While most teenagers are worrying about board exams, Advait S. is busy building "Rockoons"—a hybrid technology that uses high-altitude balloons to carry rockets into the stratosphere before ignition. By bypassing the thickest part of Earth’s atmosphere, his startup, Stellaris Space, can launch small satellites at a fraction of the cost of traditional ground-based rockets.

This "balloon-to-orbit" model isn't just a science project; it’s a serious deep-tech solution aimed at making space accessible for schools, researchers, and small startups. Advait, who taught himself complex aerospace engineering via the internet, has already gained attention from industry veterans for his "lean" approach to space exploration.

With India’s space sector opening up to private players, this young founder is proving that you don't need a billion-dollar pad to reach the stars—just a clever idea and a lot of helium. If Stellaris succeeds, the future of Indian space tech won't just be about massive boosters; it will be about the nimble, cost-effective innovations coming from the next generation of "garage" scientists. The sky isn't the limit; it's just the starting point!
