... which never stopped and now with breakthroughs in nuclear propulsion. More news from Russia.
Scientists have created a composite to protect astronauts from radiation. The new material based on lanthanum hexaboride and aluminum-magnesium alloy is designed to replace expensive foreign analoguesScientists from Russia have developed a composite material designed to protect astronauts and equipment from radiation in space. According to the press service of the Integrated Scientific Center of the Russian Academy of Sciences, its cost is much lower than foreign analogues. The new material is based on lanthanum hexaboride and aluminum-magnesium alloy using plasma sintering technology. It combines high mechanical strength and an effective ability to absorb ionizing radiation."NASA is working on a lightweight material based on boron nitride nanotubes, which can be embedded in the skin of ships and spacesuits. However, its production is extremely expensive - up to $ 1000 per gram. Our task is to create a composite 100-200 times cheaper, while maintaining the quality and effectiveness of radiation protection," explained Oleg Shichalin, head of the laboratory at Sakhalin State University. Specialists from KSC RAS, the Far Eastern Federal University and Sakhalin State University participated in the development. The created composite makes it possible to create multifunctional elements for spacecraft that simultaneously perform a load-bearing function and provide radiation protection, which contributes to the lightening of the structure.
