A. Minovitch. (1991),\u00a0<em>JBIS<\/em>, 44, pp.589-597<\/h3>\n<p><strong>Refcode:\u00a0<\/strong>1991.44.589<\/p>\n<p><strong>Abstract:<\/strong><\/p>\n<p>The technical innovation of gravity-propelled interplanetary space travel (also known as &#8220;gravity-assisted&#8221; trajectories) was important because it opened the entire Solar System to exploration using relatively small launch vehicles with conventional chemical upper stages [1]. Moreover, it enabled one instrumented spacecraft to explore many planets in a single mission, essentially without using any rocket propulsion after the initial injection from Earth. The Mariner IO Eartl1-Venus-Mercury, the Pioneer 10 and 11, the Voyager 1 and 2, the low launch energy Galileo mission to Jupiter, and the Ulysses mission to the Sun out-of-the-ecliptic plane were made possible by this innovation. These missions clearly demonstrate the economics of utilising the concept. of gravity propulsion to achieve multiplanetary exploration with a single spacecraft launched by a single launch vehicle. But there are some limitations. For example, due to the relative positions of Neptune and Pluto, it was not possible to redirect Voyager 2 to Pluto after the Neptune encounter via gravity propulsion. Thus, NASA is planning a special mission to that planet.<\/p>\n","protected":false},"featured_media":12204,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,3591],"product_tag":[],"class_list":["post-12203","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-jbis-1991","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\/12203","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\/12204"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=12203"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=12203"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=12203"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=12203"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=12203"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
