This live broadcast was very eye-opening for netizens, especially when they saw the extravehicular aviation suits with “China Red” elements, netizens all admired the cool and good-looking “space jerseys”. “I look forward to astronauts dressing up.” !” It is reported that the Shenzhou 12 astronauts will work and live in space for three months, during which they plan to carry out two outings. △Liu Boming and Tang Hongbo are referring to the manual to carry out the installation and testing of extravehicular space suit gloves Extravehicular space suits show their true appearance, a touch of “China Red” lights up space The Shenzhou 12 flight crew’s three-month work schedule in space is well-arranged, and one of the most important tasks is to get out of the cabin. Astronauts must wear extravehicular space suits for exiting activities. According to CCTV News, at 9:40 in the morning on June 20, Tang Hongbo was taking out a large blue package from the cabin, which was taken from the node cabin lens of the Tianhe core cabin at 9:40 in the morning. Space suit. With a gentle pull by Tang Hongbo, the extravehicular space suit weighing 120 kg floated into the node compartment. Afterwards, Liu Boming entered the node module and cooperated with Tang Hongbo to remove the blue wrapping cloth. The white extravehicular space suit finally revealed its true appearance. On June 23, CCTV announced the astronauts’ working images in the China Space Station. The in-cabin images showed that astronaut Nie Haisheng was using simulation software to cooperate with the console to conduct the first training of manipulator control subjects for moving out of the cabin. In the node cabin, Liu Boming and Tang Hongbo are conducting extravehicular space suit gloves installation and testing, clothing size adjustment and other work based on the manual. A reporter from Modern Express saw in the picture that this space suit was swollen and swollen, and the design incorporated “China Red” elements. The overall look was full of technological sense and very cool. Many netizens commented, expecting astronauts to put on space suits and change their clothes, letting a touch of “China Red” light up space. Astronaut Nie Haisheng said in an interview before, “The biggest change of the spacesuit this time is the increase in the time for out-of-vehicle support. In the past 4 hours or so, this time it can stay for 7-8 hours; the second is the joint modification. Now, the mobility is better. Then some other electronic devices, including cameras, are added, which may be more helpful to complete the task.” Astronaut Liu Boming pointed out that some corresponding adjustments have been made to the clothing this time, and some materials have been replaced, making it more comfortable to wear than the original. “It turns out that grasping the safety hook is very difficult when crawling outside the cabin, because most of the physical energy is consumed on it. This time I feel that it is time-saving and labor-saving than before. So it is the improvement of this clothing. Compared with Shenzhou VII, we feel that the comfort level is higher.” Interpretation: A new generation of extravehicular spacesuits has a more technological sense Compared with the previous extravehicular spacesuits, the new generation of “Flying” extravehicular spacesuits has added many new elements to the design. A reporter from Modern Express learned that the new-generation outerwear has a total of 6 layers, with functions such as radiation protection, temperature regulation and pressure regulation, as well as a complete life support system. There is only one model of the new extravehicular spacesuit, regardless of gender and size, which can be adjusted to suit the body shape of each astronaut. Under the premise of satisfying wearing comfort and saving energy, it can ensure that the astronauts carry out a series of complex operations and related load tests in an absolutely safe environment when they exit the capsule. Wen Xin, a professor at the School of Astronautics, Nanjing University of Aeronautics and Astronautics, introduced that the space environment is unpredictable and very complex. The characteristics of the extravehicular operating environment such as strong cosmic ray radiation, temperature difference of more than 300 degrees, microgravity, and high vacuum will have a direct impact on astronauts. It even threatens lives. “Without the protection of the extravehicular spacesuit, the out-of-vehicle operation cannot be achieved. Therefore, the design of the extravehicular spacesuit has a lot of considerations and requires high-tech support. Wen Xin said that space suits are divided into two types: outside and inside. The in-vehicle spacesuit is mainly used to protect the astronauts during the launch and return of the manned spacecraft. When the spacecraft loses pressure, it will automatically fill with oxygen and pressure to ensure the safety of the astronauts. The extravehicular space suit is the key equipment for exiting activities. It is a miniature manned spacecraft and personal protective equipment in space that guarantees the working ability and life safety of astronauts during exiting activities. “This time the extravehicular spacesuit is more mobile for astronauts. This detail seems small, but the actual breakthrough is still very difficult. Because if the joints are flexible, they may not be sealed enough to ensure safety. But the seal is sealed. The performance is guaranteed, but there may be no flexibility.” Wen Xin said, “The new generation of extravehicular spacesuits incorporates high-tech aerospace technology, extends the’standby time’, strengthens the life protection of astronauts, and is not only more humane, It is safe and reliable, and has a sense of science and technology. It is an important manifestation of our country’s manned spaceflight capabilities.”

According to the Federal Cartel Office, there are now up to six price peaks. The savings potential for drivers is enormous.

By Jörg Sauerwein, WDR If you refuel in the right place at the right time, you can save a lot of money. At the same petrol station, prices fluctuate by an average of twelve cents per liter over the course of the day. The differences to the competition are even greater: in a city, the differences can be up to 22 cents, according to the Federal Cartel Office.

Several price peaks a day

In the morning the fuel prices are usually at their highest. After that it gets more and more confusing. The prices drop to the lowest point in the evening. But they keep increasing for a short time every now and then. So far, five such peaks have been common in prices, report the Bonn market watchdog. In the past few weeks, however, some providers even had six of these peaks in prices.

High surcharge at motorway filling stations

The price difference to the motorway petrol stations has also increased. According to the annual report, customers there now have to expect around 25 cents per liter more than at a street gas station. The President of the Cartel Office, Andreas Mundt, recommends checking your smartphone before refueling. Many mobile phone apps make it easy to find cheap gas stations.
