Simulated Gravity

"Report, Chief, all personnel have boarded, all citizens have been settled, and all supplies and energy have been properly stored!"

"Report, Chief, the nuclear reactor has been started, the overall power system test is complete, fault point 2 was found to be caused by temperature differences leading to changes in resistance coupling, all have been eliminated, and restart is operating normally."

"Report, Chief, Main Thruster 1 fuel is 100% filled, Main Thruster 2 fuel is 100% filled, Main Thruster 3 fuel is 97% filled."

"Report, Chief, the Thruster Interlocking System has completed linkage testing, signal transmission is normal, remote sensing control is normal, and three-engine linkage simulation is normal, ready to start at any time."

"Report, Chief, Rotating Shaft 1 is energized, Rotating Shaft 2 is energized, Rotating Shaft 3 is energized, Rotating Shaft 10 is energized, all control console digital signals are normal, ten-axis linkage simulation is normal, and single-axis independent movement simulation is normal."

Inside the Hope spacecraft's control center, reports of testing information rose and fell among the staff.

The Hope's control center is also the main control room and cockpit, located on the fifth Rotating Shaft of the spacecraft. It is a clean space, a large cabin approximately 30*12*6 meters in length, width, and height.

Although the cockpit is also located inside the large disk, the floor is very flat. In fact, not only the control room floor is flat, but the floors of all Living Modules and other types of cabins are flat, because humans are accustomed to standing on flat ground, hence this design.

Yue Yuan was sitting in the large chair in the command center, which could be considered the Hope's Captain's seat. In front of the seat, down three steps, stood a large terminal screen. On either side of the large screen were two rows of various types of sub-control terminals.

Now, staff members were sitting in front of the sub-control terminals, either looking at the small screens in front of them, or constantly pressing and dialing on the consoles with both hands, and then reporting the feedback information they received.

Controlling such a large ship cannot be done by one person alone.

Just as now, this cockpit, or rather control center, was filled with crew members of various functions.

There were Helmsman, Second Helmsman, Navigator, Communications Officer, Security Officer, etc., as well as Captain, First Mate, Second Mate, Science Officer, and various clerical staff, and of course, the Chief Engineer and Security Team personnel.

Since the Hope has no weapon systems, there is currently no Fire Control Officer position.

"Okay, connect the Hope's broadcast to the entire ship." Yue Yuan stood up from the Captain's seat, while hooking his foot on the Stabilizer to prevent himself from floating.

"Yes, the broadcast is connected." The Communications Officer quickly operated on the console and responded.

Yue Yuan looked at the large screen, which had been switched to a collection of images from various workplaces throughout the ship, and said, "Ladies and gentlemen, this is the Hope's command center, I am Yue Yuan.

Attention all personnel on the ship, the Hope will officially enter operation in ten minutes. Attention all personnel on the ship, the Hope will officially enter operation in ten minutes.

Personnel still floating in a weightless state, please immediately return to the cabin floor, please immediately tidy up all kinds of floating objects, and secure your body to avoid unnecessary injury."

Although all the supplies and equipment that everyone could take had been brought on board, since the ship had not yet started rotating, everything on board was still in a state of weightlessness.

Many people were still floating in their Living Modules. Although the average Living Module was only two meters eight high, falling suddenly could still cause injury.

Logically speaking, ten minutes was far from enough, but since some preparations had been made in advance, people did not need to tidy up everything, and ten minutes was just right.

During these ten minutes, Yue Yuan did not stand there waiting, but continued to speak on the full-band broadcast: "Compatriots, we came from prosperity, struggled in despair, and rebuilt our home in the ruins. The Hope is the crystallization of our wisdom, a spacecraft built by scientists, engineers, and thousands upon thousands of compatriots with their blood and sweat. Now, it will carry the hopes of all of us and sail to the other shore of life."

"I know some people are reluctant to leave Callisto, reluctant to leave this base that we painstakingly built, but we should all understand that Callisto is only our temporary harbor. The scarcity of energy does not allow us to stay here for long. Now, we are about to bid farewell to Callisto and embark on the sea of stars. Even if the vast starry sky is a long journey, even if the end of the sea of stars hides endless dangers, we will go without hesitation!"

After giving a pre-departure speech, the time quickly came to ten minutes later. Yue Yuan stopped at just the right time.

After turning off the full-ship broadcast, Yue Yuan sat back in his seat, then sat upright and announced, "Begin."

"Understood!"

"Rotating Shaft 1 has been officially closed and energized, the coil is working normally, the magnetic field strength is stable. Rotating Shaft 1 begins to rotate, the first stage preset angular velocity is 0.45 rpm."

"Rotating Shaft 2 is officially closed and energized and begins to rotate, the first stage preset angular velocity is 0.45 rpm."

"Rotating Shaft 3 begins to rotate... the first stage preset angular velocity is 0.45 rpm, running normally, the simulated gravity effect reaches expectations."

"Rotating Shaft 5 begins to rotate, the first stage preset angular velocity is 0.45 rpm."

"Rotating Shaft 10 begins to operate, the first stage preset angular velocity is 0.45 rpm."

"Rotating Shaft coordinated linkage system connected... turntable speed fine-tuning begins."

"Shaft coupling synchronization has been activated, ten Rotating Shafts synchronization completed, simulated gravity at each monitoring point reaches the expected value."

As reports rang out in the control center, the Hope began to rotate from the first turntable to the tenth turntable, slowly at first and then faster. After a while, the Rotating Shaft synchronization coordination system began to coordinate the ten turntables, making them relatively stationary from being fast and slow.

At this moment, everyone on the Hope felt the existence of gravity, and the familiar feeling on Callisto was back.

0.45 rpm is 0.45 revolutions per minute. At this speed of rotation, people on the ship can probably feel the same gravity as they did on Callisto.

This is the first stage preset speed.

People need to adapt!

The Science Officer and engineers on the Hope had considered this.

That means people have been living on Callisto for a very long time. If we suddenly start rotating and bring the ship's simulated gravity up to Earth's level, everyone will probably turn into soft bones immediately.

So, the best approach is to first have the Hope generate the gravity conditions of Callisto, which people have been living with for many years.

After everyone has adapted slightly, we'll proceed with acceleration. The second stage will increase from 0.45 rpm to 0.64 rpm, at which point the simulated gravitational acceleration produced by the Hope will be approximately 2.48 m/s².

Then, after some time, once people's bodies have adapted to this change, we'll proceed with the third stage of acceleration: 0.91 rpm. At that point, the simulated gravitational acceleration produced by the Hope will be approximately 5 m/s².

We'll increase it slowly like this, and by the fourth stage, it will reach 7.6 m/s².

The fifth stage will reach 9.8 m/s².

Of course, because the Living Module has a height difference of about sixty meters, there will be some fluctuation in this value between the lowest and highest levels.
