May 25th.

Li Sheng stared expressionlessly at the deep darkness outside the porthole, silently bearing the acceleration coming from the seat.

Now he is the co-captain of the Raymond spacecraft, flying into space, to advance the space station to be exact.

Since the end of February, Endain has been in space for up to three months of unmanned rotation tests, and has been restarted several times, fully verifying the reliability of the gravity system.

For the sake of safety, this time the mission is still 26 original crew, who are already in a sense professional crew members of the giant space station, and the roles they have played in similar missions are very different from those played in previous similar missions.

Due to the excessive number of launch missions some time ago, several launch sites temporarily do not have the ability to launch large space shuttles, this mission also needs to be Tengyun and three H1 to participate, namely Lightning, Unity and Progress, two space planes to send all astronauts up, the rest are to transport materials and equipment.

The three aerospace planes Ruiyun, Liuyun, and Tengyun are the hearts and minds of the Aviation Development Commission and the military, and they are reluctant to idle for a moment, so they all launch the remaining three H1s as common round-trip vehicles for the Advance.

The solution to this problem will have to wait for the future retrofit plan of the Advance, which will stop the rotation of the central module of the space station with an extremely strong and well-sealed super-large electromagnetic bearing ring, but that will be a long time later.

The potential of the advance to be filled with materials is terrible, and the theoretical maximum full-load operating mass can reach more than 3,800 tons, that is, there is a full 2,100 tons of load redundancy.

And the content of the tasks has remained the same, but the style has changed dramatically, and it is more radical than before, as if you want to make them mature quickly, and then they will be busy with some task.

The missions of the three H1s were completed three days ago, and Li Sheng was already faintly able to see the outlines of the Unity and Progress.

For the first crew of the Advance, they were completely oblivious to these troubles, and in this day and age, the Advance represented the forefront of technology and scale.

"Captain, what are you thinking?"

Lian Xinwei is the only doctor of psychology, who also served as a psychiatrist on the space station, and was also the pilot of this mission Ruiyun.

In the future, it will be more troublesome to get on the H2, for example, the Pioneer and the Glory can dock together, but not if it is the Storm, because the center of gravity and weight of the Storm are different from the regular version, it will cause a lot of trouble to the trim system and consume too much fuel.

I heard that there is a new generation of NPU computing units in the materials brought this time, and I hope that I can provide you with better services. ”

Of course, it is normal for these head figures to disappear for a few days, but the strange thing is that their tasks have also been adjusted to a great extent, as the astronauts who should be the most concerned in the recent stage, Lin Ju and Zhong Cheng should have appeared.

"Captain: Rear Admiral Li Sheng, the life housekeeper 'Wenxin' of No. 2101 greets you, long time no see.

Since the Aviation Development Commission decided to change the residency system of the "Advance", other people's address to Li Sheng has gradually changed to "captain", and he himself has expressed a tacit attitude.

Regardless of the psychological problems of astronauts, the limits of Advance are enough for it to complete the exploration of eight planetary systems, and it is definitely a truly epoch-making product in the history of astronautics.

The soft female voice synthesized by the robot came out of the encrypted channel, which made Li Sheng smile a little.

As if in 1906 he served as a sailor on the battleship 'Dreadnought', it may have had all sorts of flaws and maladaptations, but in general it was already the best option for its time.

But this kind of doubt was only suppressed in his heart, after all, judging from the current situation, as long as his side is steady and steady, it is impossible to face any threat.

But in addition to this, Li Sheng thought more.

According to the instructions Li Sheng received from Shen Zuozhou before his departure, at least 8 to 10 of the 26 crew members must participate in the "long-term mission" this time, and they can hold on for as long as they can without returning to Earth, and they need to test the maximum time to ensure their ability to work normally.

Now only he and the young psychiatrist were the calmest of all, even if they couldn't hold back their excitement, but they already knew in advance how things would change in the next few months.

He was keenly aware that Li Sheng was thinking about other things, but his intuition made him not continue to ask.

Of course, psychological problems are the real big problem, and the sailors on the ocean-going ships in the Age of Discovery can't stand the loneliness of jumping into the sea to commit suicide, and living away from human beings for more than a billion kilometers for several years can be imagined as a test of the astronauts' will.

The fuel storage limit of the Advance is based on the 72 hours of operation of the six A100s at full power, plus 20% redundancy, a full 1,000 tons of fuel is required, and the actual limit storage capacity reaches about 16,000 cubic meters of liquid hydrogen, about 1,130 tons of fuel, and most of the solvents in the six service cabins are used to store liquid hydrogen.

In fact, what Li Sheng is thinking about is that the Aviation Development Commission and the Space Agency are somewhat unusual in the past few days, Zhong Cheng and several core figures are not there, and Lin Ju has also disappeared.

He returned his full attention to the mission, and by this time a semicircular creation of no small or small could be seen in the porthole of the Ruiyun, which was the Advance, which was mostly illuminated by sunlight.

And the task of Endeavor is very heavy, just like the foursome who have been on the moon for half a year, this group of A0 astronauts may have to stay for the same amount of time or even longer.

The Bliksamas can only transport cargo and will have to return to Earth after replenishing supplies, while Unity and Progress are docked on both sides of the station's functional module to ensure that the center of gravity remains roughly unchanged while serving as emergency vehicles.

This is also the disadvantage of the current space station structure, in addition to its own components, if the docking of other spacecraft must be considered when rotating, it must be considered trim, it must be placed symmetrically, and the mass error can not be too large.

Three months ago, the Isaac Newton was a flash in the pan, and Aramco only conducted two subsequent tests that lasted no more than 20 days, because the Gravity Dragon, which was based on the Dragon spacecraft, was so small.

In the past three months, Endeavour has consumed little other than electricity and RCS fuel, and electricity is almost infinite for it, so the astronauts don't need much preparation to be stationed again.

Even if the number of people is increased to 50 and the material consumption is increased to 15 kilograms, it will be 30 months.

It's not just about getting acquainted with the full potential of the space station, it's about verifying how long humans can survive in space in gravity.

Lian Xinwei's voice woke him up from his thoughts, but Li Sheng just shook his head slightly:

"Nothing."

Excluding 300 tons of other types of consumables, this also means that nearly 700 tons of material storage can last for 90 months, or seven and a half years, based on the consumption of 10 kilograms of oxygen, water, food and other rations per astronaut per day.

It seems that even the ground has recognized the title of "captain", and has actually changed the settings for the robot.

"Thank you for your concern, I'll get you a replacement as soon as possible."
