ЁЯФе 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.
ЁЯУМ 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.
ЁЯОп 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.
