Six days after the space station accident.

There are still five days left before the arrival of the Tianzhou-37 cargo spacecraft.

Before dawn, Lao Mao and Tang Yue got up, ready to continue preparations for the landing of the Tianzhou spacecraft, at this time the space station got in touch with the Kunlun station, and Mai Dong informed them that the hub node module was missing.

"Missing the hub pod?"

"The hub pod is gone." Mai Dong leaned on the porthole and looked out, and the spherical cabin that was originally docked with the core module had disappeared without a trace.

"The docking mechanism is broken." The old cat was very calm, pulled out two steel pipes from under the table, and touched them gently, "That thing is already fragile, and it can be considered quite tenacious until now, it is not surprising when it collapses." ”

After the collision, the hub module and the crystal module were the only two remaining modules, but no one knew how strong the connection between them was, for safety reasons, the old cat closed and locked the hatch between the crystal module and the hub module, and did not allow Mai Dong to enter the hub module.

Originally, the old cat still wanted to disconnect and simply release the hub cabin, but the docking mechanism had failed and was uncontrollable, and several attempts had no effect, so he had to give up.

By last night, the docking mechanism between the crystal module and the hub module finally collapsed, and when everyone was sleeping and resting, the hub module broke away from the United Space Station, and after Mai Dong woke up, the United Space Station was left with only the crystal module, and the hub node module may have fallen into the atmosphere at this time.

"Is the problem serious?" Tang Yue sat on the chair, took off the headphones and turned around to ask the old cat.

"Normal." The old cat was neither salty nor light, his face was expressionless, and he used the steel pipe in his hand to pestle the floor, "The hub node module will fall down sooner or later, it's just a matter of time." ”

"Girl, what about the posture of the space station? Affected? Tang Yue asked.

"I can't see it." Mai Dong replied, "The crystal capsule has been rotating slowly, and the angular velocity has not changed much. ”

"What about the orbital height?" Tang Yue asked again, "Can you give you a rough estimate of your current height?" ”

Mai Dong put up a pencil, closed one eye, and found a reference on the surface of Mars, she had learned the jumping eye method of ranging, if you go back two hundred years, she would definitely be a good artilleryman on the battlefield.

"Uh-huh......" The girl is moaning in the channel.

"How?" Tang Yue squeezed the headphone cable tightly.

"Hmmm......"

"How? How high is your current orbit? Did it fall below a hundred kilometers? ”

"Hmmm......"

"Girl?"

"Oh, Tang Yue, don't rush me, mess up all my thoughts, shut up."

Tang Yue obediently shut up.

Half a minute later, the estimate was in.

"Tang Yue, my current height is ...... Well, about one hundred and twelve kilometers. ”

"One hundred and twelve kilometers or so! The current orbital altitude of the Joint Space Station is one hundred and twelve kilometers! Old cat! When Tang Yue heard the result, he immediately took off his headphones, turned around and called out to the old cat, "Is this height safe enough?" Will you be able to make it until the arrival of the Tianzhou spacecraft? ”

The old cat squatted on the ground with his back to Tang Yue splicing the steel pipe, without looking back, raising his front paws and giving a thumbs up.

Tang Yue put on the headphones, "Girl, the old cat said that you are very safe." ”

"More than 100 kilometers are safe altitudes, the density of the atmosphere at this altitude is not enough to make the joint space station slow down significantly, the space station can maintain a relatively stable state, 80 kilometers is the alert altitude, this is the middle layer of the Martian atmosphere, once it falls to this height, the impact of atmospheric drag will rise in a straight line, the energy of the space station will be quickly consumed, 60 kilometers is the crash height, here has begun to enter the troposphere, once it falls here, it will not be saved." The old cat muttered behind Tang Yue's back, "One hundred and twelve kilometers, there's nothing to be afraid of...... There's nothing to be afraid of anymore......"

It straightened up, put the two steel pipes in front of it, and flattened them with its paws to make sure they were the same length, and the old cat was one and a half meters tall, and both steel pipes were almost as tall as it.

"What are you doing?"

"Do crutches." The old cat replied.

"Crutches?" Tang Yue didn't understand what this meant.

"Crutches." The old cat put the two steel pipes against the wall, turned around and went into the pile of debris to rummage through the foam and cardboard, "We don't know Miss Mai Dong's current physical condition, making her a pair of crutches is prepared, it can facilitate her movement after she comes down, after all, recovery also takes time...... You can't just pick her up, can you? ”

"As long as she is willing to ......," Tang Yue said, "I have no opinion." ”

"Yo, I've grown up, I'm no longer the lone wolf in the desert?" The old cat grinned and squinted, "I said that we would be single together for a lifetime, but you secretly got the certificate and found a mirror to look at your smirk." ”

Tang Yue picked up the mirror on the table and touched his cheek, a little inexplicable, "I didn't smile." ”

"The smile in his eyes is about to overflow." The old cat writhed lewkwardly in front of him again, "You are now like a spring wild cat, fidgeting, with a face full of 'Ah I'm finally no longer a person', 'Ah I'm so happy', sure enough, compared to the girl, what human civilization and what thousand years of history are scum, right?" Don't think I don't know you hid under the covers last night and laughed out loud. ”

Tang Yue was stunned and looked in the mirror again.

"Is it that obvious?"

"Humans are really vulgar." The old cat said.

"Human beings are inherently vulgar."

"I'm not against vulgarity, to be honest, on this hellish planet, compared to the happiness of you and Miss Mai Dong, what human civilization and thousands of years of history are indeed scum, there is nothing more important in this world than your life, and the pursuit of happiness has never been a vulgar thing." The old cat took out a large pile of styrofoam from the drawer, "If you can have a perfect ending, then human civilization has a perfect ending." ”

"If it weren't for the conditions, I'd be happy to see you and Miss Mai Dong have a litter of cubs, and then help you raise the cubs, give them perfect education and care, and train them to be mathematicians, physicists, chemists, biologists, historians, writers, artists...... When the cubs grow up, the cubs can continue to give birth to cubs. The old cat continued, "When you have lived a happy life together, I will bury you in the open space in front of Kunlun Station, and continue to cultivate the little cubs until I am old and out of order." ”

"Hey, you're a close relative getting married." Tang Yue reminded it that this idea was contrary to human morality, and the tone and statement of the old cat did not look like raising children, but like raising pigs.

The old cat ignored him, he stood on the floor and looked out the window with a full bosom of styrofoam, his eyes far away.

"That's my ideal cat."
