I have a little black hole

Having said that, Zhang Hanxiu opened a new analog video, that is, the analog video of the detector's flight after the flight failure of the assembly was intuitively displayed.

"Look, boss, after they leave the assembly by themselves, they can fly to their destinations and get into orbit smoothly just because of their own flying ability. After all, we have considered this, so each detector comes with The fuel is very abundant.

However, if this happens, the working hours of these detectors will be greatly affected. The detectors that can work for up to 10 years, after such a toss, may only work for 2-3 years. When the orbit change fuel is used up, it can only fall as the orbit continues to decrease.

At the same time, there will be a certain lag in the time when the probe flies to the respective target planet, but in general, the problem is not big, it will be much faster than our re-launch of the probe, and it will not delay our solar system detection plan. !

We can only work for a period of 2-3 years. We can accept it. After all, there is a buffer for this time. Our follow-up detector reissue plan has had enough time to adjust and redesign. In this case, even if the combined launch occurs If there is a problem, the launch cannot be regarded as a failure, it can only be said that it was not successful enough!Zhang Hanxiu said with a smile.

After seeing the simulation screen, Lei Tiantang nodded his head with confidence and approved the design. All the considerations should be taken into consideration. If I worry about this, I will launch various detectors in the future. Take a conservative launch mode?

"OK! Since you should have thought about everything, then follow this design!" Lei Tiantang nodded with a smile.

Seeing his boss nodded in approval of the design, both Zhang Hanxiu and the surrounding staff were relieved. After all, if such a design that breaks through the tradition is rejected, then they need to reuse the previous one by one. Launch these detectors in launch mode, then their workload will become very large.

It will also delay the entire solar system exploration plan for a longer period of time, and will inevitably drag down the company's entire space program, which is why they have painstakingly proposed this new design.

"By the boss, in order to ensure that this design is reliable, we also designed two rounds of test launch missions to verify the reliability and advanced nature of this launch mode!" Zhang Hanxiu said and opened two new ones. projection.

"Look, boss, this is our relay satellite launch plan and asteroid belt probe launch plan. We plan to use these two launch plans to practice!

The first plan is to launch a combination of relay satellites. Since this launch plan launches special relay satellites with only high-speed signal reception and forwarding functions, these satellites are exactly the same, which means that they can be mass-produced.

And because they have a single function, their bulk is not large, and the weight of a single relay satellite is only 500 kg. With such a weight, with the carrying capacity of our company’s rocket, 30 relay satellites can be launched at one time. To earth transfer orbit.

If it is not the reason for the satellite volume, there is no way to launch too much at a time. According to the actual carrying capacity of our company’s rockets, we can even launch more than 100 at a time!

But even so, our planned test assembly is equipped with two large ion engines and a rocket booster, plus a folding solar sail with a diameter of 100 meters, and the core of the assembly-120 relay satellites, These things are added together and it is OK to launch 7 times!

After the successful launch of these 120 relay satellites, we can basically meet the signal forwarding task of our company's solar system detection plan for the next 10 years. Significance.

The satellite detector of the asteroid belt detection program is twice as heavy as the relay satellite, and the weight of an asteroid satellite detector is one ton. After all, they need to have many times during the asteroid detection mission. The orbit change operation, because it is necessary to avoid collisions of asteroids and space debris, and to detect more than one asteroid.

In this case, the asteroid satellite probe needs to carry more orbit changing fuel, and because it is a detection task, the various components of the satellite are also a little more, so its weight will be twice that of the relay satellite. .

In this case, the number of asteroid satellite probes that we can carry for the first time in the test combination launch mission can only be 60, but this is also in our plan.

After all, whether our asteroid satellite detector can adapt to the detection mission of the asteroid belt also needs to be verified by this launch. 60 are enough to cover all angles of the asteroid belt, so the data collected is enough for us The next launch provides data support.

These two rounds of test launch plan will probably cost 1.2 billion US dollars, but we think the value of this money, what do you think of the boss?Zhang Hanxiu detailedly introduced the two screens projected.

"Very good! Your consideration is very comprehensive! Launching so many satellite detectors actually costs only 1.2 billion US dollars, which is not much for our company!" Lei Tiantang laughed and affirmed these two test launch plans.

He did not feel that this $1.2 billion test mission was a big sum of money. After all, even if such a test is not conducted, whether it is the relay satellite launch plan or the asteroid belt satellite probe launch plan are all in the company’s space program. Part of it is something that must be done. If it is launched separately, it will be troublesome and time-consuming, and it will cost more.

"Hey, as for the boss, you think that there are not many US$1.2 billion. The vast majority of companies in the world can earn a net profit of US$1.2 billion a year. Money, our company's "Wow! Wow!" A few moments later, it's already a very rich thing, okay!" Fang Huiran heard his boss saying that he couldn't help but spit.

"Haha! I can’t say that! The money for space launch is just right. If our 180 satellites are to be launched by other companies, 5 billion dollars will not necessarily be available. Didn’t you think you were taking advantage of it?” Lei Tiantang laughed and laughed.

"Boss, you're saying that! It's more than 4 billion US dollars!" Fang Huiran laughed.
