It uses nulling interferometry in the x-Array configuration with four light collecting spacecraft and one beam combiner to detect distant exoplanets. The baseline must be 20-150 km to obtain angular resolutions of 30-200 \u00b5as in order to observe exoplanet&#8217;s atmosphere composition, detecting H2O, O3, CH4 and CO2 signatures in mid-IR (6-20 \u00b5m) spectrum. Solar sailing is used to reach 550-800 AU, where gravitational lensing takes place. The mission launch date is estimated to be around 2050 with the spacecraft reaching cruise speeds of 15-41 AU\/yr with a payload mass of 2-3 tonnes.<\/p>\n","protected":false},"featured_media":10372,"template":"","meta":{"_members_access_role":[],"_members_access_error":""},"pwb-brand":[],"product_brand":[],"product_cat":[56,59,166],"product_tag":[2185,584,3305,1170],"class_list":["post-10370","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2016papers","product_tag-exoplanet","product_tag-gravitational-lens","product_tag-nulling-interferometry","product_tag-solar-sail","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\/10370","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\/10372"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=10370"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=10370"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=10370"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=10370"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=10370"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
