Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fus

"Originally, after fixing the problem of the rover, our research process was back on track, but recently..."

Speaking of this, Director Lin's face showed a look of helplessness.

He sighed and continued: "Our observation station has detected some messages that are not conducive to our login. "

Is there news from the observatory?"

Lu Yu asked.

Aerospace has always been a big deal! Not only do you need to work hard in industry to create enough rockets to complete the sky, but other systems also need to contribute!

It's the same over there at the observatory.

If there is no output from the observation station, then Zhurong-2 may easily encounter some difficult problems in the process of ascending to the sky!

And with the presence of observation stations, problems can be detected and solved in advance!

"Hmm!"

Director Lin nodded slightly and continued:

"Our observatory has detected that a super-large sandstorm is likely to form on Mars in the near future!" The scale should be the largest in nearly six years! "

As for the duration... I'm afraid it won't be short, at least intermittent for five months.

Speaking of this, Director Lin's face showed a look of helplessness:

"Chief Engineer Lu, you should also know how much trouble this situation will cause to our Zhurong 2 login, right?"

"Well, I know."

Lu Yu bowed his head lightly and frowned:

"The main concentration range of this sandstorm is in which specific area, can this be found?"

"I'm afraid I can't."

Director Lin shook his head and said

, "After all, Mars is so far away from the earth,

and it is already quite difficult for the comrades in our observation station to be able to detect the existence and scale of the sandstorm itself."

"It's too hard to figure out specific areas."

"It's also..."

Lu Yu thought for a moment and nodded in agreement.

It is naturally needless to say how far apart the Earth and Mars are! With such a distance and not a weather forecast, it is too difficult to find out which area this sandstorm will be concentrated in.

"Director Lin, what are your thoughts now?"

Lu Yu thought for a moment, and slowly turned his gaze to Director Lin: "Are we fighting or making peace?" "

How to deal with this problem, we must first find a suitable general direction!

The first one also depends on the decision, it must be a question of the general policy, whether to face the difficulties, or to avoid the edge for the time being?

For aerospace landing, there is no shame in avoiding the edge.

"Well..."

Director Lin's face showed a look of embarrassment:

"My initial idea was actually inclined to log in directly against it and try it."

"That's why I called Elder Zhong at that time and wanted to find you to discuss it together."

"But after all these few hours, I'm a little shaken, hahaha."

"Landing against sandstorms, if successful, it is good to say, it can be regarded as leaving a beautiful story in the history of future spaceflight." But if something happens, then our dragon country may become a joke for the whole world. Director

Lin spoke his thoughts!

If he were to be twenty years younger, and if he was a little stronger, maybe he wouldn't even hesitate!

But... Now that I am older and in a higher position, I naturally have more things to consider!

"In other words, Director Lin, you want to wait for this sandstorm to pass completely before logging in Zhurong II, right?"

"I'm afraid it won't take a short time to wait."

Lu Yu said.

Dust storms often occur on Mars, sometimes covering entire planets.

For the Mars rover....

Sandstorms will affect the density, temperature, wind speed and other parameters of the Martian atmosphere, thereby affecting the slowdown, attitude and stability of the lander!

In addition to this, the presence of dust storms can reduce visibility on the surface of Mars and interfere with image transmission and navigation systems!

It can be said that without the existence of Martian dust storms, the difficulty of official login of Mars vehicles may be far reduced by more than 40%! This is also an inevitable problem in the Mars landing project!

Ordinary sandstorms have such a great impact on the Mars rover, not to mention the largest sandstorm in the past six years!

It is no wonder that Director Lin will retreat.

"The biggest question now is how long this sandstorm will last."

Lu Yu thought for a while, and said seriously:

"If the sandstorm does not last long, it will only be five months.... Then wait, we can afford to wait.

"But what if it's more than five months?"

"The landing project of Zhurong No. 2, but the set goal on our aviation white paper this year, if it continues to be delayed, I am afraid it will still be difficult to explain at the top."

"In other words, Chief Engineer Lu, you are still more supportive of facing difficulties?"

Director Lin's face showed a clear smile:

"I know, hahaha." Young people, just have momentum!

"How long this sandstorm will last, in fact, the observatory has not yet reached an accurate conclusion." And... Five months is indeed too long.

"Maybe we really should give it a go?"

The expression on his face gradually became embarrassed again!

Before Lu Yu's figure appeared in the office, in fact, Director Lin's idea had always been "jumping left and right"!

On the one hand, he doesn't want to drag it out too long! The longer the night lasts, the longer the launch drags on, the more accidents may occur.

On the other hand, the launch of such a large-scale sandstorm will inevitably have a non-negligible impact on the work of the Mars rover!

It's like two glasses of poisoned wine!

No matter which cup it is, drinking it will not feel good!

"Director Lin, I'll tell the truth."

Lu Yu also didn't like to bend around, so he said directly: "If it follows my ideas, then no matter what, I think we should try it first!"

"If it succeeds, of course it is the best!"

"If we can't improve the anti-jamming capability of the Mars rover before launch, there is no way to make it run normally in a dust storm... It's too late to delay the launch for a while! Lu

Yu also directly said his thoughts!

In his opinion, it is no problem for Director Lin's idea to be cautious, after all, he sat in some positions, and it is necessary to consider the problem more comprehensively!

However, try it, Lu Yu thinks it is just as feasible.

