Agnikul Cosmos nails 3D-printed rocket engine test, eyes reusable rockets

Technology Dec 19, 2025

Agnikul Cosmos, a Chennai-based space startup, just pulled off a successful 49-second test of its 3D-printed rocket engines—keeping things cool and steady the whole time.
Backed by ISRO and IN-SPACe, this marks a big leap for their Agnibaan rocket and India's homegrown space tech.

How they did it—and what's next

Their engines use electric pumps instead of old-school turbo-pumps, making them simpler and more precise.
Most parts were 3D-printed in-house to save time and money.
At the International Astronautical Congress in Sydney, Agnikul also revealed plans for a fully reusable launch vehicle (think SpaceX Falcon 9 vibes) and showed off patents from the US, Europe, and India—putting them firmly on the global space map.
