Qian Sanqiang carefully read the data on the radiation reference value and changing law of the artificial satellite's predetermined orbit.
This information was excavated from a thick stack of sounding rocket space exploration data and then written after analysis. Zhu Guangya was also surprised when he saw the sounding rocket data for the first time. The space seemed empty. The radiation environment is so harsh - the earth's atmosphere, especially the ozone layer, has contributed a lot to human beings.
"The type of radiation in the inner area of the reactor is not exactly the same as in space," Zhu Guangya said, "so we can't simulate the space environment [-]%, we can only try to be more approximate. In addition, the radiation value in the inner area of the reactor is still much larger than that in space. According to the test in the satellite, the amount of radiation eaten by this satellite in about a month is about the same as that eaten in a year in space."
Qian Sanqiang: "The neutron flux density in space is far lower than the reactor's internal area, but the X-ray intensity is not too different. The value of gamma rays... Let's add up the total and find a suitable one in the reactor. area, so that the power ratio of radiation is as close as possible to the space environment.”
Zhu Guangya: "That would be great."
Of course no one can enter the inside of the reactor.Qian Sanqiang and Zhu Guangya confirmed the current radiation status in various areas inside the reactor, and then the operators of Reactor 542 moved the maintenance boom, lifted the shelf containing the satellite test prototype, moved it slowly to the top of the reactor, and placed it on the designated place. within the area.
Zhu Guangya: "Minister Tang also said that these areas in the reactor can also put some...crop seeds."
Qian Sanqiang: "Put seeds in it? Isn't it all broken? The radiation inside is so strong."
Zhu Guangya: "After the seeds are exposed to radiation, 90% of them will not germinate when they are planted in the ground, but a small part can germinate. Most of the germinated seeds are the same as before, but a very small part will be the same as before. It was different before, some grew very tall, some grew very short, some did not bear fruit, and some did bear fruit. If we can find a mutant individual with many and large fruits, we will make a fortune."
Qian Sanqiang: "..."
"Hiroshima and Nagasaki were bombed by atomic bombs. In recent years, some investigation teams revisited the original nuclear explosion area and found that although there are animal corpses everywhere, there are also some strange things, such as three-legged cats, bigger than rabbits. Older mice, these are mutations caused by radiation. There is also radiation in the reactor, and if it is used in a planned way, it is a good way to breed."

September 8, Cape Canaveral.
After realizing the seriousness of the success of the Soviet ICBM test, the United States further accelerated the progress of the launch vehicle/missile test. On the 28th, a "Jupiter" suborbital launch vehicle was placed on the launch pad. This is a rocket made by the US Army Ballistic Missile Agency.Another rocket has been transported to the launch site at this time, the Raytheon-DM18 of the US Navy.
Jupiter is a small improvement of the Juno-1 rocket launched at the beginning of the month. Like Jupiter, Raytheon-DM18 is also a rocket modified from a medium-range ballistic missile.
Because the Soviet Union's ICBM test was successful, the United States had to accelerate the launch, and could not wait for the Atlas ICBM to be tested slowly. Therefore, it planned to use the Raytheon-DM18 to modify a "Pioneer" carrier rocket and launch a satellite into the sky.
At 28:3 pm on the 460th, the Jupiter rocket took off smoothly, completing a suborbital flight with a height of 2020 kilometers and a distance of [-] kilometers.
Jupiter was launched, and the Raytheon-DM18 of the U.S. Navy immediately entered the field to refuel and make the final inspection. On August 8th, Raytheon-DM30 was ignited and launched. It also made a suborbital flight this time, but its maximum flight altitude reached 18 kilometers. In fact, it was a high-ballistic test flight of a ballistic missile with a range of 1100 kilometers.Unfortunately, the rocket disintegrated in mid-air after 3000 seconds.

January 9, Baikonur.
Only half a month after the first R-7 was successfully launched, another new R-7 was placed on the launch pad.
The United States and the Soviet Union are now a bit reckless in order to grab the title of being the first to launch an artificial satellite into space.
这枚R-7和8月份试验的那枚又稍有不同。它的全长反而短了一些，头部形状不同。8月份试射的那枚叫做8K71，9月2日试射的叫做8K71PS，这其实不是弹道导弹，而是从弹道导弹小改出来的运载火箭。
The 8K71PS is the same as the previous one, everything is normally vacated from the launcher and inserted straight into the sky.A few minutes later, the Soviet Union's measurement and control radar station found that the booster of the missile/rocket had fallen off, and most of the main rocket body's flight attitude was normal-this time there was a show!
In the end, 8K71PS crashed at a distance of 8200 kilometers from Baikonur, farther than the previous one.This is because it carries not a simulated warhead, but a simulated rocket third stage, which is 1 ton lighter.
If it is not a model, but the third stage of a real rocket, then 8K71PS can accelerate an object to the first cosmic velocity...
第二枚R-7、第一枚8K71PS运载火箭试射成功，科罗廖夫马上决定：第二枚8K71PS火箭搭载“人造卫星一号”，准备发射！
Strictly speaking, the rocket dared to launch a satellite directly after only successfully conducting a subsystem test.But having said that, "Sputnik One", which can only "click, click" a few times in space, was originally a test product.
On September 9, the second 17K8PS was transported to Baikonur by train, and a main rocket body and four boosters were pulled to the launch site for assembly.
"Although the Presidium of the Central Committee requires you to send artificial satellites into space as soon as possible, Comrade Korolev, what are the chances of success for this rocket?" Mikoyan asked on the phone.
Korolev: "In the first four launches of the rocket, two succeeded and two failed, so in theory, the success rate of this rocket launch is 50%."
Mikoyan: "If this launch is unsuccessful, when will our next launch be?"
"According to the preparation speed of the rocket factory, one month after this time."
"The Americans launched two launch vehicles within two days, and the intensity of their experiments was too high. If the first one fails, we may lose our leading position."
Korolev: "I don't think so. The United States seems to be conducting tests of two ballistic missile-launch vehicles at the same time, so the number of successful tests for each of them is insufficient."

