How Chandrayaan-2 will reduce speed from 21,600 kmph to 7 kmph for soft landing
India TodayThe intervening night of Friday and Saturday is going to be an anxious one for not only the scientists of the Indians Space Research Organisation and people in the Narendra Modi government but for many others - who have been following the flight of Chandrayaan-2 from Sriharikota in Andhra Pradesh on July 22. In simple terms, soft landing is the descent of a lander at a reduced speed of around 7 kmph or 2 metres per second. The lander of Chandrayaan-2 is named Vikram after Dr Vikram A Sarabhai, the father of the Indian space programme | Screenshot form an Isro video The Chandrayaan-2 lander needs to reduce its descent speed from 21,600 kmph to 7 kmph and it has all of just 15 minutes to do so else it wouldn't be soft landing. Lander Vikram is designed to execute a soft landing on the lunar surface | Screenshot form an Isro video With speed reduced to around 7 kmph, Vikram will do another crucial examination of the Moon's surface from a distance of about 100 metres to make a safe, scratch-free landing. The four legs of Vikram are strong and flexible enough to safely absorb an impact exerted by landing on the Moon's surface at a speed of 18 kmph or 5 metres per second.
