University of Manchester scientists have created this new material, which is made from extra-terrestrial dust, potato starch, and a pinch of salt that could be used, at least in prinicple, to edify living units on the Red Planet.<\/p>\n\n\n\n<p>In a <a href=\"https:\/\/www.manchester.ac.uk\/discover\/news\/scientists-develop-a-cosmic-concrete-that-is-twice-as-strong-as-regular-concrete\/\">press release<\/a>, the institution explained that building infrastructure in space is currently prohibitively expensive and difficult to achieve. Future space construction will need to rely on simple materials that are easily available to astronauts. StarCrete offers one possible solution. The scientists behind the invention used simulated Martian soil mixed with potato starch and a pinch of salt to create the material that is twice as strong as ordinary concrete and is perfectly suited for construction work in extra-terrestrial environments.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Houses made from potato chips\" width=\"563\" height=\"1000\" src=\"https:\/\/www.youtube.com\/embed\/S6_tCTfYPrI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Better, less invasive components<\/strong><\/h2>\n\n\n\n<p>In an <a href=\"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/eng-2022-0390\/html\">article<\/a>, the research team demonstrated that ordinary potato starch can act as a binder when mixed with simulated Mars dust to produce a concrete-like material. Starcrete made from moon dust was even stronger.<\/p>\n\n\n\n<p>This work improves on previous research from the same team where they used astronauts\u2019 blood and urine as a binding agent. While the resulting material had a compressive strength of around 40 MPa, which is better than normal concrete, the process had the drawback of requiring blood on a regular basis. When operating in an environment as hostile as space, this option was less feasible than using potato starch.<\/p>\n\n\n\n<p>\u201cSince we will be producing starch as food for astronauts, it made sense to look at that as a binding agent rather than human blood&#8221;, said University of Manchester research fellow Dr. Aled Roberts. &#8220;Also, current building technologies still need many years of development and require considerable energy and additional heavy processing equipment which all adds cost and complexity to a mission. StarCrete doesn\u2019t need any of this and so it simplifies the mission and makes it cheaper and more feasible.&#8221; Besides that, astronauts probably don\u2019t want to be living in houses made from scabs and urine.<\/p>\n\n\n\n<p>The team calculate that a sack (25 Kg) of dehydrated potatoes (crisps) contain enough starch to produce almost half a tonne of StarCrete, which is equivalent to over 213 brick\u2019s worth of material. For comparison, a 3-bedroom house takes roughly 7,500 bricks to build. Additionally, they discovered that a common salt, magnesium chloride, obtainable from the Martian surface or from the tears of astronauts, significantly improved the strength of StarCrete.<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link advgb-dyn-1adadb67\"><a href=\"https:\/\/ioplus.nl\/archive\/en\/colonize-and-live-on-mars-thanks-to-cyanobacteria\/\" class=\"vlp-link\" title=\"Colonize and live on Mars thanks to cyanobacteria?\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">Colonize and live on Mars thanks to cyanobacteria?<\/div><div class=\"vlp-block-1 vlp-link-summary\">A trip to Mars takes about nine months with current spacecraft.

Resources must be both created and recycled on Mars. <\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\"><strong>Next, sustainable steps<\/strong><\/h2>\n\n\n\n<p>The next stages of this project are to translate StarCrete from the lab to application. Dr Roberts and his team have recently launched a start-up company,&nbsp;DeakinBio, to explore ways to improve StarCrete so that it could also be used in a terrestrial setting.<\/p>\n\n\n\n<p>If used on earth, StarCrete could offer a greener alternative to traditional concrete. Cement and concrete account for about eight percent of global CO<sub>2<\/sub>&nbsp;emissions as the process by which they are made requires very high firing temperatures and amounts of energy. StarCrete, on the other hand, can be made in an ordinary oven or microwave at normal \u2018home baking\u2019 temperatures, therefore offering reduced energy costs for production.<\/p>\n","protected":false},"author":2583,"featured_media":524258,"template":"views\/single-selected.blade.php","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[75667,76370],"tags":[129930,5872,129932,129935,129937],"location":[55977],"internal_archives":[],"class_list":["post-440766","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-innovation-origins","category-science","tag-living-on-mars","tag-mars","tag-mars-infrastructure","tag-space-concrete","tag-university-of-manchester-3","location-united-kingdom"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2021\/02\/newsimage346220.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/francesco-morelli\/","display_name":"Francesco Morelli"},"relative_dates":{"created":"Posted 3 years ago","modified":"Updated 3 years ago"},"absolute_dates":{"created":"Posted on March 21, 2023","modified":"Updated on March 21, 2023"},"absolute_dates_time":{"created":"Posted on March 21, 2023 11:08 am","modified":"Updated on March 21, 2023 11:08 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/category\/innovation-origins\/\" class=\"advgb-post-tax-term\">Innovation Origins<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/category\/science\/\" class=\"advgb-post-tax-term\">Science<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">Innovation Origins<\/span>","<span class=\"advgb-post-tax-term\">Science<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/living-on-mars\/\" class=\"advgb-post-tax-term\">living on mars<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/mars\/\" class=\"advgb-post-tax-term\">Mars<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/mars-infrastructure\/\" class=\"advgb-post-tax-term\">mars infrastructure<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/space-concrete\/\" class=\"advgb-post-tax-term\">space concrete<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/university-of-manchester-3\/\" class=\"advgb-post-tax-term\">University of Manchester<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">living on mars<\/span>","<span class=\"advgb-post-tax-term\">Mars<\/span>","<span class=\"advgb-post-tax-term\">mars infrastructure<\/span>","<span class=\"advgb-post-tax-term\">space concrete<\/span>","<span class=\"advgb-post-tax-term\">University of Manchester<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/\" class=\"advgb-post-tax-term\">EN<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/?taxonomy=post_translations&#038;term=pll_641984af0899a\" class=\"advgb-post-tax-term\">pll_641984af0899a<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">pll_641984af0899a<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/location\/united-kingdom\/\" class=\"advgb-post-tax-term\">United Kingdom<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">United Kingdom<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/440766","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2583"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/524258"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=440766"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=440766"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=440766"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=440766"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=440766"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
