"The second stage, the random vibration test."
……
"Okay, the 300-second durability test is complete."
Re-entering the workshop, Tang Hua looked at the satellite prototype on the vibrating table, it was not disassembled into parts, it was okay, it was okay.
The shop supervisor presses a button, and a cable connected to the satellite sends a signal to the satellite's control system.
Then, the satellite's two solar panels, which had been folded, unfolded.
Tang Hua: "That's right, the solar cell can still be turned on....However, the internal circuit still needs to be inspected item by item, including functional testing and visual inspection, to see if there is any sign of damage."
……
In another workshop of the Tianjin Satellite Factory, the satellite prototype was sent into a sealed hexahedron. Two sides of the hexahedron are transparent glass, and the other four sides are covered with black steel plates.
The air extractor slowly drains the air in the hexahedron.When the interior becomes approximately vacuum, a high-power searchlight outside the hexahedron is responsible for simulating sunlight and irradiating the satellite inside the hexahedron to see how fast it is heating up and whether the heat sink can bring out the heat inside the satellite to accelerate Cool down.
Wuliang Suhai.
Although the flight test of the first Dongfeng-1 engine test bomb was normal, Qian Xuesen made a second flight test.When the third-stage engine started to ignite, the Star-Arrow had already flown out of the land, and was about to fly out of the radar measurement and control range. If something happened to the third-stage engine during the official launch, there would be no reference information from the measurement and control station. Just guessing.
When the second Dongfeng-2 was launched, only Ren Xinmin was in Wuliangsuhai. Qian Xuesen and the second Long March-1 test arrow had already set off for Taiyuan.
This is the last test before the launch of Long March-1 and Qianjin-[-]. It is not only a test of the rocket, but also a test of the Taiyuan Rocket Launch Center.

The northern waters of Taiwan.
"Ship 105 arrived at the scheduled location." "Ship 108 arrived at the scheduled location."...
在台北起飞的战斗机的掩护下，105舰“苏州”号、106舰“泰州”号、108舰“福州”号，三艘驱逐舰已经在钓鱼岛-赤尾屿之间偏南的海域等候。和这三艘驱逐舰一起前出的还有4艘01型护卫舰。
"Taizhou tracking radar station is working normally." "Jiguanshan tracking radar station is working normally."
"The Diaoyu Island early warning radar station is working normally."
——On the southeast coast, the radar stations for aerospace measurement and control are Taizhou and Taipei Jiguanshan, Diaoyu Island
The radar station is not dedicated to aerospace measurement and control, but mainly for air alert and search.Under normal circumstances, the radar station on the Diaoyu Islands may not be able to capture the signal at the end of the rocket.
The second Long March-1 test arrow will be launched from the Taiyuan Satellite Rocket Launch Center to the southeast coast.
The Long March-1 was over the mainland while the first-stage and second-stage engines were working.If the inertial system of the rocket is not working properly and the flight trajectory of the rocket cannot be corrected accurately, after the tracking radar finds out, the ground control station can send correction instructions to the rocket.
The second Long March-1 is to test the entire tracking radar system and control system, and to test the direction change of the launch vehicle while flying in the air, which is a necessary operation for satellites to enter low-Earth orbit.

