Nobody knows that the New World Columbus set foot on what outfit to wear one, but in the July 20, 1969, when Armstrong taken on the moon, "his one small step, one giant leap for mankind" when we know that he was wearing We are specifically tailored to suit the task, model A7L, number 056. What price at the time was $ 100,000 (converted to the equivalent of $ 670,000 today), if you have the concept of "fashion" is to measure, it is indeed a little high. However, when you count the space helmet, gloves and backpacks after oxygen, which is basically a wearable spaceship. This dress has a 21-layer composite materials, including neoprene elastomers and metallized polyester film, which protects the surface of the moon Armstrong from extreme heat and destroy arctic temperatures (240 degrees Fahrenheit during the day, at night to minus 280 degrees Fahrenheit ), as well as the sun's deadly radiation and the potential at 10 miles per second flight of small particles of meteorite impact threat.
Apollo plans to use the space suits, combining cutting-edge technology and traditional handicraft tailoring. Every suit by a group of high female workers sew handmade 1/32 inch error, is a spacesuit and cook mop difference. Before the moon program, all the materials needed for space suits and ready, but first test sample has been produced. In 1967, a failed landing experiments, three Apollo astronauts planned because after the fire sacrifice, NASA requires all spacesuits must be able to withstand more than 1,000 degrees Fahrenheit temperatures (537.78 degrees Celsius). The solution is the most advanced, is called "Bei Tabu (Beta Cloth)" material made of Teflon fibers, is used in the outermost layer of the suit.
Bear suit manufacturing tasks situated Delaware, Dover City "International Latex Corporation ILC (International Latex Corporation)," The biggest challenge is the need to provide sufficient pressure spacesuits astronauts survive (in pure oxygen environment 3.75 lbs per square inch), but also flexible enough to provide joint activity. Engineers ILC interior, responsible for the production of bras and shapewear sectors like "tight and comfortable" demand to know. They invented a joint unit called "neoprene swivel (a convolute out of neoprene)", which is reinforced by a nylon braid strength, can make the Astros a relatively easy way to rotate the shoulder, elbow, knee , waist-hip and ankle joints. Handling wire rope used on the aircraft is used to support the whole space suit, absorb the pressure, keeping clothing shape.
For Armstrong, that means he can flexibly collect valuable lunar rocks and dust samples to help another fellow astronaut Buzz Ao Delin carry out a series of scientific experiments, and then the moonwalk, the he still planned, but a shot of about 200 meters high, the landing site crater photo - without worry is living in a multi-layer material in a space suit to protect them, and the vacuum of the universe isolated. 1994 a quarter of a century later, Armstrong wrote a letter of thanks to NASA, thanks NASA made him through that piece suit, he wrote: "There is no doubt that it is so photogenic ah, it It is the history of most outbound spacecraft. " The letter also his trademark self-deprecating: "This dress wore it succeeded in that ugly block a tightly."
Armstrong said: "It's really nice, because it really works."
