चंद्रयान-2 चंद्रमा की सतह पर 7 सितंबर को करेगा ‘सॉफ्ट लैंडिंग’

चंद्रयान-2 के लैंडर ”विक्रम” को निचली कक्षा में लाने के बाद यह चंद्रमा के और नजदीक पंहुच गया, जहां से यह अंतत: नीचे की ओर आगे बढ़ते हुए 7 सितंबर को चंद्रमा की सतह पर ऐतिहासिक ‘सॉफ्ट लैंडिंग’ करेगा.

चंद्रमा की सतह पर ‘चंद्रयान-2’ के उतरने का सीधा नजारा देखने के लिए प्रधानमंत्री नरेंद्र मोदी बेंगलुरु स्थित इसरो केंद्र में मौजूद रहेंगे.

‘चंद्रयान-2’ के चांद पर उतरने के साथ ही रूस, अमेरिका और चीन के बाद भारत वहां ‘सॉफ्ट लैंडिंग करने वाला दुनिया का चौथा और चंद्रमा के अनदेखे दक्षिणी ध्रुव क्षेत्र में उतरने वाला दुनिया का पहला देश बन जाएगा.

India’s lunar mission to land on the moon in wee hours tomorrow

India is on the verge of creating history as the national space agency, ISRO(Indian Space Research Organisation), is all geared up to navigate the lander of Chandrayaan-2 to soft-land on the moon. This will be the first-ever moon landing for any Indian Spacecraft.

The crucial landing operation would be held between 1 and 2 am on Saturday, using the most complex ‘powered descent’ of the Lander Vikram. After initiating the powered descent, the Lander is expected to touch down gently on the lunar South Pole in just fifteen minutes, as informed by the ISRO Chairman Dr K Sivan.

The powered descent is being attempted for the first time by the ISRO. It involves several novelties. Scientists say, the Lander is equipped with five thrusters to slow it down during its downward movement towards the moon surface and balance the Lander in such a way that it touches down properly without rattling the dusty ground. The speed of the downward movement of the Lander is expected to be just under two metres a second.

The Lander is primed to release the rover it carries after whatever dust raised from the surface is settled. It is expected to take about four hours before the rover rolls out by using a ramp that will emerge from of the Lander. The Rover is named Pragyaan, meaning wisdom, which is expected to send huge data useful to expand the understanding of the moon, along with the observations of the Orbiter and the Lander.

Scientists say, during the soft-landing process, the Lander Vikram scans the lunar surface. Its inbuilt autonomous features help choose the right place to set its feet on. Space scientists say, human control at that stage may not be preferable, one reason is that there would be a time lag between the back and forth communication between the earth station and the lunar craft, that are separated by a distance of more than 3.8 lakh kilometres.

Several earth-based landing trials have been made even before the launch of the mission, in addition to the simulation tests, boosting the confidence of the scientists in the complex endeavour. Over a billion Indians are awaiting the consummation of the mission Chandrayaan-2 with bated breath, as the ISRO scientists are confidently moving ahead with the operation.

Prime Minister Narendra Modi is scheduled to reach Bengaluru tonight and witness the soft-landing of Chandrayaan-2 lander on the moon. He will be joined by about seventy high school students from across the nation, who have qualified to accompany him by way of winning in a national quiz about the ambitious mission.

ISRO Scientists keeping a close eye on the descent of lander Vikram

In the Satellite Control Centre of the Indian Space Research Organisation(ISRO) Telemetry, Tracking and Command Network in Bengaluru, the scientists are actively involved in the landing manoeuvre of Chandrayaan-2. The Lander Vikram is now at the most favourable path around the moon.

The scientists and engineers are confidently moving ahead with the most important task, with the self-assurance they have gained through the earth-based trials and simulation tests. Confidence is writ large on their faces and are all geared up to n avigate Chandrayaan-2 to reach its summit, the lunar South Pole.

Over 1.2 billion people pray for the success of India’s first moon landing

As India’s ambitious Lunar mission takes its final leap in about 12 hours from now, over 1.2 billion people pray for the success of the first moon landing. Meanwhile, over seventy students have been selected from across the country to witness the historic moment along with the Prime Minister at ISRO.
