Context:
The Defence Research and Development Organisation (DRDO) successfully tested a high-strength drogue parachute for the Gaganyaan human spaceflight mission at the Rail Track Rocket Sled (RTRS) facility in Chandigarh, marking a major milestone in India’s preparations for crewed space missions.
Key Highlights:
Technological Development
- The drogue parachute test was conducted on February 18.
- It demonstrates India’s capability to design and manufacture high-strength ribbon parachutes required for human spaceflight missions.
- The system is designed to ensure safe and controlled descent of the crew module.
Collaborative Effort
- The development and testing involved collaboration between:
- DRDO
- Indian Space Research Organisation (ISRO)
- Vikram Sarabhai Space Centre (VSSC)
- Aerial Delivery Research and Development Establishment (ADRDE)
Role in Gaganyaan Mission
- The drogue parachute stabilizes and decelerates the crew capsule during atmospheric descent.
- It prepares the spacecraft for the deployment of main parachutes that ensure safe splashdown in the ocean.
Significance
- The successful test strengthens India’s technological readiness for Gaganyaan, the country’s first human spaceflight program.
- It marks progress toward independent human spaceflight capability, joining a select group of nations with such expertise.
Relevant Prelims Points:
- Gaganyaan Mission
- India’s first human spaceflight program led by ISRO.
- Aims to send Indian astronauts (Vyomnauts) to Low Earth Orbit (LEO) for a short-duration mission.
- Drogue Parachute
- A small parachute deployed during the initial descent phase.
- Used to stabilize and slow down the spacecraft before the main parachutes deploy.
- Low Earth Orbit (LEO)
- Orbit located up to about 2,000 km above Earth’s surface.
- Commonly used for satellites, space stations, and human spaceflight missions.
- ADRDE
- Aerial Delivery Research and Development Establishment, a DRDO laboratory specializing in parachute and aerial delivery systems.
Relevant Mains Points:
Strategic Importance of Human Spaceflight
- Human spaceflight enhances a country’s technological prestige and scientific capabilities.
- It drives innovations in materials science, life-support systems, robotics, and aerospace engineering.
Benefits of the Gaganyaan Programme
- Strengthens India’s space ecosystem and industrial base.
- Promotes private sector participation and space startups.
- Enhances international collaboration in space exploration.
Challenges
