As humanity continues to expand its presence in space, the questions we\u2019re asking are also getting grander in scale. Here\u2019s an example: What if we could \u201cstop\u201d space weather?<\/p>\n

An ambitious proposal, published<\/a> earlier this month in Space Weather, explores the possibility of a space-based system designed to fortify Earth\u2019s natural defenses against damaging space weather, like solar storms. The system, dubbed \u201cStormWall,\u201d could use a constellation of spacecraft\u2014six in the example design\u2014to release material in geosynchronous orbit, where it would become plasma and drift toward the edge of Earth\u2019s magnetosphere. By seeding Earth\u2019s magnetosphere with plasma, the system would temporarily bolster its defenses against solar storms.<\/p>\n

\u201cWhen you apply some really serious physics to it, it does work. And the amount of mass we need, the launch capacities\u2014it\u2019s all within our capabilities,\u201d Brian Walsh, the study\u2019s first author and an engineer at Boston University, said in a statement<\/a>. \u201cPeople have always thought, \u2018space is huge, the sun is massive, we just have to sit here and take whatever it gives us.\u2019 But what we found is that we can impact it.\u201d<\/p>\n

Cosmic energy dump <\/p>\n

Geomagnetic storms occur when a \u201cvery efficient exchange of energy\u201d from the solar wind into the space around Earth creates a major disturbance in our planet\u2019s magnetosphere, according<\/a> to the Space Weather Prediction Center at the U.S. National Oceanic and Atmospheric Administration. While these intense currents create beautiful auroras, these disturbances can interfere with energy grids, satellites, and more.<\/p>\n

Meanwhile, previous research determined that this energy dump\u2014formally called magnetic reconnection\u2014depended on plasma density, magnetic field magnitude, and the orientation of both solar winds and the magnetosphere, the paper noted. Fascinatingly, simulations and spacecraft measurements strongly suggested that reconnection rates decreased with increased mass density in the magnetosphere.<\/p>\n

Suppressing the wind <\/p>\n

StormWall builds upon this idea of suppressing magnetic reconnection, somewhat like an \u201cautomobile airbag,\u201d as the study describes it. The system would start with several spacecraft fitted with mass-loading material in the form of alkaline chemicals like barium and lithium. When space weather forecasts solar storms, an operator on Earth releases the material from the canisters, which quickly becomes ionized and fortifies the magnetosphere\u2019s plasma.<\/p>\n

\u201cLong-term maintenance of the constellation is low, requiring only minimal upkeep and new launches only to replace spacecraft after mass release,\u201d the team noted in the paper. \u201cWhen needed, the constellation would provide powerful, on-demand protection against extreme storms.\u201d<\/p>\n

Are we really building a wall? <\/p>\n

Simulations of StormWall suggest the system could halve the impact of a major geomagnetic storm, the team reported in the study. Of course, the researchers also evaluated potential consequences of \u201cgeoengineering\u201d space. Although initial calculations indicate that solar wind would stave off the extraneous plasma, we\u2019ll need to probe this point further down the line, according to the paper.<\/p>\n

But the biggest challenge now is cost, Walsh said in the statement. Accordingly, the team\u2019s next steps will be to cut manufacturing costs and consider more efficient orbits, as well as which elements will be the most effective at decreasing magnetic reconnection. In any case, Walsh anticipates that, \u201cunlike some space missions that might reap rewards for the few, this one would benefit us all.\u201d<\/p>\n

\u201cIf you built it, if it was deployed, it would help all people on the planet,\u201d he said. \u201cYou couldn\u2019t make it in a way that helped only one country, one group of satellites.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"As humanity continues to expand its presence in space, the questions we\u2019re asking are also getting grander in…\n","protected":false},"author":2,"featured_media":528412,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[270],"tags":[18,69324,45490,19,17,133,451,14001],"class_list":["post-528411","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-eire","tag-geoengineering","tag-geomagnetic-storms","tag-ie","tag-ireland","tag-science","tag-space","tag-space-weather"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116726953453726271","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/528411","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=528411"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/528411\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/528412"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=528411"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=528411"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=528411"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
