The spacecraft consists of an orbiter, a lander and a rover, and the mission aims to study the thickness and sub-layer distribution of the Martian soil.<\/p>\n<p>The spacecraft, weighing 5 tonnes, launched on a Long March 5 rocket from Xichang, China. The scientific goals of the mission include studying Martian topography and geology and determining the composition of the surface material, climate and environment.<\/p>\n<p><strong>Tianwen-1 will reach the Red Planet\u2019s orbit in February 2021. The rover will land on Mars.<\/strong><\/p>\n<p>The orbiter will use high-resolution cameras to search for a suitable landing site somewhere in the Utopia Planitia region. It weighs around 240 kg and will carry cameras, a subsurface radar, a spectrometer, a magnetometer, and atmospheric sensors.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_US_mission\"><\/span><span style=\"color: #ff0000;\">The US mission<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>NASA\u2019s newest rover Perseverance \u2014 other rovers have landed on Mars earlier \u2014 will look for signs of habitable conditions on Mars and microbial life in its ancient past. Over its mission duration of one Martian year (687 Earth days), it will collect Martian rock and sediment samples for analysis on Earth.<\/p>\n<p>The rover is equipped with specialised equipment to collect data, analyse weather conditions that can help plan for future human missions, and produce oxygen from the carbon-dioxide-rich atmosphere.<\/p>\n<p>Perseverance is expected to touch down on Mars on February 18, 2021. NASA\u2019s Curiosity rover has been exploring Mars since 2012. It remains active although its targeted mission life is over.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_space_race\"><\/span><span style=\"color: #ff0000;\">The space race<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Space exploration has been dominated by the US and Russia for more than 50 years. \u201cChina joining (the Mars race) will change the situation dominated by the US for half a century,\u201d the news agency AFP quoted Chen Lan, an independent analyst at GoTaikonauts, which specialises in China\u2019s space programme, as saying.<\/p>\n<p>China sent a human into space in 2003. It has also started plans to set up a space station by 2022. China has also sent two rovers to the Moon, with the second landing on the far side.<\/p>\n<p>Mars is a bigger challenge, however. As McDowell told AFP, the much greater distance means \u201ca bigger light travel time, so you have to do things more slowly as the radio signal round trip time is large\u201d. It also means \u201cyou need a more sensitive ground station on Earth because the signals will be much fainter\u201d.<\/p>\n<p><strong>China, in partnership with Russia, had attempted a mission to Mars in 2011 too, but the launch failed.<\/strong><\/p>\n<p>Chinese mission\u2019s spokesman, Liu Tongjie, has been quoted as saying: \u201cWe carry out this first Mars exploration mission to peacefully use the universe and to explore its mysteries. It\u2019s for this purpose. It\u2019s not to launch a competition with any other country.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #0000ff;\"><strong>For more such notes, Articles, News &amp; Views Join our Telegram Channel.<\/strong><\/span><\/p>\n<p><a title=\"Telegram Link\" href=\"https:\/\/t.me\/triumphias\" target=\"_blank\"><span style=\"color: #ff0000;\"><strong>https:\/\/t.me\/triumphias<\/strong><\/span><\/a><\/p>\n<p><span style=\"color: #0000ff;\"><strong>Click the link below to see the details about the UPSC \u2013Civils courses offered by Triumph IAS.<\/strong> <\/span><span style=\"color: #ff0000;\"><strong><a style=\"color: #ff0000;\" title=\"Courses available\" href=\"https:\/\/triumphias.com\/pages-all-courses.php\">https:\/\/triumphias.com\/pages-all-courses.php<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Relevance: Prelims\/Mains: G.S paper III: Science and technology Context: China Mars mission Tianwen-1: The spacecraft consists of an orbiter, a<\/p>\n","protected":false},"author":1,"featured_media":3522,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[123],"tags":[392],"class_list":["post-9211","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-current-affairs","tag-union-public-service-commission-upsc"],"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/9211","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/comments?post=9211"}],"version-history":[{"count":1,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/9211\/revisions"}],"predecessor-version":[{"id":9212,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/9211\/revisions\/9212"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media\/3522"}],"wp:attachment":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media?parent=9211"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/categories?post=9211"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/tags?post=9211"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
