Chapter 240 One Small Step, Crisis

"Bon trip."

After separation, the two astronauts who stayed on the manned spaceship can only bless.

The next task can only be completed by Zhang Kai alone.

From the small porthole of the manned spaceship spacecraft, Qian Zhubin and Li Haiyan could still see a fiery red Mars burrowing into the bottom, like a burning flame.

Visible to the naked eye, the Mars lander is shrinking, burning flames like a match.

Without communication, Qian Zhubin and Li Haiyan could only pray silently in their hearts.

On the other hand, everyone in the central control command center did not dare to breathe, as if breathing here could affect the Mars lander tens of millions of kilometers away.

Ten seconds later, the Mars lander that passed through the black barrier was connected to the spacecraft again with a signal.

Judging from the returned lander data, the lander is relatively stable.

With the brand-new gyro ceremony design, supported by the candy balance algorithm, Zhang Kai in the cabin felt the same shaking as a car driving on a cement road.

Unlike the manned spaceship, the lander does not have a porthole design.

The scene outside the lander can only be observed through a ten-inch screen.

When there were still ten kilometers from the ground, the main engine started to work.

under strong momentum.

The landing speed of the Mars lander began to decrease, and the multiple small engines that adjusted the attitude balance of the Mars vibrator sprayed flames from time to time, so that the attitude of the Mars lander was balanced.

A minute later, the Mars lander fell into a huge crater.

From the data point of view, the vertical height of the crater has reached an astonishing 600 meters.

With the main engine turned off, the lander with its brackets deployed fell to the ground under the gravity of Mars at the last half meter above the ground.

"Firefly, this is the Mars lander, I have landed safely."

First there was a sound of electric current, and after a while, the sound came.

"This is the Huowing manned spaceship. The monitoring instrument has detected that the weather in your surrounding area is good, which is very suitable for leaving the cabin. It is recommended to perform the task of leaving the cabin and soil collection after the self-inspection is completed."

"Mars lander received."

Zhang Kai, who was wearing a heavy spacesuit, sat in the driver's seat and performed a self-inspection of the Mars lander according to the manual control command panel.

This is not only related to whether the mission can be completed, but also whether he can return to space after completing all the missions.

Five minutes later, Bluestar Ground received the video sent back by the Huowing manned spaceship, and once again marveled at the power of the balance algorithm.

More than half an hour later, Blue Star was already noon.

But at this time, everyone was obviously not in the mood to eat.

Inside the crater, Zhang Kai slowly opened the hatch.

No one knew that, tens of kilometers away from the crater, a breeze blew by, forming a small vortex that was weak and windy.

Holding the ladder, Zhang Kai carefully walked down step by step.

At the last step, Zhang Kai paused.

A fragment flashed through my mind.

Zhang Kai, who could hear his own breathing, stepped heavily on the red ground.

Then Zhang Kai said to the panoramic lens on his arm:

"I'm out of the cabin, feeling fine!"

The camera turned and aimed at the ground.

"That's one small step for man, one giant leap for mankind."

At this moment, Zhang Kai felt an unprecedented sense of pride.

From now on, everything will be written into textbooks and recorded as a moment in history.

Humans land on Mars for the first time.

This firefly star was once regarded as ominous by the ancients.

Just because of the soil quality, Zhang Kai's footprints were not very deep.

Coupled with the storm on Mars, this footprint cannot be preserved for too long.

After finishing these, Zhang Kai picked up the special national flag and inserted it into the soil vigorously.

At this moment, the sound of zizzing electricity came from the headset of the space suit, as well as the intermittent voices of Qian Zhubin and Li Haiyan.

"... away from... there is... wind..."

"Magnetic field... interference..."

"..."

After several repetitions, Zhang Kai finally got a rough idea from the intermittent voice.

In an instant, Zhang Kai's hair stood on end, and his face became even paler.

storm!

A huge Martian storm is growing rapidly, and what's more, the eye of the storm is not far from the crater.

Evacuate now?

After so many years of hard work, the country has paid such a high price, isn't it all in vain.

Gritting his teeth, Zhang Kai returned to the Mars lander as quickly as possible to get the soil sampling equipment.

In the distant orbit of Mars, Qian Zhubin and Li Haiyan kept urging Zhang Kai to give up the last mission and return immediately.

I don't know what's special about the soil in this area. The soil rolled up by the storm actually forms a subtle magnetic field centered on the eye of the storm, which interferes with the transmission of electromagnetic wave signals.

Looking at the predicted trajectory of the storm calculated by the computer, Qian Zhubin and Li Haiyan clenched their fists.

Qian Zhubin and Li Haiyan couldn't imagine how the Mars lander would return under such a strong storm.

On Mars, Zhang Kai was busy sampling.

And far away in the central control command center of Blue Star, a group of scientists are discussing fiercely how to make the Mars probe return safely and dock safely with the Huowing manned spaceship.

"What if we wait for the eye of the storm to move over the crater, fire the engine and head back?"

"In the eye of the storm, it's completely unaffected by the storm."

"No, this is absolutely not possible."

"Computer forecasts of storm paths usually have large errors because there are too many influencing factors."

"Besides, who can guarantee that the Mars lander can withstand a storm."

"Once the Mars rover rolls over, our astronauts will never come back."

"Without enough food and water and oxygen, the astronauts simply cannot wait for rescue."

"The risk is too great."

Sitting in the last row, Mo Jingchun held Candy in his arms and watched the teacher spar with the Confucians.

As the chief designer, no one knows the Mars lander better than the teacher.

At this moment, Chen Xihe came over and asked Mo Jingchun with a serious face:

"Mo Jingchun, if the Mars lander takes off on the edge of a storm, can your algorithm keep the Mars lander in balance?"

Mo Jingchun froze for a moment, then quickly nodded in response:

"Theoretically, there is no problem, it's just..."

"What time is it, let's finish telling the truth once."

Mo Jingchun didn't dare to be careless, and expressed his worries.

"Teacher, you also know that the more complex the environment is, the more times the algorithm will call the attitude balance engine to ignite, and the longer the time will be."

"If the fuel is insufficient, even if the Mars lander rises to the atmosphere, it will eventually fall under the action of gravity."

"okay, I get it."

The next moment, Chen Xihe directly made a decision, requesting that the Mars lander be ignited and take off in seven minutes.

When the Mars lander was designed, possible emergencies were considered, and 20% of the fuel was reserved.
