Chapter 458 Ferris Wheel
Homo sapiens space station.
Captain Meng Haiyang woke up from the hibernation capsule.
"Captain, good morning." Sayashi Kō floated up with a smile.
The two of them quickly finished washing up and then came to the main control cabin.
Maung Chuangxin, who was on duty, saw the two of them and yawned: "Ha... Good morning."
"Chuangxin, go and have a rest!" Meng Haiyang patted his shoulder.
"Then I'll leave it to you. By the way, the Earth headquarters sent a notice two hours ago that the next batch of astronauts will be sent here to take over the shift in three days." Maung Chuangxin said as he floated towards the living module.
"Yeah." Meng Haiyang nodded.
And Sha Yuegong checked the work log of nearly eight hours.
At this time, the scale of the Homo sapiens space station was unprecedentedly large.
The 133,200 tons of supplies, plus the 5,600 tons that the space station already had, increased the weight of the entire space station to 138,800 tons.
37 Spark spacecraft are combined to form a huge "Ferris wheel"-shaped space station.
The Spark is 50 meters long and 10 meters in diameter. When the four Sparks are docked together front and back, they can form a 200-meter-long arm.
The four sets of long arms are connected to the middle universal connector of another central axis (which is also composed of four Spark ships docked front and back).
This formed a central axis inserted in the center of a "cross", and the four outer ends of the "cross" were connected to two Spark ships respectively, forming a "T" shape.
This required the use of 28 Spark ships.
The remaining nine Sparks carried a large number of ring-shaped components. After these components were assembled, they formed two concentric rings, one large and one small, on the "cross".
Their previous 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, I'll go to the outer ring area."
"be safe ."
"rest assured!"
Meng Haiyang floated towards the fire cabin No. 12 below.
After opening the negative pressure gate, he stood on the electric cart and turned the acceleration switch. The cart immediately moved forward along the guide rails on the cabin wall.
After passing through a series of negative pressure gates and traveling a distance of 300 meters, Meng Haiyang finally arrived at the outer ring area of the space station.
He secured the electric cart and picked up the intercom: "Sha Yue Gong, start the rotation system."
Sayako's voice came from his headset: "Okay, be safe!"
The eight Spark cabins in the outer ring area began to start the auxiliary electric fuel injection thrusters, and the entire space station began to rotate slowly.
The speed was not fast at the beginning, but the specific impulse of the electric fuel injection propulsion system was very high, so it accelerated continuously for 20 minutes.
Meng Haiyang already felt his body was very heavy.
This is the centrifugal force generated during the rotation of the space station that 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 gravity coefficient of the earth.
And because the radius of the space station reaches 200 meters, the difference in centrifugal force gradient in the outer ring area is not obvious.
However, the special detector in Meng Haiyang's hand can clearly see the centrifugal force gradient difference data. At the same time, he checked the centrifugal force gradients in other areas of the space station.
The data shows 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, what's the situation?"
Meng Haiyang pressed the call button: "It's OK, but a little bit top-heavy. But this feeling of being down to earth is really nostalgic!"
"That's good. Notify me immediately if anything happens."
The rotating system was tested for more than seven hours, during which time Meng Haiyang tried various tests, including eating, bathing and simulated sleeping in the outer ring area. The effect of simulating gravity was quite good.
However, you can still clearly feel some differences from real gravity.
At this time, the other two astronauts in the space station also woke up from the hibernation module.
After Zhang Gongyu and David woke up, they washed up quickly.
On the way to the control cabin, Zhang Gongyu felt that the space station was slowly rotating. Although it did not look obvious, he could still feel the weak centrifugal force of the rotation.
Come to the control cabin.
"Doc! David! Good afternoon." Sha Yuegong and the two nodded.
"How was the rotation system test?" Zhang Gongyu asked curiously.
Sayashi Kou smiled and replied, "The pseudo-gravity in the outer ring area is OK and can be used . The captain is in the outer ring area."
After a while.
Meng Haiyang also returned from the outer ring area to the central axis area.
As he floated up, he rubbed his temples and said, "Huff... It feels so uncomfortable in the rotating arm area, especially the few dozen meters near the central axis area."
"It looks like there's a lot of trouble in the rotating arm area!" Zhang Gongyu said as he recorded the incident in his work log.
Meng Haiyang shook his head helplessly: "Besides, the rotating arm is not long enough. If the radius can reach 500 meters, the gradient difference of the centrifugal force will be so small that it can't be felt."
"500 meters? We can't enjoy it. I guess we can only wait for the next batch of astronauts to come and test it." Zhang Gongyu replied with a smile.
Sayashi Ko interjected, "The next group 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 biosynthesis technology in a microgravity environment.
Over the past six months, Meng Haiyang, Zhang Gongyu and others have been doing this.
After a series of tests, they collected a large amount of data.
Just as expected at the beginning, various biosynthetic fungi and coral polyps showed all kinds of strange changes in the microgravity environment.
There are good and bad sides to these changes.
The Science Division felt troubled by this result.
After all, according to this test result, it means that the application of biosynthesis technology in future exploration of the moon will be restricted and must be readjusted.
Because the gravity of the moon is one-sixth of that of the earth, there is a significant difference between this and the microgravity of low-Earth orbit and the standard gravity of the earth.
Moreover, through this experimental test, Sapiens has realized the first major problem that will inevitably be encountered during space exploration - differences in planetary environments.
This is a new science of the universe.
Many of the industrial and agricultural technologies before human beings were actually built on the earth's environment. Once they leave the earth's environment, they are very likely to suffer from acclimatization problems.
Zhang Gongyu chatted with Meng Haiyang for a while, then left David on duty in the control cabin while he went to the biological experiment cabin.
There are more than a dozen spherical objects floating in a transparent water tank. These are spherical objects that are automatically synthesized by coral polyps when they have sufficient nutrients in a microgravity environment.
Apparently this is due to the effects of microgravity.
Zhang Gongyu quickly took the induction pen and wrote and drew on the tablet, filling in various data into the experimental list.
Although he knew that he would have to change shifts in three days, he still insisted on standing guard for the last time.
And at this time on Earth.
Faced with the rapidly developing aerospace industry of Sapiens, other forces are so jealous that they are almost breaking apart.
Especially for those big forces, the current situation where they are not as good as the best but better than the worst makes them feel embarrassed and helpless.
Faced with such difficulties and oppression, a major cooperation called Space Alliance has attracted considerable attention around the world.
