Six Hundred and Eighteenth, the Brightest Star in the Sky

The military doctor gave Zhang Chao an injection of hibernation agent, and then gave himself another injection. The landing craft became completely quiet, leaving only Ye Han who was frowning and thinking.

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

The direction of flight is not chosen randomly. There is not much fuel on board. If the direction of take-off is wrong, the relative speed between the landing craft and Jupiter will decrease, and the chance of flying away from Jupiter will be lost. It is necessary to determine the orbital direction of this satellite in order to fly away from Jupiter. Make sure the route is correct after takeoff.

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

And this ghostly place can't stay longer, otherwise there is a danger of being captured by aliens.

However, Ye Han knew that the relative speed of the Yuewan and the small celestial body was not high, and the angle was very small. By observing the impact marks left by the Yuewan on the small celestial body, Ye Han roughly determined the direction of the Yuewan before the impact. Thus, the approximate flight direction of the small celestial body can be judged indirectly.

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, and the landing craft flew away quickly, and the black paint soon disappeared. Melting into the sky, after a while, Ye Han could no longer see clearly the small celestial body that left the Moon Bay.

He couldn't tell what it was like in his heart, that is, he was grateful for escaping and ascending to heaven, but also worried about his future fate, and even more indescribably lost and confused.

Ye Han has also undergone systematic daily training, but he has little regret when the book is used. Although the landing craft took off successfully and there should be no problem with the direction, he just couldn't figure it out in his heart, and he always felt that something was wrong.

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

How can I find out the route?

Ye Han doesn't know what the outside of the solar system looks like, but he has a good understanding of the situation in the solar system. Since he has no clue, he can only use the most stupid way to list out the situation he knows first.

First of all, the flight direction of the landing craft should be retrograde around Jupiter, which is consistent with the direction when the Moon Bay cut into the orbit around Jupiter, and the Moon Bay flew more than half a circle around Jupiter before encountering Ion Zero, then the battleship hit the asteroid , the sun should be somewhere directly in front of you.

With Jupiter's orbital height at zero, there should be no retrograde small celestial bodies nearby, but there is no need to worry about this issue, who knows what aliens did on Jupiter.

Secondly, he had been in a coma for a while, and it is not known 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, right, and rear could not be seen clearly. Let's talk about the sun!

He still doesn't know the orbit of the small celestial body. In order to ensure the correct course, Ye Han aimed the laser rangefinder on the boat at Jupiter, and kept an eye on the distance between the landing craft and Jupiter.

Again, Ye Han is very clear about the position of the expedition fleet when it set off. Right now, the earth should still be at 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 position will change. Turning to the 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 suddenly flashed in Ye Han's mind.

No, although it is far away from Jupiter, there are still those constellations on the celestial sphere, and the direction can be judged completely through the constellations, even if it is not so accurate, it will not affect anything!

Ye Han immediately lay down 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 sky full of stars. 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 ran out of fuel before flying out of Jupiter's gravitational range, so it had to keep its course, fly half a circle around Jupiter, and then accelerate to leave.

Only in this way can we return to Earth with limited fuel.

However, easier said than done, once the spaceship departs, Ye Han will inject himself with hibernin. He only knows a general direction, and without detailed orbital data, he may fly to where by then. This is no joke.

Moreover, Jupiter is already the territory of aliens, even if the landing craft is far away from Jupiter at this time, there is a possibility of encountering an alien spacecraft.

Ye Han didn't dare to continue thinking about it, fearing that he would be completely desperate if he continued to think about it, so he quickly aimed the laser outside the cabin at the earth: "Landing craft 104 called the command center, I am Ye Han, the commander of the Yuewan Marine Corps, and the current Yuewan All the surviving officers and soldiers are on the landing craft. The location, orbit and speed of the landing craft are unknown, and the command center is urgently needed to guide us back..."

Worried that the landing craft would encounter an alien spaceship, and no one would know what happened to the expedition fleet, Ye Han told all the situations he knew, trying to let the command center understand the strength of the alien fleet, and the chaotic news followed The laser signal flew towards the earth at a speed of 300,000 kilometers per second.

More than forty minutes later, Earth, Qiongzhou Aerospace 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 had no news for most of the day, and the space telescope on the Tiangong had already confirmed the news that the expedition fleet was wiped out. Signal from the fleet?

"Expeditionary fleet!" The communications staff replied in an unusually positive manner.

"What content?"

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

"Do it now and do your best to bring our hero back."

"yes!"

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

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

Not long after, the combat staff ran to Huo Qiang: "Report, the analysis results are out!"

"Pick the focus."

"Yes!" The combat staff looked ten lines at a glance, "According to the analysis of known data, the battleship lost control when the Yuewan broke through and collided with a small celestial body near Europa. Due to the limited angle, the space telescope failed to capture the details of the impact. The landing craft According to reports, the impact angle and relative speed of the Moon Bay are not large, and they are the survivors of the impact, including the wounded.”

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

Not long 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 the gravity of Jupiter, and flew towards the direction of the earth and the direction of the sun.
