43 years ago ISRO launched 1 rocket in 3 years, now we'll soon launch 50 per year: ISRO chief

ISRO chief Dr V Narayanan said, "When I joined ISRO 43 years ago, one launch used to take place once every three years." Speaking about the achievements, Narayanan added, "It is going to become a reality – 50 launches per year is going to be a reality, perhaps within a couple of years."
