Sriharikota: The historic launch of #Chandrayaan2 was called off today after a technical snag was observed in launch vehicle system, 1 hour before the launch.

An ISRO tweet at about 3.30 am on Monday 15 July 2019 announced “as a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later.”

At 1.30 am, ISRO had made the announcement: “1 hour to go! #Chandrayaan2 #GSLVMkIII #ISRO
Watch the live telecast from 2:30 AM IST on our website https://bit.ly/2LTTdrp and on DD National”.

Dr K Sivan, Chairman, ISRO had addressed and briefed over 150 regional, national and international media persons about India’s Chandrayaan-2 mission to Moon this past Friday, 12 June 2019, at ISRO Headquarters,Bengaluru.

Dr Sivan had 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, he had observed. Specifically talking about Chandrayaan-2, he had announced “The launch of Chandrayaan-2 onboard GSLV MkIII-M1 planned for Monday (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 6 September 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. 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 that day, the media persons had an opportunity to view Chandrayaan-2 orbiter and lander at ISRO Satellite Integration and Test Establishment (ISITE) at Bengaluru.

Chandrayaan-2, according to ISRO, is designed to soft land the lander -Vikram and rover- Pragyan in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70° south. Evidence for water molecules discovered by Chandrayaan-1, requires further studies on the extent of water molecule distribution on the surface, below the surface and in the tenuous lunar exosphere to address the origin of water on Moon. Moreoever, extensive mapping of lunar surface to study variations in lunar surface composition is essential to trace back the origin and evolution of the Moon. Significantly, Moon provides the best linkage to Earth’s early history. It offers an undisturbed historical record of the inner Solar system environment. Though there are a few mature models, the origin of Moon still needs further explanations. The lunar South Pole is especially interesting because of the lunar surface area here that remains in shadow is much larger than that at the North Pole. There is a possibility of the presence of water in permanently shadowed areas around it. In addition, South Pole region has craters that are cold traps and contain a fossil record of the early Solar System.