Diaoyu Island-Chiwei Island is also very close to Okinawa. The US reconnaissance plane took off from Kadena and flew three to four hundred kilometers before reaching the sea area where the rocket splashed down.
However, China has announced in advance that this place is a no-fly zone for the exercise. In addition, the 7 warships on the surface can defend against air, and there are MiG-15bis, Tu-2, and Il-28 reconnaissance models that took off from Taipei Airport in the air. Without a big fight, there is no way to rush into the test sea area.
When the U.S. military reconnaissance plane passed by the edge of the no-fly zone, it found the nearest Chinese warship, which looked like a Keeling-class ship. He couldn't help sighing that the U.S. gave China a lot of things.
November 11, 20:9 am.
"The rocket has been launched!"
"The rocket flew normally."
"The separation of the primary and secondary rocket bodies is completed." "The secondary engine is ignited"
"Secondary engine is functioning normally."
From Taiyuan to Taipei, a series of radars kept reporting the rocket's flight status.
The second stage and the simulated third stage + satellite separated, and the latter relied on inertia to slide out of the sky over the Chinese mainland and land in the East China Sea.When it reached the sky above the Diaoyu Islands, the simulated projectile had already drawn an obvious trajectory at high altitude—the simulated projectile also rubbed against the atmosphere violently, and as it heated up, it also heated up the air passing by, showing a flight trajectory.
Finally, the simulated projectile fell into the splashdown area surrounded by seven warships.Although there were no satellites or precision instruments installed, only a radio recorder, the Type 7 frigate quickly started and headed towards the splash point, preparing to salvage the simulated warhead.
Chapter 164, two days of rushing away
"Oh my God, the Chinese are testing ballistic missiles?!"
When the Long March-1 test arrow was launched, the destroyer "John McCain I" was ordered to monitor the sea area west of Okinawa, close to the edge of the no-fly zone designated by China.
The United States has already guessed that China’s designation of the no-fly zone may be to test missiles. In the past, they often drew up no-fly zones in the Bohai Sea and the Yellow Sea. Once the U.S. military's radar directly observed that a target aircraft was shot down by a Chinese air defense missile.
In this Chinese test, neither the USS McCain nor the large radar station in Okinawa failed to capture the Chinese missile in flight.It was not until the altitude of the missile was lower than 30 kilometers that it dragged a long flame, and the radar of the "McCain" did not scan the characteristic signal of the missile several times.
These radar search signals outline the approximate speed and flight direction of the missile. Its flight speed is at least 30 m/s at a height of 1800 kilometers above sea level, and the speed is still 10 m/s when it enters below 1400 kilometers. This is impossible. Is it an anti-aircraft missile or an anti-ship missile, it must be some kind of ballistic missile.
The Seventh Fleet Command not only received the report from the USS McCain, but radio listening stations in Okinawa and Tanegashima also reported the discovery of fast-moving signal sources.
"The Chinese missile took off from somewhere inland. After crossing the Karman line, the short-wave radio transmitter on it began to send positioning signals, so we can infer its performance based on the second half of the track." The staff officer of the Seventh Fleet The results were analyzed, "The flight distance of this missile is greater than 1800 kilometers, and the middle and rear sections are roughly inertial ballistics. Obviously, this is a Chinese medium-range ballistic missile undergoing flight tests."

Washington, Pentagon.
In front of Nathan Twining, Chairman of the Joint Chiefs of Staff, was a map of East Asia-Western Pacific. The staff had just marked many line segments with distances on the map.
The distance from Japan to most parts of Northeast China is about 1500 kilometers.The entire territory of South Korea is within 1000 kilometers.
Okinawa to mainland China, 800 kilometers.The distance to the mountainous Fujian Province is 800-1000 kilometers.
It is 1400 kilometers from the Philippines to Guangxi.
"The ballistic missile China tested on November 11 has been repeatedly calculated by multiple calculation teams, and its range is not less than 20 kilometers. All of the military bases are within the range of China’s missiles.”
The staff came to a conclusion, which Nathan Twining knew was correct, but he still wanted to ask Thomas White, the current chief of staff of the Air Force.
"If the U.S. Air Force wants to eliminate China's ballistic missile threat, how should it fight?"
Thomas White took a deep breath: "Just like the A-1956 plan in 332, launch a full-scale nuclear strike against China. You were in my position in 1956, and you must have read that battle plan."
Twining: "Is there no other way than total war?"
"China has bombers that can reach Japan and the Philippines. If China also deploys medium-range ballistic missiles in the future, the problems faced by the U.S. Air Force after entering Chinese airspace will be doubled. However, General, it is too early to talk about China's nuclear weapons. They Bombing Japan and the Philippines with conventional munitions is not a deadly threat."
Twining: "I doubt that China's intermediate-range ballistic missiles will be combat effective at the same time as their first nuclear weapons."
Thomas White: "The intelligence department only confirmed from indirect channels that the Soviet Union helped China build a gas diffusion plant and possibly a nuclear reactor, but we have not obtained direct spy photos of the scale and construction progress of China's nuclear plant."
Twining: "China always pays attention to cross-model coordination when developing weapons and equipment. Now I have two conjectures. The first is that China's first atomic bomb will be in service at the same time as the medium-range ballistic missile. The second possibility is , the atomic bomb would be in service simultaneously with long-range or intercontinental missiles."
Thomas White: "Maybe 1958 for the former, 1961 for the latter?"
