Chapter 180 Moving Towards Mars (please subscribe, thank you)

Countless people are longing for the pursuit of the universe, but technology is always a big problem.

"It's not difficult to make a rocket. It's not difficult even to fly to Mars, but what about it? Even if it really flies over, there is still no way to land."

Scientists through the study of the universe believe that in the vast universe, as long as a planet has the same natural environment and conditions as the earth, there may be life, and the people on earth should not be the lonely people in the universe. To this end, scientists have conducted a lot of observations and discovered that the Earth's nearest neighbor-Mars is likely to be a planet where life is hidden. Everyone knows that the existence of life requires three conditions: sunlight, air and water. The environment of Mars is similar to that of the earth:

First, its average distance from the sun is 1.524 astronomical units, which is slightly farther than the distance between the earth and the sun. At the same time, it has a hard solid surface and a seasonal and geological climate change cycle.

Secondly, there is a dry riverbed formed by running water on its surface, which indicates that there may have been liquid water here in ancient times. Scientists have discovered through investigations that the environmental conditions of Mars are similar to that of Antarctica on Earth, especially in the polar regions of Mars. The changes in the polar caps indicate that not only water exists there, but the temperature in summer will reach 0°C or higher. The white lichens that grow in the cold Antarctica are similar to green algae.

Moreover, although the air on Mars is thin and more than 95% of the atmosphere is suffocating carbon dioxide, there is still a small amount of oxygen.

So, are there any living things on Mars? This is the biggest outstanding case in a century. Scientists from the United States Space Agency have disclosed that simple petrified bacteria were found in a Martian meteorite that fell on Earth 13,000 years ago, proving that there is indeed life on Mars.

In the classroom, several students are studying each other.

"Regarding the Mars project, I need to know your suggestions."

Everyone looked at each other.

"Teacher, I think the Mars project is a waste of time. Not to mention the environment, the unknown of the universe is difficult for us to deal with."

Everyone nodded one after another.

In fact, this is the core of the difficulty.

Mars is very similar to the Earth. Some people even say that there is life on Mars, but Chen Fan really doesn't have much interest in these things. It is unknown. Chen Fan is not interested, it is too far away.

But many people still want to go to Mars.

"Teacher, you don't really want to send someone to Mars, do you?"

Chen Fan nodded and said: "If there is no accident, it is indeed to send someone away, who to give away, they choose by themselves, I am not responsible, but how fast is a question, I think, if it can arrive within a week, that would be the best. Yes, the fuel is sufficient now."

Will you arrive in a week?

The fastest speed of current technology is seven months.

Chen Fan wants to complete the blueprint production, then the completion of this aerial city needs a lot of people to help, Chen Fan himself can't complete it.

In fact, Chen Fan also understands that this system has started to affect himself since now, and is biased towards command.

In the later stages of academic development, many of them are not normally dealing with problems by themselves, but relying on people to deal with them.

What I need to make is the general direction.

Chen Fan gave a design drawing and said: "The fuel is absolutely sufficient, so now is the protection and training of personnel."

"Ah, teacher, can I really go?"

"The theory is ok. I can think of a probability that I can't go up, that is, being hit and the meteorite hits directly. Apart from this, there is nothing else."

Before you know it, can you go to Mars? 》

Everyone is still a little uncomfortable.

Time is spent day by day.

"The rocket attitude control system measures the attitude angle and angular rate of the rocket around its center of mass by measuring instruments, and sends out attitude control signals after processing by the intermediate device to control the rocket's flight attitude so that its actual flight pitch angle is consistent with the program flight position. The difference between the required program pitch angles is close to zero 0... keep the rocket flying along the predetermined orbit; make the rocket's flight yaw angle swing around 0, keep the rocket flying in the predetermined orbital plane, control the rocket's roll Turn the angle so that its value is also close to 0. So as to ensure the stable flight of the rocket.

Satellite attitude control is divided into passive attitude control and active attitude control. Passive attitude control is a method that uses the dynamic characteristics of the satellite itself and the environmental moment to achieve attitude stability. Passive attitude control methods include spin stability and gravity gradient stability. Active attitude control is a way to form a control command based on the attitude error (the difference between the measured value and the nominal value) and generate a control torque to achieve attitude control. "

Chen Fan stood on the side of the console.

Talking with very flat people.

"Currently the stability and performance have reached the best."

Chen Fan nodded.

A sixteen-year-old boy stood in front of a group of adults.

He was still the commander, and everyone didn't get used to it at first.

Chen Fan continued: "If you can, I hope everyone trains more trainers. I don't want to have an accident."

"Already in training."

Chen Fan nodded.

"I have a set of armor, and I will put them on, suppose, I mean, suppose, they really have an accident, the first time, you can choose to fall asleep, Xiaomei will send them back, can save them, I am not sure ."

this.

Did Chen Fan do so much preparation?

"Chen Fan, is this the reason you hate sending people to Mars?"

"Yes, I hate it, I hate it, and my classmate, Wang Hu, I have to protect it."

Everyone sighed helplessly, but they all understood that this is something that must be experienced.
