Can the return capsule still be used?
The re-entry capsule could not be used anymore. On the one hand, the mission of the return capsule had very high requirements for the hardware of the capsule and the high-precision instruments inside. After experiencing a high temperature of up to 2000 ° C, it was difficult to ensure that all its components would not be damaged again, which would affect its service life. For the absolute safety of the astronauts, the return capsule could not be used again. On the other hand, the outer surface of the return capsule was made of composite materials. The burning of this outer layer material reduced the temperature transmitted to the return capsule to solve the high temperature resistance problem when the spacecraft returned to Earth. This material was disposable. Instead of reinstalling heat-resistant materials, it was better to directly use a new return capsule. However, from the perspective of cost and resource utilization, there were also ideas for recycling the return capsule, but there were still huge technical challenges.

How many times can the return capsule be used?
The return capsule of China's Shenzhou series spacecraft cannot be reused at present and will be retired after completing the mission. However, the return capsule of China's new generation of manned spacecraft can be reused 10 times. The return capsule of Russia's "Eagle" manned spacecraft is part of the low-Earth orbit infrastructure.(At least 356 days), 10 flights to the moon for no more than 30 days, and no more than 3 - 4 flights to the moon for no more than 180 days as part of the lunar orbit infrastructure. The total service time of the return capsule was 10 years. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
Return capsule time
Different re-entry capsules took different times. The following is an example of the time taken by some re-entry capsules: 1. On April 12, 1961, the Soviet Union's Major Yuri Gagalin returned after 108 minutes of orbiting the Earth in the "Vostok 1" spacecraft. 2. On February 20, 1962, the American astronaut Lieutenant Colonel O'John H. Glenn flew the Mercury 6 spacecraft around the Earth three times and returned after 4 hours, 55 minutes and 23 seconds. 3. When China's Shenzhou 17 astronauts returned, they had to go through a five-minute dangerous black-out zone and then safely wait for landing, but the total time was not mentioned.

Can the return capsule be reused?
At present, the return capsule of the Shenzhou series spacecraft was a one-time use and could not be reused. However, the new generation of manned spacecraft return capsules that China was developing could be partially reused, and it was planned to achieve the reuse of return capsules in the next few years. In addition, China's new generation of manned launch vehicle (Long March 10) derived from the unboosted configuration of the rocket with a sub-stage with a re-use function.

The return capsule of God 18 successfully landed
At 01:24 on November 4,2024, the Shenzhou 18 manned spacecraft return capsule successfully landed at the Dongfeng landing site. The on-site medical supervision and medical insurance personnel confirmed that the astronauts Ye Guangfu, Li Cong, and Li Guangsu were in good physical condition. The Shenzhou 18 manned flight mission was a complete success. The novel," The Couple's Universe: The Amazing Legend of Shen Zhen " is equally exciting. Everyone is welcome to click and read it!
The return capsule passed through the black barrier
The return capsule passing through the black barrier was a critical and dangerous stage in the space return process. When the re-entry capsule entered the Earth's atmosphere at a very high speed (between 35 and 80 kilometers), it would rub violently against the dense atmospheric molecules. This friction produced a temperature of up to 2000 degrees Celsius, enough to melt most metals. At such a high temperature, the air around the return capsule was ionised, forming a plasma layer that wrapped around the return capsule like a lid. This layer of plasma not only isolated heat, but also blocked the transmission of electromagnetic waves, causing the return capsule to completely lose contact with the ground. This was the black barrier phenomenon. In the black barrier area, the return capsule lost contact with the outside world for several minutes (for example, Shenzhou 18 lost contact for five minutes). This period was a life-and-death test for the astronauts. Any small malfunction could cause a disaster, and the ground control center could not know the specific situation inside the return capsule. In order to deal with the danger of the blackout, scientists had made a lot of efforts. For example, the development of special heat-resistant materials, such as the honeycomb-shaped heat-resistant material outside the Shenzhou 18 return capsule, which melted and vaporized at high temperatures to protect the astronauts. There was also a sophisticated navigation system that allowed the return capsule to rely on its own system to accurately adjust its flight attitude to ensure a safe landing. In addition, there were also explorations in communication technology. For example, neutrino communication technology. Neutrinos basically did not interact with matter. If they could be used for communication, they could penetrate the black barrier to achieve real-time communication. There was also plasma sheath technology, which absorbed and reflected electromagnetic waves by forming a plasma "protective cover" around the return capsule to reduce the effects of the black barrier.

How can a time capsule story be used to teach history?
A time capsule story can show students real - life artifacts from a certain time period. For example, if it has old coins, it can teach about the economy then. Simple things like a matchbox can tell about the manufacturing of that era.
How can 'time capsule short stories' be used in education?
Time capsule short stories can be used to teach history. For example, students can read stories about real - time capsules and the items in them to understand what life was like in a certain period.
How can a time capsule comics gift card be used effectively?
You can use it to purchase your favorite time capsule comics or related products. It's simple and straightforward.
Is Novell still used?
Not really. Novell has become less prevalent in the current tech landscape. It was popular in the past, but new systems and software have largely overtaken it.
Tongbian capsule
Tongbian capsule was a type of Chinese patent medicine. Its main ingredients included xylo-oligosomes, aloes, pumpkin, tremella, and other ingredients that had the effect of relaxing the bowels and nourishing the intestines. It has the effect of regulating the function of the stomach, strengthening the spleen and kidney, and relaxing the bowels. Tongbian capsule is suitable for improving constipation, dry stool, defecation fatigue, primary constipation, habitual constipation and other conditions. It mainly had the effect of health care and had few side effects. However, for people with severe constipation, it is recommended to use regular drugs for active treatment and conditioning. Don't be superstitious about the efficacy of health care products. For people with frequent constipation, they should pay attention to diet conditioning, eat more food containing more crude fiber, eat more vegetables and fruits, and exercise more. In short, Tongbian capsule was a health care product for laxatives and intestines, but for people with severe constipation, it was recommended to consult a doctor and use regular drugs for treatment.
