Through this effort, the aim is\nto improve our understanding of the Moon, discoveries that will benefit India\nand humanity as a whole. These insights and experiences aim at a paradigm shift\nin how lunar expeditions are approached for years to come propelling further\nvoyages into the farthest frontiers.<\/p>\n\n\n\n<p><strong>Why\nChandrayaan 2?<\/strong><\/p>\n\n\n\n<p>The Moon is the\nclosest cosmic body at which space discovery can be attempted and documented.\nIt is also a promising test bed to demonstrate technologies required for\ndeep-space missions. Chandrayaan 2 attempts to foster a new age of discovery,\nincrease our understanding of space, stimulate the advancement of technology,\npromote global alliances, and inspire a future generation of explorers and\nscientists.<\/p>\n\n\n\n<p><strong>Objective\nof Chandrayaan 2:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Moon provides the best linkage to\nEarth\u2019s early history. It offers an undisturbed historical record of the inner\nSolar system environment. <\/li><li>Though there are a few mature models,\nthe origin of Moon still needs further explanations. Extensive mapping of lunar\nsurface to study variations in lunar surface composition is essential to trace\nback the origin and evolution of the Moon. <\/li><li>Evidence for water molecules discovered\nby Chandrayaan-1, requires further studies on the extent of water molecule\ndistribution on the surface, below the surface and in the tenuous lunar\nexosphere to address the origin of water on Moon.<\/li><li>The lunar South Pole is especially\ninteresting because of the lunar surface area here that remains in shadow are\nmuch larger than that at the North Pole. There is a possibility of the presence\nof water in permanently shadowed areas around it. In addition, South Pole\nregion has craters that are cold traps and contain a fossil record of the early\nSolar System.<\/li><li>Chandrayaan-2 will attempt to soft land\nthe lander -Vikram and rover- Pragyan in a high plain between two craters,\nManzinus C and Simpelius N, at latitude of about 70\u00b0 south.<\/li><\/ul>\n\n\n\n<p><strong>Series\nof orbit manoeuvres:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Chandrayaan-2\nhad been orbiting the Earth, moving into higher and orbits. This is achieved by a series of Earth bound\nraising manoeuvres. There were five such manoeuvres\nbefore the mission left Earth orbit. From EPO (Earth Parking orbit) which is\n170 \u00d739120 km (The two figures refer to the distance at the nearest and\nfarthest points), the Chandrayaan 2 was raised in 5 successive orbits. <\/li><li>On August\n20, Chandrayaan-2 will approach Moon and the spacecraft\u2019s liquid engine will be\nfired again to insert the spacecraft into a lunar orbit. Following this, there\nwill be further four orbit manoeuvres to take the spacecraft into its final\norbit, passing over the lunar poles at a distance of about 100 km from the\nMoon\u2019s surface.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"241\" height=\"318\" src=\"https:\/\/i0.wp.com\/blogadmin.forumias.com\/wp-content\/uploads\/2019\/08\/f-2.jpg?resize=241%2C318&#038;ssl=1\" alt=\"\" class=\"wp-image-51281\"\/><\/figure>\n\n\n\n<p><strong>The Lander \u2013 Vikram:<\/strong><\/p>\n\n\n\n<p>The Lander of\nChandrayaan 2 is named&nbsp;Vikram&nbsp;after Dr Vikram A Sarabhai, the Father\nof the Indian Space Programme. It is designed to function for one lunar day,\nwhich is equivalent to about 14 Earth days.&nbsp;Vikram&nbsp;has the capability\nto communicate with IDSN at Byalalu near Bangalore, as well as with the Orbiter\nand Rover. The Lander is designed to execute a soft landing on the lunar\nsurface.<\/p>\n\n\n\n<p><strong>Rover\n\u2013 Pragyan:<\/strong><\/p>\n\n\n\n<p>Chandrayaan 2&#8217;s\nRover is a 6-wheeled robotic vehicle named&nbsp;Pragyan, which translates to\n&#8216;wisdom&#8217;&nbsp;in Sanskrit. It can travel up to 500 m (\u00bd-a-km) and leverages\nsolar energy for its functioning. It can only communicate with the Lander.<\/p>\n\n\n\n<p><strong>Chandrayaan\n1:<\/strong><\/p>\n\n\n\n<p>Chandrayaan-1, India&#8217;s first mission to Moon, was launched successfully\non October 22, 2008. The spacecraft was orbiting around the Moon at a height of\n100 km from the lunar surface for chemical, mineralogical and photo-geologic\nmapping of the Moon. The spacecraft carried&nbsp;11 scientific instruments\nbuilt in India, USA, UK, Germany, Sweden and Bulgaria.<\/p>\n\n\n\n<p><strong>Chandrayaan-1\nkey achievements:&nbsp;<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The Chandrayaan-1 discovered traces of\nwater on the moon-a path-breaking discovery in the world of space science. <\/li><li>Chandrayaan-1 also discovered water ice\nin the North Polar Region of the Moon. <\/li><li>It also detected Magnesium, Aluminium\nand Silicon on the lunar surface. <\/li><li>Global imaging of the moon is another\nachievement of this mission.<\/li><\/ul>\n\n\n\n<p><strong>Conclusion:\n<\/strong>With the entire scientific mission riding\non&nbsp;Chandrayaan-2, a successful landing near the South Pole in itself would\nbe a remarkable feat for ISRO as well as space exploration world over. One of\nNASA&#8217;s main priorities is to go to the South Pole on a sample return mission.\nSo findings from Chandrayaan 2 could help NASA, down-the-road, by providing the\nresults of what\u2019s all is there at Southern Polar Region of Moon.<\/p>\n\n\n\n<p><strong>Source:\n<\/strong><a href=\"https:\/\/indianexpress.com\/article\/explained\/isros-chandrayaan-2-reaches-key-stage-what-next-5908750\/\">https:\/\/indianexpress.com\/article\/explained\/isros-chandrayaan-2-reaches-key-stage-what-next-5908750\/<\/a><strong><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Context: Chandrayaan 2 will land on Moon\u2019s South Pole region.
