Apollo 11 astronauts in spacesuits set foot on the Moon for the first time. Photo: NASA Hollywood films often draw attention with the iconic spacesuit, the design of which makes the public believe that it is a costume that can be taken off within minutes. But in fact, the spacesuit is a “spaceship” with its own full function, requiring the wearer to take off or take off with the help of colleagues. Cathleen Lewis, curator of international space programs and spacesuits at the Smithsonian Institution’s National Air and Space Museum, said: “The purpose of the spacesuit essentially exists as a humanoid spacecraft, allowing astronauts to autonomously explore and do meaningful work outside of spacecraft or space stations.” Ms. Lewis said it can take up to four hours for an astronaut to get dressed, from start to finish. Before going to space, astronauts must check each piece of equipment and make sure they have enough essential supplies, such as oxygen and water. During the spacewalk, they will be supported by a team from Earth. Watch Apollo astronauts in spacesuits fall up and down in zero gravity on the Moon (source: NASA) Sarah Korona, extraterrestrial flight control specialist at NASA’s Johnson Space Center in Houston (Texas), said: Flight controllers must adhere to a plan of procedures about 30 pages long, but still have other plans if problems arise. The “anatomy” of a space suit According to NASA, a spacesuit is made up of 6 different components and can have up to 16 layers.
Astronauts on the Artemis missions, NASA’s next program to send the first woman and first black man to the Moon, will wear the latest spacesuit, called the Visitor Mover. alien probe, abbreviated as xEMU. Before the spacesuits reach the Moon, their components will be tested on the International Space Station (ISS). NASA unveiled a prototype of the xEMU suit in 2019 at the agency’s headquarters in Washington. Photo: NASA One of the key components of the new spacesuit is the cooling fiber, said Richard Rhodes, vice president of xEMU pressurized garment development at NASA. The suit is made of tubes that help circulate water around the astronauts, regulating their body temperature and removing excess heat as they complete their work. According to NASA, each spacesuit has a portable life support system, which includes a water tank to cool the clothes, a carbon dioxide removal system, and other components, including a two-way radio for astronauts to communicate. Previous spacesuits used in the Apollo missions were less flexible than those used today. “When the Apollo astronauts walked on the Moon, they couldn’t bend down and pick up a rock,” said NASA astronaut Mike Fincke. They had to have a particularly compact tool with a handle mounted on it.” The space suit of astronaut Neil Armstrong during the Apollo 11 mission in 1969. Photo: NASA But the spacesuit has come a long way since then and has a more flexible construction, with active support gloves. According to Ms. Lewis, gloves are one of the most complicated parts of a spacesuit, and they are often the source of most complaints from astronauts about their suits. “Gloves are difficult to design to both protect and allow astronauts to demonstrate manual dexterity to get the job done,” the expert notes. Pressure gloves can also contract, especially after long hours in space. The astronaut’s fingers are also cold, so heating elements need to be built into the glove. Gloves are an important part of the spacesuit that NASA designed for the mission back to the Moon. Photo: NASA When astronauts train for space flight, one of their training exercises includes picking up a coin in a spacesuit while underwater, Ms. Lewis said. These explorers need extreme dexterity when working in space, and gloves are a big challenge. Much of astronaut spacesuit training is conducted in a swimming pool at NASA’s Laboratory in Houston. Water simulates the feeling of weightlessness, similar to the feeling in space. To develop the spacesuit, scientists have experimented with a variety of materials and with varying degrees of success over the years. At one point, researchers experimented with Kevlar fingertips (a fiber five times stronger than steel) on gloves. “The Kevlar material is very useful in blocking bullets but not very good at stopping knives – it is very easy to cut,” Ms. Lewis said. Astronauts currently use synthetic plastic gloves, but scientists are always looking for better options. In addition, the outside of the spacesuit has color stripes specific to each suit. Here’s how astronauts can tell who’s wearing which suit while in space. Crafting the Artemis . space suit The first step in designing a spacesuit is “understanding who you’re designing the suit for, what you want them to be able to do, and where you want them to be able to,” says Rhodes. For the Artemis program, NASA needed their astronauts to be able to safely explore the Moon’s surface. Prototype of new spacesuit, xEMU, by NASA. Photo: NASA Over the past four years, NASA has invested more than $300 million in the development of the xEMU suit. Richard Rhodes’ team tested dozens of ingredients and weighed the pros and cons of each. He said the biggest challenge for the Artemis suits was making sure they were optimized for exploration of the Moon. The suits needed to be “light enough to support a mission to the Moon and sturdy enough to protect astronauts when working in very dangerous environments”. According to Rhodes, there are thousands of parts produced to make the Artemis spacesuit, and they are sourced from all over the United States. Some parts can take up to a year to build, but NASA is working to shorten the time. Space suits will also be upgraded for the latest Moon mission. Current and past NASA spacesuits allow only minimal movement of the waist, hips, or ankles. Artemis astronauts need to have extra mobility. to be able to explore the rough terrain of the Moon, so Mr. Rhodes’ team is working on a suit that allows for more movement while still being sturdy enough to protect the wearer.

