🚀 SOLVE: ISRO Successfully Tests Solid Motor for Gaganyaan Mission
🔥 Why in News?
The Indian Space Research Organisation (ISRO) successfully conducted the first ground test of the SOLVE solid motor at the Static Test Facility, Satish Dhawan Space Centre (SDSC-SHAR), Sriharikota. This marks an important milestone in India's Gaganyaan Human Spaceflight Mission.
📌 What is SOLVE?
SOLVE stands for Sub-Orbital Launch Vehicle for Experiments.
It is a specially designed launch vehicle developed by ISRO to test the Crew Module Deceleration System (parachute recovery system) before sending astronauts into space.
🎯 Objectives of SOLVE
- Validate the parachute recovery system of the Crew Module.
- Carry the Crew Module to an altitude of 10–17 km.
- Ensure safe separation and controlled descent.
- Achieve safe sea splashdown using a 10-parachute recovery system.
