the world.

The conference center was full of seats, and the global simultaneous live broadcast.

The reporter had already sat down like a primary school student, and no one wanted to miss the exciting content.

Director of the Solar System Exploration Division of NASA Goddard Space Flight Center, Representative Scientist of Goddard Space Flight Center, Senior Researcher of Jet Propulsion Laboratory, Scientist of Mars Science Laboratory Project Department of Jet Propulsion Laboratory, Ministry of Industry and Information Technology of China , National Defense Science and Industry Agency, representatives of China National Space Administration, representatives of various scientific laboratories of ESA, and representatives of Russia's Ministry of Defense attended together.In addition, there are representatives of NLT.

As for the media, there are too many to describe, and you can find all kinds of skin colors here.

As astronauts, there were three people present, namely Alexander from Russia, Cat Ross from the United States, and Zhao Yanling from China.

When Zhao Yanling appeared on the stage, he also won waves of whistles.

Compared with the representatives and scientists of the national space agencies with big bellies, as well as Alexander and others, Zhao Yanling was a handsome man among the handsome men present, and he also had the names of explorers and stars.

When he stood in the crowd, he stood out from the crowd.

People in China frowned. They felt that this was a serious occasion and it was not suitable for such a show.

A clerk with an ordinary position whispered to Zhao Yanling who walked onto the stage with a straight face, "Pay attention to the influence."

Zhao Yanling smiled disdainfully: "The charm can't be stopped, you can do it if you want?"

Sometimes, he likes to travel around the world, not because of anything else, but because he can make a fool of himself and cause harm at will in other places, but he can't do it in China.

This is the territory of the Americans. I just toss about it as I like. Do you care?
Seeing his attitude, the little clerk was furious and helpless.

I saw Zhao Yanling greeted people skillfully, no matter if they were reporters or scientists, there seemed to be no one he didn't know.

The little clerk was even more helpless, what the hell, his group became outsiders instead.

"It's unbelievable, a little bit of achievement is going to the sky!" The little clerk and the higher-ranking officer next to him complained in an official tone.

"That's not a little achievement. This is the United States, it's useless for you to be modest, you might as well be more public."

Clerk: "..."

The conference begins.

The NASA spokesperson turned on the microphone and said: "Today we mainly announce one thing. On the 6th of next month, the space agency will send three astronauts into space and carry people to Mars. If possible, there may be a landing... "

Before I finished talking, the frying pan was on.

We all know that Zhao Yanling has become an astronaut and is going on a space adventure.

But no one knows that his destination is Mars.That's Mars, it's easy to get there, and it's hard to buy a return ticket...

Previously, NASA planned to send humans to Mars in five years.This plan was five years ahead of schedule, so why the sudden rush?
The speaker made a downward gesture, and the voice faded away.

He continued: "For this mission to Mars, there are astronauts represented by three parties. Europe represents Alexander, the United States represents Cat Ross, and China represents Bluwins Zhao."

Next, the speaker announced the itinerary, the model of the rocket and the model of the spacecraft.

It is taking the route of the Hohmann transfer orbit spacecraft, and the flight time is expected to be about 260 days.During this time, Mars orbits at an angular distance of about 136 degrees.Therefore, the best time to launch the spacecraft is on the 6th of next month, when Mars is 44 degrees in front of the earth.

These calculations, of course, are to save the fuel of the spacecraft.

The spacecraft did not fly to Mars at one time, but performed multi-section splicing in low-Earth orbit. Several sections have been successfully launched before.

This time, the company that spent the most money was actually NLT, and the rest was shared equally by the other three parties.However, NLT has produced so much blood, but only a few space biological research projects have been carried out, which is too weird.

The life support load of the three astronauts is very low, with an average daily consumption of 1 kg of oxygen, 2.5 kg of water, and only about 0.6 kg of caloric intake.

This is almost the minimum standard of survival, which is very draining on the morale of astronauts during long-distance space travel.But the spaceflight is too long and the time is too long, and the astronauts can bear the hunger and thirst. If there is no fuel, they will stop eating when they drift in the universe on the return journey.