"But now the problem is... If you want to improve the information anti-interference ability of the Mars rover in a short period of time, I am afraid it is somewhat unrealistic. "

If you can't make it really elevate.... Then the resources we put into it, if we don't get it right, will be wasted. The most troublesome thing is that if you apply for a temporary suspension of the launch in advance, there are many processes that need to be followed.

"When the experiment fails, go through those processes."

"I'm afraid it's too late."

Director Lin also said the points of his concerns!

"In this case, let's temporarily build a most basic model to reduce the input cost."

"Just test the waters."

"If it works, it must be the best. Unsuccessful... There is no loss, Director Lin, what do you think?

Lu Yu asked with a smile.

"You mean, we're not officially modding, just building a general model to try."

"It's not impossible."

"Relatively speaking, this delay can also be a little less, and if it fails, it should also leave us enough time to apply for the suspension of the launch."

Director Lin thought about it for a while and felt that the idea proposed by Lu Yu was really a little feasible.

Compared with direct improvement, just building a preliminary model can undoubtedly greatly reduce the investment and cost, and there is a lot of time available.

If it fails, there should be time to properly submit the application to abort the launch!

Of course... Compared to direct hands-on improvement, building only one preliminary model has the same negative impact!

If the model runs successfully, then you need to look at the extra investment time to bring the model to life!

More importantly, although some technologies can operate normally in the simulation experiments of the preliminary model, the effect is greatly reduced in the real "actual combat"!

To put it bluntly, it's a gamble!

"Okay."

"Let's try it first, if I give up like this, I actually have some overwhelmed in my heart."

Director Lin showed a wry smile on his face and nodded.

"Hmm."

"In fact, the problem of sandstorms has always been a hurdle in the big project of Mars landing."

"After all, the sandstorm there is quite different from the sandstorm in our conventional sense."

"It rolls up dust and sand, and the electromagnetic interference it brings is like an extra layer of enchantment out of thin air for our Mars rover."

Lu Yu pondered:

"So, the first problem we have to solve is to determine the specific technical direction first!"

"Well, the hero sees the same thing!"

Director Lin's eyes showed a satisfied smile, he and Lu Yu's thoughts coincided!

The difficulty now is that the lander cannot receive control signals from Earth in real time in the Martian atmosphere.

It's like a remote-controlled car.

If the signal sensing between the remote control car and the controller is blocked, then even if the battery in the remote control can still continue to work, it is just a piece of scrap iron!

Only if the remote control can be used, it is a remote control car!

Under normal circumstances, the Mars rover needs to be guided by the command base on Blue Star during the landing process.

But because of this sandstorm... The process of guidance will inevitably not be so smooth!

"Director Lin, I'm thinking..." "

Can we rely on the autonomous navigation system to complete the landing?"

"Since conventional guidance means can't do it, can we build an autonomous navigation system ourselves?"

After thinking for a short time, Lu Yu directly proposed his conjecture to Director Lin!

Since conventional means of guidance do not work... Can an autonomous navigation system help the Mars rover successfully complete the landing?

"The problem of autonomous navigation systems, I also thought about it."

"It's actually a conventional traditional way to avoid the effects of sandstorms."

"With an autonomous navigation system, after landing, the Mars rover can re-determine its position and orientation based on its own sensors and instruments, and establish contact with the orbiter or Earth."

"But..."

Director Lin's face showed a look of embarrassment:

"The scale and intensity of the sandstorm we encountered this time are the largest in recent years. Its impact is far beyond conventional sandstorms. "

Even if an autonomous navigation system is loaded, it may still be interfered or malfunctioned by a dust storm, causing the lander to deviate from its intended orbit and land in an unknown area..."

he repeated his concerns.

Loading an autonomous navigation system, this is not a novel method in the aerospace world!

Director Lin had naturally considered this issue before!

However, in his opinion, in the face of such a large-scale sandstorm, this path may not work!

"No, no, no, Director Lin."

Lu Yu shook his head!

"Conventional autonomous navigation systems may be vulnerable to large-scale dust storms, which can lead to dysfunction."

"But our Mars rover uses solar panels on memory metal!"

"You should know what I mean, right?"

"What does this have to do with the solar panels on memory metal.... You mean, energy!

Director Lin's voice suddenly shook, and the whole person reacted instantly, and there was a touch of clarity in his eyes!

"That's right, energy!"

Lu Yu also smiled!

It is worthy of Director Lin, he mentioned it so lightly, and directly grasped the key point of the problem!

Ordinary people definitely don't have this ability!

"We use a solar panel base made of memory metal, which means that our Mars rover has greater energy stability!"

"Compared to other Mars rovers that have landed on Mars."

"The more power we can use, the more autonomous navigation communication systems we can build!"

Lu Yu took a step forward, took out a black pen, and wrote on the whiteboard:

"Director Lin, look."

"After carrying an autonomous navigation system, our Mars rover can use its own solar panels or other energy equipment to provide itself with enough power.

"Under the condition of maintaining the operating state and communication ability, if you encounter bad weather such as sandstorms, you can enter sleep mode and wait for the weather to improve before returning to work..."

Lu Yu wrote and drew on the whiteboard, roughly explaining his ideas to Director Lin.

Although he did not use specific modeling methods to express his ideas, but in doing so, Director Lin was enough to understand what he meant!

"Your thoughts.... There is indeed a great deal of feasibility.

"However, how to carry the autonomous communication system and how to use the advantages of high power."

"Do you have an idea for this most critical question?"

Director Lin asked slowly after taking a deep breath.
