Son of the Stars

Chapter 182 Abnormality
If we only look at it from the perspective of Dawn 7, the landing module is indeed like a slowly falling flower - but Dawn itself is the tree.

Although the robotic arm can throw the landing module out at a faster speed, this will have a huge negative impact on the attitude of Dawn 7 in orbit. The forces are mutual. If the landing module is thrown quickly like a stone, the orbital module will also be affected by the same force.

Stabilizing the attitude of the orbital module and suppressing undesirable rotation consumes much more propellant than slowly releasing the landing module. Therefore, the National Aeronautics and Space Administration set a "speed of five centimeters per second" when designing the landing module release procedure from the beginning. the maximum release speed.

After all, the size of the ship combination is too large, and the attitude change limit that the momentum wheel can adjust is this level.

It took about twenty minutes for the landing module to slowly drift away from Mars at a speed of five centimeters per second. The distance of 60 meters was enough to ensure the safety of the engine deceleration. Then two liquid rocket thrusters, not much thicker than a human arm, began to burn, and the landing module slowly left the coverage area of ​​Dawn 7.

"Finally sent off." Zheng Yan sighed as she floated by the porthole, watching the disappearing landing craft, "It's been almost half an hour."

"It's not good to release it too slowly." Ruan Hongying echoed beside Zheng Yan, "It's been floating next to the porthole. It feels like it's urging them to leave quickly."

The two female astronauts looked at each other, and then burst into hearty laughter.

For more than a year, there have been seven people in the Dawn 7 cabin. Despite the size of the cabin and the well-designed functional areas of the cabin, humans are creatures that need some solitude from time to time - companionship is important, of course, but the opportunity and space for solitude is equally significant.

It's like charging equipment with hydrogen, although everyone generally chooses to directly inject hydrogen into the pressure vessel. But the energy replenishment method of replacing the pressure vessel together is also important - only in this way can the energy company have the opportunity to check the integrity and airtightness of the pressure vessel. It is a disservice to itself and others to keep the pressure vessel installed in the vehicle without replacing it. Irresponsible.

Going without any personal space for more than a year is a very difficult and painful thing even for well-trained astronauts. Fortunately, everyone still has hope - the Mars base being designed is a single-person cabin.

Although they cannot enjoy the treatment of a single cabin on the Mars ground for the time being, Zheng Yan and Ruan Hongying can still experience the treatment of a single cabin. There are four cabins for two people, so it may be more difficult to put them together.

According to the schedule, Zheng Yan took on the duty of being on duty first. It's said to be on duty, but actually it means sitting in the living cabin and listening to the emergency radio channel in the command cabin. Since the last time she suffered from cognitive impairment, Zheng Yan herself has stopped entering the command module. Although no one said it clearly, Zheng Yan still arranged her work content based on the premise of "disability".

If she heard a sound on the emergency radio channel, she would not continue to listen or answer. Zheng Yan, who is in the living cabin, will immediately ask Ruan Hongying to listen to the frequency content to ensure that this is not her auditory hallucination or hallucination.

Arranging one's work content based on disability is very uncomfortable in itself. What's even more uncomfortable is that Zheng Yan is not even sure whether the workflow he designed is reasonable and credible. She submitted the plan to the shipboard AI, all members of Shuguang-6 and the ground monitoring team of the National Aeronautics and Space Administration. After receiving three "affirmative" replies, Zheng Yan relaxed a little.

The shadow of the landing module was almost invisible from the porthole. Only with the help and outline of the AI, Zheng Yan could see a small light spot moving - drifting towards the rear of the orbital module.

Like a brave larvae separated from its mother's body - swimming bravely but slowly towards the red ocean. "Shuguang 7, this is the Dengzhuang command center." Zheng Yan was watching the landing module slowly disappear from her sight. Suddenly she heard a call with interference and distortion coming from the command module, "Shuguang 7 , this is the Dengzhuang command center, we are sending you an emergency order."

Zheng Yan, who was slowly floating towards the cabin wall caller, paused, and then suddenly tugged on the fixed rope used to control the direction of the body's floating.

Like a real swallow, she quickly rushed to the pager.

"Hongying, come out quickly - there is a call from the command module." Zheng Yan tried her best to control her tone of voice, for fear of scaring her little sister, "The call sign says it is from the Dengzhuang Command Center. Come out and listen. "

"...the ground center station has encountered serious interference, and mass collapses have seriously weakened the center's operational capabilities." After Ruan Hongying left the cabin, the first sentence she heard was the important text part, "South America and North America. The call arrays in the region have stopped operating, and the operating efficiency of the Australian call arrays is less than 15%. The East Asia Region and the Africa Region can still maintain normal operations, but the General Administration cannot guarantee that they can continue to operate.”

The two female astronauts on Dawn 7 looked at each other and their expressions changed drastically.

"Now pass on the emergency order, the order is as follows: Shuguang 6 and Shuguang 7 will switch to autonomous mode immediately. You will independently carry out base construction and scientific research work, and decide on your own when to return - the specific decision form will be decided by you. . This notification recording will continue to be played until the Dengzhuang command center is incapacitated. I wish you good luck."

When Lu Chen was rescued from the "launch cabin", the surrounding environment looked almost like an earthquake.

There was so much dust that it looked like it had just been bombed.

Lu Chen, who had just been helped out of the launch chamber, coughed several times due to the dust. He turned his head and glanced at the "building" structure that was once the office of the academician of the Institute of Physics, only to see a twisted and unrecognizable wreckage.

Although the launch capsule took Lu Shen to escape, the landing place was a residential area full of old buildings. Several houses were torn into pieces by the recoil tail flames of the launch module, but fortunately there seemed to be no casualties.

Residents whose roofs suddenly disappeared were greeting the perpetrators with affectionate expletives. The black-clad Investigation Bureau agents who came to rescue Lu Chen not only had to guard against the dangerous factors that caused the "ultimate escape device" to be activated, but they also had to guard against ordinary people whose houses were suddenly blown to pieces by the tail flames of solid rockets.

Of course, Lu Chen had no intention of destroying other people's houses, but he couldn't help but the rocket turned into a Brownian motion bomb in the sky - this made him suddenly feel a strong sense of guilt.

It was someone else's house, someone else's home - a family living in it from birth to death. In addition to being an important place, it is also a place where memories are carried, the condensation of family affection and the soil of love...

Lu Chen suddenly felt a little dizzy.

Am I usually such a sentimental person?
