The landing of Chandryaan-2 would have made India the fourth country in the world to successfully land a spacecraft intact on the moon after US, Russia and China but unfortunately after covering a distance of 3.844 lakh Km between the Earth and the Moon, Chandrayaan-2’s landing failed when it was at a distance of 2.1 Km from the surface of the Moon. The landing was supposed to be India’s first soft landing on the Moon with the country’s robotic ‘Vikram’ lander engineered to land on the surface of Moon carrying the “Pragyan” rover. According to Indian Space Research Organisation (ISRO), Chandrayaan-2 mission was a highly complex mission, which represented a significant technological leap compared to the previous missions of ISRO, which brought together an Orbiter, Lander and Rover to explore the unexplored south pole of the Moon. The Vikram lander was a critical part of India’s Chandrayaan-2 mission. Vikram was carrying a rover called Pragyan, and together the two vehicles were meant to explore the south pole region in up-close detail using a series of instruments, including a seismometer to measure lunar quakes and X-rays to help figure out the composition of the dirt (and potential water ice). But just a few minutes before Vikram was scheduled to touch down on the Moon, data of the lander from inside India’s mission control center showed the vehicle to be slightly off course. When Vikram was about 1.3 miles (2.1 kilometers) above the surface, India lost communication with the lander. India has yet to give official confirmation on whether or not the lander did, indeed, crash. Did Vikram lander crash on to the Lunar Surface? Reliable sources in ISRO agreed that there is a possibility that the Chandryaan-2 lander Vikram crashed on to the lunar surface resulting in the sudden snapping of the communication link with the Chandrayaan-2 orbiter. Sources in Isro said that Vikram deviated from its path at an altitude of 2.1 km from its designated landing spot on the Moon’s South Pole. After that, the lander reached 335 meters at a speed of 60 meters per second. It was at this place that Vikram lost contact with the Isro station in Bengaluru.

ISRO is now analyzing the data of Vikram’s flight to find out why it lost its way at an altitude of 2.1 Km. Scientists said they suspect that Vikram hit the Moon’s surface at the same speed with which it was coming down. Since the lander is intermittently connecting with the orbiter, Isro scientists are still hopeful that the lander will be able to establish communication. ISRO revealed that they are going to try to re-establish communication with the lander for the next 14-days and will also try to get images of the lander with the help of a high definition camera installed in the orbiter. However, it will take some time for the orbiter to enter the orbit in front of the lander, as the lander and orbiter were circling in different orbits. The only thing now on which the fate of the lander and rover depends is ‘hope’. We are keeping our fingers crossed and hopes high that the Vikram rover still might re-establish communication with the base.

एजेन्सी। भारतीय अन्तरिक्ष अनुसन्धान केन्द्र (इसरो) ले चन्द्रयान–२ को ल्यान्डर विक्रम पत्ता लगाउन सफल भएको छ । इसरोका अध्यक्ष डा के सिवनले चन्द्रमामा विक्रम ल्यान्डर पत्ता लागिसकेको बताए । अर्बिटरले ल्यान्डरका केही तस्वीरहरू लिएको छ । विक्रमसँग सम्पर्क गर्ने कोशिश जारी छ । अर्बिटरले खिचेको ल्यान्डरको तस्वीर इसरोसम्म पुगेको भने छैन । शनिवार बिहान अन्तरिक्ष विज्ञानमा भारतले इतिहास रच्न लागेको थियो तर चन्द्रयान–२ को ल्यान्डर विक्रम ल्यान्डिङको हुनुभन्दा जम्मा ६९ सेकेन्डअघि पृथ्वीसँग सम्पर्क टुटेको थियो । सिवनले भारतीय मिसन ९९ प्रतिशत सफल भएको अनि अन्तिम चरणमा ल्यान्डरसँग सम्पर्क टुटेको बताए। सिवनले भनेका थिए, ‘ल्यान्डर विक्रमको अवतरण प्रक्रिया एकदम सही थियो । चन्द्रमाको दक्षिणी ध्रुवको सतहभन्दा जम्मा २.१ किलोमिटर टाढा हुँदा पृथ्वीसँग सम्पर्क टुट्यो । हामीहरू अर्बिटरबाट प्राप्त डेटाको विश्लेषण गरिरहेका छौं । आगामी १४ दिन सम्पर्क कायम गर्ने कोशिश गर्नेछौं ।’ जुन अर्बिटरबाट ल्यान्डर अलग्गिएको थियो, त्यो अहिले पनि चन्द्रमाको सतहबाट ११९ किलोमिटरदेखि १२७ किलोमिटरको उचाइमा घुमिरहेको छ । कुल २३ सय ७९ किलो तौल भएको अर्बिटरसँग ८ पेलोड छ र यसले ७ वर्षसम्म काम गर्नेछ। अमेरिकी अन्तरिक्ष एजेन्सी नासाले विगत ६ दशकमा चन्द्रमामा पठाइएकोमध्ये ६१ प्रतिशत मिसन मात्र सफल भएको बताएको छ । सन् १९५८ देखि अहिलेसम्म् १०९ वटा मिसन चन्द्रमामा पठाइएकोमा ६० मिसन मात्र सफल भए । चन्द्र मिसनको पहिलो सफलता रुसले सन् १९५९ मा हासिल गरेको थियो ।
