It is the Solar Gravitational Lens (SGL): the gravitational field of the Sun, which has the ability to bend and focus light similar to a lens. In the foreseeable future, a small telescope (1-2 m) could operate on the focal line of the SGL at distances between 600-800 astronomical units (AU) from the Sun, to provide high-resolution images of a distant exoplanet. This instrument could deliver thousand-by-thousand-pixel images of &#8220;Earth 2.0&#8221; at distances of up to 100 light years (ly) and with a spatial resolution of ~10 km on its surface&#8211;sufficient to discern surface features such as continents. Although theoretically feasible, the engineering aspects of building an astronomical telescope that is designed to operate at such a large distance from Earth have not been addressed before. &#8211; The question of getting there and the issues of operating a spacecraft at such enormous distances with the required precision will be addressed. Aspects of concept design and spacecraft requirements for a mission to the distant regions of the outer solar system will be discussed. This step is a necessary precursor to any future robotic missions to another star.<\/p>\n","protected":false},"featured_media":10529,"template":"","meta":{"_members_access_role":[],"_members_access_error":""},"pwb-brand":[],"product_brand":[],"product_cat":[56,59,168],"product_tag":[3417,3416],"class_list":["post-10527","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2018papers","product_tag-direct-imaging-of-exoplanets","product_tag-solar-gravitational-lens","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\/10527","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\/10529"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=10527"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=10527"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=10527"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=10527"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=10527"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
