It consists of two\u00a0major components: the service module and the payload module.<\/li>\n<li>The\u00a0payload module comprises a\u00a01.2-m-diameter telescope and two scientific instruments:\u00a0a visible-wavelength camera (the VISible instrument, VIS) and a\u00a0near-infrared camera\/spectrometer (the Near-Infrared Spectrometer and Photometer, NISP).\u00a0<\/li>\n<li>The service module contains the satellite systems: electric power generation and distribution, attitude control, data processing electronics, propulsion, telecommand and telemetry, and thermal control.<\/li>\n<\/ul>\n<\/li>\n<li>Orbit: Its\u00a0operational orbit\u00a0will be halo around a point known as the Sun-Earth Lagrange Point 2 (L2), at an average distance of\u00a01.5 million km beyond Earth\u2019s orbit.<\/li>\n<li>Lifetime: Nominal mission lifetime is\u00a0six years, with the\u00a0possibility of extension (limited by the amount of cold gas used for propulsion).<\/li>\n<\/ul>\n<h2>What is Dark Energy?<\/h2>\n<ul>\n<li>\u00b7 Dark energy is the name given to the mysterious force that\u2019s causing the rate of expansion of our universe to accelerate over time rather than to slow down.\u00a0<\/li>\n<li>\u00b7 It is now thought to\u00a0make up\u00a068% of everything in the universe.<\/li>\n<li>\u00b7 It&#8217;s not matter or energy in the conventional sense. It\u00a0does not interact with electromagnetic forces and, therefore,\u00a0cannot be observed directly.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What is Dark Matter?<\/h3>\n<p>Dark matter is the mysterious stuff that fills the universe but no one has ever seen.Dark matter makes up over 80% of all matter in the universe.Dark matter is completely invisible. It emits no light or energy and thus cannot be detected by conventional sensors and detectors.\u00a0<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.space.com\/euclid-space-telescope-first-full-color-images-preview\" target=\"_blank\" rel=\"nofollow noopener\"><u>Dark matter-hunting Euclid mission to share its 1st full-color images of the universe on Nov. 7<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Euclid mission is part of ESA\u2019s Cosmic Vision programme which aims to explore the origin and components of the universe and the fundamental laws that govern it. <\/p>\n","protected":false},"author":5,"featured_media":16773,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-16772","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\/16772","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=16772"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/16772\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/16773"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=16772"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=16772"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=16772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
