Former Karnataka Chief Minister HD Kumaraswamy held PM Narendra Modi responsible after Chandrayaan-2's Vikram lander lost contact with the ground station. "PM came to Bengaluru to give a message that he himself was landing Chandrayaan-2...he came just for sake of advertisement," he said. "Once he stepped in the ISRO Centre, I think it became bad luck for scientists," Kumaraswamy added.
