Rebirth: Fight For Life

   Chapter 629 Launch of Backup Star

   With the "Shenjian" series of rockets supported by rocket recoverable technology, the launch efficiency is indeed not on an order of magnitude.

   And artificial intelligence that uses quantum computing power has also greatly improved its ability to calculate launch orbit data.

   So just 8 days later, the backup satellite of Flint Space's first lunar exploration satellite was ready to launch again at the insistence of Jian Yushu.

Ye Yeheng looked at him helplessly: "You know, it's not a particularly good launch window now. This time, the requirements for fuel are higher. There are fewer opportunities to adjust the orbit like the last time. The launch is delayed now, and the come in time."

Jian Yushu shook his head: "The same two launches, with one experience, after a comprehensive review and analysis, the team is confident. Even if it fails, it is meaningful. President Gu said that if you spend money, you must also put This team trains."

   Ye Ziheng no longer persuades him.

   This is obviously over the top, and this is not the way to burn money.

   He just said: "What if it fails again this time? What will you do next time? Is your 'monthly' plan still implemented?"

   Jian Yushu's expression was solemn: "Of course I have to implement it! But don't worry, if it doesn't work this time, President Gu decided to assemble a giant satellite in low-Earth orbit first, the kind with special thrusters, and then go."

   Ye Ziheng opened his mouth wide: "Assembly? Do you want to play space docking?"

   Jian Yushu nodded: "That's right!"

   Ye Ziheng really doesn't know what to say.

   Even the Chinese officials have not yet mastered space docking technology.

   On the ground, the brother company Aerospace Science and Industry Group has been working on this for thirteen years. Although the official sample was produced as early as eight years ago, the docking experiments and separation experiments have been done hundreds of times, and it cannot be said that they are completely mastered.

   Everything will have to wait until the actual space docking experiment that was originally planned to be carried out in the next year to verify.

   Here, it involves the normal operation of hundreds of sensors, thousands of gears and tens of thousands of components.

   Just in order to realize the "month-by-month" plan, now even the space docking has to start playing?

   Ye Ziheng feels that times have really changed.

   It’s true that the amount of money a person has, the more inflated it is.

   There were too many places to complain, and he fell silent all of a sudden.

   Forget it, as far as his position is concerned, such a Party A is a good Party A.

   To be good to Party A, be sure to serve well.

   So he reminded the commander of the launch command hall again to do his best.

  For now, let’s hope this launch is successful.

   Failed, although it is possible to get a mission to launch a giant satellite that can be docked and assembled in space, but it is also possible that President Gu suddenly figured it out and felt that it would be better not to play like this.

   is more secure if it succeeds.

  At least after the successful launch, the original "monthly" plan still has quite a few tasks, and Mr. Gu will at least continue to execute it with confidence.

   When it came time to launch, the rocket launch phase of just a few minutes was still successful and the first stage was recovered.

   In low Earth orbit, at least the satellite is in orbit.

   But Ye Ziheng did not relax, because it was the same last time.

   To launch a spacecraft to the moon, under the current technical conditions, it first needs to fly around the earth a few times, change the orbit through the engine, and then pull the apogee of the orbit farther and farther, and finally fly to the moon.

   This is the most fuel efficient.

  This process will be very long, and it takes twenty or thirty hours to fly around the earth.

  So... Ye Ziheng said: "It's normal now, go and rest first, and come back when you want to change your track."

   Jian Yushu nodded, that's what happened.

   Ye Ziheng looked back at the orbit data on the big screen, hoping that after the next orbit change, it would still fly according to the established orbit.

  …

After   57 hours, after a successful second orbit change, the satellite is now back close to the closest point to Earth.

   This time the orbit change will be performed at perigee. If successful, the satellite will enter the lunar orbit and reach the moon after a flight of more than 80 hours.

   The last time there was a problem in this place. Because of the deviation of the orbit to the moon, under the magnification of such a long-distance flight, after the satellite reaches the moon and decelerates, the orbit is always adjusted poorly, and eventually the connection is lost.

  Now, the critical time has come again.

   Ye Ziheng couldn't help but feel a little nervous, glanced at Jian Yushu, but this guy looked very calm.

   "You can really hold your breath, and Mr. Gu really trusts you, so you can arrange it like this." Ye Heng said involuntarily.

   Jian Yushu gave him a strange look: "I don't understand technology, I'm just a supervisor."

   Ye Ziheng was choked.

   is well said. Sure enough, it was President Gu who refused to admit defeat and made such a risky launch plan.

   Jian Yushu sighed: "Actually, I'm also nervous, but it's useless for me to be nervous. I hope the team can learn from the last lesson and make more precise control. They did find some of their own reasons."

   Ye Ziheng nodded, stopped talking, and accompany him quietly waiting for the moment of change.

   There were no errors in the previous two orbit changes, so the satellite is on the correct orbit. It only needs to start the engine according to the predetermined plan and complete the acceleration for the predetermined time with the predetermined thrust.

   This is a very delicate calculation.

As the   propulsion proceeds, the spacecraft also loses mass. Velocity is related to mass, so the entire calculation needs to be done on a number of variables that are constantly changing.

   Ye Ziheng doesn't care about these, he only needs to see if there is any deviation between the recalculated orbit data and the predetermined orbit data after the orbit change acceleration is completed.

   If there is a deviation, you need to recalculate the next adjustment plan and send the new data.

   So, it is best if there is no problem.

  The process of orbit change is very fast. After the orbit change is completed, the new orbit data is also being calculated and generated.

   Ye Ziheng and Jian Yushu both looked at the big screen expectantly.

   After a while, the command hall was deadly silent for a few seconds.

   Ye Ziheng's face was ugly, and sure enough... there was another deviation.

   But it has not reached the point of irreversibility. The deviation this time is much smaller than the last time.

   Now, we need to wait for the track adjustment plan to come out.

  To calculate the fuel remaining now, calculate the best timing for changing orbits and the timing for alternate orbits.

   He patted Jian Yushu on the shoulder: "It's much stronger than last time."

   Jian Yushu nodded, but sighed slightly: "However, the launch window is worse than last time, and the fuel consumption... is also much larger than last time."

   Ye Ziheng complained in his heart: Now you know you are worried about this? I was advised not to be in such a hurry.

  With the blessing of quantum computing and artificial intelligence, the calculation is indeed much faster.

   The answer came quickly: remaining fuel, three more chances!

  When approaching the moon, slow down once.

   If the deceleration phase is successfully completed according to the new data, only one minor adjustment is required to enter the predetermined orbit.

  If this adjustment is not successful, there is only one chance left.

   Ye Ziheng's face is not very good-looking.

   In fact, if you really want to count it, there are only two chances.

   He really couldn't trust the young team of Flint Aerospace.

   But at this time, you can’t make suggestions rashly.

   involves liability after all.

   He looked at Jian Yushu and asked solemnly, "How do you say it?"

   Jian Yushu said in a deep voice, "Of course it is implemented according to the adjustment plan! We have already reached this stage, can we still stop it?"
