It offers high specific impulse and sustained acceleration, enabling efficient interplanetary travel with minimal fuel requirements.<\/p>\n<p><strong>Q2. <\/strong>What is the Sunbird nuclear fusion rocket?<br \/>\n<strong>Ans.<\/strong> The Sunbird is a nuclear fusion rocket concept developed by UK-based Pulsar Fusion. It integrates a Dual Direct Fusion Drive (DDFD) to provide both thrust and electrical power, potentially enabling missions to Pluto in just four years and halving travel time to Mars.<\/p>\n<p><strong>Q3. <\/strong>How does the Sunbird rocket achieve propulsion?<br \/>\n<strong>Ans.<\/strong> The Sunbird uses compact linear fusion reactors that generate plasma through nuclear fusion. The escaping particles from this plasma serve as exhaust, propelling the spacecraft. It also provides up to 2 MW of electrical power for payloads.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/indianexpress.com\/article\/technology\/science\/sunbird-nuclear-fusion-rocket-mars-time-half-pluto-4-years-9936341\/\" target=\"_blank\" rel=\"nofollow noopener\">IE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sunbird could potentially reach speeds of up to 805,000 km\/h, which is faster than the Parker Solar Probe (692,000 km\/h), currently the fastest human-made object.<\/p>\n","protected":false},"author":5,"featured_media":31914,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-31913","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31913","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=31913"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31913\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/31914"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=31913"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=31913"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=31913"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
