In an anti-climax of sorts, Chandrayaan 2, India's second mission to the moon, was called off after the Indian Space Research Organisation (ISRO) encountered a technical snag. "A technical snag was observed in launch vehicle system at 1 hour before the launch. As a measure of abundant precaution, #Chandrayaan2 launch has been called off for today. Revised launch date will be announced later," ISRO tweeted.