“ The solutions contained in the bottles of Hazoku brand hand sanitizer located in the T1 passenger terminal area are Disinfectant (Hipochloro Acid bactericidal solution) “, a representative of Noi Bai International Airport said. This representative also said that this antiseptic solution, produced from Japanese OSG machines, was sponsored by BPS Vietnam Trading & Service Co., Ltd free of charge for the Port to use in the prevention of the COVID-19 epidemic. The hand sanitizer at Noi Bai airport was reported by customers as plain water. (Internet photo). This is a colorless, odorless, safe, environmentally friendly hand sanitizer solution and has been tested by: National Institute of Infectious Diseases of Japan; Pasteur Institute City. Ho Chi Minh City – Ministry of Health and Quatest 3 Center – General Department of Metrology of Vietnam. Hipochloro acid solution is very effective in inactivating viruses, has outstanding antibacterial effect and ensures that it meets the standards of disinfection against COVID-19. Because the Hipochloro Acid disinfectant solution that the Port is sponsored is packaged in 20L cans, for the convenience of passengers at many locations of the terminal, the Port has temporarily used small plastic bottles. Hazoku brand – which is a system of Hazoku dry hand sanitizer bottles that have been used up by the Port for the purpose of reuse.

How to calculate safe sun protection time for skin Illustration. The SPF number on the cream cover indicates the level of sun protection. Each SPF unit provides 10 to 15 minutes of skin protection. This formula is for those with little sun exposure or with another layer of protection. Example: You buy a sunscreen with SPF 30. You will take 30 x 10 (or 15 minutes) = 300 (or 450 minutes), equivalent to 5 hours or up to 7.5 hours. In addition, another method is applied to girls who are often exposed to the sun. The formula to calculate the sun protection time for the skin is based on the sun protection index and the time the skin is irritated in the sun. Depending on each skin, this formula gives different results. For example: When going out in the sun, how long does it take for your skin to start burning and red, it’s time to get irritated under the sun. The average time is about 5 minutes, the skin will show signs of itching, burning, So you have time to protect your skin from the sun with SPF 30 cream line: 30 x 5 = 150 minutes, about more than 2 hours. Whatever the formula is, sun protection is actually governed by many factors. The intensity of the sun where you live, the level of oil secretion, the perspiration of the skin, the quality of the cream used, the UVA or UVB protection, whether it’s a physical or chemical cream, etc. Therefore, the best way to determine is based on the feel of the skin. If the skin begins to “react” by sweating, it shows that the place is sunny, mildly burning, the foundation is thinner, the skin is light as if there is no makeup … are “reminding” signs that you need to reapply the sunscreen. sunny. So to determine how long sunscreen will last, the most effective way is to rely on the “voice” of the skin. Things to avoid when using sunscreen – Need to avoid water when using sunscreen: Because water will reduce the skin protection effectiveness of sunscreen a lot. Therefore, when using sunscreen, you should not bathe, or if bathing, you need to dry your body and apply sunscreen immediately after; – Avoid applying sunscreen on the mucous membranes of the eyes and mouth: Because this skin area is very sensitive and sunscreen can cause irritation, this area of ​​​​skin can be damaged; Avoid sweating when applying sunscreen: The fact that you sauna, do a lot of physical activity causes sweat in the body to escape and wash away the sunscreen, so the sun protection effect for the skin is also greatly reduced. ; Avoid combining sunscreen with other topical medications: Because it is possible that the ingredients in topical medications will interact with the sunscreen, causing skin irritation, reducing the effectiveness of the cream. Sunscreen, the healing effects of topical drugs are many.

