Following.

Tang Yue Lao Mao and Mai Dong spent more than ten hours to adjust the Orion spacecraft's cabins, thanks to the advanced design of the United Space Station, most of the modules are using standard interfaces, whether it is a mechanical docking mechanism or a power and control system, it can be plug and play like a USB flash drive.

In addition to making a lot of money, the bureaucrats of the Mars Project Preparation Executive Committee have done something practical.

"Alpha, Alpha attention!" The old cat stepped on the chair with one foot, grabbed the headset with his left paw, and held a pen in his right paw, giving orders, like an operational commander.

"The old ISS has been retired." Tang Yue said lazily, "Old cat, are you calling the International Space Station in Heaven?" ”

"The Alpha Class is ready." Mai Dong replied, "The docking mechanism is normal, the computer self-test is normal, the power system is normal, the control system is normal, and the circulation system is normal." ”

"Beta, Beta attention!"

"The beta is ready." Mai Dong is very capable.

"Gamma attention."

"Gamma cabin ready."

The modules of the Orion-2 spacecraft were dismantled one by one according to the planned steps, the super arm moved them to the new counterpart, and Mai Dong wore a heavy spacesuit to assist the old cat outside the cabin, working out of the capsule for two hours at a time, and then returning to the space station to rest and replace batteries and gas cylinders.

"Axial speed 0.35, repeat, axial speed 0.35! Mr. Cat, pay attention to deceleration, the radial deviation distance is 0.22 meters, repeat, the radial deviation is 0.22 meters. ”

“OK！ Roger that. ”

The old cat controls the super arm to reduce its speed.

"The capture lock is fine, the butt lock is fine, the brake is fine! The damper is normal! Tang Yue was wearing headphones, and his speech was fast and crackling, "The constant error of the three-axis attitude angle measurement is normal. ”

"Mai Dong pay attention, the remaining battery power is 27 percent, Mai Dong pay attention, your life support system battery has 27 percent remaining power, ready to connect to the backup battery." Tang Yue had three monitors in front of him at the same time, his spirit was highly tense, the old cat was the commander-in-chief, Mai Dong was carrying out extravehicular operations, and he was responsible for monitoring the overall situation, "The carbon dioxide concentration has increased by 0.3 percent, and the water vapor concentration has increased by 0.9 percent, Mai Dong, you are sweating profusely." ”

"Roger, I do sweat because I'm a little tired."

"How much water is left in the water bag?"

"And half there." Mai Dong draws fresh water from the drinking bag through a straw to replenish water, "enough is enough." ”

The huge β service module is gradually approaching the Hope experimental module, the former is a huge cylinder with a diameter of more than four meters, a rigid shell of composite materials, on the Orion spacecraft it is the living place of the crew, the Orion series of spacecraft has a life support system similar to the space station, the activity space is quite sufficient, and there is even a small chess and card room on the spacecraft, where you can play mahjong.

The α, β and γ modules disassembled by the old cat are all service modules, and after they dock with the joint space station, their own life support systems can be used as backups for the space station.

Mai Dong fastened himself to the bulkhead of the service cabin with his seat belt and moved with the No. β cabin, not far ahead of which was the Hope cabin, and the docking mechanism was ready.

The outer wall of the service cabin No. β was printed with the huge blue English letters: "PEACE", just under Mai Dong's body, and the girl saw it as soon as she looked down.

It turned out that this compartment had a name, and its original name was Mir.

If you think about it, whether it's the Martian space station or the Orion spacecraft, each module actually carries the good expectations of the namers, they call these modules Hope, call it Mir, and then send them into space with rockets to send them to Mars...... Human beings send the most beautiful things in the world to a strange world 100 million kilometers away, hoping that they can break away from the quagmire of reality and take root and grow on another planet.

That's probably what I've been sticking to so far.

Mai Dong thought silently.

The Mir module collided with the Hope module, and there was a slight shock.

"The No. β capsule was successfully captured, the capture lock was normal, and the docking lock was normal! Make a mechanical connection! Tang Yue followed closely with the report, "The power system is turned on, and the computer self-test is normal!" ”

"No problem." Mai Dong observed at the scene.

She tugged at the cable outside the cabin, climbing forward step by step, and with each step, Mai Dong had to take off the buckle of the safety rope and lock it on the bulkhead in front of her.

Extravehicular activities are still quite physically demanding, and although weight is no longer a burden in weightlessness, zero gravity can bring many other problems, such as not being able to control one's body, and tools are always floating in unexpected places.

Gravity brings stability, a chair is placed on the ground, you don't push it and it doesn't move, but in weightlessness, this natural stability is gone, Mai Dong is moving all the time, and most of her physical strength is trying to maintain her stability and balance.

The docking of the β module was successful, and the joint space station was lengthened a little more, and from now on, the Hope experimental module will no longer be the boundary of the space station, and the volume of the Mir module will be larger than that of the Hope module, and Mai Dong can roll and roll around in it.

Next, the old cat docked γ service module, which was actually the Soyuz service module, with the discovery module, and with a click, the total internal volume of the United Space Station was expanded by a third.

"OK, OK, the plan went very well." The old cat slapped his face, "Miss Mai Dong, you did a good job." ”

At this point, the three main service modules on the Orion 2 spacecraft have been dismantled, the modification of the Joint Space Station has been officially completed, and the remaining four inflatable modules will not dock with the space station, they will be strapped to the Eagle lander as buffer airbags, and this will be the third step of the work.

Everything is going according to plan.

"The flight control program has been modified, and this broken computer has died seven times, and the mission has finally been completed." The old cat patted the chassis of the workstation.

Tang Yue sat on the side, casting a sympathetic look at the hard-working computer.

The old cat is a landlord who exploits the toiling masses.

"Then we can do a simulation test, which is the most important level before landing, and we want to check for the first time if this method is really feasible."

"Mock test?" Tang Yue asked, "Is it the same as when we were on the ground?" ”

Jiuquan is one of the training centers of the Mars program, with a one-to-one size Orion spacecraft and a full set of simulation facilities for the United Space Station, covering an extremely large area, Tang Yue and they wore heavy extravehicular suits to float in the pool, opening and closing the hatch over and over again.

Ground training is a must for any space program, and different people are trained in different subjects.

Commanders like Lao Wang Lao Tang are professional astronauts, with the most subjects and the heaviest, but most of these people are veterans, and they are not the first time to go to the sky, so they are familiar with it.

"Yes." The old cat nodded, "In addition to not letting Orion really enter the atmosphere, we have to completely simulate the entire landing process, from the control of the engine, to the stability of the attitude, to the state of landing, from beginning to end, to find problems and solve them in time, and formulate emergency plans." ”

"You're going to be tired again." Tang Yue sighed.

The old cat was stunned, "It's okay, I'm not tired." ”

"No, I'm not talking about you, lord landlord...... I'm talking to it. Tang Yue pointed to the chassis of the HP workstation, "Master Cat, why are you embarrassed to say that you are not tired with a shy old face?" ”

The old cat waved a pen and paper and put on headphones, "Come on, come on!" All of them! Everyone is in working mode, and we're going to start landing for the first time! Let Orion enter the atmosphere and see how long it lasts! ”

"First mock test."

"Abbreviated as a model!"
