Chapter 371

Academician Wu is Wu Zheng's father.

Then the thing is well explained.

Gu Lu estimated that it should be because of Academician Wu that Wu Zheng named him to come over here to help.

Gu Lu opened his mouth to get down to business, "Listen to my senior brother, Chief Engineer Wu asked me to come here by name?"

Wu Zheng smiled slightly, and did not deny it, "We need a high-level mathematician for our project team now, and my father recommended you to me." ”

"I don't know what Chief Engineer Wu needs me to do, within my ability, I will definitely go all out. ”

"Professor Gu, don't worry about this, you should be coming to us for the first time, I'll take you around first. ”

After speaking, Wu Zheng took Gu Lu to walk around the research base.

The Chang'e-4 project consists of five systems: a probe, a launch vehicle, a launch site, TT&C, and ground applications.

On the side of Gu Lu's scientific research base, it is responsible for the research and development, production, and testing of the Chang'e-4 probe.

This is the main part of the Chang'e-4 lunar exploration program!

Of course, the lunar rover on the probe is also in charge of the scientific research base here.

Not long ago, the name of the lunar rover was officially named "Yutu 2" after voting by Everbright netizens.

Chang'e, Jade Rabbit.

Both are taken from ancient Chinese folklore, and have a very special meaning in the minds of the people of Guangda.

Wu Zheng passed the iris identity verification and brought Gu Lu to the detector.

Some engineers are installing some equipment on the detector.

Gu Lu only knew a small part of the relevant knowledge in this area, so he was confused.

Wu Zheng glanced up at the detector more than ten meters high, and explained to Gu Lu with a smile, "Chang'e-4 is actually the backup machine of Chang'e-3, and the two are almost identical. However, after its launch a few years ago, Chang'e-3 successfully landed a lunar probe on the surface of the moon and released the Yutu lunar rover to explore the moon rocks, successfully completing the mission. ”

"So, the existence of Chang'e-4, a 'stand-in', does not have much meaning to exist, but the China National Space Administration is unwilling to dispose of this behemoth that costs hundreds of millions of dollars as waste, so it cooperated with experts from the Chinese Academy of Sciences and relevant aerospace departments to formulate the Chang'e-4 exploration plan, and it was at that time that I was successfully elected as the chief engineer of the Chang'e-4 lunar exploration project. ”

"Chang'e-4 and Chang'e-3 are responsible for different lunar exploration, this time Chang'e-4 is to land on the far side of the moon, which is much more difficult than landing directly on the front side of the moon, we have improved this probe according to these requirements. ”

Wu Zheng stroked a black cuboid instrument inside the detector with his hand and introduced it to Gu Lu, "We removed the extreme ultraviolet camera that was originally located in this position and replaced it with this low-frequency radio spectrum analyzer. ”

The role of the extreme ultraviolet camera is to observe images of the Earth from the Moon.

It's just that this time the Chang'e-4 probe landed on the far side of the moon, and the earth can't be seen at all, so the role of the extreme ultraviolet camera is quite weak.

The low-frequency radio spectrum analyzer is a scientific payload independently developed by China.

It is installed on the probe, and the natural and clean environment without the interference of the earth's electromagnetic waves on the far side of the moon is used to detect the low-frequency radio characteristics of the sun during the lunar day, and the low-frequency radiation environment on the lunar surface is detected, and the lunar space environment above the solar eruption and landing area is studied.

Ideal for data acquisition on the far side of the Moon.

"What about this one?" Gu Lu pointed to a half-human-tall instrument on the other side.

"This is a neutral atom detector that we developed in cooperation with Sweden, and its main purpose is to detect neutral atoms and ions on the surface of the moon, where the neutral atom detector will monitor the interaction between the solar wind and the lunar surface. Wu Zheng said.

"This guy is estimated to be very expensive, right?" After listening to Wu Zheng's introduction, Gu Lu said after estimating.

Wu Zheng raised five fingers and said with a painful expression, "From research and development to the official production of the finished product, a total of 50 million has been invested!"

"But that's not the worst of it. Wu Zheng pulled Gu Lu to a spherical instrument, pointed at it and said, "This big guy is the most expensive!"

Gu Lu leaned over and scanned the back and back of the instrument, and found a label on the back of the instrument.

The label is all in English.

It bears the name of the instrument – the Lunar Surface Neutron and Radiation Dosimeter Detector.

Underneath the name of the instrument, there is also a logo printed on it.

However, to Gu Lu's surprise, the logo was not the logo of the China National Space Administration.

But......

"NASA?" Gu Lu was stunned for a moment and looked up at Wu Zheng, "This instrument was made by the National Aeronautics and Space Administration of the United States?"

Wu Zheng smiled bitterly and nodded, "That's right, we bought this lunar surface neutron and radiation dose detector from NASA." ”

"This instrument, at present, in the world, only NASA (NASA) can manufacture it, and we spent 70 million to buy this instrument from the United States. ”

When he said this, Wu Zheng looked helpless.

Gu Lu was silent for a long time.

Seventy million, the value of this instrument is certainly not that expensive.

But it can't be helped!

That's the tech blockade!

If the technical level is backward, we must be prepared to be slaughtered.

Knowing that this was the cruel reality, Gu Lu was still a little angry.

As a young generation of scientific research workers in China, Gu Lu felt for the first time what a heavy burden he was on his shoulders.

"Technical blockade, I don't know when, I can let that group of guys in the United States feel this pain!"

Gu Lu shook his head and put this thought aside for the time being.

It's a pretty long-term thing, and you can't rush it.

Wu Zheng then introduced several other devices inside the detector for Gu Lu.

This time, the probe carried a total of nine instruments and detection equipment.

In addition to the low-frequency radio spectrum detector, the neutral atom detector, and the lunar surface neutron and radiation dose detector, there are also six low-frequency radio detectors, landing cameras, panoramic cameras, terrain and geomorphology cameras, lunar radars, and infrared imaging spectrometers.

Among these nine instruments, only the lunar surface neutron and radiation dose detector was purchased directly from NASA, and the remaining eight were all independently developed by China or successfully developed in cooperation with other countries.

This is much better than when the first lunar probe, Chang'e-1, was launched more than a decade ago.

At that time, there were only four detectors installed on the probe, two of which were purchased from abroad.

Wu Zheng raised his wrist and glanced at the time, "Professor Gu, it's not too early, let's go to the radar laboratory and meet with the other members of the team." ”

Gu Lu wiped the sweat from his forehead, "No problem." ”
