The approach velocity had to be just right and the altitude\nover the moon rather precise. Even a small error would have killed the mission.<\/p>\n\n\n\n
“Our hearts stopped for 30 minutes till the job was\ndone… Three more manoeuvres are to be completed. The next is tomorrow around\n1 pm. The big event is on September 2 when the lander will be separated,”\na visibly excited ISRO Chairman K Sivan told reporters.<\/p>\n\n\n\n
“Following this, a series of orbit manoeuvres will be\nperformed on Chandrayaan 2 spacecraft to enable it to enter its final orbit\npassing over the lunar poles at a distance of about 100 km from the moon’s\nsurface,” the Indian Space Research Organisation said in a post on its\nwebsite.<\/p>\n\n\n\n
“Subsequently, the lander will separate from the\norbiter and enter into a 100 km x 30 km orbit around the moon. Then, it will\nperform a series of complex braking manoeuvres to soft land in the south polar\nregion of the moon on September 7, 2019,” ISRO said.<\/p>\n\n\n\n
The process of landing Chandrayaan 2 on the moon is very\ncomplex since it blasted off at a velocity of 39,240 kilometres per hour, which\nis almost 30 times the speed at which sound travels through air.<\/p>\n\n\n\n
The former director of the ISRO satellite centre M\nAnnadurai, who was the head of India’s first moon mission Chandrayaan 1,\ndescribed the complexity of the operation: “It is like a gentleman with a\nrose in hand proposing to a lady who is dancing at a stunning speed of 3,600\nkilometres per hour (almost five times the speed of an airplane), and not next\ndoor, but at a distance of 3.84 lakh kilometres away. If the couple have to\nmeet, then the precision and accuracy is of utmost importance.”<\/p>\n\n\n\n
India’s most ambitious space mission to date, Chandrayaan 2\nhad lifted off from the spaceport at Sriharikota in Andhra Pradesh on July 22.\nThe lift-off was successful in its second attempt, a week after it was aborted\njust under an hour from its launch due to a technical glitch.<\/p>\n\n\n\n
The mission stands out because of its low cost, with just\nabout Rs. 1,000 crore spent – a much smaller price tag compared to similar\nmissions by other countries.<\/p>\n\n\n\n
If successful, the mission will make India the fourth\ncountry to soft land a rover on the lunar surface after Russia, US and China.\nThe last nation to attempt a soft landing on the moon, Israel, failed in its\nmission earlier this year.<\/p>\n\n\n\n
After shooting off into space, the spacecraft’s orbit was\n“progressively increased five times” between July 23 and August 6. It\nwas then flung towards the moon, at a distance of 3.84 lakh kilometres away.<\/p>\n","protected":false},"excerpt":{"rendered":"
Chandrayaan 2 has been successfully manoeuvred into lunar orbit on 20 August, after nearly 30 days of space travel. This was one of the trickiest operations in the mission.
