LEV-1, LEV-2, and SLIM will together\u00a0study the lunar surface near the landing point, collect\u00a0temperature and radiation readings, and attempt to study the\u00a0moon\u2019s mantle.<\/li>\n<\/ul>\n<h2>Key points about XRISM Mission<\/h2>\n<ul>\n<li>The X-Ray Imaging and Spectroscopy Mission (XRISM) is a joint mission of the\u00a0Japan Aerospace Exploration Agency\u00a0(JAXA) and the\u00a0National Aeronautics and Space Administration\u00a0(NASA), involving contributions from the European Space Agency (ESA) and Canadian Space Agency as well.<\/li>\n<li>Objective: The mission aims to observe X-rays coming from deep space and to identify their wavelengths with unprecedented precision.<\/li>\n<li>It will use state-of-the-art spectroscopy to measure changes in the brightness of celestial objects at different wavelengths.\u00a0<\/li>\n<li>It detects X-rays with energies ranging from 400 to 12,000 electron volts. (For comparison, the energy of visible light is 2 to 3 electron volts.)<\/li>\n<li>This range will provide astrophysicists with new information about some of the universe&#8217;s hottest regions, largest structures, and objects with the strongest gravity.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What are X-rays ?<\/h3>\n<p>These are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/www.thehindu.com\/sci-tech\/science\/slim-pinpoint-lunar-landing-chandrayaan-4-isro-jaxa\/article67678970.ece\" target=\"_blank\" rel=\"nofollow noopener\"><u>How Japan\u2019s moon-landing attempt in January will affect Chandrayaan 4 | Explained<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Smart Lander for Investigating Moon (SLIM) spacecraft is a spacecraft built and launched by the Japan Aerospace Exploration Agency (JAXA) on September 7, 2023, from the Tanegashima spaceport.<\/p>\n","protected":false},"author":5,"featured_media":18714,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-18713","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\/18713","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=18713"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/18713\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/18714"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=18713"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=18713"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=18713"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