The common point of selling ambiguous quality is that often the reason fabrics with UV protection cannot distinguish the quality of fabrics with the naked eye. Accompanied by a series of … international certificates. Anti-UV, no need for specialized products According to Assoc.Prof. Dr. Nguyen Manh Tuan – Deputy Director of the Institute of Applied Materials Science, there are many forms of radiation around us, high-energy radiation is electromagnetic, low-energy radiation is infrared. UV rays are classified as high energy radiation, capable of penetrating deep through clothing and causing damage to the skin. There are three types of UV rays: UVC (short wave light), UVB (strong impact on the skin’s surface, causing redness, sunburn and skin cancer risk), UVA (with the longest wavelength, penetrating depth). under the skin, causing skin aging and wrinkling). UPF index is an index evaluating the level of protection of a fabric material from UVA, UVB rays. The higher the UPF index, the lower the amount of UV light penetrating the fabric. An effective sunscreen should be made from fabric with a UPF rating of 15 to 50+, which is about UPF for the best skin protection. Normally, synthetic fibers such as polyester or nylon will be more resistant to UV rays than cotton. Depending on the fabric material that can block UV rays, at different levels. If the fabric is resistant to UVA and UVB rays, the manufacturer must add anti-UV chemicals (this chemical is also known as UV). But whether the chemical is good or not, the ability to resist UV rays, the index of any number must be tested and certified by the Vietnam Textile Institute. “Cheap products on the street, because there are no measuring tools to check, so I do not know for sure what materials they use, whether they are dyed with anti-UV chemicals or not, how much UV protection is. If they use materials that are not good enough, do not dye UV chemicals but increase the product thickness, they can also block UV rays, just the level of resistance can not be maximized as advertised “, Assoc.Prof.Dr. Nguyen Manh Tuan said. Dr. Huynh Khanh Duy – Chemical Engineering Department, Ho Chi Minh City University of Technology said that no matter what material a product is made of, as long as UV rays cannot be penetrated, it is able to protect against the sun. Therefore, whether it is synthetic fiber fabric, cotton fabric, denim fabric, khaki … just thick enough is enough to effectively protect against the sun but the price is quite cheap. But in return, these products can not bring the desired coolness in the hot sun. “With products dyed with anti-UV chemicals, depending on the type of chemical used well or not, the dye will pass through the washing times. Many products on the market today do not announce how much UV protection, so UV resistance is also in the form of … bad luck. If you don’t have money to buy an expensive UV protection product, just take any shirt, put it in the sun, if the sunlight cannot penetrate the fabric hole, the product is highly UV resistant and vice versa. again “, Dr. Huynh Khanh Duy confirmed. According to MSc.Vu Thi Phuong Thao – Deputy Head of General Planning Department, Ho Chi Minh City Dermatology Hospital – some sunscreens can protect against UV rays but with a certain ability and still cannot replace cream Sunscreen. Although using coats, masks, gloves, glasses … consumers still have to coordinate with sunscreen to fully protect the skin when going out in the sun. The SPF number on a sunscreen product demonstrates the ability to protect the skin against UVB rays, the sunscreen used must be a broad spectrum, water-resistant and have an SPF of 30 or higher. If you must be active outdoors and sweat a lot, repeat the cream every 2 hours. (According to Women HCMC)

Keeping the nail polish on for too long: Keeping the nail polish on for too long can cause the nail polish’s pigments to seep into the nail’s outer layers, causing the nail to dry out. Experts also recommend leaving a week or two between manicures so that the nail can “breathe”. Do not wash your hands thoroughly: It is a fatal mistake to ignore your nails when washing your hands, as this will allow bacteria to build up under the fingernails, increasing the risk of spreading the bacteria through your diet. Clean your nails every day. Use your fingernails to open the lid of objects: You should stop the habit of using your fingernail to open the lid of water cans, tear the covers of objects, scratch phone cards, or anything else you could use tools to. finished instead of the nail. Washing dishes without wearing gloves: When soaked in water, nails will swell, leading to weak, brittle nails. Plus, the detergent can dry nails and skin on your hands. It is best to wear rubber gloves when washing dishes or doing jobs that have come in contact with water and other detergents. Cleaning without gloves: Just like washing dishes, cleaning without gloves can make your nails ugly, weak, and brittle. Alcohol-based cleaners are especially harmful to nails. Don’t protect your hands in winter: When the air gets dry and the temperature gets low, protect your nails and hands with warm gloves. In addition, you should also use hand cream to moisturize your hands. Don’t eat veggies: What you eat is reflected right through your fingernails. Iron-rich foods like eggs, spinach or red meat can help strengthen nails.