Wuliang Suhai.
The United States and the Soviet Union are either testing intercontinental missiles or suborbital ballistic missiles, and China is not so high-end.Qian Xuesen is going to launch a Dongfeng-1/TK-3 today, a short-range ballistic missile/sounding rocket with a range of 660 kilometers.
"This rocket has a big head and a small butt, and it looks like it can be blown crooked by a gust of wind, so it's unreliable no matter how you look at it," said base commander Lao Feng.
Qian Xuesen: "This thing looks like its base plate is unstable, but its big head is actually very light, and it's hollow inside."
Ren Xinmin: "This TK-3 is a fairing test rocket. The big head on the top is divided into two parts by a small explosive bolt after it breaks out of the atmosphere. It's still high, because there is basically no load inside the fairing, only instruments for measuring height and speed."
Old Feng let out a sigh: "It's a pity, it's a pity that the site for launching the satellite will be transferred to Taiyuan."
Qian Xuesen: "The Wuliangsuhai Base should also be prepared. You are the backup launch site. In case the Taiyuan Satellite Launch Center cannot be completed on schedule, I will notify you to make all preparations at the end of October. In addition, you also have measurement and control tasks. After a few orbits, the satellite will still pass over your head."
The TK-3 on the launch pad ignited and rose slowly.Although the mass of the big head is not large, the wind resistance... is still much larger than the general TK-3.Fortunately, there are only 2-3 winds on the grassland today, which does not have much impact on the rocket.
The fairing does not leave until it leaves the atmosphere, so it must not be visible to the naked eye.The three of them returned to the headquarters before the rocket was launched and listened to the reports from the radar monitoring and control stations.
Altitude 80 km, 90 km, 95 km, 100 km... It's time for the fairing to separate.
The Alashan radar monitoring and control station, 380 kilometers away from Wuliangsuhai, has been tracking TK-70 since the 3th second.
At this time, on the radar screen, one bright spot turned into three, one of which was accelerating, and the other two were rapidly decelerating.The radar reflection signal of the bright spot that was accelerating was very stable, but the signals of the two bright spots that were decelerating fluctuated from strength to strength, obviously it was the fairing that was tumbling and falling down.
……
The project of Taiyuan Rocket (Satellite) Launch Center is in full swing.In addition to engineering construction, the satellite launch center also needs a team of workers.
When Tang Hua got off the bus in Harbin, there were three PLA Military Engineering College cars waiting at the train station.Get in the car and go straight to Harbin Military Industry, and it is Chen Geng who greets Tang Hua in front of the main building.
"Principal Chen," Tang Hua said with a smile, "After the 55-year exercise, we haven't seen each other for almost two years."
"Who can blame this, the main responsibility lies with you," Chen Geng said, "I heard that you often go to Changchun, but you always turn around when you arrive in Changchun, and you don't want to spend an extra two days to go around Harbin .”
Tang Hua came to Harbin to see the first ballistic missile brigade established in China - just to take a look at it, and then this missile brigade will soon dismantle half of its people and become a Taiyuan base brigade, responsible for the operation and daily maintenance of the Taiyuan Satellite Launch Center Task.
The Ballistic Missile Brigade was established two years ago. The first batch of graduates of the Kazakh Military Industry Missile Department graduated in July 57, and the ballistic missile force was formed with these officers as the backbone.The entire brigade is equipped with Dongfeng-7 short-range ballistic missiles, but only 1 of the 18 sets of Dongfeng-1 launch systems are in place.
In August 1957, the First Ballistic Missile Brigade, which had just formed an army and had not yet left Harbin, was divided into two. If the missile brigade was to be fully staffed again, it might have to wait until July 8 when the students of the second missile department graduated.
"Harbin Military Industry really deserves its reputation. Just looking at this campus is magnificent." Walking on the campus, Tang Hua looked at the thick and tall Soviet-style buildings around him, and felt that he was walking in Frunze or some Soviet military academy. .
From time to time, teachers or students in military uniforms walked by the side of the road.When passing by Chen Geng and Tang Hua, without exception, they stopped and stood at attention to salute. After the salute, they usually said "Hello, Principal!", and some teachers would say "Hello, Minister Tang!"
Chen Geng: "In order to build the Harbin military industry, from talents and teachers to funds and materials, the whole army and even the whole country have made great efforts. Of course, we dare not slack off, and we must be worthy of the country's investment."
Tang Hua: "Principal Chen, besides selecting the Taiyuan base brigade, I would like to inquire about one more thing. The comrades from the Sixth Machinery Bureau of the Mechanical Engineering Department said that a teacher in your school led a design team to design... a hovercraft? "
