Musk has repeatedly said that building the first sustainable city on Mars would require around 1,000 Starship rockets and roughly 20 years of launch campaigns, moving up to 100,000 people per favorable Earth-Mars alignment and eventually reaching about one million settlers plus millions of tons of cargo.<\/p>\n\n\n\n<p>It sounds like science fiction with a project plan. Yet the language he uses, \u201csustainable city,\u201d is very familiar to climate and energy experts here on Earth. So what does sustainability really mean on a frozen, air-thin world and how does that huge effort interact with the environmental crisis on our own planet?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Starship numbers in everyday terms<\/h2>\n\n\n\n<p>Long before the first stainless-steel prototype rose from the Texas coast, Musk was already arguing that humanity should become \u201c<a href=\"https:\/\/www.ecoticias.com\/en\/musk-and-trump-behind-mars-revolution\/10977\/\">multi planetary<\/a>\u201d to survive possible catastrophes on Earth. Starship is his chosen tool for that job.<\/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=\"Starship | Third Flight Test\" width=\"1200\" height=\"675\" src=\"https:\/\/www.youtube.com\/embed\/ApMrILhTulI?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><figcaption class=\"wp-element-caption\">YouTube: <em>@SpaceX<\/em>.<\/figcaption><\/figure>\n\n\n\n<p>The vehicle is a fully reusable, super heavy lift rocket designed to carry on the order of 100 to 150 metric tons of cargo to low Earth orbit before refueling and heading to deep space. Musk has talked about building Starships quickly, flying them many times per year and using each Mars launch window, which opens about every 26 months, to send large fleets toward the <a href=\"https:\/\/www.ecoticias.com\/en\/mars-in-just-90-days-highway-to-mars\/16810\/\">red planet<\/a>.<\/p>\n\n\n\n<p>In practical terms that means a lot of hardware. A recent report on his Starbase presentation noted that he wants to scale production up until Starship factories rival the combined annual output of major airplane makers. That is a staggering industrial effort even before we ask how a city would actually function once it arrives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A harsh planet that runs on resourcefulness<\/h2>\n\n\n\n<p>Mars is beautiful in telescope images, but as a home it is a brutal place. Its atmosphere is extremely thin, with a surface pressure less than one percent of Earth\u2019s, and is made up of about 95 percent <a href=\"https:\/\/science.nasa.gov\/resource\/cross-section-of-buried-carbon-dioxide-ice-on-mars\/\" target=\"_blank\" rel=\"noopener\">carbon dioxide<\/a> with only traces of oxygen and water vapor. Average temperatures sit well below freezing. Step outside without a suit and you would be unconscious in seconds.<\/p>\n\n\n\n<p>Because of that, every breath, every sip of water and every bite of food for a Martian city has to be created and recycled in a controlled system. That is where a concept called in situ resource utilization comes in, the idea of using local materials instead of hauling everything from Earth.<\/p>\n\n\n\n<div class=\"gb-element-a00da4e5\">\n<div><div class=\"gb-looper-46613eed\">\n<div class=\"gb-loop-item gb-loop-item-a8390598 post-32385 post type-post status-publish format-standard has-post-thumbnail hentry category-environment resize-featured-image\">\n<h3 class=\"gb-text gb-text-24a51617\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/errors-detected-in-hundreds-of-sea-level-studies-and-the-new-figures-could-change-coastal-risk-maps-across-half-the-world-and-it-is-far-from-a-minor-correction\/32385\/\">Errors detected in hundreds of sea-level studies, and the \u201cnew\u201d figures could change coastal risk maps across half the world\u2026 (and it is far from a minor correction)<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>NASA has already tested one piece of that puzzle. Inside the Perseverance rover a small device known as <a href=\"https:\/\/www.nasa.gov\/missions\/mars-2020-perseverance\/perseverance-rover\/nasas-oxygen-generating-experiment-moxie-completes-mars-mission\/\" target=\"_blank\" rel=\"noopener\">MOXIE<\/a> has successfully turned the carbon dioxide in the Martian air into pure oxygen. Over two years it produced about 122 grams of oxygen in total, peaking at around 12 grams per hour. Enough for a small dog to breathe for a few hours, not a million people.<\/p>\n\n\n\n<p>Other research groups are exploring low-temperature <a href=\"https:\/\/arxiv.org\/abs\/2404.00800\" target=\"_blank\" rel=\"noopener\">systems<\/a> that could make both oxygen and <a href=\"https:\/\/www.ecoticias.com\/en\/musk-finds-the-perfect-fuel-atmosphere\/17158\/\">methane fuel<\/a> from Martian air and water ice, potentially offering more efficient ways to power habitats and rockets in the future. Step by step, scientists are showing that basic ingredients for life support and propellant can be made on Mars, but at laboratory scale rather than metropolitan scale.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sustainability when failure is not an option<\/h2>\n\n\n\n<p>For a Martian city the word \u201csustainable\u201d is not about green branding. It is about survival. Recycling would have to be nearly total. Water would circulate again and again through filters and treatment plants. Organic waste would feed into bioreactors and greenhouses. Air would be continuously cleaned, monitored and topped up.