In the direction of the sun, a huge orange disk swelled with blows.

The spacecraft rotates around the earth, and its current orbit is elliptical. After two slowdowns, the spacecraft will enter the atmosphere in four hours.

This was the best choice Arthur and Nami could make after some intense calculations.

Utilize minimal fuel consumption while procrastinating for more time.

"It's useless, and the longer we're in orbit, the higher the chance we'll get hit by debris and rocks, and the more damage we'll get to the spacecraft."

Nami said worriedly.

Arthur could hear his pulse beating heavily.

Although he tried his best and did nothing wrong, he still found nothing. Arthur felt ignorant about this area of ​​the solar system.

The facts obviously shouldn't be like this. The stars have not dimmed. The orange star is still burning fiercely like a heart. Huge energy is stored there. The burning plasma can instantly vaporize everything close to it without a trace.

.

After dozens of seconds of silence, Nami suddenly shouted: "Arthur, look, what is that?"

Arthur tilted his head back, and then he saw something that made Nami exclaim.

Floating in the distance is a twenty-first century International Space Station.

"This is the last human-made structure recorded in the Earth's version of the World Heritage List. It can be said that since then, the World Heritage List has officially entered the space age." Arthur saw the International Space Station from the monitor, portholes and periscope.

, there is no doubt that this space station does not look retired yet.

Although its solar array must be scarred, it is still in orbit, and it seems so friendly at this time.

Arthur felt that it was difficult to breathe, not because of insufficient oxygen supply in the helmet, but because his consciousness was beating rapidly, and along with his heavy heartbeat, he had a bold idea.

"We're going there," Arthur told Nami.

Nami:......

"Senior sister, if we are lucky enough, we may be able to repair the energy group of the Galapagos Islands and continue to complete the mission."

"You mean docking with the space station?"

"Yeah, let's go up there and see what we can find."

Nami's calculations were very fast. During the conversation with Arthur, she had already calculated how much risk they needed to take.

Nami's heartbeat had never been so fast, and her crazy calculations and repeated self-denials failed to defeat her determination to go to Earth and complete her mission.

"The probability of success is less than 10%," she said.

Arthur nodded slowly through his helmet, "Yes, after two orbit changes, we may find a docking opportunity."

"It's not possible, but we will definitely get the opportunity to dock. The problem lies in our fuel reserves. Arthur, the fuel needed for orbit change will be gone when it is used up, which means we have no chance of trial and error."

"Sister, we don't have the chance to try and make mistakes again, do we? After setting foot in space, when have human beings ever had the chance to try and make mistakes? It is said that the ancestors on the planet often use a word - life and death, what they call life and death

Most of them are still about individual life and death, but after setting foot in space, all our decisions require detailed discussion and repeated calculations. This is because when facing the hope and crisis of the universe, we have long had no chance to make mistakes, but we still develop.

After hundreds of years, our science is still making progress, and the population is multiplying endlessly."

Nami was not convinced, she ruled out other possibilities to continue the mission, and finally found that the only way they had left was to try their luck on the space station.

"First we need to increase the orbital altitude. We are now on the space station. In addition, adjusting the angle difference also requires energy."

"It will be enough." Arthur has also completed the calculation.

"After reaching apogee, the spacecraft needs to get used to the second boost, that is..."

"Hohmann transfer, we can do it."

"Arthur, listen to me, time, the problem is time."

"The Nebula International Space Station orbits the Earth in 90 minutes. After two accelerations and several decelerations, and adjustments to its angle and orbit, we have to catch up with it and successfully dock. Judging from the current situation, it will take at least a day."

"I know that the stable orbit-changing docking method is not suitable for us. We need to use a faster method to achieve docking."

"you mean?"

"When I was in the preparatory school, the courses were relatively relaxed, and the teachers also liked to tell us some interesting stories about the history of space in addition to the standard courses. We would be surprised every time we heard those stories, and we often had to hold our breath to finish them.

I dared to gasp loudly only after the professor's lecture.

Those real stories are more amazing than science fiction movies. One of them I remember clearly is that in the early 21st century, Russia used a method to quickly dock with the space station. It only took three hours at that time.

The connection was achieved.”

"This is impossible. It is possible to launch a rocket from the earth and then quickly dock with the space station. In fact, if the space station is operating normally and the relative position of the rocket launch point and the space station is in the best state, when the rocket is launched, the earth

To get the orbital plane of the space station, if the angle between the space station and the spacecraft is very different, it is impossible to achieve rapid docking. The spacecraft will take a long time to catch up with the space station. Therefore, if you want to dock quickly, unless the International Space Station happens to be at the time of the rocket launch,

Above the rocket launch site, the angle and height difference can be limited to a small range, shortening the chase time.

To do all this, the most critical thing is to adjust the orbital position of the space station. How can we adjust the position of the space station now?"

Nami couldn't understand what Arthur was thinking. Although the idea of ​​going to the space station was definitely a good idea, they couldn't afford to wait any longer. The vacuum bubble would not slow down its expansion just because they were docking with the space station.

"No, although we can't adjust the position of the space station, we can reduce the chasing distance. Don't wait until the spacecraft enters apogee before making the second orbit change. We are afraid that we will change orbit midway. In this way, we only need to circle the earth twice to reach the destination.

Right location, the disadvantage is that we will consume more energy."

Shen Shen appears in the main cabin. The space station can no longer be seen, but it will appear in the periscope again soon. Should we take the risk?

If the mid-course acceleration method is successful, it will only take more than three hours for them to dock with the space station.

In this way, the task does not waste too much time, and everything can be started again.

"Senior, this is worth trying. I think of a sentence that Mark Twain said - comedy is tragedy plus time."
