India has taken another step in private space innovation with the successful launch of Rhumi-1, the country’s first reusable mobile hybrid rocket. Developed by Chennai-based Space Zone India in collaboration with Martin Group, the rocket lifted off from a mobile launcher at Thiruvidandhai, a coastal village near Chennai, on August 24, 2024. The achievement positions India among the few nations advancing reusable space technology.
Weighing about 80 kilograms and standing 3.5 meters tall, Rhumi-1 is a sounding rocket designed to carry out suborbital experiments. On its maiden flight, it reached an altitude of 35 kilometers before returning safely to Earth within seconds. The mission deployed three CubeSats and 50 picosatellites, which will collect data on climate change and global warming.
Rhumi-1 runs on a hybrid propulsion system that combines a liquid oxidizer with solid fuel, a design that reduces costs while supporting reusability. Its mobile launch system also makes it unique, enabling flexible launches without fixed infrastructure. By comparison, SpaceX’s Starship uses liquid oxygen and methane, but Rhumi-1’s scale makes it better suited for educational and experimental purposes.
Space Zone India, founded by Anand Megalingam and led by Chairman K. Megalingam, aims to cut the financial burden of space exploration by creating environmentally friendly reusable rockets. The startup also focuses on engaging students and spreading awareness of rocket science.
Globally, Space Zone India becomes only the second company after SpaceX to demonstrate reusable rocket technology. While Rhumi-1 is far smaller than SpaceX’s Falcon 9 or Starship, its success marks the beginning of reusable rocket development in India and highlights the growing role of private startups in the country’s space sector.
