Armor Frenzy

The military doctor injected Zhang Chao with a dose of hibernating agent, and then injected himself with another injection. The landing craft completely quieted down, leaving only Ye Han, who was frowning and thinking.

The alien fleet could arrive at any time, Ye Han did not dare to stay on the asteroid, and immediately increased the engine power, the landing craft successfully flew away from the asteroid with weak gravity without much effort.

The direction of flight is not a random choice. There is not much fuel on the boat. If the take-off direction is wrong, the relative speed between the landing craft and Jupiter will decrease, and the opportunity to fly away from Jupiter will be lost. The orbital direction of the satellite must be determined. Make sure the route after takeoff is correct.

The best way to determine the direction is to observe nearby celestial objects. Jupiter itself is very clear, but the satellites near Jupiter are much worse, and it is impossible to see celestial objects near Jupiter without optical equipment no matter how good the eyesight is.

And this ghost place can't stay too long, otherwise there is a danger of being caught by aliens.

However, Ye Han knew that the relative speed of the Moon Bay when it collided with the small celestial body was not high, and the angle was also very small. In this way, the approximate flight direction of the small celestial body can be indirectly determined.

After the landing craft took off, Ye Han took one last look at the broken Yuewan, silently raised his right hand to bid farewell to the battleship and the sacrificed comrades in arms, pushed the joystick forward fiercely, the landing craft flew away quickly, and the black painting soon disappeared. Blending into the sky, after a while, Ye Han could no longer see the small celestial body that left the Moon Bay.

He couldn't tell what it was like in his heart, not only the joy of escaping and ascending to heaven, but also the worry about the future fate, and the loss and confusion that he couldn't tell.

Ye Han can be considered to have undergone systematic training, but when the time comes, he hates little. Although the landing craft took off successfully, there should be no problem with the direction, but he just can't figure it out, and he always feels that something is wrong.

Spaceflight is not a child's play. It is a thousand miles away. As long as he makes a single mistake, everyone, including himself, will be buried in Jupiter, which is hundreds of millions of kilometers away from the earth.

How can I find the route?

Ye Han doesn't know what it looks like outside the solar system, but he still understands the situation inside the solar system. Since he has no clue, he can only use the stupidest way to list the situations he knows first.

First of all, the flight direction of the landing craft should be retrograde around Jupiter, which is the same as the direction when the Moon Bay cut into the route around Jupiter, and the Moon Bay flew around Jupiter for most of the time before encountering Io, then the battleship hit the asteroid , the sun should be directly in front of it somewhere.

With the orbital altitude of Io Zero, there should be no retrograde small celestial bodies nearby, but there is no need to struggle with this issue. Only ghosts know what aliens have done on Jupiter.

Secondly, he was in a coma for a period of time, and he did not know how long he had been in a coma. At this time, the sun could not be seen directly in front of the landing craft, and the situation on the left and right sides and the rear could not be seen clearly. Say it to the sun!

He still doesn't know the orbit of the small celestial body. In order to ensure the correct route, Ye Han pointed the laser rangefinder on the boat at Jupiter, always paying attention to the distance between the landing craft and Jupiter.

Once again, Ye Han is very clear about the position of the expedition fleet when it set off. The earth should still be in its original position, but he can't figure out the current posture of the landing craft. As long as the landing craft rolls 180 degrees, the original left will change. Right, resulting in a misjudgment and flying in the wrong direction... At this moment, he saw the Big Dipper outside the porthole!

A flash of lightning flashed across Ye Han's mind.

No, although it is far away from Jupiter, the constellations on the celestial sphere are still those, and the direction can be judged completely by the constellations, even if it is not so precise, it does not matter!

Ye Han immediately lay on the porthole, looking around for the position of the sun.

The sun seen in the orbit of Jupiter is very small, but it is not to be confused with the starry sky. Ye Han soon found the trace of the sun in the side and rear direction.

At this time, turning around and flying towards the sun is courting death. Maybe it will run out of fuel before flying out of Jupiter's gravitational range. You must maintain your course and fly around Jupiter for more than half a circle before accelerating away.

Only then can it be returned to Earth with limited fuel.

However, it's easier said than done. Once the spacecraft leaves, Ye Han will inject himself with hibernin. He only knows the general direction and has no detailed orbital data. He might fly somewhere by then. This is not a joke.

Moreover, Jupiter is already the territory of aliens. Even if the landing craft is far away from Jupiter at this time, it is still possible to encounter alien spacecraft.

Ye Han didn't dare to think further, for fear that he would be completely desperate if he thought about it any longer, so he quickly pointed the laser outside the cabin at the earth: "Landing craft 104 calls the command center, I am Ye Han, commander of the Marine Corps of the Yuewan. All the surviving officers and soldiers are all on the landing craft. The location of the landing craft is unknown, the track is unknown, and the speed is unknown. We urgently need the command center to guide us to return..."

Worrying that the landing craft would encounter the alien spaceship, then no one would know what happened to the expedition fleet. Ye Han told everything he knew, and tried to let the command center understand the strength of the alien fleet as much as possible. The laser signal flew towards the earth at a speed of 300,000 kilometers per second~www.readwn.com~ More than 40 minutes later, the earth, Qiongzhou Space Command Center.

"Report, Chief, just received a signal from the expedition fleet!"

Huo Qiang's eyes widened in surprise: "Where did you say the signal came from?" The expedition fleet has been out for a long time. The space telescope on the Tiangong has confirmed the news that the expedition fleet has been wiped out. Fleet signal?

"Expedition Fleet!" The communications staff replied with an unusually positive answer.

"What content?"

"A dozen survivors on a landing craft, requesting the command center to navigate."

"Go ahead and do your best to bring our hero back."

"Yes!"

"Notify Tiangong that I want an image of Jupiter, mark the signal source for me, and give me the analysis result as quickly as possible."

The picture on the big screen immediately changed to Jupiter, and a small point of light was marked near Jupiter.

After a while, the combat staff rushed to Huo Qiang: "Report, the analysis results are out!"

"Pick the point."

"Yes!" The combat staff looked at ten lines, "According to the analysis of the known data, the battleship lost control when the Yuewan broke out of the siege and hit a small celestial object near Io Zero. Due to the limited angle, the space telescope failed to capture the details of the impact. The landing craft The news said that the angle and relative velocity of the Moon Bay impact were not large, and they were the survivors of the impact, including the wounded."

"I didn't expect it!" Huo Qiang sighed, "Send the data as soon as possible!"

Soon after, Ye Han received a laser communication from the space station, and after starting the remote control mode of the landing craft as required, Ye Han injected himself with hibernin.

After another day and a half, the landing craft accelerated away from Jupiter's gravity and flew toward the earth and the sun.
