Public domain film from NASA, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization. en.wikipedia.org A space suit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes... Some of these requirements also apply to pressure suits worn for other specialized tasks, such as high-altitude reconnaissance flight. Above Armstrong #39;s Line (around 19000 m/62000 ft), the atmosphere is so thin that pressurized suits are needed. The first full pressure-suits for use at extreme altitudes were designed by individual inventors as early as the 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961... Hard-shell suits Hard-shell suits are usually made of metal or composite materials and do not use fabric for joints. Hard suits joints use ball bearings and wedge-ring segments similar to an adjustable elbow of a stove pipe to allow a wide range of movement with the arms and legs. The joints maintain a constant volume of air internally and do not have any counter force. Therefore, the astronaut does not need to exert to hold the suit in any position. Hard suits can also operate at ...From:webdev17Views:6 2ratingsTime:03:53More inScience Technology
