Opaque and transparent sunshades have been suggested for this application. Mass estimates are presented for both as well as a discussion of station-keeping issues. If constructed, such a megastructure would have additional applications. These include beaming energy to divert or destroy Earth-threatening Near Earth Asteroids (NEAS), space-based solar-energy production for terrestrial use, and energy beaming to accelerate laser-photon propelled starships engaged in interstellar migrations. Global warming may be a filter that an emerging galactic civilization might have to overcome. As such, technosignatures of extra-solar star-planet Lagrange sunshades might be detectable by extremely large telescopes. Larger Lagrange sunshades might also be constructed by a civilization inhabiting a planet circling an aging star since stellar luminosity increases with star age.<\/p>\n<p>Keywords: Lagrange Sunshade, Earth Defense, Space-Based Solar Energy, Interstellar Migration, Technosignatures<\/p>\n","protected":false},"featured_media":26970,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,3856],"product_tag":[],"class_list":["post-26968","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2023-papers","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/26968","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/26970"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=26968"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=26968"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=26968"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=26968"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=26968"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
