Tech overlords start with a baby

Chapter 240 A small step, crisis

"Safe journey."

After the separation, the two astronauts left behind on the manned spacecraft can only wish.

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

From the small porthole of the manned spaceship, 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 getting smaller, burning flames like a match.

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

On the other hand, the people in the central control and command center are also afraid to breathe, as if breathing here can affect the Mars lander tens of millions of kilometers away.

After more than ten seconds, the Mars lander that passed through the black barrier connected to the spacecraft again.

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

With the new gyro ceremony design, with the support of the candy balance algorithm, the shaking felt by Zhang Kai in the cabin is similar to that of a car driving on a concrete road.

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

For the scene outside the lander, it can only be observed through a screen that is only ten inches in size.

When there are still ten kilometers from the ground, the main engine starts to work.

under strong power.

The landing speed of the Mars lander began to decrease, and the multiple small engines that adjusted the balance of the Mars vibrator's attitude sprayed flames from time to time, so that the Mars lander's attitude 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, in the last half meter above the ground, the lander with its stents deployed fell to the ground under the action of Mars' gravity.

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

First there was a sound of electricity, and after a while, there was a sound.

"This is the Huoying manned spacecraft. The monitoring instruments have detected that the weather in your surrounding area is good, which is very suitable for exiting the cabin. It is recommended to perform the mission of exiting the cabin and soil collection after the self-check is completed."

"Mars lander received."

Zhang Kai, wearing a heavy space suit, sat in the driver's seat and conducted a self-inspection on the Mars lander according to the manual control panel.

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

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, it was noon on Blue Star.

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 dozens of kilometers away from the crater, a gust of breeze blew past, forming a small whirlpool that could not help but be windy.

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

At the last step, Zhang Kai stopped.

A fragment flashed through my mind.

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

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

"I'm out of the cabin and feel good!"

Turn the camera around and aim 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.

After this, it will all be written into textbooks and recorded in 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 are not very deep.

Combined with the storms on Mars, the footprint doesn't last long.

After doing this, Zhang Kai picked up the specially made national flag and inserted it into the soil.

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

"...from...with...wind..."

"Magnetic field... interference..."

"..."

After several repetitions, Zhang Kai finally heard a general idea from the intermittent voice.

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

storm!

A huge Martian storm is growing fast, and what's worse, the eye isn't that far from the crater.

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

As soon as he gritted his teeth, Zhang Kai returned to the Mars lander at the fastest speed and took the soil sampling equipment.

In the far-earth 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 is special about the soil in this area. The soil rolled up by the storm has formed a delicate magnetic field centered on the eye of the wind, which interferes with the transmission of electromagnetic wave signals.

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

Qian Zhubin and Li Haiyan could not 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 talking fiercely about how to make the Mars probe return safely and safely dock with the Huoying manned spacecraft.

"What if we fire the engine back while the eye of the storm moves over the crater?"

"In the eye of the wind, there is absolutely no impact from the storm."

"No, absolutely not."

"Computer predictions of storm paths are often quite inaccurate because there are so many 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 can't wait for rescue."

"The risk is too great."

Mo Jingchun, who was sitting in the last row, held the candy in his arms and watched the teacher fight against the Confucian scholars.

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 expression:
"Mo Jingchun, if the Mars lander takes off at the edge of the storm, can your algorithm keep the Mars lander balanced?"

Mo Jingchun was stunned for a moment, then nodded quickly and replied:
"Theoretically, there is no problem, it's just..."

"It's time to tell the truth."

Mo Jingchun didn't dare to be sloppy and expressed his concerns.

"Teacher, you also know that the more complex the environment, the more times the algorithm invokes the attitude balance engine to ignite, and the longer it takes."

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

"okay, I get it."

The next moment, Chen Xihe directly made a decision and asked the Mars lander to ignite and take off in 7 minutes.

When the Mars lander was designed, taking into account possible emergencies, 20% of the fuel was reserved.
