CHANDRAYAAN-2 BOILS DOWN TO 15 ‘TERRIFYING’ MINS – THESE 15 MINUTES ARE GOING TO BE THE MOST TERRIFYING FOR ALL OF US
CHANDRAYAAN LAUNCHING ON JULY 15TH AND LANDING ON SEPTEMBER 6 OR 7
“Braking the speed of the lander 30 km above till landing on the surface will take about 15 minutes. These 15 minutes are going to be the most terrifying for all of us,”
Bengaluru . Briefing by Dr. K Sivan, Chairman, ISRO A Press Meet was organized today, June 12, 2019 at ISRO Headquarters, Bengaluru on the occasion of the forthcoming launch of India’s Chandrayaan-2 mission to Moon. Dr K Sivan, Chairman, ISRO addressed and interacted with over hundred and fifty regional, national and international media persons during the meet. Dr Sivan outlined ISRO’s vision on space science and interplanetary missions. Understanding the secrets of the inner solar system is an aspiration of both national and international scientific community. Specifically talking about Chandrayaan-2, he announced “The launch of Chandrayaan-2 onboard GSLV MkIII-M1 is planned on July 15, 2019 at 02.51 Hrs from Sriharikota”. Further, he said the soft landing of the Vikram lander of Chandrayaan-2 on the Moon’s surface is likely to be on September 06, 2019. The briefing included the scientific objectives, challenges and benefits of the mission. He also provided details on the orbiter, lander and rover as well as the challenging tasks of navigating to the Moon and inserting the spacecraft into lunar orbit.
chandrayaan-2 will boil down to 15 ‘terrifying’ mins Isro personnel busy undertake the final stage of checking of the orbiter and lander of Chandrayaan-2 at the Isro satellite integration and testing establishment in Bengaluru on Wednesday. dh photo/Krishnakumar P S Years of planning, design of cutting-edge technology and expectations of a billion people on Chandrayaan-2 will ultimately boil down to 15 minutes on September 6 or 7. According to Isro chairman R Sivan, these 15 minutes on D-day will be the “most terrifying” for all the personnel involved in the mission as it will determine whether the mission is a success or failure. When the lander Vikram is about 30 km from the lunar surface, the real event will happen – the D-day. The propulsion system of the lander is going to function and it will break down the velocity of the lander in a controlled fashion near South Pole, Sivan said. “Braking the speed of the lander 30 km above till landing on the surface will take about 15 minutes. These 15 minutes are going to be the most terrifying for all of us,” Sivan said. The successful landing of Vikram will be an unprecedented event in the history of Isro as the space agency has not undertaken such a complex flight before. Once the lander lands near two craters near the lunar South Pole, the rover Pragyan will inch outside the lander. Pragyan will travel at a speed of 1 cm/sec or about 36 metres per hour conducting tests and relaying vital information to ground control. Isro expects the rover to move about 500 m from the landing site. The insignia of Ashok Chakra is imprinted on one of its wheels and Isro logo on the other. One of the reasons Isro selected the spot for landing is that the region has less number of craters and boulders. Apart from it, Isro hopes to find more water and minerals near the South Pole. How soon for pictures? Instruments aboard the orbiter and lander will ensure a steady stream of images this time. How quickly will Isro receive these images? The orbiter will beam the first pictures of landing within a few seconds. However, pictures clicked by the rover will take four hours for transmission, he added
Dr Sivan then specially mentioned about the highly demanding task of soft landing on the lunar surface and termed it as “15 terrifying minutes” Earlier during the day, the media persons had anopportunity to view Chandrayaan2 orbiter and lander at ISRO Satellite Integration and Test Establishment (ISITE), Bengaluru. The briefing by Chairman, ISRO was followed by an extensive interactive session with the media.
