ISRO Statistics By Patents And Facts (2025)

Introduction

ISRO Statistics: In today’s world, space technology is quickly changing how we connect, protect, and study our planet. One name that’s making headlines around the globe is ISRO (Indian Space Research Organization). Known for its low-cost yet powerful space missions, ISRO has proven that you don’t need to spend billions to achieve big goals.

In 2024, ISRO continued to break records with new satellite launches, deep-space missions, and innovative partnerships. This topic matters because ISRO is helping make space more affordable and open to all, not just wealthy nations. In this article, ISRO Statistics, we’ll look at ISRO’s latest launch data, budget numbers, major missions, business deals, and its growing global role in the space industry.
