Chapter 382 It's Meteorites

Seeing the obvious expressions of distrust on the faces of the two, Zhao Yanling had no choice but to restrain his emotions, and his tone was as indifferent as possible: "I mean, if, if it is possible without consuming fuel, we can only change the course inclination, change the transfer track route, and arrive early. Does the apoapsis happen to meet Mars? Even, we don’t need to accelerate even the apoapsis, and directly use inertia to rush into the orbit of Mars?”

In fact, the current long-distance spacecraft all use the escape velocity to generate unpowered flight.

Because space is a vacuum, or infinitely close to a vacuum.The reason why Homan transfers the orbit to save fuel is not by his own continuous reaction force navigation, but by inertia.In other words, you can run without relying on anything.

Space is so amazing. If a spacesuit can provide power, or a spacesuit can enable astronauts to sleep at low temperature, astronauts can even float to Mars with the spacesuit alone.Of course, this is only in theory.

Previously, SpaceX wanted to develop a spacecraft, and it planned to use the direct hit method, simply and crudely propelled by fuel, to accelerate directly from the earth to Mars before Mars was closest to the earth.

Of course, fuel costs are sky-high.

In addition, if technology can make cryogenic hibernation possible, space travel will also become easier.After a person sleeps and wakes up, he arrives at his destination.

As Zhao Yanling said, she also took out her tablet computer, drew a circle, drew the orbits of the earth and Mars, and drew the orbit of the spaceship.

In the picture, his conception is clear at a glance.

Alexander poured cold water: "First of all, what you said is not relying on the external force of the fuel, I guess we must not be able to measure the speed. Relying on the sun to measure the speed, the equipment on our spacecraft is not accurate enough. Secondly, the yaw is too large, it would be better if we arrived early. In case If you miss Mars, do you want to chase after it? In the end, the command center will definitely not allow us to do this, it is too dangerous."

In the eyes of him and Kate, Zhao Yanling is the whimsy of a rookie astronaut.

If it's on Earth, it's okay to budget for all the acceleration.Now that such a play suddenly comes, who will do the calculations for them?

Zhao Yanling unconsciously drew circles on the screen of the tablet computer with her fingers, and said for a moment: "I remember, during the training, I was told that our spaceship has a micro-radar that can be released. Every time we run 500 to 1000 kilometers or more At a distant location, release the radar once to measure the speed using relative speed. Calculate in turn until you reach the orbit of Mars, the risk factor is not that big."

In fact, the next journey of the three of them is very idle.But if they want to proceed as Zhao Yanling said, they won't be able to relax.

In space, it is a good thing not to be idle, and doing nothing will affect your mood instead.

However, if Zhao Yanling's plan is really feasible, Kate and Alexander will be afraid.

Brother, it’s fine for you to die by yourself, let’s be bored and bear with it, I really don’t want to die with you!

Seeing the expressions on their faces, Zhao Yanling couldn't help but be embarrassed.

He just didn't want to be by Nivi's side before the second child was born.

He had no choice but to settle for the next best thing: "So if we follow the current track and increase the speed a little bit, will it have any impact?"

Alexander thought about it seriously: "That doesn't matter. Although the resistance in space is negligible, there is some. The time to reach the orbit of Mars must be set in advance. In short, we must not miss Mars orbiting to the designated position."

Hearing this, Zhao Yanling fell silent.But I have my own calculations in my heart, and I will wait to see the results!
These conversations are all stored by the camera and microphone, and sent back to the control center when an opportunity arises.

After hearing what Zhao Yanling said, the staff in the control center were blown away.

His performance when he went out to push the solar mast before made many people dissatisfied, thinking that he was too arrogant, and that this son was a model of disorganization and discipline.

Now I don't know what kind of moth I'm thinking about, so the multi-billion-dollar mission cannot be destroyed by him willfully.

Another group of people think that their worries are unfounded. In space, what else can they do except start the engine to accelerate?Are the other two astronauts eating dry food?

William sneered: "What are you afraid of? Did he go outside the spaceship and push it with his hands?"

Because the video needs to be supervised by multiple parties, the United States did not send it out, but the European side made it public.

Netizens around the world are divided into two factions and started a debate.

One group of people, most of them don't understand aerospace knowledge, they don't know what's going on.

"Old Zhao's words seem to have calmed those two."

"Is it possible?"

The other faction was full of sarcasm.

"Wonderful."

"Death by tricks!"

"Who do you think you are? Change the course by yourself?"

Then, all kinds of wars and five scumbags started to debate on the Internet.

Everyone put forward all kinds of data, and no matter what technology is available today, they all use it as an argument and express their opinions.

Zhao Yanling, who is thousands of miles away, has the ability to make waves on the Internet, making many celebrities who rack their brains to grab the headlines want to cry.

You are gone, why are you still occupying the magpie's nest!

