Captain Meng Haiyang woke up from the dormant cabin.
"Captain, good morning." Sha Yuekong smiled and floated.
The two quickly finished washing and then came to the main control cabin.
Mao Chuangxin, who was on duty, saw the two of them and yawned: "Ha...good morning."
"Innovation, go and rest!" Meng Haiyang patted him on the shoulder.
"Then it's up to you. By the way, the Earth Headquarters sent a notice two hours ago. In three days, the next batch of astronauts will be launched to change shifts." Mao Chuangxin said as he floated towards the living module.
"Yeah." Meng Haiyang nodded.
Sha Yuekong, on the other hand, checked the work log of nearly eight hours.
At this time, the Homo sapiens space station is unprecedentedly large in scale.
The 133,200 tons of supplies, plus the 5,600 tons previously owned by the space station itself, increased the weight of the entire space station to 138,800 tons.
37 Spark spacecraft combine to form a huge "Ferris wheel" space station.
The length of the Tinder is 50 meters and the diameter is 10 meters. After the four Tinders are docked together, they can form a long arm with a length of 200 meters.
The 4 sets of long arms are connected to the middle universal connector of another central axis (also composed of 4 Fireships docked front and back).
This forms a central axis inserted in the center of a "ten", and two fire ships are connected to the four outer end points of the "ten", forming a "T" shape.
This used up 28 Tinder ships.
The remaining nine fire ships carried a large number of ring-shaped parts. After these parts were assembled, they formed two concentric rings, one large and one small, on the "X".
Their old space station was connected to the top of the central axis.
After checking the work log, Sha Yuegong said: "Captain, everything is normal."
"You stay in the control cabin, and I'll go to the outer ring area."
"be safe."
"rest assured!"
Meng Haiyang floated to Huzhong Cabin No. 12 below.
After opening the negative pressure gate, he stood on the electric trolley, turned the acceleration switch, and the trolley immediately moved forward along the guide rails of the cabin wall.
After passing through negative pressure gates and a distance of 300 meters, Meng Haiyang finally arrived at the outer ring area of the space station.
He fixed the electric scooter and then picked up the intercom: "Sha Yue Gong, start the rotation system."
Sha Yuegong's voice came from his earphones: "Okay, pay attention to safety!"
The eight Fire cabins in the outer ring area began to activate the auxiliary electric fuel injection thrusters, and the entire space station began to slowly rotate.
The speed was not very fast at first, but the specific impulse of the EFI thruster was too high, and after 20 minutes of continuous acceleration.
Meng Haiyang already felt that his body was very heavy.
This is when the centrifugal force generated during the rotation of the space station begins to take effect. Inside the cabin in the outer ring area, the pseudo-gravity at this time reaches about 1G, which is almost the same as the Earth's gravity coefficient.
And since the radius of the space station reaches 200 meters, the difference in centrifugal force gradient in the outer ring area is not obvious.
However, Meng Haiyang's specialized detector could clearly see the centrifugal force gradient difference data. At the same time, he checked the centrifugal force gradient in other areas of the space station.
It can be seen from the data that the closer to the central axis, the greater the difference in centrifugal force gradient, and the more serious the adverse effects on the body.
"Captain, how is the situation?"
Meng Haiyang pressed the call button: "It's okay, just a little bit heavy-footed, but this down-to-earth feeling is really missed!"
"That's good, let me know immediately if anything happens."
The rotating system was tested for more than seven hours, during which Meng Haiyang tried various tests, including eating and bathing in the outer ring area and simulating sleeping. The effect of simulating gravity was acceptable.
However, you can still clearly feel some differences from true gravity.
At this time, the other two astronauts on the space station also woke up from their hibernation capsules.
After Zhang Gongyu and David woke up, they quickly finished washing.
On the way to the control cabin, Zhang Gongyu felt that the space station was slowly rotating. Although it did not seem obvious, he still felt the weak centrifugal force of rotation.
Come to the control cabin.
"Doctor! David! Good afternoon." Sha Yuegong and the two of them nodded.
"How is the test situation of the rotation system?" Zhang Gongyu asked curiously.
Sha Yuegong smiled and replied: "The pseudo-gravity in the outer ring area is okay, barely usable, and the captain is in the outer ring area."
After a while.
Meng Haiyang also returned to the central axis area from the outer ring area.
As soon as he floated up, he rubbed his temples and said, "Hufu... It feels so uncomfortable in the rotating arm area, especially the few dozen meters near the central axis area."
"It seems that there is a lot of trouble in the rotating arm area!" Zhang Gongyu said while immersed in recording the incident in his work log.
Meng Haiyang shook his head helplessly: "And the length of the rotating arm is not enough. If the radius can be reached to 500 meters, the gradient difference of the centrifugal force will be so small that it cannot be felt."
"500 meters? We won't be able to enjoy it anymore. We probably have to wait for the next batch of astronauts to come over for testing." Zhang Gongyu replied with a smile.
Sha Yuegong added: "The next batch of astronauts will arrive at the space station in three days."
In fact, their experimental mission has been completed.
It is not their job to test centrifugal force to simulate gravity experiments. Their job is to test the changes in biosynthetic technology in a microgravity environment.
Meng Haiyang, Zhang Gongyu and others have been doing this for more than half a year.
After a series of tests, they collected a large amount of data.
As expected from the beginning, various biosynthetic fungi and coral polyps have undergone various strange changes in the microgravity environment.
Among these changes, there are good and bad sides.
Regarding this result, the Science Division felt troubled.
After all, according to this test result, it means that in future exploration of the moon, the application of biosynthetic technology will be limited and must be readjusted.
Because the moon's gravity is one-sixth of the earth's, it is significantly different from the microgravity of low-Earth orbit and the earth's standard gravity.
And through this experimental test, the Homo sapiens company has realized the first big problem that will inevitably be encountered in the process of space exploration - the difference in planetary environment.
This is a new cosmic science.
Many of mankind's previous industrial and agricultural technologies were actually based on the earth's environment. Once they leave the earth's environment, they will most likely become unacclimated to the environment.
Zhang Gongyu chatted with Meng Haiyang for a while, and then left David on duty to guard the control cabin while he went to the biological experimental cabin.
In a transparent water tank, there are more than a dozen spherical objects floating. These are spherical objects that will be automatically synthesized by coral polyps if they have sufficient nutrition in a microgravity environment.
Apparently this is due to the effect of microgravity.
Zhang Gongyu quickly took the sensor pen, wrote and drew on the tablet, and filled in various data into the experiment list.
Although he knew that his shift would change in three days, he still insisted on standing on the last shift.
And on earth at this time.
Facing the rapid advancement of the aerospace industry of the Homo sapiens company, other forces were so jealous that they almost separated.
Especially for those big forces, the current situation of not being enough compared to those above and more than enough compared to those below makes them feel even more embarrassed and helpless.
Faced with such difficulties and oppression, a major cooperation called aerospace cooperation has attracted considerable attention around the world.
