Context: Recently, India launched its first reusable hybrid rocket ‘RHUMI- 1’, developed by the Tamil Nadu-based start-up Space Zone India with Martin Group, from Thiruvidandhai in Chennai, with the goal of advancing research on global warming and climate change.

About ‘RHUMI-1’

• Rhumi-1 developed by the Tamil Nadu-based start-up Space Zone India.

• It is designed to revolutionize upper-stratospheric research.

• It is equipped with advanced semi-cryogenic technology.

• Rhumi-1 is capable of carrying three Cube Satellites and 50 Pico Satellites will reach an altitude of 35 kilometres to sub-orbital altitudes, making it a groundbreaking tool for educational and research purposes.

• Note: Cube satellites are a class of nanosatellites, weighing between 1-10 kg where as Pico satellites are small satellites that typically weigh between 0.1 and 1 kg.

Features of RHUMI-1

• Hybrid Rocket Engine: RHUMI-1 is a hybrid rocket engine that uses a combination of solid and liquid propellants to improve efficiency and reduce operational costs.

• Adjustable Launch Angle: Precise adjustments from 0 to 120 degrees allow for meticulous control over its trajectory.

• Electrically Triggered Parachute System: An innovative, cost-effective, and eco-friendly descent mechanism ensures safe recovery of rocket components.

• Environment Friendly:  RHUMI is 100% pyrotechnic-free and 0% TNT.

Reusable Rockets

• Reusable rockets release the payload, lands back on Earth and can again be launched with new payload. 

Benefits

• Cost Savings: Up to 65% cheaper than building a new rocket for every launch. 

• Reduce Space Debris: By minimizing discarded rocket components.

• Increased launch frequency: Lesser turnaround time enables the rocket to be used more frequently.
