As the countdown for Chandrayaan-3, India's third lunar exploration mission began around 1.05 pm on Thursday, July 13, more than 17,000 employees of the Indian Space Research Organisation waited eagerly with bated breath and nervous anticipation.
Chandrayaan-3 is the third instalment of the Chandrayaan series and India's second attempt to achieve a soft landing on the moon's surface.
Only three countries (United States, Russia and China) have successfully landed spacecraft on the airless lunar surface.