<\/p>\n\n\n\n<div class=\"gb-element-3a0a1875\">\n<div><div class=\"gb-looper-85239282\">\n<div class=\"gb-loop-item gb-loop-item-4e490d8e post-26980 post type-post status-publish format-standard has-post-thumbnail hentry category-mobility resize-featured-image\">\n<h3 class=\"gb-text gb-text-d038d18d\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/what-many-people-install-to-protect-their-cars-can-now-result-in-fines-of-1000-or-even-arrests\/26980\/\">What many people install to protect their cars can now result in fines of $1,000 or even arrests<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>If everything works, life inside domes and underground habitats might feel a bit like living in an ultra-efficient building during a very long winter, one where opening the window is never an option. If something breaks, there is no backup grid and no nearby farm to lean on. That reality has pushed some engineers to argue that Mars could become the ultimate test bed for circular economy technologies that we also need on Earth from advanced water recycling to low-energy food production in harsh climates.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Two planets sharing one environmental bill<\/h2>\n\n\n\n<p>All of this also has an environmental price here at home. Building hundreds or even thousands of giant rockets requires mining and shaping huge quantities of metal, running energy hungry factories and operating sprawling launch sites. <\/p>\n\n\n\n<p>A recent life cycle assessment of launch <a href=\"https:\/\/arxiv.org\/abs\/2504.15291\" target=\"_blank\" rel=\"noopener\">systems<\/a> estimated that building and firing rockets and satellites is responsible for most of the space sector\u2019s greenhouse <a href=\"https:\/\/www.ecoticias.com\/en\/more-than-a-million-fragments-orbit-the-earth-and-the-esa-warns-that-the-problem-of-space-debris-is-getting-worse\/24929\/\">gas emissions<\/a>, although reusable vehicles such as Starship could cut manufacturing related emissions by more than 90 percent compared to expendable rockets.<\/p>\n\n\n\n<div class=\"gb-element-dac9a45f\">\n<div><div class=\"gb-looper-ef008bd9\">\n<div class=\"gb-loop-item gb-loop-item-b2f49b70 post-26986 post type-post status-publish format-standard has-post-thumbnail hentry category-environment resize-featured-image\">\n<h3 class=\"gb-text gb-text-2803c559\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/a-giant-tortoise-extinct-for-over-a-century-has-reappeared-alive-after-several-failed-expeditions-reviving-a-historic-plan-to-save-the-species-a-symbol-of-evolution\/26986\/\">A giant tortoise, extinct for over a century, has reappeared alive after several failed expeditions, reviving a historic plan to save the species, a symbol of evolution<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>Right now rocket launches still account for far less than one tenth of one percent of global carbon dioxide emissions. Yet scientists warn that soot and other particles injected high in the atmosphere during <a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2021EF002612\" target=\"_blank\" rel=\"noopener\">launch and reentry <\/a>can have an outsized warming effect and may damage the ozone layer as launch numbers rise.<\/p>\n\n\n\n<p>Critics look at those trends and ask a simple question. At a time when just a few dozen fossil fuel <a href=\"https:\/\/influencemap.org\/briefing\/The-Carbon-Majors-Database-2023-Update-31397\" target=\"_blank\" rel=\"noopener\">companies are still responsible <\/a>for roughly half of global carbon emissions, is it wise to pour vast resources into a Mars lifeboat rather than cutting pollution at the source here on Earth.<\/p>\n\n\n\n<p>Supporters answer that the same technologies needed for a Mars city can push cleaner energy, better recycling and more efficient industry on our own planet. Both views can be true to a large extent.<\/p>\n\n\n\n<p>In the end Musk\u2019s Mars plan forces a reframing of sustainability. On Mars it means learning to live within a tiny, fragile bubble in a hostile environment. On Earth it still means keeping the one big bubble we already have in stable shape.&nbsp;<\/p>\n\n\n\n<p>The official statement was published by <a href=\"https:\/\/www.spacex.com\/humanspaceflight\/mars\" target=\"_blank\" rel=\"noopener\"><em>SpaceX<\/em><\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At the entrance to Starbase in south Texas, a glowing sign now welcomes visitors with the words \u201cGateway to Mars.\u201d &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"Elon Musk reveals his most ambitious (and detailed) plan for Mars: 1,000 spacecraft, 20 years of launches, and a self-sustaining city of one million inhabitants on Mars by 2050\" class=\"read-more button\" href=\"https:\/\/www.ecoticias.com\/en\/elon-musk-reveals-his-most-ambitious-and-detailed-plan-for-mars-1000-spacecraft-20-years-of-launches-and-a-self-sustaining-city-of-one-million-inhabitants-on-mars-by-2050\/27121\/#more-27121\" aria-label=\"Read more about Elon Musk reveals his most ambitious (and detailed) plan for Mars: 1,000 spacecraft, 20 years of launches, and a self-sustaining city of one million inhabitants on Mars by 2050\">Read more<\/a><\/p>\n","protected":false},"author":15,"featured_media":27123,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[],"class_list":["post-27121","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technology","resize-featured-image"],"_links":{"self":[{"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/posts\/27121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/users\/15"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/comments?post=27121"}],"version-history":[{"count":2,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/posts\/27121\/revisions"}],"predecessor-version":[{"id":27369,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/posts\/27121\/revisions\/27369"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/media\/27123"}],"wp:attachment":[{"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/media?parent=27121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/categories?post=27121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ecoticias.com\/en\/wp-json\/wp\/v2\/tags?post=27121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