After explaining the situation roughly, it was time for reporters to ask questions.

The speakers gave preference to journalists from the United States.

The reporter asked: "Excuse me, why didn't you take the direct hit orbit? Is it because there is not enough funds and too much fuel is needed?"

This question was answered by scientists from the Mars Science Laboratory Project Department of the Jet Propulsion Laboratory: "It is not a question of funding. Because this is a long-distance trip, we need to consider many things. How big is the ship? Fuel and astronauts' living load The matching ratio? On the contrary, the travel time is the last consideration. We must ensure that the astronauts can go and return smoothly, rather than considering whether they can bear the loneliness of long-distance travel.”

This bald scientist was quite humorous, and made everyone laugh with one sentence.

A British reporter asked: "Excuse me, why do four parties cooperate in this Mars mission? This has never happened before. Don't you worry about technology leaks?"

Returning to this question is the Director of the Solar System Exploration Department of Goddard Space Flight Center: "This cooperation is a rare opportunity, and it is an emergency exercise. After all, the universe is too big and the earth is too small. Maybe one day in the future we really need the earth to unite. What about tasks? But between us, each party is only responsible for one area, which is the best solution after discussion, and will not involve technology leakage.”

The Director of the Exploration Department was talking serious nonsense, but the reporter had nothing to do with him.

The Spanish reporter asked: "Excuse me, why did you choose Bluwinszhao? As far as I know, although he is an explorer, he has only been in contact with the field of astronauts for a long time, right? For such a big project, you can rest assured to let a layman play?"

The representative of the China Space Administration replied: "You are wrong. Zhao Yanling is not a layman. On the contrary, he is an excellent astronaut. His training videos have always been made public. No matter whether he is an astronaut in China or in the United States, he is the most The best of the best. We made him a part of this mission."

Zhao Yanling was surprised that it was rare in China to have such a direct and forceful spokesperson, and he liked it that way.Are you humble in front of this group of European and American journalists?Useless!
A female astronaut in Russia was even annoyed that reporters kept asking her questions about makeup and grooming.Everyone is a real technical job, you come with me?

A reporter asked Zhao Yanling: "Zhao, you have traveled so many places, why did you choose to be an astronaut in the end? Just to explore farther places? As far as I know, you have a wife and daughter. Why did you choose to go to Mars? Dangerous mission?"

Do you think I want to go?

Zhao Yanling slandered her, but she couldn't say that.He replied in a more philosophical way: "Why climb the mountain? Because the mountain is there!"

(There are world out there we can go for)

His answer won a round of applause.

A Chinese reporter asked: "Manned to Mars, the difficulty of transportation is one aspect. In addition, landing on Mars is difficult. Excuse me, before you said that if it is possible to land on Mars. Can the current technology really support human landing? After that, can you still buy a return ticket? If you land on Mars, who of the three astronauts will perform this mission?"

Mars is different from the moon. When traveling in space for a long distance, every extra catty of items you bring is a waste of money.

The escape velocity of Mars is much higher than that of the moon, and there is no air to use for combustion, so it is more difficult to manufacture thrusters.In addition, the gravitational pull of Mars is much stronger than that of the moon.In the early days, when the United States sent probes to Mars, they had to wrap the probes with elastic materials, as if a bunch of balloons were installed underneath.After the probe landed, it rebounded tens of hundreds of meters high, which shows how poor this landing technique is... The probes never return, and they stay on Mars until they die and go to bed.

A senior researcher at the Jet Propulsion Laboratory replied: "Both the spacecraft and the lander use PICA heat shields. The EDLS reentry speed of Mars is 12.5m/s. We use a parachute and reverse thrust to land. Landing is not a problem. At that time, if it is decided to Manned landing, the person who lands will be Bruvan Si Zhao."

Although the researcher avoided the question of whether he could return to space, he said that Zhao Yanling was responsible for the landing, which still caused an uproar from the reporters...
