According to Japan's Kyodo News Agency reported that the United States National Aeronautics and Space Administration (NASA), the Office of the Office of the General Assembly, a summary of the report shows that astronauts in the International Space Station outdoor activities in the wearing of aerospace service serious, may be There will be a shortage in the near future. The reason is that the new type of space suit technology research and development stagnation.
Reported that NASA made about 40 years ago, 18 sets of 18 sets of aerospace suits are still in use, 7 sets in the accident lost or damaged. The remaining 11 sets have been significantly more than 15 years of design life, aging serious. Outside the activities of the helmet inside the water, astronauts feel choking danger and rush to return to the space station situation occurred.
The report said that the current space station reserves of available space suit a total of 4 sets. The status quo is the production of new space suit technology has not been inherited, only from scratch to develop.
The report said that NASA in the three projects, including Mars exploration program separately to promote the development of new space suits, over the past eight years invested 200 million US dollars, but far from the actual use of investment is still far away. Reported that the end of the use of the station to the end of 2024 so far, the remaining space suit is difficult to bear all the extravagant activities, "proposed the establishment of new research and development of space suits.
It is understood that the space suit is also known as the small spacecraft & rdquo ;, equipped with the cruel environment in the space to protect the life of the astronauts maintenance device.
In addition to space station scientific experiments, the equipment parts replacement and repair process also need to wear space suit extravehicular activities, in addition to Japanese astronauts also wear American suits. Star out of Chang long long stay in the space station during the extracurricular activities and the soil Longxiong, Noguchi Cong a space shuttle activities have been used.
Space station is also equipped with Russian space suit, but according to the cabin to prepare the operating standards can not be out from the US cabin. If you need to operate in the US cabin, you have to come from the Russian cabin and long distance in the space to move.
It is reported that NASA cabin activities have a long history, in 1965 in the "Gemini 4" (Gemini 4) "spacecraft for the first time. The current space suit was introduced in the space shuttle program that began in 1981, although improvements were made to increase glove heaters, emergency propulsion devices, but continued use of the original subject.