And recently, Eva Green, who was interviewed, this gothic French beauty who once said that "no one is worthy of me", this weird and sexy world-class beauty who can seduce men and women, bluntly said that if If she was asked to choose a man, she would definitely choose Bruvenszhao.

The reporter asked her why, and Eva Green said bluntly: "Because he is sexy, versatile, versatile and has excellent physical fitness. No matter in terms of physiology or psychology, he is a man who can satisfy women."

The reporter was stunned: "How do you know that his physical fitness is superb? Could it be..."

Eva Green smiled without saying a word.

Selema, who swiped her phone to watch the news, scolded: "Bichi!"

In fact, except that her skin color is darker than Eva Green's, her face shape is a bit similar.But the edges and corners are not as hard as Eva Green, and they are fuller.

Eva Green is the beginning, and there are stars starting to rub Zhao Yanling's enthusiasm in various ways.

Zhao Yanling is not in the arena, but there is no shortage of his legends in the arena...

The legendary Zhao Yanling was on a video call with his family at this time.

"Old man, why did you fight with someone again today?"

The yellow-haired girl rolled her big eyes: "Mai said that the little old man is ugly, and I have persuaded him to change his opinion. But he didn't listen, so I had to manually let him understand that the little old man is very beautiful. And, the little old man is very beautiful. When I become a mother, my mother said that people who want to be mothers are beautiful."

Zhao Yanling was embarrassed. He once told Zhao Lingjun that a gentleman should speak first.As a result, this brat couldn't do anything with his mouth.

After reprogramming her cerebellum, Zhao Yanling hung up the video.

It was time to rest again, he pretended to sleep, but in fact he just closed his eyes.

After Kate and Alexander snored softly, he untied the rope, got out of the sleeping bag, and ran to the operating room.

He first secretly released a miniature radar, bounced his body vigorously with his legs, and pressed his hands against the inner wall in front of the spaceship.

The weight of the micro-radar is fixed, and when it is ejected and the relative speed of the spacecraft is fast enough, the speed can be calculated using Kepler's law.With the velocity, the angle to the heading track can be calculated.

As long as the distance between the spacecraft and the micro-radar does not exceed a certain range, the signals of the two parties can be connected, and the acceleration of the spacecraft can be calculated.

Zhao Yanling used "propulsion" to slowly accelerate the spacecraft.

The data on the display slowly began to change. Although the acceleration was very low, it actually increased.

This shocked Zhao Yanling's heart!But he let go.

How strong is the "advance"?
Under the gravitational force of the earth, "propelling" can't even pull him up flat, it can only play an auxiliary role.

The Mars Pioneer was a colossal thing, weighing in tons, larger than most spacecraft.

Can such a large spaceship be accelerated with a strength that cannot lift a weight of two hundred catties?

The answer is yes!

The ion electric propulsion engine is already being developed in the United States.Their acceleration may be only a few centimeters per second or even lower, and this kind of thrust can only "blow a piece of paper".But this kind of poor engine with low reaction force can accelerate a manned spacecraft to an incredible speed, and it can reach Mars in 39 days.

Because it is different from the air resistance on the earth.Space is a vacuum, and accelerations can be superimposed.

Liquid fuel is very limited, but the ion electric thruster can use solar energy to generate electricity and keep using it until it accelerates the spacecraft to a sufficient speed.

"Propulsion" is much stronger than the power of the ion propulsion engine. If Zhao Yanling wanted to, he could accelerate the spaceship until he was exhausted.By superimposing a few hours of acceleration every day, he can also get the spacecraft to Mars orbit in 40 days, or even faster.

The reason why he dared to go to space is because of two biggest confidences, one is space and the other is propulsion.

But, after all, he is not the only astronaut on the Mars Pioneer.

So, after giving the ship some speed, he stopped and went back to sleep.

However, the next day, when Kate woke up from her sleep and checked the various parameters of the spacecraft, she was in a bad mood.

"Shet!" Kate patted her head. "Look, you two, the speed of the spaceship is accelerating!"

Zhao Yanling cooperated with their performance and couldn't turn a blind eye.Moreover, his surprised expression is in line with psychological characteristics, and it disappears in a flash.

Many actors, in order to perform, will always wear a shocked expression on their faces.

In fact, anyone with a little understanding of psychology would know that his shock was fake.Because the shocked expressions of normal people usually disappear within two seconds, or even shorter, this is the real shock.If a person is in a state of shock for more than 20 or [-] seconds, you can expose his acting skills.

Alexander muttered to himself: "It's unscientific, why is this happening?"

Kate checked the fuel situation and was relieved to find that there had been no change.

She was really afraid that this was the result of Zhao Yanling turning on the engine to accelerate on his own initiative.

For them, every drop of fuel is precious, and fuel is their life.

Zhao Yanling was thoughtful: "Maybe last night, a meteorite on the same course as ours hit the spaceship, and then produced a slight acceleration. Yes, it must be caused by the meteorite. If this happens all the time, the speed If it reaches a certain level, do we have to adjust the yaw angle?"

Alexander: "..."
